Transporting carbon – How to safely move CO2 from the atmosphere to permanent storage

15 October 2021

Carbon capture

Key points

  • Carbon capture usage and storage (CCUS) offers a unique opportunity to capture and store the UK’s emissions and help the country reach its climate goals.
  • Carbon dioxide (CO2) can be stored in geological reservoirs under the North Sea, but getting it from source to storage will need a large and safe CO2 transportation network.
  • The UK already has a long history and extensive infrastructure for transporting gas across the country for heating, cooking and power generation.
  • This provides a foundation of knowledge and experience on which to build a network to transport CO2.

Across the length of the UK is an underground network similar to the trainlines and roadways that crisscross the country above ground. These pipes aren’t carrying water or broadband, but gas. Natural gas is a cornerstone of the UK’s energy, powering our heating, cooking and electricity generation. But like the country’s energy network, the need to reduce emissions and meet the UK’s target of net zero emissions by 2050 is set to change this.

Today, this network of pipes takes fossil fuels from underground formations deep beneath the North Sea bed and distributes it around the UK to be burned – producing emissions. A similar system of subterranean pipelines could soon be used to transport captured emissions, such as CO2, away from industrial clusters around factories and power stations, locking them away underground, permanently and safely.

The rise of CCUS technology is the driving force behind CO2 transportation. The process captures CO2 from emissions sources and transports it to sites such as deep natural storage enclaves far below the seabed.

Bioenergy with carbon capture and storage (BECCS) takes this a step further. BECCS uses sustainable biomass to generate renewable electricity. This biomass comes from sources, such as forest residues or agricultural waste products, which remove CO2 from the atmosphere as they grow. Atmospheric CO2 released in the combustion of the biomass is then captured, transported and stored at sites such as deep geological formations.

Across the whole BECCS process, CO2 has gone from the atmosphere to being permanently trapped away, reducing the overall amount of CO2 in the atmosphere and delivering what’s known as negative emissions.

BECCS is a crucial technology for reaching net zero emissions by 2050, but how can we ensure the CO2 is safely transported from the emissions source to storage sites?

Moving gases around safely

Moving gases of any kind through pipelines is all about pressure. Gases always travel from areas of high pressure to areas of low pressure. By compressing gas to a high pressure, it allows it to flow to other locations. Compressor stations along a gas pipeline help to maintain right the pressure, while metering stations check pressure levels and look out for leaks.

The greater the pressure difference between two points, the faster gases will flow. In the case of CO2, high absolute pressures also cause it to become what’s known as a supercritical fluid. This means it has the density of a liquid but the viscosity of a gas, properties that make it easier to transport through long pipelines.

Since 1967 when North Sea natural gas first arrived in the UK, our natural gas transmission network has expanded considerably, and is today made up of almost 290,000 km of pipelines that run the length of the country. Along with that physical footprint is an extensive knowledge pool and a set of well-enforced regulations monitoring their operation.

While moving gas through pipelines across the country is by no means new, the idea of CO2 transportation through pipelines is. But it’s not unprecedented, as it has been carried out since the 1980s at scale across North America. In contrast to BECCS, which would transport CO2 to remove and permanently store emissions, most of the CO2 transport in action today is used in oil enhanced recovery – a means of ejecting more fossil fuels from depleted oil wells. However, the principle of moving CO2 safely over long distances remains relevant – there are already 2,500 km of pipelines in the western USA, transporting as much as 50 million tonnes of CO2 a year.

“People might worry when there is something new moving around in the country, but the science community doesn’t have sleepless nights about CO2 pipelines,” says Dr Hannah Chalmers, from the University of Edinburgh. “It wouldn’t explode, like natural gas might, that’s just not how the molecule works. If it’s properly installed and regulated, there’s no reason to be concerned.”

CO2 is not the same as the methane-based natural gas that people use every day. For one, it is a much more stable, inert molecule, meaning it does not react with other molecules, and it doesn’t fuel explosions in the same way natural gas would.

CO2 has long been understood and there is a growing body of research around transporting and storing it in a safe efficient way that can make CCUS and BECCS a catalyst in reducing the UK’s emissions and future-proofing its economy.

Working with CO2 across the UK

Working with CO2 while it is in a supercritical state mean it’s not just easier to move around pipes. In this state CO2 can also be loaded onto ships in very large quantities, as well as injected into rock formations that once trapped oil and gas, or salt-dense water reserves.

Decades of extracting fossil fuels from the North Sea means it is extensively mapped and the rock formations well understood. The expansive layers of porous sandstone that lie beneath offer the UK an estimated 70 billion tonnes of potential CO2 storage space – something a number of industrial clusters on the UK’s east coast are exploring as part of their plans to decarbonise.

Drax is already running a pilot BECCS project at its power station in North Yorkshire. As part of the Zero Carbon Humber partnership and wider East Coast Cluster, Drax is involved in the development of large scale carbon storage capabilities in the North Sea that can serve the Humber and Teesside industrial clusters. As Drax moves towards its goal of becoming carbon negative by 2030, transporting CO2 safely at scale is a key focus.

“Much of the research and engineering has already been done around the infrastructure side of the project,” explains Richard Gwilliam, Head of Cluster Development at Drax. “Transporting and storing CO2 captured by the BECCS projects is well understood thanks to extensive engineering investigations already completed both onshore and offshore in the Yorkshire region.”

This also includes research and development into pipes of different materials, carrying CO2 at different pressures and temperatures, as well as fracture and safety testing.

The potential for the UK to build on this foundation and progress towards net zero is considerable. However, for it to fully manifest it will need commitment at a national level to building the additional infrastructure required. The results of such a commitment could be far reaching.

In the Humber alone, 20% of economic value comes from energy and emissions-intensive industries, and as many as 360,000 jobs are supported by industries like refining, petrochemicals, manufacturing and power generation. Putting in place the technology and infrastructure to capture, transport and store emissions will protect those industries while helping the UK reach its climate goals.

It’s just a matter of putting the pipes in place.

Enviva Cottondale pellet plant catchment area analysis

18 August 2021

Sustainable bioenergy

The Enviva Cottondale pellet mill has a production capacity of 760,000 metric tonnes of wood pellets annually. Raw material used by the mill includes a combination of roundwood, chips, and secondary residuals (i.e., sawdust and shavings), with pine accounting for 80‐90% of total feedstock. In October 2018, Hurricane Michael passed through the centre of the Cottondale catchment area, causing significant damage to the forest resource with more than 500,000 hectares (ha) of forestland destroyed and an estimated loss of 42 million m3of timber (equivalent to around 4 times the UK annual production of roundwood).

This event has had an impact on the data trends for forest inventory, growth and harvesting removals – as harvesting levels were increased to salvage as much timber as possible before it became unusable due to decay. This can be clearly seen in many of the charts below. However, these forest areas have been restored and now continue to grow, allowing the catchment area to return to its pre-hurricane trends in the medium term.

Forest Area 

The catchment area around Enviva’s Cottondale pellet mill includes 4.3 million ha of land, based on the historical feedstock sourcing patterns of the mill. Timberland represents 68.7% (2.95 million ha) of the total land area in the Cottondale catchment area, this has increased slightly since 2000 from 67.8% and can be considered to have remained stable over this time period.  There are also around 300,000 ha of woodland (associated with agricultural land) and around 800,000 ha of cropland and pastureland.  Forestry is the dominant land use in this catchment area (Figure 1).

Figure 1: Land area by usage

Planted pine represents 33% of the timberland area, natural pine 20%, with 10% mixed stands and the remainder being hardwood forest of which 94% is naturally regenerated (Figure 2).  The breakdown of forest type and species composition has remained relatively stable and largely unchanged over the last 20 years, in contrast to other parts of the US South where some natural pine stands have been converted to planted pine. The pine and mixed forest areas are actively managed and produce the majority of the timber harvest in the catchment area. Despite the large area of hardwood forest, management and timber production is limited. Much of this area is classified as bottomland hardwood located alongside rivers, streams, and creeks and in streamside management zones (SMZs), which restricts active management. In addition, the proportion of this catchment area located in Florida contains a large area of swampland, which is largely composed of hardwoods and cannot be actively managed for timber production and is recognised as having important ecological value.

Figure 2: Breakdown of forest type

Volume and Growth

The overall trend of volume and growth in the Cottondale catchment area is of a maturing forest resource and an increasing accumulation of standing volume, particularly in the larger forest product classes (saw-timber and chip-n-saw). Figure 3 shows that total standing volume increased by 64 million m3 from 2000 to 2018, with the largest increases in the pine saw-timber and chip-n-saw categories. In 2018, the devastating impact of Hurricane Michael caused a substantial reduction in the standing volume across every product category with the total standing volume being reduced by 42 million m3. This event has had a significant impact on the forest resource and is a primary cause of recent data trends.

However, the overall long-term trend in the catchment area is of maturing forest and increasing inventory. This should continue in the long-term once the impact of the hurricane damage has been managed and replacement forest areas begin to mature.

Figure 3: Standing volume by product category

Pine pulpwood inventory increased steadily by around 8 million m3 from 2000 to 2013, reaching a peak of 49 million m3. This then declined slightly to 46 million m3 in 2018 due to the maturing age class of the forest and pulpwood forest growing into the larger size class of chip-n-saw and saw-timber forest (Figure 4), in addition to an increase in pulpwood demand as biomass markets became operational and ramped up production. Following the hurricane in 2018, the pine pulpwood inventory dropped by more than 10 million m3. 

Replanting and reforestation of damaged areas will ensure that future pine pulpwood production will increase again once these forests start to mature.

In the period from 2000 to 2018 pine sawtimber standing volume increased by 41.5 million m3 (78%) and chip-n-saw by 19.6 million m3 (73%), indicating a maturing age class and a growing forest resource. The 2018 hurricane caused a reduction in standing volume in both of these product categories of 11.6 and 8 million m3respectively (12% and 17% of the 2018 volume). However, the increasing trend is likely to continue once the forest area recovers.

Figure 4: Standing volume by product category

The growth drain ratio (GDR) is the comparison of average annual growth to removals (typically harvesting), where the growth exceeds removals the GDR will be in excess of 1 and this is considered sustainable, where removals exceed growth then the GDR will be less than 1 and this is not sustainable if maintained in the long-term – although in the short-term this can be a factor of large areas of mature forest with low growth rates and high rates of harvesting, short periods of high demand for a particular product or salvage harvesting after a natural disturbance. The GDR should be considered over a longer time period to ensure it reflects the long-term trend. In the period from 2003 to 2020 the combined GDR for pine products averaged 1.52 with a high of 1.84 and a low of 1.08 (Figure 5).

Figure 5: Growth to drain ratio by product category

The maturing forest resources can be clearly seen from the growth to removals data for each product category. Average tree sizes getting larger and more pulpwood class stands moving into the larger saw-timber and chip-n-saw categories. This trend can be seen by comparing the data values from 2003 and 2018 where saw-timber average annual growth increased by 90% (1.6 million m3), and removals by 41% (0.98 million m3).  Chip-n-saw growth increased by 73% (1.3 million m3) whilst removals increased by 160% (1.9 million m3). Pulpwood growth decreased by 7.5% (0.4 million m3) whilst removals increased by 63% (1.6 million m3).  Over this time period the total annual surplus of pine growth compared to removals averaged 3.7 million m3 per year (Figure 6).

Figure 6: Pine growth and removals by product category and year

Hardwood saw-timber and pulpwood removals declined by 20% and 40% respectively between 2000 and 2018, whilst growth increased by 23% for hardwood saw-timber and declined by 16% for hardwood pulpwood. The average annual hardwood surplus over this time period was 1.5 million m3 per year (Figure 7).

Figure 7: Hardwood growth and removals by product category and year

Despite a short-term imbalance in some product categories, the overall surplus of pine growth compared to removals has remained strong, with an average of 3.3 million m3 between 2000 and 2020, which includes the increased salvage harvesting in 2018 (Figure 8).

Figure 8: Cumulative annual surplus of growth compared to removals

Wood Prices

Stumpage price is the value paid to the forest owner for each category of product at the time of harvesting. The variation in prices in the Cottondale catchment area has been significant and shows some interesting trends. The higher value pine products (saw-timber and chip-n-saw) began with high stumpage values in 2000, as markets were strong for construction and furniture grade timber and supply limited at that stage due to the young age class and predominance of pulpwood stands at that time.  In 2008, following the global economic crisis and the crash in housing and construction markets, saw-timber prices declined substantially reaching a low of $23 per ton, a 47% decline from the 2000 price. This stumpage price has never recovered, despite an improvement in the economy and an increase in housing starts and demand for structural timber. The reason for the continued deflated saw-timber stumpage price is a substantial surplus of supply in this catchment area.  As the forest area has matured and more saw-timber grade stands are available, markets have been able to satisfy demand without an increase in price.

Pine pulpwood prices at Cottondale were lower than the US South-wide average in 2000 and remained relatively low until around 2013. A reduction in saw-timber production, and consequent reduction in mill residuals, due to the recession of 2008, led to a shortage of pulp mill feedstock and increased harvesting of pulpwood stands. This caused an increase in pine pulpwood stumpage values alongside an overall increase in demand as biomass and pellet markets began production around this time. The data shows a short-term spike in pine pulpwood stumpage prices in 2013-14, but this returned to a more normal trend as more saw-timber residues became available and pulpwood stumpage values have been around $10-11 per ton since 2015 (Figure 9).

Figure 9: Variation in stumpage value over time

Biomass demand 

Biomass demand in the Cottondale catchment area began in 2008 and has averaged around 800 thousand m3per year since that time with a high of just over 1 million m3 in 2013 to 2015 and a low of 200 thousand m3 in 2008. Other pulpwood markets have had an average annual demand of 3.97 million m3 between 2000 and 2020 with a high of 4.76 million m3 in 2018 and a low of 3.2 million m3 in 2009.  In 2020 the biomass market represented 16% of the total pulpwood demand in the Cottondale catchment area (Figure 10).

Figure 10: Total pulpwood demand

Forest Management

The average size of clear-cut harvesting sites from 2000 to 2020 has been 47 ha, ranging from 38 ha up to 56 ha. The average size of thinning sites has been 65 ha, ranging from 55 ha up to 76 ha. When isolating the period from 2000 to 2010 and 2011 to 2020, the averages and range remain very similar, suggesting that there has been no significant change in harvesting coupe size over this period.

Figure 11: Average size of harvesting sites

The impact of biomass and wood pellet demand on the key metrics in this catchment area are considered below. This is a summary of Hood Consulting’s view on the trends and impacts in the Cottondale catchment area.

Is there any evidence that bioenergy demand has caused the following:

Deforestation?

No. US Forest Service (USFS) data shows a 55,166-hectare (+1.9%) increase in the total area of timberland in the Enviva Cottondale catchment area since the Enviva Cottondale pellet mill commenced production in 2008. Furthermore, a strong positive relationship was identified between biomass demand and timberland area, suggesting that the increase in timberland area since 2008 can be linked, to a degree, to increased demand attributed to bioenergy.

A change in management practices (rotation lengths, thinnings, conversion from hardwood to pine)?

Inconclusive. Changes in management practices have occurred in the catchment area over the last two decades. However, the evidence is inconclusive as to whether increased demand attributed to bioenergy has caused or is responsible for these changes.

Clearcuts and thinnings are the two major types of harvests that occur in this region, both of which are long-standing, widely used methods of harvesting timber. TimberMart-South (TMS) data shows that thinnings accounted for 63% of total reported harvest area in the Cottondale market from 2005-2011 but only 39% of total harvest area reported from 2012-2020. Specifically, the decreased prevalence of thinning since 2012 can be linked to the strengthening of pine pulpwood markets and concurrent weakening of pine sawtimber markets beginning in the mid-2000s.

Prior to the bursting of the US housing bubble in 2006, timber management in this market had been driven to a large degree by pine sawtimber production. However, challenging market conditions saw pine sawtimber stumpages prices decline more than 40% from 2006-2011. At the same time, pine pulpwood markets started to strengthen, with pine pulpwood stumpage prices increasing more than 50% from 2006-2010. So, with sawtimber markets weakening and pulpwood markets strengthening, the data suggests that many landowners decided to alter their management approach (i.e. to take advantage of strong pulpwood markets) and focus on short pulpwood rotations that typically do not utilize thinnings.

Bioenergy has had an impact on this market by adding an average of roughly 680,000 metric tons of additional pine pulpwood demand to this catchment area annually since 2008. However, bioenergy has accounted for only 17% of total softwood pulpwood demand in this market since Enviva Cottondale’s startup. Ultimately, the shift in management approach that occurred in this market can be more closely linked to other factors, such as increased softwood pulpwood demand from non-bioenergy sources (i.e. pulp/paper) as well as the weakening of pine sawtimber markets.

Diversion from other markets?

No. Demand for softwood (pine) sawlogs increased an estimated 23% in the Cottondale catchment area from 2008-2020. Also, there is no evidence that increased demand from bioenergy has caused a diversion from other softwood pulpwood markets (i.e. pulp/paper), as softwood pulpwood demand not attributed to bioenergy has increased 25% since the Cottondale mill’s startup in 2008.

An unexpected or abnormal increase in wood prices?

Inconclusive. The startup of Enviva Cottondale added more than 900,000 metric tons of softwood pulpwood demand to the catchment area from 2008-2013, and this increase in demand coincided with a 28% increase in the delivered price of pine pulpwood (PPW) – the primary roundwood product consumed by the Enviva Cottondale mill. However, since 2013, delivered PPW prices have held flat, despite biomass-related softwood pulpwood demand falling to an average of roughly 635,000 tons per year since 2016, down more than 40% compared to 2013 peak levels. (Note the decrease in roundwood consumption was due to a higher utilization of secondary residuals). It’s also important to point out that the roughly 410,000-metric ton decrease in softwood biomass demand from 2013 to 2020 was offset by a roughly 455,000-metric ton increase in softwood pulpwood demand from other sources.

Statistical analysis did identify a positive relationship between softwood biomass demand and delivered PPW price. However, that relationship was found to be relatively weak. The relationship between delivered PPW price and softwood pulpwood demand from other sources was found to be much stronger, which was not unexpected to find given that softwood pulpwood demand not attributed to bioenergy has accounted for 83% of total softwood pulpwood demand in the catchment area since 2008.

Furthermore, there is some evidence linking the increase in pine sawmill chip prices to increased consumption of secondary pine residuals by Enviva Cottondale. Specifically, consumption of secondary pine residuals by Enviva Cottondale more than doubled from roughly 213,000 metric tons in 2012 to nearly 490,000 metric tons in 2016, and this increased consumption of pine residuals coincided with a nearly 20% increase in the price of pine sawmill chips. However, increased consumption of residuals by the bioenergy sector was only one of several contributing factors that can be linked to the increase in pine sawmill chip prices. Increased consumption of pine residuals by the pulp/paper industry also contributed to higher pine sawmill chip prices. In addition, there is a strong linkage between pine sawmill chip prices and softwood lumber production. Specifically, the increase in softwood lumber production that begun in the early-to-mid-2010s consequently resulted in the increased production of secondary residuals, and the increased availability of this lower-cost material led to greater competition and ultimately higher pine residual prices.

A reduction in growing stock timber?

No. From 2008 (the year Enviva Cottondale commenced production) up until Hurricane Michael struck in late-2018, total growing stock inventory increased an average of 1.8% per year (+19% total) in the Cottondale catchment area. Specifically, inventories of pine sawtimber and pine chip-n-saw increased 58% and 28%, respectively, while pine pulpwood (PPW) inventory decreased 4% over this same period.

However, note that the decrease in pine pulpwood inventory from 2008-2018 was not due to increased demand from bioenergy or increased harvesting above the sustainable yield capacity of the forest area, as annual growth of pine pulpwood exceeded annual removals every year throughout this period. Rather, this slight decrease in PPW inventory levels is more a reflection of the aging of the catchment area forest and the movement of stands classified as pulpwood to stands classified as chip-n-saw.

A reduction in the sequestration rate of carbon?

No. US Forest Service (USFS) data shows the average annual growth rate of total growing stock timber in the Cottondale catchment area decreased from 5.9% in 2008 to 5.2% in 2020, suggesting that the sequestration rate of carbon also declined slightly over this period. However, there is little evidence to suggest that increased demand attributed to bioenergy is responsible for this change.

The reduction in overall growth rate (and therefore reduction in the sequestration rate of carbon) is more a reflection of the aging of the catchment area forest. Specifically, growth rates decline as timber ages, and this is exactly what USFS data shows in the Cottondale catchment area, with the average age of growing stock timber increasing from less than 44 years of age in 2008 to nearly 46 years of age in 2020.

An increase in harvesting above the sustainable yield capacity of the forest area?

No. Growth-to-removals (G:R) ratios, which compare annual timber growth to annual timber removals, provides a measure of market demand relative to supply as well as a gauge of market sustainability. In 2020, the latest available, the G:R ratio for pine pulpwood (PPW), the predominant timber product utilized by the bioenergy sector, equaled 1.26 (recall that a value greater than 1.0 indicates sustainable harvest levels).

Note, however, that the PPW G:R ratio averaged 1.57 in the catchment area from 2013-2017 before falling to 1.20 in 2018 and averaging 1.27 since. This notable drop in 2018 was due to a nearly 35% increase in PPW removals (due to Hurricane Michael). It’s also important to note that while annual removals have moved back in line with pre-Michael levels since 2019, this lower PPW G:R ratio is likely reflective of the new norm (at least over the midterm). Hurricane Michael destroyed an estimated 22% of total pine pulpwood inventory in the Cottondale catchment area, and this loss in inventory will be reflected in reduced growth until the destroyed forests regenerate. However, in spite of this loss, adequate PPW inventory levels still remain and sustainable market conditions are expected to persist moving forward.

Timber growing stock inventory

Neutral. According to USFS data, inventories of pine pulpwood (PPW) decreased 25% in the catchment area from 2008-2020. However, this substantial decrease was due to Hurricane Michael, which destroyed nearly 520,000 hectares of catchment area timberland when it hit the Florida panhandle in late-2018. Prior to this event occurring, PPW inventory levels had held relatively steady, decreasing slightly but averaging 47.2 million m3 in the catchment area from 2008-2018. However, the destruction caused by Hurricane Michael resulted in the immediate loss of more than 10.3 million m3 of PPW inventory, or a 22% decrease compared to pre-hurricane levels.

Moreover, the slight decrease in PPW inventory levels that did occur from 2008-2018 was not due to increased demand from bioenergy. Typically, a reduction in inventory is linked to harvest levels above the sustainable yield capacity of the forest area, but in the Cottondale catchment area, annual growth of PPW exceeded annual removals every year throughout this period. Ultimately, the decrease in PPW inventory from 2008-2018 can be more closely linked to decreased pine sawtimber production beginning in the early to mid-2000s. Specifically, annual removals of pine sawtimber decreased 28% from 2003-2014, and the reduction in harvest levels over this period translated to a reduction in newly-re-established pine stands and ultimately the slight reduction in PPW inventory levels that occurred in the mid-to-late 2010s.

Timber growth rates

Neutral. Overall, timber growth rates declined slightly in the catchment area from 2008 (the year Enviva Cottondale commenced operations) through 2020. However, this decrease in timber growth rates was not due to increased demand attributed to bioenergy but rather to the aging of the catchment area forest. Specifically, USFS data shows the average age timber inventory in the Cottondale catchment area increased from an estimated 43.6 years of age in 2008 to 45.7 years of age in 2020.

Forest area

Positive. In the Enviva Cottondale catchment area, total forest area (i.e. timberland) increased more than 55,100 hectares (+1.9%) from 2008 through 2020, and this increase can be linked to several factors, including increases in softwood pulpwood demand (from both bioenergy and other sources) as well as conversion from farmland.

Specifically, the more than 55,100-hectare increase in catchment area timberland from 2008-2020 coincided with a 1.1-million metric ton increase in annual softwood pulpwood demand (roughly half of which was attributed to bioenergy). While statistical analysis identified moderately strong positive relationships between timberland area and both softwood biomass demand and non-bioenergy-related softwood pulpwood demand, a strong positive correlation was found between timberland and total softwood pulpwood demand – suggesting that the increases in timberland since 2008 can be attributed, in part, to the increase in total softwood pulpwood demand (from both bioenergy and other sources).

The more than 55,100-hectare increase timberland from 2008-2020 also coincided with a roughly 75,000-hectare decrease in farmland (i.e. cropland, woodland, and pastureland) over this period. Specifically, the catchment area experienced a roughly 31,800-hectare loss in cropland, 8,900-hectare loss in pastureland, and 34,300-hectare loss in woodland from 2008-2020. Furthermore, statistical analysis confirmed this inverse relationship, identifying a strong negative correlation between timberland and farmland in the Cottondale catchment area.

Wood prices

Negative / Positive. Total softwood pulpwood demand attributed to bioenergy in the Cottondale catchment area increased from zero tons in 2007 (the year prior to Enviva Cottondale’s startup) to over 1.0 million metric tons in 2013. Over this same period, the price of delivered pine pulpwood (PPW) – the predominant roundwood product utilized by Enviva Cottondale for wood pellet production – increased 42% (from $21.06 per ton in 2007 to $29.82 per ton in 2013).

However, the apparent link between increased softwood biomass demand and increased delivered PPW price is only loosely supported by statistical analysis, which identified a relatively weak positive relationship between these two variables. Furthermore, delivered PPW price has remained nearly unchanged in the catchment area since 2013, despite softwood biomass demand declining and averaging roughly 577,000 metric tons per year since 2016. (Note that the roughly 410,000-metric ton decrease in softwood biomass demand from 2013-2020 was offset by a roughly 455,000-metric ton increase in softwood pulpwood demand from other sources). Ultimately, the increase in delivered PPW prices in the catchment area can be linked to increased demand for softwood pulpwood from all sources, and roughly half of the 1.2-million metric ton increase in softwood pulpwood demand since 2007 can be attributed to bioenergy.

However, it’s also important to note that the increase in bioenergy-related wood demand has been a positive for forest landowners in the Enviva Cottondale catchment area. Not only has bioenergy provided an additional outlet for pulpwood in this market, but the increase in delivered PPW price resulting from increased softwood pulpwood demand from bioenergy has transferred through to landowners in the form of higher PPW stumpage prices. Specifically, over the six years prior to Enviva Cottondale’s startup, PPW stumpage price – the price paid to landowners – averaged roughly $7.40 per ton in the Cottondale catchment area. However, since 2010, PPW stumpage prices have averaged more than $11.15 per ton, representing a more than 50% increase compared to pre-mill startup levels.

Markets for solid wood products

Positive. In the Enviva Cottondale catchment area, demand for softwood sawlogs used to produce lumber and other solid wood products increased an estimated 23% from 2008-2020. This increase in softwood lumber production has consequentially resulted in an increase in sawmill residuals (i.e. chips, sawdust, and shavings) – by-products of the sawmilling process and materials utilized by Enviva Cottondale to produce wood pellets.

Specifically, softwood sawlog demand has increased more than 16% in the catchment area since 2014, and this increase in demand has coincided with a nearly 60% increase in pine residual purchases by Enviva Cottondale. (Note that pine residuals constituted 25% of total raw material purchases by Enviva Cottondale in 2014 but 41% of total raw material purchases in 2020). So, not only has Enviva Cottondale benefited from the greater availability of this sawmill by-product, but lumber producers have also benefited, as Enviva Cottondale has provided an additional outlet for these producers and their by-products.

Carbon capture

What is direct air carbon capture and storage (DACS)?

Direct air carbon capture and storage (DACS, sometimes referred to as DAC or DACCS) is one of the few technologies that can remove carbon dioxide (CO2) from the atmosphere. Unlike other carbon removal technologies that capture CO2 emissions during the process of generating electricity or heat, DACS can be deployed anywhere in the world it can tap into a supply of electricity.

CO2 removal is crucial to meeting the international climate goals set by the 2015 Paris Agreement. But it’s not enough just to cut CO2 emissions, to achieve net zero, it will also be necessary to remove the CO2 that two centuries of industrialisation have released into the environment. As a technology that removes more CO2 from the atmosphere than it releases – assuming it is powered by green electricity – DACS has the potential to play a key role in this process.

Key direct air capture facts

How does DACS work?

DACS could be described as a form of industrial photosynthesis. Just as plants use photosynthesis to convert sunlight and CO2 into sugar, DACS systems use electricity to remove CO2 from the atmosphere using fans and filters.

Air is drawn into the DACS system using an industrial scale fan. Liquid DACS systems pass the air through a chemical solution which removes the CO2 and returns the rest of the air back into the atmosphere.

Solid DACS systems captures CO2 on the surface of a filter covered in a chemical agent, where it then forms a compound. The new compound is heated, releasing the CO2 to be captured and separating it from the chemical agent, which can then be recycled.

The captured CO2 can then be compressed under very high pressure and pumped via pipelines into deep geological formations. This permanent storage process is known as ‘sequestration’.

Alternatively, the CO2 can be pumped under low pressure for immediate use in commercial processes, such as carbonating drinks or cement manufacturing.

A 2021 study by the Coalition for Negative Emissions shows that DACS could provide at least 1Gt of sustainable negative emissions by 2025

DACS fast facts

What role can DACS play in decarbonisation?

CO2 is in the air at the same concentration everywhere in the world. This means that DACS plants can be located anywhere, unlike carbon capture systems that remove CO2 from industrial processes at source.

There are 15 DACS plants currently in operation worldwide – Climeworks operates three in Switzerland, Iceland and Italy. Together, these small-scale plants capture approximately 9,000 tonnes of CO2 per annum. The first large-scale plant, currently being developed in the Permian Basin, Texas, is expected to capture 1,000,000 tonnes (one megatonne) per annum when it becomes operational in 2025.

At just 0.04%, the concentration of CO2 in the atmosphere is very dilute which makes removing and storing it a challenge. This means that DACS costs significantly more than some other CO2 capture technologies – between $200 and $600 (£156-468) per metric tonne. The process also requires large amounts of energy, which adds to the demand for electricity.

However, DACS has the potential to become an important piece in the jigsaw of CO2 removal technologies and techniques that includes nature-based solutions such as planting forests, along with bioenergy with carbon capture and storage (BECCS), soil sequestration and ‘blue carbon’ marine initiatives.

What is bioenergy with carbon capture and storage (BECCS)?

18 May 2021

Carbon capture

What is bioenergy with carbon capture and storage (BECCS)? 

Bioenergy with carbon capture and storage (BECCS) is the process of capturing and permanently storing carbon dioxide (CO2) from biomass (organic matter) energy generation.

Why is BECCS important for decarbonisation? 

Bioenergy has very low net carbon emissions when biomass is sustainably sourced from forests that are managed to regrow at least as fast as they are harvested. This means that carbon taken up by the regrowing forests compensates for the carbon released when biomass is combusted.

When sustainable bioenergy is paired with carbon capture and storage it becomes a source of negative emissions, as CO2 is permanently removed from the carbon cycle.

Experts believe that negative emissions technologies (NETs) are crucial to helping countries meet the long-term goals set out in the Paris Climate Agreement. As BECCS is the most scalable of these technologies this decade, it has a key role to play in combating climate change.

How is the bioenergy for BECCS generated?

Most bioenergy is produced by combusting biomass as a fuel in boilers or furnaces to produce high-pressure steam that drives electricity-generating turbines. Alternatively, bioenergy generation can use a wide range of organic materials, including crops specifically planted and grown for the purpose, as well as residues from agriculture, forestry and wood products industries. Energy-dense forms of biomass, such as compressed wood pellets, enable bioenergy to be generated on a much larger scale. Fuels like wood pellets can also be used as a substitute for coal in existing power stations.

How is the carbon captured?

BECCS uses a post-combustion carbon capture process, where solvents isolate CO2 from the flue gases produced when the biomass is combusted. The captured CO2 is pressurised and turned into a liquid-like substance so it can then be transported by pipeline.

How is the carbon stored?

Captured CO2 can be safely and permanently injected into naturally occurring porous rock formations, for example unused natural gas reservoirs, coal beds that can’t be mined, or saline aquifers (water permeable rocks saturated with salt water). This process is known as sequestration.

Over time, the sequestered CO2 may react with the minerals, locking it chemically into the surrounding rock through a process called mineral storage.

BECCS fast facts

  • Two 600+ megawatt (MW) biomass units, upgraded with carbon capture technology, could deliver 40% of the negative emissions the Climate Change Committee indicates will be needed from BECCS for the UK to reach net-zero by 2050
  • BECCS has the potential to remove 20-70 million tonnes of CO2 per year in the UK by 2050
  • All National Grid’s Net Zero Future Energy Scenarios (FES) deploy BECCS by 2028 and see a rapid increase in capacity in the 2030s
  • There are 70 billion tonnes of potential CO2 storage space around the UK, according to the British Geological Survey

Is BECCS sustainable?

 Bioenergy can be generated from a range of biomass sources ranging from agricultural by-products to forestry residues to organic municipal waste. During their lifetime plants absorb CO2 from the atmosphere, this balances out the CO2that is released when the biomass is combusted.

What’s crucial is that the biomass is sustainably sourced, be it from agriculture or forest waste. Responsibly managed sources of biomass are those which naturally regenerate or are replanted and regrown, where there’s a increase of carbon stored in the land and where the natural environment is protected from harm.

Biomass wood pellets used as bioenergy in the UK, for example, are only sustainable when the forests they are sourced from continue to grow. Sourcing decisions must be based on science and not adversely affect the long-term potential of forests to store and sequester carbon.

Biomass pellets can also create a sustainable market for forestry products, which serves to encourage reforestation and afforestation – leading to even more CO2 being absorbed from the atmosphere.

Global collaboration
is key to tackling
the climate crisis

Will Gardiner, Chief Executive Officer, Drax Group

22 April 2021

Opinion

Leaders from 40 countries are meeting today, albeit virtually, as part of President Joe Biden’s Leaders’ Summit on Climate. The event provides an opportunity for world leaders to reaffirm global efforts in the fight against climate change, set a clear pathway to net zero emissions, while creating jobs and ensuring a just transition.

Since taking office President Biden has made bold climate commitments and brought the United States back into the Paris Agreement. Ahead of the two-day summit, he announced an ambitious 2030 emissions target and new Nationally Determined Contributions. The US joins other countries that have announced significant reduction goals. For example, the EU committed to reduce its emissions by at least 55%, also South Korea, Japan and China have all set net-zero targets by mid-century.

Here in the UK, Prime Minister Boris Johnson this week outlined new climate commitments that will be enshrined in law. The ambitious new targets will see carbon emissions cut by 78% by 2035, almost 15 years earlier than previously planned. If delivered, this commitment which is in-line with the recommendations of the Climate Change Committee’s sixth carbon budget will put the UK at the forefront of climate action, and for the first time the targets include international aviation and shipping.

What makes climate change so difficult to tackle is that it requires collaboration from many different parties on a global scale never seen before. As a UK-North American sustainable energy company, with communities on both sides of the Atlantic, at Drax we are keenly aware of the need for thinking that transcends borders, creating a global opportunity for businesses and governments to work together towards a shared climate goal. That’s why we joined other businesses and investors in an open letter supporting the US government’s ambitious climate actions.

Collaboration between countries and industries

It’s widely recognised that negative emissions technologies will be key to global efforts to combat climate change.

At Drax we’re pioneering the negative emissions technology bioenergy with carbon capture and storage (BECCS) at our power station in North Yorkshire, which when up and running in 2027 will capture millions of tonnes of carbon dioxide (CO2) per year, sending it for secure storage, permanently locking it away deep under the North Sea.

Experts on both sides of the Atlantic consider BECCS essential for reaching net zero. The UK’s Climate Change Committee says it will play a major role in removing CO2 emissions that will remain in the UK economy after 2050 from industries such as aviation and agriculture that will be difficult to fully decarbonise. Meanwhile, a report published last year by New York’s Columbia University revealed that rapid development of BECCS is needed within the next 10 years in order to curb climate change and a recent report from Baringa, commissioned by Drax, showed it will be a lot more expensive for the UK to reach its legally binding fifth carbon budget between 2028 and 2031 without BECCS.

A shared economic opportunity

Globally as many as 65 million well-paid jobs could be created through investment in clean energy systems. In the UK, BECCS and negative emissions are not just essential in preventing the impact of climate change but will also be a key component of a post-Covid economy.

Government and private investments in clean energy technologies can create thousands of well-paid jobs, new careers, education opportunities and upskill workforces. Developing BECCS at Drax Power Station, for example, would support around 17,000 jobs during the peak of construction in 2028, including roles in construction, local supply chains and the wider economy. It would also act as an anchor project for the Zero Carbon Humber initiative, which aims to create the world’s first net zero industrial cluster. Developing a carbon capture, usage, and storage (CCUS) and hydrogen industrial cluster could spearhead the creation and support of tens of thousands of jobs across the Humber region and more than 200,000 around the UK in 2039.

Under the Humber Bridge

Additional jobs would be supported and created throughout our international supply chain. This includes the rail, shipping and forestry industries that are integral to rural communities in the US South and Western Canada.

A global company

As a British-North American company, Drax embodies the positive impact that clean energy investments have. We directly employ 3,400 people in the US, Canada, and the UK, and indirectly support thousands of families through our supply chains on both sides of the Atlantic. Drax is strongly committed to supporting the communities where we operate by investing in local initiatives to support the environment, jobs, education, and skills.

From the working forests of the US South and Western Canada to the Yorkshire and Humber region, and Scotland, we have a world-leading ambition to be carbon negative by 2030. At Drax, we believe the challenge of climate change is an opportunity to improve the environment we live in. We have reduced our greenhouse gas emissions by over 80% and transformed into Europe’s largest decarbonisation project. Drax Power Station is the most advanced BECCS project in the world and we stand ready to invest in this cutting-edge carbon capture and removal technology. We can then share our expertise with the rest of the world – a world where major economies are committing to a net zero future and benefiting from a green economic recovery.

If we are to reach the targets set in Paris, global leaders must lock in this opportunity and make this the decade of delivery.

The world’s leading sustainable biomass generation and supply business

Will Gardiner, Chief Executive Officer, Drax Group

13 April 2021

Opinion

Today we completed a transformational deal – our acquisition of Canadian biomass pellet producer Pinnacle Renewable Energy.

I’m very excited about this important acquisition and welcoming our new colleagues to the Drax family – together we will build on what we have already achieved, having become the biggest decarbonisation project in Europe and the UK’s largest single site renewable power generator as a result of us using sustainable biomass instead of coal.

The deal positions Drax as the world’s leading sustainable biomass generation and supply business – making us a truly international business, trading biomass from North America to Europe and Asia. It also advances our strategy to increase our self supply, reduces our biomass production costs and creates a long-term future for sustainable biomass – a renewable energy source that the UN’s IPCC says will be needed to achieve global climate targets.

It’s also an important milestone in Drax’s ambition to become a carbon negative company by 2030 and play an important role in tackling the global climate crisis with our pioneering negative emissions technology BECCS.

That’s because increasing our annual production capacity of sustainable biomass while also reducing costs helps pave the way for our plans to use bioenergy with carbon capture and storage (BECCS) at Drax.

Negative emissions from BECCS are vital to address the global climate emergency while also providing the renewable electricity needed for a net zero economy, supporting jobs and clean growth in a post-Covid recovery.

We already know Pinnacle well – it is one of our key suppliers and the company is a natural fit with Drax.

Our new colleagues have a wealth of operational and commercial expertise so I’m looking forward to seeing what we can achieve together.

We will benefit from Pinnacle’s scale, operational efficiency and low-cost fibre sourcing, that includes a high proportion of sawmill residues. In 2019, Pinnacle’s production cost was 20% lower than Drax’s.

Completing this deal will increase our annual production capacity to 4.9 million tonnes of sustainable biomass pellets at 17 plants in locations across Western Canada and the US South – up from 1.6Mt now.

It also expands our access to three major North American fibre baskets and four export facilities, giving us a large and geographically diversified asset base, which enhances our sourcing flexibility and security of supply.

This positions us well to take advantage of the global growth opportunities for sustainable biomass. The market for biomass wood pellets for renewable generation in Europe and Asia is expected to grow in the current decade, principally driven by demand in Asia.

We believe that with increasingly ambitious global decarbonisation targets, the need for negative emissions and improved understanding of the role that sustainably sourced biomass can play, will result in continued robust demand.

Pinnacle is already a key supplier of wood pellets to other markets with C$6.7 billion of long-term contracts with high quality Asian and European customers, including Drax, and a significant volume contracted beyond 2027.

Drax aims to leverage Pinnacle’s trading capability across its expanded portfolio. We believe that the enlarged supply chain will provide greater opportunities to optimise the supply of biomass from its own assets and third-party suppliers.

The transport and shipping requirements of the enlarged company will provide further opportunities to optimise delivery logistics, helping to reduce distance, time, carbon footprint and cost.

Train transporting biomass wood pellets arriving at Drax Power Station

Importantly – there will also be opportunities to share best practice and drive sustainability standards higher across the group.

We recognise that the forest landscape in British Columbia and Alberta is different to the commercially managed forests in the south eastern US where we currently operate.

In line with our world leading responsible sourcing policy, Drax will work closely with environmental groups, Indigenous First Nation communities and other stakeholders and invest to deliver good environmental, social and climate outcomes in Pinnacle’s sourcing areas.

We are determined to create a long-term future for sustainable biomass and deliver BECCS –  the negative emissions technology that will be needed around the world to meet global climate targets. The acquisition of Pinnacle takes us a big step forward in achieving our goals.

At the heart of the energy transition

Will Gardiner, Chief Executive Officer, Drax Group

19 March 2021

Opinion
Tree nursery in Mississippi

Will Gardiner opened the second day of the Chatham House Energy Transitions conference. Watch his keynote address below or scroll down the page to read his speech in full.

The energy transition is central to our purpose of enabling a zero carbon, lower cost energy future.

Drax has been at the heart of Britain’s energy system for decades. And we have played a key role in the decarbonisation of the power sector: Drax Power Station in Selby, North Yorkshire, is the UK’s largest power station and Europe’s largest decarbonisation project. Cruachan, our Scottish Pumped Storage facility is a key complement to Britain’s ever increasing supply of offshore wind.

Our transition from coal to biomass has allowed us to reduce our greenhouse gas emissions by over 80% while providing clean and flexible energy to millions of homes and businesses across the UK. This month saw the end of commercial coal generation at Drax power station – a milestone in the history of our company and of the UK economy, too.

But the scale of the climate crisis means that we cannot stop here.

Which is why we have committed to a world-leading ambition to be carbon negative by 2030.

We will achieve this by making a transformational investment in bioenergy with CCS, or BECCS, which will enable us to permanently remove carbon emissions from the atmosphere while continuing to supply the renewable electricity that millions of British homes and businesses depend upon.

Today, we are pioneering BECCS at Drax Power Station as part of the Zero Carbon Humber Cluster, a coalition of diverse businesses with one ambition: to create the world’s first net zero emissions industrial cluster.

The benefits are enormous

BECCS is a vital technology in the fight against climate change. Expert bodies such as the Climate Change Committee here in the UK and the IPCC at a global level are clear that we need negative emissions technologies including BECCS to reach net zero, and BECCS is central to the UK and Europe’s decarbonisation plans.

As the world’s largest, and most experienced, generator and supplier of sustainable bioenergy there is no better place to pioneer BECCS than at Drax. The economic, social and environmental benefits are enormous.

BECCS at Drax will permanently remove millions of tonnes of carbon from the atmosphere and help heavy industry in the UK’s largest emitting area decarbonise quickly and cost effectively;

It will enable the creation of tens of thousands of green jobs in the North of England, levelling up the economy and delivering a green recovery from the Covid crisis;

And it will put the UK at the forefront of global efforts to develop carbon removal technology in this, the year that we host COP26 in Glasgow.

The scale of the climate crisis means that we cannot stop here.

A proven technology

We know that BECCS works and that the technology is available now. Looking at cost projections from the CCC, we also know that it is the best value negative emissions technology.

Engineer at BECCS pilot project within Drax Power Station

Engineer at BECCS pilot project within Drax Power Station

We have already successfully run two BECCS pilots at the power station. In 2019 we demonstrated that we can capture CO2 from a 100% biomass feedstock. And in 2020, we began a second pilot working with Mitsubishi Heavy Industries to further enhance the potential for delivering negative emissions.

We aim to deploy BECCS at scale by 2027. To that end, earlier this month, we kickstarted the planning process for our proposals to build our first BECCS units, marking a major milestone in the project and putting us in a position to commence building BECCS as soon as 2024.

The support we need

Drax Power Station has a proud history of transformation. And today we are making rapid progress in further decarbonising our operations and making bold commitments about our future.

The core of our successful decarbonisation has been a close partnership with government. And it is this partnership that will make BECCS a reality and enable the multiple benefits that come with it. An effective negative emissions policy and regulatory framework from government will enable further investments from companies such as Drax.

We believe it is possible for such a policy framework to emerge in the coming months.

With COP26 later this year, making that policy commitment will allow us to accelerate our own decarbonisation journey and support the industries of the future here in the UK.

BECCS in context

But we know that there is no silver bullet solution to tackling climate change.

Negative emissions technologies such as BECCS will be needed alongside others, for example more renewables, electric vehicles, energy storage, energy efficiency and hydrogen.

BECCS will enable us to permanently remove carbon emissions from the atmosphere while continuing to supply the renewable electricity that millions of British homes and businesses depend upon.

BECCS complements – and does not – and should not – substitute for ambitious decarbonisation plans. Technologies such as BECCS have a clear and unique role to play by helping harder to abate sectors such as heavy industry, aviation and agriculture – decarbonise.

This is critically important if we are to meet our legally binding 2050 net zero target. The CCC estimates that 51m tonnes of CO2 will need to be captured via BECCS to meet net zero.

Sustainability at our core

We know that BECCS can only make a meaningful contribution to tackling climate change if the bioenergy is sustainably sourced. This has been fundamental to Drax’s transition from coal to biomass, and it remains fundamental as we progress our plans for BECCS.

Infographic showing how BECCS removes carbon from the atmosphere

Biomass, as the UK Government has stated, is one of our most valuable tools for reaching net zero emissions. So we need the right framework to ensure it is sourced sustainably.

As the world’s largest bioenergy producer and generator, we recognise our responsibility to be the world leaders in sustainability, too.

At Drax, we have invested in world leading policies, tools and expertise to ensure that our biomass is sustainably sourced. We go beyond regulatory compliance and have set up an Independent Advisory Board, Chaired by the UK Government’s former Chief Scientific Advisor, to help us and challenge us on sustainable biomass and its role in Drax’s transition to net zero.

Thanks to our independent catchment area analyses, we know more about the forests we source from than ever before. We know and can demonstrate how demand for biomass can support healthy forests. For example, in the South East US where Drax sources most of its biomass, there is more than double the carbon stored in forests than there was 50 years ago.

A partnership with our stakeholders

The purpose of today’s session is to discuss all these issues and more. Our aim is clear: to enable a successful energy transition.

At Drax we stand ready to invest hundreds of millions of pounds to scale up BECCS technology;

To put the UK at the forefront of global efforts to reach net zero emissions;

And to help create tens of thousands of green jobs in the North of England.

But I want your help in making BECCS as sustainable and successful as it can be.

We know and can demonstrate how demand for biomass can support healthy forests.

Thank you very much for listening and I wish you a good and constructive session tackling this critical global challenge.
