Building a sustainable business

Will Gardiner, Chief Executive Officer, Drax Group

Opinion

The UK energy sector is changing rapidly. The boundaries between users, suppliers and generators are blurring as energy users are choosing to generate their own energy and are managing their energy use more proactively while, conversely, generators are increasingly seeing users as potential sources of generation and providers of demand management.

“The UK is undergoing an unprecedented energy revolution with electricity at its heart – a transition to a low-carbon society requiring new energy solutions for power generation, heating, transport and the wider economy”

In that context, our Group’s purpose is to help change the way energy is generated, supplied and used for a better future. This means that sustainability, in its broadest sense, must be at the very core of what we do. Successful delivery of our purpose depends on all our people, across all our businesses, doing the right thing, every day. With the right products and services, we can go even further and help our customers make the right, sustainable energy choices.

As our businesses transform and we embrace a larger customer base, different generation technologies and operate internationally, the range of sustainability issues we face is widening and becoming more complex. At the same time, the range of stakeholders looking to Drax for responsible leadership on sustainability is increasing. The need for transparency is greater than ever, so our website’s sustainability section provides a comprehensive insight into the Group’s environmental, social and governance management and performance during 2017.

Some of the highlights include:

  • Carbon reduction: I am pleased that, in 2017, the proportion of our energy generation from renewable sources remained high. 65% of our generation during the year came from sustainable biomass and accounted for 15% of the country’s overall renewable generation. We maintained our rigorous and robust approach to ensure that we only ever use biomass that is sustainably produced and legally sourced.
  • People: Another key achievement was the roll out of our people strategy to 2020 – One Drax – which focuses on talent to deliver on our strategic and operational objectives.
  • Safety: The health and safety of all our employees and contractors is of paramount importance to Drax. While the Group’s safety incident rate remained on target in 2017, the fire at our biomass rail unloading facilities in December did cause an outage, with disruption lasting into 2018. It highlighted once again that the risks of generating using biomass must be mitigated through robust safety procedures and a risk-based plant investment and maintenance programme. Safety therefore remains at the centre of our operational philosophy and we are determined to do even better.
  • Customers: Our business to business (B2B) Energy Supply business received recognition for their dedication to customer service. Opus Energy won “Utilities Provider of the Year” at the British Small Business Awards 2017.

We initiated a process which would allow us to participate in the United Nations Global Compact (UNGC). We are committed to the initiative and its ten principles, which align with our culture of doing the right thing.

Our website’s sustainability section also sets out our commitment to achieving the United Nations’ Sustainable Development Goals through our operations, the services we deliver to our customers and in partnership with others.

Global ambitions and goals are important, but so too are our ambitions for our local and regional communities. As such, we have played a key role in the UK Northern Powerhouse Partnership, initiatives such as POWERful Women and a comprehensive programme of stakeholder engagement.

“Sustainability, in its broadest sense, must be at the very core of what we do”

Finally, I do not believe any organisation, however well intentioned, can get its commitment to sustainability perfect on its own and I am very keen for Drax to learn from people reading our website’s sustainability section. It sets out what we see as our achievements and aspects in which we believe we need to do better. I would like to invite any stakeholder with an interest to comment on what we’re doing and help us improve where we can. Feedback can be submitted at Contact us or via our Twitter account or Facebook page.

Drax Biomass invests in greenhouse gas efficiencies

Sustainable bioenergy
close-up of truck raising and lowering

We have increased the capacity at Drax Biomass Amite and Morehouse pellet plants to increase capacity and made them more greenhouse gas (GHG) efficient. Central to the projects was the addition of storage silos and handling equipment to allow increased use of dry shavings and other mill residuals. The developments included the addition of an extra truck dump at each facility to allow delivery of increased volumes of these feedstocks.

Drax biomass pellet trucks

Use of mill residuals and dry shavings reduces the energy required to make a pellet, as such material does not need to be de-barked, chipped and re-sized in the same way as roundwood. Some of the material has a low moisture content and is therefore able to enter the process after the dryer, which effectively increases the capacity of each plant. This drives down the average GHG emission per tonne of pellets produced. A key measure of this is the KWh of electricity per tonne of pellets, and we saw this reduce by about 10% in the final months of the year compared with the start of the year, with further savings anticipated.

LaSalle BioEnergy in Louisiana

At LaSalle, a significant amount of our investment is going into allowing pellets to be transported to the port by rail, rather than truck. For the 250 km trip to Baton Rouge, a significant carbon saving compared to trucks will be achieved when LaSalle reaches its capacity of 450,000 tonnes per year. Moving pellets by rail should start in the next year.

Active management of forests increases growth and carbon storage

28 July 2017

Sustainable bioenergy

A study on the historical trends in the forest industry of the US South, carried out by supply chain consultancy Forest2Market, and commissioned by Drax Group, the National Alliance of Forest Owners and the U.S. Endowment for Forestry and Communities, found that over the last 60 years, as demand for forestry products has increased, the productivity of the area’s forests has increased too. In short, the more we’ve come to use them, the more forests have grown.

A forest is not like a mine – there is not a finite amount of wood in the ground that disappears when it is extracted, never to return. Forests are a renewable resource that can be replanted, improved, and harvested for as long as the land is managed responsibly.

What’s more, landowners have a strong financial incentive to not only maintain their holdings but to improve their productivity – after all, the more of something you have, the more of it you have to sell. It is an economic incentive that works.

Six decades of growth

The Forest2Market report found that increased demand for wood is statistically correlated with more annual tree growth, more wood volume available in the forest, and more timberland.

For example, between 1953 and 2015, tree harvests increased by 57%, largely driven by US economic growth and increased construction. Over the same period, annual wood growth increased by 112%, and inventory increased by 108%. In total, annual growth exceeded annual removals by 38% on average.

Annual forest growth in the US South increased from 193 million cubic metres in 1953 to 408 million cubic metres in 2015. Inventory increased from 4 billion to 8.4 billion cubic metres.

The forest products industry funded private-public research projects to enhance the quality and performance of seedlings and forest management practices to ensure a stable supply of wood. Because of these efforts, landowners saw the value of active management techniques, changing their approach to site preparation, fertilization, weed control, and thinning, and the use of improved planting stock. Healthy demand made it easy for landowners to take a long-term view, investing in more expensive management practices up front for greater returns in the future. And the results were extraordinary: seedlings established in the last 20 years have helped plantations to become nearly four times as productive as they were 50 years ago.

A changing market

Markets for wood have changed over the last two decades, precipitated by decreased demand for writing paper and newsprint, increased demand for absorbent hygiene products and containerboard and increased demand for biomass. These changes in demand have not impacted the way that landowners manage timberland, however. As sawtimber (the largest trees in the forest) remains the most valuable timber crop, it also remains the crop the landowners want to grow. Pulpwood is harvested from the forest only when the forest is being thinned to create optimal conditions for growing sawtimber or when sawtimber is harvested and the forest is being cleared for replanting.

Pellet production has expanded rapidly in the US South, though its overall footprint is still small in comparison to more traditional forest product industries.

In some local wood basins, however, like the one surrounding Bastrop, Louisiana (the location of one of Drax’s US production facilities), the use of biomass to create pellets has filled a gap left by the closure of an 80-year old paper mill. Drax’s decision to locate in this area is integral to supporting forest industry jobs and landowners who carefully consider local demand when deciding whether to continue growing trees.

According to Tracy Leslie, Director of Forest2Market’s biomaterials and sustainability practice, “As history has shown, forests in the US South have benefitted from increased demand for all types of wood. The rise of the pulp and paper industry did not detract from landowner objectives to maximize production of higher value sawtimber nor did it result in a shift in focus to growing only pulpwood. This new demand did, however, provide landowners with important interim and supplemental sources of income. Forest2Market’s research shows that an increase in demand for pellets will have the same effect, incentivizing landowners to grow and re-grow forests, increasing both forest inventory and carbon storage.”

The real threat to forests

Not only does demand for forest products increase the productivity and carbon storage of forests and provide an incentive for landowners to continue growing trees, but it also helps counter factors that irrevocably destroy this natural resource. The real threat to forests in the US is not demand for wood, but urbanisation. Nearly half of all US forestland that converted to another use between 1982 and 2012 was cleared for urban development.

Commercial forestry protects forested lands from development; between 1989 and 1999, just 1% of managed pine plantations in the US South were cleared for non-forest development compared to 3% of naturally-regenerated forest types.

Urbanisation, not the forest products industry, places the most pressure on forests in the US South. Forest2Market’s findings demonstrate that demand associated with healthy timber markets promotes the productivity of forests and mitigates forest loss by encouraging landowners to continue to grow, harvest, and regenerate trees.

What’s next for bioenergy?

11 July 2017

Sustainable bioenergy
Morehouse BioEnergy in Louisiana

Discussions about our future are closely entwined with those of our power. Today, when we talk about electricity, we talk about climate change, about new fuels and about the sustainability of new technologies. They’re all inexplicably linked, and all hold uncertainties for the future.

But in preparing for what’s to come, it helps to have an idea of what may be waiting for us. Researchers at universities across the UK, including the University of Manchester and Imperial College London, have put their heads together to think about this question, and together with the Supergen Bioenergy programme they’ve created a unique graphic novel on bioenergy that outlines three potential future scenarios.

Based on their imagined views of the future there’s plenty to be optimistic about, but it could just as easily go south.

Future one: Failure to act on climate change

Dams on river

In the first scenario, our energy use and reliance on non-renewable fuels like oil, coal and gas continues to grow until we miss our window of opportunity to invest in renewable technology and infrastructure while it’s affordable.

Neither the beginning nor the end of the supply chain divert from their current trends – energy providers produce electricity and end users consume it as they always have. Governments continue to pursue growth at all costs and industrial users make no efforts to reverse their own rates of power consumption. In response, electricity generation with fossil fuels ramps up, which leads to several problems.

Attempts to secure a dwindling stock of non-renewable fuels lead to clashes over remaining sources as nations vie for energy security. As resources run out, attempts to put in place renewable alternatives are hampered by a lack of development and investment in the intervening years. The damages caused by climate change accelerate and at the same time, mobility for most people drops as fuel becomes more expensive.

Future two: Growing a stable, centralised bioenergy

Rows of saplings ready for planting

A future of dwindling resources and increasing tension isn’t the only way forward. Bioenergy is likely to play a prominent role in the energy mix of the future. In fact, nearly all scenarios where global temperature rise remains within the two degrees Celsius margin (recommended by the Paris Agreement) rely on widespread bioenergy use with carbon capture and storage (BECCS). But how far could the implementation of bioenergy go?

A second scenario sees governments around the world invest significantly in biomass energy systems which then become major, centralised features in global energy networks. This limits the effects of a warming climate, particularly as CCS technology matures and more carbon can be sequestered safely underground.

This has knock-on effects for the rest of the world. Large tracts of land are turned over to forestry to support the need for biomass, creating new jobs for those involved in managing the working forests. In industry, large-scale CCS systems are installed at sizeable factories and manufacturing plants to limit emissions even further.

Future 3: The right mix bioenergy

Modern house with wind turbine

A third scenario takes a combined approach – one in which technology jumps ahead and consumption is controlled. Instead of relying on a few concentrated hubs of BECCS energy, renewables and bioenergy are woven more intimately around our everyday lives. This relies on the advance of a few key technologies.

Widespread adoption of advanced battery technology sees wind and solar implemented at scale, providing the main source of electricity for cities and other large communities. These communities are also responsible for generating biomass fuel from domestic waste products, which includes wood offcuts from timber that makes up a larger proportion of building materials as wooden buildings grow more common.

Whether future three – or any of the above scenarios – will unfold like this is uncertain. These are just three possible futures from an infinite range of scenarios, but they demonstrate just how wide the range of futures is. It’s up to us all – not just governments but businesses, individuals and academics such as those behind this research project too – to to make the best choices to ensure the future we want.

This is how you unload a wood chip truck

30 June 2017

Sustainable bioenergy
Truck raising and lowering

A truck arrives at an industrial facility deep in the expanding forestland of the south-eastern USA. It passes through a set of gates, over a massive scale, then onto a metal platform.

The driver steps out and pushes a button on a nearby console. Slowly, the platform beneath the truck tilts and rises. As it does, the truck’s cargo empties into a large container behind it. Two minutes later it’s empty.

This is how you unload a wood fuel truck at Drax Biomass’ compressed wood pellet plants in Louisiana and Mississippi.

What is a tipper?

“Some people call them truck dumpers, but it depends on who you talk to,” says Jim Stemple, Senior Director of Procurement at Drax Biomass. “We just call it the tipper.” Regardless of what it’s called, what the tipper does is easy to explain: it lifts trucks and uses the power of gravity to empty them quickly and efficiently.

The sight of a truck being lifted into the air might be a rare one across the Atlantic, however at industrial facilities in the United States it’s more common. “Tippers are used to unload trucks carrying cargo such as corn, grain, and gravel,” Stemple explains. “Basically anything that can be unloaded just by tipping.”

Both of Drax Biomass’ two operational pellet facilities (a third is currently idle while being upgraded) use tippers to unload the daily deliveries of bark – known in the forestry industry as hog fuel, which is used to heat the plants’ wood chip dryers – sawdust and raw wood chips, which are used to make the compressed wood pellets.

close-up of truck raising and lowering

How does it work?

The tipper uses hydraulic pistons to lift the truck platform at one end while the truck itself rests against a reinforced barrier at the other. To ensure safety, each vehicle must be reinforced at the very end (where the load is emptying from) so they can hold the weight of the truck above it as it tips.

Each tipper can lift up to 60 tonnes and can accommodate vehicles over 50 feet long. Once tipped far enough (each platform tips to a roughly 60-degree angle), the renewable fuel begins to unload and a diverter guides it to one of two places depending on what it will be used for.

“One way takes it to the chip and sawdust piles – which then goes through the pelleting process of the hammer mills, the dryer and the pellet mill,” says Stemple. “The other way takes it to the fuel pile, which goes to the furnace.”

The furnace heats the dryer which ensures wood chips have a moisture level between 11.5% and 12% before they go through the pelleting process.

“If everything goes right you can tip four to five trucks an hour,” says Stemple. From full and tipping to empty and exiting takes only a few minutes before the trucks are on the road to pick up another load.

Efficiency benefits

Using the power of gravity to unload a truck might seem a rudimentary approach, but it’s also an efficient one. Firstly, there’s the speed it allows. Multiple trucks can arrive and unload every hour. And because cargo is delivered straight into the system, there’s no time lost between unloading the wood from truck to container to system.

Secondly, for the truck owners, the benefits are they don’t need to carry out costly hydraulic maintenance on their trucks. Instead, it’s just the tipper – one piece of equipment – which is maintained to keep operations on track.

However, there is one thing drivers need to be wary of: what they leave in their driver cabins. Open coffee cups, food containers – anything not firmly secured – all quickly become potential hazards once the tipper comes into play.

“I guess leaving something like that in the cab only happens once,” Stemple says. “The first time a trucker has to clean out a mess from his cab is probably the last time.”

3 ways decarbonisation could change the world

27 June 2017

Sustainable business

Mitigating climate change is a difficult challenge. But it’s one well within the grasp of governments, companies and individuals around the world if we can start thinking strategically.

On the behalf of the German government, The Internal Energy Agency (IEA) and the International Renewable Energy Agency (IRENA) have jointly published a report outlining the long-term targets of a worldwide decarbonisation process, and how those targets can be achieved through long-term investment and policy strategies.

At the heart of the report is a commitment to the ‘66% two degrees Celsius scenario’, which the report defines as, ‘limiting the rise in global mean temperature to two degrees Celsius by 2100 with a probability of 66%’. This is in line with the Paris Agreement, which agreed on limiting global average temperature increase to below two degrees Celsius.

Here are three of the findings from the report that highlight how decarbonisation could change the world.

The energy landscape will change – and that’s a good thing

Decarbonisation will by definition mean reducing the use of carbon-intensive fossil fuels. Today, 81% of the world’s power is generated by fossil fuels. But by 2050, that will need to come down to 39% to meet the 66% two degrees Celsius scenario, according to the report. But, this doesn’t mean all fossil fuels will be treated equally.

Coal will be the most extensively reduced, while other fossil fuels will be less affected. Oil use in 2050 is expected to stand at 45% of today’s levels, but will likely still feature in the energy landscape due its use in industries like petrochemicals.

Gas will likely also remain a key part of the energy makeup, thanks to its ability to provide auxiliary grid functions like frequency response and black-starting in the event of grid failure.

Renewables like biomass will likely play an increasing role here as well, particularly when combined with carbon capture and storage (CCS) technology.

Overall, renewable energy sources will need to increase substantially. In the report’s global roadmap for the future, renewables make up two thirds of the primary energy supply. Reaching this figure will be no mean feat – it will mean renewable growth rates doubling compared with today.

Everyday electricity use will become more efficient 

The report highlights the need for ‘end-use’ behaviour to change. This can mean everyday energy users choosing to use a bit less heat, power and fuel for transport in our day-to-day activities, but a bigger driver of change will be by investment in better, more efficient end-use technology – the technology, devices and household appliances we use every day.

In fact, the study argues that net investment in energy supply doesn’t need to increase beyond today’s level – what needs to increase is investment in these technologies. For instance, by 2050, 70% of new cars must be electric cars to meet decarbonisation targets.

Infrastructure design could also be improved for energy efficiency – smart grids, battery storage and buildings retrofitted with energy efficient features such as LED lighting will be essential. There’s also the possibility of increased use of cleaner building materials and processes – for example, constructing large scale buildings out of wood rather than carbon-intensive materials such as concrete and steel.

Decarbonisation will cost, but not decarbonising will cost more

The upfront costs of meeting temperature targets will be substantial. A case study used in the report estimates that $119 trillion would need to be spent on low-carbon technologies between 2015 and 2050. But it also suggests another $29 trillion may be needed to meet targets.

However, failure to act could mean the world will pay out an even higher figure in healthcare costs, or in other economic costs associated with climate change, such as flood damage or drought. Therefore, the sum for decarbonisation could end up costing between two and six times less than what failing to decarbonise could cost.

On top of this, the new jobs (including those in renewable fuel industries that will replace those lost in fossil fuels) and opportunities that will be created between 2015 and 2050 could add $19 trillion to the global economy. More than that, global GDP could be increased by 0.8% in 2050, thanks to added stimulus from the low carbon economy.

Achieving a cleaner future won’t be easy – it requires planning, effort, and the will to see beyond short-term goals and think about the long-term benefits. But as the report demonstrates, get it right and the results could be considerable.

How sustainable biomass crosses the Atlantic to power the nation

21 June 2017

Sustainable bioenergy

In the UK, we’re so accustomed to using electricity we rarely think of the journey it takes from power station to plug.

In fact, electricity must travel across a network of cables, wires and substations before it makes it from the power stations generating it to the homes and businesses using it. At Drax Power Station, which supplies 16% of Great Britain’s renewable power, there’s another journey that takes place even before the electricity leaves the power station.

This journey – the journey of more than half of the compressed wood pellet fuel Drax uses to generate electricity – has its origins in the expanse of forestland in the southern USA.

From forest to fuel

The journey starts in the huge, working forests of the southern states of the USA where low value wood – such as the thinnings cleared as part of a forests’ growing cycle – is collected in a responsible and sustainable way to make high density wood pellets, which Drax Power Station uses to produce more than 60% of its electricity.

Drax Group’s own pellet manufacturer, Drax Biomass, produces around 15% of the power station’s renewable fuel. After pelletisation locally at its Amite and Morehouse facilities, located in Louisiana and Mississippi respectively, the biomass is transported to Drax Transit at the Port of Greater Baton Rouge, on the Mississippi River. From Morehouse, trains made up of closed-top grain cars, each capable of carrying 120 tonnes, transport the pellets 221 miles to Baton Rouge. At Amite, just 60 miles from Baton Rouge, fuel-efficient trucks carry 25-tonne loads between plant and port.

Once at the port, the truck and train cargoes are unloaded into one of two biomass storage domes – each holding 40,000 tonnes of biomass – before being loaded into the ships for their transatlantic journey.

A boat arrives at Peel Ports in Liverpool

From port to port

Drax uses a range of ships to carry the pellets on their 8,000-mile journey to the UK, ranging from big ‘Coastal’ ships, capable of hauling 20,000 tonnes, to truly massive Panamax ships, more than a quarter of a kilometre in length and capable of carrying up to 80,000 tonnes.

The ships leave the port and spend 24 hours travelling the 200 miles down the Mississippi River into the Gulf of Mexico, around Florida, and into the Atlantic. From here, it’s a 19-day voyage to reach ports in the UK. To put that into perspective, it took Columbus more than two months to make his first trip across the Atlantic.

The ships pull into ports in Tyne, Hull, Immingham and Liverpool, where they are unloaded. At the bespoke biomass port facility at Peel Ports in Liverpool an Archimedean screw removes the pellets from the ship’s holds and transports them onto a conveyer belt, which loads them onto trains. These four ports can process up to 12 million tonnes of biomass every year, combined.

From port to power station

Like the stateside journey, Drax uses trains to carry its cargo from port to power plant. The difference on the UK side, however, is that the UK trains were designed specifically to carry biomass wood pellets. Clever design and engineering was used to maximise the space inside each carriage and ensure the trains carry large loads despite UK rail restrictions.

These trains carry the pellets across the country (and even over the Pennines for trains coming from Liverpool) to Drax Power Station in Selby, North Yorkshire. Roughly 14 trains arrive at the plant every day and collectively unload about 20,000 tonnes of pellets every day, from Monday to Saturday. A system of conveyor belts carry these pellets to one of Drax’s four giant biomass storage domes, each capable of housing about 80,000 tonnes of pellets.

Then, when needed, the conveyor system takes the pellets on their final journey: into the furnace. The pellets are combusted, which boils water to create steam, which turns a turbine connected to a generator, which then feeds electricity to the national grid. The electricity travels across miles of cables, and wires, through substations and transformers, and finally into your power socket.

Long journey, low emissions

Despite the number of miles travelled, the journey of biomass is tracked and managed to ensure the Drax Power Station supply chain is as low-carbon as possible. The result is that, even with all supply chain emissions considered, the power generated has a carbon emissions profile that is more than 80% lower than coal.

It might be one of the most impressive supply chains involved in powering this island – but it’s not the only one to travel thousands of miles. The journey of biomass to England joins liquefied natural gas (LNG) shipped from the Middle East, coal from Colombia and solar panels manufactured in China – imports that ensure we have readily available access to power on our shores.
