[Carbon Capture Magazine article] Spiking Energy Demand

7 May 2024

Opinion

This story first appeared in Carbon Capture Magazine.

By Raj Swaminathan, Senior Vice President at Drax.

While there’s little debate that the greenhouse gas emissions that sit at the heart of our planet’s unprecedented warming come from fossil fuel consumption and other human activities, clawing back these carbon outputs is a multi-faceted issue. In addition to efforts to transition to renewable power sources like wind, solar, and biomass, which remain essential to mitigating this crisis, leading scientists agree that reducing emissions is not sufficient; we must go further and faster with carbon removals.

It’s estimated that we’ll need to capture and store as much as 9.5 billion metric tons of CO2 every year by 2050 to reverse legacy emissions enough to achieve international climate targets, according to the IPCC. Today, carbon removal facilities only capture a fraction of the emissions generated across the planet, and we urgently need a spectrum of high-quality solutions to scale our ability to remove carbon from the atmosphere.

At the same time, spiking energy demand – driven largely by the growing needs of data centers, particularly those underpinning artificial intelligence (AI) and blockchain technology, as well as new industrial and manufacturing facilities – also means we need to increase generation capacity rapidly to avoid an energy security crisis. This becomes more difficult to achieve through intermittent sources like wind and solar alone, which can’t be turned up and down when the grid is strained, opening an opportunity for solutions that can provide renewable, baseload power while permanently removing carbon from the atmosphere to fill this vital need.

Bioenergy with CCS – a critical technology for decarbonization

Bioenergy with carbon capture and storage (BECCS) is a carbon removal technology that uses sustainably sourced biomass to generate renewable energy while permanently sequestering the carbon underground. Because BECCS is one of the only renewable sources that can generate baseload power around the clock, seven days a week, it can serve as the backbone of renewable power grids for when the sun isn’t shining, or the wind isn’t blowing – a role fossil fuels often fill today.

At the same time, BECCS captures post-combustion carbon at the stack and pipelines it into geologic storage, permanently securing it underground. These high-quality carbon removals are more straightforward to measure in comparison with other solutions like nature-based removals, making it much simpler to quantify the overall impact achieved.

Compared to other carbon capture technologies, BECCS also has more diversified revenue streams – including renewable power generation, government incentives for carbon storage, and the sale of carbon dioxide removals (CDR) credits to offset emissions for other companies and industries. Because of this diversification, BECCS not only provides a clearer path to profitability but also offers a high-quality CDR at a much lower price point than alternatives like direct air capture (DAC). This results in a more sustainable and scalable path to adoption.

Due to these advantages, BECCS is positioned to do much of the heavy lifting regarding carbon removals, but it doesn’t replace the need for additional carbon capture and renewable energy solutions. Technologies like DAC, while costlier to operate today, will play an important role in helping to reverse legacy emissions as well; in fact, BECCS could even power DAC facilities to ensure they’re running on renewable energy. The same is true for renewable power technologies – we need far more wind and solar capacity in addition to BECCS.

Pioneering BECCS in the US and UK

Drax believes that BECCS will be integral to decarbonizing the power sector and hard-to-abate industries. To this end, Drax has launched a new independent business unit this year that is focused on becoming the global leader in large-scale carbon removals. This business unit will oversee the development and construction of Drax’s new-build BECCS plants in the US and internationally, and it will work with a coalition of strategic partners to focus on an ambitious goal of removing at least 6 Mt of CO2 per year from the atmosphere.

Previously, Drax successfully completed two BECCS pilots at Drax Power Station, the UK’s largest power station that contributes approximately 4 percent of Britain’s generation output and 11 percent of its renewables. The Drax team is now working to outfit Drax Power Station with BECCS technology that will remove an estimated 8 Mtpa of carbon while generating 10 TWh of power. This is slated to be the first carbon-negative power station in the world and is key to achieving Drax’s goal of becoming a carbon-negative company.
Drax is also pursuing an initial target in the U.S. to have two BECCS plants built and operating by the 2030s. These will be the first large-scale, biomass-fueled power stations in North America, generating an estimated total of 4 Twh of power while sequestering approximately 6 Mt of CO2 per year.

BECCS is an essential technology to help achieve global decarbonization targets. While it doesn’t replace the need for additional carbon capture and renewable power generation alternatives, its unique advantages can help reverse carbon pollution from the past while meeting the energy demands of the future.

Biomass and BECCS are essential in the UK’s journey to Net Zero

10 August 2023

Opinion

The Strategy provides an important steer on the short-, medium- and long-term use of biomass in the UK’s 2050 Net Zero target.

With the Government’s Strategy in hand, I am more certain than ever on two things.  First, that there remains a clear and powerful role for biomass and BECCS in helping the UK balance harder to abate sectors, like aviation, and reach Net Zero.

And secondly, that bioenergy with carbon capture and storage (BECCS) has a vital role to play in our global energy transition – and that Drax is well placed to deliver.

Why we should be confident

In developing the Strategy, the Government has considered several factors including: availability of biomass and the priorities for end use; impacts on air quality; the sustainability of biomass use; as well as the role of BECCS in helping to reach our long-term climate goals.

The ‘Priority Use Framework’ evaluates where biomass would be most sustainably and efficiently used across sectors, given supply constraints. This framework is an important tool, which has been developed with four key principles in mind; sustainability; air quality; the circular economy and resource efficiency; and ability to support us getting to Net Zero.

Critically, the Priority Use Framework states that:

  1. In the short-term (2020s) government will continue to facilitate sustainable biomass deployment through a range of incentives and requirements covering power, heat and transport
  2. In the medium-term (to 2035) government intends to further develop biomass use for utilities such as heat and power with a view to where possible transition to BECCS
  3. Biomass for use in BECCS should be prioritised in the long term (to 2050)

It’s very encouraging to see Government recognise the important role that biomass plays in our energy transition in both the short and medium term, as well as its prioritisation of BECCS in the long term.

Although there are various routes for deploying BECCS across different industries, the strategy further prioritises the deployment of BECCS on existing biomass generation plants with established supply chains, further supported by the development of the Power-BECCS business model for the first BECCS projects.

The Strategy is also promising as it presents an evidence-driven basis for long-term policy stability and I believe if the Government continues in this direction, it will draw investment to the UK’s bioenergy industry.

Why this is critical for the country

Biomass has already played an important role in supporting energy security while helping the UK decarbonise, displacing fossil fuels with a source of renewable, dispatchable power. Our work has also made a significant contribution to the UK economy, adding an estimated £1.8 billion to the UK GDP and supporting 17,800 jobs in 2021 alone.

And, looking to the future, BECCS presents an enormous opportunity to the UK.

Early investment in this critical technology has the potential to support energy security, and climate targets whilst creating jobs and making the UK a leader in the potentially trillion-dollar global CDR market.

This work needs to happen now – nearly all realistic pathways to limit warming to 1.5C require the carbon removal technology and renewable power BECCS offers, and expert voices at the UN’s Intergovernmental Panel on Climate Change, the UK’s Climate Change Committee, and Forum for the Future have said that carbon removals will be needed to address the climate crisis.

Today’s Strategy is a clear signal from Government that they recognise the importance of BECCS and the urgency with which we must employ it within the UK.

Why this is encouraging for Drax

Drax is an international, growing, sustainable business at the heart of global efforts to deliver Net Zero and energy security and I believe the Strategy we have seen from Government today is a clear indication of their support for the work that we do.

With BECCS, Drax has the ability to become a global leader in carbon removals technology. We are engaged in formal discussions with the UK Government about the project and, providing these are successful, we plan to invest billions in transforming Drax Power Station into the world’s largest carbon removals project. The prioritisation of BECCS within the Priority Use Framework shows the Government is aligned to this vision.

As we look forward

We welcome the Government’s Biomass Strategy and will continue to unpack what it means for our business over the coming days and weeks with a mind to our next steps.

Government must now ensure that as it progresses its consultation on biomass sustainability that that process is equally evidence-driven and ensures that science-based methods drive the policy forward. We hope to continue to work alongside Government to support these efforts.

Our formal discussions with the UK Government on BECCS and a ‘bridging mechanism’ to support the transition to BECCS have been productive, but to realise the scale of the ambition included in the Government’s Strategy, we need commitment through the delivery of a clear business model that supports BECCS.

Today’s support from Government brings us a big step closer and we look forward to continuing the work.

UK Biomass Strategy – Highly Supportive of Biomass and a Priority Role for BECCS

Financial News

The Strategy outlines the potential extraordinary role which biomass can play across the economy in power, heating and transport, including a priority role for Bioenergy Carbon Capture and Storage (BECCS), which is seen as critical for meeting net zero plans due to its ability to provide large-scale carbon removals.

Will Gardiner, Drax CEO, said:

Will Gardiner, Drax Group CEO

“We welcome the UK Government’s clear support for sustainably sourced biomass and the critical role that BECCS can play in achieving the country’s climate goals.

“The inclusion of BECCS at the top of a priority use framework is a clear signal that the UK wants to be a leader in carbon removals and Drax is ready to deliver on this ambition. We are engaged in formal discussions with the UK Government about the project and, providing these are successful, we plan to invest billions in delivering BECCS at Drax Power Station in North Yorkshire, simultaneously providing reliable, renewable power and carbon removals.

“We look forward to working alongside the Government to ensure biomass is best used to contribute to net zero across the economy, through further progression of plans for BECCS and ensuring an evidence-driven, best practice approach to sustainability.”

A priority role for BECCS

The Strategy reiterates the Government’s ambition to deliver 5Mt pa of carbon removals by 2030, with the potential for this to increase to 23Mt by 2035 and up to 81Mt by 2050, with BECCS expected to provide the majority of the total in 2050.

In the period to 2035 Government intends to facilitate the use of biomass for power and heating, whilst supporting projects transitioning to BECCS. BECCS projects, which includes Drax Power Station, are seen as a priority use of biomass given existing generation assets with established supply chains and Carbon Capture and Storage (CCS) technology ready to be deployed. Beyond 2035 there will remain a role for biomass without BECCS in harder to decarbonise sectors and in supporting energy security.

The Strategy notes the active work in government to support BECCS, including the development of business models.

Biomass availability and sustainability

The Strategy considers the global availability of sustainable biomass, finding that by using domestic and imported biomass sources there is sufficient material to meet estimated future demand in the 6th Carbon Budget.

Alongside the increased use of sustainable biomass, Government will continue to develop sustainability criteria and Drax supports the development of robust standards across sectors.

A link to the Strategy can be found here.

Scientific assessment of carbon removals from BECCS

Alongside publication of the Strategy, the Government has published an evidence-based assessment of BECCS as a route to negative emissions. The report sets out how “well regulated” BECCS can deliver negative emissions and ensure positive outcomes for people, the environment, and the climate.

BECCS at Drax Power Station

In March 2023, the Government confirmed its commitment to support the deployment of large-scale Power-BECCS projects by 2030 and that the Drax Power Station BECCS project had passed the deliverability assessment for the Power-BECCS project submission process.

Formal bilateral discussions with the Government are ongoing to move the project forward and help realise the Government’s ambition to deliver 5Mt pa of carbon removals by 2030. These discussions include a bridging mechanism between the end of the current renewable schemes in 2027 and the commissioning of BECCS at Drax Power Station.

Drax believes that BECCS at Drax Power Station is the only project in the UK that can enable the Government to achieve this ambition, in addition to the large-scale renewable power and system support services it provides to the UK power system.

In July 2023, the Government designated the Viking CCS cluster as a Track 2 cluster. Progressing a CO2 transport and storage network in the Humber represents a significant step toward helping the region meet its net zero ambitions and ensuring that it remains a source of high-skilled jobs and energy security for decades to come. Along with the East Coast Cluster, Viking creates an additional potential pathway to support BECCS at Drax Power Station.

The Government has also confirmed that during 2023 it will set out a process for the expansion of its wider CCS programme for individual projects, including BECCS (Track 1 expansion and Track 2).

Carbon markets will be essential in reaching net zero – we must ensure they support high standards

9 November 2022

Carbon capture

Angela Hepworth, Commercial Director, Drax

In brief:

  • The voluntary carbon market will be essential in deploying engineered carbon removals technologies like Bioenergy with carbon capture and storage (BECCS), and direct air carbon capture and storage (DACS) at scale.
  • The Integrity Council for the Voluntary Carbon Market is developing a set of Core Carbon Principles (CCPs).
  • Drax support proposed principles if they’re applied in ways appropriate for engineered carbon removals.
  • Standards around additionality and the permanence of carbon removals may apply very differently to nature-based and engineered removals, something that needs to be addressed explicitly.

There’s growing recognition, in governments and environmental organisations, of the urgent need to develop high-integrity engineered carbon removals at scale if the world has any chance of meeting our collective Paris-aligned climate goals.

Bioenergy with carbon capture and storage (BECCS), and direct air carbon capture and storage (DACS) are two technologies on the cusp of deployment at scale that can remove carbon from the atmosphere and store it permanently and safely. The technology is proven, developers are bringing forward projects, and the most forward-thinking companies are actively seeking to buy removal credits from BECCS and DACS developers.

Yet there’s a risk that the frameworks being developed in the voluntary carbon market could stifle rather than support the development of engineered carbon removals.

Drax is a world-leader in the deployment of bioenergy solutions. Our goal is to produce 12 million tonnes of high-integrity, permanent CO2 removals by 2030 from its BECCS projects in the U.K. and the U.S. We support the development of rigorous standards for CO2 removals that give purchasers confidence in the integrity of the CO2 removals they’re buying. Such standards are also important in providing a clear framework for project developers to work to.

However, the market and its standards have largely developed around carbon reduction and avoidance credits, rather than removals. To create a market that can enable engineered carbon removals at scale, re-thinking is needed to create standards that are fit for purpose to tackle the climate emergency.

Core Carbon Principles

The Integrity Council for the Voluntary Carbon Market is in the process of developing a set of Core Carbon Principles (CCPs) and Assessment Framework (AF) intended to set new threshold standards for high-quality carbon credits.

At Drax, we welcome and support the principles proposed by the Integrity Council. However, it’s crucial they’re applied in ways that are appropriate for engineered carbon removals, and support rather than prevent their development.

Many CCPs are directly applicable to engineered carbon removals and can offer important standards for projects developing removals technologies. Among the most important principles include those stating:

  • Removals must be robustly quantified, with appropriate conservatism in any assumptions made.
  • Key information must be provided in the public domain to enable appropriate scrutiny of the carbon removal activity, while safeguarding commercially sensitive information.
  • Removal credits should be subject to robust, independent third-party validation and verification.
  • Credits should be held in a registry which deals appropriately with removal credits.
  • Registries must be subject to appropriate governance, to ensure their integrity without becoming disproportionately bureaucratic or burdensome.
  • Removals must adhere to high standards of sustainability, taking account of impacts on nature, the climate and society.
  • There should be no double counting of carbon removals between corporates, or between countries. Bearing in mind that both corporates and countries may count the same removals in parallel, and that the Article 6 mechanism means countries can decide whether trades between corporates should or shouldn’t trigger corresponding adjustments to countries’ carbon inventories.

However, as pioneers in the field, we believe that two of the Core Carbon Principles need to be adapted to the specific characteristics of engineered carbon removals.

Supporting additionality and development incentives

The CCPs state: “The greenhouse gas (GHG) emission reductions or removals from the mitigation activity shall be additional, i.e., they would not have occurred in the absence of the incentive created by carbon credit revenues.”

Engineered carbon removal credits such as BECCS and DACS are by their nature additional. They are developed for the specific purpose of removing CO2 from the atmosphere and putting it back in the geosphere. They also rely on revenue from carbon markets – largely the voluntary market at present, but potentially compliance markets such as the U.K. and E.U. ETS in the future.

However, most early projects are likely to have some form of Government support (e.g., 45Q in the U.S., or Contracts for Difference in the U.K.) from outside carbon credit revenues. But that support isn’t intended to be sufficient on its own for their deployment – project developers will be expected to sell credits in compliance or voluntary markets.

Engineered carbon removals have high up-front capital costs, and it’s clear that revenue from voluntary or compliance markets will be essential to make them viable.

Additionality assessments should be risk-based. If it’s clear that a technology-type is additional, a technology-level assessment should be sufficient. This should be supplemented with full transparency on any government support provided to projects.

Compensating against non-permanent storage

On the topic of permanence that CCPs state: “The GHG emission reductions or removals from the mitigation activity shall be permanent, or if they have a risk of reversal, any reversals shall be fully compensated.”  A key benefit of engineered carbon removals with geological storage is that they effectively provide permanent carbon removal. Any risk of reversal over tens of thousands of years is extremely small.

The risk of reversal for nature-based credits, by contrast, is much greater. Schemes for managing reversal risk in the voluntary carbon market that have been developed for nature-based credits, are not necessarily appropriate for engineered removals.

Requirements for project developers to set aside a significant proportion of credits generated in a buffer pool, potentially as much as 10%, are disproportionate to the real risk of reversal from a well-manged geological store. They also fail to take account of the stringent regulatory requirements for geological storage that already exist or are being put in place.

Any ongoing requirements for monitoring should be consistent with existing regulatory requirements placed on storage owners and operators. Similarly, where jurisdictions have robust regulatory arrangements for dealing with CO2 storage risk, which place liabilities on storage owners, operators, or governments, the arrangements in the voluntary carbon market should mirror these arrangements rather than cutting across them, and no additional liabilities should be put on project developers.

At Drax, we believe the CCPs provide a suitable framework to ensure the integrity of engineered carbon removals. If applied pragmatically, they can give purchasers of engineered carbon removal credits confidence in the integrity of the product they’re buying and provide a clear framework for project developers. They can ensure that standards support, rather than stifle the development of high integrity carbon removal projects such as BECCS and DACS, which are essential to achieving our global climate goals.

Carbon removals is a global need. The U.S. is making it possible

Will Gardiner, Chief Executive Officer, Drax Group

20 October 2022

Carbon capture

Key takeaways:

  • Removing carbon from the atmosphere is urgent if we are to meet global climate targets
  • The U.S.’s commitment to supporting carbon removal technologies creates an opportunity for new bioenergy with carbon capture and storage (BECCS) power stations
  • The market for carbon credits is gaining increasing credibility and verification, making it a source of financing for ambitious decarbonization projects
  • Carbon markets are needed now to make investment into vital removals projects possible in the U.S. and globally

After a summer of soaring temperatures across the Northern Hemisphere, the global nature of climate change is more obvious than ever. Forest fires around the world in 2021 resulted in double the loss of tree cover than in 2001, while today more than 2.3 billion people face water stress from drought. It’s clear that the action we take to help tackle the global climate emergency must be international too.

We believe that carbon dioxide (CO2) removals will be crucial in addressing this global challenge. Experts and governments agree that in addition to economy-wide decarbonization, removing carbon from the atmosphere is critical to meeting the goal of net zero CO2 emissions by mid-century. The IPCC says 10 billion tons per year of removals will be needed in 2050 for the world to get to net zero. That’s a huge step up from the 40 million tons captured globally in 2021, but also a significant investment opportunity.

Our ambition is to remove 4 million tons of CO2 through bioenergy with carbon capture and storage (BECCS) outside the UK per year, while generating renewable, baseload electricity and supporting healthy, sustainable forests.

The likely contender for our first location? The United States. We already operate in communities across the U.S. South, employing more than 1,200 people in our sustainable biomass pellet production. Now we are preparing to build a new BECCS power station in the region.

It’s clear to us that the U.S. is an ideal market for BECCS with its long-running sustainable forest industry and range of suitable sites for permanent CO2 storage. We see the country’s efforts to retire coal by 2030 and commitment to innovation as an opportunity to build one of the largest carbon removal projects in the U.S. Our first plant could be capable of permanently removing 2 million tons of carbon from the atmosphere a year, while also generating 2-terawatt hours of 24/7 renewable power.

The U.S.’s newly legislated commitment to tackling climate change through the Inflation Reduction Act, as well as the Department of Energy’s National Renewable Energy Lab recent scenario planning for ‘100% clean electricity system’ are establishing it as the leading market to deploy new environmental technologies. And a new frontier for permanent, high-quality emissions removals.

The need for high quality, permanent emissions removals

A net zero future is only possible through the wide-spread implementation of high-integrity, carbon removals. BECCS offers this by combining low carbon, renewable biomass power generation with carbon capture technology and secure, permanent carbon sequestration.

BECCS works by generating renewable electricity using biomass sourced from sustainably managed forests that absorb CO2 as they grow. CO2 released in the generation process is captured and stored, permanently and safely, in geological rock formations. The overall process removes more CO2 from the atmosphere than it emits, resulting in negative emissions.

This allows us to offer decarbonizing industries high-quality carbon removals credits. Given the scale of CO2that must be removed from the atmosphere and the importance for countries and companies around the world to reach net zero, I believe this market for verified CO2 removal credits is a trillion-dollar opportunity.

Voluntary carbon markets have historically suffered from a lack of sustained and reliable investment due to fluctuating market prices and varying quality of the carbon credits they contain. However, increased oversight from investors, NGOs and independent bodies is encouraging credibility and integrity, prompting sustained adoption by businesses.

Will Gardiner, Drax Group CEO

We’ve demonstrated the growing appetite for carbon removals by signing the worlds largest carbon removals deal to date at New York Climate week. The agreement with Respira, an impact-driven carbon finance business, will allow it to purchase 400,000 metric tons of CO2 removals (CDRs) a year from our North American operations. This would enable other corporations and financial institutions to achieve their own CO2 emissions reduction targets, by purchasing CDRs from Respira.

Deals like these make voluntary carbon markets a more effective means of reducing net CO2 emissions by securing commitments and driving investment in projects that deliver independently verified, high-quality emissions reductions. As the global economy works towards its net zero targets, CO2 removals will be crucial in reducing the still dangerously high levels of carbon in our atmosphere today.

BECCS stands to be a powerful tool in a net zero future as the only technology capable of delivering both high quality, permanent carbon removals, while also delivering baseload renewable power. The ability to generate power with negative emissions will be crucial for increasingly electrified economies, as they move away from fossil fuels.

The potential for the U.S.  

Driven by a dynamic mix of markets, investors and engaged consumers, some of the most prominent U.S. companies are pledging to reach net zero, investing in 24/7 renewable power and other means to do so.

Technology companies like Alphabet, Apple, and Microsoft have laid out ambitious plans to decarbonize operations, supply chains, and even remove historic emissions. Other organizations, like the First Movers Coalition, include U.S. companies from a range of sectors committing corporate purchasing power to solving difficult decarbonization challenges.

This industry readiness is increasingly backed up by legislative policy action. The recent Inflation Reduction Act substantially increases the availability of the 45Q tax credit for carbon capture and storage projects, increasing their value from $50 a ton of carbon removals to $85 per ton, helping to further support the business case needed to deploy technologies like BECCS.

We believe the U.S. is on the right track to create a market in which BECCS can thrive. The Department of Energy’s National Renewable Energy Lab recent ‘100% clean electricity system’ report includes BECCS in three of the four possible scenarios explored. It forecasts the US will need between 7-14GW of installed BECCS capacity by 2035 to achieve an electricity system with net zero CO2 emissions. That equates to removals of approximately 55-120 Mt CO2 per year by 2035.

The U.S.’s established forestry commercial industry, with its credible commitment to sustainable management offers ample low-grade wood and wood industry residues to power BECCS. The country’s long-running exploration of CO2 capture and transport, and history of industrial innovations means there are the skills, supply chains, and regulatory environment to undertake ambitious new infrastructure projects.

LaSalle Forest

BECCS is a proven technology and one that can scale up sooner than any other technology. But action is needed now to make these markets that can deliver large scale carbon removals projects a reality.

Action is needed now

For responsible businesses with the desire to go further, faster, or for sectors still developing viable decarbonization routes, carbon removals from BECCS deliver real, verifiable, and permanent progress towards net zero and beyond, to net negative.

It’s encouraging to see the U.S. pass legislation that can facilitate investment into carbon removal technologies and develop the carbon credit market.

However, carbon markets must have standards that are credible both in the business community, and in the environmental and civil society. Collaboration between governments, corporations, and NGOs will be critical to ensure we create systems that can tackle the climate emergency.

We can’t afford to contemplate theoretical net zero futures. Buying and selling high-quality permanent removals is the action we need today. Now is the time to capture the opportunity and be part of the solution together.

Why the Humber represents Britain’s biggest decarbonisation opportunity

5 September 2022

Carbon capture

Richard Gwilliam, Head of Cluster Development at Drax

Key takeaways:

  • The Humber industrial cluster contributes £18 billion a year to the UK economy and supports 360,000 jobs in heavy industry and manufacturing.
  • As demand for industrial products with green credentials rises and net zero targets demand decarbonisation, businesses in the Humber need to begin implementing carbon capture at scale.
  • The size of the Humber and diversity of industries make it a significant challenge but if we get it right, the Humber will be a world leader in decarbonisation.
  • Without investment in decarbonisation infrastructure the region risks losing its status as a world leading industrial cluster putting hundreds of thousands of jobs at risk.

When the iconic Humber Bridge opened in June 1981, it did more than just set records for its size. It connected the region, uniting both communities and industries, and allowing the Humber to become what it is today: a thriving industrial hub that contributes more than £18 billion to the UK economy and supports some 360,000 jobs.

As the UK works towards a low-carbon future, the shift to a green economy will require new regional infrastructure, that once again unites the Humber’s people and businesses around a shared goal.

While the Humber Bridge connected the region across the estuary waters, a new subterranean pipeline that can transport the carbon captured from industries, will unify the region’s decarbonisation efforts.

It’s infrastructure that will be crucial in helping the UK reach its net zero goals, but also cement the Humber’s position as a global decarbonisation leader.

The Humber Bridge

Capturing carbon across the Humber

Capturing carbon, preventing emissions from entering the atmosphere and storing them safely and permanently, is a fundamental part of decarbonising the economy and tackling climate change. Aside from the chemical engineering required to extract carbon dioxide (CO2) from industrial emissions, one of the key challenges of carbon capture is how you transport it at scale to secure storage locations, such as below the North Sea bed where the carbon can be permanently trapped and sequestered.

Engineers at Drax Power Station

At Drax, we’re pioneering bioenergy with carbon capture and storage (BECCS) technology. But carbon capture will play an important role in decarbonising a wide range of industries. The Humber region not only produces about 20% of the UK’s electricity, it’s also a major hub for chemicals, refining, steel making and other carbon-intensive industries.

The consequence of this industrial mix is that the Humber’s carbon footprint per head of population is bigger than anywhere else in the country. At an international level it’s the second largest industrial cluster by CO2 emissions in the whole of Western Europe. If the UK is to reach net zero, the Humber must decarbonise. And carbon capture and storage will be instrumental in achieving that.

The scale of the challenge in the Humber also makes it an opportunity to significantly reduce the country’s overall emissions and break new ground, implementing carbon capture innovations across a wide range of industries. These diverse businesses can be united in their collective efforts and connected through shared decarbonisation infrastructure – equipment to capture emissions, pipelines to transport them, and a shared site to store them safely and permanently.

Economies of scale through shared infrastructure

The idea of a CO2 transport pipeline traversing the Humber might sound unusual, but large-scale natural gas pipelines have criss-crossed the region since the late 1960s when gas was dispatched from the Easington Terminal on the east Yorkshire coast under the Humber to Killingholme in North Lincolnshire. Further, the UK’s existing legislation creates an environment to ensure they can be operated safely and effectively. CO2 is a very stable molecule, compared to natural gas, and there are already thousands of miles of CO2 pipelines operating around the US, where it’s historically been used in oil recovery.

A shared pipeline also offers economies of scale for companies to implement carbon capture, allowing the Humber’s cluster of carbon-intensive industries to invest in vital infrastructure in a cost-effective way. The diversity of different industries in the region, from renewable baseload power generation at Drax to cutting-edge hydrogen production, also offers a chance to experiment and showcase what’s possible at scale.

The Humber’s position as an estuary onto the North Sea is also advantageous. Its expansive layers of porous sandstone offer an estimated 70 billion tonnes of potential CO2 storage space.

The Humber Estuary

 

But this isn’t just an opportunity to decarbonise the UK’s most emissions-intensive region, it’s a stage to present a new green industrial hub to the world. A hub that could create as many as 47,800 jobs, including high quality technical and construction roles, as well as other jobs throughout supply chains and the wider UK economy.

British innovation as a global export

As industries of all kinds across the world race to decarbonise, there’s an increasing demand for products with green credentials. If we can decarbonise products from the region, such as steel, it will give UK businesses a global edge. Failure to follow through on environmental ambitions, however, will not just damage the cluster’s status, it will put hundreds of thousands of jobs at risk.

Breaking new ground is difficult but there are first-mover advantages. The products and processes trialled and run at scale within the Humber offer intellectual property that industrial hubs around the world are searching for, creating a new export for the UK.

But this vision of a decarbonised Humber, that exports both its products and knowledge to the world, is only possible if we take the right action now. We have a genuine global leadership position. If we don’t act now, that will be lost.

Through projects like Zero Carbon Humber and the East Coast Cluster, alongside Net Zero Teesside, the region’s businesses have shown our collective commitment to implementing decarbonisation at scale through collaboration.

As a Track 1 cluster, the Humber presents one of the UK’s greatest opportunities to level up – attracting global businesses and investors, as well as protecting and creating skilled jobs. We need to seize this moment and put in place the infrastructure that will put the Humber at the forefront of a low-carbon future.

An introduction to carbon accounting

12 May 2022

Sustainable business

Key takeaways:

  • Tracking, reporting, and calculating carbon emissions are a key part of progressing countries, industries, and companies towards net zero goals.
  • As a newly established discipline, carbon accounting still lacks standardisation and frameworks in how emissions are tracked, reduced, and mitigated.

How can countries and companies find a route to net zero emissions? Many organisations, countries and industries have pledged to balance their emissions before mid-century. They intend to do this through a combination of cutting emissions and removing carbon from the atmosphere.

Tracking and quantifying emissions, understanding output, reducing them, and setting tangible targets that can be worked towards are all central to tackling climate change and reducing greenhouse gas emissions – especially when it comes to carbon dioxide (CO2). Emissions and energy consumption reporting is already common practice and compulsory for businesses over a certain size in the UK. However, carbon accounting takes this a step further.

“Carbon reporting is a statement of physical greenhouse gas emissions that occur over a given period,” explains Michael Goldsworthy, Head of Climate Change and Carbon Strategy at Drax. “Carbon accounting relates to how those emissions are then processed and counted towards specific targets. The methodologies for calculating emissions and determining contributions against targets may then have differing rules depending on which framework or standard is being reported against.”

Carbon accounting tools can help companies and counties understand their carbon footprint – how much carbon is being emitted as part of their operations, who is responsible for them, and how they can be effectively mitigated.

Like how financial accounting may seek to balance a company’s books and calculate potential profit, carbon accounting seeks to do the same with emissions, tracking what an entity emits, and what it reduces, removes, or mitigates. Carbon accounting is, therefore, crucial in understanding how countries and companies can contribute to reaching net zero.

A new space

How different organisations, countries and industries approach carbon accounting is still an evolving process.

“It’s as complex as financial accounting, but with financial accounting, there’s a long standing industry that relies on well-established practices and principles. Carbon accounting by contrast is such a new space,” explains Goldsworthy.

Regardless of its infancy, businesses and countries are already implementing standardised approaches to carbon accounting. Regulations such as emissions trading schemes and reporting systems, such as Streamlined Energy and Carbon Reporting (SECR) and the Taskforce on Climate Related Financial Disclosure (TCFD), are beginning to deliver some degree of consistency in businesses’ carbon reporting.

Other standards such as the GHG Protocol have sought to provide a standardised basis for corporate reporting and accounting. Elsewhere, voluntary carbon markets (e.g. carbon offsets) have also evolved to allow transferral of carbon reductions or removals between businesses, providing flexibility to companies in delivering their climate commitments.

The challenge is in aligning these frameworks so that they work together. For example, emissions within a corporate inventory or offset programme must be accounted for in a way that is consistent with a national inventory.

To date, these accounting systems have evolved independently with different rules and methodologies. Beginning to implement detailed carbon accounting, upon which emissions reductions and removals can be based, requires standardised understanding of what they are and where they come from.

Reporting and tackling Scope One, Two, and Three emissions

The main carbon accounting standard used by businesses is the Greenhouse Gas (GHG) Protocol. This voluntary carbon reporting standard can be used by countries and cities, as well as individual companies globally.

The GHG protocol categorises emissions in three different ‘scopes’, called Scope 1, Scope 2, and Scope 3. Understanding, measuring, and reporting these is a key factor in carbon accounting and can drive meaningful emissions reduction and mitigation.

Scope One – Direct emissions

Scope One emissions are those that come as a direct result of a company or country’s activities. These can include fuel combustion at a factory’s facilities, for example, or emissions from a fleet of vehicles.

Scope One emissions are the most straightforward for an organisation to measure and report, and easier for organisations to directly act on.

Scope Two – Indirect energy emissions

Scope Two emissions are those which come from the generation of energy an organisation uses. These can include emissions form electricity, steam, heating, and cooling.

A business may buy electricity, for example, from an electricity supplier, which acquires power from a generator. If that generator is a fossil-fuelled power station the energy consumer’s Scope Two emissions will be greater than if it buys power from a renewable electricity supplier or generates its own renewable power.

The ability to change energy suppliers makes Scope Two relatively straightforward for organisations to act on, assuming renewable energy sources are available in the area.

Scope Three – All other indirect emissions

Scope Three is much broader. It covers upstream and downstream lifecycle emissions of products used or produced by a company, as well as other indirect emissions such as employee commuting and business travel emissions.

Identifying and reducing these emissions across supply and value chains can be difficult for businesses with complex supply lines and global distribution networks. They are also hard for companies to directly influence.

Add in factors like emissions mitigations or offsetting, and the carbon accounting can quickly become much more complex than simply reporting and reducing emissions that occur directly from a company’s activities. Nevertheless, these full-system overviews and whole-product lifecycle accounting are crucial to understanding the true impact of operations and organisations, and to reach climate goals.

Working to timelines

Setting goals with defined timelines and the development of rules that ensure consistent accounting is also crucial to implementing effective climate change mitigation frameworks throughout the global economy. Consider the UK’s aim to be net zero by 2050, or Drax’s ambition to be net negative by 2030, as goals with set timelines.

For many technologies, the time scales over which targets are set have added relevance. There are often upfront emissions to account for and operational emissions that may change over time. Take for example an electric vehicle: the climate benefit will be determined by emissions from construction and the carbon intensity of the electricity used to power it.

Looking at a brief snapshot at the beginning of its life, say the first couple of years, might not show any climate benefit compared to a vehicle using an internal combustion engine. Over the lifetime of the vehicle, however, meaningful emissions savings may become clear – especially if the electricity powering the vehicle continues to decarbonise over time.

This provides a challenge when setting carbon emissions targets. Targets set too far in the future potentially risk inaction in the short term, while targets set over short periods risk disincentivising technologies that have substantial long-term mitigation potential. 

Delivering net zero

Some greenhouse gas emissions will be impossible to fully abate, such as methane and nitrous oxide emissions from agriculture, while other sectors, like aviation, will be incredibly difficult to fully decarbonise. This makes carbon removal technologies all the more critical to ensuring net zero is achieved.

Technologies such as bioenergy with carbon capture and storage (BECCS) – which combines low-carbon, biomass-fuelled renewable power generation with carbon capture and storage (CCS) to permanently remove emissions from the atmosphere – are already under development.

However, it is imperative that such technologies are accounted for using robust approaches to carbon accounting, ensuring all emission and removals flows across the value chain are accurately calculated in accordance with best scientific practice. In the case of BECCS, it’s vital that not only are emissions from processing and transporting biomass considered, but also its potential impact on the land sector.

Forests from which biomass is sourced will be managed for a variety of reasons, such as mitigating natural disturbance, delivering commercial returns, and preserving ecosystems. Accurate accounting of these impacts is therefore key to ensuring such technologies deliver meaningful reductions in atmospheric CO2within timeframes guided by science.

Accounting for net zero

While carbon accounting is crucial to reaching a true level of net zero in the UK and globally, where residual emissions are balanced against removals, the practice should not be used exclusively to deliver numerical carbon goals.

“To deliver net zero, it’s vital we have robust carbon accounting systems and targets in place, ensuring we reduce fossil emissions as far as possible while also incentivising carbon removal solutions,” says Goldsworthy.

“However, many removal solutions rely on the natural world and so it is critical that ecosystems are not only valued on a carbon basis but consider other environmental factors such as biodiversity as well.”

Why and how is carbon dioxide transported?

11 April 2022

Carbon capture

What is carbon transportation?

Carbon transportation is the movement of carbon from one place to another. In nature, carbon moves through the carbon cycle. In industries like energy, however, carbon transportation refers to the physical transfer of carbon dioxide (CO2) emissions from the point of capture to the point of usage or storage.

Why does carbon need to be transported?

Anthropogenic (man-made) CO2 released in processes like power generation leads to the direct increase of CO2 in the atmosphere and contributes to global warming.

However, these emissions can be captured as part of carbon capture and storage (CCS). The CO2 is then transported for safe and permanent storage in geological formations deep underground.

Capturing and storing CO2 prevents it from entering the atmosphere and contributing to global warming. Processes that can deliver negative emissions – such as bioenergy with carbon capture and storage (BECCS) and direct air capture and storage (DACS) – aim to permanently remove CO2 from the atmosphere through CCS.

In CCS, carbon must be transported from the site where it’s captured to a site where it can be permanently stored. This means it needs to travel from a power station or factory to a geological formation like a saline aquifer or depleted oil and gas reservoirs.

As of September 2021, there were 27 operational CCS facilities around the world, with the combined capacity to capture around 40 million tonnes per annum (Mtpa) of CO2. It’s estimated that the UK alone has 70 billion tonnes of potential CO2 storage space in sandstone rock formations under the North Sea.

How is carbon transported?

CO2 can be transported via trucks or ships, but the most common and efficient method is by pipeline. Moving gases of any kind through pipelines is based on pressure. Gases travel from areas of high pressure to areas of low pressure. Compressing gas to a high pressure allows it to flow to other locations.

Gas pipelines are common all around the world, including those transporting CO2. In the US there are, for instance, more than 50 CO2 pipelines – covering around 6,500 km and transporting approximately 68 million tonnes of CO2 a year.

Gas takes up less volume when it’s compressed, and even less when it is liquefied, solidified, or hydrated. Therefore, before being transported, captured CO2 is often compressed and liquefied until it becomes a supercritical fluid.

In a supercritical state, CO2 has the density of a liquid but the viscosity (thickness) of a gas and is, therefore, easier to transport through pipelines. It’s also 50-80% less dense than water, with a viscosity that is 100 times lower than liquid.

This means it can be loaded onto ships in greater quantities and that there is less friction when it’s moving through pipes and, subsequently, into geological storage sites.

How safe is it to transport carbon?

It’s no riskier to transport CO2 via pipeline or ship than it is to transport oil and natural gas, and existing oil and natural gas pipelines can be repurposed to transport CO2.

To enable the safe use of CO2 pipelines, CCS projects must ensure captured CO2 complies with strict purity and temperature specifications, as well as making sure CO2 is dry and free from impurities that could impact pipelines’ operations.

Whilst there are a growing number of CCS transport systems around the world, CCS is still is a relatively new field but research is underway to identify best practises, materials and technologies to optimise the process. This includes research around potential risks and techniques for leak mitigation and remediation.

In the UK, the Health and Safety Executive regulates health, safety, and integrity issues for all natural gas pipelines, which are covered by legislation. The legislation ensures the safety of pipelines, pressure systems and offshore installations and can serve as a strong foundation for CO2 transport regulation.
