For the UK to reach net zero CO2 emissions by 2050 and do its part in tackling the biggest challenge of our time, all sectors of the economy must reduce their emissions and do it quickly.

I believe the best approach to tackling climate change is through ‘co-benefit’ solutions: solutions that not only have a positive environmental impact, but that are economically progressive for society today and in the future through training, skills and job creation.

As an energy company, this task is especially important for Drax. We have a responsibility to future generations to innovate and use our engineering skills to deliver power that’s renewable, sustainable and that doesn’t come at a cost to the environment.

Our work on Zero Carbon Humber, in partnership with 11 other forward-thinking organisations, aims to deploy the negative emissions technology BECCS (bioenergy with carbon capture and storage), as well as CCUS (carbon capture, usage and storage) in industry and power, and ramp up hydrogen production as a low carbon fuel. These are all essential technologies in bringing the UK to net zero, but they are also innovative projects at scale that can benefit society and the lives of people in the Humber, and around the UK.

New jobs in a new sector

The Humber region has a proud history in heavy industries. What began as a thriving ship building hub has evolved to include chemicals, refining and steel manufacturing. However, these emissions-intensive industries have grown increasingly expensive to operate and many have left for countries where they can be run cheaper, leading to a decline in the Humber region.

If they are not decarbonised, these industries will face an even greater cost. By 2040, emitters could face billions of pounds per year in carbon taxes, making them less competitive and less attractive for international investment.

Deploying carbon capture and hydrogen are essential steps towards modernising these businesses and protecting up to 55,000 manufacturing and engineering jobs in the region.

A report by Vivid Economics commissioned by Drax, found that carbon capture and hydrogen in the Humber could create and support almost 48,000 new jobs at the peak of the construction period in 2027 and provide thousands of long term, skilled jobs in the following decades.

As well as protecting people’s livelihoods, decarbonisation is also a matter of public health. In the Humber alone, higher air quality could save £148 million in avoided public health costs between 2040 and 2050.

I believe the UK is well position to rise to the challenge and lead the world in decarbonisation technology. There is a clear opportunity to export knowledge and skills to other countries embarking on their own decarbonisation journeys. BECCS alone could create many more jobs related to exporting the technology and operational know-how and deliver additional value for the economy. As interest in negative emissions grows around the world, the UK needs to move quickly to secure a competitive advantage.

A fairer economy

This is in many ways the start of a new sector in our economy – one that can offer new employment, earnings and economic growth. It comes at just the right time. Without intervention to spur a green recovery, the COVID-19 crisis risks subjecting long-term economic damage.

Being at the beginning of the industrial decarbonisation journey means we also have the power to shape this new industry in a way that spreads the benefits across the whole of the UK.

We’ve previously seen sector deals struck between the government and industry include equality measures. For example, the nuclear industry aims to count women as 40% of its employees by 2030, while offshore wind is committed to sourcing 60% of its supply chain from the UK.

At present, the Humber region receives among the lowest levels of government investment in research and development in the UK, contributing to a pronounced skills gap among the workforce. In addition, almost 60% of construction workers across the wider Yorkshire and Humber region were furloughed as of August 2020.

A project such as Zero Carbon Humber could address this regional imbalance and offer skilled, long term jobs to local communities. That’s why I welcome the Prime Minister’s announcement of £1bn investment to support the establishment of CCUS in the Humber and other ‘SuperPlaces’ around the UK.

As the Government’s Ten Point Plan says, CCUS can ‘help decarbonise our most challenging sectors, provide low carbon power and a pathway to negative emissions’. 

Healthier forests

The co-benefits of BECCS extend beyond our communities in the UK. We aim to become carbon negative by 2030 by removing our CO2 emissions from the atmosphere and abating emissions that might still exist on the UK’s path to net zero.

This ambition will only be realised if the biomass we use continues to be sourced from sustainable forests that positively benefit the environment and the communities in which we and our suppliers operate.

I believe we must continuously improve our sustainability policy and seek to update it as new findings come to light. We can help ensure the UK’s biomass sourcing is led by the latest science, best practice and transparency, supporting healthy, biodiverse forests around the world; and even apply it internationally.

Global leadership

Delivering deep decarbonisation for the UK will require collaboration from industries, government and society. What we can achieve through large-scale projects like Zero Carbon Humber is more than just the vital issue of reduced emissions. It is also about creating jobs, protecting health and improving livelihoods.

These are more than just benefits, they are the makings of a future filled with opportunity for the Humber and for the UK’s Green Industrial Revolution.

By implementing the Ten Point Plan and publishing its National Determined Contributions (NDCs) ahead of COP26 in Glasgow next year, the UK continues to be an example to the world on climate action.

Jobs, skills, zero emissions – the economic need for carbon capture by Drax

18 November 2020

Carbon capture

The Humber Estuary is one of the most distinctive features of the UK’s eastern coastline. Viewed from above, it is a crack in the land where the North Sea merges with England – it’s this connection to the sea that has defined it as a region and led to its rich industrial history.

But in recent years, as sectors such as heavy manufacturing move overseas, the Humber has begun to sink into economic decline. These challenges are now being exacerbated by COVID-19 – almost 60% of workers in the Yorkshire and the Humber construction industry were furloughed in August 2020.

Stimulation is needed to rejuvenate the Humber and prevent lasting economic scars on the region and its working-age population. Decarbonisation offers the opportunity to rebuild the region for the 2020s and decades ahead.

Technologies that have been identified as essential for the UK to reach its legally-binding commitment of net zero greenhouse gas emissions by 2050 include:

  • Carbon capture usage and storage (CCUS) – trapping, transporting and storing or recycling carbon dioxide (CO2) from industrial processes and energy generation
  • Bioenergy with carbon capture and storage (BECCS) – carbon removal from renewable, sustainable biomass power generation that leads to negative emissions
  • Hydrogen production – switching processes from natural gas to this zero-emissions fuel

Engineer working inside power stationThe Humber has unique capabilities that positions it as a hub for developing all three.

Zero Carbon Humber (ZCH), the partnership between a number of leading companies (including Drax), aims to bring together these essential technologies and create the foundations from which the region’s emissions-heavy industries can regain their competitive edge, create jobs and rejuvenate the area.

A new report by Vivid Economics for Drax investigates the potential economic impact of carbon capture and hydrogen. It concluded that nearly 48,000 jobs could be created and supported in the industrial cluster at the peak of the construction phase in 2027.

It’s a chance to not just revitalise a powerhouse of Northern England, but to collaborate with other industrial clusters and build a UK-wide green economy ready to export globally and attract international business to the region.

Rejuvenating the Humber

The North Sea has helped forge Hull’s strong industrial heritage of ship building and fishing. In the 1950s the flat lands of the south bank enabled post-war industries such as refining chemicals and steel to thrive.

“The region’s economy is built around the ports and accessibility to Europe and the North Sea,” explains Pauline Wade, Director of International Trade at the Hull and Humber Chamber of Commerce. “They are the biggest ports in the UK in terms of tonnage, and the energy and chemical industries hinge on materials coming in and going out of them.”

But these are also emissions-intensive industries, and as a result the Humber has the highest CO2 emissions of any UK industrial region – emitting 30% more than the second largest industrial cluster. Decarbonisation is vital in modernising and protecting these sectors, and the 55,000 manufacturing jobs they support.

“Decarbonisation brings opportunities. Many businesses in this region have that target very firmly set in their business plans,” says Beckie Hart, Regional Director of the Yorkshire and the Humber CBI (Confederation of British Industry). “Many are high polluters – they know that, but they are very keen to became part of the solution.”

Developing BECCS, CCUS and hydrogen, as well as building the infrastructure needed to capture and transport CO2, offers both immediate construction jobs and long-term skilled jobs.

The main construction period of the project would run from 2024 to 2031 and support up to 47,800 new jobs at its peak in 2027, when £3.1 billion a year would be added to the regional economy. These include up to 25,200 high quality jobs in construction and operations, as well as a further 24,400 supported across the supply chain and wider economy.

These construction roles include jobs such as welders, pipe fitters, machine installers and technicians – with immediate government backing, these jobs could be available in as little as four years. Ongoing operations will also create 3,300 long term, skilled jobs in the cluster in the early 2030s.

The supply chain needed to provide the materials and parts for the region’s industrial revitalisation will also support further indirect jobs. In fact, businesses of all kinds stand to benefit – the increased spending by workers also could support further jobs across businesses ranging from cafes to professional services. These indirect jobs go on to induce further employment and spending out across more of the economy.

Overall the report suggests an annual average of more than 7,000 indirect and around 10,800 induced jobs could be supported during the construction phase, with £452 million in indirect and £581 million in induced value added to the wider economy annually on average.

However, transformation is costly and today the Humber region receives among the lowest levels of government investment in research and development in the UK. This has contributed to a pronounced skills gap in the region, as opportunities decline, and more people fall out of the workforce.

Bridging the skills gap in the Humber

Projects such as ZCH depend on availability of skilled workforces to build and operate the next generation of energy technologies. However, the Humber currently has a low proportion of school leavers with the right qualifications to take on roles with specialist technical and practical skills.

This skills gap is only expected to get worse. The Government’s Working Futures model forecasts that from 2022 key sectors such as electricity and gas, engineering and construction in the region will require higher qualifications than are currently available in the local labour market.

The skills gap is also compounded by COVID-19. As it creates economic uncertainty it pushes more people out of work and further reduces skills in the workforce. This has a particularly pronounced impact on young people who are less established in careers, threatening to create a ‘COVID-Generation’ that feel discouraged and detached from the labour market.

But this is not an inevitability.

With the right intervention from government and business, the Humber’s workforce can be upskilled and drive a green recovery.

A number of different approaches are possible: apprenticeships have historically proved a valuable means of training the next generation of workers. Companies and schools should work together to highlight the opportunities of vocational training to school leavers.

“Universities and colleges must work a lot more closely with the businesses in the region to have an honest conversation about what they need,” explains Hart. “A good example is the Ron Dearing University Technical College. It’s a business-led college that has only been open about 18 months but has had great results from the students because they offer specific courses that the region’s employers actually need.”

For older generations of workers who have been out of the labour force for extended periods of time ‘skills vouchers’ are a timely intervention. These work by offering grants to cover the cost of flexibly retraining, meaning long-term unemployed workers of any age can ease back into new types of jobs.

Training local people for the future is key to decarbonising the Humber and creating jobs, as well as protecting industries. But a net zero industrial cluster could also have an impact beyond just the Humber.

Carbon removal in Yorkshire and the Humber

The Committee on Climate Change (CCC) has made it clear that for the UK to reach net zero by 2050 CCUS and negative emissions from BECCS are essential, as is hydrogen as a zero-carbon source of fuel. These will be needed at scale across the UK, and in the Humber. They are already underway.

Drax Power Station is piloting BECCS technology and has proven it can deliver negative emissions. Generating electricity using biomass from sustainably managed forests that absorb CO2 is a carbon neutral process. As part of the power generation process, adding CCUS and capturing the CO2 emitted, storing it permanently under the North Sea turns the process into a carbon negative one.

Deploying BECCS across four of Drax’s generating units would support 10,304 jobs and create £673 million in value at the peak of the construction phase. When operations get underway as early as 2027, 750 permanent operations and maintenance jobs could be created. Drax aims to operate as a carbon negative power station by 2030.

Of the 10,491 jobs supported by deploying BECCS (10,300 at the peak), 6,367 of these would be within the project’s supply chain and wider economy (9,073 in 2028).

Such supply chains needed across the North of England offer further potential to establish Yorkshire and the Humber as a hub for decarbonisation technology.

Facilities such as an Advanced Manufacturing Research Centre (AMRC) have been proven to make regions of the UK more competitive locations for advanced industries. By bringing together business with universities, they can focus on sector-specific challenges for technical industries. By creating a manufacturing hub dedicated to research and innovation in a specific industry, AMRCs also encourage ‘crowing-in investments.’ This is when private sectors investments enter into a region in the wake of government spending.

A zero carbon technology-focused AMRC in the Humber would also position the region to offer decarbonisation skills and products to other industrial clusters in the UK and further afield.

From the Humber to the world

Up the north coast from the Humber is Net Zero Teesside, a neighbouring industrial cluster with its own aims for decarbonisation. Through collaboration with clusters such as this, ZCH can offer even wider reaching benefits and enable UK-wide carbon capture, negative emissions and hydrogen.

However, for the entire UK to reach net zero, clusters all across the country must decarbonise – the report suggests as much as 190 million tonnes (Mt) CO2 could be captured and stored every year across the country.

Beyond just the clusters themselves 193,000 jobs could be created at the peak for UK deployment in 2039. These jobs would add £13.9 billion in value to the economy.

Under the Humber Bridge

Building a strong zero carbon economy based around the combined strengths of BECCS, CCUS and hydrogen can provide the UK with a world-leading export. At a time when countries across the globe all face the same decarbonisation challenges, successfully building clusters like ZCH will allow the UK to export knowledge, skilled labour, technology and services around the world.

“As a port city, Hull has always had an international influence. The chamber of commerce was set up in 1837 by the merchant adventurers who were seafaring traders. That history is inbuilt into the local DNA,” says Wade. “Today, we’re trying to create the environment for international companies to invest and locate in the Humber.”

It serves as a further example of how investing decisively in projects such as Carbon Capture by Drax and CCUS and hydrogen clusters such as Zero Carbon Humber today will bring long term economic benefits, taking the UK from a green recovery to a world-leading green industrial powerhouse.

“The Humber has evolved from the fishing industry to a generator of high-emissions products like steel, chemicals and power,” explains Hart. “Now it is keen to be the clean corner and teach everyone else how to decarbonise. There is a single vision of where we want to go and how they want to get there jointly.”

COP26: Will countries with the boldest climate policies reach their targets?

30 October 2020

Carbon capture

To tackle the climate crisis, global unity and collaboration are needed. This was in part the thinking behind the Paris Agreement. It set a clear, collective target negotiated at the 2015 United Nations Climate Change Conference and signed the following year: to keep the increase in global average temperatures to well below 2 degrees Celsius above pre-industrial levels.

In November 2021, COP26 will see many of the countries who first signed the Paris Agreement come together in Glasgow for the first ‘global stocktake’ of their environmental progress since its creation.

COP26 will take place at the SEC in Glasgow

Already delayed for a year as a result of the pandemic, COVID-19 and its effects on emissions is likely to be a key talking point. So too will progress towards not just the Paris Agreement goals but those of individual countries. Known as ‘National Determined Contributions’ (NDCs), these sit under the umbrella of the Paris Agreement goals and set out individual targets for individual countries.

With many countries still reeling from the effects of COVID-19, the question is: which countries are actually on track to meet them?

What are the goals?

The NDCs of each country represent its efforts and goals to reduce national emissions and adapt to the impacts of climate change. These incorporate various targets, from decarbonisation and forestry to coastal preservation and financial aims.

While all countries need to reduce emissions to meet the Paris Agreement targets, not all have an equally sized task. The principle of differentiated responsibility acknowledges that countries have varying levels of emissions, capabilities and economic conditions.

The Universal Ecological Fund outlined the emissions breakdown of the top four emitters, showing that combined, they account for 56% of global greenhouse gas emissions. China is the largest emitter, responsible for 26.8%, followed by the US which contributes 13.1%. The European Union and its 28 member states account for nine per cent, while India is responsible for seven per cent of all emissions.

These nations have ambitious emissions goals, but are they on track to meet them?

China

Traffic jams in the rush hour in Shanghai Downtown, contribute to high emissions in China.

By 2030, China pledged to reach peak carbon dioxide (CO2), increase its non-fossil fuel share of energy supply to 20% and reduce the carbon intensity – the ratio between emissions of CO2 to the output of the economy – by 60% to 65% below 2005 levels.

COVID-19 has increased the uncertainty of the course of China’s emissions. Some projections show that emissions are likely to grow in the short term, before peaking and levelling out sometime between 2021 and 2025. However, according to the Climate Action Tracker it is also possible that China’s emissions have already peaked – specifically in 2019. China is expected to meet its non-fossil energy supply and carbon intensity pledges.

United States

The forecast for the second largest emitter, the US, has also been affected by the pandemic. Economic firm Rhodium Group has predicted that the US could see its emissions drop between 20% and 27% by 2025, meeting its target of reducing emissions by 26% to 28% below 2005 levels.

However, President Trump’s rolling back of Obama-era climate policies and regulations, his support of fossil fuels and withdrawal from the Paris Agreement (effective from as early as 4 November 2020), suggest any achievement may not be long-lasting.

The United States’ Coronavirus Aid, Relief, and Economic Security Act, known as the CARES Act, does not include any direct support to clean energy development – something that could also change in 2021.

European Union

The European Union and its member states, then including the UK, pledged to reduce emissions by at least 40% below 1990 levels by 2030 – a target the Climate Action Tracker estimates will be achieved. In fact, the EU is on track to cut emissions by 58% by 2030.

This progress is in part a result of a large package of measures adopted in 2018. These accelerated the emissions reductions, including national coal phase-out plans, increasing renewable energy and energy efficiency. The package also introduced legally binding annual emission limits for each member state within which they can set individual targets to meet the common goal.

The UK has not yet released an updated, independent NDC. However, it has announced a £350 million package designed to cut emissions in heavy industry and drive economic recovery from COVID-19. This includes £139 million earmarked to scale up hydrogen production, as well as carbon capture and storage (CCS) technology, such as bioenergy with carbon capture (BECCS) – essential technologies in achieving net zero emissions by 2050 and protecting industrial regions.

India

India, the fourth largest global emitter, is set to meet its pledge to reduce its emissions intensity by 33% to 35% below 2005 levels and increase the non-fossil share of power generation to 40% by 2030. What’s more, the Central Electricity Agency has reported that 64% of India’s power could come from non-fossil fuel sources by 2030.

Wind turbines in Jaisalmer, Rajasthan, India

Along with increasingly renewable generation, the implementation of India’s National Smart Grid Mission aims to modernise and improve the efficiency of the country’s energy system.

It is promising that the world’s four largest emitters have plans in place and are making progress towards their decarbonisation goals. However, tackling climate change requires action from around the entire globe. In addition to NDCs, many countries have committed to, or have submitted statements of intent, to achieve net zero carbon emissions in the coming years.

Building back better by supporting negative emissions technologies

Dear Chancellor, Secretaries of State,

Building back better by supporting negative emissions technologies

Today our organisations have launched a new coalition with a shared vision: to build back better as part of a sustainable and resilient recovery from Covid-19, by developing pioneering projects that can remove carbon dioxide (CO2) and other pollutants from the atmosphere. Together, we represent hundreds of thousands of workers across some of the UK’s most critical industries, including aviation, energy and farming, each of which contribute billions of pounds each year to the economy.

A growing number of independent experts, including the Committee on Climate Change, Royal Society and Royal Academy of Engineering and the Electricity System Operator, have recognised the crucial role of ‘negative emissions’ or ‘greenhouse gas removal’ technologies in fighting the climate crisis. Whilst we should seek to decarbonise sectors such as aviation, heavy industry and agriculture as far as practically possible, due to technical or commercial barriers it is unlikely we will eliminate their greenhouse gas emissions completely. Negative emissions technologies are critical therefore to balancing out these residual emissions and ensuring we achieve Net Zero in a credible, cost effective and sustainable way.

As well as benefiting the environment, negative emissions technologies and projects can build back a cleaner, greener economy in the wake of Covid-19. The foundations for this are already being laid by our coalition’s members today.

For example:

  • The National Farmers Union has set out a Net Zero vision for the agricultural sector whereby UK farmers harness the ability to capture carbon to create new income streams.
  • The aviation industry through the Sustainable Aviation initiative has identified negative emissions projects, alongside other measures as sustainable jet fuel, as being crucial to greening the industry.
  • In North Yorkshire, Drax is developing plans to combine sustainable biomass with carbon capture technology (BECCS) to create the world’s first carbon negative power station – supporting thousands of jobs in the process.
  • In North East Lincolnshire, Velocys with the support of British Airways is developing the Altalto waste-to-jet fuel project that could produce negative-emission jet fuel once the Humber industrial cluster’s carbon capture and storage infrastructure is established.
  • Finally, Carbon Engineering has announced a partnership with Pale Blue Dot Energy to deploy commercial-scale Direct Air Capture projects in the UK that would remove significant volumes of carbon dioxide from the atmosphere.

With COP26 fast approaching, there is a real and compelling opportunity for the UK Government to demonstrate to the world it is taking a leadership position on negative emissions. Conversely if the UK does not act quickly, it could jeopardise the delivery of projects in the 2020s that can support innovation, learning by doing and the scale-up of negative emissions in the 2030s. It also risks Britain falling behind in the race to scale and commercialise these technologies, with a view to exporting them to other countries around the world to support their own decarbonisation efforts.

We therefore call on this Government, supported by your departments, to pursue the following ‘low regrets’ interventions to support this critical emerging industry:

  1. Adopt a clear, unambiguous commitment to supporting negative emissions in the 2020s and beyond. The last significant reference to negative emissions by Government was in the 2017 Clean Growth Strategy. Between now and the end of the year there is a window of opportunity for the Government to go further, reflecting the changed reality of a Net Zero world and the growing consensus on the need for negative emissions. A clear signal of intent would also give greater confidence to investors and developers in negative emissions projects, in the absence of a long-term strategy.
  2. Develop targeted policies to support viable negative emissions projects in the 2020s. In order to scale up in the 2030s at a pace compatible with the UK’s climate commitments, it is essential that Government works with industry to bring forward early projects in the 2020s that are viable and represent value for money. However, there is no marketplace or regulatory regime in the UK today that incentivises or rewards negative emissions, making financing projects extremely challenging. Dedicated policy frameworks and business models for solutions such as afforestation, BECCS and Direct Air Capture are therefore urgently needed.
  3. Seize the opportunity to make negative emissions a point of emphasis at COP26. The UK has already led the way at a global level by adopting Net Zero as a legally binding target. At COP26, the UK can showcase its further commitment to continuous innovation around the decarbonisation agenda by signposting the early actions it has taken to deploy negative emissions – which other countries will also need to meet their own zero carbon ambitions. This statement would be particularly powerful as it can be credibly supported by several pioneering projects already being undertaken by British businesses and research organisations in this space.

We would welcome the opportunity to meet with each of you to discuss these points in further detail.

Yours,

The Coalition for Negative Emissions

Could hydrogen power stations offer flexible electricity for a net zero future?

26 August 2020

Power generation
Pipework in a chemical factory

We’re familiar with using natural gas every day in heating homes, powering boilers and igniting stove tops. But this same natural gas – predominantly methane – is also one of the most important sources of electricity to the UK. In 2019 gas generation accounted for 39% of Great Britain’s electricity mix. But that could soon be changing.

Hydrogen, the super simple, super light element, can be a zero-carbon emissions source of fuel. While we’re used to seeing it in everyday in water (H2O), as a gas it has been tested as an alternative to methane in homes and as a fuel for vehicles.

Could it also replace natural gas in power stations and help keep the lights on?

The need for a new gas

Car arriving at hydrogen gas station

Hydrogen fuel station

Natural gas has been the largest single source of electricity in Great Britain since around 2000 (aside from the period 2012-14 when coal made a resurgence due to high gas prices). The dominance of gas over coal is in part thanks to the abundant supply of it in the North Sea. Along with carbon pricing, domestic supply makes gas much cheaper than coal, and much cleaner, emitting as much as 60% less CO2 than the solid fossil fuel.

Added to this is the ability of gas power stations to start up, change their output and shut down very quickly to meet sudden shifts in electricity demand. This flexibility is helpful to support the growth of weather-dependant renewable sources of power such as wind or solar. The stability gas brings has helped the country decarbonise its power supply rapidly.

Hydrogen, on the other hand, can be an even cleaner fuel as it only releases water vapour and nitrous oxide when combusted in large gas turbines. This means it could offer a low- or zero-carbon, flexible alternative to natural gas that makes use of Great Britain’s existing gas infrastructure. But it’s not as simple as just switching fuels.

Switching gases

Some thermal power stations work by combusting a fuel, such as biomass or coal, in a boiler to generate intense heat that turns water into high-pressure steam which then spins a turbine. Gas turbines, however, are different.

Engineer works on a turbine at Drax Power Station

Instead of heating water into steam, a simple gas turbine blasts a mix of gas, plus air from the surrounding atmosphere, at high pressure into a combustion chamber, where a chemical reaction takes place – oxygen from the air continuously feeding a gas-powered flame. The high-pressure and hot gasses then spin a turbine. The reaction that takes place inside the combustion chamber is dependent on the chemical mix that enters it.

“Natural gas turbines have been tailored and optimised for their working conditions,” explains Richard Armstrong, Drax Lead Engineer.

“Hydrogen is a gas that burns in the same way as natural gas, but it burns at different temperatures, at different speeds and it requires different ratios of oxygen to get the most efficient combustion.”

Switching a power station from natural gas to hydrogen would take significant testing and refining to optimise every aspect of the process and ensure everything is safe. This would no doubt continue over years, subtly developing the engines over time to improve efficiency in a similar way to how natural gas combustion has evolved. But it’s certainly possible.

What may be trickier though is providing the supply of hydrogen necessary to power and balance the country’s electricity system. 

Making hydrogen

Hydrogen is the most abundant element in the universe. But it’s very rare to find it on its own. Because it’s so atomically simple, it’s highly reactive and almost always found naturally bonded to other elements.

Water is the prime example: it’s made up of two hydrogen atoms and one oxygen atom, making it H2O. Hydrogen’s tendency to bond with everything means a pure stream of it, as would be needed in a power station, has to be produced rather than extracted from underground like natural gas.

Hydrogen as a gas at standard temperature and pressure is known by the symbol H2.

A power station would also need a lot more hydrogen than natural gas. By volume it would take three times as much hydrogen to produce the same amount of energy as would be needed with natural gas. However, because it is so light the hydrogen would still have a lower mass.

“A very large supply of hydrogen would be needed, which doesn’t exist in the UK at the moment,” says Rachel Grima, Research & Innovation Engineer at Drax. “So, at the same time as converting a power plant to hydrogen, you’d need to build a facility to produce it alongside it.”

One of the most established ways to produce hydrogen is through a process known as steam methane reforming. This applies high temperatures and pressure to natural gas to break down the methane (which makes up the majority of natural gas) into hydrogen and carbon dioxide (CO2).

The obvious problem with the process is it still emits CO2, meaning carbon capture and storage (CCS) systems are needed if it is to be carbon neutral.

“It’s almost like capturing the CO2 from natural gas before its combusted, rather than post-combustion,” explains Grima. “One of the advantages of this is that the CO2 is at a much higher concentration, which makes it much easier to capture than in flue gas when it is diluted with a lot of nitrogen.”

Using natural gas in the process produces what’s known as ‘grey hydrogen’, adding carbon capture to make the process carbon neutral is known as ‘blue hydrogen’ – but there are ways to make it with renewable energy sources too.

Electrolysis is already an established technology, where an electrical current is used to break water down into hydrogen and oxygen. This ‘green hydrogen’ cuts out the CO2 emissions that come from using natural gas. However, like charging an electric vehicle, the process is only carbon-neutral if the electricity powering it comes from zero carbon sources, such as nuclear, wind and solar.

It’s also possible to produce hydrogen from biomass. By putting biomass under high temperatures and adding a limited amount of oxygen (to prevent the biomass combusting) the biomass can be gasified, meaning it is turned into a mix of hydrogen and CO2. By using a sustainable biomass supply chain where forests absorb the equivalent of the CO2 emitted but where some fossil fuels are used within the supply chain, the process becomes low carbon.

CCS can then be added to make it carbon negative overall, meaning more CO2 is captured and stored at forest level and in below-ground carbon storage than is emitted throughout its lifecycle. This form of ‘green hydrogen’ is known as bioenergy with carbon capture and storage (BECCS) hydrogen or negative emissions hydrogen.

There are plenty of options for making hydrogen, but doing it at the scale needed for power generation and ensuring it’s an affordable fuel is the real challenge. Then there is the issue of transporting and working with hydrogen.

“The difficulty is less in converting the UK’s gas power stations and turbines themselves. That’s a hurdle but most turbine manufacturers already in the process of developing solutions for this,” says Armstrong.

“The challenge is establishing a stable and consistent supply of hydrogen and the transmission network to get it to site.”

Working with the lightest known element

Today hydrogen is mainly transported by truck as either a gas or cooled down to minus-253 degrees Celsius, at which point it becomes a liquid (LH2). However, there is plenty of infrastructure already in place around the UK that could make transporting hydrogen significantly more efficient.

“The UK has a very advanced and comprehensive gas grid. A conversion to hydrogen would be more economic if you could repurpose the existing gas infrastructure,” says Hannah Steedman, Innovation Engineer at Drax.

“The most feasible way to feed a power station is through pipelines and a lot of work is underway to determine if the current natural gas network could be used for hydrogen.”

Gas stove

Hydrogen is different to natural gas in that it is a very small and highly reactive molecule,  therefore it needs to be treated differently. For example, parts of the existing gas network are made of steel, a metal which hydrogen reacts with, causing what’s known as hydrogen embrittlement, which can lead to cracks and failures that could potentially allow gas to escape. There are also factors around safety and efficiency to consider.

Like natural gas, hydrogen is also odourless, meaning it would need to have an odourant added to it. Experimentation is underway to find out if mercaptan, the odourant added to natural gas to give it a sulphuric smell, is also compatible with hydrogen.

But for all the challenges that might come with switching to hydrogen, there are huge advantages.

The UK’s gas network – both power generation and domestic – must move away from fossil fuels if it is to stop emitting CO2 into the atmosphere, and for the country to reach net zero by 2050. While the process will not be as simple as switching gases, it creates an opportunity to upgrade the UK’s gas infrastructure – for power, in homes and even as a vehicle fuel.

It won’t happen overnight, but hydrogen is a proven energy fuel source. While it may take time to ramp up production to a scale which can meet demand, at a reasonable cost, transitioning to hydrogen is a chance to future-proof the gas systems that contributes so heavily to the UK’s stable power system.

Negative emissions

What are negative emissions?

In order to meet the long-term climate goals laid out in the Paris Agreement, there is a need to not only reduce the emission of harmful greenhouse gases into the air, but actively work to remove the excess carbon dioxide (CO2) currently in the atmosphere, and the CO2 that will continue to be emitted as economies work to decarbonise.

The process of greenhouse gas removal (GGR) or CO2 removal (CDR) from the atmosphere is possible through negative emissions, where more CO2 is taken out than is being put into the atmosphere. Negative emissions can be achieved through a range of nature-based solutions or through man-made technologies designed to remove CO2 at scale.

What nature-based solutions exist to remove CO2 from the atmosphere?

One millennia-old way of achieving negative emissions is forests. Trees absorb carbon when they grow, either converting this to energy and releasing oxygen, or storing it over their lifetime. This makes forests important tools in limiting and potentially reducing the amount of CO2 in the atmosphere. Planting new forests and regenerating forests has a positive effect on the health of the world as a result.

However, this can also go beyond forests on land. Vegetation underwater has the ability to absorb and store CO2, and seagrasses can in fact store up to twice as much carbon as forests on land – an approach to negative emissions called ‘blue carbon’.

Key negative emissions facts

 

Did you know?

Bhutan is the only carbon negative country in the world – its thick forests absorb three times the amount of CO2 the small country emits.

What man-made technologies can deliver negative emissions?

Many scientists and experts agree one of the most promising technologies to achieve negative emissions is bioenergy with carbon capture and storage (BECCS). This approach uses biomass – sourced from sustainably managed forests – to generate electricity. As the forests used to create biomass absorb CO2 while growing, the CO2 released when it is used as fuel is already accounted for, making the whole process low carbon.

By then capturing and storing any CO2 emitted (often in safe underground deposits), the process of electricity generation becomes carbon negative, as more carbon has been removed from the atmosphere than has been added.

Direct air carbon capture and storage (DACCS) is an alternative technological solution in which CO2 is captured directly from the air and then transported to be stored or used. While this could hold huge potential, the technology is currently in its infancy, and requires substantial investment to make it a more widespread practice.

The process of removing CO2 from the atmosphere is known as negative emissions, because more CO2 is being taken out of the atmosphere than added into it.

How much negative emissions are needed?

According to the Intergovernmental Panel on Climate Change, negative emissions technologies could be required to capture 20 billion tonnes of carbon annually to help prevent catastrophic changes in the climate between now and 2050.

What is carbon capture usage and storage?

What is carbon capture usage and storage?

Carbon capture and storage (CCS) is the process of trapping or collecting carbon emissions from a large-scale source – for example, a power station or factory – and then permanently storing them.

Carbon capture usage and storage (CCUS) is where captured carbon dioxide (CO2) may be used, rather than stored, in other industrial processes or even in the manufacture of consumer products.

How is carbon captured?

Carbon can be captured either pre-combustion, where it is removed from fuels that emit carbon before the fuel is used, or post-combustion, where carbon is captured directly from the gases emitted once a fuel is burned.

Pre-combustion carbon capture involves solid fossil fuels being converted into a mixture of hydrogen and carbon dioxide under heat pressure. The separated CO2 is captured and transported to be stored or used.

Post-combustion carbon capture uses the addition of other materials (such as solvents) to separate the carbon from flue gases produced as a result of the fuel being burned. The isolated carbon is then transported (normally via pipeline) to be stored permanently –  usually deep underground – or used for other purposes.

Carbon capture and storage traps and removes carbon dioxide from large sources and most of that CO2 is not released into the atmosphere.

 What can the carbon be used for?

Once carbon is captured it can be stored permanently or used in a variety of different ways. For example, material including carbon nanofibres and bioplastics can be produced from captured carbon and used in products such as airplanes and bicycles, while several start-ups are developing methods of turning captured CO2 into animal feed.

Captured carbon can even assist in the large-scale production of hydrogen, which could be used as a carbon-neutral source of transport fuel or as an alternative to natural gas in power generation.

Key carbon capture facts

Where can carbon be stored?

Carbon can be stored in geological reserves, commonly naturally occurring underground rock formations such as unused natural gas reservoirs, saline aquifers, or ‘unmineable’ coal beds. The process of storage is referred to as sequestration.

The underground storage process means that the carbon can integrate into the earth through mineral storage, where the gas chemically reacts with the minerals in the rock formations and forms new, solid minerals that ensure it is permanently and safely stored.

Carbon injected into a saline aquifer dissolves into the water and descends to the bottom of the aquifer in a process called dissolution storage.

According to the Global CCS Institute, over 25 million tonnes of carbon captured from the power and industrial sectors was successfully and permanently stored in 2019 across sites in the USA, Norway and Brazil. 

What are the benefits of carbon storage?

CO2 is a greenhouse gas, which traps heat in our atmosphere, and therefore contributes to global warming. By capturing and storing carbon, it is being taken out of the atmosphere, which reduces greenhouse gas levels and helps mitigate the effects of climate change.

Carbon capture fast facts

  • CCUS is an affordable way to lower CO2 emissions – fighting climate change would cost 70% more without carbon capture technologies
  • The largest carbon capture facility in the world is the Petra Nova plant in Texas, which has captured a total of 5 million tonnes of CO2, since opening in 2016
  • Drax Power Station is trialling Europe’s biggest bioenergy carbon capture usage and storage project (BECCS), which could remove and capture more than 16 million tonnes of CO2 a year by the mid 2030s, delivering a huge amount of the negative emissions the UK needs to meet net zero

What is decarbonisation?

Decarbonisation

What is decarbonisation?

Decarbonisation is the term used for the process of removing or reducing the carbon dioxide (CO2) output of a country’s economy. This is usually done by decreasing the amount of CO2 emitted across the active industries within that economy. 

Why is decarbonisation important?

Currently, a wide range of sectors – industrial, residential and transport – run largely on fossil fuels, which means that their energy comes from the combustion of fuels like coal, oil or gas.

The CO2 emitted from using these fuels acts as a greenhouse gas, trapping in heat and contributing to global warming. By using alternative sources of energy, industries can reduce the amount of CO2 emitted into the atmosphere and can help to slow the effects of climate change.

Key decarbonisation facts

Why target carbon dioxide?

 There are numerous greenhouse gases that contribute to global warming, however CO2 is the most prevalent. As of 2018, carbon levels are the highest they’ve been in 800,000 years.

The Paris Agreement was created to hold nations accountable in their efforts to decrease carbon emissions, with the central goal of ensuring that temperatures don’t rise 2 degrees Celsius above pre-industrial level.

With 195 current signatories, economies have begun to factor in the need for less investment in carbon, with the UK leading the G20 nations in decarbonising its economy in the 21st century.

How is decarbonisation carried out?

There are numerous energy technologies that aim to reduce emissions from industries, as well as those that work towards reducing carbon emissions from the atmosphere.

Decarbonisation has had the most progress in electricity generation because of the growth of renewable sources of power, such as wind turbines, solar panels and coal-to-biomass upgrades, meaning that homes and businesses don’t have to rely on fossil fuels. Other innovations, such as using batteries and allowing homes to generate and share their own power, can also lead to higher rates of decarbonisation. As the electricity itself is made cleaner, it therefore assists electricity users themselves to become cleaner in the process.

Other approaches, such as reforestation or carbon capture and storage, help to pull existing carbon from the air, to neutralise carbon output, or in some cases, help to make electricity generation – and even entire nations – carbon negative.

Alternative power options means that homes and businesses don’t have to rely on traditional carbon fuels.

What is the future of decarbonisation?

For decarbonisation to be more widely adopted as a method for combating climate change, there needs to be structural economical change, according to Deloitte Access Economics. Creating more room for decarbonisation through investing in alternative energies means that “there are a multitude of job-rich, shovel-ready, stimulus opportunities that also unlock long-term value”.
