In a relocation that has actually triggered prevalent criticism from researchers and political leaders alike, the UK federal government has actually authorized strategies to set up carbon capture innovation at Britain’s biggest power plant.
Under the strategies, power generator Drax will set up so-called bioenergy with carbon capture and storage (BECCS) innovation at 2 of 4 biomass systems at the Drax power station in Yorkshire.
Drax changed from burning coal to burning biomass– mainly wood pellets– in 2019. The Drax power station, which produces around 4% of the UK’s power, mainly burns wood imported from North America.
In spite of the switch, the plant was determined in 2015 by environment think tank Ember as the nation’s single biggest CO2 emitter

According to Drax, its power station is environment neutral since the emissions from the wood it burns are balanced out by the CO2 soaked up by growing back trees in location of those that were cut down.
By including BECCS, the power station would end up being the world’s very first “carbon-negative” power plant and the biggest carbon capture plant worldwide, the business declares.
The company indicates research study released (albeit commissioned by the power business) from independent consultancy Baringa, recommending the plant would remove 8 million tonnes of CO2 from the environment yearly.
“This research study reveals BECCS at Drax Power Station uses the most affordable, simple, and effective method to assist the nation satisfy environment targets and might conserve billions of pounds, eliminate countless tonnes of carbon from the environment, and support the UK’s energy security,” stated Will Gardiner, CEO of Drax Group.
Drax’s carbon capture systems are set to be set up in 2030.
How will it work?
BECCS is generally like putting a huge cover on a power plant, catching its emissions, and saving them underground in liquid kind.
Under the authorized strategies, after the pellets are burned to produce power, flue gas including released co2 would be cooled and dealt with before being sent out through an absorption tower to get rid of the greenhouse gas.
Within this absorption tower, the cooled and dealt with gas would go through a chain reaction utilizing amine solvent, which is a substance of ammonia.
The resultant compound would then be reheated to produce a pure stream of co2, which would consequently be transferred through repurposed pipelines to be saved underneath the North Sea.
The entire job is anticipated to cost in the area of ₤ 2bn, a big portion of which will require to be offered by the British federal government.
‘UK’s next white elephant advancement’
Drax declares that the retrofit will make it the world’s biggest carbon capture centerBECCS has actually never ever been carried out on such a big scale and lots of doubts hang over its reliability as a sustainable energy source.
The upgrade is likewise anticipated to cost the taxpayer a massive ₤ 43bn in additional costs over the next 25 years, according to Ember.
3 conservative MPs have actually criticised strategies to continue aids for Drax. “The proposed innovation is not shown,” stated MP Peter Bottomley. “There need to be no more aids for burning trees in our power stations beyond 2027 agreements. The Government needs to rather concentrate on increasing tree cover and support wind, solar and atomic energy.”
If the reasoning that burning trees benefits the environment sounds too great to be real, it’s due to the fact that it most likely is.
A 2018 research study led by John David Sterman from MIT discovered that it would use up to 100 years for replanted trees to draw up the comparable quantity of carbon given off in biomass plants. In the meantime, all that carbon would remain in the environment, worsening environment modification.
“Planning consent isn’t much usage if it’s for an innovation that does not exist yet, wrecks the world’s forests, and is most likely too costly for the UK to ever manage,” stated Matt Williams, senior supporter at the Natural Resources Defense Council, a US-based ecological advocacy group“This might be the UK’s next huge white elephant advancement.”
The root of the issue
For many years, Drax has actually been gaining from substantial federal government rewards based upon the pretence that its power plant is among the UK’s biggest manufacturers of renewable resource– which stood at around 9% in 2021, equating to 4% of the nation’s overall energy production.
According to the Natural Resources Defense Council, the extensive assistance for biomass energy comes from 2009, when the EU specified burning wood for power as a renewable resource source as part of its Renewable Resource Directive
“When these EU policies were very first showing up, there seemed an authentic misconception about the carbon effects from biomass,” describes Heather Hillaker, a personnel lawyer with the ecological not-for-profit Southern Environmental Law Center (SELC). “This is not the wonderful option we’ve been trying to find to eliminate environment modification.”
There’s the truth that some really huge concerns exist around the sustainability of the wood pellets Drax burns at its plant. A BBC examination in 2022 discovered that a few of Drax’s wood originated from fully grown forests in Canada that would take generations to grow back.
“The genuine factor Drax is promoting BECCS is since they understand they will not be enabled to continue burning trees unabated without the pledge of recording the carbon at some point in the future and the UK federal government has actually succumbed to the lie,” stated Katy Brown from British project group Biofuelwatch.
Our take
Drax’s carbon capture prepares look more like a wolf in sheep’s clothes than a real option to the environment crisis.
The 8 million tonnes of carbon cost savings that Drax indicate rests on one essential presumption: that the carbon launched when wood pellets are burned is regained by brand-new development.
A number of independent examinations and research study documents recommend otherwise. To us, this looks like some smart carbon accounting on Drax’s part.
With the huge selection of tested renewable resource innovations offered today, at a lower expense, it appears silly– to state the least– to keep pumping taxpayers’ cash into innovations that might possibly make environment modification even worse.
Whether the Drax BECCS job will get the federal government backing it requires now rests with the Tory federal government– who have not precisely had a great performance history of sound ecological decision-making.
