First comprehensive investigation says potentially disastrous flaws in way government trying to revive commercial interest
Serious doubts have been raised over the prospects for carbon capture and storage in the UK in the first comprehensive investigation into the technology, just two weeks after the government launched a £1bn competition to build the first demonstration CCS plant.
The finding by the government-funded UK Energy Research Council endangers many of the government’s assumptions on tackling climate change, because ministers’ long-term plans rely heavily on making the untried technique work on a massive scale. CCS is designed to lower the carbon emissions of fossil fuel power stations.
The design of the new competition is flawed, and the UK is already falling far behind other countries such as the US in its attempts to commercialise the expensive technique, according to the lead author of the study, which took two years to compile. The technique has never been demonstrated at scale on a working power station.
Jim Watson, lead author of the report, said: “People assumed that CCS would be straightforward, but it has not been. It is a particularly challenging technology – it’s actually very, very difficult.”
The question of the future of CCS is a crucial one because all of the government’s assumptions about how the UK can meet its long term target of cutting emissions by 80% by 2050 require a massive use of CCS technology. If it cannot be made to work commercially, and at a reasonable cost, then the UK would have to spend much more on renewable energy, nuclear power and other economic transformations, and would face having to make enormous cuts in areas such as emissions from air travel.
Watson said he would give the UK “a low grade” for its efforts so far on CCS, and pointed to potentially disastrous flaws in the way the government is attempting to revive commercial interest in the technology. These rest on the long-term support for the technology, which when added to fossil fuel power stations will make them far more expensive to run.
