Empty Promises of Carbon Capture Tech Are No Excuse To Dig Up More Fossil Fuels

The idea that a technology called carbon capture and storage (CCS) could catch molecules of CO₂ as they emerge from the chimneys of power stations and factories has been around for more than two decades. Michael Gove, the secretary of state responsible for “levelling up” the UK’s regions, recently justified his approval of the UK’s first new coal mine in 30 years with “increased use of CCS”. There’s only one problem: CCS won’t cancel out Woodhouse Colliery’s emissions, which are estimated at 400,000 tonnes a year, because it barely exists.

The UK government first started talking about CCS in the late 1990s, when it was looking to meet and exceed its commitment to cut emissions under the Kyoto Protocol.

The fact that developing countries like China and India were planning to burn coal for decades made the UK consider starting a CCS industry as its “gift to the world”, in the words of one senior lobbyist I interviewed for research into industrial decarbonisation.

It’s obvious why oil and gas companies like the idea of CCS. Fossil fuel firms can keep extracting and selling their product (coking coal for the steel industry in the case of the new mine in Cumbria, north-west England, almost all of which is expected to be exported) and mopping up the climate-wrecking emissions is someone else’s responsibility. Politicians have been more circumspect. Some have chafed at the enormous upfront cost of developing and installing CCS and sinking taxpayers’ money into a potential white elephant.

Over the last 20 years in the UK, the future potential of CCS has been used to justify prolonging coal power, making hydrogen fuel from the potent greenhouse gas methane and building more gas-fired power stations.

Advocates of a greenhouse gas removal industry which would scrub excess carbon dioxide from the atmosphere now envisage a vast network of pipes and ships transporting captured CO₂ to storage facilities. One group known as the Coalition for Negative Emissions, composed of energy firms and airlines among other companies, sees the potential in CCS to allow societies to “decarbonise while ensuring continued economic progress”. It also points out, (fairly, in my opinion) that “the enabling infrastructure [has] significant scale-up times [and] this acceleration needs to start today”.

Amid all these breathless position papers and adverts, it can be easy to forget that pilot programmes for CCS have been plagued by cost-overruns and operational failures. CCS is still many years away from making a dent in humanity’s emissions, even if everything goes much more smoothly than it has – repeatedly – in the past.

To use the possible commercial existence of CCS some time in the future as a reason to wave through a high-carbon development now, as Gove has done, is a good example of what some fellow academics have called “mitigation deterrence”.

Meaning, efforts at mitigating climate change (by reducing the amount of carbon spewed into the atmosphere) are deterred by the real or imagined existence of future technologies that might work. It’s the equivalent of smoking more and more cigarettes each day and gambling that a cure for cancer will exist by the time you need it.
