A study here casts doubt on the feasibility of CCS. The authors state that the studies to date underestimate the amounts of storage that will be required by a factor of between five and twenty times. CCS is one of those technologies that are crucial to managing the transition from a fossil fuel based economy to a clean fuel based one. It is a get-out-of-jail card for the oil industry, allowing them to continue doing what they are doing in the expectation that CCS will make fossil fuel burning feasible for the remaining life of available deposits. This study, suggests that an area the size of a ‘small US state would be needed to store the CO2 produced by a commercial power station. This one will run and run.
