The overall cost of carbon carbon storage ( CCS ) technology is greater than cost per MWh , the Energy Technologies Institute ( ETI ) has said . The ill - fated Department of Energy & Climate Change commercialisation scheme was expected to deliver electricity at about £ 170 per MWh after 2020 . But George Day , head of economic strategy at the ETI , said that CCS had integration benefits and that with the right cost - sharing deal , £ 85 / MWh could be achieved . The electricity system is an interconnected whole, so its overall cost reflects the interaction of the whole generation mix. Day added that the costs of CCS can not be reduced , or come down , until there is a commitment to delivering a large - scale project .
