Carbon capture and storage remains firmly on the agenda as a way of mitigating at least some of the impacts of climate change. But time in which to implement large-scale permanent solutions to the storage of waste carbon dioxide is fast running out. One of the reasons why CCS remains popular is that most of the key building bricks to its enablement exist and are well proven. There is the comfort of living carbon capture exemplars, in particular the Equinor-operated Sleipner gasfield in the Norwegian sector of the North Sea, where the high CO2 content of the reservoir is stripped on site and injected below ground while the cleaned natural gas is exported ashore. And yet, for nigh on 20 years, the UK has blown hot and cold on CCS – largely on cost grounds. Although more imaginative alternatives have come forward over the last few years, dumping below ground appears to be the only large-scale, implementable option at this time.
