Research carried out jointly by the University of Edinburgh and the University of Strathclyde has indicated that a new technique could be used to trap compressed air in porous rock formations found in the North Sea using electricity from renewable technologies. The pressurised air would then able to create power on demand.
Released on 21 January, the research found that porous rocks beneath UK waters could store about one and a half times the UK’s typical electricity demand for January and February.
Dr Julien Mouli-Castillo said: “It can provide a viable, though expensive, option to ensure the UK’s renewable electricity supply is resilient between seasons. More research could help to refine the process and bring costs down.”
