HC Deb 10 May 1966 vol 728 c49W
72. Mr. Woodburn

asked the Minister of Power what studies are being made to use surplus night produced electricity by pressurised air storage in disused mines and other underground cavities.

Mr. Marsh

This is primarily a matter for the electricity supply authorities who have made detailed studies to enable them to form technical and economic appraisals of both pressurised-air and pumped-water storage.
