California is facing a huge shortfall of electricity capacity on its grid and advanced compressed air energy storage (A-CAES) can fill the gap, Hydrostor has proposed.

The Canadian federal government is financially supporting the development of a large-scale advanced compressed air energy storage (A-CAES) project capable of providing up to 12 hours of energy storage.

Storelectric CTO Mark Howitt puts forward the case for his company’s ‘innovative’ adiabatic compressed air energy storage, which he claims is a long duration technology complementary to other existing and advanced tech such as batteries.

While lithium-ion batteries get most of the headlines, long-duration solutions of various types are gaining ground. Alice Grundy and Andy Colthorpe profile some of the established and emerging concepts in this increasingly important field.

Compressed Air Energy Storage (CAES) company Hydrostor has introduced Hydrostor Terra — a long-duration bulk energy storage system that is expected to compete with new natural gas plants.
