ENERGY STORAGE

A porous medium for all seasons

Nature Energy volume 4, pages 97–98 (2019)Cite this article

Subjects

The answer to seasonal energy storage and security to support highly renewable power systems could lie deep under the seabed, where compressed air energy storage offers a route to long-term storage at large scales. Now, research models the potential for this in porous rock and finds a large capacity in saline aquifers offshore in the UK.
