Hydrostor “remains fully committed” to its 4GWh advanced compressed air energy storage (A-CAES) project in California, its president told Energy-Storage.news as it considers alternative locations and delivery dates.

Utility Eneco and Corre Energy have signed an agreement for the latter to deploy a 320MW, 84-hour duration compressed air energy storage system (CAES) in Groningen, the Netherlands.

Hydrostor waits to hear if one of its proposed large-scale projects in California will get approved to supply electricity.
