Hydrostor building up to 1 GW compressed air storage to meet California’s shifting resource needs

4 May, 2021

  • We are developing 1GW of long-duration energy storage in California using patented compressed air technology.
  • The projects, with up to 500 MW capacity each, are expected to come online in 2026, aiming to meet California’s clean energy goals as it moves away from fossil fuels.
  • The state’s interest in long-duration storage is growing, especially after the retirement of the Diablo Canyon nuclear plant.
