California regulators said this year that the state will need 1 gigawatt of long-duration storage by 2026. But the technologies that can cost-effectively meet that need have so far attracted more attention from white-paper authors than paying customers.

In doing so, they beat the state’s investor-owned utilities in making good on the California Public Utilities Commission’s call to invest in this resource.
