Potential to expand system
A long-duration energy storage system that will integrate short-duration batteries and long-duration fuel cells is being planned for California.
Energy Vault Holdings and Pacific Gas and Electric Company (PG&E) are partnering to deploy and operate a utility-scale battery plus green hydrogen long-duration energy storage system (BH-ESS) with a minimum of 293 MWh of dispatchable carbon-free energy.
The hybrid system will be capable of powering approximately 2000 electric customers within PG&E’s Calistoga microgrid for up to 48 hours during a planned outage, the companies said.
The storage system is the first-of-its-kind and integrates a short-duration battery system, for grid forming and black start capabilities, with a long-duration fuel cells plus green liquid hydrogen storage system, the companies said.
