Energy Vault Holdings has selected Chart Industries to supply an integrated liquid hydrogen storage and fuel delivery system for a green hydrogen long-duration energy storage system (BH-ESS) in California, according to a news release.
The system will be used in conjunction with a utility-scale battery to provide back-up power to the city of Calistoga.
Chart’s integrated fuel system includes liquid hydrogen (LH2) bulk storage tanks and vaporization equipment used to store the liquid hydrogen on-site and feed to the fuel cells in Energy Vault’s system to power the city,” the release states. “The 80,000-gallon LH2 storage tanks allow for at least 48 hours of site autonomy without refueling.”
The hydrogen fuel cell will be powered by electrolytic hydrogen derived from renewables to serve the local utility Pacific Gas and Electric Company (PG&E), a subsidiary of PG&E Corporation.
