Energy Vault Begins Construction of the Largest Green Hydrogen Long Duration Energy Storage System in the U.S. - Seite 2

“Deploying cost-effective, next-generation energy supply and long-term storage technologies is essential to ensuring grid reliability and to achieving PG&E’s goal of a net zero energy system by 2040,” said Mike Delaney, Vice President, Utility Partnerships and Innovation. “PG&E is developing a portfolio of promising new forms of electricity generation and storage technologies, and identifying the right applications that will support the further proliferation of these technologies at the lowest capital cost and highest-impact locations.”

The energy storage system will be owned, operated and maintained by Energy Vault while providing dispatchable power under a long-term tolling agreement with PG&E. The Company will leverage its VaultOS Energy Management System to control, manage and optimize the BH-ESS operations. The system has been developed under the umbrella of Energy Vault’s H-VAULT suite of hybrid configurations leveraging green hydrogen and batteries, to ensure continuity and resilience during PSPS events. By coupling the ultra-long duration capabilities of fuel cells using green hydrogen, and the fast response capabilities of B-VAULT️ lithium-ion batteries, H-VAULT provides the clean, reliable, cost-effective back-up power that is critical to enable islanded microgrids during transmission outages.

Under the 10.5-year agreement, Energy Vault will provide “Distributed Generation-Enabled Microgrid Services” – a type of energy service that involves using grid-forming generation and storage resources, to provide energy, fault current contribution and to regulate voltage and frequency within the utility’s established parameters to enable the islanding of the Calistoga microgrid during PSPS outages. The solution is designed to operate during PSPS events, serving all the load within a safe-to-energize area in the City of Calistoga, including critical facilities such as fire and police stations, and shared services in the downtown and surrounding area.
