Plug Power said that it will supply Energy Vault with 8 MW of hydrogen fuel cell stationary power to deliver clean energy to the city of Calistoga, California, during times of wildfires and other emergencies.
Plug (PLUG) said it will be the largest planned hydrogen powered fuel cell installation in the U.S.
Energy Vault (NRGV) typically has rented mobile diesel generators to provide backup power in Calistoga during Public Safety Power Shutoff events, but Plug (PLUG) said its PEM fuel cells will be able to provide cleaner, more operationally flexible, and more cost-effective power to the microgrid.
Energy Vault (NRGV) will own, operate and maintain the energy storage system while providing dispatchable power under a long-term tolling agreement with PG&E (PCG).
Construction of the Calistoga energy storage system is expected to begin in Q4 with commercial operation expected by Q3 2024.
