Energy Vault's CRC project is utilizing a hybrid approach by combining hydrogen fuel cells with a lithium-ion battery energy storage system to enhance power resiliency in Calistoga, California. The project aims to provide continuous energy for up to 48 hours during public safety power shutoff events, ensuring the Calistoga community microgrid's operation during grid disconnections. By operating in 'island' mode and utilizing green hydrogen, the system can generate electricity independently. Energy Vault's innovative CRC, which recently achieved mechanical completion, is set to commence full commercial operations in Q2 2025. The project is expected to serve as a model for future utility-scale hybrid microgrid storage deployments across wildfire-prone regions, addressing power resiliency challenges. Energy Vault's strategic shift towards battery energy storage systems alongside its gravity-based long-duration energy storage technology is highlighted by the company's ownership and management of projects like the 57MW/114MWh BESS in Texas. While there have been discussions regarding the transportation of green hydrogen instead of on-site electrolysis, the project showcases Energy Vault's commitment to sustainable and resilient energy solutions.
