Energy Vault has successfully closed a $28 million project financing for the Calistoga Resiliency Center in California, a groundbreaking ultra-long duration hybrid green hydrogen energy storage microgrid. The project, developed to address power resiliency challenges during wildfires and Public Safety Power Shutoff events, integrates advanced hydrogen fuel cells with lithium-ion batteries. The microgrid provides 48 hours of continuous energy supply and peak power output of 8.5 MW, utilizing green hydrogen in fuel cells for electricity generation. The system, currently under commissioning, is expected to achieve full commercial operation in Q2 2025. The Calistoga Resiliency Center aligns with California's Renewable Portfolio Standard and meets PG&E's long duration energy storage requirements. Energy Vault's technology-agnostic VaultOS™ Energy Management System orchestrates the entire microgrid, ensuring seamless performance and communication with PG&E's Distribution Control Center. The success of this project marks a milestone in Energy Vault's growth strategy and commitment to sustainable energy solutions. Energy Vault's Chairman and CEO, Robert Piconi, emphasized the importance of the Calistoga Resiliency Center in enhancing energy resilience for communities facing wildfire risks. The project signifies a shift towards innovative and sustainable carbon-free energy solutions, setting a model for future utility-scale deployments. The financing of this center enables Energy Vault to generate predictable and recurring revenue streams while contributing to the safety and energy security of the Calistoga community.
