A new micro-grid storage tank has been delivered to Calistoga, California, for the Calistoga Resiliency Center, a project led by Energy Vault Holdings, Inc. for Pacific Gas and Electric Company. The center, located on less than one acre of land, will be the largest utility-scale green hydrogen energy storage project in the United States upon completion. The system aims to provide up to 48 hours of continuous power during potential Public Safety Power Shutoffs, enhancing grid resiliency in the area. The initiative represents a shift towards cleaner microgrid generation, aiming to replace traditional diesel generators with a more sustainable solution leveraging a combination of green hydrogen and batteries. Energy Vault will operate and maintain the energy storage system under a long-term agreement with PG&E, contributing to PG&E's goal of achieving a net zero energy system by 2040. The project has been designed to optimize grid resiliency, leverage multiple technologies, and provide cleaner, more reliable backup power to enable islanded microgrids during transmission outages.
