In a significant move towards sustainable energy solutions, Energy Vault Holdings has selected Chart Industries to implement an integrated liquid hydrogen storage and fuel delivery system. Set to be the largest in the United States, this system has the potential to revolutionize the utility-scale energy storage landscape as it forms part of a long-duration, green hydrogen energy storage project. Showcasing the potential for collaborative innovation in the green energy sector, Chart Industries will collaborate with Avinash Clean Hydrogen on this groundbreaking hydrogen project in Southern California. Chart Industries is also breaking new ground in setting an ambitious timeline for such advanced green energy projects. The state-of-the-art plant, equipped with Howden compressors supplied by Chart Industries, is expected to be fully operational by mid-2024.

This hydrogen plant offers an innovative solution to a significant source of carbon emissions by utilizing gaseous hydrogen to decarbonize heavy-duty trucks in California. This project aligns with state policy aimed at encouraging innovative clean energy initiatives, a response to California Governor Gavin Newsom’s 2020 executive order to prohibit the sale of diesel or gasoline-powered vehicles by 2035. Embodying the immense potential of hydrogen in advancing energy transitions, this project supports California in its ambition to reduce greenhouse gas emissions by 85% by 2045. Jill Evanko, the President & CEO of Chart Industries, has emphasized the company’s proficiency in developing hydrogen solutions, hinting at potential future innovations in the sector.

In 2023, Plug Power committed to supply Avina Clean Hydrogen with containerized proton exchange membrane electrolyzers, signifying a growing market for advanced hydrogen production technologies. These electrolyzer units, capable of producing up to 2 metric tonnes of green hydrogen per day, demonstrate a substantial capacity for clean energy production. Energy Vault acknowledged Chart’s expertise in innovative liquid hydrogen storage solutions, underlining the importance of this emerging field within the hydrogen energy market. Construction for this pioneering project, marking a rapid progression towards large-scale hydrogen energy storage, is set to begin in Q4 2023.

The project highlights the potential of hydrogen energy in strengthening grid resilience to meet increasing demand, as it will provide backup power to the city of Calistoga, California. Chart’s integrated fuel system, designed to provide at least 48 hours of site autonomy, features 80,000-gallon liquid hydrogen storage tanks and vaporization equipment, illustrating the potential for hydrogen storage to ensure grid stability. Energy Vault’s system, set to replace mobile diesel generators typically used by PG&E during grid outages, underscores the importance of green energy in creating a more reliable and sustainable grid. This project thus represents a significant stride towards achieving the California Public Utilities Commission’s vision of cleaner microgrid generation, showcasing the transformative potential of such initiatives.
