Cryogenic Energy Storage Innovation Focused on Repowering Peaker Plants

Cryogenic Equipment Services, LLC (CES) is a U.S.-based company focused on advancing liquid air energy storage (LAES) systems designed specifically to repower aging and decommissioned peaker plants across the United States.

CES Energy Storage builds on more than four decades of cryogenic engineering expertise from its parent organization, applying proven industrial air‑separation technology to modern grid-scale energy storage. The company’s patented liquid air energy storage platform is engineered to transform existing peaker plant infrastructure into clean, efficient, long‑duration energy storage facilities capable of delivering dispatchable electricity during periods of peak demand.

Addressing the Challenges of America’s Aging Peaker Plant Fleet

Across the United States, thousands of megawatts of peaker plant capacity remain essential for grid reliability. These facilities were designed to operate only during periods of peak electricity demand, yet many are aging, inefficient, and increasingly subject to environmental regulations.
CES focuses on repowering these legacy facilities using liquid air energy storage rather than building entirely new generation infrastructure. By utilizing existing peaker plant locations, grid interconnections, and electrical equipment, CES enables storage developers and infrastructure investors to modernize critical assets while maintaining the dispatchable power the grid requires.

Engineering Built for Real-World Deployment

Every CES liquid air energy storage system is developed with a constructability-first consideration. The company focuses on practical integration with existing energy infrastructure and emphasizes:

Integration with existing peaker plant sites
Scalable system architecture
Proven cryogenic process technology
Reliable grid-connected power generation
Modular deployment for faster implementation

CES collaborates with storage developers, energy infrastructure developers, investors, and strategic partners across the United States who are seeking a cleaner and more efficient solution for peak power generation.
