Battery Energy Storage Systems (BESS)

Battery Energy Storage Systems (BESS) are battery-based energy assets that store electricity and discharge it when needed to improve reliability, manage demand, and optimize energy use. While often associated with utility-scale renewable integration, BESS is also widely deployed in industrial facilities, commercial buildings, data centers, and other mission-critical environments. Depending on the application, BESS can support peak shaving, backup power, resiliency, renewable firming, load shifting, and fast-response grid or facility stabilization.

Proven aerogel materials for BESS thermal protection

Aspen’s aerogel products are backed by our patent-protected Aerogel Technology Platform^® and combine proven thermal performance with experience in some of the world’s most demanding industrial and battery applications. For BESS customers, that means materials designed to help control heat, improve fire resilience, and protect critical equipment when thermal events occur.

Pyrogel^® provides high-performance thermal insulation in harsh operating environments and can bring valuable thermal management and passive fire protection benefits to BESS infrastructure and adjacent equipment.

PyroThin^® has been adopted by leading automotive OEMs to help reduce heat transfer during thermal runaway events. That same thermal barrier expertise is highly relevant to BESS, where slowing heat propagation can help protect neighboring components and reduce system-level risk.

Together, these proven materials give BESS developers and operators access to aerogel-based solutions backed by real-world performance in both industrial thermal insulation and advanced battery protection.
