Business overview

Brenmiller Energy specializes in thermal energy storage (TES) solutions aimed at decarbonizing industrial heat, a major contributor to global energy consumption. Its core technology, bGen, is a solid-state thermal battery that uses crushed rocks to store heat up to 750°C. This system can be charged using renewable electricity, off-peak grid power, or industrial waste heat, then discharged as clean steam, hot water, or hot air for industrial processes or steam turbines. The modular bGen system integrates a heat exchanger, storage medium, and steam generator, enabling industrial and utility clients to replace fossil-fuel boilers with a carbon-free alternative that achieves cost parity with natural gas. Through its "Heat-as-a-Service" model and BNRG360 platform, Brenmiller Energy serves industrial and utility markets, providing sustainable heat production, grid stabilization, and operational reliability.

Strategic signal

In September 2025, Brenmiller Energy signed a system purchase agreement with Baran Energy for bGen ZERO Systems at Tempo Beverages and Wolfson Medical Center, with revenue generation expected to begin in 2026. This signals strong commercial traction and market validation for Brenmiller's thermal energy storage solutions, indicating a clear path to revenue growth and wider adoption of its decarbonization technology in industrial applications.
