Business overview

Brenmiller Energy specializes in thermal energy storage (TES) solutions aimed at decarbonizing industrial heat, a significant contributor to global energy consumption. Its core product, bGen, is a solid-state thermal battery that uses crushed rocks to store heat up to 750°C. This system can be charged by renewable electricity, off-peak grid power, or industrial waste heat, and then discharges energy as clean steam, hot water, or hot air for industrial processes or steam turbines. The modular and scalable bGen system integrates a heat exchanger, storage medium, and steam generator, enabling industrial and utility clients to transition to carbon-free heat production at cost parity with natural gas. Through a "Heat-as-a-Service" model and the BNRG360 platform, Brenmiller serves markets by bridging intermittent renewable energy supply with continuous industrial demand, operating within the Energy Tech sector.

Strategic signal

Brenmiller Energy is actively expanding its market reach and product deployment, as evidenced by its system purchase agreement with Baran Energy in September 2025 for bGen ZERO Systems at Tempo Beverages and Wolfson Medical Center. This move signals a strong commercial trajectory and validation of its thermal energy storage technology in real-world industrial applications, indicating potential for significant revenue generation starting in 2026 and reinforcing investor confidence in its growth strategy.
