About
Brenmiller Energy provides thermal energy storage (TES) solutions designed to decarbonize industrial heat, which accounts for a significant portion of global energy consumption. The company’s core technology, bGen, is a solid-state thermal battery that utilizes crushed rocks as a high-temperature storage medium. This non-toxic, abundant material can be heated up to 750°C using multiple sources, including renewable electricity from solar and wind, off-peak grid power, or industrial waste heat. The stored energy is then discharged on demand as clean steam, hot water, or hot air to power industrial processes or drive steam turbines.
The bGen system is modular and scalable, featuring a three-in-one design that integrates a heat exchanger, storage medium, and steam generator into a single unit. This architecture allows industrial and utility customers to replace fossil-fuel-burning boilers with a carbon-free alternative that achieves cost parity with natural gas. Through its "Heat-as-a-Service" model and the BNRG360 platform, Brenmiller enables clients to transition to sustainable heat production without upfront capital expenditure. By bridging the gap between intermittent renewable energy and the continuous demand of industrial production, the platform provides grid stabilization and ensures 24/7 operational reliability
