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 from various sources, including renewable electricity and industrial waste heat. This stored energy is then released as clean steam, hot water, or hot air for industrial processes or power generation. The modular bGen system integrates a heat exchanger, storage medium, and steam generator, offering a carbon-free alternative to fossil-fuel boilers at cost parity with natural gas. Through its "Heat-as-a-Service" model and BNRG360 platform, Brenmiller Energy enables industries and utilities to transition to sustainable heat production, providing grid stabilization and operational reliability by bridging intermittent renewable energy supply with continuous industrial demand. The company operates within the Energy Tech sector, focusing on eco-efficient energy storage and clean industry tech.

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 commence in 2026. This signals strong commercial validation for its thermal energy storage technology and indicates a clear path to revenue, demonstrating the company's ability to secure significant contracts and advance its market penetration in industrial decarbonization.
