Brenmiller Energy Ltd is an Israeli clean technology company specializing in thermal energy storage solutions for industrial and power generation applications. Headquartered in Rosh Ha'ayin, Israel, Brenmiller has developed its bGen thermal energy storage system, which stores heat in crushed rocks at high temperatures and releases it on demand. This technology enables renewable energy integration, waste heat recovery, electrification of industrial heat processes, and replacement of fossil fuels in industries requiring process heat. Brenmiller's solutions address critical needs in decarbonizing industrial sectors and enabling higher penetration of intermittent renewable energy. The bGen system stores thermal energy by heating crushed rocks to temperatures up to 750°C using electricity (potentially from renewable sources during low-cost periods) or waste heat from industrial processes. The stored heat is then released as steam or hot air when needed for industrial processes, power generation, or other applications. This thermal battery approach offers advantages including long discharge duration (hours to days), high energy density, use of abundant low-cost materials (rocks), long operational lifetime, and safety compared to chemical batteries. Brenmiller's technology serves industries including food and beverage, chemicals, pharmaceuticals, textiles, and others requiring process steam or heat. The company targets the massive industrial heat market, which accounts for significant global energy consumption and CO2 emissions. Thermal energy storage enables industries to shift energy use to off-peak hours, integrate renewable energy, recover and reuse waste heat, and reduce fossil fuel consumption. Brenmiller has secured pilot projects and commercial contracts with industrial customers and utilities. The company competes with other thermal storage technologies, battery storage providers, and traditional fossil fuel-based systems. Success depends on demonstrating reliable performance, achieving favorable economics versus alternatives, securing project financing, building reference installations, navigating evolving incentive programs for decarbonization, and scaling manufacturing. The thermal energy storage market is growing with increasing focus on industrial decarbonization, but faces challenges including long sales cycles, project complexity, customer conservatism, and need for customer education about emerging technologies.
