Brenmiller Energy is an Israeli company that makes and sells thermal energy storage (TES) systems for industrial and power generation customers. Its core product, the bGen™ system, stores heat in crushed rocks at temperatures up to 760°C and dispatches that heat on demand as steam, hot air, or hot water. Industrial customers — in food and beverage, chemicals, pharma, paper, and other heat-intensive sectors — use bGen™ to replace fossil fuel boilers with electrically-powered heat. Power plant operators use it to add storage capacity alongside renewable generation. Brenmiller sells systems through direct sales, regional distributors, and a European joint venture covering Spain, Hungary, Germany, and Portugal, with a separate U.S. distribution agreement covering the northeastern states. Brenmiller generates revenue through two main models: direct equipment sale (with recurring maintenance and warranty revenue after installation) and Energy as a Service (EaaS), where Brenmiller owns, operates, and finances the system on-site and sells the thermal output to customers under long-term contracts, typically with a customer option to buy out the system at contract end. The company manufactures systems at its Dimona, Israel factory, which is designed for 1 GWh annual capacity and built to scale to 4 GWh. Brenmiller is pre-profitability and has funded operations through equity issuances, government grants, and debt.
