Brenmiller Energy Ltd. announced today the commencement of development for its bGen ZERO Thermal Oil™ (bGen ZTO) system, designed to electrify thermal oil for industrial applications. This new system is planned for commercial availability in 2026.

The bGen ZTO expands Brenmiller’s total addressable market into the $8 billion annual thermal oil heating equipment market, which is growing at a compound annual growth rate of 6%. Thermal oil is used in industries such as pharmaceuticals, chemicals, petrochemicals, and food processing, with 95% currently powered by fossil fuels.

Brenmiller has already identified 8 projects worth approximately $170 million in its commercial pipeline for the bGen ZTO. This breakthrough innovation is a modular TES system that will combine internal electric conversion for storage with integrated heat exchange, aiming for nearly 100% cycle efficiency and heating thermal oil up to 340°C.
