Industrial heat production accounts for roughly 10% of global greenhouse gas emissions—more than all the world's cars, planes and ships combined. Yet efforts to decarbonize sectors such as steel, cement and glass have largely overlooked process heat, according to industry data. Brenmiller Energy Ltd. (NASDAQ: BNRG), an Israel-based thermal energy storage (TES) provider, is seeking to fill that gap with its bGen platform and a newly introduced energy-as-a-service model called BNRG360.
The bGen system is a patented solid-state heat battery that uses crushed volcanic rock to store low-cost renewable electricity as high-temperature heat. It releases that heat on demand as zero-emission steam, hot water or air. By relying on abundant materials rather than critical battery metals, the company says the technology can help industrial customers charge when electricity prices are low and discharge during periods of higher demand or cost.
To lower adoption barriers, Brenmiller recently launched BNRG360, an energy-as-a-service offering under which the company develops, owns and operates integrated clean energy systems. Customers avoid upfront capital expenditure and instead pay for heat and power through long-term service agreements. The shift from equipment supplier to integrated energy infrastructure company is designed to generate recurring revenue, deepen customer relationships and capture greater long-term value over each project’s lifecycle, Brenmiller said.
The strategic move could reshape how investors evaluate the business as the installed base of operating projects grows, the company noted. The global TES market is projected to expand at a compound annual growth rate of 10% between now and 2032, reaching nearly $14 billion, according to one forecast cited by Brenmiller. Driving factors include rising electricity consumption, industrial electrification, grid modernization, increasing renewable energy penetration and growing attention to energy security. The expansion of artificial intelligence and data centers is also adding pressure on electrical infrastructure, creating demand for more flexible energy systems.
Brenmiller is proving its technology in a real-world setting with Tempo Beverages Ltd. The 32-megawatt-hour TES installation is designed to supply continuous industrial process steam and fully replace the site’s fossil fuel boiler-based heat production. The system has already started delivering steam as of June and is expected to eliminate approximately 6,200 tons of CO₂ emissions annually. Brenmiller said the Tempo project is expected to become one of its most significant commercial reference installations, demonstrating the company’s ability to deploy TES at industrial scale under real-world operating conditions. The project represents the culmination of more than 15 years of technology development and is intended to serve as a blueprint for future industrial decarbonization deployments worldwide.
Operational experience and performance data from Tempo is expected to strengthen customer confidence and support future commercial opportunities, Brenmiller added. The company said it is in discussions with other companies about decarbonization projects using its platform.
Looking ahead, Brenmiller said its focus is on growth, boosting cash flow and achieving sustainable profitability. With more customers expected to join the BNRG360 platform and additional project commissionings on the horizon, the company is confident it can achieve those milestones. As industrial heat continues to represent a significant source of global emissions, thermal energy storage may offer a viable alternative to fossil fuels, and Brenmiller is positioning itself to help companies decarbonize with its bGen platform.
