Generating industrial heat produces about 10% of global greenhouse gas emissions, surpassing the pollutants from all the world's cars, planes and ships combined, yet efforts to decarbonize this sector have lagged. Brenmiller Energy Ltd. (NASDAQ: BNRG), an Israel-based thermal energy storage (TES) provider, is aiming to fill that gap with its bGen platform and a new service model called BNRG360.
The bGen platform is a patented solid-state heat battery that uses crushed volcanic rock to store low-cost renewable electricity as high-temperature heat, releasing it on demand as zero-emission steam, hot water, or air. By utilizing abundant materials instead of critical battery metals, customers can charge the system when electricity prices are lower and use stored energy during periods of higher demand. This approach addresses shortcomings of full electrification, such as grid capacity constraints and high electricity costs, while providing a cleaner alternative to burning fossil fuels.
To eliminate upfront costs, Brenmiller recently introduced BNRG360, an energy-as-a-service model. Under this model, Brenmiller develops, owns, and operates integrated clean energy systems, allowing customers to adopt TES without significant capital investment. The company describes BNRG360 as a strategic evolution from equipment supplier to integrated energy infrastructure company, designed to generate recurring revenues and deepen customer relationships through long-term service agreements.
The need for TES is expected to grow significantly, driven by rising electricity consumption, industrial electrification, grid modernization, increasing renewable energy penetration, and growing attention to energy security. Additionally, the expansion of artificial intelligence and data centers is placing further demands on electrical infrastructure. One forecast projects the TES market to grow at a CAGR of 10% through 2032, reaching nearly $14 billion.
Brenmiller has moved beyond the concept stage with a key partnership at Tempo Beverages Ltd. The 32-megawatt-hour TES installation is engineered to supply continuous industrial process steam, fully replacing the site's fossil fuel boiler-based heat production. The system is expected to eliminate approximately 6,200 tons of CO₂ emissions annually and began delivering steam power in June. Brenmiller said Tempo is expected to become one of its most significant commercial reference installations, serving as a blueprint for future industrial decarbonization deployments worldwide.
The operational experience and performance data from Tempo will strengthen customer confidence and support future commercial opportunities, the company stated. In addition to Tempo, Brenmiller is in discussions with other companies about decarbonization projects. Looking ahead, the company's focus is on growth, boosting cash flow, and achieving sustainable profitability, with more customers expected to join its BNRG360 platform.
As industrial companies face pressure to lower carbon emissions, Brenmiller's TES technology offers a path to decarbonize industrial heat without compromising reliability or cost. The company's shift to an energy-as-a-service model also reduces financial barriers, potentially accelerating adoption across industries such as steel, cement, and glass manufacturing.
