Industrial heat generation accounts for about 10% of global greenhouse gas emissions, surpassing the combined emissions of all cars, planes, and ships. Yet efforts to decarbonize sectors like steel, cement, and glass production have largely overlooked this significant source of pollution. Electrification, the primary green alternative, faces challenges including grid constraints, high electricity costs, and difficulty reaching ultra-high temperatures consistently. Brenmiller Energy Ltd. (NASDAQ: BNRG) is emerging as a trailblazer in thermal energy storage (TES) technology, offering a solution that promises to overcome these limitations.
The company's 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 directly addresses the intermittency of renewables and the high cost of peak electricity, making industrial decarbonization more economically viable.
To further reduce barriers to adoption, Brenmiller recently introduced BNRG360, its energy-as-a-service model. Under this offering, Brenmiller develops, owns, and operates the integrated clean energy systems, eliminating upfront capital costs for customers. The company evolves from an equipment supplier to an integrated energy infrastructure company, generating recurring revenues through long-term service agreements. This strategic shift is designed to deepen customer relationships and capture greater long-term value as the installed base of operating projects grows.
The global TES market is projected to reach nearly $14 billion by 2032, growing at a CAGR of 10%, driven by rising electricity consumption, industrial electrification, grid modernization, and increasing renewable energy penetration. The expansion of AI and data centers further strains electrical infrastructure, heightening the need for flexible energy systems like TES.
Brenmiller's technology is already being demonstrated at scale. At Tempo Beverages Ltd., a 32-megawatt-hour TES installation is supplying 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 in June. This project represents the culmination of over 15 years of technology development and serves as a blueprint for future industrial decarbonization deployments worldwide. The operational experience and performance data from Tempo are expected to strengthen customer confidence and support future commercial opportunities.
Looking ahead, Brenmiller is focused on growth, boosting cash flow, and achieving sustainable profitability. With additional customers expected to join the BNRG360 platform and more successful project commissionings on the horizon, the company is confident in its ability to capitalize on the multi-billion-dollar opportunity in industrial heat decarbonization. As governments and businesses continue investing in decarbonization, thermal energy storage demand is expected to increase, positioning Brenmiller at the forefront of this critical transition.
