Industrial heat generation accounts for about 10% of global greenhouse gas emissions, surpassing the combined emissions from all cars, planes, and ships. Yet, the decarbonization of industrial heat has received relatively little attention compared to other sectors. Traditional methods rely on burning fossil fuels, while electrification faces challenges such as grid constraints, high costs, and difficulty achieving ultra-high temperatures.
Brenmiller Energy Ltd. (NASDAQ: BNRG) is emerging as a key player in addressing this challenge through its thermal energy storage (TES) technology. The company's bGen platform uses crushed volcanic rock to store renewable electricity as high-temperature heat, which can be released on demand as zero-emission steam, hot water, or air. By avoiding critical battery metals and enabling charging during low-cost periods, the system offers a practical solution for industrial customers requiring reliable, round-the-clock heat.
To reduce upfront costs, Brenmiller recently introduced BNRG360, an energy-as-a-service model. Under this approach, Brenmiller develops, owns, and operates the clean energy systems, allowing customers to adopt TES without significant capital investment. This strategic shift from equipment supplier to integrated energy infrastructure company is designed to generate recurring revenues and deepen customer relationships through long-term service agreements.
The TES market is projected to grow at a compound annual growth rate of 10%, reaching nearly $14 billion by 2032, driven by rising electricity consumption, industrial electrification, grid modernization, and the expansion of AI and data centers. Brenmiller's technology is already being deployed at scale with Tempo Beverages Ltd., a 32-megawatt-hour installation that supplies continuous industrial process steam, replacing a fossil fuel boiler and eliminating approximately 6,200 tons of CO₂ emissions annually. The system began delivering steam in June 2026 and is expected to serve as a blueprint for future industrial decarbonization projects.
With its bGen platform and BNRG360 model, Brenmiller is positioning itself to capitalize on the greening of industrial heat. The company is in discussions with other potential customers and aims to achieve growth, positive cash flow, and sustainable profitability as more projects come online.
