Brenmiller Energy Targets Industrial Decarbonization with Thermal Energy Storage and Energy-as-a-Service Model

Industrial heat generation accounts for approximately 10% of global greenhouse gas emissions, surpassing the combined emissions from all cars, planes, and ships. Despite this significant environmental impact, the transition to cleaner industrial heat has lagged behind other sectors. Electrification, while a green alternative, faces challenges such as grid capacity constraints, high electricity costs, and difficulty reaching ultra-high temperatures consistently. Meanwhile, traditional fossil fuel combustion remains a fallback, but regulatory pressures and corporate sustainability goals are pushing for change.

Thermal energy storage (TES) technology is emerging as a solution, and Brenmiller Energy Ltd. (NASDAQ: BNRG) is positioning itself at the forefront. The Israeli company has developed the bGen TES platform, a patented solid-state heat battery that uses crushed volcanic rock to store low-cost renewable electricity as high-temperature heat. This heat can be released on demand as zero-emission steam, hot water, or air, providing industrial customers with a reliable, around-the-clock heat source without relying on critical battery metals.

To address the upfront capital costs that often deter adoption, Brenmiller recently introduced BNRG360, an energy-as-a-service model. Under this approach, Brenmiller develops, owns, and operates the integrated clean energy systems, allowing customers to avoid significant initial investment. Instead, they enter long-term service agreements, paying for heat and power delivered from assets that combine Brenmiller's TES technology with renewable generation and battery storage. This strategic shift from equipment supplier to integrated energy infrastructure company is designed to generate recurring revenues and deepen customer relationships.

The TES market is projected to grow significantly, driven by rising electricity consumption, industrial electrification, grid modernization, and increasing renewable energy penetration. According to forecasts, the market could reach nearly $14 billion by 2032, growing at a CAGR of 10%. Additional demand from artificial intelligence and data center expansion is also expected to boost the need for flexible energy systems.

Brenmiller is already proving its technology in the field. A key project with Tempo Beverages Ltd. involves a 32-megawatt-hour TES installation that supplies continuous industrial process steam, fully replacing the site's fossil fuel boiler-based heat production. The system, which began delivering steam in June 2026, is expected to eliminate approximately 6,200 tons of CO₂ emissions annually. Brenmiller views this as a flagship commercial reference that demonstrates scalability under real-world conditions and serves as a blueprint for future deployments.

Looking ahead, Brenmiller focuses on growth, cash flow improvement, and achieving sustainable profitability. With the BNRG360 platform attracting more customers and additional project commissionings on the horizon, the company is confident in its ability to capitalize on the greening of industrial heat. The industrial market's need for alternative energy sources aligns with Brenmiller's TES solution, positioning it to help companies decarbonize while capturing long-term value.
