Brenmiller Energy Disrupts Industrial Heat with Thermal Storage

Industrial heat generation accounts for approximately 10% of global greenhouse gas emissions, surpassing the combined pollution from all cars, planes, and ships. While electrification is often touted as the green solution, it faces challenges like grid capacity limits, high costs, and difficulty reaching ultra-high temperatures consistently. Thermal energy storage (TES) offers a promising alternative, and Brenmiller Energy Ltd. (NASDAQ: BNRG) is emerging as a leader in this space with its bGen TES platform. The patented solid-state heat battery 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 low and use stored energy during peak demand.

To reduce upfront costs, Brenmiller recently introduced BNRG360, an energy-as-a-service model where the company develops, owns, and operates clean energy systems, allowing customers to adopt TES without significant capital investment. This strategic shift from equipment supplier to integrated energy infrastructure provider is designed to generate recurring revenues and deepen customer relationships. The TES market is projected to grow at a CAGR of 10% through 2032, reaching nearly $14 billion, driven by rising electricity consumption, industrial electrification, grid modernization, and AI data center expansion.

Brenmiller is already proving its technology in real-world applications, notably with Tempo Beverages Ltd., where a 32-megawatt-hour TES installation replaces fossil fuel boilers, eliminating approximately 6,200 tons of CO₂ emissions annually. This project serves as a blueprint for industrial decarbonization. With additional partnerships and the BNRG360 platform, Brenmiller aims to achieve sustainable profitability and capture significant long-term value.
