Delivering 50% Performance Gains at Half the Cost for Thermal Energy Storage

Next-generation bGen ONE™ technology delivers 50% performance increase through innovative heating concept and improved system design that enables higher operating temperatures and enhanced efficiency, launching in 2026

Technology Roadmap 2030 outlines continuous innovation with new systems every 12-18 months through 2030, reducing costs by 50-60% and increasing storage media temperature from 600°C to 1500°C

Global pipeline of commercial opportunities exceeds half-billion dollars with 103 MWh in cumulative projects deployed, establishing Brenmiller as an industry leader in thermal energy storage

TEL AVIV, Israel, April 23, 2025–(BUSINESS WIRE)–Brenmiller Energy Ltd. (“Brenmiller”, “Brenmiller Energy” or the “Company”) (Nasdaq: BNRG), a leading global energy provider of thermal energy storage (“TES”) solutions to industrial and utility markets, today announced its Technology Roadmap 2030, highlighting breakthrough innovations that will dramatically improve performance while reducing costs for customers worldwide.

The roadmap builds upon the success of Brenmiller’s commercially available bGen ZERO™ platform and centers on the upcoming launch of bGen ONE™, Brenmiller’s next-generation thermal battery, scheduled for commercial release in 2026. This revolutionary system features a proprietary new heating concept, delivering an over 50% performance improvement, an advanced heat storage design with significantly higher capacity, and enhanced economics that benefit both Brenmiller and its customers. This innovation builds on the Company’s February announcement of the bGen ZERO™ Thermal Oil (bGen ZTO™) system, which addresses an additional $8 billion market opportunity by electrifying thermal oil processes.

“As the most experienced thermal battery developer on the market, we continue to pioneer zero-emissions energy storage solutions that set industry standards,” said Avi Brenmiller, Chairman and Chief Executive Officer of Brenmiller Energy. “Our latest breakthroughs will not only increase battery performance by over 50%, but also improve project margins and economics for our growing ecosystem of customers and partners – ultimately supporting the transition to zero carbon emissions, while delivering superior cost performance compared to fossil fuel-based systems.”

Ambitious Development Timeline

Brenmiller’s technology strategy includes the release of continuously improved bGen™ systems every 12-18 months through 2030, projected 50-60% decrease in system costs through implementation of next-generation heat storage media, increase in thermal storage temperature from a current 600°C to 1500°C, and manufacturing efficiencies through economies of scale and increased pre-fabrication.

Story Continues

The Company’s innovative bGen™ ZERO platform harnesses crushed rocks for high-temperature thermal energy storage, providing a commercially available foundation for these technological advances. Powered by renewable energy, the system generates carbon-free heat, steam, or hot air, ensuring stable conditions for 24/7 operation while remaining cost-competitive with natural gas. It represents a mature, market-ready solution that achieves cost parity with conventional natural gas systems. Beyond delivering reliable thermal energy storage, this innovative platform provides essential grid-stabilization services that accelerate renewable energy adoption by offering the flexibility and balancing capabilities critical for utility-scale renewable integration.

Commercial Momentum

With 103 MWh in cumulative projects deployed, Brenmiller has established itself as an industry leader in thermal energy storage. The Company’s total commercial opportunity pipeline exceeds half a billion dollars, with eight projects valued at approximately $170 million specifically for the new bGen ZTO™ system currently under development.

The bGen ZTO™ system, specially designed for the thermal oil market and currently under development, represents a breakthrough innovation in thermal oil heating, combining internal electric conversion for storage with integrated heat exchange to achieve nearly 100% cycle efficiency. This modular TES system offers simplified maintenance, indirect oil heating with minimal degradation, smooth stability, and the ability to heat thermal oil up to 340°C.
