Brenmiller Energy Ltd. (NASDAQ:BNRG) saw its stock climb 12.5% after announcing a non-binding memorandum of understanding with ENASCO Ltd. to jointly develop thermal energy storage solutions integrated with small modular reactors (SMRs).
The partnership aims to merge Brenmiller’s bGen thermal energy storage technology with liquid metal reactor-based SMRs, initially targeting AI data centers as a key market. The companies plan to roll out three commercial-scale projects worth $50 million by 2030, with the first set to launch in 2027.
Long-term ambitions include expanding to 15-20 projects valued at $650 million by 2035. Their roadmap involves strategic alliances with SMR suppliers and pilot integrations at AI data centers starting in 2026.
“In cooperation together with ENASCO, we plan to leverage our complementary capabilities to explore creating a scalable, high-efficiency hybrid platform that answers the energy market’s need for clean and dispatchable baseload power,” said Doron Brenmiller, Chief Business Officer of Brenmiller Energy.
The integrated system is designed to deliver improved passive safety, simplified design, grid flexibility, and scalability from 10 MWh pilot projects up to multi-GWh utility-scale solutions.
Citing a McKinsey report, the companies noted AI data centers are expected to consume nearly 12% of U.S. power demand by 2030. Data from the International Energy Agency projects SMR capacity could reach 120 GW by 2050, requiring more than $670 billion in investment globally.
ENASCO specializes in engineering and consulting for SMR deployments across Europe, while Brenmiller’s bGen system stores energy as heat using crushed rock for industrial applications.
