TEL AVIV, IL AND AURORA, CO / ACCESS Newswire / February 18, 2026 / Brenmiller Energy Ltd. (NASDAQ:BNRG) (“Brenmiller”, “Brenmiller Energy” or the “Company”), a leading provider of thermal energy storage (“TES”) solutions for industrial and utility applications, today announced that Rock Energy Storage (“Rock”), Brenmiller’s exclusive distributor in the Northeastern United States, together with Idaho National Laboratory (“INL”), the U.S. Department of Energy’s lead laboratory for advanced nuclear energy research and small modular reactors (“SMR”) development, will present on the integration of SMRs with TES at the IDEA Campus 2026 conference.

The presentation will address how pairing SMRs with TES can enhance operational flexibility, strengthen economic performance, and accelerate campus and district energy decarbonization strategies.

Enabling Flexible and Resilient Nuclear Based Decarbonization

SMRs are designed to provide steady, carbon-free baseload energy. However, campus and district energy systems operate with variable thermal demand profiles. Integrating TES enables the storage of excess thermal output during low demand periods and dispatch of heat when required, improving overall system efficiency and reducing reliance on fossil fuel backup.

In addition to flexibility and economic benefits, TES can contribute to system level resilience as. TES can function as a thermal buffer or “hot sink,” absorbing excess heat during transient conditions or demand fluctuations. By providing an additional pathway for controlled heat absorption and release, TES can support stable reactor operation and enhance overall system resilience.

Brenmiller’s bGen^™ TES system, based on its proven bCube architecture, stores high temperature heat in crushed rock and delivers saturated or superheated steam or hot air on demand. When integrated with SMRs, TES can enable:

• Flexible thermal dispatch aligned with dynamic campus loads
• Improved reactor utilization by reducing curtailment
• Reduced thermal stress during load transitions
• Lower peak demand exposure and reduced dependence on fossil based peaking assets
• Scalable deployment aligned with phased infrastructure expansion

TES acts as a buffer between continuous nuclear heat generation and fluctuating end use demand, allowing SMR based systems to operate steadily while delivering demand driven thermal output.

“We believe that integrating TES with SMRs a practical way to unlock their full value for campuses and district energy systems,” said Avi Brenmiller, Chairman and Chief Executive Officer of Brenmiller. “SMRs provide stable, carbon free heat. TES adds the flexibility and system level buffering that real world energy users require. Together, they can deliver reliable and cost competitive decarbonization without oversizing generation assets.”

Advancing Campus Energy Resilience

The collaboration between Rock and INL reflects a broader industry effort to align advanced nuclear technologies with proven thermal storage solutions to support resilient, low carbon campus infrastructure.

“Campuses and district energy operators are focused on long term reliability, cost stability, and reduced dependence on fossil fuels,” said Cory Glick, President and Chief Executive Officer of Rock Energy Storage. “Integrating SMRs with thermal energy storage will allow us to align steady nuclear generation with real world thermal demand while strengthening operational independence and economic performance.”

Brenmiller’s TES platform has been deployed and validated in grid connected, power generation, and industrial settings. The Company continues to advance collaborations that position TES as a core enabler of next generation clean heat infrastructure.
