BrenX Ltd. is the commercial evolution of Brenmiller Energy, a Nasdaq-listed company that builds on nearly fifteen years of thermal energy storage development. Press releases on its site are datelined Dimona, Israel. In July 2026 it introduced the BrenX long-term plan to move from storage technology to integrated industrial energy infrastructure.

Its core product, bGen, is a proprietary thermal energy storage system that turns electricity and recovered heat into dispatchable heat as steam, hot water, hot air or thermal oil. Listed project references include TEMPO (Israel, 32 MWh), a 24 MWh pilot with ENEL (Italy), Wolfson Hospital (Israel, 12 MWh) and PPF (Hungary, 30 MWh).

• bGen storage: proprietary thermal storage manufactured industrially.
• Multiple outputs: steam, hot water, hot air and thermal oil.
• Heat recovery: uses recovered heat as well as electricity as input.
• Project references: TEMPO, Wolfson Hospital, ENEL pilot and PPF.
• Integrated platform: BrenX adds generation, flexible assets and digital optimisation.

Steam supply for beverage and food plants replacing gas boilers. Hot water and steam for hospitals and hotels. Process heat for industrial parks combining solar power and recovered heat.

Delivers dispatchable heat in four forms: steam, hot water, hot air and thermal oil.

Combines storage with renewable electricity and recovered heat.

References range from 12 MWh to 32 MWh industrial and hospital projects.

Integrated platform adds power and digital optimisation.

Electrification of industrial heat is a growing segment as plants seek alternatives to gas boilers. Thermal storage lets heat users buy power at low-price hours. Food, beverage and manufacturing sites in Vietnam and ASEAN face rising fuel costs and customer decarbonisation requirements.
