Proven Thermal Energy Storage. Engineered for Impact.
More than a decade of thermal energy storage development, proven across industrial and utility deployments.
Charge. Store. Dispatch.
The bGen™ system is a solid-state thermal energy storage (TES) solution engineered for high efficiency and durability.
At the core of our solution is a 10-ton rectangular latent heat module that is filled with crushed rocks as the storage medium – an abundant, stable, and non-toxic material capable of withstanding unlimited thermal cycling at temperatures up to 650°C (1200°F).
Charging directly from renewables or the grid – this energy is converted to heat via embedded electric heaters and stored within an insulated steel vessel. When needed, bGen™ discharges this energy as high-temperature steam, hot air, or thermal oil, offering flexible heat delivery tailored to industrial processes. The system’s modular architecture supports scalable deployment across a wide range of capacities, while its minimal moving parts are designed to ensure low maintenance and long operational life. With fast response times and built-in controls for load shifting and demand management, bGen™ is not just a heat source – it’s a precision-engineered backbone for clean energy infrastructure.
How We Build a bGen™ System
A bGen™ installation is configured around the customer’s heat demand, operating profile and available electricity supply. Modular storage units, electric charging, heat exchangers, process integration and digital controls are engineered as one operating system.
Powered by bGen™
Transforming electricity into dispatchable industrial heat, the foundation that lets BrenX optimize electricity and heat together. Energy can be charged when renewable production is available or electricity prices are favorable, stored safely as heat and dispatched when the industrial process needs it.
Generation Flexibility. Operational Flexibility.
Consume, generate, store and shift energy according to cost, availability, reliability and carbon intensity. Bi-directional optimization supports predictable energy pricing for industry while creating valuable flexibility for the grid.
Complete Energy Freedom
Designed for demanding industrial environments, bGen™ integrates with renewable energy systems, energy services, battery storage, and intelligent grid optimization and is designed to improve efficiency, increase flexibility, reduce emissions, and lower total energy costs.
One partner for clean electricity and industrial heat: built, owned, operated and optimized end to end.
