Technology

Proven Thermal Energy Storage. Engineered for Impact.

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 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

Machine

The bGen™ system is comprised of multiple, identical prefabricated modules called bCubes™

Wurth

bCubes™ are assembled onsite, then connected one to another to one TES block

TES Unit Italy

TES block is insulated to minimize thermal losses and connected to the plant
