Thermal Energy Storage

Thermal Storage, Heat Exchanger & Steam Generation in One

The bGen unit is charged from different renewable sources: electrical, such as PV, wind, or grid at off-peak; Thermal sources such as biomass, flue-gas, heat recovery, or any combination of these inputs. This energy is captured using electrical heaters and gas piping which runs through the storage modules and transfer its heat to the storage media at high temperature of up to 1400°F. In parallel or hours later, steam is discharged to meet customer’s demand.

Electrical Charging

Electricity from renewable energy sources such as PV, wind or directly from a grid during off-peak hours, when electric rates are low, can be used to charge the bGen.​ The electrical input is converted to high temperature heat using embedded electrical heaters in the storage modules.​ No gases or emissions are produced in this process.​ The system can thermally charge while simultaneously providing steam or hot water, as needed. The system is designed to always maintain a constant steam pressure. Having two independent cycles inside the unit offers full control and flexibility for charging and discharging aligned with your process.

Thermal Charging

Heat recovery, biomass combustion, CHP and other external thermal sources can be used to charge the bGen. Recovered heat is efficiently transferred to the storage media. Stored heat can also be augmented with imbedded electric resistive heating elements providing optimal flexibility to match steam or hot water demands. 

Decarbonize Heat

Generate “Clean and Green” Steam or Hot Water

• Replace fossil fuels and generate clean and carbon-free steam or hot water.
• Waste Heat Recovery  – utilize waste heat from your process or CHP exhaust.
• Utilize off-peak energy, when prices are lowest, to decarbonize your thermal processes.
