Power Generation

A dispatchable, grid-scale thermal energy storage system based on a molten silicon storage medium. Excess electricity is converted to thermal energy to heat the silicon, stored in one of two large tanks. When demand arises, glowing-hot molten silicon is pumped through an array tubes that emit light, and special-purpose multi-junction photovoltaics convert the generated light to electricity.

SolarWindow's organic photovoltaic arrays (OPVs) modules are created by applying ultra-thin liquid polymer coatings to glass and flexible plastics. The modules can

The Brayton Energy team will develop an energy storage system that combines thermal storage and a gas turbine to generate power. When the system is charging, an electrically driven heat pump will accumulate thermal energy in a molten salt solution, which can then be discharged later by heating gas and sending it through the generation turbine. Brayton Energy’s innovation lies in their reversible turbine design, in which each turbine acts as the compression stage for the other, whether during charging or discharging. This approach simplifies the system and increases durability.
