About the Company 

247Solar provides the first complete application of high-temperature, modular solar power with overnight storage—now delivered as a turnkey solution for clean industrial process heat and baseload renewable electricity, on a PPA basis.

About the Solution

247Solar’s flagship offering, the 247Solar Plant™, integrates three novel subsystems into a unified, dispatchable clean energy platform. The solar receiver concentrates sunlight to heat ambient-pressure air up to ~970 °C, enabling high efficiency in a compact footprint. Excess energy, whether from solar, wind, or the grid, is converted into heat and stored in inexpensive media (e.g. ceramic pellets) using our HeatStorE™ system, which can deliver between 4 to 20+ hours of storage. When dispatch is required, hot air is routed through our Heat2Power™ turbine, generating electricity without combustion or emissions in its standard mode. If storage is depleted, the turbine can seamlessly burn backup fuels, including hydrogen or biofuels, to maintain full output and guarantee continuous service. Because the turbine exhaust remains hot (≈ 250 °C), that thermal energy can be reused for industrial processes (drying, steam, absorption cooling, water purification).
