247Solar, Inc., a spinoff of MIT, was formed in 2015 by solar industry pioneer Bruce Anderson to commercialise the 247Solar Plant™, 247Solar Thermal Storage™, and related technologies. 247Solar Plants are a turnkey solution for producing baseload, clean electricity around the clock. They eliminate most disadvantages of conventional CSP, PV, wind, and traditional power technologies with a hot-air-driven Brayton Cycle system that operates at atmospheric pressure and requires no steam, molten salts, or heat transfer oils. The 247Solar Thermal Storage System stores up to 20 hours of the sun’s energy as heat instead of electricity, using small ceramic pellets instead of molten salts for reduced cost and complexity. When combined with PV and batteries, 247Solar Microgrids™ can reduce fuel costs relative to diesel gensets by up to 90%.
