Halotechnics – Molten Glass Thermal Storage Could Mean 6 Cent Solar

Halotechnics – Molten Glass Thermal Storage Could Mean 6 Cent Solar

Halotechnics , an early-stage solar-thermal startup and ARPA-E recipient, has developed two radical new materials for storing solar heat energy, using new kinds of salts and even a new kind of glass. These allow much higher temperatures than have been used to date to store the heat in solar thermal power plants so they can produce power at night. This will greatly improve the efficiency and lower the costs for solar thermal power. This is a first. While practically every other day we hear about efficiency innovations that will lower the costs of PV solar, this is a major innovation for solar thermal. Unlike solar PV which makes electricity directly, solar thermal makes heat that runs turbines driven by steam. So, unlike solar PV, it has the potential for night time solar generation, because thermal is steam-turbine-driven energy, so it can store the days heat in molten sal...
