Molten Salt May Be Solution to Solar Energy Storage

While adoption of solar energy steps up around the world, two key challenges remain: how to store the energy created during the day so it can be used through the night and how to dispatch the energy to where it is needed. Both of these problems may be solved by coupling molten salt with concentrating solar power (CSP), according to a June 26 article in Renewable Energy World. You will recall from previous CleanTechnica postings that CSP technology concentrates the sun’s power to create steam, which turns a turbine to make electricity. But how did molten salt get into the picture?

“Terry Murphy, Chief Executive Officer for SolarReserve, who along with others helped develop the molten salt technology at Rocketdyne. ‘Molten salt is a heat storage medium that retains thermal energy very effective...
