SolarReserve has been given permission to build a solar plant that uses molten salt to both collect and store energy. Most solar plants have always had an issue with storing electricity. But the Solar Energy Project won’t waste a thing. In fact, it will generate enough electricity to power 35% of all of the houses in South Australia.
It works by using over 10,000 tracking mirrors to push the sun’s rays onto a heat exchanger. Molten salt flows through this exchanger, absorbing the energy. It then flows into a thermal storage tank where it is kept until needed. When it’s time to be used, the salt is pumped into a steam generator where it gives enough heat to turn water to steam and generate electricity.
