Fourth Power’s Sci-Fi Thermal Batteries Challenge Costly Gas Plants

Fourth Power’s Sci-Fi Thermal Batteries Could Be Cheaper Than Pricey Natural Gas Power Plants Fourth Power’s sci-fi thermal batteries could be cheaper than pricey natural gas power plants, and that’s shaking up the future of clean energy. Instead of relying on lithium-ion or costly gas peaker plants, the startup is betting on superheated liquid tin and futuristic thermal storage to keep renewable power flowing around the clock.

By building large-scale, long-duration thermal batteries, Fourth Power hopes to make solar and wind a no-brainer choice for reliable 24/7 electricity. How Fourth Power’s Thermal Batteries Work At the heart of this breakthrough is a clever process. Electricity from the grid heats blocks of carbon inside insulated chambers filled with argon gas. When power is needed, molten tin heated to 2,400°C (4,352°F) flows through graphite pipes …
