Pirates.BZ Tech Startup NewsFourth Power, founded by MIT Professor Asegun Henry, has developed thermal batteries that store energy as extreme heat using molten metal and carbon bricks. The system operates at temperatures reaching nearly half as hot as the sun, between 1,900 and 2,400°C, and can provide 10 to 100 hours of electricity storage at a fraction of lithium-ion costs. Aimed at power grids and data centres, the company plans to launch a demonstration unit later this year. https://news.mit.edu/2026/turning-extreme-heat-large-scale-energy-storage-0318 #Tech #Startup #News #ClimateTech #FourthPower
Turning extreme heat into large-scale energy storage
Fourth Power, founded by MIT Professor Asegun Henry, is developing large-scale thermal batteries that store excess electricity from utility grids and power producers by heating graphite blocks to extreme temperatures.
