Solar thermal trap targets 1,000°C for decarbonizing industries

A Swiss research team at ETH Zurich is developing a solar thermal system to achieve temperatures above 1,000°C for industrial processes. The system uses a thermal-trap effect to efficiently transfer heat. This innovation could help decarbonize industries like cement and metallurgy. The US Department of Energy is also investing in concentrating solar technologies to accelerate commercial deployment and support green hydrogen production.
