Solar energy used for high-temperature industrial processes

Researchers at ETH Zurich have developed a thermal trap using solar radiation to deliver high temperatures needed for industrial processes, reaching 1050 degrees Celsius in lab experiments. This innovation could help decarbonize energy-intensive industries currently reliant on fossil fuels. The technology minimizes radiative heat losses, potentially improving the efficiency of solar absorption for large-scale solar plants. Further technical and economic analyses are needed for implementation.
