Smelting Steel Without Fossil Fuels: Solar Power Shatters the 1,000°C Barrier for Industrial Heating

Credit: ETH Zurich/ Emiliano CasatiSwiss researchers have actually developed a solar energy technique utilizing synthetic quartz to attain temperature levels above 1,000 ° C for industrial processes, possibly replacing fossil fuels in the production of products like steel and cement.Instead of burning fossil fuels to reach the temperatures required to smelt steel and cook cement, scientists in Switzerland want to use heat from the sun. The proof-of-concept research study uses artificial quartz to trap solar energy at temperatures over 1,000 ° C( 1,832 ° F), demonstrating the methods potential function in providing clean energy for carbon-intensive markets. Manufacturing these materials needs temperature levels over 1,000 ° C and relies heavily on burning fossil fuels for heat. When they exposed the gadget to an energy flux equivalent to the light coming from 136 suns, the absorber plate reached 1,050 ° C( 1,922 ° F), whereas the other end of the quartz rod remained at 600 ° C( 1,112 ° F). Breaking New Ground in Solar Thermal Trapping” Previous research study has actually just managed to demonstrate the thermal-trap impact up to 170 ° C( 338 ° F), “says Casati.
