SSAB produces first fossil-free steel and delivers it to Volvo Group; HYBRIT technology

Green Car Congress

The hydrogen gas used in the direct reduction process is produced by electrolysis of water with fossil-free electricity, and can be used directly or stored for later use. In May, HYBRIT began construction of a hydrogen unit on a pilot scale in connection with the pilot plant for direct reduction in LuleƄ.

Sandia team puts power into local grid with supercritical CO2 closed-loop Brayton-cycle turbine

Green Car Congress

Because so much energy is lost turning steam back into water in the Rankine cycle, at most a third of the power in the steam can be converted into electricity. It took us a long time to get the data needed to let us connect to the grid. In comparison, the Brayton cycle has a theoretical conversion efficiency upwards of 50%.
