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

Green Car Congress

Sandia National Laboratories researchers recently delivered electricity produced by a new power-generating system to the Sandia-Kirtland Air Force Base electrical grid. 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.

New partnership to advance high-temperature PEM fuel cells; focus on heavy-duty applications

Green Car Congress

Traditional PEM fuel cells have a relatively low operating temperature, which makes for a low tolerance to hydrogen fuel impurities and makes waste-heat rejection a challenge for vehicles. A new partnership comprising Los Alamos National Laboratory, Advent Technology Holdings Inc.,
