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. 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%.

Northvolt to build third gigafactory in Germany

Green Car Congress

The region hosts the cleanest energy grid in Germany, one which is characterized by a surplus of electricity generated by onshore and offshore wind power and reinforced by clean energy provided through grid interconnections to Denmark and Norway. The selection of Heide, Schleswig-Holstein, is key to fulfilment of this objective.
