UK researchers have designed a pumped thermal energy storage system for large-scale grid electricity, stored as high-grade thermal energy. It is based on a Brayton PTES concept demonstrated by ...
ALBUQUERQUE, N.M. — For the first time, Sandia National Laboratories researchers delivered electricity produced by a new power-generating system to the Sandia-Kirtland Air Force Base electrical grid.
The illustration shows a recompression closed Brayton cycle with arrows indicating the flow of supercritical carbon-dioxide (S- CO2). Starting at the lower left corner, S-CO2 is heated and sent ...
