Supercritical carbon dioxide (sCO 2) power cycle is an innovative concept for converting thermal energy to electrical energy.It uses sCO 2 as the working fluid medium in a closed or semi-closed Brayton thermodynamic cycle. The sCO 2 power cycles have several benefits such as high cycle efficiency, small equipment size and plant footprint (and therefore lower capital cost) and the
