BraytonTour Pasch 2014

Supercritical carbon dioxide closed Brayton cycle. Sandia National Labs is researching and developing a new thermal-to-electic power generation cycle that is far more efficient than traditional steam power cycles. The working fluid is carbon dioxide instead of water which has been used in steam cycles for over a century. The power cycle is closed, which means that carbon dioxide is not generated nor released to the atmosphere by the power cycle. This technology can use any source of heat to operate.
