Glossary: Supercritical Ultrasupercritical technologySupercritical (SC) and ultrasupercritical (USC) power plants operate at temperatures and pressures above the critical point of water, above the temperature and pressure at which the liquid and gas phases of water coexist in equilibrium, at which point there is .
Supercritical fluids Supercritical fluidsWhen a compound is subjected to a pressure and a temperature higher than its critical point, the fluid is said to be " supercritical" . In the supercritical region, the fluid exhibits particular proporties and has an intermediate behavior between that of a liquid and a gas.
