Jun 21, 2016 · In ultra-supercritical steam (USC) power plants, the extreme boiler temperature and pressure heat the water so that it becomes a 'supercritical' fluid that exhibits properties of liquid and gas phases. In this state, supercritical steam is much more efficient at driving the giant turbines that spin the plant's generators.
