    Supercritical Coal Plant Energy Education

    Supercritical coal plants are a type of coalfired power plant used in more modern designs. They differ from traditional coal power plants because the water running through it works as a supercritical fluid, meaning it is neither a liquid or a occurs when water reaches its critical point under high pressures and temperatures, specifically at 22 MPa and 374 o C.
