          The supercritical CO 2 cycle can operate at lower temperature than the Brayton cycle (550°C vs 850°C), but higher pressure (20 MPa vs 8 MPa), while achieving comparable efficiency of 45%. Higher temperatures could raise the efficiency above 50%. The turbomachinery is high speed and very compact.

          Supercritical steam generator is a type of boiler that operates at supercritical pressure, frequently used in the production of electric power. In contrast to a subcritical boiler in which bubbles can form, a supercritical steam generator operates at pressures above the critical pressure – 3,200 psi or 22 MPa.
