Ultra-Super Critical condition steam turbine Power Plants

Objective
Country
Japan

USC steam turbine power plants are highly efficient generation system which uses Ultra-Super Critical condition (USC) steam (e.g. steam pressure at 24.1MPa or more and steam temperature at 593°C or more).

Organisation providing the technology
Mitsubishi Hitachi Power Systems, Ltd. (MHPS)
Benefits
  • Energy saving: approx. 3,500 TJ/yr (LHV)
  • CO2 reduction: approx. 330 ktCO2/yr

(500MW power plant, 80% of capacity factor)
(compared to Supercritical condition steam turbine)

Co-benefits
  • Emissions of air pollutants per power generation (kWh) are lower (e.g. SOx, dust) (if compared to conventional coal-fired power plant)
  • Reduction of thermal effluent
Differentiators
  1. High efficiency (approx. 45%(LHV)) by higher steam temperature and pressure
  2. Variable pressure operation and operational flexibility
  3. Large capacity and higher reliability
  4. Environmentally clean power generation
Succes factors and requirements

Environmental regulation (e.g. air pollutants)

Countries where implemented
Netherlands
