Ultra-Super Critical condition steam turbine Power Plants

Sectors:
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
