Huaneng Group took the lead in China to put forth the Plan of “Green Coal-fired Power”, which aims to
high-efficiency coal-fired power generation and nearly zero emission of pollutants. Then, on May 17, 2005,
it signed a contract for the feasibility study of coal-gasification technical transformation project phase 1 of
the plan with Northwest Electric Power Design Institute, marking the formal launch of the plan. The overall
goal of “Green Coal-fired Power” is: to research, develop, demonstrate and promote a coal-based energy
system that generates power from gasified hydrogen and hydrogen energy with CO2 separated and treated,
to significantly enhance the efficiency of coal-based power generation, to enable the coal-based power generation system to reach nearly zero emission of pollutants, including CO2.
