The demand of coal will increase in the world, especially in Asia by 2030. On the other hand, coal is a major source of CO2 emission. Development of clean coal technologies is necessary to meet the increasing demand and avoid rapid global warming. The major subject of coal utilization is reduction of CO2 emission from coal firing power plant and this paper reviews recent activities and developments of CO2 reduction technologies from coal firing power plant which are increase of the plant thermal efficiency by 700 degree advanced ultra supercritical boiler, use of biomass with coal and carbon capture and storage technologies. As increase of the demand, low rank coal (LRC) such as lignite and sub-bituminous coal, which has not been used as much as bituminous coal, is paid attention for future resources. Gasification technologies are suitable for LRC and a new type of gasifier is introduced.
