5.2 CO2 Capture

Technology for capturing, storing and effectively utilizing CO2 emitted fromthermal power plants (CCUS) can be a key to achieving “zero CO2 emissions”from power plants.

Technology development/demonstration and geological study are nowpromoted to reduce costs and secure storage-sites.

Thermal power plantsCO2 Capture（ Carbon dioxide Capture ）

CO2 Utilization (CCU: Carbon dioxide Capture and Utilization)CO2 Storage (CCS: Carbon dioxide Capture and Storage)

Promotion of CCU and CCS

Technology for storing captured CO2 in the ground.

Although large amounts of CO2can possibly be stored, operating capability and storage capacity are the issues.

The research and development as well as verification test are in the process toward the realization of CCS technology around 2020.

Technology for producing valuable materials such as alternative fuels or chemical materials from utilizing captured CO2.

Development of more efficient technologies and expansion of application areas for utilizing a large amount of CO2 are the issues.

Coal is important fuel for power generation. But Environmental Protection is also important.

Contribution of Clean Coal Technology is still more important.

Environmental protection---SOx, NOx, Dust, Mercury, Toxics///

Global Warming-----------High efficiency, CCS, Biomass
