Korean Electricity Demand and CO2 Emission

CO2 Capture within KEPCO

Summary

Summary

For energy security and climate change, KEPCO offers

the comprehensible portfolio of CO2 capture technology

as well as other low carbon technologies

Post-combustion demo project currently scaled 0.1- 0.5

MW and two 10 MW pilot plants (dry sorbent and adv.

amine) are under development with a goal of bringing at

least one commercial demo project online by 2015

The 100 MW oxyfuel combustion project is now at the

FEED stage and will complete construction by 2015

KEPCO RI also develops the key technologies of pre-

combustion and CLC for advanced power generation

KEPCO with MKE support is moving big steps

forwarding to commercialize CCS technology by 2020
