GHG Emission in Korea
CCS-related Policy in Korea
Korea in 2020 accounts for only 1.6%, 2.1% and 2% of the respective
electric capacity, electricity generation, and CO2 emission in global scale.
Commitment of the 30% GHG reduction below BAU by 2020 (Nov.’09)
Framework Act on Low Carbon, Green Growth (14 April 2010)
Presidential Committee on Green Growth: Major Policies and Plans including
CCS
Announcement of CCS Master Plan (July 13 2010) including two large scale
demonstration by 2020
CO2 will be regulated based on the Clean Air Conservation Act (amended
13 Jan. 2010)
Established Korea CCS Association (KCCA) in MKE, leading by KEPCO
(Nov. 2010)
Carbon emission trading system slated to start on Jan. 2015 rather than
from Jan. 2013 (Bill revised Feb. 2011)

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
