22. Summary
q For energy security and climate change, KEPCO offers the
comprehensible portfolio of CO2 capture technology.
q Two 10 MW pilot plants (dry sorbent and adv. amine) scaled-up
based on the results from 0.1- 0.5 MW test-bed runs are under
shakedown test, aiming to bring at least one commercial demo
project online by 2015~2017.
q The FEED study of the 100 MW oxyfuel combustion project was
completed in 2012 and MOTIE was putting the 100 MW prject on
hold recently.
q KEPCO RI with others also develops the key technologies of
pre-combustion and CLC with solid sorbents for advanced
power generation.
q KEPCOs with MOTIE’s support is moving big steps forwarding
to commercialize CCS technology by 2020.
q Looking for funding, strategic partners and opportunities to
demonstrate our technologies in Korea
