Existing CCS technologies in world

Energy Penalty: 7~15% Cost: 20~60 $ / t CO2

If China adopts these approaches

Additional energy input - 700 millions of tce/y in China of 2050

Energy security will be more serious!

Also, Hundred billions US$ per year 

Challenge: Is it sustainable?

Key points

� Based on special issues of China, high carbon energy Vs.low carbon tech, global insight from energy resource and

economic for S.T. Develop.;

� Need to develop innovative CCS in long term, instead of existing CCS tech, unacceptable for developing

countries;

� Focus on low energy penalty, instead of zero emission;

� Targets of CCS: low energy penalty with less than 5

points, low cost with less than 10 $/ ton CO2;

� Successful demons. of CCS in developed countries.
