10. Natural Gas in China
• The share of natural gas in the energy mix will increase from 4%
in 2010 to 10% in 2020
• The government is reforming the gas market, current regulated
“city-gate gas prices” are around 3 to 3.3 per cm in the east of
China
• Natural gas will be applied for generating electricity in major
cities with tight “environment capacity”, such as Beijing,
Shenzhen, Shanghai, Guangzhou
• The CCGT capacity is estimated to increase from 20GW in 2010
to 60GW in 2015 and 110GW in 2020
• Some pioneer projects are studying CCS in gas-fired power plants
in China

12. Project Objectives
• Develop a CCS roadmap for natural gas-based CHP
plants;
• Carry out a techno-economic feasibility analysis for a CCS
pilot scale demonstration on the Gaojing CHP plant;
• Formulate a CCS-readiness plan for natural gas-based
CHP plants;
• Establish a capacity strengthening programme for
various stakeholder groups concerned with the
application of CCS for gas fired CHP systems.

15. Datang Gas CCS Plan
• A CCS pilot scale demonstration for Gaojing natural gas
power plant through post-combustion chemical
scrubbing (3 tonne per day)
• Establish CCS-readiness guidelines to meet new and
future CCS retrofitting requirements for applications to
all natural gas power plants within PRC
• ADB TA provides an important assessment of strategic
and technical options and impact on economic
competitiveness (draft report by July 2013; followed by
stakeholder workshops in Sep and Oct)

25. Final Remark
• Gas fired power plants will increase rapidly though it is
still a small proportion of total generation capacity
• CCGT power plants are likely first deployed in large cities
and developed regions, with limit land resource and high
population density, therefore CCS Ready is very
important to avoid the carbon lock-in effect
• Datang and Huaneng are developing pilot CO2 capture
projects in gas-fired power plants
• SNG and gas processing will provide low-cost
opportunities for CCS in the gas industry
