China’s coal fired electric power sector challenges and opportunities
Dr Andrew MinchenerPrincipal Associate, IEA Clean Coal Centre
Scope of presentation (part of IEACCC study in progress)
• Status of the generation companies• Overview of coal-fired power within the
generation mix• Efficiency, environmental and economic
considerations• Chinese manufacturing capabilities• CO2 mitigation possibilities• Creating future near zero emissions power
generation power plants
Status of the generation companies
• Five largest companies own ~40% of generation capacity (down from~46% when State Power Corporation was broken up)
• All five now buying up mining groups to ensure some stability in coal supply and price
• Several involved in coal to chemicals projects • All introducing advanced CCTs while closing old, small
units (in line with Government policy)
Issues arising
• Massive year-on-year growth in coal fired capacity
• Older, smaller units are inefficient and polluting
• Largest market in the world for the larger, environmentally acceptable units with advanced steam conditions

Environmental issues of increasing concern
Coal related CO2 mitigation in China?
• Improve efficiency of coal fired power generation plus limit emissions of conventional pollutants (near term)
• Introduce cofiring of coal with CO2 neutral feedstocks (near to medium term)
• Develop and deploy CO2 capture and storage techniques (longer term)

Environmental regulations in China
• New SO2 , NOx , and PM standards (2004) within World Bank guidelines
SO2 standards equivalent to OECD average• Goal: FGD at 60% capacity by 2010, supported by incentive in
electricity price for FGD use together with tax on SO2 emissions• Government focus on developing cost-effective FGD systems
NOx standards relatively modest compared to OECD • Can be satisfied by Chinese low-NOx burners but power
companies have begun importing SCNR and SCR systems
PM emission standards require higher efficiency ESPs
China FGD installations
• Government 2010 target for FGD exceeded in 2008
• By end of 2008, 379 GWe out of 574 GWe coal fired power plants had FGD installed
• From 2007 onwards, national SO2 emissions began to decrease

CO2 mitigation by cofiring
• Technically applicable in China as in EU
• Potential is very significant
• Policy barriers must be overcome
• Considerable scope for EU-China cooperation to resolve the perceived problems
CO2 capture and storage
China CCS R&D activities
National Basic Research (973) Programme• Utilising GHG as resources in EOR and Geological
Storage• Syngas production based on coal gasification &
pyrolysis• High efficiency conversion of natural gas & syngas• High efficiency heat-work transfer study of gas
turbinesNational High-Tech (863) Programme• Development of Carbon Capture and Storage

Near Zero Emissions from Coal (NZEC)
Includes a collaborative project, supported by DECC and MOST, to:– build capacity in China to determine the best options
for carbon dioxide capture, transport and geological storage; and
– examine the potential for the development and demonstration of CCS technology in China and its deployment in the future.

Scope of Phase 1 programme
• WP1 – Knowledge Sharing & Capacity Building
• WP2 – Future Energy Technology Perspectives
• WP3 – Case Studies for Carbon Capture
• WP4 – Carbon Storage Potential
• WP5 – Policy Assessment & Roadmap
CO2 storage capacity assessments
(EU-China partnership on climate change)
Shenhua CTL plant (CCS project being developed)
The way forward?
• Need to pursue a low carbon development path with Chinese characteristics, with clearly defined targets and priority actions– Reduction in energy use per unit of GDP, with consequent
reduction in CO2 emissions
• Recognition that China can fulfil a leadership role in clean coal technology with carbon capture and storage– China already a growing provider of equipment and know-
how in power generation, both domestically and overseas – Tremendous scope to build on the base to integrate CCS
techniques as necessary– Build on joint ventures and licensing arrangements already in
place
