• Description of tasks in WP3
• Task 1 Initial Phase Definition of basic
  conditions and reference basis
• Completed in August 2008.
• Typical Chinese site, Shenhua and Datong coals
• Task 2 Case Studies (similar scope to IEA GHG
  studies)
• Subtask 2.1 Oxyfuel
• OX1 Oxyfuel, new build Capture-Ready, (Doosan
  Babcock ZJU)
• b) OX2 Oxyfuel, capture retrofit to existing
  sub-critical plant combined with ASCBTR,
  (Doosan-Babcock)
• Now in progress.
• 800MW, superheater steam temperature 600ºC
• 350MW existing Chinese plants, will be upgraded
  to supercritical steam conditions and oxyfuel
  capture with essentially no loss in efficiency

Subtask 2.2 Post-combustion
Houshi Power Plant 600 MW supercritical Steam
pressure 266 bar Superheater steam temperature
540.6 ºC
a) PC1 Post-combustion capture, new build,
(Alstom DCE) b) PC2 Post-combustion capture,
capture-ready, and retrofit (Alstom DTE) c)
PC3 Super-critical with post-combustion capture
by chemical absorption and membrane contactor
(ZJU) d) PC4 Possible post-combustion capture
options for existing sub-critical and
supercritical power plants (i.e. Chinese power
plant fleet in 10-20 years time) (NCEPU)

• 600 MW supercritical sliding pressure PC boiler

Subtask 2.4 Case study suitable for specific
conditions of China Coal based polygeneration
systems integrating pre-combustion capture and
alternative fuel (MeOH or DME) production,
including liquid fuel transport from western
China via pipeline for use in power plants.
(IETZJU) Task 3 Transportation
technologies Wuhan and Shell collaborating on
pipeline models for China. Will be specifying
typical Chinese plant-to-storage pipeline routes
shortly to assess pipeline design and indicative
costs. Task 4 Comparison of case studies and
key technologies to be developed in the next
phase GreenGen pre-feasibility study in progress,
other sub-tasks to start in New Year

Conclusions Work Package progressing on time Good
exchange of information between Chinese and UK
partners Number of collaborative activities
planned before next meeting in early 2009 Interim
report at end of November 2008.
