APP Brown Coal Best Practice Workshop

1. APP Brown Coal Best Practice Workshop 23 – 27 June 2008 Melbourne and Latrobe Valley Victoria, Australia

2. Some Impressions • High skill of the people • Open with information • Unique resource of brown coal • Major business uncertainty with emissions trading • Looking for best practice on economic CO2 abatement

3. Plant Efficiency Plant efficiency not high important in Australia Not a business driver with coal at $5/T Efficiency issues relate to pressure (air and steam leakage) Pressure engineers needed Of high interest to Japan Japan very thorough approach

4. Materials Handling Coal mining and ash disposal Unique ash handling at Hazelwood Flocculation and separation very effective Of interest to Indian delegation Indian coals over 15% ash Low capital cost of bulldozers at Yallourn

5. Plant Availability Australian plant well maintained Skill level very high Power station is a system, all components important Performance and risk management Is Australian business driver Availability has greatly improved

6. Emissions Abatement Is becoming business driver in Australia Coal = $5/T but emissions of CO2 = $30/T Post-combustion capture favoured Site difficulty and cost

7. Interesting Bits Biomax algae plant at Hazelwood Ash handling system at Hazelwood Bulldozer mining at Yallourn River diversions at Yallourn and Hazelwood High availability and good economics at Loy Yang Coal drying by compression at Loy Yang

8. Conclusions Sharing best practice is very valuable Depends on the effort put in by participants Good for relations with government and stakeholders The APP mechanism should be promoted
