  1. 1. UCG COMMERCIALISATION <ul><ul><li>CONCLUSION </li></ul></ul><ul><ul><ul><li>UCG gas production process is ready for commercialisation </li></ul></ul></ul><ul><ul><li>EVIDENCE </li></ul></ul><ul><ul><ul><li>Very long history of coal gas production and use </li></ul></ul></ul><ul><ul><ul><li>Long history of UCG gas production and use </li></ul></ul></ul><ul><ul><ul><li>Proven technology for UCG gas production and use </li></ul></ul></ul><ul><ul><ul><li>Perceived barriers to development overcome </li></ul></ul></ul><ul><ul><ul><li>Current commercial potential is high </li></ul></ul></ul>
  2. 2. COAL GAS HISTORY <ul><ul><li>1802 - First street lights in UK using coal gas </li></ul></ul><ul><ul><li>1812 - First gas works in UK </li></ul></ul><ul><ul><li>1820s- First coal gas light in Sydney </li></ul></ul><ul><ul><li>1862 - Hong Kong & China Gas Co. formed </li></ul></ul><ul><ul><li>1870s- Gas cooking introduced to Australia </li></ul></ul><ul><ul><li>1965-1975 Natural gas replaces coal gas in Australia </li></ul></ul><ul><ul><li>2002 - Hong Kong and China Gas Co produces and distributes 9 million cu.m. gas per day through 2800 km of pipe </li></ul></ul><ul><ul><li>2002 - IGCC plants operating in many countries </li></ul></ul>
  3. 3. UCG GAS HISTORY <ul><ul><li>FSU - Over 15 m t coal gasified since 1950s. Est. cost US$10 billion </li></ul></ul><ul><ul><li>USA - 50,000 t coal gasified since 1970s. Est. cost US$300m </li></ul></ul><ul><ul><li>Europe - Less than 10,000 t coal gasified </li></ul></ul><ul><ul><ul><ul><ul><li>since 1950s. Est. cost US$100m </li></ul></ul></ul></ul></ul><ul><ul><li>Australia - Over 32,000 t coal gasified 2000 – 2002. Est. cost US$5m </li></ul></ul>
  4. 4. TECHNOLOGY FOR COMMERCIAL USE <ul><li>Gas Production - more than 70 years of gas production and pilot test work </li></ul><ul><li>Gas Clean-up – filter systems developed for IGCC plants in US and Europe </li></ul><ul><li>Power Generation - low BTU combustors developed for turbines in IGCC plants </li></ul>
  5. 5. CURRENT COMMERCIAL POTENTIAL <ul><li>Chinchilla pilot burn has established </li></ul><ul><ul><li>Continuous gas production for 30 months </li></ul></ul><ul><ul><li>Demonstration of decommissioning </li></ul></ul><ul><ul><li>Proven environmental acceptance </li></ul></ul><ul><ul><li>Feasibility studies for power generation from 40 to 400MW, using proven plant </li></ul></ul><ul><ul><li>Highly competitive economics (<US1.5c/kWh) </li></ul></ul>
  6. 6. UCG PILOT PLANT BURN CHINCHILLA, QLD
  7. 7. CHINCHILLA GAS PRODUCTION Dec 1999 – April 2002 After Blinderman et al. (2002)
  8. 8. UCG COMMERCIAL BENEFITS <ul><li>Wellhead gas costs less than 50% of natural gas on an energy equivalent basis </li></ul><ul><li>Base load p ower costs using UCG gas comparable with much large r supercritical coal-fired stations </li></ul><ul><li>Additional revenue from sale of by-products </li></ul><ul><li>CO2 emissions for CCGT power plant 2 5 % less than best coal-fired stations </li></ul><ul><li>Added emission benefits with CO2 sequestration </li></ul><ul><li>Wide range of alternative uses for UCG syngas </li></ul>
  9. 9. COMMERCIAL ISSUES BEING OVERCOME <ul><li>No access to FSU experience to the West </li></ul><ul><li>Resolved using Exergy UCG technology </li></ul><ul><li>Concerns for environmental issues </li></ul><ul><ul><li> Satisfied by monitoring evidence </li></ul></ul><ul><li>Perceived high cost of production </li></ul><ul><li>Resolved by Chinchilla costed plant design </li></ul><ul><li>Focus on Govt.-funded R&D </li></ul><ul><li>Industry support being developed </li></ul><ul><li>Financing for “first-of-a-kind” project </li></ul><ul><ul><ul><li>Issues identified – task incomplete </li></ul></ul></ul>
