  1. DOE- Industry Geothermal Program Briefing Geothermal Resources Council Perspective March 20, 2003

  2. Data Gathering Procedure • Jay Nathwani and Joel Renner presentation to GRC Board, 1/30/2003 • Sabodh Garg Facilitator • Initial input from 16 GRC Board Members • Subsequent Discussion and Comments Available in Text Form

  3. Summary of Recommendations • Exploration and Resource Definition • Drilling Technology • Reservoir Confirmation, Characterization and Management • Enhanced Geothermal Systems • Hardware Development • Low Temperature Conversion Technology • Basic Research Efforts • Information Dissemination, Education and Outreach • Non-Electrical Uses and Distributed Power

  4. Exploration and Resource Definition • Expanded GRED (Geothermal Resource Exploration and Definition) • Cost-Shared Drilling • Slim-hole • Reservoir confirmation • New Exploration • Fracture Targeting • Geochemical Techniques • Geophysical Techniques

  5. Drilling Technology • Reactivate GDO (Geothermal Drilling Organization) • Continue Lost Circulation Control Research • Develop Suite of Cementing Materials and Techniques • Basic Research • Bit Technology • Logging while drilling

  6. Reservoir Confirmation, Characterization and Management • Integration of Basic Geophysical, Geochemical Data into more Robust Reservoir Models • Incorporate Fluid Chemistry and non-conservative tracers into numerical modeling techniques • Support publication of case studies with demonstrated efficacy of Reservoir Modeling

  7. Enhanced Geothermal Systems • Expand Funding Level • Potential for near-term deployment • Requirement to test multiple concepts • Near-term focus should be on EGS coupled with producing hydrothermal

  8. Hardware Development • Downhole Pump Temperature limitations • Materials Demonstration • Anti-scalant Coatings • Corrosion Protection • Combination Logging Tools • PTS-Density Tool • Advanced H2S abatement

  9. Conversion Technology • Aggressively Develop and Demonstrate a power cycle that is economic in the low temperature range. • 212-300 oF • Lower temperatures?

  10. Distributed Power and Non-Electric Uses • Off-grid Village Power Generation • 50 kW to 5 MW • Mineral Recovery • Zinc, Manganese • Silica • Lithium, Potassium, Cesium, Rubidium • Agribusiness and space heat, industrial process heat

  11. Information Dissemination, Education and Outreach • Maintain funding for Scientific Meetings and Publications • Geothermal is a viable renewable energy source for the future • Indigenous • Energy security • Low Emissions • Educate Public, Policy Makers

  12. US and Mexico Co-operative Work • Presented to and Discussed with Mexico Secretary of Energy Martens • Geothermal Reservoir Identification and Management • Geothermal Deployment Strategy • Integrated Uses of Geothermal Resources • Secretary Martens intends to discuss with US Secretary of Energy Abraham

  13. Barriers to Short Term Deployment • Lack of Power Sales Contracts • Capital Front-End Loading of Geothermal Projects • Limited Inventory of Proven Resources • Attracting Capital Investment
