Title: DOE Industry Geothermal Program Briefing


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
