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

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

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

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

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

Hardware Development Downhole Pump Temperature limitations Materials Demonstration –Anti-scalant Coatings –Corrosion Protection Combination Logging Tools –PTS-Density Tool Advanced H 2 S abatement

Conversion Technology Aggressively Develop and Demonstrate a power cycle that is economic in the low temperature range. – o F –Lower temperatures?

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

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

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

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
