Policies to Capture the Potential of Next-Generation Geothermal 24

1. Continue funding research, development, and demonstration of next-generation geothermal and novel drilling technologies 24

2. Continue incentivizing the development of firm, dispatchable clean energy sources with clean energy tax credits 25

3. De-risk early phases of geothermal development through federal loans, loan guarantees, and lending support mechanisms 25

4. Improve project certainty through streamlined permitting 26

5. Leverage and optimize existing federal financing tools to expand American geothermal companies' access to domestic and international energy markets 26
