Episode notes
Directional Drilling Enhances Output
- Directional rotary drilling and subsurface stimulation create geothermal reservoirs where none existed.
- Horizontal drilling connects multiple wells, greatly increasing geothermal energy extraction.
Enhanced Geothermal Breakthrough
- Enhanced geothermal creates hydrothermal reservoirs by fracturing deep, hotter rock.
- This technology expands geothermal access beyond shallow, natural steam sites.
Geothermal's Political and Power Edge
- Geothermal offers 24/7 baseload power with bipartisan political support.
- Domestic, clean, and resilient, it stands out among renewable technologies today.
