What is Geologic Thermal Energy Storage (GeoTES)?
GeoTES concept consists of three main components:
- Convert excess electricity to hot water and pump it into a deep sedimentary reservoir
- Store the thermal energy in the subsurface
- When needed, recover hot water for energy generation or direct use applications
Key Project Tasks
- Lessons learned from previous high temperature aquifer thermal energy storage (HT-ATES) projects
- Modeling case studies for potentially favorable formations for GeoTES (Green River Basin, Illinois Basin, Cranfield)
- Laboratory experiments to evaluate mineral-brine reactivity using core samples and formation water chemistry from the Weber/Tensleep Formation, WY
- Batch modeling to evaluate experiments
- Determine ability to mitigate potential geochemical issues and identify site selection criteria (Go/No Go)
- Thermal storage modeling and scenario evaluation to identify optimal conditions for thermal storage and recovery efficiency – using generic and site-specific cases
