United States Geothermal Direct-Use Database - 2025 Update

Published by National Renewable Energy Laboratory | Department of Energy | Catalog Last Checked: April 25, 2026 at 08:43 AM | Dataset Last Updated: December 02, 2025 at 11:40 PM
This database of geothermal direct-use systems in the U.S. was updated as part of the Geothermal Market Report from the National Renewable Energy Laboratory (NREL). Types of direct-use applications include hot springs resorts and pools, aquaculture farms, greenhouses, and district heating systems, among others; power-generating facilities and ground-source heat pumps were excluded. Where possible, the current operation status, open and close dates, well data, and other technical data were included for each entry. The database is housed in an Excel file that organizes site attributes, application types, technical parameters, costs, location data, and project status information into labeled columns with consistent units and source references.
