Letter of Intent Due Date: March 27, 2026
Proposal Due Date: April 30, 2026
The field test activities to be funded through this Notice of Funding Opportunity (NOFO) seek to advance DOE’s goals and commitment to pushing the frontiers of science and engineering, advancing energy addition, and unleashing American energy innovation.
This NOFO may remain open for up to 72 months, with review cycles possibly occurring approximately every year, while funding lasts. The details of this NOFO (including descriptions of closed Topic Areas) are subject to change in future review cycles.
This NOFO targets field-scale tests at depths and temperatures appropriate for full-scale project development. These tests are intended to support research and development (R&D), testing, and evaluation of next-generation development technologies and approaches, and the applicability of those approaches in select real-world conditions. Additionally, this NOFO targets exploration drilling activities required to gather data to support the characterization and potential confirmation of promising next generation and hydrothermal prospects for electrical power production. These projects will directly support the DOE’s emphasis on learning-by-doing and helping to identify and focus R&D priorities. In the end, the knowledge gained from these tests will support future private sector funding decisions regarding the development approach and the location for development.
