The U.S. Department of Energy’s Geothermal Geophone Prize is a multi-phase competition designed to drive innovation in high-temperature seismic monitoring systems for Enhanced Geothermal Systems (EGS). The prize, part of the American-Made Challenges program, seeks to develop robust seismic sensors capable of operating in extreme geothermal environments, providing critical data for understanding subsurface conditions. The competition offers $2.55 million in cash and $1.1 million in vouchers across three phases. Phase 3, set to open in March 2024, focuses on building and testing prototypes, with two winning teams eligible to receive $350,000 and the opportunity to work with Lawrence Berkeley National Laboratory (LBNL) for field deployment.
Eligibility for Phase 3 is limited to those who successfully completed Phase 2, where participants advanced their designs for high-temperature seismic sensors. In Phase 3, competitors will fabricate prototypes and submit them for independent testing by Sandia National Laboratories (SNL). These tests will assess the sensors' ability to function under extreme geothermal conditions, such as high temperatures and pressures. The competition also emphasizes the importance of diversity, equity, and inclusion, requiring participants to integrate these principles into their project plans.
The final submission process includes delivering the physical prototype, submitting technical documentation, and participating in an evaluation call with SNL experts. Competitors will be judged on their prototype’s innovation, testing results, and commercialization potential. The competition aims to foster collaboration across sectors and encourage technological advancements that can significantly impact geothermal energy development, helping to achieve long-term deployment goals in the U.S. energy landscape. Winners will be announced in October 2025.
