Student Competition Where would YOU place the next geothermal production well at the FORGE site in Utah? GTO is challenging students to use spatial and statistical data analysis and visualization. • • Administered by Idaho National Lab, this competition is open to university and high school students nationwide. 1 st, 2 nd, and 3 rd place winners will receive a cash prize. Student teams can win up to $5, 000. Challenge: • • • Analyze publicly available FORGE data. Develop a thesis and propose a site. Create no more than 10 data visualizations. Submit final portfolio, along with a one-page explanation, by April 10. To learn more, visit utahforge. com/studentcomp Register now! Final portfolios are due April 10. U. S.

Frontier Observatory for Research in Geothermal Energy: A Roadmap Alexis Mc. Kittrick, Ph. D. Research Staff Member, IDA/STPI February 19, 2019 Geothermal Technologies Office / Q 1 2019 Webinar

IDA Science and Technology Policy Institute (STPI) • Federally funded research and development center • Operated by a not-for-profit corporation, the Institute for Defense Analyses (IDA) • Congressionally chartered to support the White House Office of Science and Technology Policy (OSTP) and other Executive Branch S&T agencies • Provides rigorous and objective advice and analysis, including: – Policy assessments – Strategic planning – Technology evaluation 8

FORGE Roadmap Objectives • GTO requested STPI develop a roadmap to provide recommendations for the critical research that will occur during the 5 -year implementation phase of FORGE • The research recommendations are intended to make progress towards a rigorous and reproducible EGS methodology • The roadmap combines feedback from the EGS research community with DOE’s EGS priorities to represent the most critical areas of research for FORGE 9

Value of Community Input • EGS community input was used to inform the technical foundation of the roadmap, alongside other inputs: – Literature review – DOE and EGS research community interviews – FORGE Roadmap Development Workshop • FORGE Roadmap offers guidance from EGS community to managers and operators of the site: – Utah FORGE Team – Science and Technology Analysis Team (STAT) – DOE GTO 10

Overview of STPI’s Roadmap Development Process 11

FORGE Roadmap Scope • The FORGE Roadmap describes: – Critical research areas that, if successfully executed, can overcome key technical challenges facing EGS, including: • Core research actions that have no known technical solution or must be addressed to develop a rigorous and reproducible EGS methodology • Supporting research actions that would improve existing technical solutions to enable a robust methodology across EGS reservoirs with a variety of characteristics – Enabling R&D that has the potential to enhance knowledge, capabilities, and operational expertise in EGS development, but does not fall into a critical research area – Implementation principles that can enhance the usefulness of data collected at FORGE • The following topics are considered out of scope: – Individual research projects – Economic, social, and regulatory barriers to EGS commercialization – Public engagement 12
