【 摘 要 】

Characterizing productive geothermal systems is challenging yet critical to identify and develop an estimated 30 gigawatts electric (GWe) of undiscovered hydrothermal resources in the western U.S. This paper, undertaken by the U.S. Department of Energy???s Geothermal Technologies Office (GTO), summarizes needs and technical pathways that target the key geothermal signatures of temperature, permeability, and fluid content, and develops the time evolution of these pathways, tying in past and current GTO exploration Research and Development (R&D) projects. Beginning on a five-year timescale and projecting out to 2030, the paper assesses technologies that could accelerate the confirmation of 30 GWe. The resulting structure forms the basis for a Geothermal Exploration Technologies Roadmap, a strategic development plan to help guide GTO R&D investments that will lower the risk and cost of geothermal prospect identification. This roadmap is currently open for public comment. Send your comments to [e-mail].
