Title: GeoVision Analysis Supporting Task Force Report: Geothermal Hybrid Systems

Abstract

This report documents findings from the Hybrid Systems Task Force of the U.S. Department of Energy's (DOE) Geothermal Technologies Office (GTO) Geothermal Vision Study (GeoVision Study). The GeoVision Study projects and quantifies the future electric and nonelectric deployment potentials of geothermal technologies within a range of scenarios in addition to their impacts on U.S. jobs, the economy, and environment. The Hybrid Systems Task Force is one of seven task forces within the GeoVision Study with the others being Exploration and Confirmation, Potential to Penetration, Thermal Applications, Reservoir Maintenance and Development, Institutional Market Barriers, and Social and Environmental Impacts. A summary of the study is captured in DOE’s report, GeoVision: Harnessing the Heat Beneath Our Feet. The Hybrid Systems Task Force investigated geothermal hybrid systems that have potential to increase the utilization of geothermal resources and/or decrease the costs of geothermal power generation. Applications evaluated include: hybrid thermal power generation in which geothermal energy is coupled with solar or fossil heat sources; use of geothermal energy to provide process heat for thermal desalination or CO2 capture from fossil power plants; analysis of compressed air energy storage augmented with geothermal energy; as well as an assessment of potential mineral recovery from geothermalmore » brines. This report additionally discusses areas of research and development that should be pursued to enhance the ability of geothermal hybrid systems to provide valuable benefits in operational flexibility, reduction of project risks, increased energy security, and the ability to recover critical and strategic materials.« less
