To address this knowledge gap, we developed and used the generalizable GEOthermal technoeconomic simulator (genGEO). GETEM and GEOPHIRES are the two primary tools that previously existed for techno-economic geothermal power assessments. While reputable and widely used, these tools rely on unpublished ASPEN results and are thus not generalizable or transparent enough to be applied to power plants besides those that use ORC power cycles and water as the heat extraction fluid. In contrast, genGEO transparently uses publicly available data to estimate the generation and cost of geothermal power plants without propriety software, and its generalizability allows it to be applied to sedimentary basin geothermal power plants that use CO 2 to extract heat.
