Measuring the Costs and Benefits of Nationwide Geothermal Heat Pump Deployment-A Progress Report

摘要

The use of geothermal heat pump systems (GHPs) in the United States is marginal, despite their high efficiency and minimal greenhouse gas emissions. To evaluate the consequences of broader deployment of GHPs we are conducting a national cost-benefit analysis for 30 metropolitan regions. The three-year effort is known as the GHPsRUS Project ("geothermal heat pumps are U.S."). In previous papers, we reported on the project's basic approach and progress in acquiring geological data needed to quantitatively model GHP design specifications and cost. In this paper, we report on the progress of the GHPsRUS Project.
