Abstract: Geothermal heat pumps (GHPs), also referred to as ground-source heat pumps or Geo-exchange, have been proven capable of producing large reductions in energy use and associated carbon emissions for space conditioning and water heating in buildings. However, the current adoption rate of GHPs in the United States is still low, and GHPs receive little attention from either the public or policy makers. This report gives an overview of the status of GHP technology and its application in the United States, cost and performance of the state-of-the art GHP systems, barriers preventing wider adoption, and technologies under development that have potential to help overcome these barriers. This report also presents an assessment of the technical potential of applying GHP systems in businesses and homes in the United States. The assessed technical potential includes energy savings, carbon emissions reductions, and consumer energy cost savings. This assessment is based on energy consumption data obtained from the latest residential and commercial buildings energy consumption surveys conducted by the US Department of Energy’s Energy Information Administration (EIA). It uses the energy savings data of GHP systems compared with existing conventional heating, ventilation, and air-conditioning (HVAC) systems, which were obtained from numerous published case studies and validated computer simulations. The impacts of various climate and geological conditions, as well as the efficiency and market share of existing conventional . . .
