CRADA NFE-23-09890 Final Report Scoping Study of Integrated Geothermal CO2 Heat Pump and Water Well System in Cold Climate Regions

Summary

This scoping study addresses the challenge of maintaining efficient heat pump performance in cold climates, where conventional systems struggle with decreased capacity and high energy consumption. It proposes and evaluates an innovative approach integrating a CO2 heat pump with existing water well systems to leverage stable ground temperatures. The analysis indicates the integrated CO2 geothermal system offers superior performance with an average COP of 3.8 and potential for significant energy savings and reduced electricity demand in cold regions, compared to R-410A air-source heat pumps.
