Industrial heat pumps (IHPs) are a key decarbonization technology. As the domestic market for IHPs develops through increasing supply and demand, one area requiring additional focus is refrigerants and the need for consistent refrigerant policy. To plan IHP products and confidently enter the market at scale, IHP manufacturers require stable, consistent refrigerant policies. EPA overregulation of refrigerants without substantial research could have unintended environmental and operational impacts. This topic brief summarizes input from refrigerant and IHP manufacturers and details the diverse refrigerant landscape, the efficacies of available refrigerant choices, and the need for refrigerant certainty.
