Topic Brief - Consistent Refrigerant Policy Is Essential for Investment in Industrial Heat Pump Market

• Industrial end users interested in IHPs will need to understand the role of refrigerants and the relevant state or regional regulations to decide on IHP system design for their applications, further underscoring the need for consistent refrigerant policies. [...] Therefore, the large-scale transformation of the IHP market requires a comprehensive review of refrigerant availability and suitability by federal and state authorities and clear and consistent policies regarding the future of refrigerants. [...] Despite this, some jurisdictions, especially in the buildings sector, restrict the use of ammonia as a refrigerant because of its toxicity and light flammability, and some potential end users are uncomfortable with its use due to lack of experience. [...] Our team is engaging with companies from across the diverse supply chain, as well as federal, state, and utility-level agencies and offices, to ensure that the connective infrastructure and knowledge base is adequate to support the transition. [...] Additional research is needed to and state and federal government determine best practices and policies that can be agencies including EPA and DOE gleaned from the EU experience, global perspective Refrigerant choice and efficacy should be an early IHP Alliance, utilities, end users, other 2025– focus in IHP pilots and demonstrations that are supporting entities and institutions urgently needed in.
