   Propane may be the most suitable for high temperature heat pumps. [73] Ammonia (R717) and carbon dioxide also have a low GWP. As of 2023 smaller CO 2 heat pumps are not widely available and research and development of them continues. [74] A 2024 report said that refrigerants with GWP are vulnerable to further international restrictions. [75]
