Full conversion to natural refrigerants - Feasible and likely to happen?

Number: 1295

Author(s) : NEKSÅ P.

Summary

The paper reflects on answers to the question whether a full conversion to natural refrigerants is feasible from a holistic view based on technological, cost- and environmental perspectives. The reflections are partly based on developments in certain applications in a historical context, as well as in light of new frameworks, like the new EU F-gas directive and the outcome of COP28. The fact that refrigerants controlled by the Montreal Protocol and its Kigali-amendment is still very widespread in use for various applications makes it urgent to transition these to low-GWP refrigerants. The only longer-term solution based on fluorinated refrigerants is the unsaturated HFCs, commonly denoted as HFOs. These fluids are known to be PFAS substances contributing to TFA pollution when decomposed in the atmosphere. Based on the analysis, it may be envisioned that a full conversion to natural refrigerants is feasible and may also be the most adequate option.
