Aspects involved in the replacement of refrigerants by low GWP gases.

Author(s) : KUIJPERS L.

Summary

In the early 1990s, when the replacement of CFCs was the important issue, the discussion was dominated by how fluorocarbons, whether HCFCs or HFCs, could be phased in quickly in order to comply with Montreal Protocol schedules. In several sectors, consideration of non-fluorocarbon solutions occurred. This started in 1992 with the development of isobutane as a refrigerant for domestic refrigerators in Europe and the consideration of carbon dioxide for several applications (initiated by the late Gustav Lorentzen). The "natural refrigerant" conversion became an important driver and in several refrigeration sectors new technological developments were started during the last decade. Next to carbon dioxide and HFC-152a, low-GWP alternatives were recently announced as HFC replacement for mobile air conditioning. The paper summarises a number of aspects involved: the Montreal and Kyoto Protocol regimes, reporting by TEAP and IPCC, the impact of regulatory frameworks, initiatives by industry and ENGOs, as well as technological and cost potentials and barriers. It summarises the current status and considers some ways forward.
