A new study demonstrates that HFC-23 (CF3H) is not formed during the decomposition of HFOs and HCFOs in the troposphere
Most HFOs and HCFOs decompose in the atmosphere via an intermediate product which then breaks down further. The breakdown of the intermediate product CF3CHO (trifluoroacetaldehyde) has been investigated as early as the 1990s. In 2021 EFCTC published an analysis of the atmospheric degradation of this intermediate, which can occur via three routes.…

F-Gas Regulation and shift to lower GWP F-gases – a pause before the next phase-down step
The data available in the latest EEA report, in 2020 shows there was very little change in total supply of HFCs and HFOs/HCFOs compared with 2019. The considerable changes in HFCs and HFOs/HCFOs use patterns since 2014 demonstrate the progress delivered due to the F-gas regulation. It is not surprising…

The case for a large natural source of TFA in the oceans is extremely strong, well-documented, and scientifically supported
The generally accepted conclusion is that trifluoroacetate (TFA) does occur naturally, in part based on the undisputed large quantities of TFA in the oceans. Surprisingly, the recent review paper “Insufficient evidence for the existence of natural trifluoroacetic acid” by Joudan et al. [1] concludes that “the presence of TFA in the deep ocean…

Chiller and Heat Pump innovations with F-gases deliver improved performance
Innovations for chillers and heat pumps using HFOs and HFCs, and their good balance of safety and technical properties, continue to deliver improved performance and reduced energy consumption. While ultra-low GWP HFOs and HCFOs are increasingly being adopted, HFCs continue to have an important role in reducing energy consumption, including for data centers.

Presentations on refrigerants, TFA, and atmospheric degradation at the German Refrigeration and Air Conditioning Association (DKV) Annual Conference
The EU PFAS Registry of intention (ROI) has reignited the discussion on fluorinated refrigerants and TFA, an atmospheric degradation product. The German Refrigeration and Air Conditioning Association (DKV) had a dedicated session covering a wide range of issues at their annual conference in November 2021.…
