Refrigerant gases are undergoing a rapid transition as the industry moves away from older, high-global warming potential (GWP) formulations toward newer alternatives with a lower climate impact.
That shift is being driven by a mix of regulation, system efficiency concerns, and growing expectations around circularity and end-of-life treatment.
“In a perfect world, we’d use the most efficient refrigerant gases and would have no emissions,” said Stephen Harrison, founder of sbh4 Consulting, who spoke on a recent gasworld webinar. “However, the production, maintenance, and end of life treatment of refrigeration systems causes some gas losses.”
It is essential, he says, to convert these gases to new ones with a lower GWP. These include HFOs – new generation refrigerants developed to replace older refrigerants like HFCs – and natural refrigerants.
