Indigenous Green Refrigerant Technology

Why in News?

The CSIR-IICT, Hyderabad, has developed India’s first indigenous process technology for manufacturing next-generation green refrigerants.

• The Council of Scientific and Industrial Research-Indian Institute of Chemical Technology (CSIR-IICT) developed the laboratory-scale process platform for HFO-1234yf (a hydrofluoroolefin).
• They made it ready for commercial transfer to the domestic chemical industry.

HFO-1234yf

• It is a newly developed hydrofluoroolefin is regarded globally as the most promising green alternative to conventional cooling agents. \ 
• Zero Ozone Depletion - It has Zero Ozone Depletion Potential (ODP), meaning it causes absolutely no damage to the Earth's protective ozone layer.
• Negligible Global Warming Potential - It features an exceptionally low Global Warming Potential (GWP) compared to conventional gases.
• Ultra-Short Atmospheric Lifetime - While conventional Hydrofluorocarbons (HFCs) take 13.8 years to degrade in the atmosphere, HFOs break down in just about 11 days, drastically reducing long-term greenhouse accumulation.

Kigali is an international agreement that targets the phase-down of hydrofluorocarbons (HFCs)and India ratified the Kigali Amendment to the Montreal Protocol in 2021.
