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.

Hydrofluorocarbons (HFCs)

Hydrofluoroolefins (HFOs)
|
- Hydrofluorocarbons (HFCs) were originally introduced to replace ozone-depleting substances, they turned out to be extremely potent greenhouse gases.
|
- Hydrofluoroolefins (HFOs) are unsaturated HFCs containing double bonds, which make them highly reactive and quick to dissolve in the lower atmosphere without triggering climate warming.
|
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.
