Honeywell, a global manufacturer of high-performance specialty materials and DuPont, a science-based company, announced last Thursday (May 20) a manufacturing joint venture to produce a new refrigerant for use in automotive air conditioning systems. The new refrigerant has 99.7% lower global warming potential (GWP) than the current refrigerant.
Under the agreement, DuPont and Honeywell will share financial and technological resources with the intent to jointly design, construct and operate a world-scale manufacturing facility for the new refrigerant, known as HFO-1234yf. The product meets European Union regulatory requirements for lower GWP refrigerants for automobile air conditioning systems. DuPont and Honeywell developed the product jointly but will market and sell it separately.

This venture follows an earlier joint development agreement under which the two companies developed the product. The joint venture announced is designed to provide DuPont and Honeywell with a world-class source of supply to meet the growing demand faster than would be possible through either company's individual efforts.

Today's automotive air conditioners use hydrofluorocarbon HFC-134a, which has a GWP of 1430. The European Union's Mobile Air Conditioning Directive requires that, starting in 2011, all new vehicle models use a refrigerant with a GWP below 150, and by 2017, all new automobiles sold in Europe will be required to use a low-GWP refrigerant. The new refrigerant, developed by DuPont and Honeywell, has a GWP of 4, which is 97% less GWP than the new regulation requires.

Prior to construction of a world-scale plant, the joint venture will begin supplying the refrigerant in the fourth quarter of 2011 in time to meet the European Union regulatory requirement.

Honeywell and DuPont introduced HFO-1234yf to the automotive industry in 2007, and since then, it has undergone extensive testing for safety and efficacy by independent testing groups such as the SAE International Cooperative Research Program, in which leading automakers participate.
