DuPont and Honeywell have announced they will build the first production facility for the automotive refrigerant
HFO1234yf in Zhonghao, China, continuing the collaboration started during its development.
The firms will start supplying the gas from the fourth quarter of 2011. This plant will be a transitional facility, ahead of a large-scale plant to be built in 2015 at a location to be decided.
Under the agreement, DuPont and Honeywell said they “will share financial and technological resources with the intent to jointly design, construct and operate a world-scale manufacturing facility for the new refrigerant.”
DuPont and Honeywell developed the product jointly but will market and sell it separately. HFO1234yf has a
global warming potential of 4 than the current refrigerant, R134a (which has a GWP of 1430), which will not be allowed in new cars from 2011 under the European Mobile Air Conditioning (MAC) Directive.
The Mac Directive requires that from January 2011, all new vehicle models use a refrigerant with a GWP below 150.
Honeywell said that while it would not have production-scale gas ready in time for that date, it believed its timescales would be well-placed for the traditional launch of new car models in mid-2011.
