GE (NYSE: GE) announced today that it has submitted information to the Environmental Protection Agency (EPA) in connection with a request for approval to use isobutane as a refrigerant in household refrigerators.
The petition was filed under the Significant New Alternatives Policy (SNAP) program which evaluates alternatives to substances being phased out under the Clean Air Act for protection of the stratospheric ozone layer.
Isobutane has been widely used in household refrigerators in Europe and parts of Asia for several years. EPA approval for the use of isobutane in U.S. household refrigerators would allow, for the first time, use of a hydrocarbon refrigerant as a substitute for hydrochlorofluorocarbon (HCFC)–based refrigerants now widely used in the U.S. Using hydrocarbon refrigerants would result in a lower global-warming impact, according to GE.
Upon gaining EPA approvals, GE plans to include isobutane in a a new refrigerator currently in development for introduction in early 2010. The refrigerator also will be made using cyclopentane, another hydrocarbon, as the insulation foam-blowing agent to replace commonly used HFC foam blowing agents.
GE plans to begin test marketing HFC-free refrigerators in select locations later this year. Conversion of the household refrigerators to hydrocarbon refrigerants will be dependent on EPA approval and favorable public policy supporting the transition, the company said.
"The approval of isobutane under SNAP will pave the way for the use of low-GWP refrigeration technology in the U.S. to help address global warming challenges. A refrigerator with lower GWP emissions will allow consumers to reduce their carbon footprint," said Kevin Nolan, Vice President of Technology for GE Appliances.
According to Drusilla Hufford, Director of EPA’s Stratospheric Protection Division, "EPA welcomes GE’s decision to apply for SNAP review of this hydrocarbon refrigerant for household refrigerators, which will be carefully considered by EPA both in terms of its safety and environmental attributes. The environmental gains that have already been realized in the transition from ozone-depleting substances such as CFC-12 under the Montreal Protocol have been dramatic. Should EPA reach a favorable determination on this SNAP submittal, this could be part of the next important step in the market’s transition to more environmentally friendly refrigerants."
"The fridge for the 21st century must use less energy and run on refrigerants that don’t add to global warming, while meeting all safety standards," said David Doniger, climate policy director for the Natural Resources Defense Council. "The companies that win will be those that bring these smarter, cleaner, and safer products to market, and build them here in America. GE is taking an important first step to making the use of efficient, low-GWP refrigerants a reality."
