EPA’s HFC Regulation Thrown Out by US Court


By Steve Schaeber, MACS Technical Editor

On August 8, 2017, a US District Court of Appeals reversed a 2015 EPA rule which removed R-134a from their SNAP list of acceptable substitute refrigerants for newly manufactured passenger cars and light trucks beginning with the 2021 model year (MY). The lawsuit was brought by refrigerant manufacturers Mexichem and Arkema back in 2015 shortly after the rule was first announced.

This reversal is a setback for advocates of climate protection and HFC reduction, including Chemours and Honeywell, manufacturers of R-1234yf refrigerant, the HFO which has been replacing R-134a in mobile A/C systems since 2012, and which is now being used in approximately 60% of all newly manufactured US vehicles and almost 100% of those currently being sold in Europe. The two companies, along with lawyers from the Trump Administration, helped to defend EPA’s position in court hearings back in February.

 

In their opinion, the court cited EPA’s authority under Section 612 of the US Clean Air Act Amendments of 1990. EPA’s 2015 HFC rule says that it can change the listing status of a refrigerant based on new information about its effects on human health and the environment. Since that information shows HFCs are highly potent greenhouse gases and major contributors to climate change, and alternatives are available which have drastically reduced effects, EPA setup a phase out schedule beginning with MY2021 and continuing until MY2025. But the court disagreed, saying that, “EPA’s authority to regulate ozone-depleting substances under Section 612 and other statutes does not give EPA authority to order the replacement of substances that are not ozone depleting but that contribute to climate change.”

 

Although they struck down this ruling, the court did offer EPA that it could still accomplish the same goal by using its authority under the Toxic Substances Control Act, or by using a “retroactive disapproval” approach. It’s now up to EPA to decide if it wants to appeal this court’s ruling (to continue to defend its authority as originally written back in 2015), or if it wants to simply start over, and write a completely new rule.

 

So what does this mean for the mobile A/C industry? We’ll have to wait and see what happens for now, but we can expect that those manufacturers who have already switched their vehicles over to use R-1234yf will continue to fill them with the gas. We may even continue to see vehicle platforms change over to yf in the coming years, as many are planned changeovers that are far along in the refresh or redesign process and which are unlikely to be reversed.

 

For some brands that have not yet made any changes to their US models (like Nissan, Infinity, Daimler, BMW, Porsche, Audi, Acura, and Lexus), we expect that unless EPA appeals this Court’s ruling (and wins), or revises the previous rule or even writes a new one, they will continue to use R-134a in their air conditioning systems perhaps even into the next decade.

 

There is also widespread support for the current changeover (and a lot of time and money has already been invested) by industry advocates, vehicle OEMs, Tier 1 suppliers, parts, tools and equipment manufacturers and distributors. Many repair shops and technicians have also invested in tools, equipment, education and training to work with the new refrigerant, too.

Tata Motors and MAHLE partner together to develop a prototype Secondary Loop Mobile Air Conditioning System on a vehicle


Tata Motors Limited and MAHLE, one of the world’s 20 largest suppliers to the automotive industry, have signed a joint development agreement for designing and developing a Secondary Loop Mobile Air Conditioning System (SL–MAC), under the aegis of United Nations Environment. MAHLE and Tata Motors, along with the Institute for Governance and Sustainable Development (IGSD), which is coordinating the project, received funding for developing the SL-MAC system from the Climate and Clean Air Coalition to Reduce Short-Lived Climate Pollutants (CCAC), a global initiative to support fast action and make a difference in the areas of climate, public health, and food and energy security (www.ccacoalition.org). This project envisages use and trial of environment friendly, low global warming potential (GWP) refrigerants HF01234yf (ASHRAE A2L) and HFC-152a (ASHRAE A2).

 

A team comprising of representatives of the California Air Resources Board (CARB), the Mobile Air Conditioning Society Worldwide (MACS), the National Renewable Energy Lab (NREL), MAHLE, Tata Motors, and IGSD reviewed the newly constructed SL-MAC system and the prototype at the MAHLE Behr facility in Lockport, New York, USA, on 7 April 2017.

A Tata vehicle based on a new generation platform for utility vehicles, consisting of a more complex architecture with front and rear air conditioning system, has been selected for this joint development program. The SL–MAC system will first be installed in the Tata utility vehicle as a prototype. In the SL-MAC system, the alternative refrigerants first cool a secondary fluid/coolant, which in turn cools the air to comfortable temperatures inside the vehicle cabin. This process allows the safe use of slightly flammable refrigerants that have a low GWP and in turn achieves high cooling capacity, minimizing the losses and achieving an optimized overall thermodynamic efficiency in the process. This is in contrast to the conventional mobile AC system, where the cabin air is directly cooled by the refrigerant HFC-134a, which is ozone safe but has a high GWP.

 

According to Dr. Tim Leverton, Chief Technology Officer, Tata Motors – “Tata Motors has been at the forefront of innovation and is constantly working towards shaping the future of mobility. As a part of our R &D efforts, we are committed to pioneering and inventing solutions to a greener future in the auto industry and this initiative is a step in that direction. We are the first OEM in India who is developing and evaluating an SL-MAC system on a car, using environmentally friendly refrigerants. We are delighted to work with class leading global suppliers like MAHLE and institutions like IGSD to contribute to the United Nations Environment initiative.”

 

The new SL-MAC system, which is testing the low-GWP refrigerants, is expected to increase vehicle energy efficiency through engineering. This system will turn off the compressor during acceleration and will retain coolness when the compressor is inactive or the engine is turned off for a short duration, allowing rapid cool-down at re-start. In addition to the expected energy efficiency benefits (fuel saving of up to 3%), the SL-MAC system allows the use of refrigerants that should avoid flow into the vehicle cabin. The refrigerant never enters the passenger compartment and instead stays in the engine area. Only the coolant circulates through the interior air conditioning unit.

 

According to Dr. Stephen O. Andersen, PhD, Director of Research for IGSD – “The Secondary Loop System will permit the use of alternative refrigerants like HFC-152a (GWP of 138) and HFO-1234yf (GWP<1) which have much lower GWPs than the current most-commonly used refrigerant, HFC-134a (GWP of 1300). We will be comparing the life-cycle carbon footprint of HFC-152a – with a higher GWP offset by higher energy efficiency – to the carbon footprint of HFO-1234yf and we will be estimating the cost of manufacture and ownership for each system”.

 

The SL-MAC project is on schedule, as expected, with anticipated environmental and cost advantages to be determined in the next stages. The prototype will be tested on the Indian roads later in the third quarter of 2017, where long seasons of hot and humid weather and stop-start driving conditions make a secondary loop air conditioning system highly advantageous.
