Ford is pioneering a new era of eco-friendly and efficient EV climate control by exploring the use of propane (R290) in its HVAC systems. This innovative approach promises to enhance EV performance while minimizing environmental impact. By proactively addressing concerns related to traditional refrigerants, Ford is demonstrating its commitment to sustainable automotive technology and setting a new standard for the industry.

The shift towards propane-based systems is driven by concerns surrounding the breakdown of R1234yf, a widely used refrigerant that can produce trifluoroacetic acid (TFA), a substance linked to potential health and environmental risks. Ford’s application to the EPA to list R290 as an acceptable alternative under the SNAP program reflects the company’s dedication to finding safer and more efficient solutions. Ford’s research indicates that R290-based full-secondary loop heat pumps offer significant performance benefits compared to other technologies, potentially improving EV range and overall efficiency.

This move aligns with global efforts to phase out harmful refrigerants, as evidenced by the European Chemicals Agency’s upcoming discussions on potential restrictions for R1234yf. Ford’s proactive approach in exploring R290 demonstrates its leadership in anticipating and addressing environmental concerns. By adopting this technology, Ford aims to provide customers with EVs that are not only high-performing but also environmentally responsible.

The potential benefits of R290 extend beyond environmental considerations. As Kristen Taddonio, Senior Technical Advisor to IGSD, notes, this technology can “safely cool and heat electric vehicle occupants while increasing electric vehicle driving range, which is key to satisfied customers.” Ford’s focus on enhancing both performance and sustainability underscores its commitment to delivering innovative solutions that meet the needs of today’s drivers and protect the planet for future generations.
