Environmentally Applied Refrigerant Technology Hub



Industry Descends on EARTH

More than 100 people gathered for EARTH's industry forum to discuss the future of the heating, ventilation, air conditioning, and refrigeration (HVACR) industry. Interested in our government-academia-industry partnership?

ERC Overview

EARTH is founded on four ERC pillars: convergent research, impact and belonging, engineering workforce development, and innovation ecosystem, which will impact the engineering and scientific communities, the HVACR industry, and society.

The Challenge

Heating, ventilation, air-conditioning, and refrigeration (HVACR) are essential to the quality of life for all humans. HVACR systems are widespread throughout society, enabling transportation and preservation of fresh foods, storage of medicines, and cooling of buildings. However, most refrigerants used today are hydrofluorocarbons (HFCs), which have high global-warming potential (GWP), with 2000-4000 times the impact of CO2. Combined with high leak rates (direct effect — 50-90% of refrigerants leak into the atmosphere) and high energy consumption (indirect effect — 20-40% of U.S. residential and commercial building electricity usage comes from HVACR), HFCs account for 7.8% of total greenhouse-gas emissions. In response, the U.S. and 170 other countries are phasing down HFCs in accordance with the Kigali agreement, F-gas regulations, and American Innovation and Manufacturing (AIM) Act, creating a tremendous societal challenge to responsibly and sustainably replace billions of kilograms of refrigerants.

To address this challenge, a multi-institution, multi-disciplinary team put together a new NSF Engineering Research Center (ERC): Environmentally Applied Refrigerant Technology Hub (EARTH), to create a “sustainable refrigerant lifecycle” to address technical, environmental, and societal challenges facing the HVACR industry.

Our Vision

EARTH will create sustainable, accessible refrigeration and air conditioning innovations that improve the quality of life for all, address current and future environmental challenges, and secure U.S. leadership in workforce development and manufacturing.

Reclamation & Repurposing

Promote the recycling of refrigerants (e.g. billions of kilograms are in use today) so that blend components can be recovered as pure compounds and reused in new more environmentally friendly formulations or repurposed into new materials that are environmentally safe and uniquely functional.

Novel & Safe Refrigerants

Develop “transformative refrigerants” that have a balance of properties such as environmental, toxicity, flammability, stability, energy efficiency, system complexity, price, recyclability, and long-term availability.

Energy Efficient Systems

Develop next-generation cooling technologies with higher energy efficiency than current vapor-compression technologies using high fidelity experiments, advanced atomistic simulations, data science methods, and rigorous process design.

Our Mission

EARTH will serve as the national refrigerant research center that will enable the refrigeration and air conditioning industry, federal government, policymakers, and professional and environmental organizations to (1) innovate future system technologies to utilize highly efficient and safe refrigerants with low environmental impact; (2) develop and implement new practices for effectively reclaiming, separating, and recycling refrigerants; (3) invent novel processes for converting legacy refrigerants into future products; and (4) support the education and training of an impactful workforce.

Our Policy and Impact

  • Current refrigerants (Hydrofluorocarbons or HFCs) will be phased out according to the American Innovation and Manufacturing (AIM) Act passed by Congress and signed by the president in Dec, 2020 due to high global warming potential (GWP)
  • Montreal Protocol, Kigali agreement and European F-gas regulations requiring similar phaseout of HFCs in 170 countries
  • Phase out of HFCs over next two decades is estimated to create 150,000 new jobs, increase manufacturing by $39 Billion in the U.S., and reduce global temperature rising by 0.5 ºC
  • Refrigeration and Air-Conditioning (RAC) accounts for 20% of U.S. energy consumption
  • RAC industry is strategic to U.S. national interests – maintain export market

EARTH: A New Way to View the Blue Sky

When Irish physicist John Tyndall was conducting research on why the sky is blue, he explored the notion with awe, for the pure sake of the idea. As he performed his experiments at The Royal Institution in London, in 1869, he likely did not foresee that his work would inspire generations of scientists and entrepreneurs who would adopt the term “blue sky” to explain the tenets of basic research.

Industry Descends on EARTH

EARTH, an Engineering Research Center funded by the National Science Foundation and corporate investment, is hosting on October 20 an Industry Forum at the University of Kansas. Attendees will discuss the academic research, market potential, and rise of AI that are fueling advances in HVACR (heating, ventilation, air conditioning and refrigeration).

A new use for old refrigerants

Chemicals in air conditioners are thousands of times more dangerous for the environment than tailpipe emissions from cars. Researchers at Lehigh University are working to change that. David Vicic, Howard S. Bunn Distinguished Professor of Chemistry at Lehigh University, recently announced a breakthrough in chemical research: His team used the metal iridium to functionalize hydrofluorocarbon refrigerants – the ubiquitous chemicals that cool refrigerators, medicines, homes, and office buildin
