Cooling technologies haven’t changed much in over a century — and that’s a big problem in a warming world. Traditional systems like fridges and air conditioners still rely on outdated vapor-compression methods and harmful chemicals. Even newer refrigerants, such as hydrofluorocarbons, have turned out to be potent greenhouse gases. Now, a team of EU researchers led by Slovenian engineer Jaka Tušek is developing a groundbreaking alternative: a clean, efficient cooling system that uses recyclable metals instead of toxic gases.
The technology, developed at the University of Ljubljana, is based on a process called elastocaloric cooling — where certain metal alloys like nitinol heat up when compressed and cool down when pressure is released. This solid-state method could drastically cut emissions, operate more quietly, and avoid the environmental downsides of traditional systems. After solving key durability issues, the team has built a working prototype with a 30°C temperature range and a potentially unlimited lifespan. Collaborations across Europe are now accelerating development, with a market-ready version expected within the next decade.
For businesses working on climate solutions or breakthrough technologies, protecting innovation is just as important as creating it. At IP Solved, we help innovators turn their ideas into protected assets — whether you're developing next-gen cooling tech or something else entirely.
