ShareSlovenian researchers explore solid-state cooling to replace harmful refrigerants
A breakthrough technology using metal alloys may offer a safer, greener alternative to conventional cooling systems.
A team of researchers at the University of Ljubljana in Slovenia is developing a new form of solid-state cooling that could eliminate the need for toxic refrigerants in conventional cooling systems. Instead of using vapor-compression cycles, the method relies on metal alloys like nickel-titanium that cool down when mechanical stress is removed – a process known as elastocaloric cooling.
Led by assistant professor Jaka Tušek, the team is building on the EU-funded SUPERCOOL project, with further development underway through the E-CO-HEAT initiative. Though still in its early stages, the prototype already demonstrates promising potential for a quieter, more efficient, and environmentally friendly alternative to traditional systems.
With global demand for cooling expected to triple by 2050, finding sustainable solutions is becoming increasingly urgent. The researchers are working on industrial partnerships and patent development to move the technology closer to market.
