Small Country Creates Cooling System with Metal Alloys That Eliminates Toxic Gases and Could Transform the Global Market.
In a small country with fewer than 2.5 million inhabitants, an innovation could globally change the way we cool homes, offices, and even refrigerators.
Slovenia, known for its landscapes, is now at the forefront of a technological revolution that could reduce the global carbon footprint.
Slovenia Introduces Green Cooling Technology
Slovenian researchers recently revealed a new type of air conditioner that does not rely on harmful gases to cool the air.

Second large cruise ship built in China departs from Shanghai for testing with 937 professionals from 12 countries on board. Adora Flora City is 341 meters long, has 2,130 cabins, and a capacity for over 5,200 passengers.
The system uses nickel-titanium alloys, materials with a unique ability to generate cooling through mechanical deformation.
This system is part of a European initiative called SUPERCOOL and represents a radical departure from methods used for more than a century.
Currently, traditional systems use gases that evaporate or liquefy to generate cold. However, these methods contribute significantly to greenhouse gas emissions.
The innovation completely eliminates this problem. With a solid material that does not release harmful gases, the solution offers a much cleaner alternative for cooling, with potential for significant environmental impact.
Elastocaloric Principle: Simple Yet Revolutionary
Although it seems simple, the system could completely transform the cooling market, both residential and industrial.
The central principle of the new technology is the elastocaloric effect. In this phenomenon, metals like the nickel-titanium alloy cool down when mechanically deformed.
Unlike current systems, which depend on changes in the state of matter—from liquid to gas and vice versa—this new technology requires only mechanical deformation to generate cold.
This process is not only efficient but also environmentally friendly. Without toxic gases or harmful fluids, it eliminates risks of leaks detrimental to the environment.
Still in the prototype phase, the technology currently achieves an efficiency of 15%. Conventional systems operate with efficiencies between 20% and 30%.
However, considering that traditional compressors have had over a century of development, researchers believe that within ten years, the new system could compete strongly in the global market.
European Alliance Seeks to Bring Technology to Market
The project, named E-CO-HEAT, aims to bring this technology to the global market by 2026. Researchers have already partnered with companies in Ireland and universities in Germany and Italy to develop a functional prototype called SMACool.
The potential of the technology goes beyond laboratory limits. According to the International Energy Agency (IEA), air conditioning currently accounts for about 10% of global electricity consumption.
With the advancement of climate change and rising temperatures, this percentage is expected to grow rapidly, especially in developing countries, where the demand for cooling is increasing sharply.
The introduction of the Slovenian system could be an important step in curbing this increase in energy consumption.
A Sustainable Response to the Growing Demand for Air Conditioning
The expectation is that the number of air conditioning units will triple by 2050, especially in regions such as Asia, Africa, and South America. If current technologies continue to dominate the market, the environmental impact could be severe.
The Slovenian innovation, however, emerges as a cleaner and more sustainable solution, capable of meeting the growing demand without compromising the planet’s future.
The technology offers a silent, modular, and highly efficient alternative, with applications in various environments: from homes to data centers, electric vehicles, and household refrigerators.
The possibilities for use are vast, and if the project succeeds, the innovation could become a milestone in combating emissions and addressing climate change.
European Union Bets on Clean Heating and Cooling
The European Commission closely monitors the development of the technology. Within the Heating and Cooling Strategy of the European Union, an essential part of the European Green Deal, the bloc has committed to supporting research into technologies that reduce the environmental impact of cooling systems.
The system developed in Slovenia could become a key piece in helping the continent achieve its climate goals. With the global refrigeration market estimated to exceed € 1 trillion by 2035, both economic and environmental risks are enormous.
The next few years will be decisive in determining whether this technology can overcome the challenges of large-scale production and adoption across different sectors.
Small Country, Big Technological Advancement
Slovenia, despite its modest population, could be at the center of a global technological shift in the cooling sector.
The proposal presented by Slovenian researchers demonstrates how innovations can arise from small countries and impact international markets.
If established, this technology could be critical at a time when the world seeks urgent alternatives to curb the advance of global warming.
The Slovenian system, by not using harmful gases and relying on a simple mechanical process, could offer a balance between efficiency and sustainability, something current solutions have not yet achieved fully.
The technological advancement developed in Slovenia, based on the elastocaloric principle, proposes a new way to approach cooling.
By not relying on gases, with lower environmental impact and potential for global scalability, the innovation emerges in a scenario where the planet urgently seeks cleaner solutions.
The trajectory of this technology, from Slovenian laboratories to potential use in homes, industries, and vehicles worldwide, will still depend on the next steps of development, partnerships, and investments.
If successful, Slovenia could solidify its position as a global reference in clean cooling technology.
