Alexis Sevault shows off the award right after Cartesian was named winner of the Nordic Innovation Award 2025.

Norwegian Cartesian wins Nordic Innovation Award

The award is new this year and has been established by the patent offices of Sweden, Denmark, Finland, Iceland and Norway. During the final in Copenhagen on April 10, the Trondheim company Cartesian emerged victorious ahead of the other Nordic candidates.

Cartesian has developed a thermal box that saves energy and reduces CO2 emissions. They sell this to commercial buildings, thereby contributing to more sustainable energy consumption.

Technology based on phase changes in the material

The technology is based on the principle of absorbing and/or releasing thermal energy by using the phase change of a material, so-called PCM material (Phase Change Material) . This can store large amounts of energy per unit volume. The use of PCM material allows the systems to be adapted to temperatures from -20 to 120 degrees by choosing a PCM that is adapted to a specific temperature level (the phase transition).

The modular design of Thermal Box allows the solution to be easily integrated into heating or cooling systems in commercial buildings and scaled and adapted to customers' different needs.

Cartesian has four installations in Norway and France, and has several projects scheduled for delivery in 2025.

Will ensure a better future

Sune Stampe Sørensen, director of the Danish Patent and Trademark Office and member of the Nordic jury, says:

– We need innovative and effective solutions to the major challenges in climate, health and society, so that we secure a better future for future generations. At the same time, with the Nordic Innovation Award, we recognize companies' use of intellectual property rights such as patents, trademarks and designs, which help turn good ideas into profitable businesses – to the benefit of both society and us all.

We congratulate Cartesian on their victory!
