Compact heat storage system wins innovation award for energy solutions
Cowa Thermal Solutions has won the Clean Energy & Storage category at the Start Up Energy Transition (SET) Award 2025. The jury praised the fact that Cowa's compact thermal storage systems with thermodynamic materials are five times smaller than water-based systems.
The international jury of the SET Award 2025 has chosen Cowa Thermal Solutions as the winner in the Clean Energy & Storage category. The SET Award promotes innovative ideas and solutions for a sustainable energy future and thus accelerates the energy transition.
The competition is announced and organized worldwide by the German Energy Agency in cooperation with the World Energy Council. It is supported by the German Ministry of Economic Affairs and Climate Protection. The award recognizes innovations that drive forward the global energy transition. The award ceremony took place as part of the SET Tech Festival 2025 in Berlin.
As the organizers point out in a press release, Cowa is developing “compact heat storage systems with phase change materials that are five times smaller than water-based systems. With the aim of serving the growing European heat pump market, Cowa is improving the integration of renewable energy and urban energy efficiency.”
In a press release issued by his company, which was founded in 2019 and is based in Technopark Lucerne, Cowa CEO Simon Maranda describes this award as “a great recognition of our work and commitment to innovative energy storage solutions. Our compact thermal energy storage systems are an ideal solution for integrating renewable heating systems, especially heat pumps, in urban buildings with limited space. We are proud to continue to drive this technology forward and play an active role in shaping the energy transition.”
Once again this year, pioneering start-ups were honored in five categories: Clean Energy and Storage, Mobility & Transportation, Industry, Buildings & Construction and Access to Quality Energy & SDG-7. The winners of all five categories also presented their solutions at the Berlin Energy Transition Dialogue afterwards.
