About Us

Cleanergy is the world’s leading supplier of sustainable energy solutions based on the Stirling engine with it's main focus on dispatchable , on-demand solar electricity. Cleanergy AB is a Swedish high-tech SME specialized in the supply of Stirling engine-based renewable energy solutions. The company has its headquarters in Gothenburg and production facilities located in the heart of the Nordic automotive and aerospace clusters on the west-coast of Sweden. The Stirling engine is produced in a state-of-the-art assembly line. Cleanergy has access to the most advanced material suppliers and engineering centres of excellence in Northern Europe. Cleanergy’s forthcoming solution for multi-hour energy storage is expected to be substantially cheaper than competing technologies for dispatchable solar electricity. The cost advantage stems from a combination of two technologies. The first is Cleanergy’s field proven and highly efficient Stirling engine. This technology utilizes the thermal energy, or heat, from the sun to run Stirling engines equipped with generators. This process converts much more of the sun’s energy to electricity than established technologies. The second advantage is the storage of thermal energy at a fraction of the cost of storing electricity.
