Lifetime Cost of Energy = 0,012 €/kWh.

Globally Stored Thermal Solar Energy, the new solution.

The Stirling engine has never had commercial success, but within cryogenic cooling. That is what we utilize.

We generate a cryogenic cold side in the process, making it possible to utilize ambient heat and low temperature waste heat with high thermal efficiency.


This has been made achievable through extensive archive material made available to us from the Stirling R&D at Lund University in Sweden, through our R&D-cooperation with the Norwegian University of Life Sciences at Ås, Norway.


Like the piston engine Brayton Cycle being transformed to Jet Engine, our “Stirling” have made a similar transition, to a modern high power to weight/volume ratio engine solution.


The Stirling conversion of ambient heat to work, with an artificial cold side and piston Stirling Engine, was first demonstrated at our lab at the Norwegian University of Life Sciences in 2013, with too low power to weight/volume ratio. This technology was therefore deemed not efficient enough for commercial applications.

In the picture below an early one stage non-piston version of the technology generates a cold side 39K below the ambient temperature of 9oC (2014, 2015 and 2016).

Demonstrating full and instant adjustable power supply and constant frequency/voltage.

Providing balance power, eliminating wind and solar grid power challenges.

Prototype platform being a Norwegian Nordkapp-class scale ship.

Adaptable to electric vehicles, buildings etc.

The technology has been developed to accommodate different application platforms, like electric cars and trucks, railway, ships and airplanes, to generate practically unlimited range without batteries.

All to be demonstrated through the multinational R&D-program in France.

Nature is our battery.
