Cleanergy AB

Cleanergy AB was established in 2008 by a number of Swedish investors with many years of experience in both industrial businesses as well as entrepreneurship. In 2008 the company carried out the acquisition of production equipment, stock-in-trade, spare parts and a comprehensive patent portfolio as well as other intangible assets for a stirling engine.

Based on the comparisons, the company sees a significantly lower need for service for Cleanergy's engine. The service cost was estimated to be approx. 30 % in comparison with the Otto engine and approx. 33 % in comparison with the diesel engine. The cost of the energy delivered during a 10-year period is estimated by the company to be approx. 64 % in comparison with the Otto engine and approx. 82 % in comparison with the diesel engine.

Cleanergy's stirling engine has an efficiency of between 22-30 % as well as high operating reliability that was demonstrated in test conditions during more than 24,000 hours for an individual engine. The tests show an availability that amounts to 95 %.
