Sustainable energy production

(the Swedish way)

Creating a new generation of sustainable energy

Cleanergy is the world’s leading supplier of sustainable energy solutions based on the stirling engine.

Our Combined Heat & Power (CHP) and Concentrated Solar Power (CSP) systems are today benefitting customers from Inner Mongolia to the UK, enabling them to generate gas and solar-based energy more sustainably; more efficiently; and more profitably.

It’s all thanks to an engine system invented nearly 200 years ago that has been reinvented for the 21st century to run on solar heat and (otherwise) wasted gas.


Stirling yesterday, today, and tomorrow

Cleanergy was founded in 2008 when we acquired the rights of the V 161 stirling engine from Solo Kleinmotoren GmbH of Germany.

Fortunately, we not only acquired the technology, but also the veteran team behind it. Thanks to our unique blend of knowledge, materials and processing expertise we are now poised to make sustainable stirling energy solutions a major, lasting part of global energy generation.

From landfill sites to solar parks, our engines are today installed at more than 100 locations around the world and have accrued some two million operating hours and counting.

All of which makes us the undisputed leader in stirling energy solutions for solar and gas.

Standing on the
shoulders of giants

Manufacturing excellence

The Cleanergy operation is built on the foundations of Swedish automotive excellence – literally.

Our high-volume production facility in Uddevalla, Western Sweden was formerly owned by Volvo. It’s built around the latest lean manufacturing principles and is supported by a network of automotive-grade suppliers and partners.

For our customers this guarantees quality, reliability, consistency – and security of supply.

Further afield we have offices across Northern Europe and have been established ‘on the ground’ in China since 2011 – as well as a strategic partner network that covers not just China, but Russia, Canada, US, and many European countries.
