We believe
in the sun

Azelio was born from the conviction that the future can be powered by solar energy. Determined to break down the last barrier we have relentlessly worked to find an economically attractive and sustainable way of storing solar energy so that it can be tapped when and where it's needed.


A new company with a strong industrial heritage

Azelio was founded in 2008 under the name Cleanergy by four Swedish entrepreneurs that shared a strong interest in environmentally friendly technology and renewable energy.
By buying the rights from a German company and securing the technology, they laid the foundation for a company that would focus on clean energy production based on the Stirling engine technology.

Since then over a 100 million USD have been invested in the company and Cleanergy has put proven and commercial demonstration units – the Dish Stirling CSP system – in locations all over the world. Constantly increasing the efficiency for every new installation.

In early summer 2018, when introducing the new ground-breaking thermal energy storage solution to the world, Cleanergy changed the name of the company to Azelio.
