Stiesdal SkyClean is a specialised technology provider dedicated to carbon capture via pyrolysis. SkyClean pyrolysis plants convert organic by-products from agriculture, forestry, and industry into biochar and bioenergy.
Pyrolysis is a well-established process that has been used for millennia to produce biochar.
Building on research conducted at the Technical University of Denmark (DTU), Stiesdal SkyClean has developed this ancient practice into a modern, industrial technology designed to produce high-quality biochar suitable for application on agricultural land.
By converting biomass into a stable form of carbon that can be stored in soil for centuries, Stiesdal SkyClean’s pyrolysis process enables durable CO₂ removal, while generating renewable energy as a co-benefit.
The Stiesdal SkyClean leadership team brings extensive experience from the Danish wind industry, combined with a focus on innovation and scale. This background informs the company’s approach to carbon removal: applying engineering expertise and industrialisation know-how to deliver complex energy systems at scale.
