About Skytree

Our mission is to establish atmospheric CO2 use in everyday life. We hope to initiate a positive shift in people’s perception: from CO2 as a potential problem to CO2 as an essential and incredibly versatile resource.


Our founders met at the European Space Agency (ESA) in 2008 where they were working as system engineers on the life-support project for the International Space Station, studying what would ultimately become Skytree’s technology.

Today Skytree is self-sustainable and generates (licensing) revenue through co-development projects on useful & scalable products for leading companies within industry. We are also supported by investment fund InvestInFuture.

Direct Air Capture

Skytree is part of the Direct Air Capture (DAC) industry, which represents a technological solution when it comes to climate change because it can directly remove CO2 from the Earth’s atmosphere.

Technology & patents

Our CO2 re-capture process was originally developed by ESA to make longer space missions possible by extracting the CO2 exhaled by astronauts on board of spacecraft.

This technology was developed as part of a long-term project for the International Space Station and was launched in 1996 with a budget of over €70 million.

Currently Skytree owns 2 process patents that were granted in the period 2013-2015 and are based on in-house testing. As of 2016 Skytree has 2 additional patents pending.
