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.

ESA Spinout Technology

Skytree is a spinout of the European Space Agency (ESA). Our CO2 re-capture process was originally developed to make longer space missions possible by extracting the CO2 exhaled by astronauts on board of spacecraft.

Our technology was developed as part of a long-term project launched in 1996, and with a total budget of € 70 million. It will be implemented at the International Space Station in 2017.

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.

Skytree ® patents

Currently Skytree owns two process patents that were granted in the period 2013-2015 and are based on in-house testing. The European Patent Office approached Skytree to make this video about the process of filing these patents as part of their effort to promote space-technology spin outs.

As of 2016 Skytree has two additional patents pending.


Our founders met at the European Space Agency 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.
