Creating CO2 solutions

Skytree units filter CO2 from outdoor and indoor air and dispense it in concentrated form. Our CO2 supply is clean, adjustable and continuous.

Linked to a power source, our units can operate anywhere: in the middle of the ocean, in the desert, or at the heart of a city.

Skytree units have a wide range of applications: from improving plant growth to water treatment and fuel synthesis.

Our core competency is the transfer of our Direct Air Capture technology to products and applications on the small to medium scale and bring these to the market by establishing licensing partnerships with leading companies within industry.

Building a sustainable future

More than 4 billion people live in cities, a figure that is expected to double by the end of the century. This growing urban population needs access to clean air, water, food and energy.

Capturing excess CO2 from the air is only the first step. At Skytree, we turn this waste stream back into the useful resource it is: to grow fruit and vegetables, to clean drinking water, or to be transformed into energy for your home. Skytree creates practical CO2 solutions for everyday life.

Using ESA technology

Skytree is a spinout company 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 uses plastic beads that attract CO2 to their surface and release it when using low-grade heat (below 80 °C).
