Skytree is a Netherlands-based spin-off from the European Space Agency (ESA) that has developed decentralized direct air capture (D-DAC) technology, which can be used for indoor farming, building air filtration, water treatment, and energy storage. The company aimed to capture 10 million tons of CO2 by 2030.
Skytree’s modular D-DAC machines absorb CO2 from ambient air and release it in a pressurized stream in controlled environments. The company has developed “Skytree Cumulus” for vertical farms and “Skytree Stratus” for larger applications such as greenhouses. These provide sources of concentrated CO2, which boost crop yields in controlled environment agriculture by up to 20%–30% compared with traditional farming methods.
Skytree currently holds 17 patents across the US, Europe, and China for its carbon removal process. In July 2022, Skytree deployed its first DAC unit at Growy Farms, a Netherlands-based vertical farming company. In March 2024, the company unveiled Its second decentralized DAC unit, Skytree Stratus. In July 2024, Skytree followed up with the launch of the Skytree Stratus Hub for the mass deployment of DAC systems.
Key customers and partnerships
In December 2022, Skytree partnered with Plug and Play Japan to expedite the company’s footprint in the APAC region with Japan. In March 2023, the company partnered with the HortiHeroes startup program to gain insight into vertical farming industries and network with industry experts and knowledge institutions.
In April 2024, Skytree partnered with Deep Sky, a Canadian carbon removal project developer, to pilot Skytree Stratus at Deep Sky Labs.
Funding and financials
In November 2023, Skytree was awarded EUR 2.5 million by the European Innovation Council Accelerator. In June 2023, it raised USD 6 million as the second tranche of its seed funding round co-led by Horticoop and Yield Lab Europe.
