Kas als Energiebron has published the first results from Skytree's Cumulus trial at Bleiswijk Innovation Center and they match the industry's standard OCAP Pipeline System.

The unit has captured and supplied over 1,660 kg of CO₂ to cucumbers over 166 days. These are promising results for the future of DAC in Dutch greenhouse horticulture.

As part of Wageningen University & Research's (WUR) pilot program "Kas als Energiebron" the Innovatie- en Demonstratiecentrum voor CO₂ uit Buitenlucht (IDC-CO₂) (IDC-CO₂) is conducting two trials to explore the capacity of various Direct Air Capture (DAC) technologies for providing a sustainable CO₂ supply to a cucumber greenhouse. Skytree’s Cumulus Unit is participating in this initiative.

The report from the first trial, which took place from January to June 2024, has been published by Kas als Energiebron, and we are proud to see that our Cumulus achieved promising results: 71 kg/m² cucumber yield over 166 days. These figures match the industry-standard OCAP pipeline system, demonstrating how Direct Air Capture (DAC) can support a reliable CO₂ supply in a world transitioning away from fossil fuels.

Another interesting topic is that no phytotoxicity was found. Only marginal NOx which are being attributed to external conditions.

This research lays the groundwork for our next generation of greenhouse-specific Stratus units, optimized for CO₂ needs on a larger scale. We are proud to pioneer this sustainable solution alongside WUR and the Kas als Energiebron program. We are getting ever closer to a circular, CO₂-neutral future for greenhouse horticulture!
