Skytree Cumulus

Science Park 301, 1098 XH Amsterdam, Netherlands
Founded in 2014 and headquartered in Amsterdam, Skytree harnesses CO2 from ambient air through the power of direct air capture technology (DAC). By providing local, onsite CO2 generation across multiple markets including indoor farming, greenhouses as well as mineralization, Skytree enables a transition away from fossil fuel-based industrial processes and avoids transport to where the CO2 is needed.  The company’s core technology captures CO2 from ambient air and stores it in pressurized buffer tanks where it can be accessed for multiple applications. The modular technology can be set up quickly at any location and scaled to meet the needs of businesses of all sizes.
