2024 has been an exciting year of growth and innovation for Skytree as we continue to push the boundaries of direct air capture (DAC) technology to capture CO₂ directly from ambient air and utilize it in a circular way to create valuable products or permanently store it to reduce atmospheric concentrations. With growing global demand for both removal and utilization, Skytree has focused on innovation, building strategic partnerships, and international expansion to accelerate DAC deployments. This timeline highlights the key milestones we achieved throughout the year, demonstrating our commitment to addressing emissions from hard-to-abate sectors and helping offset historical emissions.

Q1

Wageningen University & Research Test

‍Skytree partnered with Wageningen University & Research to test our DAC units in greenhouse environments. The trial assessed DAC’s ability to deliver clean, sustainable CO₂ directly onsite, eliminating the need for fossil-fuel-derived CO₂. Results demonstrated improved crop growth and energy efficiency, showcasing DAC’s potential to enhance controlled environment agriculture while reducing emissions. The project also explored scalability for larger greenhouse operations, positioning DAC as a viable solution for fossil-free horticulture. 

‍Launch of Skytree Stratus

‍We announced the launch of the Stratus DAC unit, designed for CO₂ utilization in various industries such as controlled environment agriculture (CEA), food & beverage, and water treatment. The Stratus generates up to 2,200 lbs (1,000kg) of CO₂ per day, reducing industry reliance on fossil-fuel-derived CO₂. Its modular design allows for scalability into Stratus parks to meet larger volume demands, with hybrid energy options ensuring efficiency and cost savings.‍

Q2

Deep Sky Labs

‍Skytree announced its partnership with Deep Sky, one of the largest carbon removal projects globally. The collaboration includes deploying Skytree’s Stratus unit in Alberta, Canada, using renewable hydroelectric energy. The CO₂ captured will be geologically sequestered to support Canada’s net-zero goals. Deep Sky and Skytree will also explore scaling up to a Skytree Stratus DAC park as part of the evaluation phase at Deep Sky Labs. A Skytree DAC park consists of multiple Stratus units, each with a capacity of 900 tonnes per year, and can be installed to accommodate any CO₂ site capacity requirement.

‍Purolite Partnership

‍Skytree signed multi-year development and supply agreements with Purolite, an Ecolab company and leader in purification resins. This collaboration focuses on creating next-generation CO₂ capture materials that increase capture capacity, improve energy efficiency, and lower the cost per ton of CO₂ captured. Purolite will serve as the sole resin supplier for Skytree’s DAC technology, enabling broader adoption and immediate customer benefits while advancing our mission to combat climate change.

‍Q3

Neboda Farms Deployment

‍We deployed our Cumulus unit at Neboda Farms to provide clean, sustainable CO₂ onsite. This deployment supports precision agriculture, optimizing crop yields while lowering emissions and reducing reliance on fossil fuels. The project highlights DAC’s role in enabling sustainable farming practices.

‍Scanfil Partnership

‍To meet rising global demand, Skytree partnered with Scanfil to scale the production of our Cumulus units. This partnership ensures reliable, high-quality manufacturing and supports Skytree’s expansion into new markets, enabling the widespread adoption of DAC solutions.

‍Q4‍

‍Delphy Improvement Center Pilot

‍Skytree completed a fossil-free greenhouse pilot at the Delphy Improvement Center in the Netherlands, testing CO₂ generation for pepper cultivation. The project demonstrated DAC’s ability to deliver reliable and sustainable CO₂, reducing emissions while maintaining crop productivity in controlled environment agriculture.

‍North America Expansion‍

We established our offices in Toronto and Nashville, strengthening our North American presence. This expansion supports Skytree’s regional deployments, enhances customer service, and helps scale our DAC technology for industrial and agricultural applications.

‍Winterization Review

‍In collaboration with Copenhagen Energy Partners, Skytree conducted a winterization review of its DAC systems. The tests ensured reliable performance in cold climates, enabling deployments in harsh environments and broadening the operational range of Skytree’s solutions.

‍Project Concho Announcement 

‍Skytree announced its role as the technology provider for Project Concho, the world’s first DAC hub powered entirely by wind energy. This pioneering project will combine Skytree’s advanced DAC technology with new wind power and onsite geological carbon storage to permanently remove CO₂ from the atmosphere. When fully operational, Project Concho will initially capture 30,000 tons of CO₂ annually, with plans to scale up to 500,000 tons per year. 

‍ReCarbn Acquisition

‍Skytree acquired ReCarbn, solidifying our technological dominance in the DAC and CO₂ generation markets. ReCarbn’s talent and innovative technology will enable us to deliver more cost-effective DAC solutions that make carbon capture more accessible to businesses around the world.

‍

As 2024 comes to a close, Skytree has made significant progress in advancing our DAC technology. We have focused on improving CO₂ capture materials, expanding manufacturing capabilities, and establishing a stronger presence in key markets. Projects like Project Concho and the acquisition of Recarbn highlight our efforts to scale solutions and support climate goals. We have more projects underway and look forward to sharing updates in the new year.
