Delphy Improvement Center: Advancing Research in Fossil-Free Horticulture

Skytree’s Cumulus is actively participating in Delphy Improvement Center’s innovative pilot project focused on cultivating peppers using fossil-free heat which is fundamental to their core areas of focus: precision agriculture.

Delphy Improvement Center is a leading consultancy and research organization dedicated to innovation in the horticulture industry. Based in the Netherlands, Delphy Improvement Center focuses on advancing sustainable practices, optimizing production, and addressing global challenges such as food security and climate change. Their expertise spans multiple sectors, including greenhouse horticulture, open-field crops, fruit cultivation, and floriculture.

Delphy Improvement Center’s research is pivotal in helping growers increase yields, improve crop quality, and reduce resource consumption. The organization operates research centers and trial facilities, where they test new technologies, cultivation techniques, and crop protection strategies.

Skytree’s Cumulus is actively participating in Delphy Improvement Center’s innovative pilot project focused on cultivating peppers using fossil-free heat which is fundamental to their core areas of focus: precision agriculture. 

The fossil-free heat trial is using data-driven insights to optimize growing conditions like temperature, humidity, and now CO2 captured from ambient air, ensuring efficient resource use.

The Skytree Cumulus started operating at the end of September and has captured more than 500kg CO2 in total since, which translates up to 12kg/day. This is aiding the pepper's growth in a controlled environment. The project will run until the end of 2024 and the initial results highlight the potential of utilizing captured CO2 to boost crop production and decrease reliance on fossil fuels.

By merging scientific research with practical applications, Delphy Improvement Center continues to play a crucial role in shaping the future of the horticulture industry, promoting a more sustainable and productive global food system. Research like this paves the way for our Stratus unit to be successfully implemented for larger-scale projects, perfect for the horticulture industry.

“During the month of October 2024, the Cumulus supplied part of the CO₂ required by the crops. It was an interesting project to demonstrate that CO₂ can be provided from ambient air in greenhouse horticulture. Additionally, we discovered that a sufficient supply of outside air is crucial for the machine’s efficient operation."
