Abstract: The greenhouse horticulture sector faces the significant challenge of eliminating fossil CO2 emissions in the long term. At the same time, CO2 remains essential for maximizing the photosynthetic capacity of plants. Direct Air Capture (DAC) could serve as a new CO2 source, but its functioning, integration into greenhouse operations, CO2 quality, and required inputs for such systems are still largely unknown. The IDC CO2 project provides a platform for the independent evaluation of DAC technologies, providing insight into the potential contribution of these systems to the sustainability of greenhouse horticulture. As part of the project, several DAC companies deploy their systems in the greenhouse facilities of Wageningen University & Research in Bleiswijk. The research aims to collect data in a semi-practical setting to: 1) assess CO2 quality and identify potential phytotoxicity risks, 2) evaluate performance in terms of production capacity, concentration, and energy efficiency 3) quantify necessary inputs such as sorbents and analyse outputs and 4) explore practical implementation challenges and opportunities. This report presents the key findings from the DAC machine that was tested in the second trial: the C-SAVE Green® CSG-64 from Seibu Giken DST. The company is currently developing higher-capacity machines, including the CSG104 and CSG304. These machines can utilize both electricity and heat. The new design is primarily aimed at achieving a significant reduction in energy consumption (kWh/kg CO2).
