Skytree, a Netherlands-based cleantech firm, is deploying a direct air capture (DAC) system at the site of Dutch energy company Lingezegen Energy. The system will capture 900 tonnes of CO2 per year starting in 2025, with plans to scale to 7,200 tonnes per year by 2027. The captured CO2 will be supplied to 10 greenhouses across 80 hectares for crop enrichment, replacing fossil fuel-derived CO2. The technology uses a modular design that moves sorbent material between cold and hot chambers, heating only the CO2-capturing material rather than the entire unit. Skytree claims this reduces electricity consumption to as low as 0.9 MWh per tonne of CO2 captured. The project aims to build a decentralized CO2 supply chain for growers while reducing their carbon footprint. DAC costs remain high, estimated between $500 and $1,900 per tonne of CO2 by the IEA. However, the project addresses a specific need: Dutch greenhouse operators face a shortage of sustainable CO2 as the sector decarbonizes. A recent CE Delft study warned that sustainable CO2 supplies will remain scarce in both the short and long term.
