Dutch Greenhouses Get CO₂ From Air, Not Fossil Fuels

Greenhouses across the Netherlands just solved two problems at once: growing better crops while ditching fossil fuels.

A new partnership between tech company Skytree and Lingezegen Energy is now capturing carbon dioxide straight from the atmosphere to feed greenhouse plants. The system will supply 10 greenhouses spanning 80 hectares with the CO₂ they need to maximize crop growth.

Plants need extra CO₂ to thrive and produce abundant, high-quality yields. For decades, greenhouse operators relied on industrial sources tied to fossil fuel production, but those supplies have become expensive, unreliable, and incompatible with climate targets.

Skytree's Stratus system changes the game by pulling CO₂ directly from the air we breathe. The technology uses a clever design that moves special carbon-capturing material between hot and cold chambers, heating only what's necessary rather than the entire steel structure.

This innovation slashes electricity use to just 0.9 megawatt-hours per tonne of CO₂ by tapping into low-grade waste heat. The system connects directly to Lingezegen Energy's renewable setup, which includes floating solar panels and thermal storage.

The modular design starts at 2.5 tonnes of CO₂ captured daily and scales up as needed. Advanced software monitors air conditions in real time, maintaining steady output even when temperatures swing from -35°C to 50°C.

The Ripple Effect

This partnership marks a turning point for sustainable farming. By decoupling food production from fossil fuels, Dutch growers can maintain their competitive edge while actively reducing their carbon footprint.

The technology isn't limited to greenhouses either. Companies producing sustainable fuels or carbonating beverages face similar CO₂ supply challenges and regulatory pressure to decarbonize.

After two years of lab validation, Skytree has transitioned from research trials to commercial manufacturing. Their standardized modules leverage economies of scale to reduce costs, while field upgradability means systems can integrate even better materials as the technology advances.

The system's modular architecture prevents full shutdowns during maintenance, ensuring farms never lose their critical CO₂ supply. For an industry where consistent crop conditions mean the difference between profit and loss, this reliability matters enormously.

The future of farming just got cleaner, and what works in Dutch greenhouses today could transform food production worldwide tomorrow.
