At Merschl Gartenbau, a tomato propagator near Vienna, CO₂ from biomass combustion is now being captured on site. The Dutch company Green Gas & Liquids has installed a full CO₂ capture system for the project. During a test on Friday 7 November, the system captured 1.8 tonnes of CO₂ per hour, even though the biomass boiler was not yet running at full capacity.
Besides capturing CO₂, the installation also recovers heat from the flue gases with an integrated heat-recovery system developed by Green Gas & Liquids. Because the propagator grows tomatoes year-round, the greenhouse will now be self-sufficient in biogenic CO₂ (link in Dutch).
An alternative approach to CO₂ capture
The heart of the system is the patented Galloxol Carbon Capture Technology. Managing Director Laleh Hosseini explains that this technology provides a safer, more environmentally friendly and more cost-effective alternative to traditional amine-based capture systems. The biodegradable solvent used in the Galloxol process has no vapour losses, so the system emits no harmful substances. That makes it especially well suited for greenhouses and other agricultural environments.
The successful CO₂ capture test took place 54 weeks after the contract for the Vienna project was signed. In that period the engineering, procurement, construction, installation and commissioning were all completed. Construction began in the spring. "We are incredibly proud of our team and our partners for delivering this project in such a short time. This milestone shows that CO₂ capture can be both sustainable and commercially viable, even at smaller industrial scales."
"This achievement represents an important step forward for Green Gas & Liquids and our partners in our mission to decarbonise industrial activity and promote circular CO₂ use. The successful test demonstrates how innovation and collaboration can generate real progress toward Europe's climate and energy goals."

Dutch projects
Green Gas & Liquids is a young Dutch company founded in 2022, building on the expertise and technology previously developed by Frames. Since 2019, several projects across Europe have been using the Galloxol technology. The first greenhouse-related project was completed in 2019 at DES in Sirjansland. Wijnen Square Crops in Egchel followed in 2021. A third complete CO₂ capture system was built in 2022 in Italy for FNXP LNG. That same year, another horticultural project was completed at Emsflower in Germany, this time focused on flue-gas reconditioning.
According to the current schedule, the CO₂ capture system at Merschl Gartenbau will be fully ready by the end of 2025 to supply CO₂ to eight hectares of tomatoes in the propagator's greenhouses near Vienna.
