Carbon Capture Scotland to capture and reuse CO₂ from Iona Capital’s AD plants

news item image
Carbon Capture Scotland Limited (CCSL) has signed an agreement with Iona Capital (Iona), the UK low carbon investment fund manager, to capture and reuse green carbon dioxide from Iona’s biomethane plants located across the UK.
The captured carbon dioxide (CO₂) will be used by CCSL to create low-carbon and low-energy dry ice for use in the food, cold logistics and pharmaceutical industries.
The agreement between Iona and CCSL is an extension of their existing partnership at Iona’s Crofthead Anaerobic Digestion/biogas plant in Dumfries (south west Scotland), which is the first and only biomethane facility in Scotland to operate with carbon capture.
At their adjacent site to the Crofthead plant, CCSL takes the CO₂ from Crofthead to make dry ice for commercial use.
The two companies plan to extend their agreement to any future AD/biogas plants that Iona may develop in the UK, continental Europe and North America.
Alex Todhunter, investment manager at Iona Capital, said: “This partnership with CCSL offers the food, cold logistics and pharmaceutical industries a 'green' dry ice that will help towards their Net Zero and sustainability goals. The utilisation of CO₂ generated from farm waste and crops is yet another demonstration of how anaerobic digestion contributes to a sustainable low carbon future and the circular economy.”
Richard Nimmons, director of Carbon Capture Scotland Limited, said: “CCSL’s partnership with Iona will accelerate our business growth in our home market of Scotland and further afield. Importantly, it represents a scalable framework for clear, measurable carbon removal that brings us closer to our goal of removing 1million tons of CO₂ from the atmosphere per year.”
CO₂ is an essential compound used in the food, cold logistics and pharmaceutical industries and is most commonly produced as a by-product during ammonia production (circa 80% of the ammonia produced by industry is used in agriculture as fertiliser).
