ACCSION Project

Aalborg Portland is developing a large-scale carbon capture and storage project at its cement plant in Aalborg, Denmark to decarbonize one of Europe’s largest cement production facilities. The project aims to capture up to approximately 1.5 million tonnes of CO₂ per year from kiln exhaust gases, targeting near-complete elimination of process-related emissions and enabling the production of low-carbon and carbon-neutral cement products. The CCS facility is being developed in partnership with Air Liquide, which will supply cryogenic-based capture and purification technology capable of delivering high-purity, liquefied CO₂ streams suitable for permanent geological storage. The system is designed to capture up to roughly 95 percent of CO₂ from multiple kiln lines, integrating capture, conditioning, and liquefaction into a single industrial-scale installation. Captured CO₂ will be transported via newly developed onshore pipeline infrastructure to certified geological storage sites in Denmark, forming one of Europe’s first fully integrated inland CCS value chains spanning capture, transport, and permanent storage. The project also incorporates energy integration measures, including recovery of surplus heat from the capture process for use in Aalborg’s district heating network, improving overall system efficiency and local energy utilization. The project has secured major public funding support from the EU Innovation Fund, reflecting its strategic importance to European industrial decarbonization goals. Construction activities are planned to begin later this decade, with full-scale commercial operation targeted around 2030.
