Air Liquide CCS cement project in Denmark gets subsidy of 117 euros per tonne of CO2 captured

Danish cement producer Aalborg Portland signed a deal with the Danish Energy Agency for a carbon capture subsidy of around 117 euros per tonne of CO2 captured. The subsidy supports the Accsion CCS project, a partnership with Air Liquide, targeting up to 1.25 million tonnes of CO2 annually from 2030. The subsidy is worth up to 146 million euros per year over 15 years, indexed to inflation. The project uses Air Liquide's Cryocap cryogenic technology to capture high-purity CO2 from cement kiln emissions. It is expected to deliver nearly half of Denmark's national target of capturing 2.3 million tonnes of CO2 per year. The project is positioned as one of the first full onshore CCS value chains in Europe. A separate analysis from the Mineral Products Association found that carbon capture could cut cement sector emissions by 75% by 2035. The trade body warned that delays to CCS projects risk constraining housing, transport, and energy infrastructure delivery in the UK.

117 euros per tonne is a pretty clear price signal for cement CCS. Interested to see if that covers the full cost or if Aalborg still needs carbon credit revenue on top.

Good point. The article says indexed to inflation, but doesn't mention if the subsidy covers transport and storage or just capture. Those costs add up fast.

2030 start date is ambitious for a first of its kind onshore CCS chain in Europe. Would like to see the permitting timeline and how they plan to handle the CO2 transport.

The Danish Energy Agency deal gives it a solid regulatory anchor. But the 15 year subsidy term means the project needs to be cash flow positive without it after 2045. That's a long horizon for cement demand.

Cement is hard to decarbonize any other way, so CCS makes sense here. But 117 euros per tonne is still expensive. Wonder how that compares to the cost of alternative cements or clinker substitution.
