Cement maker Aalborg Portland, Denmark’s largest emitter of carbon dioxide (CO₂), on Tuesday signed a contract with the country’s energy agency for 16.5 billion crowns ($2.55 billion) in carbon capture and storage (CCS) subsidies from 2030.
Denmark has one of the world’s most ambitious goals for reducing greenhouse gas emissions, aiming to slash emissions by 70 per cent from 1990 levels, and the CCS project is considered key to cutting CO₂ from hard-to-abate sectors such as cement.
“We can now take the decisive step toward realising a project that is not only significant in a Danish context but is also among the largest industrial CO₂ (carbon dioxide) capture projects in Europe,” Aalborg Portland CEO Soren Holm Christensen said in a statement.
Traditional cement production is responsible for around 8 per cent of global industry CO₂, generating huge emission volumes not only from the coal used to heat kilns but also during the process of converting limestone into clinker.
“Aalborg Portland will receive 875 crowns per captured tonne of CO2, corresponding to up to 1.1 billion crowns annually for 15 years, with the subsidies covering the capture, transport and storage of up to 1.25 million tonnes of CO2 each year,” it said.
The company added that it expects the project to account for more than half of the Danish CCS subsidy pool’s overall target of capturing 2.3 million tonnes of CO2 annually from 2029.
“Air Liquide (AIRP PA) will provide the capture technology for the project, while Harbour Energy (HBR L) will provide the transport infrastructure and storage,” Aalborg Portland said.
The International Energy Agency stated that CCS technology can play a vital role in achieving global climate goals, but critics are questioning its commercial viability and say it can prolong the use of fossil fuels.
