We are committed to developing Carbon Capture and Storage (CCS) as the ultimate solution to achieve our Net Zero ambition by 2050. Some of these initiatives are supported by the European Union (EU) Innovation Fund.
What is Carbon Capture and Storage?
Carbon Capture and Storage (CCS) is a cutting-edge technology designed to capture carbon dioxide (CO₂) emissions produced by industrial processes before they enter the atmosphere. The captured CO₂ is transported to a suitable location, and securely stored. Potential storage methods include injection into underground geological formations, such as depleted oil and gas reservoirs or saline aquifers.
At Cementir Holding, we are committed to sustainability and innovation, and CCS plays a vital role in our journey towards achieving carbon neutrality by 2050.
Our CCS efforts complement innovative initiatives like FUTURECEM®, D-Carb®, and energy-efficient kiln technologies and all other measures to curb emissions, which are detailed on our Sustainability Strategy.
CCS – The ACCSION Project
ACCSION stands for Aalborg CCS using Infrastructure Onshore in North Jutland. It is Cementir first carbon capture industrial project and one of the first and largest full onshore carbon capture and storage value chains featuring inland geological storage in Denmark.
- Objective: avoidance of 1.5 million tons CO2 per year at the Aalborg site by 2029.
- Location: Aalborg, Denmark
- Technology: Cryogenic technology (Cryocap™) enabling high-purity CO₂ capture from cement grey and white kiln emissions
- Technology partner: Air Liquide
- Capex subsidy: € 220 million from the EU Innovation fund
The ACCSION project will be one of the first full onshore Carbon Capture and Storage (CCS) value chains in Europe. This innovative project will contribute to the achievement of the 2030 Danish climate targets, but also to create a lasting positive impact on the local community. It will cover the full CO2 value chain: capture, transport, liquefaction and onshore geological storage.
ACCSION will be jointly developed by Air Liquide and Cementir. Air Liquide, through its Cryocap™, proprietary technology using a cryogenic process, will capture, purify and liquefy approximately 95% of the CO2 emitted by Aalborg plant.
Thanks to this project, Cementir would be able to avoid 1.5 million tons of CO2 emissions per year at Aalborg cement plant starting from 2030.
Captured CO2 will be transported through a newly built pipeline infrastructure and permanently stored in onshore storage facilities.
The ACCSION project would be able to significantly increase the district heating to Aalborg households.
ACCSION being one of the selected EU-funded projects
ACCSION has been selected to receive support from the EU Innovation Fund with a grant of EUR 220 million. The EU Innovation Fund, one of the world’s largest funding programs for innovative low-carbon technologies, focuses on highly innovative technologies and flagship European projects enabling significant emission reductions.
Why this project is highly innovative:
- First full onshore CCS value chain in Europe: Captured CO2 will be transported to a CO2 reception hub by pipeline and then to a suitable onshore storage.
- Capture of CO2 for both grey and white cement
- Integration with Aalborg’s district heating system: The heat generated during the capture process will be recovered to supply the city's district heating system. This smart integration is unique and builds on an established collaboration with Aalborg's municipal utilities.
- Air Liquide Cryocap™ technology
What is Cryocap™ technology?
CryocapTM is an innovative solution developed by Air Liquide for carbon capture. It leverages advanced cryogenic technology to capture CO₂ emissions by liquefying the gas under high pressure.

FAQ: Understanding CCS
-
Q1: Why is CCS important for the cement industry?
A: Cement production is one of the most carbon-intensive industrial processes and is a hard-to-abate industrial process because the majority of CO2 emissions (60-65%) are produced during the manufacturing process due to the chemical conversion of limestone into calcium oxide, generating CO2 emissions as a by-product. These process emissions cannot be avoided. The role of CCS is crucial for decarbonization.
-
Q2: Is CCS safe?
A: Yes. Captured CO2 is stored in geological formations that have been thoroughly assessed for long-term stability and safety.
-
Q3: How does CCS align with Cementir sustainability goals?
A: CCS is a cornerstone of our strategy to achieve carbon neutrality by 2050, aligning with global climate targets and supporting a sustainable future for the construction sector.
-
Q4: What are the challenges of implementing CCS?
A: CCS requires substantial investments in infrastructure, energy, and technology. However, Cementir is addressing these challenges through innovation and collaboration with key stakeholders.
Additional decarbonization projects
Cementir has strategically and purposefully embarked on a dedicated journey to prepare for carbon capture projects. This initiative has included the launch of several pilot projects, providing the group with valuable experience and a deeper understanding of these innovative technologies.

Portland CC Project
Purpose
This project is part of the CO2 Vision partnership. The aim was to provide an initial techno-economic assessment of two carbon capture technologies: the amine scrubber technology (reactive absorption-stripping) and the Chart/Sustainable Energy Solutions Cryogenic Carbon Capture™ (CCC) technology applied to one kiln in the Aalborg Portland A/S cement plant. The analysis provides an estimation of component costs for the configurations under consideration using the features available in Aspen Plus®, along with electricity cost estimations for 2021 and 2022. Moreover, a suitable formulation for estimation of the cost of CO2 was presented.

| The total funds for the project were € 503,000 of which € 131,000 was funded by Cementir. This project is supported by the EU Regional Fund and the EU Social Fund, as well as the EU Just Transition Fund. | From 01-06-2022 to 31-08-2023. | Aalborg Portland, Aalborg University, Aalborg CSP. |
Results
Both the amine scrubber technology and the Chart Cryogenic Carbon Capture™ shown to be highly effective for capturing CO2 at high purity level and capture efficiency across gaseous and liquid states. The CCC technology, in particular, distinguished itself by offering a lower energy penalty, leading to reduced OpEx, and presenting lower initial CapEx compared to the amine scrubber technology.
During the project work some future research and development activities related to capture technologies were identified as including piping and networks between the capture process and transport and storage infrastructure. It was also suggested to look at integration of capture process with other domains e.g. district heating.
