Ramboll analyses cluster collaboration on CO2 infrastructure in the Greater Copenhagen area
The cluster collaboration on carbon capture in the Danish capital can capture approx. 3 million tonnes of CO2 annually from energy facilities in the region. Ramboll analyses identified the key benefits of a cluster, including substantial reductions in the cost of transporting and storing CO2.
There is a potential to capture approximately 3 million tonnes of CO2 annually from the energy facilities in the cluster. Additionally, there is a potential for economies of scale by importing CO2 from nearby countries to drive economies of scale.
Ramboll prepared the following analyses:
- Scenario development and calculations on emissions, transport, and storage. Additionally, opportunities to use excess heat from CO2 compression and liquefaction were considered
- Requirements for carbon dioxide specifications and quality requirements
- International overview of emissions, transport chains, CCS policies, and import potential
- Climate impact of the required infrastructure
”The primary benefit of clusters is to drive down the cost of transport and storage of CO2. One of the major takeaways from our analyses was the demonstration of substantial economic benefits of cluster cooperation over individual initiatives with regards to removal of carbon dioxide,” says Project Manager at Ramboll Per Jørgensen.
Key identified benefits from a CO2 cluster
Through the technical analyses, Ramboll identified and quantified the key benefits from establishing a CO2 cluster.
- Reduction of duplicates in the CO2 value chain\n Establishing a shared value chain reduces the number of infrastructure facilities required for transporting CO2, such as ports and intermediate storage sites.
- Ensuring sufficient scale for pipeline infrastructure\n A joint investment into pipeline infrastructure future-proofs the system and drive lower unit cost – increasing significantly with scale, which opens the door for additional smaller point sources and CO2 import to Denmark. It also reduces the climate impact of the system and road congestion by reducing reliance on trucks for transport.
- Utilisation of larger ships for end-storage\n Combining multiple point sources allows for the utilisation of larger vessels for shipping CO2 to sequestration site, with significantly lower cost per tonne of CO2.
- Integration of multiple CO2 sources reduces variation across seasons\n By leveraging multiple CO2 point sources, ideally with asynchronous seasonal variation, the cluster will be able to drive down the unit cost, without significant increases in capacity.
- Integration with the modern energy system
With fewer, and larger, compression sites there is a potential for capturing and utilising excess heat in the district heating network
