Porthos has taken a final investment decision to develop the first major CO2 transport and storage system in the Netherlands. In 2024, construction will begin in Rotterdam. Denys was selected for the engineering and construction of the onshore transport pipeline.

The onshore transport pipeline in which the CO2 is transported, is a steel pipeline with a diameter of 42" of almost 30 kilometres long. The pipeline will be mostly installed in the existing pipeline strip along the A15 via Botlek-Vondelingenplaat to the Maasvlakte. After the engineering period and the positive evaluation of the ecological assessment by the Council of State in August, the construction of the Porthos infrastructure is ready to start in 2024. Porthos’ and Denys’ teams are currently preparing construction works. The construction of the Porthos infrastructure has been scheduled for the coming 2 years. From 2026, CO2 will be stored under the North Sea.

The European Union has recognized Porthos as a “Project of Common Interest” and awarded the project a subsidy of € 102 million.

As a sustainable builder, Denys is proud to be able to take on this challenge with the Porthos team and to have earned the trust to help achieve this important step in the Dutch climate targets. The project will allow us to deploy our specific expertise and we hope to use that expertise in similar projects in other regions in the near future. In this project too, sustainability forms the backbone of both the design and the construction phase.

For the Netherlands it is clear: by 2050 the Netherlands must be climate neutral, and therefore greenhouse gas emissions must be drastically reduced. An important greenhouse gas is carbon dioxide (CO2). In the Dutch climate agreement has therefore expressly opted for the capture, transport and storage of CO2, known as CCS (Carbon Capture and Storage). A great example of this is Porthos, a project in which CO2 from industry in the Port of Rotterdam is transported and stored in empty gas fields under the North Sea.
