Case Study

Porthos CCUS




Port of Rotterdam, The Netherlands


Porthos needed to identify the corrosion risks of industrial CCUS associated with multiple impurities, this step is crucial to complete the first project in Europe to transport CO₂ from industry and store this in empty gas fields beneath the North Sea.


Porthos is developing a project to capture the CO₂ from industrial activities in the Port of Rotterdam. CO₂ will be transported through an offshore pipeline to a platform in the North Sea, approximately 20 Km off the coast and injected into empty gas fields, more than 3 Km beneath the North Sea. It is expected that, in its early years, the project will be able to store approximately 2.5 million tonnes of CO₂ per year. This project will be the first of its kind in the region.

OGC Energy Contribution

OGC Energy, in collaboration with PACE Flow Assurance Ltd., completed a full corrosion risk assessment to identify the effect of more than 25 impurities on all possible damage mechanisms for CO₂ transport. This assessment was the first of its kind, considering the CO₂ feed from different industrial sources in the Rotterdam area. OGC Energy's scope of work included:

1. Develop a methodology to evalute the risk of corrosion caused by the different impurities.

2. Identify the main risks of corrosion and stress cracking.

3. To provide recommendations regarding corrosion monitoring.
