\nPorthos is not a commercial project by a single market player, but a publicly supported infrastructure with an open-access model. The project was created through intensive public-private partnership: a coalition of companies and governments with a single shared goal: CO\u2082 reduction and contributing to the achievement of climate targets. It is also striking that the customers for CO\u2082 capture were contracted well before the start of this CCS project. In the preliminary phase, every industrial party was able to join on equal terms. In international CCS projects, access is often limited to the original initiators.<\/p>\n
Whereas many CCS projects abroad have been set up around a single specific industrial installation, Porthos has been designed as an open infrastructure for an entire industrial cluster. The project \u2013 a collaboration between the Port of Rotterdam Authority, Gasunie and EBN \u2013 transports CO\u2082 from multiple industrial companies via a single shared network to empty gas fields under the North Sea, where the CO\u2082 is permanently stored.<\/p>\n
Collective infrastructure as an accelerator<\/strong> The fact that companies and organisations can use a collective system creates investment advantages. Porthos is therefore not only a technical project, but also a policy instrument: it lowers the threshold for broad industrial participation in CO\u2082 reduction. Especially for sectors such as refining, chemicals and hydrogen production \u2014 where full electrification is not yet feasible in the short term \u2014 CCS via Porthos offers a realistic route to rapidly reducing emissions.<\/p>\n Reuse of existing offshore infrastructure<\/strong> Permanent CO\u2082 storage<\/strong> Bridge technology during sustainability transition<\/strong> Strategic importance for industry and the economy<\/strong> More than technology<\/strong> One conclusion is already justified: Porthos is doing it \u2013 it is the first project of its kind in the EU to be implemented.

\nThis collective approach is a key difference from existing CCS initiatives. In the United Kingdom and the United States, for example, projects are often linked to individual factories or power stations, with customised solutions for each location. Porthos breaks with this model by building a single shared backbone to which companies can connect. The Aramis project, which is currently under development, will in future connect to the infrastructure that Porthos is now constructing.<\/p>\n![\"\"](\"https:\/\/www.porthosco2.nl\/wp-content\/uploads\/2025\/03\/3-maart-2025_Porthos_Platform-P18-A_HR-15-1-300x225.jpg\")
<\/p>\n
\nAnother important difference is the decision to reuse existing oil and gas infrastructure. Instead of building everything from scratch, CO\u2082 is stored in depleted gas fields under the North Sea. After gas extraction, these fields are at low pressure and are repressurised with CO\u2082.
\nThe platform and wells that have been used to extract natural gas for years have been converted for CO\u2082 injection. This choice reduces costs and speeds up implementation, but also presented unique technical challenges \u2014 for example, in the areas of pressure build-up, material behaviour and well integrity. These have been solved through a specific project design and extensive testing.<\/p>\n![\"\"](\"https:\/\/www.porthosco2.nl\/wp-content\/uploads\/2026\/01\/Opslag-ENG-1.jpg\")
<\/strong><\/p>\n
\nPorthos has deliberately opted for permanent CO\u2082 storage without reuse for additional fossil extraction, as is the case with Enhanced Oil Recovery (EOR). Whereas such applications do provide temporary storage but at the same time stimulate new oil and gas production, Porthos stores CO\u2082 in empty gas fields without commercial recovery. As a result, the climate benefits are structural and not linked to new fossil activities.<\/p>\n
\nAt the same time, the project is explicitly positioned as bridge technology: it helps the industry bridge the period until 2030 and 2040 while alternatives such as green hydrogen, electrification and circular raw materials are further scaled up. Storage under the seabed therefore has added value as long as other sustainability techniques are not yet sufficiently scalable and affordable, and fits within Dutch climate policy as a supplementary measure in a broader transition package.<\/p>\n
\nThe economic stakes are high. Without CCS, part of the energy-intensive industry threatens to leave the Netherlands, resulting in a loss of jobs, knowledge and strategic position. With Porthos, Rotterdam \u2013 and with it the Netherlands \u2013 will retain an attractive business climate for companies that want to become more sustainable and remain competitive.
\nUnlike some foreign CCS projects, which are primarily focused on reducing emissions within a single sector, Porthos combines climate goals with industrial policy: the project supports both CO\u2082 reduction and the preservation of a strong industrial base.<\/p>\n
\nThis makes Porthos more than just a technical storage project. It is a strategic choice that contributes to climate ambition, economic continuity and international competitiveness. We expect the project to be operational around September this year. The next fifteen years will show how powerful this combination is in practice.<\/p>\n
