The Athos project

The Athos project has been initiated for the construction of a basic capture- and transport infrastructure in the North Sea Canal area, to enable the usage or storage of CO2.


Industrial parties who are capturing their CO2 can express their interest in offering it to Athos. Since Athos is a non-discriminatory system, parties outside of the North Sea Canal area are welcome as well.
Project partner Tata Steel will capture production gases from one of its blast furnaces. Initially, carbon monoxide (CO) will be filtered out and processed into raw materials for the chemical industry. Subsequently, the remaining gas will be cleaned and the CO2 that remains will be offered for storage.


Existing underground pipelines can be used to transport the captured CO2. However, some of these will have to be renovated. The current research phase involves investigation of transport by ship. The liquid CO2 will be temporarily stored before transportation by underground pipeline to the permanent storage under the North Sea.


In the Netherlands, greenhouse horticulture already makes use of CO2. We expect that the use of CO2 in industrial processes will increase in the future, in the chemical and energy sector, for example, as well as in the production of new construction materials by means of CO2 mineralisation. A CCUS-infrastructure in the North Sea Canal can further stimulate this. 


An underground pipeline will transport the captured CO2 to a compressor station, which will compress the gas into the desired pressure. It will then be transported to a platform at sea, where it will be injected into empty aquifers, oil or gas fields under the North Sea.


A feasibility study for Athos has already been completed in 2019, with positive results. Various follow-up studies will now be carried to outline a more concrete project plan for a CCUS infrastructure. Currently Athos is still working with many uncertain variables and must now further investigate potential technologies, routes and scenarios, in order to establish a more profound business case. The network is expected to be operational in 2026.

CCUS in a broader context

Globally, efforts are being made to reduce greenhouse gases in order to combat climate change. These efforts are being further steered by the Paris Climate Accord, which comes into force this year. The Paris Accord, ratified by over 55 countries, is additionally supported by the new European Green Deal.

CO2isone of the most important greenhouse gases.. On the one hand, industries are working on making production processes more sustainable in order to ensure little to no CO2-emissions. On the other hand, it is possible to capture CO2 for reuse or storage. CCUS projects are being set out globally, for example in Canada, Australia, and Norway.

The Dutch Climate Agreement includes CCUS as one of the measures for the Dutch industry to reduce CO2 emissions. Athos is the second initiative in the Netherlands to build an infrastructure for the use and storage of CO2 in the North Sea, besides the Porthos project in Rotterdam. In the North Sea Canal area, Athos is part of a broader package of initiatives to drive sustainable development in the region.
