The Porthos project is being developed as an open-access transport and storage infrastructure which can be used by multiple parties to store CO₂. A so-called Expression of Interest process has been launched in order to obtain a clear picture of which companies are interested to become a customer, and when and how much CO₂ they are willing and able to supply. Companies can express their interest before 1 April 2019.
The Expression of Interest process is part of the preparations for the Porthos project. A decision about the realization of the Porthos project is expected to be taken in the course of 2020.
