The EIA process will kick off on the Tornio to Porvoo leg to examine options to determine the final route for the pipeline following discussions with landowners and stakeholders, and detailed technical design.
Industrial companies are also being consulted on the route, through a market survey which has been open since 2023.
EIAs will also be conducted on the development in Northern Ostrobothnia, Western Finland, Southwestern Finland, and Southern Finland.
Once complete, Gasgrid will begin applying for permits to construct the network.
Earlier this year, Worley was appointed Owner’s Engineer for the network to provide front-end engineering and design until 2028.
The network is hoped to connect clean hydrogen production centres with industrial users, as well as linking into the 2,500km Nordic-Baltic Hydrogen Corridor (NBHC) that will link Finland, Estonia, Latvia, Lithuania, Poland, and Germany.
Speaking on a recent H2 View webinar, Gasgrid’s Project Manager and NBHC Project Director, Joonas Laitila, said widespread hydrogen infrastructure would support building a liquid market for the molecule in Europe.
