Gasgrid, the Finnish Gas TSO, has selected StreamTec Solutions AG as Gasgrid’s Owners Engineering partner to support development of hydrogen transmission infrastructure projects in the Baltic Sea.

This consists of 2 main projects, the Baltic Sea Hydrogen Collector (BHC) and the offshore section of the Nordic-Baltic Hydrogen Corridor (NBHC). 

The BHC is an ambitious initiative aimed at establishing an extensive offshore hydrogen pipeline network in the Baltic Sea region. Spearheaded by Gasgrid Finland, Gascade of Germany, and Denmark’s Copenhagen Infrastructure Partners, the project seeks to bolster energy security and advance the green transition across the Nordics and Europe.  

The BHC consists of a 1,250 km large diameter pipeline system which will be coated with 3LPE and concrete weight coating.  It is designed to link mainland Finland with Germany, with potential extensions to Sweden, Denmark, Poland and Estonia. This infrastructure will connect hydrogen production hubs located on the Åland, Gotland, and Bornholm islands, effectively harnessing the region’s substantial offshore wind energy potential. 

• November 2023 - The project is granted Project of Common Interest (PCI) status.
• November 2024 - STS is awarded the offshore owners engineer contract by Gasgrid.
• January 2025 -  BHC secures €15.3 million in funding from the EU’s Connecting Europe Facility (CEF).

StreamTec Solutions have experience in constructing ultra large offshore pipeline projects, as well as "hydrogen ready" pipelines and are actively involved in the DNV H2 JIP to develop an offshore hydrogen code.

Our contract award from Gasgrid as their owners engineer partner reinforces our position as industry leaders in developing offshore hydrogen systems.
