Nordic-Baltic Hydrogen Corridor

The Member States currently undergo dynamic changes related to the energy transition and the decarbonisation of the European economy. Hydrogen is expected to be one of the key fuels in the EU's energy transition process. 

On14 December 2022 European gas transmission system operators from six countries - Gasgrid Finland (Finland), Elering (Estonia), Conexus Baltic Grid (Latvia), Amber Grid (Lithuania), GAZ-SYSTEM (Poland) and ONTRAS (Germany) - signed a cooperation agreement to develop cross-border hydrogen infrastructure from Finland through Estonia, Latvia, Lithuania and Poland to Germany to meet the REPowerUE 2030 targets.

The TSOs have initiated a project called the Nordic-Baltic Hydrogen Corridor to bolster the region’s energy security, reduce the dependency of imported fossil energy and play a prominent role in decarbonising societies and energy-intensive industries along its route. Furthermore, it has significant potential to contribute to the EU’s greenhouse gas emission reduction target by replacing today’s fossil-based production and fossil fuel consumption in industry, transport, power generation and heating.

Nordic-Baltic Hydrogen Corridor supports diversification of energy supplies, and accelerated the development of renewable energy technology enabling the achievement of the EU target of 10 million tonnes of domestic renewable hydrogen production by 2030. The corridor can transport green hydrogen produced in the Baltic Sea region to supply consumption points and industrial clusters along the its entire route, primarily the in central Europe.

The project endorses EU hydrogen strategy and REPowerEU Plan. In addition, the Nordic-Baltic Hydrogen Corridor will support several regional and EU climate targets, such as the EU Green Deal and Fit for 55 package.

PCI status  
In addition, the project has been recognised as contributing to the development of an integrated European hydrogen infrastructure under the TEN-E Regulation (Regulation (EU) 2022/869). 

On 28 November 2023, the European Commission published a list of projects that have been granted the status of common interest in the energy sector in the first PCI list (PCIs) for the transmission and storage of hydrogen, as well as the regasification of hydrogen or hydrogen derivatives. 

The Nordic-Baltic Hydrogen Corridor project was included in the PCI list as part of the 'Baltic Energy Market Interconnection Plan for Hydrogen' (BEMIP Hydrogen) and was granted the status of the Project of Common Interest in the European Union.


Project status 
Given the complexity of the initiative, all project partners take proactive steps towards its effective implementation. 

In December 2022, the project partners signed a cooperation agreement for the joint implementation of the project. In 2024, following a tender process run during 2023, GAZ-SYSTEM together with the partners signed an agreement with AFRY Management Consulting for a pre-feasibility study for the corridor. The purpose of the pre-feasibility study is to investigate the viability of a Nordic-Baltic Hydrogen Corridor and to define project parameters (such as the route, scope and capacity of the corridor), to prepare financial analysis, to develop a roadmap for project implementation and to define the main risk factors. The study will be completed by mid-2024. 

Next steps  
Based on the pre-feasibility study recommendations, decision will be taken on further actions leading to the implementation of the project.
