Within the EPSO-G Group, we aim to develop a transmission network for a new energy carrier – hydrogen – in Lithuania and connect it with neighbouring EU countries. The Nordic-Baltic Hydrogen Corridor project has been recognised as an EU Project of Common Interest (PCI). Through this project, we aim to establish a hydrogen corridor for transporting green hydrogen from Finland and the Baltic States to the Central and North-Western European markets and create conditions for the development of the renewable hydrogen market in the Baltic Sea region. We also aim to accelerate the green transition by developing hydrogen infrastructure and creating conditions for a competitive low-carbon hydrogen market across Europe. The development of Lithuania’s hydrogen network is essential for enabling hydrogen transit through the Nordic-Baltic corridor and the use of these resources to meet domestic needs. The network is expected to become operational after 2030.
