The Bulgarian gas transmission system operator (TSO) Bulgartransgaz has joined the European Hydrogen Backbone (EHB) initiative, in which participate over 20 European gas TSOs, members of ENTSOG.
The initiative was announced in July 2020 and aims to create a hydrogen grid model consisting of an adapted existing gas infrastructure combined with investment in new hydrogen pipelines. EHB coordinates its activities with GIE (Gas Infrastructure Europe) and ENTSOG (European Network of Transmission System Operators for Gas).
The construction of hydrogen infrastructure in Europe is seen as an important part of the decisions needed to meet the EU’s climate and energy goals, including achieving carbon neutrality by 2050. The participation of Bulgartransgaz in EHB and the cooperation with other operators in the process of hydrogen infrastructure planning will contribute to the implementation of hydrogen technologies in Bulgaria and the transition to a low-carbon economy.
Currently, Bulgartransgaz is working on the development of three projects related to hydrogen. First, a project for infrastructure for transmission of hydrogen and low-carbon gaseous fuels in the East Maritsa region. Second, a project idea for infrastructure for transmission of pure hydrogen between the region of Sofia and the Bulgarian-Greek border near Kulata (a joint initiative with Greece’s TSO DESFA), allowing for future expansion to Romania and the East Maritsa region. Finally, a project idea for assessment and subsequent adaptation of the existing gas transmission infrastructure to work with up to 10 per cent hydrogen
These projects have the potential to become part of the future European hydrogen transmission corridors, including within the EHB initiative.
