The project consists of a new hydrogen pipeline approximately 570 km long that will be constructed in parallel with the existing high-pressure gas pipeline. The purpose of the proposed infrastructure will be to connect hydrogen production units located in the Greek mainland with consumption points in Athens, Corinth and Thessaloniki industrial areas, where potential hydrogen consumers are expected to be located and subject to the relevant developments, with neighboring countries, namely Bulgaria, Italy and possibly North Macedonia in the future.

Total length570 km
Initial transport capacity80 GWh/d
CAPEX1000 mil. €
Exp. commissioning date2029

The project has already been selected in the 1st Projects of Common/Mutual Interest List of the European Commission and resubmitted in the 2nd List for assessment. In terms of funding, the project has secured €5.4 million from Connecting Europe Facility for the execution of studies to further mature the project.

H2DRIA is envisaged to be interconnected with the corresponding hydrogen transmission infrastructure proposed by Bulgartransgaz, the Bulgarian Transmission System Operator and is also part of the Southeastern Corridor of the European Hydrogen Backbone and more specifically of the South Eastern European Hydrogen Corridor Initiative (SEEHyC).

SEEHyC initiative is supported by 8 European TSOs (DESFA – Greece, Bulgartransgaz – Bulgaria, Transgaz – Romania, NET4GAS – Czech Republic, FGSZ – Hungary, EUSTREAM – Slovakia, OGE & naTran DE – Germany) and the corridor route will cover 2,854 km of repurposed gas and new hydrogen infrastructure, that will be able to initially transport 80 GWh/d from south to north.

DESFA’s participation to the initiative aims to strengthen Greece’s domestic hydrogen production capacity, as well as export activities to Central Europe. The establishment of hydrogen transmission infrastructure is the building block for the orderly operation and development of the internal European hydrogen market, as well as for imports. A well-designed and operational hydrogen transmission network fosters sustainable development and ensures equal access for both producers and consumers, guaranteeing the availability of hydrogen from diverse sources, thereby enhancing energy security, and promoting the optimal utilization of benefits stemming from direct and indirect emission reductions.

Given DESFA’s extensive experience in managing and developing networks at both national and regional levels, coupled with the initiatives it has undertaken in recent years, the company assumes a pivotal role in the advancement of infrastructure for the secure, efficient, and sustainable transmission of hydrogen.
