Brief Project Description

The project comprises the construction of a High-Pressure Hydrogen pipeline that starts at Agioi Theodoroi in Corinth and ends at the border between Greece and Bulgaria.

The pipeline route is designed to run parallel to the already existing mainline of the National Natural Gas Transmission System (NNGTS). 

The purpose of this infrastructure is to connect hydrogen production units located in the Greek mainland with consumption points in Athens, Corinth and Thessaloniki industrialareas, 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.
