Construction of a hydrogen pipeline between Bulgaria and Greece

The Bulgarian state company Bulgartransgaz is currently working on several projects to connect the hydrogen networks between Bulgaria and Greece, and this is necessary for energy security. This was stated by the Executive Director of Bulgartransgaz Vladimir Malinov at the Economic Forum in Sofia III.

Mr. Malinov added that he would be in Athens next week to continue the talks. According to him, connectivity must reach at least 5% by January 1, 2025, but more ambitious targets have been set to reach 10 to 15%.

A joint project to connect Sofia and Thessaloniki by a hydrogen pipeline is also envisaged.

“As of now, there will be a transition to hydrogen, which is not in competition but which is, on the contrary, complementary to gas”, said the head of Bulgartransgaz. He added that over time the ratio of green hydrogen to natural gas would increase.

As for the diversification of natural gas sources, the foundations were laid with the decision to make the first investment by a state enterprise outside the territory of Bulgaria with a 20% share of Bulgartransgaz in a gas terminal liquefied natural gas (LNG).

The LNG terminal, located in the Greek city of Alexandroupolis, will be ready for operation no later than January 1, 2024 and will offer Bulgaria an alternative source and a competitive price, Malinov believes.

The terminal will be connected to Greece’s gas transmission network by a 28 kilometer long gas pipeline. The gas will be able to reach Bulgaria, Serbia and North Macedonia via existing routes.

The other underground gas storage expansion project in Chiren, Bulgaria will serve not only Bulgaria but also other countries in the region. Development and investment in the LNG terminal will bring more stability to the market, Malinov also explained.
