The Bosnia and Herzegovina–Croatia South Interconnection Gas Pipeline is a proposed natural gas and hydrogen pipeline in Croatia and Bosnia and Herzegovina.

Location

The planned pipeline route runs from Split, Croatia through Zagvozd, Croatia to Travnik, Bosnia and Herzegovina, with a 46-km spur to Mostar, Bosnia and Herzegovina. The exact route can be seen on p.2 of BH-Gas's October 2019 presentation to the CESEC Gas Plenary Meeting.

Background

The feasibility study for the Bosnia and Herzegovina–Croatia South Interconnection Gas Pipeline was completed by the Infrastructure Project Facility 2 in November 2013.

In July 2019 the project was approved by the Directorate-General for European Neighbourhood Policy and Enlargement Negotiations. Mott MacDonald began design work in November 2019 and hopes to complete it by Q3 2020. The pipeline's route is partially redundant with the proposed Ionian Adriatic Gas Pipeline. The pipeline will provide an alternative gas source for Bosnia and Herzegovina, which is almost entirely dependent on Russia for gas.

The project is receibing financing from the European Bank for Reconstruction and Development in the form of a €87 million loan and a €400,000 grant from Western Balkans Investment Framework.

The pipeline is also touted as being H2 ready, and will be able to carry a blend of hydrogen and natural gas through it.

In February 2020 Bosnia's gas firm BH-Gas selected a contractor to undertake a feasibility study and an environmental impact assessment for the proposed pipeline to Croatia. A consortium led by Croatia's Dvocut-Ecro was awarded a contract worth US$500,000 for this work, which is being covered by a grant from the United States Agency for International Development with the European Bank for Reconstruction and Development overseeing how the grant is spent.

The European Network of Transmission System Operators for Gas codes for the project are TRA-N-851 (Bosnia and Herzegovina) and TRA-A-302 (Croatia).

According to Energy Community, as of August 12, 2021, the permitting process is 30 percent complete for the Bosnia and Herzegovina section and 80 percent complete for the Croatia section.

However, a report on Jul 7th, 2022 noted that the central government of Bosnia and Herzegovina "failed to reach a consensus that would allow it to negotiate with Croatia on a preliminary draft of a planned agreement to build the South Interconnection of BiH and Croatia."

In February 2023, Croatia announced that it would participate in the €100 million project, which would connect its gas network to Krk FSRU and the gas network of Bosnia and Herzegovina.

This pipeline project was originally proposed as a solely fossil gas project, and was included in the ENTSOG TYNDP 2020 and 2022 as such. In the 2024 TYNDP it was registered as a hydrogen project. Despite it being listed as a Hydrogen project the pipeline will tranport fossil gas 'in the first years...if H2 market is not developed until commissioning date". For this reason the project has been listed as a fossil gas and hydrogen project.
