H2Med Pipeline is a proposed hydrogen pipeline running from Spain to France.

Location

This pipeline has two separate segments. See below for details.

Project details

Bar-Mar Pipeline

Bar-Mar Pipeline is proposed to run offshore between Barcelona and Marseille, and will eventually be connected to the broader "Green Corridor" in the Iberian peninsula.

Background

BarMar Pipeline

The H2Med Pipeline is the third iteration of a proposed connection in between Eastern Spain and France. Originally envisioned as the Midi Catalonia project, it was shelved and revived in 2021 as a hydrogen-ready gas interconnection between Barcelona and Marseille (the Bar-Mar Pipeline).

However, as of January 2023 these plans have also seemingly been shelved in favor of a 100% dedicated subsea pipeline that was estimated to be 300-400 km long, and later as 400–450 km long. It is estimated that the subsea hydrogen link will cost around €2 billion, excluding the cost of linking the pipeline with connections on land, which could rise to around €3 billion depending on the underwater route the pipe takes.

The pipeline is expected to eventually connect to the Hydeal Espana Pipeline as part of the Green Corridor in the Iberian peninsula.

The Institute for Energy Economics and Financial Analysis released a report in December, 2022 highlighting the potential danger for a natural gas BarMar pipeline to become a stranded asset, as well as the gaps in technical capacity when it comes to effectively transporting hydrogen.

CelZa Pipeline

The CelZa Pipeline segment of H2Med began as the Hydrogen Interconnector Spain-Portugal, a natural gas pipeline proposal, but is now rebranded as a H2 pipeline as part of this project. As a result, the Hydrogen Interconnector Spain-Portugal is considered cancelled.
