Midi-Catalonia Pipeline

Midi-Catalonia Pipeline, also known as the MidCat Pipeline and Midi-Catalunya[1] (including its subset South Transit East Pyrenees (STEP))[2][3], was a proposed natural gas pipeline in Europe that is presumed cancelled.[4]

In the spring of 2022, the project was revived by the Spanish government which proposed that it could carry gas and, in the future, green hydrogen[5], as part of a plan to make Spain a hydrogen hub.[6]

STEP would have run from Hostalric to Figueres in Spain then to La Perthus and Barbaira, France.[8][9]

The MidCat Pipeline was initially pitched as part of the broader EU effort to reduce the bloc's dependence on Russian energy imports by shipping more gas from the Iberian peninsula to the rest of Europe. The project was cut into two sections. The first part is called the South Transit East Pyrenees, or STEP, and is meant to continue the existing abandoned line into France for 120 km, at a cost of about €440 million. France would cover two-thirds of that. The goal was for construction to be completed by 2022. The more expensive second half of MidCat would follow, including reinforcing about 800 km of the gas network in France. The full project aims to add about 7.5 billion cubic meters of cross-border capacity, approximately doubling the amount of gas that can flow between the two countries.[2]

In 2015, the project was awarded a €4.15 million grant from the EU's Connecting Europe Facility for pre-construction studies as well as the public consultation for the implementation of the first phase of the project on the French side.[12]

The pipeline was cancelled in January of 2019 after being blocked by French regulators following a determination that the pipeline was not financially viable.[13] The €3 billion project – which was prioritized for EU support by EU Climate Commissioner Miguel Arias Cañete in the EU's list of 'Projects of Common Interest' (PCI list), alongside 100 other gas projects – was last April found to be not financially viable under most scenarios, in an official cost-benefit study. Its cancellation throws into doubt the validity and legitimacy of the criteria used by the European Commission to prioritize similar gas projects on the PCI list.[4]

Project revival

In February 2022, amidst a European energy crisis and mounting tensions between Russia and the West, anonymous Spanish government sources were reported in the La Vanguardia newspaper as saying that NATO had designs on reviving the Midcat project, with alleged backing from Germany. This would potentially allow the transportation of mainly US LNG imports into existing Spanish and Portuguese LNG terminals and then onwards into the rest of Europe, thus boosting diversification away from Russian gas sources. No timeline for the plans was reported.[14]

In March 2022, the Spanish government began publicly promoting the revival of the MidCat pipeline, calling for EU public funding for the interconnector between Spain and France to be able to deliver gas from Spanish LNG import terminals into the heart of Europe. Spain's Minister for the Ecological Transition and the Demographic Challenge, Teresa Ribera, was critical of the reluctance being shown by French authorities to get behind the new MidCat concept.[15] In April 2022, the head of the regional government of Catalonia, Pere Aragonès, expressed support for MidCat's revival, saying that he was confident it could be built this decade to ship gas and potentially green hydrogen from Catalonia to France.[16]

In May 2022, in response to the European gas crisis and the EU's desire to wean off Russian oil and gas, the project was revived by the PSOE (Spanish Socialist Workers' Party), the PP (People's Party of Spain), and Ciudadanos to carry gas and green hydrogen.[5] The organizations sought to simplify the process of converting this into a Project of Common Interest, as part of a plan to make Spain a future hydrogen hub.[6][17]

As of the end of September 2022, Spain and France remained at loggerheads over the future of the project, with the Spanish government continuing to call for EU funds to back the construction of the pipeline. Diplomatic support for this has been provided by the German government, while French president Emmanuel Macron remained staunchly opposed. An unnamed former senior Spanish government official told the Financial Times that "MidCat seems a little like science fiction," and suggested that it would be more cost effective to send LNG by ship from Spain to Germany to be converted back into gas at new floating regasification plants that are being developed in Germany.[18]


In 2018, Friends of the Earth Europe and Fossil Free Europe released a report "MythCat: Debunking the Glory of the Midcat Pipeline Between France and Spain" saying, among other things, the the pipeline is at odds with the Paris Agreement. The report states that "oppositions to the construction of MidCat/STEP have sprung on both sides of the Pyrenees since 2011. Dozens of groups of concerned citizens, NGOs and members of the European Parliament are fighting against the project, contributing to public consultations, launching legal actions and putting pressure on decision makers at local, regional, national and European levels. Moreover, for some of these reasons, institutions like the French energy regulator are also opposing the project."[1]

350.org posted an article celebrating the cancellation of MidCat in 2019 calling it "a HUGE win for the local communities in Catalonia and France, who have been campaigning and protesting for years."[19]

A December 2020 report by Corporate Europe Observatory and other European environment groups warned that the European gas industry's rush to develop and seek public funding for new hydrogen infrastructure is being used as an excuse to revive previously cancelled gas infrastructure projects such as the MidCat pipeline.[20]
