A catalyst for decarbonising sectors such as industry and mobility, a solution for storing intermittent renewable energy and producing electricity, a source of reindustrialisation and non-offshorable job creation… Hydrogen is a real asset for Europe, both for reaching its targets on reducing greenhouse gas emissions, but also as a route to energy sovereignty. The use of renewable hydrogen can only be accelerated if a European low-carbon, competitive sector is put in place. With that in mind, Teréga was one of the co-founders of the European Hydrogen Backbone project, taking the form of a 53,000 km network linking 28 countries by 2040. Due to its strategic geographical position, Teréga has a particular contribution to make to the development of that section of the Backbone which is located in the south-west of Europe and France, through a number of infrastructure projects.
On 13 December 2022, the transport grid managers in France (Teréga and GRTgaz), Spain (Enagas) and Portugal (REN) signed a memorandum of understanding (MoU), thus committing themselves to working in a coordinated way to develop the H2Med project, the main pillar of the European Hydrogen Backbone. This is a green energy corridor linking Portugal, Spain and France to the European Union’s energy grid. H2Med covers the Portuguese, Spanish and French parts of the Backbone, along with the interconnections between Portugal and Spain (H2Med-CelZa project) and Spain and France (H2Med-BarMar project). The aim of that agreement is to make the network available from 2030. In addition, the projects that make up the H2Med corridor (H2Med-CelZa and H2Med-BarMar) are candidates for the list of priority Projects of Common Interest (PCIs).
Within the H2Med corridor, Teréga is promoter of the H2Med-BarMar project, with plans to establish an undersea hydrogen interconnection between Barcelona and Marseille (BarMar) by 2030, at an estimated cost of €2200m. It will have the capacity to transport up to 2 million tonnes of green and low-carbon hydrogen every year from 2030, equivalent to 10% of predicted European consumption by 2030 under the REPowerEU plan.
Led by Teréga, HySoW, Hydrogen South West Corridor of France, is a facilitator of the H2Med green energy corridor project. It is aimed at developing low-carbon and renewable hydrogen storage and transport infrastructures by 2030. This will allow the interconnection of major industrial and mobility hubs in Occitanie and Nouvelle-Aquitaine to flows of locally produced hydrogen, but also to those imported from Southern Europe, the Mediterranean and the Atlantic coast.
With its 600 kilometres of pipelines, the corridor will be able to transport 16 TWh/year of decarbonised hydrogen throughout the entire South-West. It will be structured around storage facilities located in Nouvelle-Aquitaine, with a capacity of 500 GWh GCV in 2020 and 1 TWh GCV in 2050. HySoW includes several objectives:
accelerating the ecological transition and decarbonisation of Occitanie
supporting the move to reindustrialise those territories;
strengthening security of supply for the entire European energy
It is one of the main pillars of the Mediterranean part of the future European Hydrogen Backbone.
