The European Hydrogen Backbone (EHB) initiative

The European Hydrogen Backbone (EHB) initiative consists of a group of thirty-three energy infrastructure operators, united through a shared vision of a climate-neutral Europe enabled by a thriving renewable and low-carbon hydrogen market.


The EHB initiative aims to accelerate Europe’s decarbonisation journey by defining the critical role of hydrogen infrastructure – based on existing and new pipelines – in enabling the development of a competitive, liquid, pan-European renewable and low-carbon hydrogen market.

The initiative seeks to foster market competition, security of supply, security of demand, and cross-border collaboration between European countries and their neighbours.


Participating companies include Amber Grid, Bulgartransgaz, Conexus, CREOS, DESFA, Elering, Enagás, Energinet, Eustream, FGSZ, FluxSwiss, Fluxys Belgium, Gas Connect Austria, GASCADE, Gasgrid Finland, Gassco, Gasunie, Gas Networks Ireland, GRTgaz, National Gas Transmission, NET4GAS, Nordion Energi, OGE, ONTRAS, Plinacro, Plinovodi, REN, Snam, TAG, Teréga, Transgaz, Transitgas AG and the TSO of UA.

The EHB initiative is governed through the Steering Committee, the chairwomen, and the secretariat. The Steering Committee consists of a representative of every EHB partner and is the main decision and governing body of the initiative. The chairwomen, who are also part of the Steering Committee, represent the initiative externally. The secretariat of the EHB initiative is run by Gas Infrastructure Europe, and is responsible for communication and coordination. EHB has grown as an initiative by a small amount of founding TSO partners to its current form in which near full coverage of the EU pipeline operator market is involved. Until 2024, Guidehouse has been involved as incubator, secretariat and research partner of the initiative, and has been responsible for communications.

Gas Infrastructure Europe

Gas Infrastructure Europe (GIE) is the association representing the interests of European gas infrastructure operators. GIE members are active in transmission, storage, and regasification via LNG terminals of natural, renewable and low-carbon gases, including biomethane and hydrogen. Gathering 70 industry entities from 25 European countries, GIE perfectly embodies the multiple transitional decarbonisation pathways of the EU regions. The association’s vision is that by 2050, the gas infrastructure will be the backbone of the new innovative energy system, allowing European citizens and industries to benefit from a secure, efficient, and sustainable energy supply.
