  • Twelve European gas TSOs from eleven European countries have joined the EHB initiative
  • EHB group presents a vision for a 39,700km hydrogen pipeline infrastructure in 21 countries
  • Two-thirds of the network is based on repurposed natural gas pipelines
  • Lower investment cost per kilometre of pipeline compared to previous estimate


Today, Elering among  the European Hydrogen Backbone (EHB) initiative presents an updated version of its vision for a dedicated hydrogen transport infrastructure across Europe. The group proposes a hydrogen network of 39,700km by 2040, with further growth expected after 2040. This grid connects 21 European countries. The vision launched today follows the EHB report published in July 2020, which sparked a debate across Europe. That report described a network of 23,000km covering ten countries.

Two-third share repurposed pipelines
Some 69% of the proposed hydrogen network consists of repurposed existing natural gas grids. The remaining 31% newly built pipelines are needed to connect new off-takers and are located in countries with small gas grids today, yet with high expected future hydrogen demand and supply.

Lower investment costs per kilometre of pipeline
The almost 40,000 km envisaged 2040 backbone requires an estimated total investment of €43-81bn. The investment per kilometre of pipeline is lower compared to last year’s EHB report because the previous report only included cost estimates for pipelines with a diameter of 48 inch, while the present report takes into account that a large part of today’s natural gas infrastructure and of tomorrow’s hydrogen infrastructure consists of smaller pipelines. Smaller pipelines are cheaper to repurpose while leading to somewhat higher transport cost per kilometre. Transporting hydrogen over 1,000 km would on average cost €0.11-0.21 per kg of hydrogen, making the EHB a cost-effective option for long-distance hydrogen transportation.

Stable regulatory framework required
The hydrogen infrastructure maps for 2030, 2035 and 2040 published today reflect the vision of 23 European gas TSOs, based on their analysis of how infrastructure could evolve to meet decarbonisation targets. It is important to stress that the hydrogen transportation routes and timelines in the maps are not set in stone. The final Backbone design and timeline depend on market conditions for hydrogen and natural gas and the creation of a stable, supportive and adaptive regulatory framework.

“Europe needs to rapidly develop dedicated hydrogen pipeline infrastructure. This new EHB report shows a clear roadmap of how this could work”, says Prof. Ad van Wijk, author of the 2x40 GW Electrolyser Plan and advisor to Hydrogen Europe.

“We are glad that eleven new countries have joined the EHB initiative. Our new report shows that a truly pan-European hydrogen infrastructure largely based on repurposed existing gas infrastructure is possible”, says Daniel Muthmann, Coordinator of the EHB initiative and Head of corporate development, strategy, policy and communication at OGE.

According to Taavi Veskimägi, Chairman of the Management Board of Elering, hydrogen will play an important role in the realisation and storage of the potential of renewable energy in the future by ensuring the supply of energy to consumers at all times as well as the reliability of the integral European energy system. “Elering has taken the initiative to connect large open sea wind farms to the energy system when developing the Baltic Sea network in order to support achieving the climate objectives of Estonia and the European Union. Hydrogen can be used for transporting massive amounts of energy and for storing excessively produced electricity for the times when the wind is not blowing and the sun is not shining,” said Veskimägi.

Since an energy deficit is forecast in Central Europe in the future, with a surplus forecast in Northern Europe and around the Baltic Sea region, the planned hydrogen network could function as a transit corridor in Estonia in order to transport major amounts of renewable energy from Finland via Estonia to Central Europe. A hydrogen network through Estonia could realise the majority of the potential of local wind and solar energy by offering the market participants an alternative market for selling their energy. “Several industrial sectors in Central Europe and the Nordics have expressed an interest in using hydrogen in the future instead of the current fossil fuels, but in order for that to function, the security of supply of hydrogen must be ensured – the proposed pan-European network of gas system operators addresses this, as well as the capacity of high-volume hydrogen transport. Furthermore, the entire European Union would benefit from the realisation of the potential of the open Baltic Sea wind and the overland wind in the Nordics. The energy security of the EU would increase by using green hydrogen produced inside the European Union,” Taavi Veskimägi explained.
