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 39,700 km by 2040, with further growth expected after 2040. This grid connects 21 European countries. The vision launched 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 for the European Hydrogen Backbone
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.
