The scope of the Roundtable is on the following four Ar-chetypes: 1. Transmission and distribution pipelines for local, regional, national, and international transport and storage facilities; 2. Marine storage and handling terminals in ports covering both existing as well as new terminals, 3. Shipping covering deep sea and short-distance maritime routes, 4. Inland distribution modes of transport including trucks, rail, barges, hubs and operational storage (such as bullets, tanks, containers, etc.).Figure 1: Potential H₂ supply corridors, European Commission, RePowerEU Communication Action Plan, May 2022.European Clean Hydrogen Alliance Learnbook on Hydrogen Supply corridors — 3 On 29 September 2022, the CEOs of the Roundtable gave the Sherpas the mandate to prepare a report on ‘H₂ supply corridors’, as outlined in European Commission’s RePowerEU Action Plan. REPowerEU outlined the need to accelerate development of hydrogen infrastructure for producing, importing, and transporting 20 million tonnes of hydrogen by 2030. The European Commission outlined three potential H₂ import corridors via ...
