European Hydrogen Backbone by Gas for Climate 2050

This paper, authored by eleven gas infrastructure companies aims to provide a contribution towards accelerating a large scale-up of hydrogen by enabling its transport from supply to demand across Europe.

System Level Description of Electrolyzers by IRENA

This report explores strategies and policies to drive innovation, cut costs for electrolysers and make green hydrogen a least-cost solution wherever needed. With larger production facilities, design standardization and insights from early adopters, the proposed strategies could cut costs by 40% in the short term and up to 80% in the long term, this study finds. The reports contain a clear presentation of the four types of electrolysers: Alkaline and polymer electrolyte membrane (PEM) – already at commercial stage ant Anion exchange membrane (AEM) and solid oxide - now at lab scale, promise a major step forward

Levelized Cost Of Hydrogen by Ørsted

The "Power-to-X" whitepaper by Ørstedin (2020) states that achieving cost-competitiveness for renewable hydrogen production hinges on five factors: • Capital expenditure • Efficiency of the electrolyser • Renewable power costs • Utilisation rates of the assets • Regulation ensuring a 'level playing field'
