WS1 – Large-scale electrolysis

Workstream 1 focuses on the deployment and integration of large-scale electrolysers with capacities between 50 and 500 MW. These facilities form the backbone of hydrogen production via electrolysis in Europe. The aim is to overcome significant initial market failures for hydrogen production by the joint approach along the entire value chain. By pooling expertise from 16 companies across five EU Member States, WS1 will significantly advance Europe’s transition toward sustainable hydrogen production. The activities considered in WS1 are expected to contribute towards the following overarching objectives: 

  • Install and operate multi-hundred-MW electrolysers to accelerate renewable hydrogen production
  • Enable systemic integration of electrolysers into electricity grids and hydrogen transport networks 
  • Contribute directly to the EU goal of 40 GW electrolysis capacity by 2030
  • Drive economies of scale and reduce costs through coordinated development and best-practice exchange 
  • Establish standards and recommendations for safety, performance, and interoperability of large-scale electrolysers

Under WS1 the following projects are taking place:
