100 MW Green hydrogen production in a replicable and scalable industrial hosting environment

The objective of GreenHyScale is to pave the way for large scale deployment of electrolysis both onshore and offshore, in line with the EU hydrogen strategy and offshore renewable energy strategy.GreenHyScale will develop a novel multi-MW alkaline electrolyser platform with factory assembled and pre-tested modules, allowing rapid onsite installation capable of reaching a CAPEX below 400 EUR/kW by the end of the 5-year project.

A 6 MW module fitting into a 40-foot container will be demonstrated as the first step in the project, and lead to a minimum 100 MW electrolysis plant located in the ideal hosting environment of GreenLab Skive: a symbiotic, industrial Power-to-X platform capable of replicating across Europe with associated green growth and job creation benefits.The minimum 100 MW electrolysis plant will generate green hydrogen for 2-years from 80 MW directly connected renewables in combination with certified green electricity from a TSO grid connection.

GreenLab Skive distributes green electricity from both sources through its unique SymbiosisNet which optimises and exchanges energy in all forms (heat, gas, water, heat) between the industrial park entities and external suppliers and offtakers. The setup enables the electrolysis plant to reach an overall energy efficiency above 90%.

The GreenHyScale electrolysis plant will become the world's largest electrolyser system qualified as a TSO balancing services provider, thereby reducing the cost of hydrogen to below 2.85 EUR/kg for an electricity cost of 40 EUR/MWh.Besides, because of the inevitable link between offshore wind and electrolysis, an upgraded high-pressure 7.5 MW electrolysis module suited for offshore applications will be developed.GreenHyScale will form new European green value chains that support the paradigm shift to hydrogen economy and transition to green energy by overcoming both technical upscaling and commercial barriers.

GreenHyScale will pave the way towards GW-scale electrolyser plants.
