Driven by the need to reduce the LCOH by avoiding energy and cost intensive downstream mechanical compression processes highly pressurised low temperature water electrolysers are required. HYPRAEL’s goal is to develop and validate the next generation of AEL for highly pressurised H2 production (at least 80bar and preferable 100bar). Additionally, an immense increase in energy efficiency will be possible by raising the temperature to at least 120ºC. This results in transforming classic electrolysers into innovative devices for next generation. HYPRAEL will achieve these goals and move beyond the SoA by performing research from the design and the advanced assessment of electrocatalysts and polymers to the engineering and process intensification of an innovative cell design in 4 phases: 1) Materials development for pressurized electrolysis with elevated temperature; 2) Screening of materials for applicability in pressurized electrolysers – both phases will be performed at lab scale/single cell 10cm2, 1-30bar, 80-120ºC; 3) Upscaling of the most promising developed materials in Phase 1 and 2; 4) Upscaling of developed materials and integration into an advanced stack. The validation of the components scaled up in Phase 3 will be performed in the existing test bench of FHa designed in the frame of Elyntegration at 60bar, 120ºC, 6-15kW (pilot scale) whereas the demonstration at the target pressure above 80bar, at a temperature of minimum 120ºC and in a cell stack of at least 50kW capacity will be develop by GHS in a new test bench. In addition, the HYPRAEL concept strong focus on developing an energy efficiency high-pressure electrolyser while addressing the circularity principle of the objectives of the EU for a carbon neutral economy. We believe – 2 EU reference research centers in the hydrogen field such as FHa and FhG and 4 benchmark industrial partners, GHS, AGFA, VECO and SOLVAY – that HYPRAEL will bring the next generation of AEL for highly pressurised H2 production.

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.
