Advanced alkaline electrolysis technology for pressurised H2 production with potential for near-zero energy loss

Project description

Advanced electrolysers tackle hydrogen compression challenges

Electrolysis is the bedrock of hydrogen production. Electrolysers operating at high pressures help reduce the energy and costs required for the mechanical hydrogen compression. The EU-funded HYPRAEL project plans to develop advanced alkaline electrolysers for hydrogen production at elevated pressures. Immense increases in energy efficiency are also expected by raising the temperature to at least 120 degrees Celsius. Researchers will test the ability of various materials to withstand high temperatures and pressures. The most suitable will be produced at a large scale and integrated in an electrolyser stack for validation. Ultimately, the project is expected to improve hydrogen electrolysis and facilitate the availability of hydrogen as an alternative fuel.

Objective

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 AREX. 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, AREX, AGFA, VECO and SYENSQO – that HYPRAEL will bring the next generation of AEL for highly pressurised H2 production.
