REALYZER REALyzer - Reliable and Efficient ALkaline Electrolyzers

Green Hydrogen Systems A/S

Hydrogen is envisioned to become a key energy carrier in the future 100% renewable energy system with predicted applications within transportation, grid stability, industry, re-electrification as well as a feedstock for conversion into other PtX products e.g., ammonia or liquid fuels. Realizing this transition relies on the availability of reliable and efficient electrolyzers at large scale, capable of producing green hydrogen at a lower price than fossil alternatives.

In the REALyzer project electrodes and diaphragms will be developed, upscaled to 430 kW stack and demonstrated at GreenLab Skive. The project aims to improve the efficiency, price and durability of the electrodes used in alkaline electrolysis by using new material combinations and newly discovered electrode processing solutions. REALyzer will make use of improvements to the currently used diaphragm systems leading to reduced ohmic resistance in the stacks and allowing for increasing operating temperature and higher current. A central objective is to employ scalable materials and manufacturing processes for alkaline electrolyzers and demonstrate improved performance of new electrode and diaphragm technology at large-scale in industrial environment.

In short, the REALyzer project will make improvements to the key components of the alkaline electrolyzer stack in order for green hydrogen to be able to compete with hydrogen from fossil sources and thereby pave the way for a society based on 100% renewable energy.
