Technical challenges in scaling up alkaline water electrolysis

Green hydrogen produced from water electrolysis is widely seen as a key ingredient for a successful energy transition. At present, however, the technology is not yet widely used. This presentation will compare different water electrolysis technologies and discuss the technical challenges in scaling up. This will look not only at the electrolysis stack, but at the design of the whole plant. In addition, various options to achieve cost reduction will be discussed.

Technical Challenges in the Scale-Up of Alkaline Water Electrolysis

Green hydrogen, produced through water electrolysis, is generally seen as a crucial element for a successful energy transition. However the technology has not yet been applied on a large scale. This presentation will compare the different water electrolysis technologies and discuss the challenges in their scale up. It will not be restricted to only the electrolysis stack but will consider the design of an entire hydrogen plant. Opportunities to reduce costs will also be discussed.
