Modularization and the Module Type Package (MTP) technology are proven concepts to ensure flexible plants and shorter time-to-market. Since the concepts are generic, they can potentially be applied to other domains. While the MTP approach has so far been used mainly in the specialty chemicals and pharmaceuticals industries, other sectors such as shipbuilding, logistics and hydrogen production show potential for adoption of this approach. In this article, such domains will be briefly examined, and the characteristics of the specific application are assigned to the requirements from modularization. The resulting analysis is transferred to the electrolyzer domain in hydrogen production in order to explain how the MTP technology can be applied there and how the hydrogen industry can benefit from the MTP approach. Furthermore, it motivates to transfer this approach to other industrial sectors that might not be considered in this contribution.
