Hydrogen, which is produced from renewable energies, is of fundamental importance in making industry climate-neutral. Despite technical advances and political support, there are still a number of challenges regarding the safety, reliability, efficiency and cost-effectiveness of green hydrogen production facilities. This article deals with the use of process analyser systems in hydrogen production and purification. In particular, the focus is on the implementation of process analytics in the plant, its significance for plant safety and hydrogen quality, and aspects of sample conditioning to ensure the functionality of process analysers in electrolysis plants, specifically using alkaline and proton exchange membrane (PEM) technologies. It emphasises the importance of powerful, fully-integrated process analyser systems. This guarantees stable processes, minimises downtime and ensures product quality. In turn, it contributes to an increasing market ramp-up of green hydrogen technologies.
