Optimization strategies of PEM electrolyser as part of solar PV system

Solar and wind power have intermittent nature. In order to guarantee continuous power supply, they need to be accompanied with energy storage systems or bridges between different energy sectors. Hydrogen is a potential candidate for both applications (an energy storage system and bridging technology). Hence, it is interesting to study the practical dynamic properties and limitations of electrolysers in the viewpoint of renewable energy production. This paper studies optimization strategies of a proton exchange membrane (PEM) electrolyser together with a solar photovoltaic (PV) system.
