In the paper highlights that hydrogen is critical importance for energy, due to its unique thermal properties. This gas high effective cooler for powerful turbogenerators at nuclear power plants, which ensures their increased reliability and energy efficiency, while requiring constant control of losses and uninterrupted supply using electrolysis plants. Showing that electrolysis plants are used to ensure continuous hydrogen supply, which, due to their high fire and explosion safety, require constant monitoring and strict control of operating parameters. The absence of such systems at most power generating facilities in Ukraine creates risks for the safe operation of equipment. In order to increase the reliability and safety of operation, the structure of an automated monitoring and control system is proposed, which includes a hydrogen leak detection subsystem and a valve position control subsystem, implemented on the basis of serial industrial modules with a digital interface, which provide flexible configuration of the QMS for different types of ES without interfering with their standard infrastructure. The architecture of the valve position control subsystem and hydrogen leak detection based on intelligent concentrators, wireless means of interaction and specialized sensors is proposed, taking into account explosion protection and sensitivity requirements in the operating conditions of electrolysis units at nuclear power plants. The feasibility of using highly sensitive capacitive MEMS hydrogen concentration sensors, which have low power consumption, high explosion protection and can be implemented in the form of integrated circuits, is substantiated, which will ensure increased reliability, explosion protection and contribute to the safe expansion of the use of hydrogen in other areas of carbonfree energy.
