Efficient or at least rational use of energy resources is a problem that is of great interest to the vast majority of people in modern society – from major scientists and politicians to journalists and schoolchildren who have little idea of the basic laws of physics (the knowledge of politicians in this area is also sometimes doubtful).

In the context of the digital transformation of the electric power industry, a key role in the maintenance of electrical equipment should be played by technical diagnostic systems based on data processing. To create such systems, it is necessary to study the methods and knowledge applied in existing products on the market that have been successfully implemented. The introduction of new data processing methods into existing systems can become an effective tool for managing the life cycle of electrical equipment.

A comparative analysis of the most widely used and developed electrochemical and hydrogen type storage devices, which are used in small and distributed power generation in the power range from 1 kW to 30 MW, has been performed. The accelerated development of these storage devices is due to the needs of households, transport, and energy supply in the absence or rejection of centralized energy supply. It is shown that hydrogen storage devices have the highest specific energy intensity three times higher than the energy intensity of liquid hydrocarbons and many times higher than the energy intensity of electrochemical storage devices. Sodium-sulfur batteries have the highest specific energy consumption of up to 500–700 Wh/kg compared with 200 kWh/kg for LIA lithium-ion batteries, have a longer life and service life, but due to lower replication, they are more expensive and less often used in transport. Lithium-ion batteries due to their sufficiently high energy consumption, relatively low cost up to $ 250 /kWh differs favorably from other types of batteries due to its high replicability and use in transport.

Over the past decades, digital technologies have greatly transformed people's daily lives. Smartphones with Internet access, navigation programs, online payment — all this has changed our understanding of the world around us, our understanding, convenience and comfort. However, digital technologies have brought about even greater changes in security in industrial plants and organizations. Automation, data collection and processing capabilities have allowed us to take process safety to a new level.
