Research relevance This article presents a mathematical solution to the issue of a comparative analysis of various types of energy storage devices and determining the most efficient type of energy storage device for use on an industrial scale. The subject of the study in the article is the most important parameters of seven types of energy storages, the use of which is spreading in the world. The purpose of the work is to obtain an answer to the following question: which of the ubiquitous different types of energy storages is most likely to be the most efficient for the future industrial energy supply? The following tasks are solved in the article: 1) generalization of the collected data; 2) analysis (evaluation) of data using mathematical methods of data analysis. The following research methods are used: comparison, abstraction, axiomatic, analysis, synthesis, formalization and induction. The following results were obtained: among the analyzed energy storages, the best result was shown by a mechanical potential (gravitational) energy storage. Conclusions: If it is planned to use energy storages on an industrial scale in various fields, it should be recognized as expedient to give preference to gravitational devices.
