TECHNOLOGIES OF CRYOGENIC STORAGE OF ELECTRICITY FROM RENEWABLE SOURCES
The peculiarities of storing electricity produced by traditional systems of its production and using renewable energy sources are considered, the state of the problem is discussed. Examples of industrial application of electricity storage systems using compressed and liquefied air are given. Liquid air storage systems have been shown to be the most efficient. A scheme for the accumulation of electricity and its production with the use of turbo-expander power generator units with the use of liquefied air is proposed. Taking into account the situation that has developed in Ukraine in connection with the spread of the COVID-19 virus, a scheme for obtaining liquid medical oxygen by the cryogenic method on low-tonnage transportable equipment is proposed.
