NOVELTY - The method involves producing electrical energy from power supplies, and transmitting the electrical energy in the form of direct current (DC) voltage over superconductive ground cables to a Roggmann loading station. The DC voltage is converted into chemical energy in the form of hydrogen and oxygen gas in a reversible fuel cell (RFC) system. Nitrogen is separated from hydrogen and oxygen gas to form high-purity gas. The high-purity gas is liquefied and passed through a multi-gas storage unit. DC voltage is produced from the liquefied gas in the RFC system.    USE - Reversible method for low-loss, time-spatial independent generation, transmission, distribution, storage and releasing of electrical energy by full utilization of non-periodic energy peaks and recuperated energies to be used in mobile and stationary transport, energy and construction applications utilized in terrestrial and extraterrestrial regions.    ADVANTAGE - The method enables generation, transmission, distribution, storage and releasing of electrical energy using smaller energy conversion systems. The method allows transmission of voltage of about 1-100 kilo volts and power of about 1 giga watts. The method enables unlimited energy transmission, avoids the need for additional implements for coolants, and simplifies a measuring, control and regulating (MSR) architecture, thus reducing software costs, and reducing weight, cost and space requirement of the energy conversion plant. The method allows utilization of unused non-periodic energy peaks. The method allows remote maintenance and controlledness of all sequences of functions. The method allows protection of the energy conversion plant from electromagnetic influences and influences of the weather, increases the life span of the energy conversion plant to 30 years, reduces primary energy requirement by 10 percentages, and reduces the maintenance cost. The method enables efficient recuperation of waste thermal energy into electrical energy, and allows long-term and short-term storage of thermal energy and chemical energy. The method allows increasing charging characteristics of all components from 0.1 to 100 percentages, controlling of all the components within one second, and increasing the fatigue strength of the components. The method allows operation of the components in low temperature regions. The method avoids the need for changing memory density during loading and unloading processes, and allows reducing intrinsic energy consumption in operating or idle conditions.
