Possibilities and prospects of accumulation of the electric power generated on objects of renewable energy sources - solar and wind power plants, with use of cryogenic liquids are considered. A comparison of the three most common ways of accumulating electricity: using lithium-ion batteries, hydrogen, liquid air. According to the proposed technology, the efficiency of recovery of electricity from liquid air is from 54 to 70%. The developed technology is based on cryogenic and thermal accumulation and has a high accumulation coefficient. It is shown that energy storage in cryogenic storage devices is the cheapest today. The proposed technology can also be used to generate electricity from liquefied natural gas using standard equipment developed by industry. The technological scheme of the cryoaccumulating station is offered. Bibl. 10, Fig. 1, Table 1.
