Features of application of cryogenic thermoelectric generators in the systems of accumulation of the electric power using liquefied air (LAES) are considered. It is shown that the use of cryogenic thermoelectric generators as a heat exchanger-evaporator of the LAES scheme allows to increase the coefficient of electricity recovery by 10–15 % and reduce the equalized cost of electricity by almost 3 times — up to 0.03 $/kWh. The conclusion on expediency of application of similar schemes of accumulation of the electric power in the distributed power systems of the future is made. Bibl. 15, Fig. 3.
