Abstract

Due to the very intensive development of renewable energy sources, producing electricity in irregular and unpredictable way, storage plays an increasingly important role in the current energy system. Currently used systems for storing electricity on a large scale include only pumped storage and compressed air energy storage. The paper presents energy analysis of three underwater energy storage systems based on compressed air without recuperation, and with recuperation and adiabatic. Balance calculations for selected configuration of the system was performed. The efficiency of storage of electricity was calculated using four different definitions
