Comparative Analysis of Energy Storage Methods for Energy Systems and Complexes

The daily non-uniform power demand is a serious problem in industry. In addition, recent decades show trend for the transition to renewable sources, but their output depends upon weather and conditions. These factors determine urgency of energy accumulation technology research development. presence wide variety storage mechanisms leads need classification comparison as well consideration possible options application modern units. This paper presents comparative analysis methods systems complexes. Recommendations are made on choice technologies change cost supplied at plants by integrating various estimated implementation considered. It revealed that large-scale production industry, most productive complexes following: pumped hydroelectric systems, thermal thermochemical accumulations, hydrogen systems. have best technical economic characteristics. resulting recommendations allow assessment effect achieved integration stage designing new
