AN OVERVIEW OF THE TECHNOLOGIES AND DEVICES FOR ENERGY STORAGE SYSTEMS
KOMUNALNA ENERGETIKA / POWER ENGINERING, 2
The growing need for energy on the one hand and the growing desire for integrating the units for production from renewable sources, on the other hand, inspired the development of energy storage systems. Electric energy production from renewable sources such as solar and wind, primarily depends on the current conditions and there is no possibility of the production in stock. Therefore, the abovementioned sources require the reserve in conventional sources or appropriate energy storage systems. An overview of the technologies and devices for energy storage systems that are most promising nowadays will be presented in this work.

ELECTRICAL ENERGY STORAGE AND CURRENT SITUATION OF ELECTRICAL ENERGY STORAGE IN GERMANY
KOMUNALNA ENERGETIKA / POWER ENGINERING, 23
New era of investment in renewables began in the last year. Due to technical needs for energy storage and network regulation, as well as government grants, Germany began developing energy storage systems for personal use and commercial purposes. Current battery storage systems based on lithium cells have efficiency of ~ 86%, with price per unit of installed power capacity ~1 €/W/Wh, and dropping. Year 2016 is expected to be a landmark year for electrical energy storage systems, as it is assumed that prices of electricity from solar power and energy storage system (with grant included) will reach the price of electricity from the electric grid. This paper presents current technical and economic state of energy storage systems for various needs.
