Storage Options for Renewable Energy

Abstract

In the recent years, the European energy policy has agreed on the increased integration of renewable energy sources in the energy system, and large efforts are being made to implement renewable energy. This tendency is not limited to the European market, but is a basic development in many regions. The energy policy is primarily based on climate change policy aims and demands, however further parameters are relevant in the portfolio of intentions for increasing the percentage of renewable energy sources, such as reduction of the import dependency and increasing the domestic value or price stability. To some extent, relatively high expansion rates in the implementation of energy systems based on renewable sources can be achieved, such as in Germany and China, for example.
