Energy Storage – Chances, Challenges and State of the Art
by Lukas Tomberg, Researcher, RWI Leibniz Institute for Economic Research in Essen
Selected by Gymnasium Neue Oberschule Braunschweig
The expansion of renewable energy is a source of increasingly volatile electricity supply. This volatility endangers grid stability, with higher risks of black- and brownouts.
Electricity storage could solve this problem by introducing the possibility of storing electricity in times when renewable energies like wind and sunshine are in abundance and by drawing down stored electricity when there is a shortage.
The analysis and promotion of innovation in the area of energy storage, as well as the development of other measures to address the increasingly volatile electricity supply, is a topic of applied economics and the focus of this YES-Challenge.
