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.
What are technical approaches to energy storage?
Which of these approaches are promising?
What is meant by the term “Power to X”?
What are the advantages as well as the disadvantages of this approach?
Which political measures could foster innovation in the area of energy storage?
What are the respective cost, chances and risks of these measures?
Which consequences regarding Germany’s energy transition would the market maturity of energy storage entail?
Which alternative measures could solve the problems of increasingly volatile electricity supply?

Lukas Tomberg first joined the Department of „Environment and Resources“ at the RWI – Leibniz Institute for Economic Research in October 2015 as an intern. He stayed at the RWI as a research assistant during his master’s program and is on the verge between finishing his master thesis and the beginning of his work as a researcher at the department of „Environment and Resources“.
His research interest is focused on the empirical analysis of topics concerning energy economics and the environment.
