Energy Storage – Chances, Challenges and State of the Art

 

This challenge was introduced by Lukas Tomberg, Researcher, RWI Leibniz Institute for Economic Research in Essen.

 

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?

    RWI – Leibniz-Institut für Wirtschaftsforschung Essen
    The RWI – Leibniz Institute for Economic Research is a leading center for scientific research and evidence-based policy advice in Germany and member of the Leibniz Association The economy matters for everybody.

    At RWI scientists analyze what happens in the economy, why it happens, and which consequences changes in economic conditions and policies have for the individual and the society as a whole. With this research, the institute supports politics, provides important bases for their decisions and evaluates political measures. For this purpose, the RWI conducts research in all areas – from the individual to the global economy – along four “competence areas”: “Labor Markets, Education, Population”, “Health Economics”, “Environment and Resources” and “Macroeconomics and Public Finance”.

    The RWI is partner of the YES!-Young Economic Summit in 2018.
