The grand energy storage card game

The grand energy storage card game is a quiz game that makes the topic of electric energy storage fun for amateurs and experts alike! It should help you get to know the different storage technologies and their strengths and weaknesses. It is used as teaching material in the course Energy Storage I at Leibniz University Hannover.

Here is additional material, including the sources used for the information on the cards and further reading:

If you have suggestions for new cards or other wishes, we’d love to hear them! Send them to

Idea and implementation: Boris Bensmann and Richard Hanke-Rauschenbach. The card game was designed and produced together with the participants in Energy Storage 1 at Leibniz University Hannover in the winter semester 2015/2016. The cards are sporadically updated. Special thanks to (listed alphabetically):

  • Marcus Budt
  • Stephan Ferenz
  • Tanja Föhr
  • Mareike Henning
  • Anne-Kathrin Ittmann

Exclusion of liability: The research and preparation was done to the best of our knowledge and ability. However, we do not assume liability for the information (except for in cases of deliberate negligence). The individual sources used for each card can be found in the additional material mentioned above. Unknown data was supplemented with technology specific information and is marked with superscripts on the cards. The meaning of the superscripts is also explained in the additional materials above.

By the way: the research center Jülich – Institute for energy and climate research "Fundamentals of electrochemistry" (IEK-9) published a battery card game in April 2014.
