What Opportunities Do Stationary and Mobile Battery Storage Systems Offer for a Sustainable Energy Supply?

The smarter E Podcast Episode 161 | January 4, 2024 | Language: German

While fossil fuels are permanently available, solar and wind power often have to be stored temporarily so that they can be used when needed. Alongside hydrogen, batteries play a key role in storage and are increasingly being used in both mobile e-vehicles and stationary applications. But do battery storage systems have sufficient potential for the energy transition? What developments can still be expected? And what role will e-vehicles play as rolling energy storage systems for the future energy system? In this episode, we talk about this with Jan Figgener from RWTH Aachen University.


  • 02:21 The battery storage market is complex. What developments and trends can currently be observed in Germany?
  • 07:07 There is a lot of potential in electric vehicles. How can this dormant potential really be used to stabilise the grid?
  • 11:55 Will battery ageing end up being a problem, especially when implementing vehicle-to-X solutions? What can be done to counter this?
  • 18:56 What can we expect in the future? For example, what is currently being worked on or can we expect new battery technologies?

About Jan Figgener and RWTH Aachen

Jan Figgener holds a master's degree in industrial engineering from RWTH Aachen University after studying in Aachen and Istanbul. He is one of the operators of the Battery Charts and Mobility Charts websites and analyses the market development of battery storage and electric vehicles. Until the end of 2023, he headed the Grid Integration and Storage System Analysis department for three years with around 15 scientists and a focus on stationary storage systems, electric vehicles, charging infrastructure, sector coupling and battery ageing at the chair of Professor Dirk Uwe Sauer. He continues to be a guest researcher at this chair. He is also a Senior Battery Expert at ACCURE Battery Intelligence and works on battery condition estimates based on field data.

RWTH Aachen University is one of Germany's elite universities and is one of the most recognised technical universities in Europe. The Institute for Power Electronics and Electrical Drives (ISEA) was founded there in 1965 and has been under the direction of Prof Dr Rik W. De Doncker since 1996.
