Second life for EV batteries: Audi and RWE build new type of energy storage system in Herdecke
  • Pilot project has storage capacity of around 4.5 megawatt hours
  • Trial operation started in November 2021
  • Innovative concept increases operating voltage and cuts costs

Audi and RWE are breaking new ground together to drive the energy revolution forward – RWE has brought an energy storage facility on stream in Herdecke, Germany, that uses used lithium-ion batteries from Audi electric cars. With the help of 60 battery systems, the new type of storage facility on the site of RWE’s pumped-storage power plant on Lake Hengstey will be able to temporarily store around 4.5 megawatt hours of electricity.
