Lighthouse Projects Showcase Climate-friendly Solutions for Neighbourhoods of Smart Cities

The new book "Innovations and challenges of the energy transition in smart city districts" presents six lighthouse projects that have advanced the energy transition in cities. It combines practical and scientific findings that should enable more climate-friendly districts in the future.


Economic Efficiency and Integration of Energy Storage Systems are Topics at an International Level

Powerful storage systems make it possible to use heat and electricity flexibly over time. The Energy Storage Technology Collaboration Program brings together these technology developments at an international level. Delegates from around 20 partner countries recently met in Berlin.



In the SmartQuart living lab, the energy transition is being driven forward in diversely structured neighbourhoods. Here, you can see the resource protection settlement in Bedburg.
