Iron as a game changer
The documentary presented the work of the Metal Energy Hub alongside other innovative technologies, including ultra-light solar films from Heliatek and novel battery technologies from Batene. The focus was on one central question: How can technological innovations satisfy the enormous demand for electricity?
In the context of the energy transition
The NANO documentary emphasizes a crucial point: stable electricity prices and a sustainable energy supply – independent of fossil fuel imports – must be the goal. MEH's iron storage technology could become a key component in this, especially when converting existing infrastructure such as coal-fired power plants.
A look behind the scenes of the film crew's visit to the Lichtwiese campus can be found in the picture gallery. The documentary is now available in the 3sat media library:
