Fifth generation fruit grower Claus Haak with his farm in the wonderful Altes Land region near Hamburg has decided to generate as much of the energy he needs for cultivation through to the sale of his apples from renewable sources using a photovoltaic system and also to buffer this electricity in an energy storage system so it can be used on overcast days or at night.

The system utilizes a Gildemeister CellCube FB 10-100. The CellCube energy storage system is based on vanadium redox flow technology which allows for stable power supply. The Haak family has taken on a pioneering role in resource-saving energy generation and harbors the vision – one that will hopefully soon come true – of running the farm to 100% on the energy they produce themselves completely independently of the public electricity grid.
