Future work will put emphasis on the following fields:

• Continuation of the system monitoring (first and second generation prototype) in order to implement and test the developed control algorithms.

• Technical redesign of the storage modules.

• Production of a second generation prototype module.

• Development of stable modified sorption materials.

The newly developed second generation prototype needs to be extensively tested, analysed and evaluated under laboratory and practical conditions as input for the finalisation of the product development and identification of the most attractive market.
