In this work the HVOF coating process for producing nanocrystalline Al 2O 3- and Al 2O 3–Ni-coatings is described. Focus is on the process control, lamellae microstructure, lamellae interaction and their effect on mechanical coating properties, such as hardness, wear resistance and fracture toughness. 2.

The electrical energy is transformed into thermal energy by the heat sources. The thermal energy has to meet the demand from the downstream air-conditioning system. Thermal en-ergy storage systems can store thermal energy for a while. In other words the storages can delay the timing of thermal energy usage from electricity energy usage. Fig. 1 .
