The pilot study shows that the ammonia dissociation/synthesis reaction is inherently free of any potential side reaction problems, and also offers phase separation of products. The carrier of heat store is liquid. and is very interesting for long-term storage as it can be carried out at room temperature with no energy losses, Its theoretics energy storage density reachs 66.5kJ/mol, which outclasses sensible or latent heat storage. In comparison to other thermochemical energy storage, ATCES needs lower temperature in endothermic reaction(only 650℃), but It can produce over 550℃ high temperature stream in exothermic synthesiser. Furthermore, the heat store/recovery can change with adapt to the heat source/load automatically, and offers coninuous(24 h) production of heat, These advantages will see a rapid increase in the adoption of large-scale concentrating solar thermal power generation.
