摘要： This invention relates generally a method of thermal energy storage or heat pump using reversible chemical reactions. Within a reversible cycle, inorganic oxoacid compounds and/or their salts ,oxoacids of either nitrogen, sulfur or phosphorus, or its corresponding salt, are hydrolysed and condensed or polymerized in order to release and capture heat. It is accordingly a first aspect of the present invention to provide the use of inorganic esters in a method of thermal energy storage, in particular using inorganic phosphoric acids and/or their salts.
The invention further provides a method to store thermal energy, said method comprising polymerization of the inorganic oxoacids using an external heat source. In a further aspect the invention provides a method to release thermal energy from said heat storage comprising an exothermic hydrolysation step of the inorganic oxoacids and/or its salt. If no cooling takes place between polymerization and the hydrolyzing step, one can create a heat pump. Such a heat pump might be extremely useful to upgrade waste heat from industry to a higher more valuable level.
Using the methods and components of the present invention it is possible to store thermal energy at ambient circumstances in a transportable medium. As a consequence it allows converting a continuous heat generation process into a discontinuous and even dislocated consumption.
