Because of their high energy density, chemical heat pumps are an interesting possibility for heat storage. With reversible chemical reactions the heat can be stored or released on demand by controlling the flow of the reactive fluid. If they prove to have satisfactory repeatability, the reversible reactions can also be used in a heat storage system for cogeneration systems. In this way it would be possible to even out the load of the cogeneration system: in a period of low heat demand the surplus heat is stored with the chemical reaction in the heat storage and during a peak load period it can be released with the reverse reaction. In this paper we discuss the operation of a chemical heat pump that uses the reaction between magnesium oxide and water. In this case the heat can be stored with a dehydration process at about 300400 o C and released with a hydration process at about 100200 o C. In order to test the potential of magnesium hydroxide as a reactive medium for heat pumps we performed reaction experiments over a range of operation pressures between 30 kPa and 203 kPa. For the experiment, a specially prepared reactant with good properties for repetitive operation was packed in a cylindrical reactor.

The cycle is repeated under various operating conditions that are characteristic for a heat-storage operation of a cogeneration system.
