Absorption systems Absorption heat pumps are essentially heat pumps that are driven by a source of heat, e.g. solar thermal energy, instead of electricity. In this report we refer to absorption systems as a form of TES, in which heat/cold can be generated in real time using solar absorption heat pumps and stored for later use. Absorption systems are based on the principle of a concentrated refrigerant solution (e.g. aqueous solutions of calcium chloride [CaCl2], lithium chloride [LiCl], lithium bromide [LiBr], sodium hydroxide [NaOH], potassium hydroxide [KOH] or ammonia [Lele, 2016]) absorbing water and releasing heat in the process. The heat released is the heat of sorption, which is the energy released when water vapour is sorbed into the volume of a liquid. The system is charged through the addition of heat, causing water molecules to desorb from the refrigerant solution. This forms two products: water vapour and a more concentrated solution of refrigerant. These products can then be separated and stored until heat is required, when they can be combined again. Figure 33 shows a schematic of an absorption system with a solar thermal heat source, an absorption heat pump, and separated concentrated refrigerant and water tanks. Absorption systems are a promising storage option because energy storage densities greatly exceed the storage density provided by water as a sensible storage technology. This is primarily because the absorption cycle is more suitable for low-grade heat utilisation, making the systems potentially useful for buildings and certain industrial applications.
