Formed from an organic linker and a metal salt cluster, Metal Organic Frameworks (MOFs) are highly crystalline materials with a large surface area, pore size and pore volume. Some of these MOFs show a step-wise water adsorption behaviour. This would make them suitable for seasonal thermal heat storage through water adsorption, due to their high stability in a moist air environment and a relatively large adsorption capacity. This thesis is dedicated to modelling MIL-101(Cr), MIL-100(Fe), Aluminium fumarate, MOF-841(Zr), CAU-10(Al)-H, MIL-125(Ti)-NH2, MIL-160(Al) and CPO-27(Ni). The adsorption capacity was tested using two situations with a different set of temperatures. From these MOFs, three of the better performing MOFs were eventually tested, to measure the water adsorption energy density. With this data, the expected needed storage volume of the MOF was estimated, where the best MOF was chosen.
