Abstract
This master’s thesis aims at creating novel and sustainable biomaterials for storing heat and releasing it on demand through thermochemical reactions. These materials consist of hygroscopic salt impregnated with porous carbon that can store and release energy via water sorption and desorption reactions. The salts act as the thermally active component that can be charged and discharged by a large amount of latent heat dehydration and hydration reactions, while porous carbon prevents the dissolution, swelling, agglomeration, and hydrothermal instability of the salts. Hydration enthalpy of 2599 J/g and 1936 J/g (Enthalpy accuracy of 1%) was recorded for activated carbon and biochar-based composites respectively. Composition characterization by SEM, BET and FTIR proved a successful impregnation of the salt in the carbon biomatrix.Description
