Abstract:V diplomskem delu je predstavljeno teoretično ozadje shranjevanja energije in materiali, ki jih lahko uporabimo za shranjevanje energije. Vkjučena je primerjava osnovnih mehanizmov shranjevanja energije, s podanimi prednostmi in slabostmi vsakega mehanizma. Namen diplomskega dela je bil raziskati in opraviti pregled obstoječih in potencialnih materialov, s pomočjo katerih je možno termokemijsko shranjevanje energije. Osrednji del diplomskega dela vključuje podroben pregled materialov za termokemijsko shranjevanje energije. Materiali so razdeljeni na različne načine shranjevanja energije, kot so: shranjevanje s kemijsko reakcijo plin-plin, tekočina-plin, trdno-plin in kemijsko sorpcijsko shranjevanje energije. V nadaljevanju so predstavljeni najnovejši koncepti termokemijskega shanjevanja energije. Ti koncepti so: Izboljšani CaO peleti s dodatkom TiO2, sistem za shranjevanje energije na osnovi reakcije MnCl2 in NH3, reakcija na osnovi redoks para BaO2 in BaO, ter možnost uporabe SrCl2 za termokemijsko shranjevanje energije. Glavne prednosti termokemijskega shranjevanje energije v primerjavi z drugimi mehanizmi so: višja energijska gostota, najvišja efektivnost, možnost shranjevanja na daljši rok, pri ambientnih temperaturah in ta oblika shranjevanja energije omogoča transport le-te na večje razdalje. Stroški, ki jih prinaša razvoj, so visoki, postopek razvijanja je zahteven. V diplomskem delu je prikazana primerjava različnih materialov za termokemijsko shranjevanje energije. Kot praktični primer je podana ocena okvirnih stroškov uporabe za potrebe gospodinjstev v manjšem mestu. Možnost širše uporabe termokemijskega shranjevanja energije se kaže kot način za preprečevanje poškodb elektronskih naprav, ki jih povzroča toplota.
Keywords:termokemijsko shranjevanje energije, shranjevanje toplote, kemijska reakcija, faze procesa, materiali s kemijsko reakcijo.

Title:Thermochemical energy storage
Abstract:The bachelor thesis presents the theoretical background of energy storage in materials that can be used for energy storage. A comparison of the basic mechanisms for energy storage is made with the respective advantages and disadvantages of each mechanism. The aim of the bachelor thesis was to research and review existing and potential materials that can be used for thermochemical energy storage. The central part of the thesis includes a detailed review of materials for thermochemical energy storage. Here, the materials are divided into different types of energy storage such as: Storage by chemical reaction gas-gas, liquid-gas, solid-gas and chemical sorption energy storage. The latest concepts of thermochemical energy storage are presented below. These concepts are improved CaO pellets with additional TiO2, an energy storage system based on MnCl2 reactions in NH3, a redox reaction based on BaO2 in BaO, and another possibility of using SrCl2 for thermochemical energy storage. The main advantages of thermochemical energy storage over other mechanisms are: higher energy density, highest efficiency, possibility of long-term storage and, at ambient temperature, possibility of transport over long distances. The development costs are very high, the development process is demanding. The bachelor thesis presents a comparison of different materials for thermochemical energy storage. As a practical example, an estimate of the expected cost of using these materials for the needs of households in a small town is given. The possibility of wider application of thermochemical energy storage is cited as a way of avoiding damage to heat-generating electronic equipment.
Keywords:thermochemical energy storage, heat storage, chemical reaction, process phases, materials with chemical reaction.
