20.500.12556/DKUM-43944 EKONOMSKA PRIMERJAVA PROIZVODNJE ELEKTRIČNE ENERGIJE S TRDNO OKSIDNIMI GORIVNIMI CELICAMI NA ZEMELJSKI PLIN ALI VODIK ECONOMIC COMPARISON OF ELECTRIC ENERGY PRODUCTION USING SOLID OXIDE FUEL CELLS ON NATURAL GAS OR HYDROGEN V diplomskem delu je izvedena ekonomska primerjava trdno oksidnih gorivnih celicah (SOFC) z uporabo goriva zemeljski plin ali čisti vodik. Za določitev energetske učinkovitosti gorivnih celic in ekonomsko primerjavo uporabe različnih goriv so bili uporabljeni podatki iz literature, strokovnih člankov in internetnih virov. Ker programska oprema simulacije delovanja gorivnih celic različnih vrst gorivnih celic ni bila na voljo, so bili energetski izkoristki SOFC povzeti iz znanstvene in strokovne literature. V diplomskem delu je izvedena tudi simulacija procesa parnega reforminga metana (steam methane reforming SMR) oziroma visoko kvalitetnega zemeljskega plina za proizvodnjo vodika. Vodik kot gorivo za SOFC se v tem primeru pridobiva iz zemeljskega plina s SMR postopkom. Za simulacijo procesa proizvodnje vodika iz zemeljskega plina je uporabljen programski paket Aspen Plus® V7.3.2.. Procesni pogoji in parametri za simulacijo so povzeti iz strokovne literature. Economic comparison of solid oxide fuel cells (SOFC) for two types of fuels ( natural gas or hydrogen) was carried out in this study. For the determination of energy efficiency and economic analysis information and data from scientific writings and technical literature were used. Because professional fuel cell simulation software for energy efficiency of different kinds of fuel cells was not available, energy efficiencies of SOFC were taken from scientific writings and technical literature. Process simulation of Steam Methane Reforming (SMR) for production of hydrogen is shown in this study. Hydrogen as fuel for SOFC is produced with SMR using natural gas instead of methane. Aspen Plus® V7.3.2. software was used for the process simulation. Process conditions and parameters used in simulation were taken from scientific writings and technical literature. gorivne celice električna energija simulacija energetska učinkovitost ekonomika fuel cells electric energy simulation energy efficiency economics true true false [D.
