Abstract
V magisterskem delu obravnavamo sistem sočasne proizvodnje električne energije in toplote SPTE z batnim motorjem z notranjim zgorevanjem, ki kot gorivo izrablja ukapljen zemeljski plin. V ta namen smo naredili pregled tehnologij SPTE ter tehnologijo shranjevanja UZP. V nadaljevanju na podlagi urejenega diagrama določimo toplotno moč SPTE in volumen rezervoarja za ukapljen zemeljski plin. Na primeru dejanskega sistema daljinske oskrbe s toplote smo za SPTE sistem z motorjem z notranjim zgorevanjem in ukapljenim zemeljskim plinom izdelali študijo izvedljivosti. Izkaže se, da načrtovana prodajna cena toplote in referenčni stroški električne energije znotraj obratovalnega časa ne pokrivajo skupnih stroškov, ki nastajajo pri obratovanju postrojenja, zatorej je investicija ekonomsko neupravičena.

Title:Liquified natural gas powered combined heat and power system
Abstract:
This theses evaluates combined heat and power system powered by liquefied natural gas. To do so, one has to look at available CHP technologies and systems for LNG handling and storage. The aim of this work is to determine required heat power output of CHP and volume of LNG reservoir by analysing an arranged annual diagram of heat production. Hereinafter, a CHP plant and LNG reservoiar are put in space and evaluated by means of economics. It turns out, that sales price of heat and reference cost of electric energy, do not provide suffcient income for system to make profit.

Keywords:combined heat and power liquified natural gas levelised cost of electricity (LCOE) reference cost of electric energy (RCEE) internal combustion engine ICE
