Abstract:Vodik predstavlja enega ključnih energijskih nosilcev prihodnjih nizkoogljičnih energetskih sistemov ter pomembno rešitev za razogljičenje sektorjev, kjer neposredna elektrifikacija ni tehnično ali ekonomsko izvedljiva. Med najpomembnejše izzive pri vzpostavitvi vodikovega gospodarstva sodi učinkovita distribucija vodika, saj različni načini transporta pomembno vplivajo na stroške oskrbe in razvoj potrebne infrastrukture. Namen magistrskega dela je razviti tehnoekonomski model za primerjalno vrednotenje alternativ distribucije vodika za cestni promet v Republiki Sloveniji ter določiti pogoje, pri katerih posamezna transportna rešitev predstavlja ekonomsko najugodnejšo možnost. Raziskava je obravnavala dve najpogosteje uporabljeni alternativi transporta vodika: transport komprimiranega vodika s tovornjaki in transport po cevovodih. Analiza je vključevala primerjavo scenarijev centralizirane proizvodnje vodika v Ljubljani in Krškem ter vrednotenje vpliva lokacije proizvodnje na stroške oskrbe predvidenega omrežja vodikovih polnilnic v Sloveniji. Pri transportu s tovornjaki je analiziran vpliv različnih tlakov komprimiranja vodika (350 bar in 540 bar), pri cevovodnem transportu pa vpliv različnih premerov cevovodov na investicijske in obratovalne stroške sistema. Metodološki pristop je temeljil na pregledu znanstvene literature, razvoju matematičnih modelov za izračun investicijskih in obratovalnih stroškov ter izvedbi tehnoekonomske analize obravnavanih scenarijev. Za primerjavo alternativ smo uporabili kazalnik leveliziranih stroškov transporta vodika (LCOHT), izvedli pa smo tudi občutljivostno analizo za določitev vpliva ključnih tehničnih in ekonomskih parametrov na končne stroške distribucije. Rezultati kažejo, da je transport vodika iz Ljubljane po cevovodu s premerom 100 milimetrov ekonomsko najugodnejša med obravnavanimi rešitvami. Optimalna lokacija proizvodnje vodika je srednja Slovenija (v obravnavanem primeru Ljubljana) zaradi lažje razporeditve cevovodnega sistema oziroma poti tovornjakov in dostopnosti do drugih lokacij. Rezultati tudi kažejo, da je v primeru izbire transporta vodika s tovornjaki komprimiranje vodika na tlak 350 barov cenejše kot komprimiranje na tlak 540 barov, ne glede na lokacijo. Občutljivostna analiza je pokazala, da je v obravnavanem razponu sprememb izbranih parametrov cevovodni transport ostal stroškovno ugodnejši. Prav tako se je ugotovilo, da je v primeru transporta vodika s tovornjaki cena goriva najpomembnejši dejavnik, ki vpliva na končne stroške transporta vodika. V primeru cevovoda pa je najpomembnejši dejavnik cena materiala cevi.

Title:Techno-Economic Analysis of Hydrogen Distribution Alternatives for Road Transport in Slovenia
Abstract:Hydrogen is considered one of the key energy carriers of future low-carbon energy systems and represents an important solution for decarbonizing sectors where direct electrification is technically or economically challenging. One of the major challenges in establishing a hydrogen economy is the efficient distribution of hydrogen, as different transportation methods significantly affect supply costs and the development of the required infrastructure. The aim of this master's thesis is to develop a techno-economic model for the comparative evaluation of hydrogen distribution alternatives for road transport in Slovenia and to determine the conditions under which individual transportation options represent the most economically feasible solution. The study focused on two of the most common hydrogen transportation methods: the transport of compressed hydrogen by trucks and hydrogen transport through pipelines. The analysis compared scenarios of centralized hydrogen production in Ljubljana and Krško and evaluated the influence of production site location on the supply costs of the planned hydrogen refueling station network in Slovenia. For truck transportation, the impact of different hydrogen compression pressures (350 bar and 540 bar) on transport capacity and costs was assessed, while for pipeline transportation, different pipeline diameters were evaluated with respect to investment and operating costs. The methodological approach was based on a comprehensive literature review, the development of mathematical models for estimating capital and operating costs, and a comparative techno-economic assessment of the selected scenarios. The Levelized Cost of Hydrogen Transportation (LCOHT) was used as the main economic indicator for comparing the alternatives. In addition, a sensitivity analysis was performed to evaluate the influence of key technical and economic parameters on overall hydrogen distribution costs. The results indicate that transporting hydrogen from Ljubljana via a pipeline with a diameter of 100 millimeters is the most economically favorable of the solutions analyzed. Central Slovenia (specifically Ljubljana in this case) is the optimal location for hydrogen production due to the ease of configuring the pipeline system or truck routes and the accessibility of other locations. The results also show that, when transporting hydrogen by truck, compressing the gas to 350 bar is cheaper than compressing it to 540 bar, regardless of the location. A sensitivity analysis demonstrated that pipeline transport remained the more cost-effective option across the range of parameter variations examined. Furthermore, it was found that for truck transport, fuel price is the most significant factor influencing the final cost of hydrogen transport, whereas for pipeline transport, the cost of the piping material is the most important factor.
