20.500.12556/RUL-181143 Hidravlični hranilnik energije Hydraulic energy storage device Današnjega življenja si ne moremo predstavljati brez vselej dostopne energije, predvsem električne. V diplomski nalogi je obravnavan problem shranjevanja električne energije, pridobljene iz obnovljivih virov. Ti viri namreč niso stalno razpoložljivi in jih je težko zanesljivo napovedati. Zaradi neenakomerne proizvodnje električne energije iščemo različne možnosti učinkovitega shranjevanja in kasnejše porabe. V diplomskem delu primerjamo električni in hidravlični hranilnik energije. Metodologija temelji na preračunih hidravličnega hranilnika in ekonomski analizi shranjene energije. Iz rezultatov je razvidno, da imajo električni baterijski sistemi krajšo življenjsko dobo in nižje investicijske stroške, hidravlični hranilnik pa veliko daljšo življenjsko dobo, zelo dobro reciklabilnost, vendar znatno višji investicijski strošek. We cannot imagine modern life without a constant supply of energy, particularly electricity. This thesis addresses the problem of storing electricity generated from renewable sources. These sources are not always available, and their output is difficult to predict reliably. Due to the irregular production of electrical energy, we are seeking various options for efficient storage and subsequent consumption. In this thesis, we compare electrical and hydraulic energy storage systems. The methodology is based on calculations of the hydraulic storage system and an economic analysis of the stored energy. The results show that electric battery systems have a shorter lifespan and lower investment costs, while hydraulic storage systems have a much longer lifespan and very good recyclability, but significantly higher investment costs. shranjevanje energije obnovljivi viri hranilniki energije električni akumulator hidravlični hranilnik energy storage renewable energy sources energy storage devices electrochemical battery hydraulic energy storage device true false false [D.
