UPORABA SINTETIČNEGA PLINA PRI SHRANJEVANJU ELEKTRIČNE ENERGIJE

AŽMAN, GORAZD (author), Pantoš, Miloš (mentor)

Magistrska naloga obravnava pretvorbo električne energije v sintetični plin za namene shranjevanja. V prvem delu naloge sta predstavljena elektroenergetski in plinovodni sistem. Prvi del se konča s primerjavo obeh sistemov ter razlago odvisnosti Evrope in Slovenije od obeh energentov in njune soodvisnosti. V drugem delu so najprej obravnavane možnosti shranjevanja električne energije, kot so najbolj razširjene elektrarne s črpalno akumulacijo in baterijski hranilniki. Ta del se konča s podrobnejšo analizo pretvorbe električne energije v plin. Dobimo vpogled v tehnologije, ki so na voljo, njihovo primernost za širšo rabo in možne načine uporabe. V tretjem, zadnjem delu so najprej predstavljene metode za vrednotenje energetskih postrojev, od neto sedanje vrednosti in notranje stopnje donosa projektov do uravnoteženih stroškov skladiščenja. Predstavljene metode so v nadaljevanju uporabljene pri ekonomski analizi, ki poda informacijo o ekonomski upravičenosti naložbe v sisteme pretvorbe električne energije v zemeljski plin.

Abstract

Master’s thesis deals with power to gas energy storage solutions. Electric power systems and natural gas systems are presented in the first part of the thesis. This part concludes with a comparison of the two systems, European and Slovenian dependency on both electricity and natural gas and interdependency between the two. The second part explores different electric energy storage technology methods, among which pump hydro storage and electrochemical energy storage batteries are most common. Further on an in-depth analysis of power to gas method is presented. It provides insight into power to gas technologies, their availability, maturity and possible ways of use. The third part focuses on different methods for evaluation of various energy projects. It covers net present value calculation, internal rate of return and levelized cost of storage. These methods are then used in analysis, resulting in the presentation of power to gas energy storage profitability.
