Abstract

Geotermalna energija postaje sve značajnije u kontekstu obnovljivih izvora energije. Iako je
povijesno bila ograničena na geološki aktivnija područja, napretkom tehnologije, omogućena
je dostupnija primjena. Geotermalna toplinska energija je ekološki prihvatljiva jer ne stvara
emisije stakleničkih plinova te je stabilna i pouzdana jer ne ovisi o vremenskim uvjetima ili
sezonskim promjenama. Iako inicijalni troškovi mogu biti visoki, dugoročno gledano
geotermalna toplinska energija može biti ekonomična. Kombinacijom centraliziranog
toplinskog sustava s geotermalnom toplinskom energijom dobije se sustav koji je održiv i
ekološki prihvatljiv.
U sklopu ovog rada razmatrana su tehnička rješenja za toplinsku opskrbu Borovog Naselja i
naselja Olajnica u Vukovaru, primjenom geotermalnih toplinskih izvora te centraliziranog
toplinskog sustava. Slučajevi su se temeljili na udaljenosti geotermalnog izvora energije u
odnosu na glavno postrojenje CTS-a te kako bi se najbolje odredilo moguće rješenje koristila
se tehno – ekonomska analiza. Za naselje Olajnica i Borovo Naselje napravljena su za svaki
slučaj 4 scenarija gdje je varirala udaljenost geotermalnog izvora: 0 m, 500 m, 1000 m i 2000
m. Za obje lokacije su se promatrali slučajevi kada su postojale promjene u cijeni investicije,
potražnji toplinske energije, prodajne cijene toplinske energije. Korištenjem neto sadašnje
vrijednosti (engl. Net Present Value, NPV), unutarnje stope povrata (engl. Internal Recovery
Rate, IRR), indeksa profitabilnosti (IP) te metodom otplate (engl. Payback, PB) provedena je
ekonomska analiza za isplativost navedenih scenarija

Abstract (english)

Geothermal energy is becoming increasingly important in the context of renewable energy
sources. Although it was historically limited to geologically active areas, advances in
technology have made it available for use. Geothermal heat energy is environmentally friendly
because it does not generate greenhouse gas emissions and is stable and reliable because it does
not depend on weather conditions or seasonal changes. Although the initial costs can be high,
in the long run geothermal heat energy can be economical. Combining a centralized heating
system with geothermal heat energy results in a system that is sustainable and environmentally
friendly.
As part of this work, technical solutions for the heat supply of Borovo Naselje and the Olajnica
settlement in Vukovar were considered, using geothermal heat sources and a centralized heat
system. The cases were based on the distance of the geothermal energy source in relation to
the main plant of DH network, and to determine the best possible solution, a techno-economic
analysis was used. For the settlements of Olajnica and Borovo Naselje, 4 scenarios were created
for each case where the distance of the geothermal source varied: 0 m, 500 m, 1000 m and 2000
m. For both locations, cases were observed when there were changes in the investment price,
demand for thermal energy, selling prices of thermal energy. Using the Net Present Value
(NPV), the Internal Recovery Rate (IRR), the profitability index (IP) and the payback method
(PB), an economic analysis was performed for the profitability of the mentioned scenarios.
