Abstract

Regulatorni okvir postavljen od Međunarodne pomorske organizacije s ciljem smanjenja
ukupnih emisija stakleničkih plinova, izazvanih pomorskim prometom, potiče na istraživanja
alternativnih rješenja brodskih energetskih sustava. Brodovi u priobalnoj plovidbi zahtijevaju
posebnu pozornost jer prometuju u blizini naseljenih mjesta, čime je njihov relativni utjecaj na
ljudsko zdravlje potencijalno veći od prekooceanskih brodova. U ovom diplomskom radu
analizirane su mogućnosti upotrebe vodika kao energenta u priobalnom brodskom prometu
prema ekološkim i ekonomskim kriterijima. Analiziran je cjeloživotni ugljični otisak različitih
konfiguracija energetskog sustava (za dizelsko gorivo i vodik) putničkog broda Prizna koji
plovi na relaciji Prizna-Žigljen u Republici Hrvatskoj. Analiza je provedena u programskom
paketu GREET 2020. U obzir su uzeti svi važniji procesi uključujući proizvodnju i distribuciju
pogonskog goriva, proizvodnju osnovnih komponenata brodskog energetskog sustava te samu
eksploataciju plovila. Za svaku energetsku konfiguraciju izračunat je cjeloživotni ugljični
otisak te je napravljena analiza i usporedba ukupnih cjeloživotnih troškova. Šira uporaba vodika
u pomorskom prometu zahtijeva smanjenje troškova njegovog dobivanja, kao i potvrdu od
strane nadležnih klasifikacijskih društava da je sigurnost takvih energetskih sustava barem na
razini postojećih. Pri tome valja istaknuti da su pravila klasifikacijskih društava koja bi
prepoznala vodik kao gorivo budućnosti još uvijek u fazi razvoja.

Abstract (english)

Regulatory framework set by the International Maritime Organization, with an aim to reduce
emissions caused by marine transportation, motivates research into ship alternative powering
options. This is particularly important for coastal vessels due to their operation in inhabited
areas and potentially higher effect on human health, compared to long-distance shipping. In this
master thesis, viability of hydrogen as an alternative fuel has been analysed from the
environmental and economic viewpoint. Life cycle carbon footprint of a passenger vessel
Prizna, operating at Prizna – Žigljen ferry route in Croatia has been calculated, for a diesel
engine-powered vessel and its alternative powered by hydrogen. The analysis has been
performed by means of GREET 2020 software. All important processes like fuel recovery and
distribution, manufacturing of power system components, fuel combustion, etc. were taken into
account. For each of the power system configurations, besides lifetime emissions, lifetime costs
have also been determined and analysed. Wider applicability of hydrogen as a marine fuel
requires decrease of its production costs as well as safety approval of relevant classification
societies which will guarantee at least the same safety level as in case of existing energy
systems. It should be noted that the rules of classification societies, that would recognize
hydrogen as a key fuel in the future, are still undevelopted.
