Hydrogen as fuel for vessel propulsion

Ovaj diplomski rad obrađuje tematiku korištenja vodika kao goriva za pogon plovnog objekta. U radu je dan pregled regulativa Međunarodne pomorske organizacije kojima se nastoje smanjiti emisije štetnih plinova. Prezentiraju se alternativna goriva, kao što su vodik, amonijak, sintetički prirodni plin i metanol, koja nisu štetna ili su manje štetna za okoliš od konvencionalnih goriva, s posebnim naglaskom na vodiku. U radu su prikazani razni načini skladištenja vodika te se prezentiraju prednosti i mane istih te je dan pregled brodskih energetskih sustava pogonjenih vodikom i gorivnim člancima. Takav sustav se sastoji od gorivnog članka, baterije i elektromotora. U radu je opisan i brodski energetski sustav pogonjen vodikom i motorom na unutarnje izgaranje.The diploma thesis discusses using hydrogen as a fuel for a vessel propulsion system. An overview of the International Maritime Organization regulations on reducing harmful emissions of gases is presented. Alternative fuels, such as hydrogen, ammonia, synthetic natural gas and methanol, which are not harmful or less harmful than conventional fuels are discussed. Various ways of storing hydrogen and their advantages and disadvantages are presented and a vessel energy system powered by hydrogen and fuel cell is explained. Such a system consists of a fuel cell, a battery and an electric motor. A vessel energy system powered by hydrogen and an internal combustion engine is described
