20.500.12556/DKUM-88312 Comparative analysis of direct operating costs: Conventional vs. hydrogen fuel cell 19-seat aircraft In this paper, a comparative analysis of direct operating costs between a 19-seat conventional and hydrogen-powered fuel cell aircraft is performed by developing a model to estimate direct operating costs and considering the evolution of costs over time from 2030 to 2050. However, due to the technology being in its early stages of development and implementation, there are still considerable uncertainties surrounding the direct operating costs of hydrogen aircraft. To address this, the study considers high and low kerosene growth rates and optimistic and pessimistic development scenarios for hydrogen fuel cell aircraft, while also considering the evolution of costs over time. The comparative analysis uses real flight and aircraft data for the airliner Trade Air. The results show that the use of 19-seat hydrogen fuel cell aircraft for air transportation is a viable option when compared to conventional aircraft. Additionally, the study suggests potential policies and other measures that could accelerate the adoption of hydrogen fuel cell technology by considering their direct operating costs. fuel cell aircrafts direct operating cost of aircraft 19-seat aircraft letala na gorivne celice neposredni operativni stroški letala 19-sedežno letalo true false true MDPI Angleški jezik Slovenski jezik https://www.mdpi.com/journal/sustainability Članek v reviji 2024-04-15 12:04:15 2024-04-15 12:04:17 2024-04-16 03:53:25 0000-00-00 00:00:00 2023 0 0 str. 1-20 iss. 14, [article no.] 11271 Vol. 15 July 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2023-06-01 2023-07-18 2023-07-19 656.7 161135363 10.3390/su151411271 2071-1050 sustainability-15-11271-v3.pdf sustainability-15-11271-v3.pdf 1 1D55ACC4FF63127A56953F324FF49C23 d8ce6d5f5766bffe82517c73ac11204925de45e77a6b797d2d9c9a78b3ff7835 6e31a80b-fb10-11ee-8f8b-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=178552 https://www.mdpi.com/2071-1050/15/14/11271 0 9089cd49-fb10-11ee-8f8b-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=178553 Fakulteta za gradbeništvo, prometno inženirstvo in arhitekturo 0 0 0
