Energy and cost analysis of a hydrogen driven high speed passenger ferry

Abstract

BACKGROUND: Norway is facing the challenge of reducing transport emissions. High speed crafts (HSC) are the means of transport with highest emissions. Currently there is little literature or experience of using hydrogen systems for HSC. OBJECTIVE: Evaluate the economic feasibility of fuel cell (FC) powered HSC vs diesel and biodiesel today, and in a future scenario, based on real world operation profile. METHOD: Historical AIS position data from the route combined with the speed-power characteristics of a concept vessel was used to identify the energy and power demand. From the resulting data a suitable FC system was defined, and an economic comparison made based on annual costs including annualized investment and operational costs. RESULTS: HSC with a FC-system has an annual cost of 12.6 MNOK. It is 28% and 12% more expensive than diesel and biodiesel alternative, respectively. A sensitivity analysis with respect to 7 key design parameters indicates that highest impact is made by hull energy efficiency, FC system cost and hydrogen fuel cost. In a future scenario (2025-2030) with moderate technology improvements and cost development, the HSC with FC-systems can become competitive with diesel and cheaper than biodiesel. CONCLUSIONS: HSC with FC-systems may reach cost parity with conventional diesel in the period 2025-2030.

Decarbonizing energy islands with flexibility-enabling planning: The case of Santiago, Cape Verde

“…Upper RES-shares limits can be imposed with (78) as justified by progressive energy transitions. Contrarily, minimum requirements can be established with ( 79)- (80) in the form of milestones.…”

“…The estimated required hydrogen satisfying the demand of the boats vary widely depending on the source. Assuming to use an electrolyzer with a 70% efficiency, the required electricity would be 25, 625, and 840 MWh/day according to [80][81][82], respectively. Thus, we chose 840 MWh/day as the worst case scenario and allow 600 MW of solar (or 2% of the land surface) and keep the 100 MW limit for HPS according to the previous sensitivity analysis.…”

AIS-Based Estimation of Hydrogen Demand and Self-Sufficient Fuel Supply Systems for RoPax Ferries

“…While this report provides a general indication of competitiveness, route and location-specific aspects, such as the specific operational and energy use profile or site-specific weather conditions, were not considered. Aarskog et al presented an energy and cost analysis of a hydrogen-driven high-speed passenger ferry in Norway [17]. An AIS-based energy use profile and cost calculations were aligned with the installed equipment of the specific ship.…”

Zero emissions wellboat powered by hydrogen fuel cells hybridised with batteries

“…13 There are also several studies on applying hydrogen fuel cells in ships from a theoretical point of view. [25][26][27][28][29][30][31] Some studies focus on the application of fuel cells in yachts, 32 research vessels, 33 LNG tankers, 34 oceanographic vessels, 6 ferries, [35][36][37][38][39] and tourist boats. 40 In Norway, the number of orders for low or free emissions ships has increased in the shipyards in recent years and Norwegian grants have supported the design and construction of hybrid propulsion vessels for aquaculture.…”
