“…While the majority of the fuel savings achieved in the work of [19] are a consequence of the reduction in the speed of the ship, the use of SOFCs provides additional benefit to the system's operations. Similary, in the work proposed by [2], the largest share of the energy demand is still provided by two-stroke dual-fuel Diesel engines, but a GT-SOFC hybrid unit is connected to the same switchboard in a full-electric system, and can hence contribute to the ship's energy demand for both hotel load and propulsion. The high efficiency of the system makes it suitable for fulfilling EEDI regulations even for phase 4, related to ships built after 2040.…”

“…This highlights the increased effort required by the future designers and operators of these vessels. Similarly, on the same time-scale, Panama flagged vessels emitted the most amount of CO 2 (~117E6 tons), followed by Liberian (~92E6 tons) and Marshall Islands (~79E6 tons) flagged vessels [4]. This represents the increased importance that the flag states have in enforcing IMO regulations through their regulatory control.…”

Review on the Safe Use of Ammonia Fuel Cells in the Maritime Industry

In April 2018, the International Maritime Organisation adopted an ambitious plan to contribute to the global efforts to reduce the Greenhouse Gas emissions, as set by the Paris Agreement, by targeting a 50% reduction in shipping’s Green House Gas emissions by 2050, benchmarked to 2008 levels. To meet these challenging goals, the maritime industry must introduce environmentally friendly fuels with negligible, or low SOX, NOX and CO2 emissions. Ammonia use in maritime applications is considered promising, due to its high energy density, low flammability, easy storage and low production cost. Moreover, ammonia can be used as fuel in a variety of propulsors such as fuel cells and can be produced from renewable sources. As a result, ammonia can be used as a versatile marine fuel, exploiting the existing infrastructure, and having zero SOX and CO2 emissions. However, there are several challenges to overcome for ammonia to become a compelling fuel towards the decarbonisation of shipping. Such factors include the selection of the appropriate ammonia-fuelled power generator, the selection of the appropriate system safety assessment tool, and mitigating measures to address the hazards of ammonia. This paper discusses the state-of-the-art of ammonia fuelled fuel cells for marine applications and presents their potential, and challenges.

“…In the existing literature, FTA has widespread applicability [50,70], with many publications reviewing the applicability of the method [71,72]. In the maritime sector, FTA was employed to investigate the availability of a large ethane carrier hybrid system that includes an ethane-powered SOFC for the electric demands of the vessel [73]. Others have investigated the safety enhancement of a cruise ship lubricating oil system using FTA [74].…”

Recently, the shipping industry has been under increasing pressure to improve its environmental impact with a target of a 50% reduction in greenhouse gas emissions by 2050, compared to the 2008 levels. For this reason, great attention has been placed on alternative zero-carbon fuels, specifically ammonia, which is considered a promising solution for shipping decarbonisation. In this respect, a novel ammonia-powered fuel-cell configuration is proposed as an energy-efficient power generation configuration with excellent environmental performance. However, there are safety and reliability concerns of the proposed ammonia-powered system that need to be addressed prior to its wider acceptance by the maritime community. Therefore, this is the first attempt to holistically examine the safety, operability, and reliability of an ammonia fuel-cell-powered ship, while considering the bunkering and fuel specifications. The proposed methodology includes the novel combination of a systematic preliminary hazard identification process with a functional and model-based approach for simulating the impact of various hazards. Furthermore, the critical faults and functional failures of the proposed system are identified and ranked according to their importance. This work can be beneficial for both shipowners and policymakers by introducing technical innovation and for supporting the future regulatory framework.
