<div>With fuel cells making their way into the maritime sector, cooling systems are becoming a more important aspect of ship design with regard to power saving. Because fuel cells generate heat at a lower temperature, they require a cooling system that is comparatively larger than that of conventional power trains. Ship cooling system research...

New methods of ship propulsion are required to meet the targets for reducing global emissions of greenhouse gases. Hydrogen-powered fuel cells can be used to greatly reduce emissions, facilitating renewable shipping. Fuel cell durability is recognised as a large barrier to widespread fuel cell application. The goal of this graduation project is...

The maritime sector CO2 emissions are one of the contributors to the increase of the concentration of this gas in the Earth's atmosphere. One of the proposed solutions for reducing these emissions is the implementation of carbon capture technologies onboard vessels. Carbon capture technologies work on the principle of apprehending the carbon...

In the yachting decarbonisation by 2030, multiple fuels usage provides flexibility to ocean-crossing superyachts in a scenario where alternative fuels become progressively available worldwide. Hydrotreated vegetable oil (HVO) and methanol (MeOH) are selected among all sustainable fuels. The desired flexibility can be achieved with a multi-fuel...

Feasibility improvement of Solid Oxide Electrolysis (SOE) is required to accelerate technology development. The study aims to determine whether and under what conditions reversible operation can improve the techno-economic feasibility of a large-scale open-system SOE. The feasibility of reversibility is assessed under various scenarios and...

The research objective of this thesis is to simulate the dynamic behaviour of a proton exchange membrane (PEM) fuel cell system. The model will encompass the fuel cell stack and some simplified balance of plant components. It will focus on simulating the reactions of the cell and the system with regards to changes in the requested load.

In order to meet the shipping industry's emissions reduction goals, it is imperative to explore and adopt alternative marine fuels. Methanol (or methyl alcohol) is expected to play a large role in the future. However, current regulations limit the attractiveness of methanol as marine fuel due to the inability to use the space around a venting...

Chemicals within a chemical tanker need heating to keep the cargo above a desired temperature. This research focuses on the prediction of the fuel consumption used to heat the cargo. There are three methods discussed in this research: a physics-based model (PBM), a data-driven model (DDM) and a hybrid model (HM). The PBM is a model based on the...

The maritime sector is actively investigating new solutions for zero emissions in<br/>response to climate change. One of the promising options is hydrogen-based propulsion, but there are currently no prescriptive rules or legislation to approve the design of such innovative, unproven technology. The International Maritime Organization (IMO)...

Currently, the energy transition is a topic for discussion and many organizations are taking measures to reduce the effects of climate change. Armed forces are exempt of these new regulations on the grounds of national security, but some have already started taking steps to reduce the amount of harmful emissions. Due to the high efficiency and...

Mertens, Emily (author)
Global warming is a topic of major concern the last decade and for reason the IMO adopted a strategy to reduce the emissions of greenhouse gasses of vessels. In order to meet the IMO requirements ships propulsion systems need to become more sustainable. An option to reduce emission is the implementation of fuel cells running on hydrogen together...

In response to climate change, the marine sector is increasingly focused on the energy transition. New marine power plants operating more efficiently and on cleaner fuels are receiving significantly more attention. While the transition to different power plants and fuels results in reduced fossil fuel consumption and emissions, waste heat...

Pluijlaar, Dion (author)
This research was performed with the goal of giving insight if the Rijksrederij is able to operate part of their fleet on renewable methanol and fuel cells, in order to work towards their goal of operating with net zero CO2 emissions by 2030. This prompted a research question that focussed on both the renewable methanol supply and the technical...

The characteristics of a metal supported solid oxide fuel cell on methanol is analysed in as the power generator in a balance of plant consisting out of a reformer, combuster, heaters, pumps, turbines and tubes. The system is reviewed on performance regarding efficiency, power density, fuel utilization and viability for marine applications.

Ammonia (NH3) may reduce CO2 emissions from the marine industry as it is carbon-free and more energy-dense than hydrogen or batteries. Pure ammonia exhibits poor combustion characteristics, so several researchers have already operated small-scale internal combustion engines (ICEs) with ammonia-hydrogen blends. However, nitrogen oxides NOx and...

Bronkhorst, Philip (author)
The growth in the offshore wind industry sees an increased demand for offshore service vessels (OSVs). These vessels often operate in harsh conditions, and their performance is heavily dependent on their seakeeping characteristics. Conventional ship design processes fail to effectively consider seakeeping early in the design process, leading to...
