Schenkel, Frank (author)
To achieve the emission goals set out by the International Maritime Organization in 2018. Low or zerocarbon fuels will have to be used. Ammonia is considered to be a possible candidate since it doesn’t contain carbon. This thesis will attempt to study two methods that characterize the closed-cylinder process of an internal combustion engine; the...

Hoeksma, Bram (author)
Currently, our society faces a pressing challenge: global warming. The solution lies in the energy transition, which replaces fossil fuels with clean sources. This requires a global effort across all sectors, including shipping. While a significant portion of shipping relies on polluting fuels, the European Union’s Green Deal aims for climate...

Jacobs, Isabelle (author)
This graduation thesis studies the CI combustion of ammonia and hydrogen in an ICE. It contains a review of the literature and a modeling study of the ignition and cylinder performance of the AmmoniaDrive test engine. AmmoniaDrive is a NWO-funded research project that aims to decarbonize shipping by introducing an ammonia-fuelled SOFC-ICE power...

Molhuizen, Max (author)
Battery electric vehicles (BEV) as opposed to internal combustion engine vehicles (ICEV) are seen as a viable solution for reducing transportation related environmental impacts. There are however advantages and disadvantages to both alternatives. Environmental life cycle assessments (LCA) are used to quantify the environmental lifecycle impact...

Böhme, Florian (author)
Mobile electronics or remote devices like sensors for the Internet of Things (IoT) require energy storage with increasing energy densities, approaching the limits of the widespread lithium batteries. At the same time, lithium batteries are subject to growing criticism about their environmental impact due to their raw materials and their mining...

Zuidgeest, Sven (author)
The current global fleet is still dependent on conventional fuels as energy source to transport goods to various places in the world. These conventional fuels, such as MGO or HFO, emit large amounts of greenhouse gasses and other pollutant emissions. Regulation concerning these emissions becomes stricter every day, therefore institutions and...

Several news items and short movies have appeared online recently, announcing that the AmmoniaDrive Consortium was awarded a prestigious NWO Perspectief grant. But what is the AmmoniaDrive research project? How does it contribute to combatting shipping-induced climate change? Who are in the consortium and why? And finally, what research...

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...

Sapra, H.D. (author)
Modern marine diesel engines operating on conventional marine fuels are unable to further reduce the adverse impact of ship emissions on the environment. Integration of a solid oxide fuel cell (SOFC) and internal combustion engine (ICE) equipped with an underwater exhaust (UWE) can provide the opportunity for mitigating ship emissions and...

Bosklopper, J.J. (author)
The maritime sector faces major challenges with increasing regulations from the International Maritime Organization (IMO) and national regulations for CO2, SOx and NOx. Innovative fuel types for maritime use are now under development by various stakeholders. Methanol shows considerable potential as one of the most promising for implementation in...

Reurings, Jeroen (author)
Emissions restrictions imposed by the International Maritime Organization (IMO) is forcing ship owners and builders to look into alternative fuels and prime movers. The high efficiency of fuel cells could help to decrease emissions in marine power generation. Solid oxide fuel cells (SOFCs) are the most fuel flexible among fuel cells, the high...

de Vries, Niels (author)
To achieve significant reduction in greenhouse gas emissions in shipping and enable ship owners to phase out fossil fuels entirely, renewable fuels, such as ammonia, play a crucial role. Ammonia is considered a balanced solution in terms of volumetric energy density and renewable synthetic production cost compared to other renewable fuels....

de Jong, Alieke (author)
Waterborn transport currently runs on diesel driven Internal Combustion Engines<br/>(ICE). To reduce Green House Gas (GHG) emissions an option is to shift towards<br/>alternative fuels, like alcohols. This thesis focusses on methanol in ICEs. The<br/>combustion of methanol in ICEs can be done in numerous manners, where fuel<br/>altering,...
