Steneker, Tijmen (author)The petrochemical industry accounts for approximately 20% of global industrial CO2 emissions. Ethylene manufacturing is one of the major components and has a high carbon footprint. This study explores the use of proton-conducting electrochemical cells (PCECs) for ethylene production - the WINNER process. This non-oxidative dehydrogenation (NODH)...master thesis 2023

Scoccimarro, Antonio (author)Hydrogen fuel cells are set to play an important role in decarbonizing the aviation sector. They operate at higher efficiencies than turbine engines, but their low operating temperature requires a dedicated thermal management system. The added drag, weight and parasitic power of such a system has a high impact on aircraft performance and its...master thesis 2023

Malhotra, Dhruv (author)The issue of climate change has fostered the innovation of new technology in an attempt to curb the rising emissions, with the energy sector being one of the biggest contributors of carbon emissions. Renewable Energy has shown promise in reducing the emissions by up to 32 %. However the problem of intermittency of<br/>renewable energy sources is...master thesis 2022

Draijer, Pieter-Bas (author)The vast amounts of greenhouse gas (GHG) emissions, surging gas prices, and increasing proportion of intermittent energy sources force the energy sector to structurally modify the energy system. The reversible Solid Oxide Cell (rSOC) is considered to be part of the solution due to its high efficiency, good scalability, and ability to balance the...master thesis 2022

Cinek, Yavuz (author)The energy transition is one of the major challenges of the 21st century, impacting the way energy is generated, conserved and consumed. Energy generation becomes more and more decentralised, intermittency and fluctuations suddenly are becoming topics of interest within day-to-day life and energy system operators are facing many new obstacles...master thesis 2022

Swannet, Kilian (author)Interest grows rapidly in electric and hybrid electric aircraft. To determine the optimal performance and energy management required with such novel powertrain configurations, a knowledge-based aircraft and powertrain performance model is developed. The model is then used to set up an optimal control problem, which is transcribed to a non-linear...master thesis 2022

Koekkoek, Aron (author)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...master thesis 2021

van Laar, Ghislaine (author)This research examines the possible pathways and available technologies that will help the shipping sector to achieve the climate goals set by the IMO. Reaching these goals will require financial incentives and policies regarding sustainability. These policies need to describe regulations at both international and regional level given the...master thesis 2021

Frijters, Wout (author)A collaborative group comprising of the TU Delft, Deltion College and Dutch Electric Aviation Centre aim to develop a flying test bed for sustainable aviation. The collaborative group has acquired a Cessna 337F Skymaster with the intent to replace one of the engines with a retrofit hydrogen internal combustion engine. An ancillary engine will...master thesis 2021

Nuij, Gert-Jan (author)The CCNR will ensure that in 2050 inland ships do not emit any emissions. A PEM fuel cell system running on pure hydrogen could be a solution. However, the new system imposes some difficulties on the design of the inland ship. A calculation model is created to evaluate inland ships with this system and research these difficulties. The...master thesis 2021

Vonhoff, George (author)The demand for air travel is increasing as more people gain access to commercial aviation. As the current generation of aircraft makes use of fossil fuel combustion, this growth results in an increase in the global emissions. This is at odds with the worldwide efforts of reducing the adverse effects of climate change. Therefore, advanced...master thesis 2021

Tomar, Saloni (author)Transport sector CO2 emissions are on the rise and responsible for nearly 30% of the EU’s total CO2 emissions (European Parliament,2019). An attractive way to reduce the CO2 emissions by transport is by changing the fuel used. Hydrogen is expected to play a key role in a clean, secure and affordable energy future (IEA). However, a clean,...master thesis 2020
