Climate change, depletion of fossil fuels, and economic concerns are among the main drivers of sustainable energy transition. The Netherlands has drawn up ambitious goals in the energy transition. However, numerous studies have shown that there is a lack of space in the Netherlands to adapt to a 100% green economy. To solve this dilemma it is...

With the global increase in passenger traffic and growing popularity of long-haul routes over the Asia Pacific region and Atlantic Ocean, the possibility for hypersonic transport could become an attractive option to reduce flight time over long distance from 16-20 hours down to around 4-5 hours. In this thesis, a Multi-Disciplinary Optimisation...

Aviation is the backbone of our modern society. In 2019, around 4.5 billion passengers travelled through the air. However, at the same time, aviation was also responsible for around 5% of anthropogenic causes of global warming. The impact of the COVID-19 pandemic on the aviation sector in the short term is clearly very high, but the long-term...

After the space race to the Moon, Mars has been chosen the new destination to be explored by mankind. Cryogenic propellant is necessary to make space beyond the Moon accessible. Boil-off of cryogenic liquids raises the initial mass of spacecraft by increasing the amount of propellant required to carry-on. Therefore, mitigation of boil-off is key...

The amount of emissions produced by aviation resulting from the use of kerosene is raising concerns. Therefore, a main point of developments and research in the aviation sector is regarding the reduction of its climate impact. The climate impact of aviation can be reduced by making use of alternative fuels, such as liquid hydrogen. A suitable...

To reach the goals of the European Green Deal (CO2 emission reduction of 55% by 2030 and climate neutral by 2050), North-Western Europe has to import sustainable energy as locally produced renewable energy will not be sufficient to meet the total demand. This will be realised by importing green hydrogen from areas with a surplus of renewable...

Zero-carbon-dioxide-emitting hydrogen-powered aircraft have, in recent decades, come back on the stage as promising protagonists in the fight against global warming. Nevertheless, most recent studies agree that hydrogen aircraft would underperform their kerosene counterparts in terms of operative empty mass and specific energy consumption. The...

Increasing pressure on the reduction or elimination of the use of fossil fuels in shipping requires the application of new maritime fuel alternatives. Green and circular produced hydrogen as a maritime fuel in fuel cell systems offers a great solution for these concerns. A fuel cell system has a zero emission performance, solid state silent...

A large deployment of energy storage solutions will be required by the stochastic and non-controllable nature of most renewable energy sources when planning for higher penetration of renewable electricity into the energy mix. Various solutions have been suggested for dealing with medium- and long-term energy storage. Hydrogen and ammonia are...

The space community is currently focusing on defining system architectures able to perform multiple interplanetary missions to support deep space exploration. In particular, placing orbital propellant depots in strategic locations in space would allow to increase the useful payload mass at launch. Despite all the efforts that are being invested...

Within this thesis report the transition to LH2 infrastructure at the airport is tackled. Specifically, how the airport can develop and adopt the infrastructure needed for LH2 supply logistics, storage, and refueling is researched. This process can be defined as a socio-technical transition in which a new niche technology (LH2 aviation...

This work describes the benefits of exploiting cold hydrogen in a 2 MW liquid hydrogen-electric powertrain. Hydrogen is stored in a liquid state in the aircraft at its boiling point of 20 K (at 1 bar). Fuel cells require an input temperature of at least zero degrees Celsius to operate. The heating process can either be done by drawing current...

Solid Oxide Fuel Cell (SOFC) systems for aviation applications have been considered for their use as APUs or powertrains, as standalone systems or in combination with gas turbines, and both fueled by reformed Jet-A or by hydrogen. Most existing studies focus on powertrain performance modelling. In this work, traditional tube-and-wing regional...

Green hydrogen combined with PEM fuel cell systems is a viable option to meet the demand for alternative maritime fuels. However, hydrogen storage faces challenges, including low volumetric density, fire and explosion risks and transport challenges. We assessed over fifteen hydrogen carriers based on their maritime performance characteristics...

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)...

This thesis focuses on simulating the refuelling process for a liquid hydrogen-powered commercial aircraft. The liquid hydrogen is intended to flow from the refuelling truck, through a transfer line, into the aircraft’s tank using pressure feed. The numerical simulation was built upon an existing tank model, however it did not consider the...

Hydrogen's competitiveness as a sustainable energy carrier depends greatly on its transportation and storage costs. Liquefying hydrogen for these purposes offers benefits like purity, versatility, and higher density. However, current industrial hydrogen liquefaction processes face efficiency and cost challenges, with a second-law efficiency...

Green hydrogen is anticipated to be pivotal in the decarbonisation of global energy systems. For the Netherlands, both domestic production and imports of green hydrogen are believed to be needed for effective decarbonisation. Yet, significant uncertainty surrounds the cost discrepancy between domestic productions and initial imports, largely...

Climate change is a pressing issue. Hydrogen aircraft are an excellent alternative to current kerosene aircraft, and appear to be the most viable long-term solution for net-zero flight. One of the main challenges for hydrogen aircraft is to sustain a low boil-off rate. This research explores the solution of active cooling of the LH2 mixture in...
