Highly automated Unmanned Aerial Vehicles (UAVs) or "flying robots" are rapidly becoming an important asset to society. The last decade has seen the advent of an impressive number of new UAV types and applications. For many applications, the UAVs need to be safe, highly automated, and versatile. Safety is a prerequisite to allowing their use in...

High concentration hydrogen peroxide (HP) promises to be an economical and green alternative for hydrazine. However, it has only limited storage life, and addition of stabilizers must be avoided to preserve the high purity required for propellants. This work has investigated the mechanical fastening of normally dissolved stabilizers on the...

To reduce emissions from civil aviation, research is being conducted in lean premixed hydrogen combustors as part of the APPU project at the TU Delft. Next to mitigating CO2 emissions completely, these technologies have the potential to also reduce NOx emissions greatly, allowing for the future of civil aviation to become sustainable. However,...

A radical change of the energy system is required in light of the dramatic effects of human-induced climate change. In this perspective, a future renewable hydrogen energy system was proposed, where biogenic resources are ascribed relevant potential as source of biogenic hydrogen and biogenic carbon dioxide. In this light, the research brings...

Hydrogen is expected to be a significant force in this transition. Hydrogen can be produced using technologies that do not emit CO2 or other greenhouse gasses (“green H2”). Hydrogen can be transported in big quantities and long distances unlike electricity and can play the role of a clean fuel. The emerging hydrogen economy, which will be...

Urgent action is needed to decrease maritime emissions. The renewable wind energy sector must also decrease its life cycle greenhouse gas (GHG) emissions. Total GHG emissions from offshore wind turbines are approximately 120% more compared to onshore wind turbines. Moreover, it is estimated that Walk to Work (W2W) vessels are responsible for 3.3...

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...

Due to the demand for renewable energies, gasses likeH2 need to be detected with sensitive, accurate and fast detectors. The US Department of Energy has made a list of requirements that H2 sensors need to fullfill of which the minimum detectable concentration (0.1%) and the reaction time (one second) are challenging for current hydrogen sensors,...

This paper investigates the cost­-benefit, payload performance and technical feasibility of green storable upper stage design concepts on their potential implementation with existing launchers. Since the demand for reliable, safe, and cost­-effective transport to space is growing, it is necessary to find sustain­able rocket propellant solutions....

Over the last years, the urge to reduce the world’s air pollutants is rapidly growing. New possibilities in order to replace fossil fuels have been explored and one of them is the usage of green hydrogen. The Argentinian, North Patagonian, province of Río Negro, has a great potential to generate green hydrogen on a large scale, due to the...

The Port of Rotterdam is developing a hydrogen and CO2 pipeline bundle for industry in NRW. By applying a Multi-Criteria Analysis to this case, a model is created that evaluates this pipeline bundle against the criteria of the industry in North Rhine-Westphalia. The system analysis is used as the basis for the model, industry objectives are used...

In this thesis, we explore a proposal from Stedin that advocates heating the city of Stad aan `t Haringvliet with hydrogen rather than natural gas. Switching from natural gas to hydrogen presents plenty of unknown factors which must be properly evaluated for an accurate and realistic risk picture, including the danger of running out of hydrogen....

The European Green Deal states that it wants to develop 40 GW of electrolyzer capacity by 2030 in North Africa to combat climate change. Using PV power as the primary energy source, a system is designed that can produce green hydrogen and ammonia to investigate how the location and the capacity of the components can be optimized to produce at...

The green-hydrogen supply chain is part of the new energy business and will be operating in the new-energy markets. The new-energy markets are markets with volatile prices, and the prices are expected to become even more volatile in the future. A continuous-time model of the price and product flow dynamics is needed to quantify the value...

Shipping is, and will continue to be, the most important transportation method around the globe. A vital part of the logistic chain, it is also one of the main contributors to the worldwide CO2 emissions. Current propulsion technologies all rely on the same classic diesel driven technology, as diesel is widely available and has a high energy...

The aviation industry has grown at a steady rate of 5% per year over the past decades and is projected to continue this growth over the coming years. In sharp contrast stands the increasing concern with the reduction of the environmental impact of flying in the short term. To this end, a fuselage boundary layer ingesting propulsor powered using...

Implementing green alternatives in the heavy­-duty mobility market is required to reach the set climate goals of 2050 and decrease greenhouse gas emissions. Refuelling infrastructures based on alternative fuels such as hydrogen are not sufficiently available. This poses a barrier to large scale implementation and investment in new emission­ free...

The Gulf Cooperation Council (GCC) countries have one of the highest annual energy consumption per capita and rank within the top 10 countries with highest CO¬2 emissions. All of the countries have low levels of renewable energy share in the total energy consumption. Among these countries, UAE has been relatively proactive in promoting the use...
