Abstract:
Heavy-duty trucks are in idle operation during long periods of time, providing the vehicles with electricity via the alternator at standstill. Idling trucks contribute to large amounts of emissions and high fuel consumption as a result of the low efficiency from fuel to electricity. Auxiliary power units, which operate independently of the main engine, are promising alternatives for supplying trucks with electricity. Fuel cell-based auxiliary power units could offer high efficiencies and low noise. The hydrogen required for the fuel cell could be generated in an onboard fuel reformer using the

Abstract:
<p>The topic of this thesis is the study of energy storage systems operating with wind power plants. The motivation for applying energy storage in this context is that wind power generation is intermittent and generally difficult to predict, and that good wind energy resources are often found in areas with limited grid capacity. Moreover, energy storage in the form of hydrogen makes it possible to provide clean fuel for transportation. The aim of this work has been to evaluate how local energy storage systems should be designed and operated in order to increase the penetration and value of win

Abstract:
Solar Energy and Hydrogen (energy carrier) are possible replacement options for fossil fuel and its associated problems of availability and high prices which are devastating small, developing, oil-importing economies. But a major drawback to the full implementation of solar energy, in particular photovoltaic (PV), is the lowering of conversion efficiency of PV cells due to elevated cell temperatures while in operation. Also, hydrogen as an energy carrier must be produced in gaseous or liquid form before it can be used as fuel; but its‟ present major conversion process produces an abundance of

Abstract:
The member states of European Union aim to promote the reduction of harmful emissions. Emissions from combustion processes cause effects on human health and pose environmental issues, for example by increasing greenhouse effect. There are two ways to reduce emissions; one is to promote renewable energy sources and the other to utilize more effectively the available fossil fuels until a long-term solution is available. Hence, it is necessary to strive for CO2 mitigation technologies applied to fossil fuels. Low natural gas prices together with high energy efficiency have made gas turbines popul

Aluminum is one of the most active metals with high affinity to oxygen. In reality however, its reactivity is drastically reduced by the presence of a nanometer-thin oxide film which prevents (or slows down) its corrosion in environments in which the pH ranges from about 4 to 9. Increased reactivity and uniform corrosion is observed typically only in high alkaline or high acidic solutions in which the film dissolves. It has been recently discovered at UBC that the passivation of aluminum in aqueous solutions of neutral and near-neutral pH can be prevented when Al is mechanically alloyed with a

New control schemes need to be implemented to reduce these effects and ensure the stable operation of the power system. Storage systems emerged as a crucial component in the management of energy from the stand point of renewable sources, allowing energy to be stored or released into the grid whenever the power demand cannot be fulfilled.

In this work, three different operating modes (adiabatic, isothermal, Partially-insulated) of a continuous hydrogen generation system using the NaBH4 hydrolysis reaction are explored. Partially-insulated operation is recommended for this system since it has a higher outlet temperature and lower temperature distribution in reactor, which both mitigate the NaBO2 precipitation problem so that a larger energy densit

Synthesized nano aluminum hydroxide promotes hydrogen generation rapidly up to 95 % yield without using strong base within 90 second. Aluminum hydroxide soaking 1 hour in water before adding aluminum powder is proved to be a more effective way than those of directly mixing process. That is considered to be due to that more hydroxyl

It proves that the hydrogen generation rate from Al/water system is higher when Al(OH)3 contains residual NaOH. Through the change of pH value, ratio of Al(OH)3 to Al/water, and consecutive addition of Al powders to the Al/water system, we have higher hydrogen generation rate when OH- concentration is higher.
