Engineering Design of a Modular Hydrogen Production System

The utilization of water electrolysis for hydrogen production is expected to increase significantly in the upcoming decades. Modular system design offers great advantages for emerging markets, whilst providing the necessary flexibility in capacity that intermittent renewable energy sources require. Literature research reveals little information...

Heat production in Alkaline Capillary-Fed Water Electrolysis

This master thesis introduces a recently surfaced method to produce hydrogen and oxygen using alkaline water electrolysis. A hydrophilic porous diaphragm is used that can feed electrolyte laterally to two porous electrodes that are placed against it. Consequently, hydrogen and oxygen are produced directly at the electrodes without any bubble...

Aircraft Integration of Air-Based Thermal Management Systems for Propulsive Fuel Cell Systems

Hydrogen is seen as a potential energy carrier for the next generation of aircraft that will be more climate-friendly than the previous generation of kerosene-powered aircraft. Two types of hydrogen-based propulsion systems are currently foreseen for such aircraft: hydrogen combustion and hydrogen fuel cell. In addition to producing useful...

Preliminary design methods for the thermal management of fuel cell powered aeroengines

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...

Distribution grid planning considering sector coupling and waste heat recovery

This thesis work investigates and provides an analysis of the potential benefits of an electricity - gas - heat integrated energy system, putting extra focus on the waste heat potential from fuel cells and electrolysers. The main focus is given to the low-voltage distribution grid level, and a case study is presented for the Drechtsteden...

Green Hydrogen for Residential Heating and Agricultural Mobility in Rural Areas: Socio-technical analysis of a hydrogen based energy system in Oudeschip

The Dutch Government is picking up the pace in the energy transition. However, the expansion of wind generation is facing congestion challenges, and the decarbonization of household heating and agricultural mobility proves that electrification is not always an option. These challenges occur together in rural areas like Oudeschip. <br/>Hydrogen...

Sensing ultraviolet light emission from hydrogen flames: Flame detection and flame monitoring in CO2 emission free domestic boilers

As a contribution to the decarbonisation of domestic heating, the graduation project investigates the feasibility of the application of UV sensor technology for flame detection and flame monitoring in hydrogen-powered domestic gas boilers. The research includes empirical studies and an analytical approach to describe influences on the sensor...
