Effect of copper contamination at the cathode in Cu-Cl electrolyzers for hydrogen production
(2020-04-01)
In this work the effects of copper contamination on the coulombic and voltage efficiency of the hydrogen evolution reaction (HER) via the Cu-Cl thermochemical cycle are investigated. A novel proton pump configuration was ...
Experimental investigation and analyses of continuous type hybrid photoelectrochemical hydrogen production systems
(2016-01-01)
Hydrogen is a highly versatile energy carrier that may become one of the key pillars to support the future CO2-free energy infrastructure. When used in fuel cells, H2 is converted to water and it gives little or zero exhaust ...
Design and evaluation of integrated waste to energy multigenerational systems
(2022-04-01)
This thesis study develops three renewable energy-based waste-to-energy multigeneration systems and examine them thermodynamically and economically. The first system uses solar-based energy and animal manure waste, and the ...
Evaporative drying of cupric-chloride droplets in a thermo-chemical cycle of hydrogen production
(2008-04-01)
This thesis develops analytical and numerical solutions that predict behavior of Cupric-Chloride droplets undergoing spraying and drying processes. Cupric-Chloride (CuCl2) is present as molten salt and slurry within the ...
Evaporative drying of cupric-chloride droplets in a thermo-chemical cycle of hydrogen production
(2012-08-01)
In this thesis, new empirical correlations that predict the behaviour of Cupric-Chloride
droplets undergoing spraying and drying processes are developed. Cupric-Chloride is a chemical
compound with the formula CuCl2 that ...
Thermodynamic anaysis of an integrated photovoltaic system for hydrogen and methanol production
(2012-06-01)
A solar based integrated system for hydrogen and methanol production is investigated. Energy and exergy analyses of a hydrogen production plant, thermodynamic assessment of methanol synthesis plant, and exergy analysis of ...
Energy, exergy and cost analyses of nuclear-based hydrogen production via thermochemical water decomposition using a copper-chlorine (Cu-CI) cycle
(2008-04-01)
In this thesis the Copper-Chlorine (Cu-CI) thermochemical cycle and its components as well as operational and environmental conditions are defined, and a comprehensive thermodynamic analysis of a Cu-CI thermochemical cycle, ...
Heat and fluid flow analysis in a molten CuCl heat exchanger
(2009-10-01)
The Cu-Cl thermochemical cycle is a promising method to generate hydrogen
as a clean fuel for human use in the future. The cycle can be coupled to nuclear
reactors to supply its heat requirements. The cycle generates ...
Electrochemical analysis of CuCl/HCl electrolyser
(2015-10-01)
This thesis presents an electrochemical study on a CuCl/HCl electrolyser which is the hydrogen generation step of the CuCl thermochemical hydrogen production cycle. The anode electrolyte is solution of 2 mol.l−1 CuCl(aq) ...
Thermodynamic performance assessment of three biomass-based hydrogen production systems
(2010-04-01)
Hydrogen is likely to be an important energy carrier in the future. It can be produced by the steam reforming of natural gas, coal gasification and water electrolysis among other processes. However current processes are ...
