Development and analysis of a high temperature electrolyser for the Cu-Cl cycle for hydrogen production
(2017-01-01)
A number of thermochemical cycles have been investigated to produce hydrogen from water. However, most of these cycles operate at over 800°C. The relatively lower temperature (550°C) requirement and use of inexpensive ...

(2017-04-01)
This thesis proposes and investigates a new generation of photoelectrochemical cells for solar hydrogen production based on high temperature Solid Oxide Electrolysis Cells. Therefore, a set of experiments are designed to ...
Development and investigation of integrated solar systems for hydrogen and methanol production
(2018-04-01)
Implications of climate change, in particular the negative effects of greenhouse gas (GHG) emissions resulting from fossil fuel combustion, as well as the finite nature of fossil fuels necessitate the implementation of ...
Thermal management of the copper-chlorine cycle for hydrogen production: analytical and experimental investigation of heat recovery from molten salt
(2012-08-01)
Hydrogen is known as a clean energy carrier which has the potential to play a major role in addressing the climate change and global warming, and thermochemical water splitting via the copper-chlorine cycle is a promising ...
Mass transfer and particle dissolution in liquid-gas and solid-liquid flows: Application to hydrogen production processes.
(2013-10-01)
Many environmental problems are related to the production, transformation and use
of energy. Some of the concerns include, but are not limited to, acid rain, ozone depletion
and climate change. Therefore, “greener” ...
Modified Nafion membranes for hydrogen production in Cu-Cl thermochemical cycle
(2015-07-01)
The decomposition of water by a thermochemical cycle is a promising green method of producing hydrogen on a large scale. A thermochemical cycle is a combination of thermal and chemical reactions that ultimately leads to ...
Multiphase flow and chemical reactor thermodynamics for hydrolysis and thermochemical production
(2012-08-01)
Current techniques of hydrogen production (primarily reformation of fossil fuels) are
unsustainable, releasing CO2 into the atmosphere, as well as consuming limited reserves
of fossil fuels. The copper-chlorine cycle is a ...
