Development of a new hybrid photochemical/electrocatalytic water splitting reactor for hydrogen production: design, analysis and experiments
(2012-01-01)
Solar-driven water splitting combines several attractive features for sustainable
energy utilization. The conversion of solar energy to a type of storable energy has crucial
importance. An alternative method to hydrogen ...
Investigation of sustainable hydrogen production from steam biomass gasification
(2010-12-01)
Hydrogen is a by-product of the gasification process and it is environmentally friendly with respect to pollution and emission issues when it is derived from a CO2-neutral resource such as biomass. It is an energy carrier ...
Modeling, analysis and optimization of integrated energy systems for multigeneration purposes
(2013-08-01)
Energy use is directly linked to well-being and prosperity across the world. Meeting the growing demand for energy in a safe and environmentally responsible manner is an important challenge. There are around seven billion ...
Development and analysis of alternative thermochemical cycles for hydrogen production
(2021-12-01)
Production of carbon-free fuels as alternatives for fossil fuels is a promising approach for controlling climate change and global warming. Hydrogen is considered as the key energy carrier of the future when it is produced ...
Experimental investigation of an integrated solar driven wastewater treatment system for trigeneration applications
(2018-08-01)
Hydrogen is a promising alternative as an energy carrier (and carbon-free fuel) to meet the global power demand. Hydrogen production systems can efficiently harvest energy from renewable sources. Even though photo-electrochemical ...
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 ...
Development of thermodynamic cycles for sodium-cooled-fast reactors.
(2013-12-01)
Currently, one engineering challenge is designing Generation IV (GEN-IV) Nuclear Power Plants (NPPs) with significantly higher thermal efficiencies compared to current NPPs, and to match, or at least to be close to, the ...
Monte Carlo simulations for the purpose of efficiency curve calibration for the Fastscan whole body counter
(2015-08-01)
In order to be able to qualify and quantify radiation exposure in terms of dose, a Fastscan whole body counter must be calibrated correctly. Current calibration methods do not take the full range of body types into ...
Optimization of plastic scintillator thicknesses for online beta detection in mixed fields
(2010-12-01)
For efficient beta detection in a mixed beta gamma field, Monte Carlo simulation models have been built to optimize the thickness of a plastic scintillator, used in whole body monitor. The simulation has been performed ...
Analysis and optimization of fuel cell based integrated powering systems for clean rail applications
(2019-08-01)
In this thesis, proposals of novel integrated fuel cell powering systems for cleaner railway applications are presented and analyzed thermodynamically. Both energy and exergy analyses are conducted on these systems for ...
