A Techno-Economic Assessment of Sustainable Large Scale Hydrogen Production from Renewable and Non-Renewable Sources
DownloadFall 2016
In recent times, the imperative to mitigate greenhouse gas (GHG) emissions that emanate from a multitude of sectors in the global energy economy has achieved unprecedented and widespread consensus. Depending on the energy resource and method used to produce hydrogen, it offers a compelling...

Assessment of greenhouse gas reduction options for the iron, gold, and potash mining sectors
DownloadFall 2019
Canada has one of the world’s highest greenhouse gas (GHG) emissions per capita among developed countries and was the 10th largest global GHG emitter in 2017. Consistent with the Paris Agreement’s goal of controlling the temperature increase by 2°C to 1.5°C, Canada aims to reduce GHG emissions by...

Energy Return on Investment and Techno-economics of Pellet Production from Steam Pretreated Biomass
DownloadFall 2015
Utilization of raw ligno-cellulosic biomass for energy use is limited because of its low heating value and low yield per unit area of biomass. Pellets are densified and compressed form of biomass which has less moisture and higher energy density compared to raw biomass. Pellets are typically...

Enhancement of lignocellulosic feedstocks and biorefinery byproducts for composite and polymer applications
DownloadFall 2015
The volatility of the petroleum-based markets, increasing ecological concerns, and the accumulation of waste from the plastic industry have motivated a paradigm shift in research. Researchers are searching for sustainable, renewable, and competitive platforms ideally suited for replacement of...

Enhancing Anaerobic Digestion Efficiency of High Strength Wastes with Different Solid Contents
DownloadSpring 2023
Anaerobic digestion has been considered as a sustainable technology to treat a wide range of organic wastes and to recovery value-added products such as methane and fatty acids. However, several factors such as low temperature and high solids content of substrates would lead to the imbalance of...

Environmental and Performance Analysis of a 5kW Horizontal Axis Wind Turbine in East Central Alberta
DownloadSpring 2012
This thesis investigates the environmental and performance results of a 5kW horizontal axis wind turbine installed in east-central Alberta. Life cycle assessment (LCA) methodology was utilized to perform a comparative environmental impact study on three sizes of small wind turbines installed in...
