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...

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...

Granular activated carbon sparking anaerobic digestion: the path to municipal sewage resource recovery
DownloadSpring 2023
Anaerobic digestion (AD) is an effective and economical technology that can convert organic pollutants to biomethane, playing a pivotal role in resource recovery and greenhouse gas emission control. However, the anaerobic treatment of municipal sewage under psychrophilic conditions faces...

Implementation and Evaluation of Spatiotemporal Prediction Algorithms and Prediction of Spatially Distributed Greenhouse Gas Inventories
DownloadFall 2011
Growing environmental concerns require monitoring and modelling of greenhouse gases. These modelling efforts require processing of massive datasets in a timely fashion. This, in turn, can lead to feasibility problems when estimating values of missing data points. This thesis examines and compares...
