Evaluation of uncertainty in the life cycle assessment of well-to-tank and combustion greenhouse gas emissions of various transportation fuels
Download2016-01-01
Di Lullo, Giovanni, Zhang, Hao, Kumar, Amit
Growing concern over climate change has created pressure on the oil and gas industry to reduce their greenhouse gas emissions (GHG). There have been multiple well-to-tank + combustion (WTT+C) studies that have examined various crude oils in an attempt to determine their GHG emission intensities....

This study explores the hydrothermal liquefaction (HTL) of wood chips to bio-crude followed by upgrading to diluents, which are used to transport bitumen through pipelines. In this study, we considered a 2000 dry t day-1 plant capacity with two scenarios. The first scenario uses hydrogen for...

Identifying Critical Corridors During an Area-Wide Disruption by Evaluating Network Bottleneck Capacity
Download2021-07-24
Ohi, Sabrena Jahan, Kim, Amy M.
This paper applies the min-cut max-flow theorem combined with a grid cell disruption method over a large transportation network, to identify the importance of network locations in providing travel capacity when a community is evacuating (say, from wildfire). We develop metrices that look at the...

Life cycle assessment of greenhouse gas emissions from Canada’s oil sands derived transportation fuels
Download2015-01-01
Nimana, Balwinder S., Canter, Christina E., Kumar, Amit
A comprehensive life cycle assessment (LCA) for transportation fuels (gasoline, diesel, and jet fuel) derived from Canada’s oil sands was conducted, and all the current possible pathways from bitumen extraction to use in vehicles were explored. Authors, in earlier studies, have presented the...

Wong, Alain, Zhang, Hao, Kumar, Amit
Purpose Governments around the world encourage the use of biofuels through fuel standard policies that require the addition of renewable diesel in diesel fuel from fossil fuels. Environmental impact studies of the conversion of biomass to renewable diesel have been conducted, and life cycle...

Reconstructing an Emergency Evacuation by Ground and Air the wildfire in Fort McMurray, alberta, Canada
Download2019-11-12
Woo, M., Hui, K. T. Y., Ren, K., Gan, K. E., Kim, A.
The May 2016 wildfire of Northern Alberta – the costliest wildfire disaster in Canadian history to date – led to an area-wide evacuation by road and air. Traffic count and flight data were used to assess the characteristics of the evacuation, including estimating people movements by vehicle and...

Techno-economic and life cycle assessment of lignocellulosic biomass-based thermochemical conversion technologies: A review
Download2015-01-01
Patel, Madhumita, Zhang, Xiaolei, Kumar, Amit
Bioenergy derived from biomass provides a promising energy alternative and can reduce the greenhouse gas (GHG) emissions generated from fossil fuels. Biomass-based thermochemical conversion technologies have been acknowledged as apt options to convert bioresources into bioenergy; this bioenergy...

Towards establishing effective commercial driver training standards: analysis of industry opinions from Alberta
Download2019-11-12
Gargoum, S. A., Kim, A. M., Zhang, H., Qiu, T. Z.
Commercial driver licensing programs ensure that drivers have the appropriate skills to perform their duties in a safe and efficient manner. Establishing such standards with good compliance requires understanding industry professionals’ opinions on aspects of current training. In this paper...

Uncertainty in well-to-tank with combustion greenhouse gas emissions of transportation fuels derived from North American crudes
Download2017-01-01
Di Lullo, Giovanni, Zhang, Hao, Kumar, Amit
Many studies have calculated deterministic point estimates of well-to-combustion (WTC) emissions of transportation fuels from crude oil in an attempt to determine which crude oils have lower or higher emissions. However, there is considerable variation in the published results, resulting in...
