A Long-Term Integrated Assessment of Cost, Water Consumption, and Greenhouse Gas Emissions of a Transition to a Low-Carbon Bitumen and Hydrogen Production
DownloadFall 2023
The growing demand for energy and the need for mitigation of greenhouse gas (GHG) emissions has led to increased interest from government, industry, and academia in the development of new low-carbon technologies for bitumen extraction and hydrogen production. In situ bitumen is a major...

A techno-economic assessment of hydrogen production from hydropower in western Canada for the upgrading of bitumen from oil sands
Download2016-01-01
Olateju, Babatunde, Kumar, Amit
The demand for hydrogen in conventional and unconventional oil refining industries is considerable. Currently, the predominant source of hydrogen is from fossil fuel production pathways, in particular, steam methane reforming (SMR), which incurs a significant greenhouse gas (GHG) emissions...

A techno-economic assessment of large scale wind-hydrogen production with energy storage in western Canada
Download2016-01-01
Olateju, Babatunde, Kumar, Amit, Secanell, Marc
Hydrogen production via steam methane reforming (SMR) dominates the supply to refining complexes worldwide, resulting in significant greenhouse gas (GHG) emissions. There is a considerable demand for clean hydrogen pathways that are economically competitive with SMR. The development of a 563 MW...

Atomic Force Microscopy Characterization of Hydrogen Terminated Silicon (100) 2x1 Reconstruction
DownloadFall 2015
Non-contact Atomic Force Microscopy (NC-AFM) is a Scanning Probe Microscopy tool offering unique non-perturbative analysis of surfaces and adsorbates at the atomic scale. AFM precisely oscillates a sharp tip above a sample. By monitoring the shift in resonance frequency of a quartz tuning fork...

Characterization of natural zeolite membranes for H2/CO2 separations by single gas permeation
DownloadFall 2011
Hoseinzadeh Hejazi, Sayed Alireza
Membrane-based processes have the potential to overcome the limitations of conventional hydrogen separation techniques such as high energy consumption and environmental concerns. Natural zeolite membranes have recently been shown to demonstrate apparent molecular sieving of H2 from H2/CO2...

Control of boundary slip by interfacial nanobubbles: A perspective from molecular dynamics simulations
Download2023-01-01
Ynag, Haichang, Zeng, Binglin, Zhang, Xuehua, Xing, Yaowen, Gui, Xiahui, Cao, Yijun
Enhancing boundary slip using interfacial nanobubbles (INBs) has gained significant interest in nanofluidic transport. In this study, we conducted a comprehensive investigation on the influence of INBs on boundary conditions for both smooth and rough substrates using molecular dynamics...
