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 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...

Current uptake of 15N –labeled ammonium and nitrate in flooded and non-flooded black spruce and tamarack seedlings.
Download2009
Macdonald, S. Ellen, Islam, M. Anisul
We investigated the effects of flooding for three weeks on physiological responses and uptake of NH4+ and NO3- by black spruce (Picea mariana (Mill.) BSP.) and tamarack (Larix laricina (Du Roi) K. Koch) seedlings fertilized with labeled (15NH4)2SO4 or K15NO3 in a growth chamber experiment....

First-principles calculations of equilibrium nitrogen isotope fractionations among aqueous ammonium, silicate minerals and salts
Download2021-03-15
Li, Yonghui, Li, Long, Wu, Zhongqing
Nitrogen isotopes are a robust tool to study geological nitrogen cycle between Earth’s reservoirs. However, the application of nitrogen isotope system to understanding geological processes has been limited by the lack of constraints on equilibrium isotope fractionation factors between mineral and...

Integration of Subnational Endogenous Hydropower into the Global Change Analysis Model for Canada
DownloadFall 2023
Hydropower currently provides a small majority of all electricity generation in Canada. This gives the nation an early advantage for shifting toward lower-emission energy sources. Energy systems are changing rapidly to adjust to new realities regarding technologies, resource availability and...

Nitrogen isotope fractionations among gaseous and aqueous NH4+, NH3, N2, and metal-ammine complexes: Theoretical calculations and applications
Download2021-02-15
Li, Long, He, Yuyang, Zhang, Zhe, Liu, Yun
Ammonium (NH4+), ammonia (NH3) and N2 are key nitrogen species in geological nitrogen recycling. NH3 has also been proposed to play an important role in mobilizing base metals in the form of metal-ammine complexes in hydrothermal fluids. The nitrogen isotope fractionation factors among these...
