A life cycle assessment of OME (oxymethylene ether) synthesis from biomass-derived syngas as a diesel additive
Download2017-01-01
Mahbub, Nafisa, Oyedun, Adetoyese Olajire, Kumar, Amit, Oestreich, Dorian, Arnold, Ulrich, Sauer, Jörg
The life cycle energy consumption and greenhouse gas (GHG) emission performances of forest biomass-derived oxymethylene ether (OME) synthesis used as a diesel additive are analyzed in this study. OME, a new alternative liquid fuel, has great miscibility with conventional fuels like diesel. OME...

A well-to-wire life cycle assessment of Canadian shale gas for electricity generation in China
Download2016-01-01
Raj, Ratan, Ghandehariun, Samane, Kumar, Amit, Linwei, Ma
China relies heavily on coal for power generation, and the demand for coal in a country of this size makes China the world’s largest carbon dioxide emitter; hence China is pursuing greener pathways for power generation. Importing shale gas in the form of LNG from Canada is one such pathway. It...

Development of Life Cycle Water-Demand Coefficients for Coal-Based Power Generation Technologies
Download2015-01-01
This paper aims to develop benchmark coefficients for water consumption and water withdrawals over the full life cycle of coal-based power generation. This study considered not only all of the unit operations involved in the full electricity generation life cycle but also compared different...

Energy balance and greenhouse gas emissions of production and sequestration of charcoal from agricultural residues
Download2016-01-01
Thakkar, Jignesh, Kumar, Amit, Ghatora, Sonia, Canter, Christina E.
Agricultural residues (wheat/barley/oat straw) can be used to produce charcoal, which can then be either landfilled off-site or spread on the agricultural field as a means for sequestering carbon. One centralized and five portable charcoal production technologies were explored in this paper. The...

Energy consumption and greenhouse gas emissions in the recovery and extraction of crude bitumen from Canada's oil sands
Download2015-01-01
Nimana, Balwinder S., Canter, Christina E., Kumar, Amit
A model- FUNNEL-GHG-OS (FUNdamental ENgineering PrinciplEs- based ModeL for Estimation of GreenHouse Gases in the Oil Sands) was developed to estimate project-specific energy consumption and greenhouse gas emissions (GHGs) in major recovery and extraction processes in the oil sands, namely...

Energy consumption and greenhouse gas emissions in upgrading and refining of Canada’s oil sands products
Download2015-01-01
Nimana, Balwinder S., Canter, Christina E., Kumar, Amit, Oil Sands, Upgrading, Refining, SCO, Bitumen, Dilbit
A model- FUNNEL-GHG-OS (FUNdamental ENgineering PrinciplEs- based ModeL for Estimation of GreenHouse Gases in the Oil Sands)based on fundamental engineering principles was developed to estimate the specific energy consumption and greenhouse gas emissions (GHGs) for upgrading bitumen to produce...

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....

Integrated techno-economic and environmental assessments of sixty scenarios for co-firing biomass with coal and natural gas
Download2016-01-01
Agbor, Ezinwa, Oyedun, Adetoyese Olajire, Zhang, Xiaolei, Kumar, Amit
Displacement of fossil fuel-based power through biomass co-firing could reduce the greenhouse gas (GHG) emissions from fossil fuels. In this study, data-intensive techno-economic models were developed to evaluate different co-firing technologies as well as the configurations of these...
