| Frictional behaviour of wheat straw-water suspensions in vertical upward flowsThe use of biofuels helps mitigate greenhouse gas emissions. Earlier studies have shown that transporting biomass in horizontal pipelines in the form of water-based slurries significantly reduces transportation costs. The frictional behaviour of water-based chopped wheat straw slurry in a vertical pipeline has not been studied and this is the focus of this study. In situ concentrations of water-based conventional solids of medium sand, glass beads, and fine sand and straw slurry flows were determined by measuring their delivered concentrations in pseudo-homogeneous regimes for prepared concentrations of 1–6% (dry volume of conventional solids) and 5–25% (saturated mass of straw), respectively. Two grades of sand and glass beads with mean particle diameters of 0.103, 0.447, and 0.5 mm, respectively, and straw with a nominal particle length of 19.2 mm were utilised. The delivered concentrations for the straw slurries and fine sand were close to their corresponding prepared concentrations and were homogeneous. There was a large discrepancy between prepared and delivered concentrations for the medium-sized sand and glass beads slurries. The pressure drop of straw slurries over the range of velocities of 0.5–4.2 m s−1 and mass concentrations of 5–25% through the vertical pipe showed a maximum drag reduction of 19% at a concentration of 25% (mass) and at a 3.5 m s−1 velocity. For concentrations of 5–20% (mass), the straw slurries showed drag-reducing capabilities in the mixed and turbulent flow regions for various velocities that were different from horizontal flows.T01-P05 University of Alberta | Publication | 2021-10-18 | Kashif Javed, Mahdi Vaezi, Vinoj Kurian, Kumar, A. |

| The development of empirical correlations to understand the frictional behavior of aqueous biomass slurry flows in vertical pipesLarge-scale biofuel production at levels equivalent to conventional oil refineries using long-distance pipeline hydro-transport of biomass can be a cleaner alternative to fossil fuels when it comes to economics and traffic congestion associated with the overland transportation of biomass. The transport of aqueous slurries of several saturated mass concentrations (5%-40%) and four-particle sizes (from <3.2-19.2 mm) of two types of agricultural residue biomass (ARB) feedstock (corn stover and wheat straw) was studied through a vertical test section of a 29 m long, 50 mm diameter closed circuit pipeline facility, and frictional pressure drops were recorded at different flow rates (0.5-4.3 m s-1). A framework was developed in RStudio (4.0.5) to analyze the experimentally obtained frictional pressure drops of biomass slurries through a multiple linear regression approach using a backward elimination method and Akaike information criterion. An empirical model was proposed to predict slurry frictional pressure drop in terms of slurry velocity, slurry solid mass concentration, particle aspect ratio, and feedstock type. The model satisfactorily predicted the frictional pressure drops of both feedstocks of biomass-water slurry flows through pipes within a 95% confidence interval. The correlations introduced for onset velocities of drag reduction in terms of slurry solid mass concentrations seemed helpful to interpret the transition points of the corresponding slurries in vertical upward flows through pipes. The empirical correlation developed in this research could help select biomass slurry pumps and pipe dimensions when designing a typical long distance pipeline network for biofuel production at the commercial level.T01-P05 University of Alberta | Publication | 2023-06-05 | |

| Experimental study on two-phase (solid-liquid) flows of ground wheat straw in inclined pipes Long-distance pipeline hydro-transport of lignocellulosic biomass for industrial-scale biofuel production at levels comparable to conventional oil refineries presents an economically and logistically viable alternative to fossil fuels. There is limited understanding of the behavior of the transportation of agricultural biomass slurries in an inclined pipeline. This research is focused on a laboratory-scale investigation of 6.4 mm nominal particle length (d50 = 4.85 mm) knife-milled wheat straw-water suspensions' uphill and downhill flows for a range of pipe inclination and saturated mass concentrations. The range of pipe inclination and saturated mass concentration was -7° to +21° and 5%-30%, respectively. The inclined test section was 29 m long with a 50 mm inside diameter of a closed pipeline loop. The accuracy of the measurements was verified by calibrating the inclined pipe section with fine sand (d50 = 0.103 mm)-aqueous slurries and comparing the results with established correlations. Most wheat straw-aqueous suspensions in the inclined flows showed the characteristics of the plug flow and the transition flow regions together for saturated mass concentration, Cm = 5%-30% and the entire flow range (0.5-4.7 m s-1), with a clear dependence of both the onset velocity of drag reduction (vOD) and drag reduction (%DR) on the pipe inclination as well as the slurry concentration and the critical concentration of maximum drag reduction (Cm)cr on a specific range of suspension velocity. Because of the accelerating effect of gravity, downhill slurry flows had the lowest vOD and the highest %DR at every Cm and pipe inclination with a maximum drag reduction of 25.53% at vm = 4.5 m s-1 and Cm = 25%. Uphill flows demonstrated some nonmonotonic changes in vOD and %DR, which need more experimental data for us to reach a firm conclusion. The research outcomes could help design and operate a long-distance integrated pipeline network for biomass transportation to produce biofuels on a large scale.

| Comparison of frictional behaviour and techno-economics of agricultural residue biomass in ascending and descending pipesThis study focuses on the techno-economic assessment of the hydro-transport of chopped agricultural and forest residue biomass by pipeline over a long distance. This could be the most sustainable and economical mode of delivering biomass for the production of biofuels on commercial scale (on par with fossil fuels). Horizontal pipeline loop arrangement has been studies earlier. However, techno-economic assessment of inclined pipeline transport of biomass slurries have not been studied earlier. This study aims at addressing this gap. A long-distance pipeline network's size and cost must be accurately estimated by comprehending and measuring the frictional behaviour and rheological characteristics of various types and sizes of materials through pipe sections at various inclinations. The main objective of the current study is to analyse the frictional behaviour of 6.4 mm particle size of wheat straw aqueous slurries as they pass through a 7.3 m long inclined pipe segment with a 50 mm diameter that is a part of a 29 m long closed-circuit pipeline facility. It will also be examined how frictional pressure drops of biomass-water slurries are impacted by pipe inclinations (both ascending and descending) in relation to the horizontal axis, slurry solid concentration, and slurry velocities. Using the findings of this study, a detailed techno-economical model for long-distance pipelines from farms to large biorefineries will be developed to estimate the cost of delivery of biomass slurries on a large scale. This information developed in this study will help in development of biorefineries on a commercial scale.

| Analysis of Canada’s water use: Tracing water flow from source to end useThis study provides estimates for disaggregated water use by regional subsectors and uses Sankey diagrams to depict the water flow from the intake to consumption and discharge. The study uses a bottom-up method in the oil and gas and hydropower sectors and top-down methods in the residential, commercial and institutional, manufacturing, mining, agricultural, and power sectors. Surface and groundwater are considered separately. Water use in the year 2017 was analyzed for British Columbia, Alberta, Saskatchewan, Manitoba, Ontario, Quebec, the Atlantic Provinces, and the Territories. Water-use intensities were also calculated by region and sector. A total of 40 billion m3 of water use is traced from source to either discharge or consumption. New disaggregated data is developed provincially and by sector for oil and gas, mining, and power generation. Water use in the oil and gas sector was disaggregated into 5 subsectors, with oil sands surface mining in Alberta as the largest consumer with 138 million m3 of water consumed. Hydropower was estimated to consume the most water out of all sectors, with 3393 million m3 of water consumed. Alberta was also found to have the largest consumptive water use per capita.T13-P01 University of Alberta | Publication | 2021-11-09 | "Nikhil Agrawal ", Thomas Edward Lamont Patrick, Matthew Davis, "Ahiduzzaman M ", Kumar, A. |

| Technology-based Options for Achieving Net-zero GHG Emissions in CanadaWe have developed a framework for accounting and assessing technology-specific measures toward achieving net-zero GHG emissions within a multi-regional multi-sectoral economy based on a bottom-up energy model featuring high technological detail. This framework allows for system-wide effects and costs to be assessed incrementally and can facilitate regional decarbonization policy development. This framework indicates the gaps between currently available technologies and GHG emissions goals; other approaches may blur the line between current and aspirational technologies.
We used this framework to perform a case study for Canada, where we established a portfolio of 184 measures based on a thorough review, and, after categorizing them according to type and technological readiness, evaluated their economic and environmental performance. We compared the effects of these measures to static reference and business-as-usual scenarios reflective of current policy. Together, the assessed measures represent an extensive portfolio of commercially available opportunities for energy efficiency improvement, fuel-switching, and carbon capture and storage. The results show the magnitude of the gaps between national GHG reduction ambitions and currently available solutions and highlight the need for more transparent and credible approaches to economy-wide decarbonization assessment.

| Evaluation of using Alberta hydrogen for clean-firm power in decarbonized power gridsWe evaluated the role that hydrogen can play in achieving a decarbonized power grid. Seventy-two scenarios were explored, and we assessed the greenhouse gas reduction potential of these scenarios, as well as their costs. Our research demonstrates that hydrogen for clean, firm power can effectively provide clean electricity and reduce emissions. However, the source of hydrogen is critical to achieving GHG reductions in the province. We also found that using hydrogen for clean, firm power can create economic benefits, such as investment in infrastructure and jobs. However, this could lead to unwanted increases in electricity prices. Blue hydrogen-based power is not economical in a grid-like we have today, but it can be a competitive option in a nearly decarbonized grid, but only if fueled by ATR with CCS. Finally, hydrogen in the power sector is just one option to reduce emissions. Out of the options assessed in our group, other options are available at lower costs that provide deeper emission cuts, and these should be compared before making decisions.T13-P01 University of Alberta | Activity | 2023-04-25 | |
| A strategy assessment to decarbonize road transport in AlbertaThe objective of this work is to contribute to finding answers to key questions for the decarbonization of road transport in Alberta. These questions are: 1) What is the GHG mitigation potential of hydrogen vehicles? 2) What’s the market share of hydrogen vehicles in different sectors? 3) What is the impact of policies like carbon price, zero-emission vehicles (ZEVs) sales mandate, and incentivization? Our study found that the ZEV sales mandate is the most effective way of transitioning the road transportation sector to ZEVs. The market shares of battery electric vehicles (BEVs) were found to be highest in 2050. Carbon price and incentivization do not have a significant effect on the cost or market share of ZEVs and in decreasing energy demand and GHG emissions. The emission factors of H2-FCEV ATR with 91% carbon capture are lowest at lower carbon prices. The carbon price scenarios have the most significant impact of all the scenarios on social costs.T13-P04 University of Alberta | Activity | 2023-04-26 | |
| Development of a framework to assess the greenhouse gas mitigation potential from the adoption of low-carbon road vehicles in a hydrocarbon-rich regionThis study developed a novel assessment framework to analyze long-term energy transition in the road transport sector in which various technology options, market shares, policy measures, costs, and greenhouse gas emissions are considered in a single framework analysis. A data-intensive model was developed with the Low Emissions Analysis Platform (LEAP) and used to analyze policy scenarios up to 2050 for Alberta, Canada, a hydrocarbon-rich province with an emission-intensive energy sector. Three key policy measures – carbon pricing, zero-emission vehicle sales mandate, and incentivization – were analyzed in nine individual and combined policy scenarios. The transition to both hydrogen fuel cell electric vehicles and battery electric vehicles was assessed for
all vehicle categories. Each fuel’s full energy supply chain was modeled, including resource extraction, conversion, transmission and distribution, and fuelling, allowing for final and primary energy analysis. The findings show that carbon price and zero-emission vehicle incentives do not effectively lower greenhouse gas emissions on their own; zero-emission vehicle mandates are needed to transition the sector to a low-carbon energy system. The system-wide greenhouse gas emission footprints of hydrogen and battery electric vehicles are significantly below conventional vehicles in all cases. Scenarios biased towards battery electric vehicles had the most favorable results. The greenhouse gas emission footprint of hydrogen vehicles supplied by auto-thermal
reforming with 91% carbon capture was lower than for battery electric vehicles powered by a primarily natural gas-based power grid. The findings on the effectiveness of carbon prices, incentives, and vehicle mandates should be considered by government policymakers aiming to reduce greenhouse gas emissions, infrastructure planners, and other energy stakeholders.T13-P04 University of Alberta | Publication | 2024-01-12 | |

| Development of a framework for the assessment of the market penetration of novel in situ bitumen extraction technologiesGreenhouse gas (GHG) mitigation opportunities from emerging in situ mining technologies in oil sands production can play a role in reducing global warming. There is limited research on quantitative assessments of the penetration of emerging oil sands technology in the energy sector. This study addresses this gap by developing a novel framework (MAPL-OET) to assess the market penetration of emerging oil sand extraction technologies. The framework is robust and data-intensive as it combines diffusion models, econometrics models, cost models, and energy-economy equilibrium models. The combined model evaluates the adoption of new energy technologies resulting from carbon price measures and other economic factors, as well as the GHG mitigation potential in the oil sands sector.

| Techno-economic assessment of titanium dioxide nanorod-based perovskite solar cells: from lab-scale to large-scale manufacturing Perovskite solar cells (PSCs) have shown remarkable progress in recent years. Different materials and structures have been developed to improve the photoconversion efficiency and operational stability of PSCs. However, the economic and technical impacts of materials and design choice on the large-scale deployment are not well addressed in the literature. In this research, a pathway for producing titanium dioxide (TiO2) nanorod-based perovskite solar modules was established and their manufacturing cost was estimated through the development of data-intensive, bottom-up techno-economic models. Material, utilities, and equipment requirements from available laboratory data to a mass production annual capacity of up to 21 MW were estimated through the development of scale factors. The minimum sustainable price and levelized cost of electricity were calculated. The direct manufacturing cost of the reference PSC module was estimated at $80.23/m2 and $0.73/W with a production capacity of 3.5 MWp. These costs decline to $47.15/m2 and $0.43/W at 21 MW production capacity. Material costs dominate the overall costs, fluorine-doped tin oxide glass being the most expensive material. The perovskite solar cell panels, when installed in residential homes in Alberta, Canada, were calculated to have a competitive levelized cost of electricity ranging from 7 to 17 cents per kWh. However, the cost was found to be extremely sensitive to the module efficiency, lifetime, and the solar insolation at the location of installation.T12-P02, T13-P04 University of Alberta | Publication | 2021-06-18 | |

Two pathways were considered. In pathway I, extracted bitumen is sent to Edmonton for upgrading and pipelined to the Westridge terminal near Vancouver, then shipped to a port in China. In pathway II, extracted bitumen is mixed with diluent, directly pipelined to the Westridge terminal, and shipped to China. The results from both the pipeline and the shipping models suggest that pathway I has better GHG emissions than pathway II on a per-barrel basis.

| Developing a framework to assess the long-term adoption of renewable energy technologies in the electric power sector: the effects of carbon price and economic incentivesLarge-scale deployment of renewable energy can play an immense role in transforming the global energy system and mitigating emissions. This paper describes the development of a novel framework called MArket Penetration ModeLing of Renewable Energy Technologies in Electric Power Sector (MAPLET-PS). MAPLET-PS assesses the impacts of policy measures such as carbon price and financial incentives on the adoption of renewable energy technologies. The framework was used to develop a case study for the electric power sector ofAlberta, a fossil-dominated province in Western Canada. The results show that implementing a carbon price on
fossil fuel electric power sources and incentives for renewable energy, along with the phase-out of coal-firedelectricity generation, can mitigate 29% of Alberta’s electricity sector 2020 GHG emissions by 2050 and reduce GHG emissions from 46.5 Mt of CO2 eq. in 2020 to 23.6 and 29.1 Mt of CO2 eq. per year in 2030 and2050, respectively, in Alberta. Moreover, these changes can increase the share of renewable energies from 12.5% in 2018 to 30% in 2050. These rates can be achieved by implementing a carbon price along with a 1000 $ incentive per kW new capacity development and 70 $ incentive per MWh electric power generation from renewable sources, from 2021 to 2025, primarily from wind turbines.T13-C01 University of Alberta | Publication | 2021-09-21 | Saeidreza Radpour, Eskinder Gemechu, "Ahiduzzaman M ", Kumar, A. |

| Developing a framework to evaluate the life cycle energy and greenhouse gas emissions of space heating systems using zeolite 13X as an adsorbent materialThe wide use of fossil-based space heating systems results in significant greenhouse gas (GHG) emissions. Using solar energy for space heating can help reduce GHG emissions. However, solar energy generation is intermittent and needs to be stored for continuous supply. The zeolite 13× adsorbent heat storage system for space heating is a promising alternative. There is limited research on the life cycle GHG footprint of this type of adsorbent storage system. In this study, we developed a framework that integrates engineering design with life cycle assessment to evaluate the energy and emission performances of a zeolite 13×-based heating system charged by a solar air collector. A simulation model was developed for this adsorbent storage system. The life cycle GHG emissions of the residential heating system are estimated to be 0.1160 kg CO2 eq per kWh of the heat delivered over a 20-year lifetime. The operational phase contributes 74 % of the overall emissions because of the energy required by the humidifiers. The material production stage accounts for 25 %, mainly attributed to the upstream emissions in manufacturing photovoltaic thermal (PVT) air solar systems. The net energy ratio (NER), the ratio of energy output to fossil energy input, is 2.9. The continuous days without sunlight, the adsorbent vessel length-to-diameter ratio (L/D), and the pellet diameter of the zeolite 13× storage appear to be the parameters most sensitive to both emissions and NER. The uncertainty analysis shows emissions and NERs of the space heating system in the range of 97.2–152.3 g CO2 eq/kWh and 2.4–3.0, respectively. Compared with other alternative heating systems, the adsorbent system has better GHG performance. The research highlights the importance of selecting a suitable space heating system given the high influence of operational energy on the life cycle emissions and the range of electricity generation emissions in different provinces.T13-P04 University of Alberta | Publication | 2023-11-02 | T V Tran, Eskinder Gemechu, Olufemi Oni, "Carrier Y ", "Tezel H ", Kumar, A. |
| Life cycle assessment of earth-abundant photocatalysts for enhanced photocatalytic hydrogen productionHydrogen (H2) can play a critical role in global greenhouse gas (GHG) mitigation. Photocatalytic water splitting using solar radiation is a promising H2 technology. Titanium dioxide (TiO2) and carbon nitride (g–C3N4)–based photocatalysts are the most widely used photocatalytic materials because of their activity and abundance. Several attempts have been made to improve the photocatalytic performance of these materials in terms of their activity level, life span, response to visible radiation, and stability. However, the environmental impacts of these modifications are often not included in existing studies. This research, therefore, develops a cradle-to-grave life cycle assessment (LCA) framework to evaluate and compare the GHG footprints of four alternative pathways: TiO2 nanorods and fluorine-doped carbon nitride quantum dots embedded with TiO2 (CNF: TNR/TiO2), g-C3N4, and g-C3N4/BiOI composite. Unlike most studies that focus only on certain stages such as laboratory-scale photocatalytic fabrication, this study includes utility-scale cell production, assembly, operation, and end of life to give a more accurate and precise environmental performance estimation. The results show that g-C3N4/BiOI has the lowest GHG footprint (0.38 kg CO2 eq per kg of H2) and CNF: TNR/TiO2 has the lowest energy payback time (0.4 years). In every pathway, energy use in material extraction processes makes up the largest GHG contribution, between 83% and 89%. Sensitivity and uncertainty analyses were conducted under the impact of various input parameters on the life cycle GHG emissions of hydrogen production. Photocatalytic water splitting is highly feasible for adaptation as a mainstream hydrogen production pathway in the future.

| The development of a novel framework based on a review of market penetration models for energy technologies,The aim of this paper is to review and evaluate models used to assess the market penetration of energy technologies. While there are different models and tools, choosing the appropriate approach for a particular application is very challenging. In this paper, each model is reviewed and discussed extensively and a hierarchy diagram is developed to help choose a model. Market penetration models based on subjective estimation and market survey could be individual-dependent and not reliable for long-term forecasts. Cost estimation, diffusion, and econometric models offer more reliable results both for short- and long-term forecasts. Based on the review, a new combined model was developed and applied to a case study. The combined use of different market penetration models offers more accurate and robust results, as demonstrated in the case study.

| Assessment of the solvent-electromagnetic heating-based bitumen extraction technology through techno-economic modellingThe steam-assisted gravity drainage is a
widely used extraction method for bitumen in a deep reservoir, however, it is greenhouse gas (GHG) emission intensive because of high fossil fuel consumption. There is a lot of interest in bitumen extraction technologies with a low GHG emissions footprint. Solvent-electromagnetic Heating (SEH) is an emerging technology that can lower GHG emissions in oil sands extraction. SEH uses an electromagnetic device and solvent to preheat and mobilize emulsion from the reservoir. SEH
eliminates the dependence on condensation heat and therefore the strict requirement of solvent purity. However, few studies have explored its techno-economic feasibility. Unlike studies found in the literature, this study presents a detailed techno-economic assessment, where plant size,
operating and economic parameters are evaluated to measure their impacts on the economics of SEH technology.T13-M01 University of Alberta | Publication | 2022-03-21 | |

| A review of Canadian wood conversion technologies for the production of fuels and chemicalsCanada has 347 million ha of forest cover, contributing to the potential large availability of wood-based resources. Although Canada's forest sector contributed $23.7 billion to the national nominal gross domestic product (GDP) in 2019, the GDP contribution of the wood product manufacturing subsector shrank by 6%. To reposition the Canadian forest industry, new forest management practices and wood-based conversion technologies should be applied. In this context, the use of woody biomass in biorefineries to produce clean energy, fuels, and chemicals is becoming increasingly significant. There is a need to understand the current status and challenges of the wood-based biomass conversion technologies that have been and are being developed in Canada. This information will help decision-makers in formulating and implementing forest sector-related policies for a sustainable bioeconomy in Canada. This study is focused on a review of Canadian woody biomass conversion technologies. Our critical review identified considerable potential biomass conversion technologies specialized for woody feedstock, all in the Canadian setting. We focused on the prospects of revitalizing Canada's pulp and paper industry through the integration of pre-treatment processes and biochemical technologies. The thermochemical conversion pathway was identified as the dominant route for woody feedstock valorization. The review also identified pathways with the potential to diversify the existing product mix that generates products from wood streams, such as chemicals and biomaterials. Most of the biochemical and thermochemical research done in institutional and multi-institutional research collaborations from laboratory scale to industrial scale will boost the chances of the commercialization of a wood-based biorefinery in Canada.T13-P04 University of Alberta | Publication | 2023-07-06 | "Sreekumar A ", Vinoj Kurian, Kumar, A., Omex Mohan, "Mvolo C " |

| Investigation into the drag reduction behavior during pipeline hydro-transportation of forestry residues The potential of utilizing forestry residues for bioenergy is an attractive option for curbing greenhouse gas emissions and providing new opportunities for the forestry sector. However, the feedstock transportation using trucks to bioenergy facilities is challenging due to the remoteness of feedstock supply locations and the associated high cost. A viable alternative is to use pipelines to transport wood residues as slurry to the end conversion facilities. Even though wood chip slurry transportation has been previously studied with larger particle sizes, the mechanisms of slurry behavior with smaller particles must be further explored. The techno-economic attractiveness will be substantially improved if the forestry residue slurries behave similarly to agricultural residue slurries and show drag reduction behavior. Therefore, the primary goal of this research is to investigate the mechanisms of forestry residue slurry transport using a 2-inch pipeline system and to study the effect of bulk velocity, slurry concentration, and particle characteristics on slurry pressure drop. We measured pressure gradients for wood particle sizes ranging from 1.3 to 3.2 mm with saturated mass concentrations ranging from 5% to 35% and bulk velocities ranging from 0.5 to 5.0 m/s. The results show that drag reduction behavior exists in wood residue slurries with small particle sizes (<2.6 mm) and aspect ratios (4-6). Pressure drop was reduced by 22% when 1.3 mm residues were pumped at a bulk velocity of 3.4 m/s and a saturated mass concentration of 25% compared to water. The relationships between the slurry pressure drop and saturated mass concentration were estimated and used to determine the lower and higher limiting requirements for the drag-reducing regimes in the flow of wood slurry for a given particle size and bulk velocity. The findings of this study will be critical in determining the techno-economic feasibility of pipeline hydro-transportation of forest residues.T01-P05 University of Alberta | Activity | 2024-04-05 | |
| Pelletization of Three Municipal Solid Waste Streams: Digestate, Source Separated Organics and Refuse Derived Fuel for Use in a BiorefineryWaste-to-energy conversion is one promising approach for sustainable waste management. Densified pelletized biomass meets the requirements to be used in such conversion processes. This study focuses on the thermo-chemical characterization, feasibility of pelletization, the effect of particle size and moisture content of three different waste streams: Source Separated Organics (SSO), Refuse Derived Fuel (RDF), and Digestate from the City of Edmonton. Three different milling sizes of 4, 8, and 12 mm, having a moisture content (MC) of 10 and 15% were processed through a die size of 6 mm. Both RDF and SSO could be pelletized. The produced RDF pellets had a calorific value of 21.49 MJ/Kg; the SSO pellets presented a variation between the winter and spring-summer seasons, having an HHV of 19.47 MJ/Kg in winter and 13.88MJ/Kg in spring-summer; this variation is linked with changes in the feedstock composition. The Digestate showed the lowest energetic content with 10.07 MJ/Kg. The ground RDF and SSO particle size directly affects the specific energy consumption and pelletization temperature but has an inverse relation with the process throughput. The moisture content directly affects the pelletization energy requirement for SSO, but the relation is inverse for RDF. The quality of the produced pellets was assessed; for the RDF, the maximum durability achieved was 98.23 %, while for SSO was 97.4 %; The maximum bulk density reached was 594 Kg/m3 for RDF and 730 Kg/m3 for SSO. The optimal pelletization variables were identified for potential scale-up and feedstock production in future thermochemical conversion research. The results of the study is critical for the utilization of the various components of MSW for the production of fuels and chemicals in a biorefinery and contribute to the concept of circular economy.T01-P05 | Activity | 2023-07-09 | Benjamin Mauricio Martinez Castellanos, Omex Mohan, Vinoj Kurian |
| Development of techno-economic models for assessment of solvent-based bitumen extraction technologyThis study conducts a holistic comparative cost and life cycle GHG emissions’ footprint assessment of three natural gas-based blue hydrogen production technologies – steam
methane reforming (SMR), autothermal reforming (ATR), and natural gas decomposition (NGD) to address these research gaps. A hydrogen production plant capacity of 607 tonnes
per day was considered. For SMR, based on the percentage of carbon capture and capture points, we considered two scenarios, SMR-52% (indicates 52% carbon capture) and SMR-85%
(indicates 85% carbon capture). A scale factor was developed for each technology to understand the hydrogen production cost with a change in production plant size. The results
indicate that when uncertainty is considered, SMR-52% and ATR are economically preferable to NGD and SMR-85%.
SMR-52% could outperform ATR-CCS when the natural gas price decreases and the rate of return increases. SMR-85% is the least attractive pathway; however, it could outperform
NGD economically when CO2 transportation cost and natural gas price decrease. Hydrogen storage cost significantly impacts the hydrogen production cost. SMR-52%, SMR-85%, ATR-CCS,
and NGD-CCS have scale factors of 0.67, 0.68, 0.54, and 0.65, respectively. The hydrogen cost variation with capacity shows that operating SMR-52% and ATR-CCS above hydrogen
capacity of 200 tonnes/day is economically attractive. Blue hydrogen from autothermal reforming has the lowest life cycle GHG emissions of 3.91 kgCO2eq/kg H2, followed by
blue hydrogen from NGD (4.54 kgCO2eq/kg H2), SMR-85% (6.66 kgCO2eq/kg H2), and SMR-52% (8.20 kgCO2eq/kg H2). The findings of this study are useful for decision-making at

| Comparative assessment of blue hydrogen from steam methane reforming, autothermal reforming, and natural gas decomposition technologies for natural gas-producing regionsInterest in blue hydrogen production technologies is growing. Some researchers have evaluated the environmental and/or economic feasibility of producing blue hydrogen, but a holistic assessment is still needed. Many aspects of hydrogen production have not been investigated. There is very limited information in the literature on the impact of plant size on production and the extent of carbon capture on the cost and life cycle greenhouse gas (GHG) emissions of blue hydrogen production through various production pathways. Detailed uncertainty and sensitivity analyses have not been included in most of the earlier studies. This study conducts a holistic comparative cost and life cycle GHG emissions’ footprint assessment of three natural gas-based blue hydrogen production technologies – steam methane reforming (SMR), autothermal reforming (ATR), and natural gas decomposition (NGD) to address these research gaps. A hydrogen production plant capacity of 607 tonnes per day was considered. For SMR, based on the percentage of carbon capture and capture points, we considered two scenarios, SMR-52% (indicates 52% carbon capture) and SMR-85% (indicates 85% carbon capture). A scale factor was developed for each technology to understand the hydrogen production cost with a change in production plant size. Hydrogen cost is 1.22, 1.23, 2.12, 1.69, 2.36, 1.66, and 2.55 $/kg H2 for SMR, ATR, NGD, SMR-52%, SMR-85%, ATR with carbon capture and sequestration (ATR-CCS), and NGD with carbon capture and sequestration (NGD-CCS), respectively. The results indicate that when uncertainty is considered, SMR-52% and ATR are economically preferable to NGD and SMR-85%. SMR-52% could outperform ATR-CCS when the natural gas price decreases and the rate of return increases. SMR-85% is the least attractive pathway; however, it could outperform NGD economically when CO2 transportation cost and natural gas price decrease.

| Synergistic effect of water and co-solvents on the hydrothermal liquefaction of agricultural biomass to produce heavy oilHydrothermal Liquefaction (HTL) was performed on Alberta’s agricultural biomass, corn stover and wheat straw, at an operating temperature of 300°C, initial reactor pressure of 600 psi and zero min retention time. Effects of adding Co-solvents (Methanol, Ethanol, and 2-Propanol) on yield and quality of heavy oil has been studied. 2-Propanol exhibited to be a promising Co-solvent that has improved the quality of heavy oil. HTL of corn stover using water-2-propanol mixture produced heavy oil having oxygen content of 18.8 wt.%, Higher Heating Value (HHV) of 32.0 MJ/kg and Total Acid Number (TAN) value of 81.74 mg KOH/g oil. HTL of wheat straw using water-2-propanol mixture produced heavy oil showing an oxygen content of 17.99 wt.% and HHV of 32.86 MJ/kg.T01-P05 University of Alberta | Publication | 2022-01-06 | |
| A Review of Hydrothermal Liquefaction of Biomass for Biofuels Production with a Special Focus on the Effect of Process Parameters, Co-Solvents, and Extraction SolventsHydrothermal liquefaction is one of the common thermochemical conversion methods
adapted to convert high-water content biomass feedstocks to biofuels and many other valuable
industrial chemicals. The hydrothermal process is broadly classified into carbonization, liquefaction,
and gasification with hydrothermal liquefaction conducted in the intermediate temperature range of
250–374 ◦C and pressure of 4–25 MPa. Due to the ease of adaptability, there has been considerable
research into the process on using various types of biomass feedstocks. Over the years, various
solvents and co-solvents have been used as mediums of conversion, to promote easy decomposition of the lignocellulosic components in biomass. The product separation process, to obtain the finalproducts, typically involves multiple extraction and evaporation steps, which greatly depend on the type of extractive solvents and process parameters. In general, the main aim of the hydrothermalprocess is to produce a primary product, such as bio-oil, biochar, gases, or industrial chemicals,such as adhesives, benzene, toluene, and xylene. All of the secondary products become part ofthe side streams. The optimum process parameters are obtained to improve the yield and quality of the primary products. A great deal of the process depends on understanding the underlined reaction chemistry during the process. Therefore, this article reviews the major works conducted in the field of hydrothermal liquefaction in order to understand the mechanism of lignocellulosic conversion, describing the concept of a batch and a continuous process with the most recent state-of-art technologies in the field. Further, the article provides detailed insight into the effects of various process parameters, co-solvents, and extraction solvents, and their effects on the products’ yield and quality. It also provides information about possible applications of products obtained through liquefaction. Lastly, it addresses gaps in research and provides suggestions for future studies.T01-P05 University of Alberta | Publication | 2021-08-11 | |

| A comprehensive assessment of the integration of solvent and steam for the extraction of bitumen through the development of novel process modelsSolvent-steam bitumen extraction technology has the potential to reduce energy consumption and greenhouse gas (GHG) emissions. It is based on gravity drainage, wherein a steam and vaporized solvent mixture is used to extract bitumen from a reservoir. This can reduce the environmental impact compared with processes that use only steam for bitumen extraction [i.e., steam-assisted gravity drainage (SAGD)]. No techno-economic analysis of solvent-steam extraction has been made available in the public domain. In this study, a process simulation model was developed to assess costs. A capacity of 25,000 B/D of bitumen was considered with hexane as the solvent. Sensitivity and uncertainty analyses were conducted to assess how the supply cost of bitumen produced with diluent (dilbit) changes with changes in input parameters. The supply cost for the base case scenario is 55.5 CAD/bbl at a 10% internal rate of return (IRR). The scale factor was estimated to be 0.80, which suggests that oil production will be economically viable on a large scale. Capital cost, solvent price, and transportation and blending cost affect the supply cost. The most probable supply cost range is 53.0–65.4 CAD/bbl at a 90% confidence interval. The results also indicate that dilbit supply costs from the solvent-steam process are economically attractive compared with the current oil price.T13-P04 University of Alberta | Publication | 2024-01-19 | |
| Planning for net-zero GHG emissions by 2050: Moving from technical feasibility assessments to actionable analysisResearchers with the Intergovernmental Panel on Climate Change (IPCC) predict that the net flux of anthropogenic greenhouse gas (GHG) emissions must reach zero by 2050 to limit global warming to 1.5°C within this century. This target requires that all GHG emissions resulting from human activity are offset by equal levels of natural or technological carbon uptake, meaning that action towards net-zero GHG emissions may involve measures aiming to minimize GHG sources or maximize GHG sinks. Achieving net-zero greenhouse gas (GHG) emissions may only be possible through the rapid deployment of new technologies at an unprecedented rate, requiring policymakers to develop creative policy instruments to facilitate collaborative action across sector boundaries. This research describes a novel approach to planning for and assessing action towards net-zero GHG emissions based on bottom-up, accounting-based energy modelling techniques.
The first part of this research develops a framework for assessing the contribution potential of energy-efficiency measures towards economy-wide net-zero emission targets. The framework uses a bottom-up energy model spanning the agriculture, cement, chemicals, commercial and institutional, iron and steel, oil extraction, petroleum refining, and residential sectors, together accounting for over 75% of annual energy demand in the case study region of Alberta, Canada. 81 energy-efficiency improvements were identified for these sectors which, by 2050, may mitigate 8% of regional annual GHG emissions relative to a baseline in which shares and efficiencies of existing technologies are held constant. Considering the interaction effects between simultaneously applied measures, measures representing 80% of the identified cumulative mitigation potential may be implemented at negative cost. The assessed energy-efficiency measures represent cost-effective and readily deployable GHG mitigation strategies for most major economic sectors, but together only account for a small fraction of the GHG mitigation required for complete energy system decarbonization in the assessed region. This framework offers value to policymakers developing actionable policy and milestone targets towards long-term emissions-reduction goals.
This framework was expanded to assess technology-specific measures toward achieving net-zero GHG emissions within a multi-regional multi-sectoral economy, where the effects, costs, and benefits of various GHG mitigation measures could be assessed incrementally. A portfolio of 184 measures was developed. Measures were categorized according to practical type and technological readiness and their maximum technical GHG mitigation potential was evaluated. These measures are applicable in the cement, chemicals, commercial and institutional, iron and steel, oil sands, petroleum refining, pulp and paper, residential, and transportation sectors. The effects of these measures were compared to a static reference scenario and a business-as-usual scenario reflecting current policy. Together, the assessed measures represent an extensive portfolio of commercially available opportunities for energy efficiency improvement, fuel switching, and carbon capture and storage. Under current policy, these measures may mitigate 33% of baseline GHG emissions by 2050 and represent significant economic cost savings. If implemented to their maximum extent, they may reduce baseline GHG emissions by 50% by 2050 at additional economic costs. The results indicate that there is a clear gap between national GHG reduction ambitions and available solutions and highlight the need for more transparent and specific energy systems models for decarbonization assessment.
This research ultimately highlights the gap between currently available GHG reduction measures and complete decarbonization; achieving net-zero GHG emissions will only be possible through a complete transformation of entire energy systems and economies. Existing assessment frameworks that represent net-zero as a system-wide constraint and model hypothetical technologies alongside proven measures often fail to communicate the magnitude of change implied by this target.

| A parametric study through the modeling of hydrothermal gasification for hydrogen production from algal biomassHydrothermal gasification (HTG) is applicable to high moisture content biomass feedstock such as wet microalgae. The key interests of this thermochemical processing are its ability to use whole algae instead of simply lipid extracts and to use a wide range of algal feedstocks. It employs water in the form of a reaction medium to disintegrate biomass into hydrogen gas. The products' composition and yields are a function of process parameters, namely feed concentration, pressure, and temperature. There is very limited literature available on model development to understand the impacts of various input parameters on the products of HTG. This study presents the development of a detailed process model for HTG and the illustration of process parameters on the gas product yields. The approach includes developing the system model, identifying the key process parameters in the reactor setup that affect syngas yield, and understanding the overall process in terms of final product yield. A simulation of hydrothermal gasification based on thermodynamic equilibrium is studied. Based on the developed process model about 52.1 t/day of hydrogen can be produced from 500 t/day of wet algal biomass. This shows the potential of large-scale hydrogen production through this process for the hydrogen economy. The results from this study could be used by the gas processing industry and policymakers to determine the most feasible means of converting biomass-based resources into gaseous fuels.T01-P05 University of Alberta | Publication | 2021-04-01 | |
