The photosynthetic performance of certain desirable plants and algae depend strongly on the exact spectrum and light/dark cycle of their illumination. Several modern and emerging technologies have the energy efficiency, and the spectral and temporal characteristics to provide optimal lighting in an amenable form factor. This project aims to compare the costs and benefits of using lasers, quantum dots, LEDs, and other competitive technologies in indoor agriculture processes and developing an optimized lighting system for indoor agriculture.
Biomass combustion, which is a growing business, is used to generate heat and power. It is a very attractive system because it provides energy at cheaper price compared to oil and gas fuels and also emits fewer pollutants into the atmosphere. As the name implies, the combustion system is fired using renewable fuels such as forest and agriculture residues. To date, the biomass combustion systems developed locally, as well as internationally, have been used mainly where there are heat demands. However, Myera Group, a Canadian company, is gradually increasing its share in the energy market.
HVdc is the preferred approach for transmission of bulk power into existing AC network from point to point and from remote generation resources because of technical advantages, including low transmission losses. Integration of HVdc grid with existing AC grid provides considerable economic benefits while throwing up challenges for effective control of both the grids at the same time.
This proposal builds on 4 years of research in the award winning HEAT (Heat Energy Assessment Technologies) project. Every year, billions of GJ of wasted heat leave millions of buildings in thousands of cities world-wide. In an effort to support urban energy efficiency, this research proposes four novel image post-processing techniques to improve/ verify the geometry, radiometry and the processing of large volumes of high-resolution airborne thermal infrared (TIR) imagery. Results are expected to enable more accurate urban waste heat mapping and refined waste heat metrics.
Biomass combustion is used to generate combined heat and power (CHP). The combustion furnace of this study (WiseWay) has been providing heat in small scales using wood pellets. The target of this project, however, is to upgrade the stove’s design (for larger scale purposes and other biomass types) and integrate it with a steam microturbine (NextGrid). The resulting system is attractive to the environment and economy because it provides heat and electricity in one package, at a cheaper price compared with oil and gas, with less pollutants emitted.
Polymer electrolyte membrane fuel cell (PEMFC) has emerged as an eminent technology to address today's growing energy crisis and environmental issues. PEMFC technology faces multiple challenges before widespread commercialization. Water transport inside a PEMFC has a significant impact on the cell performance and durability. In this internship a numerical model is implemented to study the transport phenomena inside and across the membrane of a PEMFC.
Power prices are a significant contributor to the overall risk of almost any large-scale industry. In particular, energy companies such as TransAlta who are active participants in many regional power markets have a strong interest in understanding the long-term risks they are exposed to. This project seeks to develop a model that will help TransAlta to understand some of the uncertainty in medium to long-term power prices in California, the Pacific northwest, and Alberta.
Inline coherent imaging (ICI) may be used to take real-time one dimensional measurements of laser material processes such as industrial laser welding. Multidimensional coherent imaging and measurement of the vapour capillary (or 'keyhole') created during the welding process is a critical evolution of the technology for implementation in manufacturing production addressing many needs. This project will investigate and attempt to implement multidimensional ICI in an imaging system for real world applications.
Presently, platinum (Pt) nanoparticles are required to catalyze the desired redox reactions at the anode and cathode of proton exchange membrane fuel cells (PEMFCs). The high cost of this precious metal catalyst remains a barrier to the wide spread commercialization of PEMFCs, particularly for automotive applications. In an effort to reduce the Pt loading in PEMFCs, this research project is focused on the design of novel catalysts which consist of a 1-2 monolayer “shell” of Pt on a less expensive metal which acts as a “core”.
This research is aimed at the development of new modeling and simulation algorithms of interconnected AC and DC supergrids for power flow and transient stability analyses. The efforts will be focused on the following technical areas:
