Radiolysis of water produces hydrogen, oxygen and hydrogen peroxide, which can be deleterious to system components. The radiolytic production of these species can be mitigated through appropriate chemical dosing with small amounts of dissolved hydrogen or oxygen-scavenging chemicals such as hydrazine. Corrosion of carbon steel components in the End Shield Cooling system of a CANDU reactor consumes oxygen, which can also keep the system in a state of net radiolytic suppression.
Currently, developing 3D pipeline GIS (Geographical Information System) with 3D data interoperability is not only highly required by pipeline industry but also essential for building 3D SDI (Spatial Data Infrastructure). This project proposes a novel approach to develop a new 3D GIS Web Services framework and components that is suitable for 3D Pipeline GIS and 3D SDI.
Increasing global energy demand coupled with efforts to reduce our carbon emission has pushed for improved energy efficiency in many areas. One area in need of improvement is residential and commercial buildings. Specifically, the demand-side energy management of commercial buildings can be improved significantly with improved control. With the addition of on-site renewable energy generation such as Photo-Voltaic and energy storage, a large commercial building can be optimally controlled to provide reliable, stable power while maintaining minimal wasted energy.
This proposal builds on 5 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 faster and more accurate urban waste heat mapping and refined waste heat metrics.
SaskEnergy developed an in-situ remediation program using a soil vapour extraction (SVE) system to facilitate recovery of petroleum hydrocarbons at the Cantuar Site. One of main problems associated with this program is the deficiency in the knowledge of process control based on the fate and transport of contaminants, and effective studies for assessing the environmental and health risks/impacts.
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.
