Liquefied natural gas (LNG) has up to 20% CO2 and 90% NOx fewer emissions than diesel; making it a cleaner alternative fuel for mobile applications. LNG has high volumetric energy density and is cost effective ($0.5 cheaper than diesel gallon equivalent). However, LNG is stored at low temperatures (-162ºC) and releases boil-off gas that contributes to the greenhouse gas (GHG) emissions. In collaboration with Westport Power Inc., the global leader in natural gas engines, we aim to identify the weaknesses in the LNG distribution chain to reduce the GHG emissions and the LNG delivery cost.
The dewatering systems in the FortisBC hydropower generation facilities need long-term rehabilitation solutions. The purpose of this project is to develop a risk assessment model for the dewatering systems of hydropower generation facilities, and to identify the best long-term rehabilitation solutions for such facilities. Recommendation on long-term maintenance and rehabilitation will be provided on the basis of failure risk, safety risk, maintainability, costs, and environmental impacts.
The proposed research will be focused on eliminating fugitive emissions from liquefied natural gas (LNG) transmission, storage, and distribution operations. LNG can be used as fuel for transportation, and for combined heat and power generation in remote locations. We will study transmission, storage, and distribution operations by developing quasi-steady-state and time-dependent thermodynamic models. These models will be validated using data from instrumented equipment at our industrial partnersâ sites (a small consortium has been created specifically to support the proposed research).
Traditional design method for the foundation of the transmission poles simply assigns a standard set of depths based on the length and diameter of poles. Although, this method has proven to be conservative and reliable, but it does not incorporate site-specific soil properties, water table, and weather conditions in its calculations. As a result, a new foundation design system which will integrate site specific conditions for each pole will provide more safe, economical, and reliable performance of transmission poles for the long-term benefit of FortisBC.
The purpose of the research project is to identify the main soil types found within the FortisBC Electric service territory and identify the best alternatives for power pole installations within each soil type. This information will be made readily available to power line designers for use when selecting the foundation alternative during the design process. The large number of power poles installed each year has created a need to streamline the design process and installation cost.
