Performance Assessment of a Vertical Kinetic Turbine in a Wake Zone

This internship will numerically simulate the impact of flow structures on power production from river kinetic turbines. These turbines extract renewable energy from rivers from flow velocity rather than from a drop in river levels. To date, a proper mathematical approach of how to place these turbines in a river is not available. Mathematic tools are required to estimate the power reduction when these turbines are subjected to large flow variations in river applications created by river bank profile changes, turbines located upstream, and due to localized changes in the river levels.

Demonstrations of the Hybrid Control concept for reducing vibration and noise on helicopters and wind turbines

Smart Rotor Systems Inc. (SRS) is a new Ottawa-based start-up company, whose product is a novel active control system for the reduction of vibration or noise on rotary wing applications, i.e. on helicopters and wind turbines. Mitigation of vibration and noise is a hot topic in both these sectors nowadays, attracting plenty of attention from both manufacturers and operators. SRS has the competitive edge in owning the Intellectual Property (IP) of the first ever electrically driven Active Pitch Link (APL) as well as for the concept of the control system driving it.

Fermentation of lignocellulosic feedstock after steam explosion pretreatment and enzymatic hydrolysis

Currently, cellulosic ethanol production is laden with technical challenges, and as a result, not economically viable. The reason for this lies with the toughness of the plant feed material generally called biomass. Processing biomass to allow fermentation to ethanol often requires harsh operations such as extreme heat, pressure, acidity, or a combination of all three. This often leads to the formation of unwanted chemicals that are toxic to organisms that enable fermentation.

Ice Throw from Wind Turbines

In cold climates there is a perception that ice fragments could be thrown from rotating large wind turbines and create a hazard. While turbines should be shut down in icing conditions several authorities now require calculation of the risk associated with this potential hazard, in terms of numbers of ice fragment strikes per unit area per year in areas surrounding a proposed wind farm. As service providers to the wind energy industry, Zephyr North wish to have an accurate, reliable model to provide this information.

Developing a Carbon Strategy for Publicly Held Canadian Forest Products Company

The objectives are to determine to what extent a carbon strategy can add to the value of a publicly held Canadian forest products firm, what form that would take, and what conditions would be required to implement. The project will begin with an environmental scan of economic, technological, political]legal, and societal trends that are occurring in the broader context. The focus will then be turned to identify the opportunities available and the company's core competencies (strengths) to take advantage of these opportunities.

Opportunities in BC to Generate Carbon Offsets from Biomass-based Renewable Energy

The focus of this project is an estimation of the potential in BC for economically viable biomass-based renewable energy projects capable of generating greenhouse has offsets.

Analysis of Plug-in Hybrid Electric Vehicles in Distribution Networks

Plug-in Hybrid Electric Vehicles are hybrid vehicles with large batteries that are capable of travelling on electricity but still maintain the reliability of an on‐board internal combustion engine for extended trips. The batteries will typically be recharged from a standard household outlet, thus increasing the demand for electricity. It is important to understand and predict how these vehicles will affect the operation and planning of networks in British Columbia.

Mattamy Homes Green Initiative Program

This research project proposes the exploration of various mechanical systems configured in two residential homes in Milton, Ontario. The primary goal is to determine the energy consumption and monetary costs associated with integrating new technologies of both heating and cooling requirements of a new home. Refinement of previously collected data and software modeling are keys to providing successful long term projections on potential savings in energy usage and economic payback periods.

Leveraging Smart Growth via Ontario’s Climate Commitments

A strategic opportunity exists to integrate, strengthen and reform land use, transportation and municipal energy planning policies to address climate change goals in Ontario. The kinds of policies that reduce urban sprawl go hand in hand with climate policy, and vice versa. The project with the Pembina Institute, an organization committed to sustainable energy solutions, will analyze existing government initiatives and relevant government policies to determine opportunities for Green House Gas (GHG) reductions through policy modifications or additions.

Assessing and enhancing energy-production performance of wind-power sites in operation

Energy-production performance is one of the most frequently analyzed parameters by wind-power site operators. Carrying out performance assessments is not usually a technical challenge for so-called conventional sites. However, the complex nature of winds and their interaction with turbines does make it difficult to assess wind-power performance. To date, only standard CEI 61400-12-1, which assesses performance for a single turbine at a time, is accepted industry-wide. In addition, it is a relatively onerous method.
