Reducing Costs of Tidal Energy through a Comprehensive Characterization of Turbulence in Minas Passage
October 2017 – March 2020
Turbulence is a significant issue at every site being considered for in-stream tidal energy development.
Developing Enhanced Marine Operations (DEMO) in High Flow Tidal Environments
October 2017 – October 2019
Conventional subsea remotely operated vehicles (ROVs) perform poorly in currents exceeding 1.5 m/s. This is a key operating limitation in the success and cost of marine operations in the Bay of Fundy, where current speeds reach 5 m/s.
Performance validation of a remotely operated vehicle (ROV) in a controlled environment
June 2018 – October 2019
In the past few years, the Nova Scotia tidal community has augmented its marine operational capacity, but some unknowns and risks still exist and the cost associated with such operations are high.
Multi-Scale Turbulence Measurement in the Aquatron Laboratory
July 2018 – July 2019
This project has two primary objectives - to characterize the flow and turbulence in the Aquatron facility pool tank using turbulence sensors calibrated against a traceable standard; and to test technologies for investigating the horizontal variability of turbulence in real-world tidal channels.
Testing of a New Turbine Blade Design and Blade Materials
July 2018 – May 2019
There’s not yet a standardized, optimal way of extracting power from tidal currents. That’s why many tidal industry technologies are currently being tested around the world.
Remote Acoustic Measurements of Turbulence in High-Flow Tidal Channels during High Wave Conditions
April 2018 – April 2019
Many of the high-flow tidal channels targeted for worldwide in-stream hydro-electric development are impacted by surface gravity waves incident from a large exterior basin (e.g. the Bay of Fundy/Gulf of Maine/North Atlantic).
Optimized Combinations of Tidal, Wind and Solar Electricity Generation with Energy Storage to Meet Nova Scotia’s Electrical Demand
August 2018 – March 2019
Wind, solar and tidal-generated electricity each have different, but potentially complimentary, cyclic times.
Innovative Solutions for De-risking Species Detections in Tidal Energy Environmental Effects Monitoring Programs
April 2018 – March 2019
With collaboration from Genome Atlantic, this research project is using a new environmental DNA technology to rapidly identify and determine abundance of different fish species in high-flow marine conditions. Experiments were conducted at Dalhousie University’s Aquatron facility. N
Turbine Wake Characterization
November 2017 – March 2019
Turbine wake characterization is a key endeavour to the development of in-stream tidal turbine arrays. In a sense, a turbine’s footprint includes its wake, wherein flow speeds are less and turbulence is elevated compared to the ambient surroundings. It is thus desired to not just delineate wake
STREEM: Sensor Testing Research for Environmental Effects Monitoring
October 2018 – March 2019
The research goal was to enhance understanding on sensor performance and sensor-to-sensor interactions to inform environmental effects monitoring (EEM) protocol for future tidal turbine deployments.
