Blind Channel, which is between East and West Thurlow Islands about 35 km north of Campbell River, is about as good a testing ground as you could get for tidal power technology.
That含羞草研究社檚 why PRIMED (Pacific Regional Institute for Marine Energy Discovery), University of Victoria含羞草研究社檚 marine energy tech institute, has plans to set up a kind of showcase there for clean, marine-based energy generation that will hopefully be one day powering small communities up and down the coast.
Thanks to a $2 million injection from the Province of B.C. those plans are getting closer to fruition.
含羞草研究社淭he hope is that it will act as a site where communities can come (and) they can see, with their own eyes, this technology in operation,含羞草研究社� said Ben Whitby, a research engineer with PRIMED. 含羞草研究社淭he idea is that we would share a lot of the generation data, a lot of the the fuel usage data. We would have data on how much diesel the technology was displacing and we would look to share that data with these communities that we含羞草研究社檝e developed relationships with so they would be kept in the loop throughout the operation of the project.含羞草研究社�
In 2017, the area含羞草研究社檚 potential for tidal generation was first put to the test. At the time, Mavi Innovations set up a small turbine to demonstrate that such a device could work. Though there were a few shut down periods due to debris fouling the turbine mechanism, the turbine largely remained functional for two years until the funding ran out.
含羞草研究社淭he goal at the outset was simply to get a device in the water and demonstrate its operation and they more or less achieved those goals,含羞草研究社� Whitby said. 含羞草研究社淭he device operated for about two years and it exported power into a local resort located on West Thurlow Island: The Blind Channel Wilderness Resort.含羞草研究社�
The PRIMED project builds on the legacy of that Mavi project, using the infrastructure that was put out there for the initial turbine.
What含羞草研究社檚 different is the scale. PRIMED is planning to set up a 120 kilowatt device, compared to the 25 kilowatt Mavi project. PRIMED also intends on building out a small microgrid on land that will be powered by the tidal turbine, wind power and solar energy.
Whitby said the microgrid would help demonstrate 含羞草研究社渢he diesel displacement capability of a tidal device connected into a small remote community, of which there are many in B.C. The hope is that that side will act as a sort of shop window for other communities on the B.C. coast who may含羞草研究社� look to adopt similar technologies in their communities.含羞草研究社�
The power generated by the 120 kilowatt turbine will be over the capacity of the microgrid, but Whitby and his team won含羞草研究社檛 be wasting the excess energy. Instead, they含羞草研究社檒l be looking to produce clean hydrogen that can then be used as a product elsewhere for other power generation.
含羞草研究社淚f we scale up the tidal berth, but then obviously we含羞草研究社檙e not necessarily going to be able to use all of that extra capacity at the load,含羞草研究社� Whitby said. 含羞草研究社淎nd so where we含羞草研究社檙e going to need some means of storage. I mean the easiest way would just be to sort of burn off the excess capacity, you know, we would have a big resistive load dump or something, but it would make more sense to try and store that energy含羞草研究社� the hydrogen would be produced on site and we could potentially send it somewhere else where it could be used.含羞草研究社�
Whitby did acknowledge that there are concerns about the equipment surviving in that stretch of water for years, but said that 含羞草研究社渢hat含羞草研究社檚 part of the reason we含羞草研究社檙e doing the project.含羞草研究社�
The goal is to show the potential for communities who need this kind of technology to transition from diesel generation to a more sustainable option. The plan is to start construction this fall.
