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.
ThatB次元官网网址檚 why PRIMED (Pacific Regional Institute for Marine Energy Discovery), University of VictoriaB次元官网网址檚 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.
B次元官网网址淭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,B次元官网网址� said Ben Whitby, a research engineer with PRIMED. B次元官网网址淭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 weB次元官网网址檝e developed relationships with so they would be kept in the loop throughout the operation of the project.B次元官网网址�
In 2017, the areaB次元官网网址檚 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.
B次元官网网址淭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,B次元官网网址� Whitby said. B次元官网网址淭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.B次元官网网址�
The PRIMED project builds on the legacy of that Mavi project, using the infrastructure that was put out there for the initial turbine.
WhatB次元官网网址檚 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 B次元官网网址渢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 mayB次元官网网址� look to adopt similar technologies in their communities.B次元官网网址�
The power generated by the 120 kilowatt turbine will be over the capacity of the microgrid, but Whitby and his team wonB次元官网网址檛 be wasting the excess energy. Instead, theyB次元官网网址檒l be looking to produce clean hydrogen that can then be used as a product elsewhere for other power generation.
B次元官网网址淚f we scale up the tidal berth, but then obviously weB次元官网网址檙e not necessarily going to be able to use all of that extra capacity at the load,B次元官网网址� Whitby said. B次元官网网址淎nd so where weB次元官网网址檙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 energyB次元官网网址� the hydrogen would be produced on site and we could potentially send it somewhere else where it could be used.B次元官网网址�
Whitby did acknowledge that there are concerns about the equipment surviving in that stretch of water for years, but said that B次元官网网址渢hatB次元官网网址檚 part of the reason weB次元官网网址檙e doing the project.B次元官网网址�
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.
