Join me, Trevor Freeman, as I explore the traditional, unconventional and up and coming facets of the energy industry. If you have any thoughts, feedback or ideas for topics we should cover, please reach out to us at think energy at hydro ottawa.com, hi everyone, and welcome back. Today's episode brings us back to a few elements of my own personal history. Now you'll have to bear with me for a minute or two while I dive into my past in order to properly set up today's conversation, I grew up in southwestern Ontario, in and just outside the border town of Windsor, Ontario. Now for those of you not familiar with this area, Windsor and its surroundings are the most southern part of Canada. It might surprise you to know that Windsor is at the same latitude as Northern California and Rome, Italy. You can imagine that after growing up in Windsor and then living in various places around the globe, when I finally settled down here in Ottawa, adjusting to the more stereotypical Canadian winters of this northern capital, took a little bit of getting used to Windsor is so far south when you cross the border to its neighboring American city, Detroit, Michigan, you actually travel north. Have a look at a map if this seems to defy logic, but I promise you, it's true. This is the area that I grew up in. It's also where I went to school and got my engineering degree. More on that in a minute. Now, if you've ever driven down to the southwestern end of the 401 going past London and Chatham, you will notice two things. First, it is flat, very flat. You will not see a meaningful Hill anywhere in sight. I often joke with people that I used to toboggan when we did get any meaningful snow off of highway overpasses, because that was the only hill we could find. I was only partly joking, and I have indeed tobogganed off of said overpasses in my young and foolish days. But that is a story for another time. That brings us to the second thing you'll see, which is wind turbines. A lot of wind turbines. They are seemingly everywhere, stretching as far as you can see, southwestern Ontario is a hotbed of wind energy generation. Finally, a hint at why I'm going on about this part of the province on an energy podcast. But before we get into it, there's one other thing to touch on, and that is the fact that this area is also home to a large number of greenhouses growing produce year-round, as well as manufacturing. Windsor and its surrounding area is the automotive capital of Canada, with a number of plants from major car companies, as well as a supporting ecosystem of parts manufacturers. Incidentally, that's where I started my career, working as an environmental engineer for one of the automakers, and many members of my family have also worked or still work in that industry. The reason I bring up greenhouses in the auto industry is because they have some very high energy demand profiles, and that is how we get for me going on nostalgically about the area I grew up in, to our conversation today, I recently caught up with one of my engineering professors, Dr Rupp Carriveau, about the work that he and his colleagues have been doing that ties all of this together. And I thought it would be great to have him on the show to talk about that. Dr. Carriveau is the director of the Environmental Energy Institute and co-director of the Turbulence and Energy Lab and the CO lead of AGUwin at the University of Windsor. Back in the day, he was my fluid dynamics professor. But today, he balances his teaching duties with research into energy systems futures and advanced agricultural systems. He is a founder of the offshore energy and storage society, a recipient of the University Scholar Award, and has been named to Canada's clean 50 for his contributions to clean capitalism. Dr Rupp Carriveau, welcome to the show. Dr Rupp Carriveau 03:59 Trevor, great to be here. Thanks. Trevor Freeman 04:01 Yeah. So, Rupp, the last time we chatted, well, so you and I chatted a couple weeks ago, but before that, the last time that you and I interacted, I was in third year university. You were my fluid dynamics Prof. So, in addition to your professorial duties, you're now the director of the environmental Energy Institute at the University of Windsor. So, there's two questions around that. First off, how did you end up going from my fluid dynamics prof a number of years ago, probably close to 20 years ago now, to running this institute? And tell us a little bit about what the Institute does. Dr Rupp Carriveau 04:40 Sure. Though. So, thanks. Yeah, and very memorable Trevor, because I, you know, I remember you well. And, yeah, that was, that was a very nice class that we had. I remember, well, I remember your colleagues too. Trevor Freeman 04:54 If there's one thing I do, well, it's, it's be memorable, and you can take that however you want. Dr Rupp Carriveau 04:58 That is, that is. Something to be said for that. Yeah, thanks for that question. So I should point out that in addition to EEI, I am a co-director in the Turbulence and Energy Lab, which is really where all of the EEI initiatives have started from, that's a lab that I co supervise with Dr David Ting in mechanical engineering and the nuts and bolts, the very serious engineering side of things, comes out of the Turbulence and Energy Lab. EEI kind of came about to handle topics that were, frankly speaking, less interesting to Dr Ting. So, things that push more, a little bit more into policy wider systems looks at things as opposed to, you know, pure thermodynamics and energy efficiency type pursuits, which underpin a lot of the EEI policy pieces, but are sort of beyond the scope of what turbulence and energy lab does. So those two things, and then more recently, actually, I'm co lead on, AGUwin, which is like a center of excellence, emerging Center of Excellence at the University of Windsor. So, Agriculture U Windsor is a group of about 40 professors that do work in agriculture in some shape or form. And we've, we've, we've taken to organizing that movement in seeking sort of group funding proposals, developing curriculum and organized sort of platforms to help industry in agriculture. And it's, it's really taking off, which I'm really excited about my extremely hard-working colleagues and CO lead, Isabel Barrett-Ng, she in particular, has been really driving a lot of really cool initiatives ahead and all the people that work with us. So, yeah, lots, lots happening at the University since I saw you last. But you know, time has a way of helping with that, people find ways to find efficiencies and get to do and build on, build on, hopefully incremental progress. Trevor Freeman 07:08 Yeah, very cool. And you're teasing a few of the areas our conversation is going to go today, that sort of intersection between agriculture and obviously, this is an energy podcast, and so how does agriculture and the way we're moving in with agriculture impacts energy and vice versa. So, we're definitely going to get to that in a minute, I think, for our listeners that are not familiar with Southern Ontario, and I haven't talked about Southern Ontario on the podcast a lot, but people that know me know I will gladly talk about what goes on in the very southern part of our country. It's where I grew up. Help us paint a picture of what Southern Ontario is like. So, in the context of energy, what makes this area of Ontario unique? Dr Rupp Carriveau 07:50 Well, it's that's a really good question, and I'm glad you phrased it that way, because I think it gets taken for granted. And also, folks, folks don't know energy isn't in the headlines every day, and if it is, it's not a headline that everybody pays attention to. But the southwestern Ontario region, if you take the 401 west of London, you'll start to see a high concentration of wind. So, there's a significant wind corridor in the region, and that's because it's very flat, so the whole area used to be a lake bed, and so we have very fertile agricultural lands as a result of that. And we also have very few obstacles to fetch, which is a huge aspect of how wind carries over the lakes, and is, you know, not, not obstructed. And so it's like you have offshore resources onshore, which is completely ideal. Also, we have, as it may be, we have massive natural gas resources in the area, in sort of the subterranean space of Devonian reefs for natural gas storage. We have natural gas generation facilities down around the Windsor area that help with provincial peaking and there is some solar in the region, because it is the Leamington Kingsville area is referred to as the sun parlor of Ontario. And as a result, we have a lot of under glass agriculture there, which benefits, obviously, directly from solar resources. And then we have solar photovoltaic that takes advantage of that sun as well. So there's, there's a lot happening here energy wise. Trevor Freeman 09:38 Yeah, and there's a lot on the demand side of things as well. So, you mentioned the greenhouses, which are an up and coming, you know, source of demand draws on our grid. There's also a big manufacturing base. Talk a little bit about the manufacturing base in the area. Yeah, yeah. And that's that gets into my next question is talking about some of the specific, unique energy needs of greenhouses. I think on the manufacturing side, you know, you mentioned the auto industry and the parts industry that supports it, you're seeing more. There's a battery plant being built now I think that, I think people have a sense of that, but greenhouses are this thing that I think a lot of folks don't think about. So, you talked about the magnitude of the load, the lighting side of things. What else is this like, a 24/7 load? Is this sector growing like? Tell us a little bit about, you know where things are going with greenhouses? Dr Rupp Carriveau 09:53 Yeah, thanks. So, yeah, I was, I was thinking about generation and, yeah, demand is. Significant we have. You know, Windsor has laid claim to Canada's automotive capital, and while I'm biased, I'd like to think it still is. And so we have significant manufacturing around the automotive industry, either automotive OEMs or tier one parts makers that have significant draws. We have Stellantis. Every minivan comes out of this area has come out of this area. The electric Dodge Charger comes out of this area. But there are engine plants for Ford, but they're also now, you know, sort of next generation transport technologies. You've talking about battery manufacturing. So, there's an enormous LG consortium with Stellantis here that's doing battery manufacturing. And so, these are huge loads that that add to existing and growing loads in the greenhouse space, which, again, I'll just mention it now, is something that isn't well understood. And we did a, we did a study for the province a couple years, three, four years ago. Now, I think grid Innovation Fund project that looked at sort of really getting into granular detailing of the loads that come with a lit greenhouse. A lot of people don't appreciate that a lit greenhouse, when switched on, depending on the lighting technology, depending on how it's used, can be like a 50-megawatt load, which is a significant load. And just imagine that's one so they can come on quickly, and they are non-trivial, significant loads. And so, this is something that we looked at trying to develop distributed energy resource sort of solutions for, because, simply speaking, you can't put up a new transmission line overnight, and we don't want to economically constrain the growth of the sector. Sure, yeah. I mean, it's, it's not a simple thing to characterize, because what you can take away from this is that these greenhouse developers are business dynamos, and frankly speaking, many of them do very well, because they're very good at what they do, and with the resources they have, they can largely do what they want. And if, if the infrastructure isn't there, they will build it so. So, you'll have folks that are operating off the grid, essentially not off the gas grid, of course, but they're using gas for cogeneration purposes, to produce heat for their crops, but also the electricity for their lights. So that is one aspect of it that further complicates how to figure out what these loads on the grid will be. But for the most part, of course, the grid provides quite clean and quite affordable electricity in the province, and you know where they can they want to be able to connect to the grid. Now, lights are designed to extend the growing day and extend the growing season as well. So, in terms of when they're switched on and how they're switched on, that is highly variable, and that is also something that is, I would say, in development, folks are looking at different ways to use intermittent lighting to be conscious of when peaking happens. It is dispatchable in a way, in that some growers are able to turn their lights off to avoid, you know, peaking charges. But again, there's a lot to manage. And, and it's, it's very complicated, both on the grid side and, and for the greenhouse grower. Trevor Freeman 14:38 Yeah, so you mentioned natural gas for cogen for heating as well. So, as we look to decarbonize all different aspects of the sector, we talk often on the show of what are the specific areas where decarbonization might be challenging. Is, is greenhouses one of those areas? And, and what are the options available for heating these spaces? Like, is it realistic to think that there's an electric solution here, or what? What's happening in that sector related to decarbonization? Dr Rupp Carriveau 15:10 Again, you've hit on a real sort of hot button issue for the for the sector, the trouble with natural gas is that it's spectacular. Oh, it's storable. It's dispatchable. It's a triple threat for greenhouses in the best way possible, because you can make your heat,…
