Welcome to Uptime Spotlight, shining light on wind. Energy’s brightest innovators. This is the Progress Powering tomorrow.

Allen Hall: Michael, welcome to the program.

Thanks, Allen. A pleasure.

Allen Hall: Well, this is gonna be a, a really interesting discussion today because, uh, I don’t know a lot about wave power, but. Obviously the world has made some substantial progress in wind and solar, but the ocean energy is still relatively unknown and. I want you to, just to paint the picture of the problem, what gap exists in renewable energy today that wave energy can fill?

Michael Henriksen: Thanks. Thanks. A yes. Uh, that’s right. So ocean energy as such. And we have, um, we are working with the wave energy side of the other things here in Wave Piston has a very large potential because there’s a lot of waves around us. We all feel it when we are out in the sea, when we’re out swimming or whatever.[00:01:00]

So what can it fill out that is that, that the, the interesting thing about wave energy is that is, um, timewise shift compared to wind. You know, it’s the wind that builds up the waves. The waves come, uh, the wind comes and goes, but the waves that keep rolling also afterwards. Yeah. So this timewise shift that gives some extra value.

Of the energy that you can actually produce at the same time, it’s actually also, it’s a more of stable resource. So you, you don’t have these large fluctuation, it, it, it comes slowly and then dies away slowly depending on where you are in the world, of course. And then the last for the least is it’s very predictable.

So stable days advantage, you can actually very precise predict what sort of your energy production profile. So by adding an extra renewable energy source, you can actually sort of, it gives extra value to both have sort as much solar PV as possible, as much wind as possible, but also have wave energy there to have sort of a better, uh, in the end, uh, [00:02:00] uh, energy production.

Allen Hall: Yeah. And that, and the technology is really applicable to, uh, a lot of regions, uh, around just like island communities and places of a little more remote. Uh, because the cost of electricity on islands is incredibly high. They’re buying diesel usually, and they have a kind of a, a double problem in that they have to buy diesel to run electricity plants, and then at the same time they’re, they’re having to make fresh water all the time ’cause fresh water’s a problem.

Wave Piston solves both of these problems together. But why are we in this? Space right now. I, I just wanna back up a minute. I mean, there, there does seem like for the last 30, 40 years that I can remember, the island communities have been really stuck. Solar hasn’t really filled the void. Wind has been intermittent option at times.

Why waves?

Michael Henriksen: Yeah. But that’s actually, uh, where we see our, like our step to, uh, [00:03:00] you know, uh, go to market strategy, so to speak. See, that is the first step because as you mentioned, all the island communities, I would also say remote coastal communities still have this, this challenge of being dependent on fossil fuels.

And as you know, it’s, it’s mainly because of course you have limited, uh, uh, uh, land space. Uh, of course they should have as much solar PB as wind as possible, but you still have this, you know, you don’t wanna have it in your backyard. It’s difficult to have, you know, spatial beautiful islands where you have, uh, tourism, et cetera.

And then you have, uh, solar PB and winter turbines all over the place. It’s not gonna happen. So they’re looking at to go to, of course, offshore. What they have a lot of us is they have ocean. Yeah. And the challenge there again, is. Most places when you go just a few kilometers from shore get very, very deep.

Yeah. So you need to find something that is sustainable, something that it will not spoil the view. Something that is actually, uh, uh, an [00:04:00]environmental friendly way, you know, of harnessing the energy that that is where wave energy come into the picture because. It’s happening below the sea. So the, the surface and, and, and the, it can sort of coexist with other things happening there.

Of course, you need to have an area where just say this is for wave minute. Yeah. But you don’t, so sort of spoil view. You don’t have this issue with the, not in my background as such. So, so, so by coming in, of course we will be at another cost level to begin with. Yeah. By coming in, taking that part of it, then we can actually be a part of solutions for these remote islands and the coastal communities.

Allen Hall: Well, because some of these islands are spending more than 10% of the GDP just on energy to import it. That’s. Really high and a, on a big burden on the economy is how do you see wave piston affecting that?

Michael Henriksen: But it’s just actually that is this, uh, it’s, it’s both, you know, in the first phase, of course, the islands in milk richi, but also you can say [00:05:00] countries as such that are dependent on fossil.

Because you can just reduce your dependency and also these volatility of the price. Uh, but, but go coming back to wave piece, of course we, uh, the special thing about our system is that we actually, we can both produce electricity and we can also desalinate sea water ’cause it’s hydraulic system. So this about coming into an island community where they have both these challenges.

We can actually come with a double. Sort of a, uh, solution and then, uh, work with how much energy you need, how much water you need at a given time. It could be an off grid solution or an on grid or micro grid, whatever, where, where, where. That makes sense. Yeah. So coming in and that’s actually why there is a big uh, uh, sort of.

Focus on wave, not only on us, but also others in the sector, that we can be a part of the solution, which is actually when you come with a new thing, you need to sort of to say, okay, this is new, this is fantastic. But you also need to say, okay, we are part of the solution now. We are solving some of the problems you have.

We’re not [00:06:00] creating new ones. Or maybe you not, not, there’s always some challenges, but we are not creating that many of big ones. You know? We are solving things. Yeah, we’re solving. Your challenges?

Allen Hall: Well, e even if you look beyond the island, island economies, uh, there’s a bigger picture here about renewable energy sector that is not really considered wave energy too much, especially for offshore wind, right?

There’s, uh, uh, offshore wind, particularly in the North Sea and off the coast of England and other places where there’s our massive wave resources. We haven’t really addressed that at all. Are we missing out on a, on a lot of energy production? That would be relatively easy to go get.

Michael Henriksen: We are missing out.

That’s the, the, the short, the short, uh, uh, answers there. Of course, we see relatively easy need to look at the relatively side of it because it is difficult going offshore. You know why? But it’s also why I’m asking. It’s actually why it hasn’t wave energy succeeded so far. Well, that’s simply because it’s [00:07:00]not the low hanging fruit.

Now being able to take a wind turbine. You know, in Denmark it was the farmer....
