00:00J'espère que c'était intéressant pour vous, mais ne pas pas, nous allons continuer de continuer à partir de
00:06l'heure du matin.
00:07Nous allons maintenant passer de l'exoskeletons à la solution de clean énergie.
00:13Donc, les prochaines startups ont une très grande idée.
00:18Et c'est assez dangereux quand il concerne l'électricité.
00:22Ici, pour vous parler de plus, c'est Louis de SWITCH.
00:32Hello, everyone.
00:34So, we at SWITCH have developed a technology based on a realization,
00:41which is that by 2050, there will be a huge increase in electricity demand
00:47that will be matched by renewables.
00:49But that means there will still be 50% in fossil fuels that will still be used.
00:55And we have thought that the only way to actually counter that is for us to discover new sources of
01:01renewable energies.
01:02And this is where we come in at SWITCH with asmotic energy.
01:07So, asmotic energy is the energy that is released when you have fresh and salt water that mix.
01:13Essentially, by nature, those two flows of water will want to equalize themselves in terms of salinity.
01:19And salt is ions.
01:21And what we have developed at SWITCH is a membrane which can harness those ionic currents
01:28and transform them into electricity.
01:31And that is actually quite a big step because osmotic energy is not only renewable,
01:36but it's also entirely permanent.
01:38So, you don't have the intermittency you have with traditional wind or solar.
01:43On top of this, it's a massive, massive energy.
01:46At scale, there's more than 30,000 terawatt hours that are being released every year.
01:51That's more than the world energy consumption.
01:55What it looks like...
01:57So, this is our prototype.
01:59So, within this, you have about 400 membranes producing clean energy continuously on a worldwide scale.
02:05Currently, we are in the industrial phase.
02:09So, we have now left the lab and are going to deploy massively everywhere.
02:16This is what the future of energy looks like.
02:21So, we have developed a system that is entirely modular.
02:24It works a bit like Legos.
02:27You can put them on dams.
02:30Sorry.
02:31On shores.
02:32You can put them within the water.
02:34And you can produce with those using salinity gradients.
02:37So, you pump on one side the salt water from the sea.
02:40On the other, the fresh water from the river.
02:42And what you only release is mixed water back in the estuary where it happens naturally.
02:47So, we are not actually impacting anything.
02:49We are only concentrating on natural energy and putting it back where it belongs.
02:54We don't actually impact anything.
02:57With this, we could produce up to 15% of global energy consumption.
03:02For us, our objective within the next 10 years is to produce 3 gigawatts of energy.
03:09So, 3 gigawatts is incredible for a company like us that, you know, to do in only 10 years.
03:15But it's not going to change the world, is it?
03:17That's why what we actually believe at Switch is that we will show the world this energy works.
03:23And then we will structure an industry.
03:26And we need new energy players to come in as well and help us.
03:30And that starts next year.
03:33So, beginning of 2024, we have the first asmotic power plant.
03:37It's a demonstrator that's coming out on the Rhone River in France.
03:40We're doing it with our industrial partner, CNR.
03:44So, who are the Compagnie National de Rhone, a French utility in the south of France.
03:49Why are you on the Rhone River?
03:50Because the Rhone River is the biggest potential in France.
03:53There's only over 500 megawatts to actually go and harness on the Rhone River.
03:59I don't know if that speaks to everyone, but that's the equivalent of the electricity consumption of Montréal or Amsterdam.
04:08Ultimately, at scale, I said before, we have 15% of energy consumption.
04:13Our industrial partners are EDF at the minute and CNR.
04:17But we're looking to deploy massively from 2024 onwards, with the first megawatts being produced by 2025.
04:25That was it for me, Switch Energy. If you have any questions, let me please answer them.
04:35Ladies and gentlemen, Switch!
04:38Thank you, thank you. We've got to keep this running, this one.
04:42All right.
04:42Okay, now on to our next solution.
04:46These guys come from Norway, and they have a wind turbine, which is actually movable.
04:53You can see it just here in front of me.
04:55And here to tell us more is Stian from World Wide Wind.
05:06Hello everyone, I'm Stian from Norway, so bear with me.
05:10Yes, we are actually developing the largest moving object on Earth.
05:17So this is a new turbine, you know, the conventional turbines have a top-heavy nacelle.
05:23They need to go offshore, they need a big platform to replicate land, to make it stand still,
05:29because the angle could be more than five degrees.
05:34So what we have done, we have to take inspiration from the sailboats.
05:38So we have the heavy stock down there, so the generator that weighs really much.
05:44It's down there, under the water, and then we have a floater, and then we have the sail-like two
05:50counter-rotating turbines.
05:52And one of the turbines removes the stator, which usually stands still, and the other rotates the rotor.
06:02And that takes the torque out of the mooring, that's really, really important.
06:08So this construction is 500 meters high, and it generates 40 megawatts.
06:15We can even scale to 90 megawatts in the future.
06:18And it's really sustainable, we use wood, glulam in the mast, we use aluminum, so the whole thing is recyclable.
06:27So what we do, we are testing it now, we will do a demonstration.
06:33The first prototype will be finished within August, and then we will move to, and that's 30 kilowatt in Sweden.
06:39And then we will move to 1.5 megawatt, and we will build 10 of those, rapid prototyping, like Elon
06:46Musk does.
06:47And then we will go to 24 megawatt within five years, and then to this one, and even scale further.
06:55So this is the really only way to do offshore wind.
07:00Okay?
07:01So, and the important thing to notice today, you know, there are not enough vessels, so, and not enough cranes
07:12to do the commercial turbines out offshore.
07:15We don't need vessels, or those big cranes.
07:20We tow it out to the sea, horizontally, and then we use the gravitation to raise it, because it's so
07:27heavy down in the bottom.
07:29And then we unfold the blades like an umbrella.
07:33So you don't need that much, you know, special vessels, and you don't need that much energy to do that
07:41either.
07:43So this, this will be, will be the future of floating wind, and I don't know if you have any
07:49questions, but feel free.
07:53Any questions?
07:55No? Okay, then I will.
07:58Any questions from Stia?
08:01I can, I can, I can just keep on.
08:04So, the thing is, we are raising money now.
08:06So if you have some money in a pocket, and we also take card.
08:11This, so you guys are here, right?
08:13Yes, we are standing right there in the booth right there.
08:16Okay, so this is basically, it's a wind turbine that actually can be moved.
08:20Is it connected by cable to something? Is that how it works?
08:23It's connected by cables to land, yes, like the conventional turbines.
08:29Yeah. And, yeah, it's nothing, there's much to say.
08:33It's the way we, we want to scale it.
08:36We have to build, you know, a lot of fabrics all over the world.
08:41And we are doing something in India, and we are doing in Japan, we are doing it in Norway, and
08:49also in the US.
08:51So we try to, you know, when we do develop, we also try to build it rapidly, to find a
08:59way to scale this,
09:01so to get it all offshore really quick, because the world really needs this.
09:06Yeah, yeah. What is the lifespan of one of these things?
09:08It's 50 years.
09:1050 years, okay.
09:11Yes, and the maintenance is one time in every 15 years.
09:15Every 15 years to maintain it?
09:17Yes.
09:17Okay, so it's basically cheap to manufacture?
09:19Yeah, it's just, it's cheap to manufacture.
09:22It's one-fifth of the mass.
09:24Yeah.
09:24Compared, it's combined to the world.
09:26All those big things, they cost a fortune, and plus you have to dig them right into the floor, right?
09:31No.
09:32The big, I mean, it's all about the main ones, right?
09:34Yes, for sure, yeah.
09:34Yeah, so the thing is, and we don't need, you know, that much maintenance either, so it's really sustainable, the
09:44whole thing.
09:45Okay, that's all we have time for, Stian.
09:48Thank you.
09:48World Wide Wind.
09:49Thank you.
