Wow, most impressive. As an Australian, and the worlds largest island, we should be doing this ourselves. But like you said, its Govt incentive that kicks it off, and we havent had effective Govt in about 15 years
Surely the crux move is to combine a wind turbine with a wave turbine (and maybe an energy store too) ie, the post that holds the wind turbine up also holds a tide turbine down! The Tide energy gives you your forecast able energy, and the wind adds the peak output.
Pretty sure they will tend to be exposed coast areas facing large stretches of water, so good enough for both. Might not be the best tide generation places, but will have enough flow to make a big difference, seeing as the wind plant puts down the same heavy anchor, which is a large part of the cost, to anchor it, so the floating tide generator or an anchored one is a minor added cost, all the rest is already there.
@@iAmTheSquidThing Dong Energy is building a massive offshore turbine farm in the straights of Anholt, which coincidentally has some of the strongest tidal flows in all of europe. Frankly I'm surprised they didn't add tidal turbines to the bases of those as well.
Thank you for showing the beautiful Islands. I live on the East Coast of the US. I really enjoy your videos. It is so nice to see homeowners take control of there future, as homeowners. It is so important to talk about our future.
Turning on subtitles, confirms what you think you are hearing and it's gold to someone not really used to hearing the Scottish translation of English ;-D
Tidal and wind energy capture is an absolute gem of a technology to possess. No matter what the climate is and no matter what sort of nuclear winter we find ourselves in, we can still harness the effects that the celestial bodies around us perform on our planet and create enough energy to sustain sanctuaries of civilisation. This needs so much funding and innovation but it's likely to be the most worthwhile system for generations to come.
The Orkneys are such an incredible example of the good thinking ahead provides... meanwhile the petroleum industry desperately tries to drill in more and more places when we need less of the crap !! Great video as always Kryten... erm, *Mr. Llewellyn* !!!
Absolutely incredible. Thank you to those industries for allowing us viewers to geek out on your amazing technological advances. I’m so glad that graphic or animation was shown else I would have had no appreciation for what was under the water. Just incredible. Well done to everyone pioneering these technologies.
So lucky to have all these resources. Where I live we are getting less and less precipitation every year and the summers are very very noticeably getting longer. I'm 25 and even I can feel the change compared to when I was say, 15 or even 20. Right now, I _should_ have the heater on, instead I'm sitting under the AC
I am currently doing my Enviro Eng MSc with offshore wind farms in my sights, but this tidal technology has huge potential when you consider the amount of MW you could get out of a square km (compared to wind which require more space). Great video with really positive information.
another great production Robert you should come and visit Jersey and see the massive tides, huge wealth and non-existent renewable spending for an interesting contrast show !
I have been watching, and thank you for making the videos. I have been watching the back videos and I'm almost caught up on the videos. After watching this series, I'm thinking of moving to Orkney.
The shots are great, but for the Patreon money we give, I think the next step would be to bring in somebody for part-time gigs that has an engineering background, supplying you with questions about technical specifications, further development options and costs about the things you are reviewing :D I know you are not an engineer type of bloke, but this kind of info would make your show much more informative than it already is. Cheers from Slovenia, Robby (I hope you don't mind a casual nickname :D )
Peter Faber They're in the goldfish bowl! If they realised the potential and actually applied their expertise to exploit Wind, Wave, and tidal flow, they could make serious profit!
Gordon L Seriously. The risk of that is minuscule. If so, why weren’t they wearing hard hats on the next boat. It’s just some silly rule that gives H&S a bad name.
Hugh Marcus It’s the issue of bashing your head going through doors, up and down stairs, and so forth. Ships are a bit more hazardous than your standard office environment.
It's also about litigation and compensation, because everyone knows you can only trip and bump your head in the work environment so if you do so you can call an ambulance chaser and take your boss to the cleaners.
Thanks for the Video - A few questions: 1) The first moveable solution - how does it /or is it supposed to transfer the power to the grid ??. 2) What is the power output of the second solution (the Stationary one)?. I find the movable solution very interesting - this kind of technology could lead to hybrid ship drives - e.g. When a ship lays at anchor, its usual propeller could act as a power generator, that is if there is stream enough off course - But many places around the world hold strong streams - essentially such places could be natural charging stations for such systems.
We experimented in New York City with I think small ones about 5 years ago off Roosevelt Island but I do not believe it went further than that here. Too bad!
funniest thing about people who say perpetual motion or over unity devices are fake is they actually exist as tidal energy devices... think about it the oscillating water column requires only a small bit of energy to get the fan blades started and then the force of the waves keeps the air flow going until maintenance is needed, these devices produce dramatically more power then they consume so they technically fall into the "Over Unity Devices" category, and the other devices that just harness the movement of the waves usually require the same very small amounts of starting energy if any at all and then they just run off the waves technically the waves and movement of water is considered perpetual motion because it appears to be continuous and unceasing.
Kr!rk, as usual, when you analyse the system it proves not to be a very good or effective way to generate power. Once again, like all renewables, asynchronous, no inertia and intermittent. The fact that you know when it happens doesn't help. Add to that horrendous maintenace liabilities and it makes little sense to pursue such schemes.
Great show Robert. Could you do a review of the kite turbines used by Minesto? Your opinion would be intressting... They have launched in Holyhead Deep but I don't know how it's progressing.
The speed of the tide taken from the drone, was amazing. Is that deary deary me thing still likely to go ahead. As there has been some work going on in Hinkley, will we end up getting this against a lot of sensible thinking?
Are you refering to the energy generation done by companies like Minesto? I read an article about them about a year ago and the tecnology seems really promising since they use the "kite" motion to increase the flow-through velocity. I haven`t although heard anything since then so I'm wondering how it's progressing. As a follow-up to this episode could you Robert review and comment their technology? They have deployed their turbines at Holyhead Deep but I have no idea if it's up and running yet. Seems like a better idea thanks the surface based turbines. So it would be intressting to get Robert's opinion on it. Www.minesto.com... Thanks for an intressting show.
What a wonderful great presentation of the isles of orkney, if only english government can act quicker to present more funding and creativity within, imagine channel islands are given an upgrade in tidal power generation system near the ports of Dover. Dover would next place to live within a short decade with high efficiency of electric mobility.
Hi another great video. It would be interesting to know how may megawatt hours per year they hope these turbines will generate. In other words How many hours a day is a 2 megawatt turbine generating flat out?
Absolutely love the idea of tidal power. Are there any books or classes you would recommend on that subject? I'd love to move towards that in the future. Thanks!
I really hope that the timelines discussed for commercial versions are pessimistic - it would be fantastic to see these floating in packs around our shores! I'm surprised there was no discussion about any potential harm to wildlife as this is usually touted as the reason that they have yet to take off, did you discuss this element in any respect?
What's keeping us from putting these along all major rivers? I imagine it would have far less environmental impact than dams, at least per energy produced.
Building a dam you can use all the water that flows by to produce energy, but these would only produce a fraction of that as most of the water flows by. Also with a dam you can very quickly (within seconds) adjust to current electrcity demand which is one of the biggest advantages of common hydroelectric power.
Robert, I like watching your videos and I'm a big fan, but you don't always ask the relevant questions. Take this video, for the 1st and 2nd turbine, you didn't ask, 'how much do they cost to deploy?' and on the 2nd turbine you didn't ask 'how much power does it produce?' These are interesting questions because we could compare against coal and oil and see how viable these technologies are becoming. How about doing a comparison chart for each technology you look at? A 'fully charged, best renewable' score if you like.
I love the videos, but I also would love to hear the numbers as well. I know its new tech, and that things are subject to change, but its hard to really get excited over something that is otherwise so nebulous.
For a simple comparison, Atlantis, the developers of the first commercial scale tidal project slightly to the south of Orkney (MeyGen) put in a bid at the recent UK gov Contracts for Difference auction of ~£150MWh (a very competitive bid for this nascent industry), for the second phase of the project (up to 86 turbines - there are currently 4 for phase 1). The winning bids were by three offshore wind projects, one at (i think) ~£70MWh and the other two at £59MWh). These costs for offshore wind represent huge reductions (50% in 2 years) and as tidal had to compete against this much more advanced technology, it put them at a distinct disadvantage and risks the future of the Meygen project. The Government needs to ringfence this money for wave and tidal technologies, otherwise once again we will lose the head start we have with wave and tidal, like we did with wind.
Ok I'm not very technical minded, but if you had a big air turbine at the front of an electric car, would you be able to put a bit of charge back in the battery as you drive?
Aircraft use a similar thing, a small turbine that deploys below the plane in the event of losing all engines and thus electrical power - it generates enough electricity to run the instrumentation and power hydraulics but it also slows the plane down due to the extra drag. That's why if you put one on a car it would generate a bit of electricity but the car would also require a little more electricity or petrol to overcome the drag created by it.
I love the report and am pleased for a change our Government did think ahead and plan the funding for the tidal power systems to be researched? One little question here, the 2nd pillars type turbine they looked at in the 2nd half of the video.. was at a odd angle compared to the incoming tides! Should is be face on to any underwater flows not at a shallow angle like it was? About 20 degrees angle compared to the tide there.. should it be better placed face on to them to get the full flow through the turbine!Just seemed odd to have it facing at a non-full on angle? the flow of water would at that angle not only give you only about 20% of the full 100% But put huge strains on the turbine blades as the water would be pushing one side of blades more than the rest, sort off lob sided. Just saying please don't shoot me saying?
It is sitting in the tide, I shot the video and the boat I was flying from had to go quite fast through the water just to keep still relative to the ground.
Japanese tech company Toshiba has just announced their next-generation SCiB rechargeable batteries for electric vehicles. According to the company, these new batteries can charge in just six minutes and deliver a range of 200 miles.
So, if Scotland can take the excess wave and solar energy and store that as hydrogen, they can then be self-sufficient and power all the ferries once they have perfected the drive system. As previously mentioned, Scotland burns a lot of oil on ferries. Tankers also consume vast amounts of oil, so once they have got a good hydrogen system installed, that would save masses of CO2 from entering the atmosphere. Therefore it does make sense to have nuclear as backup until home PV/storage and EV cars are connected to the grid. Then you have a workable system. Now all we have to do is get the plastic and chemicals out of the sea and start to clean out the refuse pits where we have buried long terms pollution. Shares in these businesses will rise quickly as the stock market swings behind and endorses the change.
The problem is that hydrogen really doesn't like to be stored. Making containers where you can keep the hydrogen contained for even a week is really difficult. And extremely expensive.
The location the test area is in has a massive tidal flow, how many areas in the uk have a sufficient velocity of water to make it economic ......... Not too many I think
From what I remember being told a few years back, in and around the Scottish Islands there are about 140 locations suitable for tidal turbines, there is more than enough to capture energy to power the entire UK.
What an interesting episode. Far more informative than the article I read from itm power. I can't understand why renewable created hydrogen isn't in every corner of the country. I can't see the downside of it.
Unlikely, since the turbines move with the current and so do sea creatures. The speed these move at is not that great either. Also, the more closed design shown here, the one like a jet engine, has a hole in the center to allow fish etc to move through. Will there be zero casualties? Of course not. But it's not a blender.
Wow, most impressive. As an Australian, and the worlds largest island, we should be doing this ourselves. But like you said, its Govt incentive that kicks it off, and we havent had effective Govt in about 15 years
agreed
Robert, another great presentation
Thank you all involved for making Fully Charged and Red Dwarf Season 12. :)

The tidal turbine assembly would weaken the strength of the wind turbine pylon. That's a real concern in storms.
@@georgew2014 The old Dutch windmills had adjustable sails could not wind turbines have something similar adjusting to the strength of the wind?
Yet another very informative video.
Thanks to Robert and the crew ( pun intended :)

Great show Robert. Could you do a review of the kite turbines used by Minesto? Your opinion would be intressting... They have launched in Holyhead Deep but I don't know how it's progressing.
You should check out Minesto. Swedish company installing tidal power at the Faroe Islands now.
The speed of the tide taken from the drone, was amazing. Is that deary deary me thing still likely to go ahead. As there has been some work going on in Hinkley, will we end up getting this against a lot of sensible thinking?
the great thing here is that tidal power is relatively constant, the tidal rates dont vary that much i dont think.
Fantastic video as usual. Any chance you'll be covering kite-driven power generation (Makani and/or Kite Power Systems)?
Are you refering to the energy generation done by companies like Minesto?

Hi another great video. It would be interesting to know how may megawatt hours per year they hope these turbines will generate. In other words How many hours a day is a 2 megawatt turbine generating flat out?
I'm sure I'm an idiot but why does it take so long? It works, why not deploy on a large scale now?
Would love for you to ask about of there are any environmental events from these and what kinds of mitigation is being utilised
This research is inspirational. Now how do we get other governments to support responsibly generated electricity?
Absolutely love the idea of tidal power. Are there any books or classes you would recommend on that subject? I'd love to move towards that in the future. Thanks!
I really hope that the timelines discussed for commercial versions are pessimistic - it would be fantastic to see these floating in packs around our shores!
I'm surprised there was no discussion about any potential harm to wildlife as this is usually touted as the reason that they have yet to take off, did you discuss this element in any respect?

What power was the 2 fixed turbine producing ?
Robert, I like watching your videos and I'm a big fan, but you don't always ask the relevant questions. Take this video, for the 1st and 2nd turbine, you didn't ask, 'how much do they cost to deploy?' and on the 2nd turbine you didn't ask 'how much power does it produce?'

It is a research project.

They are very viable, & profitable that's why Meygen are deploying lots of tidal turbines in the Pentland Firth...

~£150MWh ? I know what MWh's are, and £ is the British pound right? So is that 150MWh/£? or 150£ / MWh?
How many people travel with you when you shoot your average location video?
Those turbines seem to not have guards around them to prevent sealife getting sliced up. I presume they are using some kind of sonar deterrent?
Probably just relying on the fact it's hard to slice something with a slow turning blade.
Could these be used in rivers?
Do you have a blackout a couple of times a day?
Ok I'm not very technical minded, but if you had a big air turbine at the front of an electric car, would you be able to put a bit of charge back in the battery as you drive?
haha, yes - but you will need more power to go forward as well. you need more extra energy than you will gain.
Look up the law of conservation of energy, to get a better idea about why this doesn't help.
CorwynGC ok will do thanks

im quite curious how that boat moved at 5:54
or is that thing just sitting in the tide ?
It is sitting in the tide, I shot the video and the boat I was flying from had to go quite fast through the water just to keep still relative to the ground.

The problem is that hydrogen really doesn't like to be stored. Making containers where you can keep the hydrogen contained for even a week is really difficult. And extremely expensive.
How much kW made the second turbine?
The location the test area is in has a massive tidal flow, how many areas in the uk have a sufficient velocity of water to make it economic ......... Not too many I think
From what I remember being told a few years back, in and around the Scottish Islands there are about 140 locations suitable for tidal turbines, there is more than enough to capture energy to power the entire UK.
There's the Severn as well with one of the most powerful tides in the world
The problem with tidal power is that it will add friction to the tides. Thereby slowing down the moon's orbit and sending it crashing into the Earth.
Living in a post Trump world I don't know if this is a clever joke or a serious comment.
True
You can trust people who edit there texts...
The moon is moving further away. More friction, which is trivial, would add to the slowing of our day length and add to the moon's move further way.
I bet Andy added the moon bit to make sure people know it's a joke.

Is tidal friendly to marine life?
Was just reading recently how they have connected a hydrogen generator to create free fuel for the ferry in Orkney. ITM power posted about it.
You clearly haven't seen this episode ruclips.net/video/Rybpaqhg5Qg/видео.html
What an interesting episode. Far more informative than the article I read from itm power. I can't understand why renewable created hydrogen isn't in every corner of the country. I can't see the downside of it.
Will the tidal turbine chew up the sea creatures that goes through the blades?
Unlikely, since the turbines move with the current and so do sea creatures. The speed these move at is not that great either. Also, the more closed design shown here, the one like a jet engine, has a hole in the center to allow fish etc to move through.
Will there be zero casualties? Of course not. But it's not a blender.
Doesn't it need a mesh to stop damage to wildlife?
