I've been following the progress of the Scottish tidal renewable energy sector for about the last 10 years. It's amazing to finally see it get to this stage. It would make me so happy to see this up and running in Scotland and take potentially get us to a place where almost all energy production in Scotland was from a zero carbon, or low carbon source.

@@cpowerbpower3339 End of they day, practice makes perfect. Extracting energy out of tides is one of the good energy sources to explore and build knowledge about.
I’m from the Scottish highlands and the fact we have so many massive wind turbines and only very little in the way of tidal power is sad. Where I live is next to the Isle of Skye and there’s a channel between it and the mainland where the tides race so very fast and strong….perfect! Anyway, it’s great to see the O2 do it’s thing and I hope to see many more around the world soon.
Great concept, sounds way more reliable as well. Solar panels break down way faster than I would assume that this would. Especially if they were able to use composites instead of steel to battle against deterioration
The O2 with two turbines is a good start to prove the technology. They need to ramp it up and make the future ships more productive. Put more turbines at key points front and rear to make the O6 with 6 turbines. Then add another length on each arm to get to the deeper currents and put turbines on them to make the O12 with twelve turbines.
Are you an engineer, or you're just speculating what needs to be done without actual knowledge? 😅 I'm just curious, i don't mean to be 'that guy' 😁 I was thinking that, for example, doubling the turbines might not translate in more power harnessed, because the first ones to encounter the tide will smother the power coming to the ones behind.
@@andreabrembilla6466 Not to be a wise guy, but you don't have to be an engineer to have knowledge, though I have found engineers are more likely to be able to tell you who back in the 14th century came up with the theorems or formulas you are using. Technically I am not an engineer as I do not hold that degree. To answer your concern: Just like wind turbines placed in a row that, at some times, point towards the other turbines in that row will still work, so will turbines driven by water. However, if you consider the fluid dynamics, there will be a tear shaped area of disrupted flow past each of the turbines that would result in poor turbine function within that wake. Proper flow experiments around the shape of the ship and optimizing the turbine spacing will be critical to correctly place the other turbines for maximizing captured energy.
@@johnlilley9363 Wind turbines do not really affect bird life, more specifically the amount they did affect can be further be reduced by 66 % by painting one blade a different colour typically black
99% of these very encouraging videos fail to mention any numbers for cost of investment, cost of ownership and maintenance and levelized cost of energy.
Of course they don’t and guess what it’s more then the tech that’s been around 100 plus years. Does that mean we shouldn’t explore. Do you think it would be cheaper after a hundred years of major research?
@@slipjones2 There hasn't been major research, but can it work, perhaps not. But today solar is the cheapest ever in form of energy in history. As all these tech, there will be winners and losers. For example this could become interesting to have a base load when the sun is not shinning, but battery cost could kill it in its shell.
This looks expensive and delicate to me. I like the wave energy solution that connects to land and shoots air at a turbine above the water. That seems like the most sturdy and cost effective. I forget the name of the company.
Simple turbine effect is used for example in jet engine (plasma, fuel, gas, etc) more multilevel blades means more bidrectional power. Adding also hydrophobic coating if used under water. And so on, and so on.
Great work Scotland, Keep on giving your best Thank you. A bridge from Scotland to Ireland with Marine turbines along structure could provide good energy. Electric trains could operate, powered by the marine turbines.
The idea sounds great but the real information needed is the cost per kWh. Also, are the tides around Orkney exceptional? I.e. how widely applicable is it and what are the constraints on its use? If this information was supplied we might be able to answer your question
Yes I believe so, there's a unique location within near the orkneys where there is a year long continuous tidal situation, therefore a great location for tidal.
The Fall of Warness tides produce 2-3m per sec (m/s) tidal speed and up to 4m/s. It is the tidal stream from the North Atlantic Ocean and the North Sea. They funnel through this Channel and no matter what time of year are 365. Better in the Spring Tides but always there. As for cost, there was a prototype which operated for a year but costs have not been disclosed. We all want to know what the kWh is but it should be low as it is cheap to build, transport and maintain. They should be congratulated and have just secured a strategic investment from TechnipFMC. I've been watching this Company since it was Scottisrenewables. Good luck to them
Definitely, but enough of these to power the whole world wouldn't even take up 1% of 1% of 1% of the oceans. It's much like the argument about wind turbines for birds - sure, they kill them, but far less than almost anything else in the environment.
They ought to put one of these waaaaay off shore in the Bay of Fundy. Fifty foot tides, that's eight fathoms. It's where tide waves and tidal waves rather blur.
I was a fan of renewables until I found out the damage they do to the ecosystem around them. They produce very little and have a short shelf life with little in the way of recycling. This is an interesting idea do to the lack of ecological damage. So long as its cost effective I think its great.
What's the impact of this turbine on its immediate environment during operation? Mechanical vibrations can be louder and travel much farther in water after all.
The answer to the world’s energy needs is not the production of more power but the reduction in the consumption of power and the only way to realistically achieve that is to reduce the demand for energy and to achieve a reduced demand requires a reduced population. And there are those currently in a position of power working on doing just that if you will only let them get on with it.
I've read "Energy from the Waves" written by David Ross in 1981 ! There were already 4 or 5 projects of tidal energy generators. 40 years have passed and what we have ?
It's all about baseload power - energy that can be reliably sustained. Tidal energy generation fits that bill. That has to be part of the makeup of future power delivery systems. However not every place in the world has tidal waters nearby. That's why we have to invest in the development and deployment of small, modular, factrory-built reactors. They are carbon-free, amazingly efficient, and they can be sited virtually anywhere. Need more power? Add more reactors.
Marine life will be able hear those turbines from miles away so its extremely unlikely that they'll swim into them. There is little destruction of the seabed, just two relatively small anchor points which can be placed in a minimally invasive way.
these turbines will not make nearly as much noise as a passing ship with huge diesel engines pushing the water... in fact i would think these would make very little noise as the water is pushing the blades and the blades are not forcing water through,.... good thing is it wont spill any oil sure... but um it will create huge electrical field... and that could be a problem as noted by power lines on land.....
Go have a look at "Just Have a Think" channel, he has a bit more details of the market and associated technologies. NB. Both utilise the marketing media from O2. I gather this unit is enough for 2,000 homes at an averaged installation cost of $5,500 per home. Economies of scale should halve this over the next 5-10 but I have no idea of the unit's life. Hopefully its better than the 10-25yrs for Solar Panels otherwise it doesn't hit the right price points.
@@chrisbeecraft Solar panels have a minimum lifespan of 25 years by guarantee now. 95% of those installed early enough are still producing 60% output at 30 years.
being predictable is a step up over wind... but it's still intermittent right? tides go in and out, but between going in and out they have to turn, at which point there will be a gap in energy production, not as much of an issue as with wind and solar, but still another case of renewable energy being less than ideal, seems that hydro and geothermal are still the only exceptions to this
Great video, but I am curious about the financials. How much does the ship cost, what is the cost of the mooring/docking infrastructure, what are its operation costs, how much power can it produce per day, and what percentage of the year can it operate (including expected maintenance and seasonal down times)?
Tides happen every 12:25 minutes between peaks or 6:12 between the high and low. All day, every day, every year, every millennia. It is rated at about 2 MW or enough to power 2000 homes.
@@sergeig685 yes but the same rational can be used for other power plants. Knowing the actual costs is crucial to knowing whether it truly makes sense/cents.
Great beautiful idea and design. One big serious question about this particular design....What types and how much lubricant is used in this device and how often is the oil change???
So i imagine if these are to be adopted massively we will see tens if not hundreds of these to supply to tens to hundreds of thousands of homes? Renewable energh tech are really interesting to look at but I think the biggest Achilles heel with renewable clean energy tech is the massive amount of space they need to be effective. Just look at the huge windfarms and solarfarms. This look like its going to be similar. I think the next big step for renewable clean energy is how to reduce the space required while increasing energy supply output, which seems like its going to be a very serious challenge.
It's good, on the maintenance accessibility side, but the harm to wildlife is the concern. There's many other wave energy options that don't have to interfere, and can also be made easy to access from depth to a surface level. I haven't looked that much into tidal, which is a different variable, but sad this can't be a solution when it shows it could work, if *not for the danger to marine life.
How much energy to built it ( all energy ...like mining and transporting the metals etc ...) vs how much energy is it going to deliver minus the maintenance ? Then you will know if it is profitable .
All of that for 2000 homes? Cant imagine the initial cost and then maintaining it makes ot cost effective. Very cool design that i think can find a niche market to reside in
If it's built in an array over a big area, will it slow down the currents? Any studies how that can effect the environment, salinity, temperature, etc.
what is the power output? how could you handle bad weather? it should have that caterpillar to more it to the shore.. and a tug boat always to keep it moving.. not a negative thought but you can go for a less tiresome option?
So actually how much the prototype create energy? 2000 homes x3000watt(?) = 6Mw? In 24 h. Tidal power can operate 24h right? Not like solar or wind.. And can this thing attach at ship..cruise ship, cargo ship,etc? Of course the estimate price/cost.. to build 1Mw cost $1M or $5M..and so on..?
Maintenance costs have historically been why ocean energy projects like this haven't succeeded. The service lifetime of the generating units is too short to be worth the cost per MW. Some potential I see for this is that it would be possible to detach units and tow them to shore for overhaul, which should lower maintenance cost for them. I still do feel that if we're looking for a strong, safe, powerful and cheap generation system, nuclear is pretty much it. Cost per MW in lives, environmental impact, materials and money is on par with or lower than any other generation technology.
@@autochton I agree some day in the future with projects like these we will develop the types of cost effective materials to mass produce and towing it to shore and lifting the blades is smart but to costly right now but i do love it I see so many wind mills sitting not running and needing maintained this requires more
This engineering marvel generates 2 Mw which is equivalent to 3 wind turbines operating with the standard 33% capacity factor. This factor takes into account the variability of wind power. This thing would surely cost at least 100 times what 3 of your typical wind turbines cost to build. As he said, any maintenance will cost 100 times what land based work costs. I don't see the economics ever making sense.
Wonder how long it’ll take to break even regarding the energy produced to make it as well as the material cost. Ocean water is harsh on materials, hope it’s resilient
Enough energy to power around 2000 homes does not sound very cost efficient to me. I like that it is clean energy, but I don't think it is very profitable. Maintenance and the effect on the eco-system will be a pain in the future. Also you will not find that many spots where you can install that thing and have water speeds of 4m/s. I think it is good as a one-off or some niche system, but it won't be very wide spread in the future. I would like to be wrong on this one though.
I've been seeing and reading about these tidal energy projects for at least 40 years. Where are all the old ones? Occasionally I'll find out that a project has 'ended.' So I'm a bit annoyed that every couple of months a shiny new one is being deployed. I think engineers have proven that you can deploy a whole range of submersible turbines and generate energy. What they don't seem able to demonstrate is that these things can keep working indefinitely in the sea. What I expect is that they get barnacles and growth on them that eventually causes so many problems the turbines can no longer turn. And yeah, I'm sure if asked these guys would talk about continual maintenance... and mean it. But what happened to their first project? Someone please compile a few dozen of these projects from the last 20 -30 years - are any still working? what were the problems? are their solutions? I know from boats that there's basically nothing that you can stick under the sea surface without stuff immediately starting to grow on it. And one project from the past year or so had two floats that went up and down with all the mechanical parts high out of the water. That might have a chance.
O2 is not exploiting the full tidal depth down to nearer seabed. Have they looked at vertical axes and tubular oriented vanes I wonder ? Repair by replacement from their vertical position ..... now where’s my Patent Application forms ;)
a prototype of anything on its own has never made money....you need investors for that to become viable as you no doubt know...i like the idea very much.....upscale it...build it and they will come
Interesting! I wonder: How will this affect the sea-life? Won't it bring nature out of balance, like wind mills are also doing with their low frequency noise?
How much energy does it take to build one of these turbines? Also, the ocean is pretty big, how come this is not the tech to help alleviate the energy crisis?
Is your attention level really that much lower than that of a gold fish that you could not pick up this information that was actually covered extensively in the video?
how many of this power generator needed to power the whole population of that country? if 1 is only enough for 2K homes, when it's in operation. It's a nice design, but what sort of environmental effect it would have with those blades? Are fishes affected? I think the sea is probably the best place to harvest energy for land use, but too many other concerns about this design and it doesn't sound very efficient.
While neat, and good to see actual ventures into harnessing tidal/wave energy, the issue with this and other 'green' power generation like solar and wind is consistency. Industry needs consistent, reliable power. You cant just run your arc furnace when the tide rolls in. However, coupled with SMR technology, a manufacturing plant or district can have a fleet of small modular reactors feeding the sites when they need lots of juice right now, then spool down as the tides, winds, and sun come out. And can be utilized to also feed the grid when the wind and waters and still and its either dark or stormy. The only issue with nuclear energy is too much of it in one place. Gigawatt single vessel reactors are a logistical problem. But smaller few tens to hundreds mega watt units can easily self shutdown, self cool (for days without coolant flow), and the rest of the fleet can take up the load of the unit that dropped out. We need every roof with solar, especially warehouses, malls, any large structure (also shading the roof and HVAC units will keep the structure cooler and allow the HVAC phase exchange cycle to run more efficiently), we need wind power, we need hydro. What we dont need is to fear nuclear, particularly in small easy to control systems. Otherwise when the wind stops blowing and the water is still its back to coal which puts out more radiation in its soot than nuclear energy has...ever. Yes, including the accidents. Sidenote: why only 2 arms? Surely they can fit at least another nacelle on there. Or two, one set of arms fore and aft of the vessel. Also, could they somehow ride the turbulent flow off of one set of blades with the down stream set? Im no hydrodynamicist, but its an interesting thought.....

If it's built in an array over a big area, will it slow down the currents? Any studies how that can effect the environment, salinity, temperature, etc.
Retrofit cargo ships to be used as battery recharging ships.
what is the power output? how could you handle bad weather? it should have that caterpillar to more it to the shore.. and a tug boat always to keep it moving.. not a negative thought but you can go for a less tiresome option?
why don't Solar Fields get made to be much higher up, like 20meters, then livestock can live under it, therefore doubling the field size
So actually how much the prototype create energy? 2000 homes x3000watt(?) = 6Mw? In 24 h. Tidal power can operate 24h right? Not like solar or wind..
And can this thing attach at ship..cruise ship, cargo ship,etc?
Of course the estimate price/cost.. to build 1Mw cost $1M or $5M..and so on..?
Tell me what in installed cost of the Scottish system? What is the cost of an O2 FOB dockside?
didnt even show it running
That looks pretty expensive to power just 2,000 homes. Things in the ocean tend not to last very long without a lot of maintenance.
Yup salt corrosion.
Maintenance costs have historically been why ocean energy projects like this haven't succeeded. The service lifetime of the generating units is too short to be worth the cost per MW. Some potential I see for this is that it would be possible to detach units and tow them to shore for overhaul, which should lower maintenance cost for them.
I still do feel that if we're looking for a strong, safe, powerful and cheap generation system, nuclear is pretty much it. Cost per MW in lives, environmental impact, materials and money is on par with or lower than any other generation technology.
@@autochton I agree some day in the future with projects like these we will develop the types of cost effective materials to mass produce and towing it to shore and lifting the blades is smart but to costly right now but i do love it I see so many wind mills sitting not running and needing maintained this requires more
Power 2000 homes WOW how many will Britain need?
Wow! Pretty awesome.
Yes its a great idea.
This thing looks amazing!
This engineering marvel generates 2 Mw which is equivalent to 3 wind turbines operating with the standard 33% capacity factor. This factor takes into account the variability of wind power. This thing would surely cost at least 100 times what 3 of your typical wind turbines cost to build. As he said, any maintenance will cost 100 times what land based work costs. I don't see the economics ever making sense.
My best wishes to Orbital. 👍
Wonder how long it’ll take to break even regarding the energy produced to make it as well as the material cost. Ocean water is harsh on materials, hope it’s resilient
nice project for engineering
Enough energy to power around 2000 homes does not sound very cost efficient to me. I like that it is clean energy, but I don't think it is very profitable.
Maintenance and the effect on the eco-system will be a pain in the future. Also you will not find that many spots where you can install that thing and have water speeds of 4m/s.
I think it is good as a one-off or some niche system, but it won't be very wide spread in the future. I would like to be wrong on this one though.
I've been seeing and reading about these tidal energy projects for at least 40 years. Where are all the old ones? Occasionally I'll find out that a project has 'ended.' So I'm a bit annoyed that every couple of months a shiny new one is being deployed. I think engineers have proven that you can deploy a whole range of submersible turbines and generate energy. What they don't seem able to demonstrate is that these things can keep working indefinitely in the sea. What I expect is that they get barnacles and growth on them that eventually causes so many problems the turbines can no longer turn. And yeah, I'm sure if asked these guys would talk about continual maintenance... and mean it. But what happened to their first project?
Someone please compile a few dozen of these projects from the last 20 -30 years - are any still working? what were the problems? are their solutions? I know from boats that there's basically nothing that you can stick under the sea surface without stuff immediately starting to grow on it. And one project from the past year or so had two floats that went up and down with all the mechanical parts high out of the water. That might have a chance.
O2 is not exploiting the full tidal depth down to nearer seabed. Have they looked at vertical axes and tubular oriented vanes I wonder ? Repair by replacement from their vertical position ..... now where’s my Patent Application forms ;)
Will this ever produce enough power to even pay for itself? I have my doubts...... But I hope I am wrong.
a prototype of anything on its own has never made money....you need investors for that to become viable as you no doubt know...i like the idea very much.....upscale it...build it and they will come
Interesting! I wonder: How will this affect the sea-life? Won't it bring nature out of balance, like wind mills are also doing with their low frequency noise?
has there been any research done into the impact it would have on marine life?
This is so freaking cool
is it animal safe. so propeller doesn’t injure animals???
I hope wind turbine don't kill those poor bird
Must be better than cars and trucks though.
No numbers available? Power, produced energy per year?
It is a Fish shredding Mashine.
Interesting, but I want to see a Greenpeace assessment of what the dead-whales-per-year will be.
interesting
The blades don't spin very fast, and whales can see and hear. So worst case scenario warning lights and sounds.
Never trust Greenpeace to make a fair assessment. They are a complete scam
How much energy does it take to build one of these turbines? Also, the ocean is pretty big, how come this is not the tech to help alleviate the energy crisis?
Underlying music was too loud in relationship to the narration
As for cost, how much was it, how many years to pay for it and how many years before it becomes profitable.
Maravillosa creación !!!
Is it possible to fit a wind turbine on top.
Awesome and hopeful!
That is really cool.
Do the blades come above the water level for maintenance? If not they’re still going to need to use divers to work on the turbine.
Surface divers can do much more work than deep divers. Much less expensive too. Sunlight will help in repairs too.
Is your attention level really that much lower than that of a gold fish that you could not pick up this information that was actually covered extensively in the video?
the big question..... efficiency ? cost / watt
how many of this power generator needed to power the whole population of that country? if 1 is only enough for 2K homes, when it's in operation.
It's a nice design, but what sort of environmental effect it would have with those blades? Are fishes affected?
I think the sea is probably the best place to harvest energy for land use, but too many other concerns about this design and it doesn't sound very efficient.
Cost of 1 complete unit. Do you suppy the technical personal or do you train local government technical staff to operate and maintain??
While neat, and good to see actual ventures into harnessing tidal/wave energy, the issue with this and other 'green' power generation like solar and wind is consistency. Industry needs consistent, reliable power. You cant just run your arc furnace when the tide rolls in. However, coupled with SMR technology, a manufacturing plant or district can have a fleet of small modular reactors feeding the sites when they need lots of juice right now, then spool down as the tides, winds, and sun come out. And can be utilized to also feed the grid when the wind and waters and still and its either dark or stormy. The only issue with nuclear energy is too much of it in one place. Gigawatt single vessel reactors are a logistical problem. But smaller few tens to hundreds mega watt units can easily self shutdown, self cool (for days without coolant flow), and the rest of the fleet can take up the load of the unit that dropped out. We need every roof with solar, especially warehouses, malls, any large structure (also shading the roof and HVAC units will keep the structure cooler and allow the HVAC phase exchange cycle to run more efficiently), we need wind power, we need hydro. What we dont need is to fear nuclear, particularly in small easy to control systems. Otherwise when the wind stops blowing and the water is still its back to coal which puts out more radiation in its soot than nuclear energy has...ever. Yes, including the accidents.
Sidenote: why only 2 arms? Surely they can fit at least another nacelle on there. Or two, one set of arms fore and aft of the vessel. Also, could they somehow ride the turbulent flow off of one set of blades with the down stream set? Im no hydrodynamicist, but its an interesting thought.....
I honestly thought this was gonna be a really cool ship
