These energy companies should hire experts from the comments section to boost their productivity
"He or she will be my friend"......what a profound statement...with engineers like this renewable energy will succeed.
I would like to see some information on the logistics of getting the electrical power from all of these floating wind generators to the consumers. In the deep water will we run cables on the ocean floor or float them below the surface a few hundred feet down? I imagine that these problems have been studied and addressed but I am interested in seeing the solutions.
They're run along the ocean floor like our fiber-optics cables. High voltage cables are really heavy.
@@kylecramer8489
Thank you, Mr. Cramer, I appreciate your response. Once again the logistics of this process elude me. I am familiar with the cables used to cross the oceans for communications and that they are very expensive. If we are going to put thousands of these windmills in deep water across the oceans we are going to need hundreds of thousands of miles of high voltage cables, since the windmills will be floating the cables will have to be miles long just to reach the floor of the ocean. Unlike communication cables which carry very little weight these high voltage cables will have to carry many tons of weight to support the long distances to the bottom of the ocean. If all the windmills have cables tethered to the ocean floor we will have to have a lot of junction boxes strategically placed to connect the individual windmills to a common cable that goes to land. I see some very difficult problems placing these junction boxes and doing all the connections necessary in water far too deep for divers. I suppose a junction box could be connected to several windmill lines on the deck of a ship and then lowered into place. The ship could then go around to the windmills and attach a cable to each mill. I was sort of hoping that the Bloomberg research people would have references to proposed methods of securing and running the cables that would allow me to read up on the process a bit, but that may be beyond the scope of this program. Thanks again for your quick response.
They will also have a floating substation that will collect power from all the turbines and transmit it onshore through an undersea cable
Why would you float them a few hundred feet down?
@@sayed5004
Having seen the North Atlantic storms I have to admit that I am skeptical of any kind of large floating system with its parts connected by long, expensive electrical cables. I noted that in the video above the admission that they were planning on the windmills moving around quite a bit since they will not be anchored in any way. If the floating substation is not anchored then the whole farm will be able to slosh around tethered only by the ocean floor cable to land. I think that all of these are solvable problems especially after seeing the natural gas line that has been run from Norway to the UK. The downside to this is that it will take a long time to bring to fruition and it will be EXPENSIVE, thus making the electricity expensive. I'm a big fan of technology but I suspect that we have run out of time where climate change is concerned.
salute to Mr. Henrik stiesdal sir, hats off you. love from india😊
Wonderful to see these bright minds designing and building energy of the future: wind and solar farms.
they lose power in transmission, they will corrode like crazy in no time flat and do you wonder how many thousands of birds will be shattered by their blades, also they're shockingly polluting to produce and they're unrecyclable, it's a joke compared to modular Fluoride Thorium salt nuke reactors, a complete joke.
Do they also develop nuclear power plants since they are the source of reliable energy for the future?
@@Veldtian1 1) All kinds of energy generation plants lose power in transmission , even modular fluoride thorium salt nuke reactors lose energy . It's a basic physics law which you can't do anything about .( And this isn't even a huge issue )
2) They won't corrode like crazy . Do normal farm wind turbines corrode due to rain ?? No they don't. BRUH .
3) These turbines are all placed in deep ocean with high winds . Birds don't fly in deep ocean . Birds move along the ocean line . BRUH .
4) Wind turbines are being produced in a large quantity since the last 100 years , never have I ever heard about them causing extreme amounts of pollution and you must also be aware that those nuke reactors you mentioned result in the production of compounds which are harmful to humans like beryllium .
5) And the last point , you said they are unrecyclable , well well you must have not done any research . Wind turbines are 90% recyclable . So you are heavily wrong here :)
@@shukrantpatil they are gonna corrode from the salt water bro
@@shukrantpatil they will probably corode like crazy. salt water is no joke.
I have a small wind powered light in my backyard. Didn't know that this guy made it!
You bought a thing humans don't necessarily need,,,
@@SAGAWISIW30 I bought a solar powered light it's useless since it only works in daylight
This is a great piece of reporting by everyone involved 👏👏. MORE PLEASE!!!
Old must meet the new to form the great.I am very impressed with the changes which are happening in engineering.
Love the precision of the clockwork and the related efficiency. Of course, wind alot more frequent off shore so no surprise.... Glad the tech is here!
hope to see that new concept get implemented in large scale!!
Many Thanks for sharing that amazing video!!
Next we can build multilevel floating wind farms to catch as much wind as possible.

Building a larger turbine is better; think of each blade as a lever, the longer the lever: the higher the torque & the great the potential energy.
@@FreeManFreeThought Think of....
- maintenance 120M above the ground w special cranes not required for 80M towers.
-parts shipped in which are too large to travel over existing roads without closing them or even modifying them
-visibility 20km away above the tree line of 300M above the ground blade tips.
Very inspiring, learnt a lot. Beuatifull system. Thank you Mr Stiesdal
You are a legend, Henrik! Thank you so much for your work!
Love the clock fascination too :)
But you have NIMBYs like the New England spending years and money preventing such projects
this is so awesome. im usually very wary of silver bullet esque solutions but this is so logical, efficient, and convenient, i am so for it. floating wind solves so many problems that comes with on-shore wind energy and just off shore wind in general. the ability to implement it in so many more places due to the irrelevancy of coastal depth is a game changer. really hope we see a floating wind boom in the next 2-3 years
Wonderful, thanks for the very usefull information.
Very true. It is all about the economies of scale to drive down per-unit cost. Politicians could learn a thing or two about this when trying to acquire defense assets.
if the wind turbine used to create compressed air and or pump water an windpark can be a lot more cost effective and has an capacitive build in to store power or wind energie indefinitely
Or purify and electrolyze water into hydrogen.
Awesome these things are revolutionary and believe they are going to change the world 🌎
Like the Hindenburg.
What I would like to see coupled with this is Wave or Tidal power tapping into the energy on or under the surface (Although there are probably engineering problems that would come from adding another complex machine to an already complex machine. Who knows what could come of industrialization and mass production of these things it could become feasible) , and underwater servers for computing. Tie this in with new and old industries on land and not only could you power the world with the energy, but you could build water desalination to end droughts. Coupling this with other mega projects and ideas you could also do things like generate water for Desert Greening in the Sahara or Australia, which would allow for not only more farms but more importantly forestry projects that would capture carbon and provide lumber for more climate friendly construction projects. Add green hydrogen production for fuel in vehicles or used in next generation cargo airships. Technology from this could even be used in off shore farms, freeing up land use. We just need the will to direct capital into these industries and a few people to take the long view.
A lot to hope for but I hope at least some of these things things come true
there are companies that can already build tidal turbines. it works, but it needs more r&d to increase the energy output.
Minesto is what you are looking for.
Thanks for posting
Fascinating discussion on the evolution of wind turbines.
Very challenging, but we must try our best, because the Earth's CO2 and the pollution are on the catastrophic path.
But:
Solar power in the center of the Sahara is and could not be productive, we already know that, but maybe in 10 or 20 years who know, we must keep trying...
Deep water wind turbines also very challenging - high maintenance costs, higher rust, high power losses due to bigger distance from consumers, but we must keep trying ...
Tidal turbines/dams, the same.
Nuclear power, very challenging.
Fossil fuel very polluting.
But we have to keep trying our best!
thanks for the great reporting! it is inspiring to see all these great minds at work...oil and gas companies using their expertise and capabilities to employ wind to power their rig operations is such an incredible and sensible transition!
I love these Bloomberg Quicktakes
This is actually a positive outlook news item. I feel reassured 👍👍🏴🏴
I love that guy's apartment
Archeological traces and antic soil underwater can help us learn so much. The past lightens the future to live our present better
Orsted is also doing great job in its international strategy and foreign investment.
at 02:17 , the power equation he is trying to explain is Power=(1/2) Rho (V^3) (Pi R^2). What in the video is incorrect.
I'll put all my money into vestas
Why not SeaTwirl? Vestas maket cap is 1300 times SeaTwirl's but SeaTwirl's floating offshore wind turbine technology is much more cost effective. Imagine the potential if you invest in SeaTwirl instead.
Fascinating! But I live in Southern California and these guys were talking bout how deep our ocean is and how great a floating wind farm would be in such waters, but this is also earthquake country and I heard nothing about these turbines standing up to tsunamis… I’d be interested to hear their thoughts on that.
Interesting point. If they're far out then they'll be on the swell, I'd imagine. I've always assumed the wave only breaks steep enough to push things along when it gets to a shallower region.
I may be wrong but I thought that tsunamis didn’t change the elevation of the ocean in deeper areas , they only became problematic when pushing that extra water upon the beaches and intertidal areas. If I am wrong I am sure someone will point this out to me.
When did you last have a tsunami in Southern California?
@@martin3203 lol🤣
Tsunamis are not really higher than normal waves in deep waters. So no problem there
Hello, I would like to understand the opportunity and challenge to anchor and exploit deep water turbines implementing deep water, single anchor fixation.
Great Art Explained
Trouble with wind power is that it runs out of "puff" - inconvenient. I've got a big wood shed. Cheers Stuart
Might as well adapt the floating structure and install a turbine to generate power from wave energy.
mare, while your concern is understandable current sources pertaining to the energy generation (coal, petroleum, solar, etc.) are also generally not located within close proximities to the consumer and therefore the distribution relies on significant wire runs to the grid as will the off shore wind turbines. The remote locations will incur more disapportionate costs like the existing more remote sources.
Brilliant 👌
In one word, a legendary pioneer!
I hope to see this technology hit home soon
Yep and your life will have to become about 75% more energy efficient too, I'm sure you'll love to only be able to travel as far in your entire life as the full charge on your electric scooter.
@@Veldtian1
You do understand that your point entirely relies on the assumption that nobody will be able to come up with more efficient electronic devices in the future, right? It's not like these things have been around for thousands of years and there's no ideas left to come up with for it. You know what I'm gonna eat next Tuesday too?
@@Veldtian1 You must have a nice horse and buggy. That automobile thing will never take off. You spend more time fixing them than driving after all XD
Same challenges as with tidal power (this has been looked at for over 50 years, there's a reason its not done): (a) Stability and reliability of tethering in the event of very bad weather (b) power cables over such vast distances lose a lot of power, are impractical to implement and also prone to breakage in bad weather, and become very very expensive (lots or copper required). (c) Maintainabliity and repair when things inevitably break. If you want to save the planet, nuclear power is the way. Theres plenty of research on transmutation of waste to less radioactive isotopes. Yes I'm a physicist.
Dude Henrik Stiesdal is todays Tesla
This is amazing.
Wonderful video! I just read about floating wind turbines two weeks ago, so very happy to get the chance to go deeper with your video!
Have a look at SeaTwirl.
What a time to be alive! Thanks a lot @@Patrick-ws7nz!
Interesting, but what are they gunna do about the sand blasting effects of the ocean salts on the turbines? They'll probably have to replace those blades every 3 to 5 years if they are fiberglass resin composites. Hope they keepin tat in mind and budget.
I wonder if some of these offshore oil rigs might be better used as wind turbine bases instead of being either left abandoned or dismantled and scraped...?
Many of them are pretty far from shore, and it will probably be a few decades before we actually need to go very far from the shoreline
Your idea isn't bad, but I'd think the number of adaptable drilling rigs and platforms is pretty small. A bigger problem is that adapting them for wind power production would be so expensive that it probably wouldn't make economical sense. As Henrik Stiesdal says on the video, large scale and big series are the key for cheap production. Oil platforms tend to be different from each other, so you would have to do a lot of tailoring, which is expensive. You'd also have to tailor the maintenance, which would add to the cost too.
The most interesting green energy information I've ever seen
Storage and transmission are the keys
They should also add wave energy generators to these to double up the use of space
Great vid
Even floating wind turbines are obsolete, intermittent and expensive in installation/maintenance. Tar Kovacs Systems offshore self-contained plants are exploiting three or four ocean simultaneous power sources without installation work, very low maintenance, producing CONSTANT power or Green Hydrogen, and is increasing/controling each in any weather conditions. No water depth consideration. 100 to 600MW per unit 24/7/365 every where on the oceans.
This is amazing, but, also we need to find storage solutions side by side with a rapid deployability
You don't need much storage with offshore wind and intrrconnectors
People imagine the wind is like their back yard. The wind resources in the North Sea are some of the best on the planet. More than half the time there is a wind speed in excess of 20mph
Me pregunto porque no se utilizan conjuntamente la energía eólica offshore en forma híbrida con la undimotriz. Con algo más de costo inicial, del aerogenerador la producción energética puede aumentar de forma considerable utilizando menos espacio marino aparte de otros beneficios que aportaría la utilización conjunta de ambas energías.
Awesome video

can offshore wind be merged with tidal power by interconnecting many turbines that have a wind turbine on top and a tidal turbine below the surface ...
tidal works best in shallow-ish waters, floating wind turbines are for deep seas. you can connect the two, but they don't have to be. it's fine working them separately.
You put dragons from Minesto below the surface
This is great. :)
This makes sense but so does geothermal which is not used enough!!
Geothermal can’t be used more because suitable close to the surface hot rock is rare, success rate of drilling expensive homes is rare, and geo releases a lot of CO2 from carbon bearing rock, occasionally more than burning coal.
Awesome.
We need thede now!!
I love this!
This makes me very happy in an otherwise hopeless world
Bloomberg needs to talk about Ecosia they are a search engine that plants tress
Cost of transportation of the electricity to land and loss of current due to resistance?
Why don't they put a water turbine below it as well to generate electricity from water currents too. Make it dual use.
Because of the salt in the water wears down the moving parts + lack of efficiency and scale from the current tech in that area in general
honeycomb aluminium blades are cheap, strong and recyclable
-the wind always blows off-shore and under-sea cables are cheap and easy
Amazing
Den tykke danske accent. Den gør mig så glad
what happens to all the fiberglass when these deteriorate?
so how do deep sea wind power plants transit power generated from deep sea to the grid?
umm can someone help me here, does the narator say "spa principle" at 10:49? I can't quite catch that. Thanks!
"Spar"
@@afederdk Thank you so much!!
Since the floaters need big underwater structures anyway it might be economically viable to store some energy by removing the water down there when needed.
Why store energy offshore, when you can store it onshore. Also changing a damaged battery underwater, is more economically robust than simply leaving the water there. Lol
@@CADPond Pressure tanks& turbines, no batteries:)
Could duch facilities come up in the Arabian sea off the coast of i ndia, to discourage and avoid coal combustion?
Anti-roll gyro must be employed in floating wind turbines to stabilize them in rough seas with strong wind .
Anti-roll gyro enables floating wind turbine to harness wind energy in rough seas.
I wonder if you'd have to have a caretaker crew that lives out there for periods of time to repair the turbines if something goes wrong in the same way that crews live on oil platforms. If they are so far out to sea and a gyro goes bad, I imagine that's a pretty significant investment to lose because you couldn't get there in time to fix it before it sank
High temperature Superconducting wind turbine generator makes floating wind turbine more efficient , due to higher energy density.
Furthermore, predictive Ai enabled IOT system could reduce maintenance cost.
question: looks like the generator is near the top making the center of gravity of this structure high making it easier to 'pitch'(lean backwards) due to wind forces. placing the generator lower and driving it through some sort of drive train would lower the center of gravity, allowing wind to turn the blades (instead of causing the structure to lean backwards) and allow it to capture wind energy more efficiently.. so what is the advantage of placing the generator up high?
Higher wind speeds the taller they build them was the reason they gave I think. But yeah, I get what your saying. I assume the top can turn so the blades are always facing into the wind, so maybe they can also tilt back and forth a little to counter act the effect and keep the top level and the blades at the right angle of attack to catch the wind efficiently. Not sure though, just a guess 🤷♂🙂
You add ballast to the base structure to mitigate
that would increase the total weight of the structure. now we need more buoyancy to float. moving existing mass (generator) downwards would probably be more advantageous compared to adding ballast.
The people in the video are not building wind turbines. They are building the structures for offshore floating turbines.
And since it's in the test phase, they use regular wind turbines.
It would be very expensive, just to build special wind turbines for this purpose.
vertical axis wind turbines exist, and they have some advantages compared to horizontal axis wind turbines, although I'm not sure anyone has a large scale commercial turbine of this kind.
irl, manufacturers like Siemens and Vestas want as few mechanical moving parts as possible because they are the first thing that breaks in wind turbines. so, adding yet another drive train/gears would probably be a big no-no for them.
p.s. check direct drive wind turbines.
*_How much fuel do they burn out to produce one of this "clean" turbine ???_*
This has actually been extensively researched and written about in professional spaces and it its actually pretty negligible considering that construction, placement and maintenance are really the only times it creates emissions, and they often go 25 years without needing much maintenance at all, on average they emit between 5 and 25 grams of carbon when coal and natural gas would produce from 100 grams to 870 for the same amount of energy, averaged over the lifetime of the turbines. Everything costs something and when it's a choice between continuing use of fossil fuels (which'll run out eventually and destabilize the climate we rely on for the ability to breathe and eat and whatnot long before that), or we do something to avoid mass suffering in the future when we can before it gets worse, I'd rather take the latter, but maybe that's just me.
Also there's this new thing called google, you just type just about any question and easily find lots of people educated on the subject talking about it as well as most scientific papers from the last few centuries to present. It's crazy, I know but you can educate yourself before spreading misinformation and everyone benefits.
Well we made the Mosquito plane out of wood in just the same way. It was the envy of the Luftwaffe. There are fewer problems with disposal compared to steel sections maybe? And yes it locks up CO2.
Which are the best publicly traded companies active in this field?
Vestas, Siemens Gamesa, Goldwind to mention a few.
ørsted as well
In emerging markets like India, government pushing big on green energy. Solar stock have gone 5 times like Tata Power, I wonder how Suzlon,a wind turbine company trading at 10 rupees 🤣 cost of a cigarette
@@ctcfinacialservices Suzlon was Indian wind pioneer and made a lot money initially. But later entry of international competitors like GE, Vestas and Siemen Gamesa with superior wind turbines made them go out of business. Though Suzlon has undergone debt restructuring, Vestas will remain the market leader followed by Gamesa.
Seatwirl has the most cost effective solution by far for floating offshore wind. Totally designed for sea conditions from the very beginning and with a very low center of gravity. Also easy and hence cheap to service since all parts that might need replacement are near sea level. Traded at Nasdaq First North.

They should cover the blades with photovoltaic cells.
5:52 either a very old map of Europe or Poland has been partitioned again
Indonesia is a country with the largest ocean and 17,504 islands, hopefully in the future this technology can save small islands in Indonesia
And nobody mentions Denmark?
Cylinder turbines would be much better. Tidal generators even more.
The wind farm developers make all the money in this industry. The wind turbine manufacturers barely make any money.
What's different between vortical or horizontal turbine
It refers to the orientation of the shaft. For example, the traditional three blades turbines are horizontal axis wind turbines.
Seatwirl sells Vertical Axis Wind Turbines (VAWT) for floating offshore wind. Check them out.
Yes!
A capacity factor is the ratio of the power output to the power capacity. So the 57% that is lauded by the Statoil rep in this video would be a laughably small number for a nuclear power plant or a hydrogen burning plant.
And why does it matter? You can build it for a lot cheaper, so you can build more of them in more areas that make up for it, and you'd have higher total output (during those peaks you fill up hydro storage, be it dams, or everyone talking about new hydrogen tech, or cheap home usage systems, allow people to heat up another 2C during that peak time, or allow people to schedule stuff like washing machines, etc.).
Also he was talking about being at max capacity, not not outputting power, looking up danish figures for offshore, their min seems to be about 40% of nameplate capacity for 2018/19, which is one of the worst years in the last decade.
How can they deliver the power to the consumers taking into consideration the loss of voltage due to increase in resistance?
Stepping up... Higher voltages lower losses
"The energy the wind turbines produce will help power the companies oil and gas platforms." ehh...
this is probably the best solution to the twin problems of power and clean water the US west will have...will need to desalinate large volumes of seawater in 50 years time.
Another interesting question will be, how long the life cycle of such turbines can be, what amount of servicing they will need to keep them in operating conditions, and what will happen to them, when they passed their duty.
offshore wind turbines already exist and produce electricity, they have a lifetime of about 20-25 years depending on service contracts. at end of life they're disassembled, the metals in them are too expensive to throw them away.
My understanding is they become land fill.
You've got to love the competition between the "godfather of wind" sitting in front of his clocks, just out of retirement, up against the multi billion dollar behemoth Equinor. Wouldn't be surprised if the godfather has some tricks up his sleeves 😁

Why would it be a scam? It's all based on wellknown technology and physical principles.
We'll Need new workers to do maintenance and repairs to these machines like all machines humans make/build. Also the workers thatll be needed for placing them into the oceans/seas and then dismantling of such at the end of life of these machines.
Or you use workers from the O&G and field, like myself and others have done.

How about Tidal turbine for electricity ?
