North Sea Wind Power Hub
I have just found the web site for the North Sea Wind Power Hub.
The Aim
This introductory paragraph details the aim of the project.
A coordinated roll-out of North Sea Wind Power Hubs facilitates an accelerated deployment of large scale offshore wind in the North Sea required to support realizing the Paris Agreements target in time, with minimum environmental impact and at the lowest cost for society (urgency & cost savings), while maintaining security of supply.
There is a lot to read on the site, however this article on the Daily Mail gives a good summary with lots of drsawings.
This is the sub-headline.
The world’s biggest wind farm? ‘Crazy’ artificial power island in the North Sea that could supply renewable energy to 80 million people in Europe is set to open in 2027.
Crazy comes from this paragraph of the article.
In an interview at the time, Torben Glar Nielsen, Energinet’s technical director, told the Independent: ‘Maybe it sounds a bit crazy and science fiction-like but an island on Dogger Bank could make the wind power of the future a lot cheaper and more effective.’
Another quote sums up the engineering problems as the Dutch sea it.
Addressing the engineering challenge ahead, Mr Van der Hage said: ‘Is it difficult? In the Netherlands, when we see a piece of water we want to build islands or land. We’ve been doing that for centuries. That is not the biggest challenge.’
Having spoken to one of the engineers, who planned and developed the Dutch sea defences after the floods of the 1950s, I’ll agree with that statement.
Nuclear Option Has Been Blown Away
The title of this post is the main title of Alistair Osborne’s Business Commentary of today’s copy of The Times.
He is referring to the government’s announcement about new wind farms, that I discussed in Climate change: Offshore Wind Expands At Record Low Price.
I particularly liked his final paragraph.
And nuclear’s not even green: it comes with a vast clean-up bill. True, it brings baseload energy that wind can’t yet match. But storage technology is advancing all the time. So why’s the government persisting with last century tech that comes at a radioactive price? Yes, offshore wind might endanger a seabird that’s forgotten its specs. But, luckily, it’s a bigger threat to another species: nuclear white elephants.
Climate change is so serious, people won’t believe it’s happening and take action unless the medicine is delivered with a spoonful of humour.
Climate change: Offshore Wind Expands At Record Low Price
The title of this post, is the same as that of this article on BBC News.
These are the first paragraphs.
A record amount of new offshore wind power has been announced in the UK – at record low prices.
The new projects will power more than seven million homes for as little as £39.65 per megawatt hour.
Compare this price with the £92.50 per MWh for the nuclear Hinckley Point C.
Note that all prices are in 2012 prices.
I have no argument with the engineering of nuclear power stations, but they do have issues that must be addressed.
- They shouldn’t be built in possible earthquake zones.
- They have a very high cost.
- They can be an eyesore in parts of the UK.
But they do provide a good power zero-carbon baseload, once they are constructed.
Dogger Bank Wind Farm
The Dogger Bank Wind Farm would appear to be the centrepiece of the energy developments South of the Scottish Border.
It will be three separate 1.2 gigawatt wind farms developed on the relatively shallow seas around the Dogger Bank.
- Creyke Beck A
- Creyke Beck B
- Teesside A
Wikipedia says this about the first two wind farms.
They would connect to the existing Creyke Beck substation near Cottingham, in the East Riding of Yorkshire.[6] The two sites lie 131 kilometres (81 mi) from the East Yorkshire coast.
Both have an area of around two hundred square miles.
Teeside A is further North and would be connected to a substation near Redcar.
North Sea Wind Power Hub
The three fields I’ve listed are all in UK waters and according to Wikipedia will or could be joined by more wind farms in the same area.
But just across the maritime border between the United Kingdom and the European Union, Denmark, Germany and The Netherlands have plans to develop the North Sea Wind Power Hub.
Wikipedia introduces the project like this.
North Sea Wind Power Hub is a proposed energy island complex to be built in the middle of the North Sea as part of a European system for sustainable electricity. One or more “Power Link” artificial islands will be created at the northeast end of the Dogger Bank, a relatively shallow area in the North Sea, just outside the continental shelf of the United Kingdom and near the point where the borders between the territorial waters of Netherlands, Germany, and Denmark come together. Dutch, German, and Danish electrical grid operators are cooperating in this project to help develop a cluster of offshore wind parks with a capacity of several gigawatts, with interconnections to the North Sea countries. Undersea cables will make international trade in electricity possible.
These points are also made.
- Six square mile islands will be built surrounded by thousands of wind turbines.
- The Dutch have estimated that 110 gigawatts of wind power could be produced at the Dogger Bank location.
- We are not a member of the consortium, but it is hoped that Norway, Belgium and the UK will join.
- The Dutch have suggested converting some of the electricity produced to hydrogen.
- Completion date is set for 2050.
I am excited by this project.
We may not be part of the North Sea Wind Power Hub consortium and in a month or so, we may or may not be part of the European Union, but today’s announcement of new wind power projects in our section of the Dogger Bank is effectively a substantial marker, that compliments the European plan.
Consider.
- We are putting 3.6 GW of wind turbines on the Dogger Bank.
- We are connecting it to the UK electricity grid. at Creyke Beck.
- It would be easy to create another bi-directional electricity interconnector between the UK’s planned and the EU’s possible wind farms.
This is the sort of project that works, whether Brexit happens or doesn’t!
Six Scottish Wind Farms
.There is also a second article on the BBC, which is entitled Six Scottish Wind Farms Awarded Contracts.
These are the first paragraphs.
Six Scottish wind farm projects are set to go ahead after being awarded UK government contracts to sell the electricity they would produce.
The schemes include Forthwind and SSE Renewables’ Seagreen Phase 1, which are both proposed for the Firth of Forth.
Four onshore wind farms – Muaitheabhal and Druim Leathann in Lewis and Hesta Head and Costa Head in Orkney – have also secured contracts.
All farms are expected to be built by 2025 and provide enough energy for 265,000 homes.
Price Summary For Offshore Wind
This page on Offshore Wind gives the strike prices for the six offshore wind farms.
Creyke Bank A – £39.65 per MWh – 1200 MW
Creyke Bank B – £41.61 per MWh – 1200 MW
Teeside A – £41.61 per MWh – 1200 MW
Teeside B (Sophia) – £41.65 per MWh – 1400 MW
Forthwind – £39.65 per MWh – 12 MW
Seagreen Phase 1 – £41.61 per MWh – 454 MW
The size of each farm is also given.
Conclusion
The lights will stay on and we will need to develop more energy storage.
Government Turns Up Power On Offshore Wind
The title of this post, is the same as that of an article in yesterday’s copy of The Times.
This is the first paragraph.
A third of British electricity will be generated by offshore wind farms by 2030 under government plans.
Although Jeremy Corbyn said he would reopen coal mines a couple of years ago, I can’t see a change of Government stopping this.
A few other points from the article.
- Last year offshore wind produced about eight percent of our electricity needs.
- The offshore wind energy industry has said it will raise UK content from 48 to 60 percent.
- The industry has promised to invest £250million in the supply chain.
- There are 1,900 turbines in British waters, which can generate 8GW.
- Another 6GW will come on stream by 2022-23.
- Another 16GW are in the planning stage.
The author feels that as costs are reducing, this is driving the investment.
Conclusion
We have a very windy future.
The Old Order Changeth Yielding Place To New
Two dinosaurs; the Labour Party and the motor industry, got big shocks yesterday.
But both are trying to live in the past with CEOs, who still think that we’re in the 1960s.
This morning, my message read out on Wake Up To Money was this.
I don’t drive any more, but the future is electric and the UK is blessed with a position and a climate to become one of the first countries to power most vehicles with renewables. Vehicle manufacturers must change or die!
Our renewable electricity generation infrastructure is growing apace and in the last few days, the world’s largest offshore wind farm opened, as reported in this article on the BBC, which is entitled First Power From World’s Biggest Offshore Wind Farm.
The Hornsea Wind Farm will have a generating capacity of 6 GW. This is nearly twice as large a capacity as the troubled Hinckley Point C nuclear power station.
But whereas Hinckley Point C will produce continuous power, Hornsea will only produce power when the wind blows.
The National Grid are tasked with keeping the lights on and I agree with them, that energy storage is the solution.
- There are 25,000,000 homes in the UK. If every house in the UK was fitted with a 10 kWh storage battery, that would be a capacity of 250 GWH.
- There are 30,000,000 cars in the UK. If every car in the UK was electric and had a 30 kWh battery, that would be a capacity of 900 GWH.
These are very large numbers and just as the Internet passes data all around the UK and the world, the UK’s National Grid will access all these batteries to store energy, when perhaps the wind is blowing at night and retrieve it when there is a high demand.
On a domestic level, you may have an electric car and a battery in your house, with perhaps solar panels on the roof.
- At night and on sunny days, your batteries will be charged.
- At times of high demand, your stored energy may be sold back to the grid.
- Controlling it all would be an intelligent computer system, which would make sure that your car always had enough charge and you had enough energy for the house.
The problem is that nearly all of our houses and cars don’t fit this model.
The proposed closure of the Honda plant is Swindon, is the first of the many casualties in car manufacturing, that will surely happen.
More by luck, than judgement, when I moved to London after my stroke, I bought a house with the following features.
- Low energy consumption.
- A flat roof, that is now covered in solar panels.
- A garage, that would be suitable for an electric car. Although, I don’t drive, the next owner of this house, probably will.
Millions of houses in this country should be demolished and the land used for new houses that fit the modern age.
The Labour Party is living in the 1960s and Corbyn and McDonell still believe that the Robin Hood approach of stealing from the rich and giving it to the poor, is still the way to go.
But these days, most people want to be responsible for themselves. This is why there has been such a growth in people in the gig economy like Uber, Deliveroo and County Lines.
Everybody wants to take control of their lives and their own micro-economy. That is why I left a safe job at ICI in 1969, at the age of just twenty-two.
Like me, those who start their own successful business don’t want government to come along and use it on pet projects that always seem to fail.
Most politicians and especially Labour ones have never done a real job in their lives and Labour’s defections will hopefully be the first of many from all political parties.
I hope that February 18th 2019, will be remembered as the day when two dinosaurs realised they needed to change their spots.
But they won’t change willingly!
However!
- Companies and individuals will soon be buying electric vehicles in large numbers and only buying diesel and petrol ones, where there is no alternative.
- Voters will not vote for policies that stink of the past, that don’t fit their micro-economy.
There will also be a lot of unsaleable houses and second-hand cars!
World’s Largest Wind Farm Attracts Huge Backing From Insurance Giant
The title of this post, is the same as that of an article in the Business pages of yesterday’s copy of The Times.
It is not often that three words implying something big appear in the same sentence, let alone a headline! Such repetition would more likely appear in a tabloid to describe something sleazy.
Until recently, wind power was just something used by those in remote places. I remember a lady in Suffolk, who had her own turbine in the 1980s. She certainly lived well, although her deep freeze was in the next door farmer’s barn.
Now, with the building of the world’s largest wind farm; Hornsea, which is sixty miles off the coast of East Yorkshire, wind farms are talked of as creating enough energy for millions of homes.
Hornsea Project 1 is the first phase and Wikipedia says this about the turbines.
In mid 2015 DONG selected Siemens Wind Power 7 MW turbines with 154 metres (505 ft) rotor turbines for the project – around 171 turbines would be used for the wind farm.
Note that the iconic Bankside power station, that is now the Tate Modern had a capacity of 300 MW, so when the wind is blowing Hornsea Project 1 is almost four times as large.
When fully developed around 2025, the nameplate capacity will be around 6,000 MW or 6 GW.
The Times article says this about the funding of wind farms.
Wind farms throw off “long-term boring, stable cashflows”, Mr. Murphy said, which was perfect to match Aviva policyholders and annuitants, the ultimate backers of the project. Aviva has bought fixed-rate and inflation-linked bonds, issued by the project. While the coupon paid on the 15-year bonds, has not been disclosed, similar risk projects typically pay an interest rate of about 3 per cent pm their bonds. Projects typically are structured at about 30 per cent equity and 70 per cent debt.
Darryl Murphy is Aviva’s head of infrastructure debt. The article also says, that Aviva will have a billion pounds invested in wind farms by the end of the year.
Call me naive, but I can’t see a loser in all this!
- Certainly, the UK gets a lot of zero-carbon renewable energy.
- Aviva’s pensioners get good, safe pensions.
- Turbines and foundations are built at places like Hull and Billingham, which sustains jobs.
- The need for onshore wind turbines is reduced.
- Coal power stations can be closed.
The North Sea just keeps on giving.
- For centuries it has been fish.
- Since the 1960s, it has been gas.
- And then there was oil.
- Now, we’re reaping the wind.
In the future, there could be even more wind farms like Hornsea.
Ease Of Funding
Large insurance companies and investment funds will continue to fund wind farms, to give their investors and pensioners a return.
Would Aviva be so happy to fund a large nuclear power station?
Large Scale Energy Storage
The one missing piece of the jigsaw is large scale energy storage.
I suspect that spare power could be used to do something useful, that could later be turned into energy.
- Hydrogen could be created by electrolysis for use in transport or gas grids.
- Aluminium could be smelted, for either use as a metal or burnt in a power station to produce zero-carbon electricity.
- Twenty-four hour processes, that use a lot of electricity, could be built to use wind power and perhaps a small modular nuclear reactor.
- Ice could be created, which can be used to increase the efficiency of large gas-turbine power plants.
- Unfortunately, we’re not a country blessed with mountains, where more Electric Mountains can be built.
- Electricity will be increasingly exchanged with countries like Belgium, France, Germany, Iceland, Norway and The Netherlands.
There will be other wacky ideas, that will be able to store GWhs of electricity.
These are not wacky.
Storage In Electric Vehicles
Consider that there are three million vehicles in the UK. Suppose half of these were electric or plug-in hybrid and had an average battery size of 50 kWh.
This would be a total energy storage of 75,000 MWh or 75 GWh. It would take the fully developed 6GW Hornsea wind far over twelve hours to charge them all working at full power.
Storage In Electric And Hybrid Buses
London has around 8,500 buses, many of which are hybrid and some of electric.
If each has a 50 kWh batttery, then that is 425 MWh or .0.425 GWH. If all buses in the UK were electric or plug-in hybrid, how much overnight electricity could they consume.
Scaling up from London to the whole country, would certainly be a number of GWhs.
Storage In Electric Trains
I also believe that the average electric train in a decade or so could have a sizeable battery in each coach.
If we take Bombardier they have an order book of over four hundred Aventra trains, which is a total of nearly 2,500 coaches.
If each coach has an average battery size of 50 kWh, then that is 125 MWh or 0.125 GWh.
When you consider than Vivarail’s two-car Class 230 train has a battery capacity of 400 kWh, if the UK train fleet contains a high-proportion of battery-electric trains, they will be a valuable energy storage resource.
Storage in Housing, Offices and Other Buildings
For a start there are twenty-five million housing units in the UK.
If just half of these had a 10 kWh battery storage system like a Tesla Powerwall, this would be a storage capacity of 125 GWh.
I suspect, just as we are seeing vehicles and trains getting more efficient in their use of electricity, we will see buildings constructed to use less grid electricity and gas.
- Roofs will have solar panels.
- Insulation levels will be high.
- Heating may use devices like ground source heat pumps.
- Battery and capacitors will be used to store electricity and provide emergency back up.
- Electric vehicles will be connected into the network.
- The system will sell electricity back to the grid, as required.
Will anybody want to live in a traditional house, that can’t be updated to take part in the energy revolution?
Will The Electricity Grid Be Able To Cope?
National Grid have been reported as looking into the problems that will happen in the future.
- Intermittent power from increasing numbers of wind and solar farms.
- Charging all those electric vehicles.
- Controlling all of that distributed storage in buildings and vehicles.
- Maintaining uninterrupted power to high energy users.
- Managing power flows into and out of the UK on the various interconnectors.
It will be just like an Internet of electricity.
And it will be Europe-wide! and possibly further afield.
Conclusion
The UK will have an interesting future as far as electricity is concerned.
Those that join it like Aviva and people who live in modern, energy efficient houses will do well.
The Wind Of Change Blowing All Over The UK
This has nothibg to do with Brexit or even politics, but the UK and in addition our friends in Denmark, Germany, Ireland and The Netherlands seem to be investing to reap the wind.
To many of my generation, Hornsea is a town on the Yorkshire coast famous for dull ethnic pottery. But now it will the name of the Hornsea Wind Farm, which will have a generating capacity of up to 4 GigaWatt or 4,000,000 KiloWatt. It will be sited around 40 kilomwtres from the nearest land.
To put the size into context, Hinckley Point C, if it is ever built will have a power output of 3.2 GigaWatt.
You may day that wind is unreliable, but then Hornsea will be just one of several large offshore wind farms in the UK.
- Dogger Bank(4.8 GW),
- Greater Gabbard(504 MW)
- Gwynt Y Mor(576 MW)
- London Array(630 MW)
- Race Bank(530MW
- Thanet(300 MW)
- Yriton Knoll(600-900 MW)
- Walney Extension (659 MW).
The electricity produced can be used, stored or exported.
Storage will always be difficult, but then there are energy consumptive industries like aluminium smelting, creating steel from scrap or the electrolysis of water to produce hydrogen, oxygen and ither gases, that could probably be based around an interruptible supply backed-up by a biomass or natural gas power station.
Hydrogen As A Fuel
Hydrogen could be the fuel of the cities for buses, taxis and delivery vehicles. Suppose they were hybrid, but instead of a small diesel engine to xharge the battery, a small hydrogen engine or fuel cell were to be used.
Remember that the only product of burning hydrogen is water and it wouldn’t produce any pollution.
Each bus garage or hydrogen station could generate its own hydrogen, probably venting the oxygen.
Enriched Natural Gas
We can’t generate too much hydrogen and if because of high winds, we have hydrogen to spare it can be mixed with natural gas, ehich contains a proportion of hydrogen anyway.
Scotland’s Floating Wind Farm
This article on the BBC is entitled World’s first floating wind farm emerges off coast of Scotland.
In the early 1970s, I worked on a unique concept for a reusable oil platform called a Balaena.
I wrote about using a Balaena for a wind turbine in Could a Balaena-Like Structure Be Used As a Wind Power Platform?.
There is also a brief description of the idea in The Balaena Lives.
I have a strong feeling that revisiting all of the work done for a Balaena over forty years ago, could enable a better way to build a floating wind farm.
I would build my Baleana-based floating wind-power turbine like this.
- A steel cylinder is built, which will form the tower, horizontally in a dry dock.
- It is floated out horizontally to some very deep water perhaps in a fjord.
- It is then raised to a vertical position by letting a calculated amount of sea water into the tank.
- It will float vertically, if the weight profile is right and by adjusting water levels in the tank, the top can be raised on lowered.
- The tower is adjusted to a convenient height and the turbine is placed on the top.
- It would then be towed vertically into position.
Note that Balaenas were designed to sit on the sea-bed using a skirt and a gum-boot principle to hold them to the bottom, with extra anchors and steel ropes.
Are Wind Turbines Not What They’re Cracked Up To Be?
The news this morning that RWE Innogy are not going ahead with the Atlantic Array of 240 wind turbines is to some surprising.
The developers cite engineering difficulties and that it is not the right time for the project, although others are saying that there are financial problems with the project.
If we are going to have wind turbines, which I’ll admit, I think are an eyesore in the British landscape, then offshore is probably the best place for them.
I think that this array might well be built at some time, but only after new and better technology has arrived.
It would be wrong to increase the subsidy for the project to get it built.
If subsidies go anywhere they should go into energy research.
1. We should try to find better ways of getting the gas out that is there, that would otherwise use crude fracking techniques.
2. Our buildings are notoriously badly insulated and research should be directed to find better ways of cutting energy use.
3. Research could also be directed towards better ways of generating heat and power, to widen some of the techniques used at places like the Bunhill Energy Centre.
Just using subsidies to put up wind turbines, is like giving an alcoholic or drug addict, money to fund their habit. It might give some a good feeling, but it does nothing for the overall good of society.
Could a Balaena-Like Structure Be Used As a Wind Power Platform?
Last night I was watching reports on the BBC about the Ormonde Offshore Wind Farm.
Again, I can’t help thinking that a Balaena like structure could be used. It would be tall and thin and the wind-turbine could just be lifted onto the top.
It would be built in a shipyard horizontally and would have a steel tank at the bottom to give it stability. As with the original Balaena weight and the gum-boot syndrome would keep it in place.
It would also be towed out horizontally and then upended by filling the tank. I proved that this would work nearly forty years ago and I’m sure if you get the sizes right, it would be very stable. You then just lift the power unit on the top in the normal way.
But then I’m no structural engineer. On the other I have a memory like an elephant and never forget anything useful.
Where is Buckminster Fuller when you need him?
