Keadby 3 Low-Carbon Power Station
This article on Business Live is entitled Huge Green Power Station Proposed By SSE As It Embraces Hydrogen And Carbon Capture.
SSE Thermal is working on a low-carbon 910 MW gas-fired power station to join Keadby and Keadby 2 power stations in a cluster near Scunthorpe.
A spokesman for SSE is quoted as saying they will not build the plant without a clear route to decarbonisation.
On this page of their web site, SSE Thermal, say this about Keadby 3.
As part of our commitment to a net zero emissions future, Keadby 3 will only be built with a clear route to decarbonisation, either using hydrogen as a low-carbon fuel, or equipping it with post-combustion carbon capture technology. The project is at the early stages of development and no final investment decision has been made.
It should also be noted that SSE Renewables have also built a wind farm at Keadby. The web site describes it like this.
Keadby Wind Farm is England’s largest onshore wind farm. This 68MW renewable energy generation site can power approximately 57,000 homes.
There are a lot of good intentions here and I think that SSE haven’t disclosed the full picture.
It would seem inefficient to use hydrogen to power a gas-fired power station to achieve zero-carbon power generation.
- If you are using hydrogen created from steam reforming of methane, this creates a lot of carbon-dioxide.
- If you are using green hydrogen produced by electrolysis, then, why don’t you store the electricity in a battery?
Perhaps, SSE are trying out a new process?
This Google Map shows the area of Keadby to the West of Scunthorpe.
Note.
- The River Trent meandering through the area.
- Althorpe station is in the bend of the River,
- I’m fairly certain, that I remember an old airfield in the area.
- Keadby power station is a bit to the North of the waterway running West from the River and close to where the railway crosses the waterway.
This second Google Map shows a close-up of the power station.
This visualisation from SSE Thermal shows how the site might look in the future.
For me the interesting location is the village of Althorpe, where C and myself had friends.
They were always getting tourists arriving in the village looking for Princess Diana’s grave!
Carbon Capture And Storage At Keadby
If SSE have three large power stations at Keadby, a shared carbon capture and storage system could be worthwhile.
- There are numerous gas fields in the area and a big gas terminal at Theddlethorpe, to where they all connect.
- I was surprised to see, that one of thee fields; Saltfleetby is owned by President Putin’s favourite gas company; Gazprom.
- Some of these fields are actually on-shore.
- The power stations probably get their gas from the same terminal.
Some of these gas fields that connect to Theddlethorpe could be suitable for storing the carbon dioxide.
As there is masses of space at Keadby, I can see more gas-fired power stations being built at Keadby.
All would feed into the same carbon capture and storage system.
If gas was needed to be imported in a liquified form, there is the Port of Immingham nearby.
Absorption Of Carbon Dioxide By Horticulture
Consider.
- Increasingly, horticulture is getting more automated and efficient.
- Automatic harvesters are being developed for crops like tomatoes and strawberries.
- Instead of storing the carbon-dioxide in worked-out gas fields, it can also be fed directly to fruit and vegetables that are being grown in greenhouses.
- Keadby is surrounded by the flat lands of Lincolnshire.
How long will it be before we see tomatoes, strawberries, peppers and cucumbers labelled as British zero-carbon products?
Offshore Hydrogen
I’ll repeat what I said in ITM Power and Ørsted: Wind Turbine Electrolyser Integration.
This is from a press release from ITM Power, which has the same title as the linked article.
This is the introductory paragraph.
ITM Power (AIM: ITM), the energy storage and clean fuel company, is pleased to share details of a short project sponsored by the Department for Business, Energy & Industrial Strategy (BEIS), in late 2019, entitled ‘Hydrogen supply competition’, ITM Power and Ørsted proposed the following: an electrolyser placed at the wind turbine e.g. in the tower or very near it, directly electrically connected to the DC link in the wind turbine, with appropriate power flow control and water supplied to it. This may represent a better design concept for bulk hydrogen production as opposed to, for instance, remotely located electrolysers at a terminal or platform, away from the wind turbine generator, due to reduced costs and energy losses.
Some points from the remainder of the press release.
- Costs can be saved as hydrogen pipes are more affordable than under-water power cables.
- The proposed design reduced the need for AC rectification.
After reading the press release, it sounds like the two companies are performing a serious re-think on how wind turbines and their links to get energy on-shore are designed.
- Will they be using redundant gas pipes to bring the hydrogen ashore?
- Will the hydrogen come ashore at Theddlethorpe and use the existing gas network to get to Keadby?
It sounds inefficient, but then the steelworks at Scunthorpe will probably want masses of hydrogen for carbon-free steel making and processing.
Boosting Power Station Efficiency
There is also a section in the Wikipedia entry for Combined Cycle Power Plant called Boosting Efficiency, where this is said.
The efficiency of CCGT and GT can be boosted by pre-cooling combustion air. This is practised in hot climates and also has the effect of increasing power output. This is achieved by evaporative cooling of water using a moist matrix placed in front of the turbine, or by using Ice storage air conditioning. The latter has the advantage of greater improvements due to the lower temperatures available. Furthermore, ice storage can be used as a means of load control or load shifting since ice can be made during periods of low power demand and, potentially in the future the anticipated high availability of other resources such as renewables during certain periods.
So is the location of the site by the Trent, important because of all that cold water?
Or will they use surplus power from the wind farm to create ice?
The Proposed North Sea Wind Power Hub
The North Sea Wind Power Hub is a proposed energy island complex on the Eastern part of the Dogger Bank.
- The Dutch, Germans and Danes are leading the project.
- Along with the Belgians, we have been asked to join.
- Some reporting on the Hub has shown, airstrips in the middle of the complex to bring the workforce to the site.
- A Dutch report, says that as much as 110 GW of wind power could be developed by 2050.
- We are also looking at installing wind farms on our section of the Dogger Bank.
Geography says, that one of the most convenient locations to bring all this electricity or hydrogen gas ashore is North Lincolnshire
A Very Large Battery
I would also put a very large battery on the site at Keadby.
One of Highview Power‘s proposed 1 GWh CRYOBatteries would be a good start. This will be four times the size of the 250 MWh CRYOBattery, which the company is currently designing and building at Carrington in Greater Manchester.
Conclusion
The three power stations at Keadby are the following sizes
- Keadby 1 – 734 MW
- Keadby 2 – 803.7 MW
- Keadby 3 – 010 MW
This adds up to a total of 2447.7 MW. And if they fit carbon capture and storage it will be zero-carbon.
Note.
- Hinckley Point C is only 3200 MW and will cost around £20 billion or £6.25 billion per GW.
- Keadby 2 power station is quoted as costing £350 million. or £0.44 billion per GW.
These figures don’t include the cost of carbon capture and storage, but they do show the relatively high cost of nuclear.
Think Again, If You Think We Have Too Many Level Crossings!
These are some pictures of the level crossing on the route between Buxtehude and Cuxhaven stations.
Some seemed to be very busy, but others were just on a concrete farm track.
I think with the exception of in the electrified Bremerhaven section, I didn’t see any bridges over the route.
The other feature visible from the line, was the large number of wind turbines.
This Is What I Call A MOAB
Jamestown is a small Australian town of a few over fourteen hundred souls, probably home to several million flies and some of the most venomous spiders and snakes known to man.
I have never visited the town, but I must have flown nearly over it, when I flew a Piper Arrow around Australia with C.
Just to the North of the town is the Hornsdale Wind Farm, which consists of 99 wind turbines with a generating capacity of 315 MW.
But this is not what brought the wind farm to my attention in an article in today’s Times under a headline of Biggest Ever Battery Plugs City’s Energy Gap.
This is said.
The battery array was built after a high-stakes bet by Elon Musk, 46, the US technology billionaire behind Tesla electric cars, that he could meet a 100-day building deadline or he would give the system away.
Wikipedia has a section on this battery.
This is said.
South Australia received 90 proposals and considered 5 projects. Tesla, Inc. is building the world’s most powerful lithium ion battery adjacent to the wind farm. It has two sections; a 70 MW running for 10 minutes, and a 30 MW with a 3 hour capacity. Samsung 21700-size cells are used.
It will be operated by Tesla and provide a total of 129 megawatt-hours (460 GJ) of storage capable of discharge at 100 megawatts (130,000 hp) into the power grid. This will help prevent load-shedding blackouts and provide stability to the grid (grid services) while other generators can be started in the event of sudden drops in wind or other network issues. It is intended to be built in 100 days counting from 29 September 2017, when a grid connection agreement was signed with Electranet, and some units were operational. The battery construction was completed and testing began on 25 November 2017. It is owned by Neoen and Tesla, with the government having the ability to call on the stored power under certain circumstances.
It certainly seems to be the Mother-Of-All-Batteries! Hence MOAB!
The Times is reporting that the battery system has cost £30 million.
This works out at about £233,000 to store each Megawatt-Hour stored.
When you consider that we have five offshore that are bigger than the Hornsdale Wind Farm, surely it is only a matter of time before we add a battery to one.
These MOABs are an intriguing concept!
Amber Rudd Puts Onshore Wind Out Of Its Misery
I don’t like onshore wind farms so I was pleased to see this announcement by Amber Rudd on the BBC, which is titled Earlier end to subsidies for new UK onshore wind farms.
Onshore wind blights the countryside and you have to use a lot of subsidy to make a development viable.
But, I mainly don’t like the concept of wind power, because it is too mechanical, as opposed to solar, where you put up a panel and its control system and you get electricity.
Solar’s other big advantage is just emerging and that is the ability to link it to an intelligent battery such as the Tesla Powerwall to provide an independent power system for a building or something remote that needs good clean energy.
In a few years time, I predict that all new houses will have solar panels on the roof and the next generation of storage battery in the garage. Coupled with increases in insulation quality, I also think, we’ll see the likes of Barratt advertising houses with no external gas and only a stand-by electricity connection, for use on the dullest days.
The big energy companies won’t like it! But surely this is the sign of a good idea?
My energy usage isn’t high, but when the solar/battery powerplant drops in price sufficiently, I’ll fit one!
Are Wind Farms A Good Idea?
A wind turbine in Devon has collapsed in high winds according to this article on the BBC.
I suspect engineers and investigators will find the cause of the collapse, but it illustrates one of the problems with turbines.
Failures like these stiffen the resolve of people, who don’t want them nearby, making the costs of the installation even more uneconomic.
If we need to develop renewable power sources, there are better systems available, than putting multiple blots on the landscape.
Is This A Serious Or Crazy Idea?
There has been a story today about large numbers of very large wind turbines being built in the Irish midlands and the power generated being exported to the UK. Ireland would get quite a few jobs.
I think it could be one of those schemes, that may be al right in theory and budget, but doesn’t perform as it should, when it is built. In the article on the BBC web site, there are these closing paragraphs.
Richard Tol, professor of economics at University of Sussex, said he felt that the whole scheme was “crazy” and would not work in the long term .
“From an Irish perspective this is not selling the family silver; this is giving it away. There is no money staying in Ireland that I can see.
“But from the British perspective it is a good deal,” he said.
It would appear it’s being very much imposed on the Irish people and the Irish are not stupid.
So I would be very surprised if the scheme is ever fully implemented. But then I don’t like blots on the landscape, whether I can see them or not!
If we are going to have large wind farms, in my view the best place for them is offshore.
A Rant From France
I received this comment last week and feel it should be posted.
Hello Anonymous,
I came across your blog whilst doing my daily research regarding wind farms.
I live in rural France and now have six x 140 metre high wind turbines…….one of which is under 600 metres from my home.
The value of my property has dropped by around 40%? Exactly how this percentage is arrived at I do not know. I can say the estate agent I asked to come and see my property was “shocked”! by the size of the turbines and the close proximity of them to my home.
He was also amazed that I was not getting any money for having them so close to my property.
He declared that I had a lovely home, beautiful garden and extremely attractive gite, he then said what a pity about the windfarm…….getting people to come to the house would be the biggest hurdle as the turbines loomed from every angle over my property,enough to put most people off before they even got here. He felt ( and I can only agree) that given a choice most people would not choose my property over a property without a wind farm so close. Now how bloody obvious is this!!!? For goodness sake…….so here I am with a blighted home, with a mortgage, with noise issues. I am just one of many in this situation.Our neighbours host the turbines on their land and receive around 25,000 Euros a year plus, the village 2.5 kilometres from where I live also receives around the same amount. I have received absolutely nothing apart from a complete change of circumstances as to how I now live my life. There are of course worse things in life then having a wind farm next door but it is the way “we” are simply overlooked and referred to as selfish! that I cannot understand.People need to “wise up” as to just how crushing it can be to have turbines so close to them.I am forever reading about people not understanding why turbines can be so unpopular……it is only the people who have to live next to them who really know why.Visiting a wind farm is not anything like living with one and yet again and again groups of people are taken on a visit for a couple of hours so they can make an “informed” decision about having a wind farm near them………please everybody wake up! bit of a rant I suppose.?
All I can do is sympathise!
My views on wind farms are detailed here.
Coalition At War Over Wind Farms
This headline is on the front of today’s Sunday Times. The row is also reported here in the Telegraph.
It is to be expected.
I must be one of the few green individuals, who is totally opposed to onshore wind farms. Offshore ones are a different matter.
I’ll give you a simple personal example, which is not about wind farms, but about visual intrusion. My previous house had one of the best views in Suffolk. But it wasn’t perfect, as a water tower on the horizon spoilt the view. Now I only joked about it and on some of the photos, I air-brushed it out. And it was after all several kilometres away on the outskirts of Haverhill. If they decided to knock it down, I’d have bought drinks all round. Now that was one water tower, how would I have felt about a line of wind turbines on the intervening ridge. It would have probably made my house unsaleable.
So I can understand why people get upset about visual intrusion.
But let’s face it too, most who live in the countryside are some of the most energy wasteful people you could want to meet. Many have large uneconomical vehicles that they drive up and down from London every weekend. And they often live in large energy-inefficient houses. So asking them to accept wind turbines is like asking a vegan to eat meat every day.
No wonder the countryside, which generally votes Tory, doesn’t want wind turbines.
In fact I find it rather surprising that anybody, anywhere in the world, wants wind turbines on a beautiful landscape. It’s just like sticking fake moles all over the Mona Lisa.
I am surprised that wind farms haven’t come under physical attack from their opponents. But I can’t find any incidents on the Internet.
Offshore wind farms though should be developed.
There is so much less visual intrusion and I believe innovative designs can make them bigger and at less cost per watt. I’m possibly back to my old favourite of the Balaena.
