25-Year-Old Danish Offshore Wind Farm Gets Approval To Operate For 25 More Years
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
After approving the production permit extension for the Samsø offshore wind farm earlier this month, the Danish Energy Agency (DEA) has now granted extended permits to two more of Denmark’s oldest offshore wind farms, Middelgrunden and Nysted.
These first two paragraphs add more details.
To support its decisions, the DEA has requested that the applicants for the production permit extensions deliver an impartial analysis of the remaining lifetime. After receiving the extensions, the owners are now obliged to carry out comprehensive annual service inspections.
The Middelgrunden offshore wind farm was built in 2000 and received its electricity production permit the same year, before full commissioning in March 2001. The DEA has now approved Middelgrunden to operate for 25 more years.
This must be a very good thing, if with a good well-planned maintenance regime, engineers can get a productive life of fifty years out of an offshore wind farm.
With nuclear power stations, engineers seem to be able to predict their life expectancy fairly well, so if we can do the same with wind farms, it must make the planning of future power capacity a lot easier.
I asked Google for an answer to how long do nuclear power stations last and got this AI Overview.
Nuclear power plants are typically designed to operate for 40 to 60 years, but some can be extended to 80 years or even longer with upgrades and maintenance. Early plants were often designed for 30 years, but many have been refurbished to extend their operational life, according to the World Nuclear Association. The actual lifespan can also depend on factors like financial viability, operating costs, and the need for decommissioning, according to the National Grid Group.
As I suspect that solar farms could remain productive for fifty or sixty years, a mix of nuclear, solar and wind should serve us well in the future. Especially, as every next generation of nuclear, solar and wind power should be better than the last.
As a very experienced mathematical modeller, I like it.
Offshore Solar Farm Ready For Tow Out To Hollandse Kust Noord Wind Project
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
What is described as the “world’s first” offshore solar farm integrated within a wind farm has completed assembly at the Port of Amsterdam and is ready for deployment at the Hollandse Kust Noord (HKN) offshore wind farm in the North Sea.
These two paragraphs give more details about the project.
Dutch company Oceans of Energy assembled the floating solar farm in three days. The system will be towed 18.5 kilometres offshore this summer to be installed at the HKN site, operated by CrossWind, a joint venture (JV) between Shell and Eneco.
According to Oceans of Energy, the project uses prefabricated floating solar units designed for offshore conditions and is seen as a step toward scaling hybrid wind-solar developments.
There are several ways to generate renewable energy.
As wind, solar, tidal and wave power are often out of phase with each other, if you are using two together in a hybrid setup, then it is probably not a bad idea to add a BESS or other form of storage to the mix.
In Oceans of Energy To Build Offshore Solar Array At Hollandse Kust Noord Offshore Wind Park, I said that the Dutch were putting batteries in the design of Hollanse Kust Noord offshore wind farm.
E.ON Invests £4 million In Allume Energy To Boost Solar Rollout For Flats
The title of this post, is the same as that of this article on Solar Power Portal.
These three paragraphs explain the deal and say a small amount about Alume’s SolShare system.
Energy supplier E.ON UK has today (17 June) announced that it has signed a strategic investment agreement with Australian firm Allume Energy to help the firm expand into the UK.
E.ON UK has invested £4 million into Allume Energy to enable Allume to expand the reach of its SolShare technology within the UK market. SolShare allows solar energy from a single rooftop solar PV installation to be fairly shared amongst multiple homes in the same building in order to allow residents of flats to access solar PV energy.
Residents are supplied their energy when they are using by a pre-determined allocation, allowing them to lower their energy bills. Many blocks of flats that do have solar panels fitted currently only use this energy to power the common areas of the building while residents still pay their full electricity bill. According to Allume, a shared rooftop solar PV system can reduce resident energy bills by between 30% and 60%.
I must say, that when I read this article, it had something of the too-good-to-be-true about it.
But.
- My solar installation on a fair-sized roof cost me about £6,000 and I am constantly surprised at how much electricity it provides.
- If you have fifty flats, they all won’t do their weekly washing at the same time each week.
- I wouldn’t be surprised to see a big battery somewhere or a small battery in each flat.
- The batteries could soak up any excess electricity or charge on cheap-rate overnight electricity.
- Do Allume’s engineers go through every flat and make suggestions about saving energy?
- Is the pattern of electricity usage in a block of flats predictable from past usage and factors like weather, the time of the year and what’s on television?
- I wouldn’t be surprised that Allume have performed extensive mathematical modelling on blocks of flats.
I think this deal could be a winner foe E.ON, Allume and their customers.
I have some ideas about the use of the system.
Would It Work On A Small Housing Estate?
A small housing estate would be a number of solar roofs feeding a number of houses, whereas with flats it will be one roof feeding a number of dwellings.
I suspect that with a well-designed sharing and pooling system, a lot of features of the flat-powering system could be used to power houses.
How Does The System Handle Electric Vehicles?
The system could use these to store electricity, so that they are always charged at the cheapest rate.
And when there is a shortage of electricity, the electricity could be borrowed by the Allume system.
Conclusion
If you have community sharing their own source of electricity, you can probably make ideas work, that wouldn’t in a single application.
My nose says Allume’s idea has legs.
Sport England Funds Leisure Centres Rooftop PV Installations
The tiitle of this post, is the same as that of this article on Solar Power Portal.
These two introductory paragraphs give a few more details and describe two installations.
Two local authority-owned leisure centres have received rooftop solar panel installations thanks to funding from Sport England.
Sport England’s Swimming Pool Support Scheme is a national scheme that has thus far distributed over £80 million to improve the energy efficiency of public swimming pools across the UK. Most recently, Workington Leisure Centre in Cumberland has installed a 160kW solar array, while Witham Leisure Centre near Braintree, Essex, has completed a 407kW solar panel installation.
After reading the whole article, it looks to me that leisure centres with their large areas and generous car parking, are a good application for solar panels, that can be of benefit to users, operators, solar panel installers and their financiers.
My experience of finance was mainly in providing funding for vehicles, but once a finance company finds a profitable niche, they are good at exploiting it.
Out of town retail premises and sports stadiums could be other profitable applications.
UK Solar Applications Spike Ahead Of CP30 But Planning Process Remains Slow
The title of this post, is the same as that of this article on Solar Power Portal.
This is the sub-heading.
Solar Media Market Research analyst Josh Cornes tracks the time solar PV developments spend in the planning system, as delays and refusals slow the rate of buildout.
These three introductory paragraphs add more detail.
Solar PV buildout in the UK continues to pick up, with year-on-year growth forecast for 2025, the seventh year of growth in a row.
With government-led initiatives like Clean Power 2030 (CP30) encouraging buildout and the Contracts for Difference (CfD) mechanism incentivising development, this growth is unlikely to slow down.
However, there are several factors at play stunting this growth, hurting the UK’s chances of hitting the CP30 target of 45-47GW solar generation capacity by 2030.
The article also talks about the problems of grid connections and says that some solar farms will take thirty-three years to get a connection.
In Technology Behind Siemens Mobility’s British Battery Trains Hits The Tracks, I said this.
Cameron Bridge station is lucky in that there is already a 132,000 KVAC electricity connection to the distillery next door.
But at other places, where there is no connection, you could wait as long as seven years to be connected to the grid.
So could the clever engineers at Siemens, devise some sort of electrical gubbins, that connects a solar farm directly to Siemens innovative Rail Charging Converter?
Instead of needing two connections to the grid, the setup won’t need any.
Surely, other types of users could be driven directly, or through an appropriately sized battery?
Government Approval For Large Solar Farm
The title of this post, is the same as that of this article on the BBC.
This is the sub-heading.
A large solar farm in East Yorkshire has been given the go ahead by the government.
These two introductory paragraphs add more detail.
The 3,155 acre (1,277 hectares) site will be built on land around Gribthorpe, Spaldington and Wressle and Howden.
Its developers said it would produce 400 megawatts of electricity – enough to power 100,000 homes.
Note.
- This solar farm is five square miles or a 2.2 mile square.
- Due to the size of the scheme the planning application was handled by the Planning Inspectorate as it was classed as national infrastructure.
- Ed Miliband may have been involved in the final decision.
- The solar farm would connect to the National Grid at the Drax substation in North Yorkshire.
But the solar farm is not without opposition, as these last three paragraphs indicate.
George McManus, spokesman for East Riding Against Solar Expansion (ERASE), said the approval “brings us a step closer to enormous swathes of agricultural land being blanketed in a million, Chinese manufactured, solar panels.”
He added: “Other projects in the pipeline will see another 20,000 acres disappear under glass.
“The East Riding is being industrialised and people need to wake up to that.”
Nothing is said about where Reform UK’s Mayor for Hull and East Yorkshire sits.
DESNZ Launches Call For Evidence For Solar Carports In The UK
The title of this post is the same as this article on Solar Power Portal.
These three paragraphs introduce the article.
The UK Department for Energy Security and Net Zero (DESNZ) has launched a call for evidence to help increase the number of solar-powered carports in England, Wales, and Northern Ireland.
The likely result of this will be a mandate that car parks have a solar PV installation, as has been the case in France for some time.
Mandating solar on car parks has multiple benefits, which DESNZ is keen to emphasise. It says that a mandate would be a “better deal for motorists and businesses”
I may not be a fan of electric cars, but I’m certainly no fan of spreading solar panels over large areas of quality farmland.
There are some interesting statements.
Take this one.
DESNZ cites estimates that supermarkets, retail parks and offices could save up to £28,000 annually by installing solar carports (this figure calculated for an 80-space car park—the size that France mandates must be covered by solar PV) if all of the electricity generated by the solar array was used onsite.
£28,000 a year is not to be sneezed at!
And this one.
Earlier this year, Norwich-based RenEnergy, a solar carport provider, revealed that installing solar carports in more than half a million suitable parking spaces owned by UK businesses could generate 1.57GW of solar energy.
They do suggest that this figure only scratches the surface.
And then there’s this story from Bentley.
In 2019, Bentley Motors installed a solar car park at its headquarters in Crewe. The site’s 10,000 solar PV modules have a capacity of 2.7MW and cover an area of 16,426m². Along with other installed solar arrays and 6.6MW of battery energy storage, the car park enables all of Bentley’s manufacturing operations to be powered by solar or certified green energy.
How many other businesses could do that?
This Google Map shows the Bentley Motors site at Crewe.
Note.
- It appears to be a large site.
- Bentley employs over 4,000 employees at Crewe.
- In 2023, Bentley delivered 13, 560 cars.
- The solar car ports appear to be at the Western end of the site.
- There would appear to be a lot of scope to add more solar car ports at the Eastern end of the site.
Running along the Southern edge of the site is the North Wales Coast Line, which runs between Crewe and Chester and then on to North Wales.
I would have thought, that a case could be made out to have a station at the Bentley site for employees and visitors.
There also doesn’t seem to be the infrastructure, so that cars to some destinations can be delivered by train, like these from Toyota, which I photographed at Denmark Hill station, which were on the way to Europe, through the Channel Tunnel.
Perhaps sending luxury cars to their future owners by train is the wrong image.
Shawton Energy Joins Up With The Co-Op For Rooftop Solar
The title of this post, is the same as that of this article on Solar Power Portal.
These two paragraphs describe the agreement.
Renewable technology developer Shawton Energy has signed an agreement with the Co-Op group to help support the retail giant’s rollout of rooftop solar PV.
Working with Sol PV as a delivery partner, Shawton Energy will design, develop, fund, and manage rooftop solar PV systems at key Co-op locations using a power purchase agreement (PPA) model. This allows Co-op to make significant energy and cost savings without having to put forward any upfront investment. Co-op will now purchase the power from Shawton Energy at a flat, discounted rate. While this rollout currently only covers some of the Co-Op’s over 2,500 retail locations, there remains potential for expanding this partnership in the future.
This looks to me to be a deal, where all parties benefit.
- Co-op have thousands of locations, that could have solar roofs, which would be good green publicity.
- I suspect that the Co-op own a lot of their properties, so the collateral is there, if the deal goes wrong.
- I suspect many buildings are very similar, so design and installation costs could be reduced.
- Co-op get reduced-cost electricity.
- Shawton Energy can add other technologies like batteries and rooftop turbines to the deal.
From my experience of both sides of the leasing of multiple systems, I believe, that this would be the sort of deal, that reputable banks and finance houses would be very happy to fund.
It looks like the sort of deal that can be replicated.
Especially, as Shawton Energy have already done a deal with the Bannatyne Group, according to these two paragraphs from the article.
This is not the first significant deal with a well-known British chain that Shawton Energy has agreed this year. The company announced in March of this year that it had made an agreement with health and wellness club operator the Bannatyne Group, which has installed solar panels on the rooftops of a number of its health clubs, hotels and spas under a similar PPA agreement to that Shawton Energy has made with the Co-Op.
According to the Bannatyne Group, the installations, which consist of 967 panels and 11 inverters across eight sites around the UK, have already provided significant energy savings to the group. Since their completion, each of the eight sites has reportedly secured energy savings of up to 25%.
Savings of 25 % are worth having.
E.ON, Superdielectrics Develop Polymer-Based Battery Tech For Residential Storage Applications
The title of this post, is the same as that of this article on the Solar Power Portal.
These two introductory paragraphs outline the deal.
Energy supplier E.ON and energy storage technology firm Superdielectrics have joined forces to promote and develop a new battery technology for stationary storage applications.
The new BESS technology takes a unique approach by using a polymer-based technology, with the main component being a membrane similar to contact lens materials. According to the two companies, these polymer batteries are both more affordable and more environmentally friendly than their lithium-ion counterparts.
I believe that this battery could be a game-changer. Especially, for those like me, who have solar panels on their roofs.
Check out the Superdielectrics web site for more details.
I First Spotted Superdielectrics In 2019
I wrote about them in Is Cambridge Going To Save The World From Global Warming? in 2019.
This was my conclusion in that post.
I have been observing technology since the 1960s.
This is either one of those scientific curiosities , like cold fusion, that appear from time-to-time and then disappear into the scientific archives or become a game-changer.
I suspect we’ll know in a couple of years.
But even if it is isn’t the solution to affordable and massive energy storage,, that will save the world, I believe that one of the teams of men and women in white coats, somewhere in the world will crack the problem.
It looks like they’ve taken longer than I thought they would.
Note though, that in the linked post, they have a link-up with Rolls-Royce.
Conclusion
This is one of the great energy breakthroughs of my life-time.
