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?

Could A Highview Power CRYOBattery Provide Backup Power For A Large Data Centre?

I asked Google AI how much power does a data centre need and got this answer.

The power requirements for an average data center vary greatly depending on its size and purpose, ranging from 1-5 MW for small facilities to 20-100 MW or more for large hyperscale centers. Small data centers, typically with 500-2,000 servers, might need 1-5 MW of power, while large or hyperscale data centers, housing tens of thousands of servers, can consume 20-100 MW or even more.

As Highview Power are currently building four 200 MW/2.5 GWh CRYOBatteries for the UK, I am fairly sure the answer is in the affirmative.

Ambitious £3bn Pumped Hydro Project At Loch Ness Moves Forward

The title of this post is the same as that of this article on Sustainable Times.

These are the two introductory paragraphs.

A £3 billion pumped storage hydro (PSH) project near Scotland’s iconic Loch Ness is one step closer to becoming a reality. Glen Earrach Energy (GEE) confirmed on April 25th that it has officially submitted the planning application for its ambitious 2gw scheme.

If greenlit, this project would represent nearly three-quarters of the total PSH capacity planned for Loch Ness, contributing 34 GWh of the region’s 46 GWh storage goal. But it’s not just the storage that stands out. This development would also account for two-thirds of the generating capacity, all while using just half of the water previously considered. To put it into perspective, the project’s capacity would be on par with the combined output of around 800 onshore wind turbines scattered throughout the Highland Council area.

Note.

  1. The generating and pumping capacity for this ambitious scheme is given as 2 GW. Only three in China and one in the United States are larger.
  2. The storage capacity of 34 GWh will make it the largest in the UK, possibly the second largest in Europe to Ulla-Førre in Norway and one of the ten largest in the world.
  3. A projected 10% reduction in the UK grid’s carbon footprint is claimed.
  4. The cost of three billion is high, but compare that with the tens of billions quoted for the 3.26 GW Hinckley Point C.

The Glen Earrach scheme is not short on superlatives and the article in Sustainable Times is worth a thorough read.

Fifth Hydro Project Proposed At Loch Ness, is based on a BBC article of the same name.

These were my thoughts in the related post.

The Existing Hydro Schemes On Loch Ness

According to the BBC article, there are two existing hydro schemes on Loch Ness.

  • Foyers is described on this web site and is a reasonably modern 305 MW/6.3 GWh pumped storage hydroelectric power station, that was built by SSE Renewables in the last fifty years.
  • Glendoe is described on this web site and is a modern 106.5 MW conventional hydroelectric power station, that was built by SSE Renewables in the last twenty years.

Foyers and Glendoe may not be the biggest hydroelectric power stations, but they’re up there in size with most solar and onshore wind farms. Perhaps we should look for sites to develop 100 MW hydroelectric power stations?

The Proposed Hydro Schemes On Loch Ness

According to the BBC article, there are four proposed hydro schemes on Loch Ness.

  • Coire Glas is described on this web site and will be a 1.5GW/30 GWh pumped storage hydroelectric power station, that is being developed by SSE Renewables.
  • Fearna is described on this web site and will be a 1.8GW/37 GWh pumped storage hydroelectric power station, that is being developed by Gilkes Energy.
  • Loch Kemp is described on this web site and will be a 600MW/9 GWh pumped storage hydroelectric power station, that is being developed by Statera.
  • Loch Na Cathrach is described on this web site and will be a 450MW/2.8 GWh pumped storage hydroelectric power station, that is being developed by Statktaft.

In addition there is, there is the recently announced Glen Earrach.

  • Glen Earrach is described on this web site and will be a 2GW/34 GWh pumped storage hydroelectric power station, that is being developed by Glen Earrach Energy.

Note.

  1. The total power of the seven pumped storage hydroelectric power stations is 4.76 GW.
  2. The total storage capacity is 89.1 GWh.
  3. The storage capacity is enough to run all turbines flat out for nearly nineteen hours.

I estimate that if 2 GW/34 GWh of pumped storage will cost £3 billion, then 4.76 GW/89.1 GWh of pumped storage will cost around £7-8 billion.

Avacon And Rolls-Royce Are Testing The Contribution Of Battery Storage And PV Systems To Grid Stability

The title of this post, is the same as that of this press release from Rolls-Royce.

These two bullet points act as sub-headings.

  • Field tests are investigating the intelligent integration of renewable energies with home storage systems and larger mtu battery storage systems
  • Objective: to contribute to the efficient energy supply of energy communities and grid support

This introductory paragraph adds more detail.

German energy supplier Avacon and Rolls-Royce together are driving forward the integration of battery storage into the power grid as part of a research project. Based on a field test, the aim is to show how energy communities, PV systems and mtu battery storage can be intelligently linked to contribute to an efficient energy supply and to stabilize the energy system. Avacon and Rolls-Royce are already collaborating on a second research project. The aim is to use battery storage to moderate generation peaks from PV systems and bring them into line with electricity consumption.

This all takes me back to the early 1970s, when my software was used by the Water Resources Board to plan future water supply in the South of England.

Given, that we don’t seem to suffer supply problems with water in the South, I feel that Dr. Dave Dimeloe and his team did a good job.

Some of the techniques, that I used fifty years ago, would allow an accurate model to be made of what Rolls-Royce call an energy community.

But my experience with water and later with the flow of money in peer-to-peer lending, lead to my thinking that energy communities will be stable.

But that is for Rolls-Royce to prove or disprove.

Earba 1.8GW Pumped Storage Hydro Project Secures Approval

The title of this post, is the same as that of this article on the Solar Power Portal.

These three paragraphs introduce the article.

Gilkes Energy has been awarded planning consent for its Earba Pumped Storage Hydro (PSH) scheme.

The Earba PSH scheme is set to be the largest project of its kind in the UK, with an installed capacity of 1.8GW and a storage capacity of 40GWh, meaning that it can provide 22 hours of storage at full power. The planning application for the project was submitted to the Scottish government in early March 2024.

The project will be located at Loch Earba in the Scottish central Highlands. Gilkes Energy states that this location was chosen because the area has an ideal combination of geology and topography, which the firm states will make it one of the most economically viable PSH projects under development in the UK.

In Gilkes Reveals 900MW Scottish Pumped Storage Plan, I said that Loch Earba was a 900 MW/33 MWh PSH scheme, but now it appears a it is 1.8 GW/40 GWh scheme, which will probably put it in the largest twenty PSH schemes in the world.

It will be one of four PSH schemes under development in Scotland.

  • Coire Glas – 1.3 GW/30 GWh
  • Loch Earba – 1.8 GW/40 GWh
  • Loch na Cathrach (formerly known as Red John) – 450 MW/2.8 GWh
  • Loch Sloy – 160 MW/16 GWh

In addition.

  • Cruachan is being extended to 1 GW/7 GWh.
  • Highview Power are planning to build two 200 MW/2.5 GWh of their liquid air batteries in Scotland.

Everything totals up to 5.1 GW/100.8 GWh, which compares with a UK electricity production as I write this article of just under 29.5 GW.

I wouldn’t be surprised to see some high-energy industries moving to Scotland because of all this renewable and hopefully reliable power.

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.

Chinese firm ‘Will Not Bid’ To Run Essex Nuclear Plant

The title of this post, is the same as that of this article on The Times.

This is the sub-heading.

Sources no longer expect planning applications to be submitted by China General Nuclear Power Group for Bradwell B

These three paragraphs give brief details of the current situation.

Plans for China’s state-run nuclear company to develop and operate a proposed nuclear site in Essex will no longer go ahead, The Times can reveal amid renewed focus on Chinese involvement in Britain’s critical infrastructure.

Bradwell B, the proposed nuclear power station, was earmarked for investment by China General Nuclear Power Group (CGN) in 2015. CGN is the majority investor in the proposed development alongside French energy company EDF.

But government and industry sources told The Times and Times Radio they no longer expected planning applications to be submitted by CGN for the site, and EDF will look to take back the lease from the Chinese firm at the earliest opportunity.

So what will happen to the Bradwell Site?

This Google Map shows the Blackwater Estuary to the North of Southend.

Note.

  1. The Blackwater Estuary is at the top of the map.
  2. Bradwell Marina and Bradwell-on-Sea can be seen on the map to the South of the Blackwater Estuary.
  3. Southminster has a rail connection, which was used to handle the nuclear fuel and now has a passenger service to Wickford on the Southend Victoria to London Liverpool Street Line.

This second Google Map shows Bradwell-on-Sea and the North of the peninsular in greater detail.

Note.

  1. The remains of the three runways of the Second World War RAF Bradwell Bay can be picked out.
  2. The remains of Bradwell A nuclear power station are towards  the coast to the North-West of the former runways.
  3. It is large site.

I wonder, if the site could be used for backup to all the offshore wind farms in the area.

This is a list of all the wind farms, that are planned in the sea to the North and East of the Bradwell site.

  • The East Anglia Array is partly operational, but could grow to as much as 7.2 GW.
  • Greater Gabbard is 504 MW
  • Gunfleet Sands is 172 MW
  • London Array is 630 MW
  • North Falls is 504 MW

Note.

  1. That is a total of roughly 9 GW.
  2. There’s also plenty of space in the sea for more turbines.

All these wind turbines will need backup for when the wind goes on strike.

These are possibilities for backup.

Another Hinckley Point C Or Sizewell C

You can see why the government wants to build a big nuke on the Bradwell site.

The 3.26 GW of  a power station, which would be the size of Hinckley Point C would provide more than adequate backup.

But the builders of these power stations haven’t exactly covered themselves in glory!

  • Construction of Hinckley Point C started in the late 2010s and first power is expected in 2031.
  • Hinckley Point C power station has all the stink of bad project management.
  • The Nimbbies would also be out in force at Bradwell.

There are also all the financial problems and those with the Chinese, indicated in The Times article.

A Fleet Of Small Modular Reactors

Hinckley Point C will hopefully be a 3260 MW nuclear power station and Rolls-Royce are saying that their small modular reactors will have a capacity of 470 MW.

Simple mathematics indicate that seven Rolls-Royce SMRs could do the same job as Hinckley Point C.

The advantages of providing this capacity with a fleet of SMRs are as follows.

  • Each reactor can be built separately.
  • They don’t all have to be of the same type.
  • The total 3260 MW capacity could also be built at a pace, that matched the need of the wind farms.
  • Building could even start with one of each of the chosen two initial types, the Government has said it will order.
  • I also believe that there could be advantages in the sharing of resources.
  • The rail link to Southminster would enable the bringing in of the smaller components needed for SMRs by rail.

Hopefully, the power of a big nuke could be added to the grid in a shorter time.

A Number of Long Duration Energy Stores

Highview Power is building 4 x 200 MW/2.5 GWh liquid air batteries for Orsted in the UK ; 2 in Scotland and 2 in England. They are backed by the likes of Centrica, Goldman Sachs, Rio Tinto, the Lego family trust and others.

Each GWh of liquid air needs a tank about the largest size of those used to store LNG. I suspect like LNG tanks they could be partly underground to reduce the bulk.

A Hybrid System

Bradwell is a large site and could easily accommodate a pair of Highview Power batteries, two SMRs, and all the other electrical gubbins, which would total to around 1.5 GW/5 GWh. This should be sufficient backup, but there would be space to add more batteries or SMRs as needed.

Another Headache For Fossil Fuels: Liquid Air Energy Storage

The title of this post, is the same as that of this article on Clean Technica.

This article is an honest American look at Highview Power’s liquid air batteries and a must-read.

This is the first paragraph.

Whatever happened to liquid air energy storage? The UK startup Highview Power was going to bring its new liquid air system to the US back in 2019, providing the kind of scaled-up and long duration energy storage needed to support more wind and solar power on the grid. Highview switched gears and headed back home where the grass is greener. Our loss is the UK’s gain…

They first wrote about Highview Power in 2011, which shows how long some of these projects take to come to fruition.

The article also has this view on the state of offshore wind in the United States today.

Perhaps it’s just as well that Highview dropped its US plans when it did. Offshore wind stakeholders in the US were just beginning to find their footing along the Atlantic coast when President Trump took office on January 20 and promptly sent the offshore industry into a death spiral.

If I lived in the US today, I’d thinking about leaving given Trump’s barmy energy policies.

This paragraph from Highview Power’s web site, discloses their backers.

The £300 million funding round was led by the UK Infrastructure Bank (UKIB) and the British multinational energy and services company Centrica, alongside a syndicate of investors including Rio Tinto, Goldman Sachs, KIRKBI and Mosaic Capital.

So at least some American companies believe in Highview Power. KIRKBI is the investment vehicle of the family, that invented Lego.

SSE Files Plans For 100 MW Pumped Hydro Scheme

The title of this post is the same as that of this article on reNews.biz.

This is the sub-heading.

Proposal aims to convert iconic Sloy Power Station into storage facility by end of 2030

These three paragraphs outline the proposals.

SSE has submitted plans to the Scottish Government for the 100MW Sloy pumped storage hydro scheme.

The plans would see the existing Sloy Power Station – a conventional hydro power station – on the banks of Loch Lomond converted into a pumped storage hydro scheme with a pumping capacity of up to 100MW.

If given the green light, the converted Sloy scheme would be capable of delivering up to 16GWh of long-duration electricity storage capacity.

SSE intend to make an investment decision by late 2027 and this is said about increasing capacity.

As part of the planning application, SSE Renewables is also proposing to upgrade the existing 32.5MW G4 turbine to match its sister units, which would increase the station’s generating output by 7.5MW to 160MW.

This appears to be a world-class example of canny Scottish engineering.

The project would turn the current 152.5 MW hydroelectric power station into a 160 MW/16 GWh pumped storage hydroelectric power station.

Not a bad transformation, that was opened three years after I was born.

Backing Up The Wind With The Keadby Power Stations

I went to Cleethorpes from Doncaster by train yesterday. You pass the Keadby site, where there are two large gas–fired power stations of 734 MW and 710 MW. A third one ; Keadby 3 of 910 MW complete with carbon capture and storage should join them by 2027.

So that will be nearly 2.5 GW of reliable electricity.

I find it interesting that one of our first gas-fired power stations with carbon capture will be in Lincolnshire, which is famous for growing plants of all shapes, types and sizes. So will we be seeing lots of greenhouses on the flat lands I saw yesterday, growing plants in an atmosphere they like, so that we can generate our carbon dioxide and eat it.

 

The next power station at Keadby is called the Keadby Next Generation power station, which is intended to be complete by 2030. It is a bit of a puzzle in that it will run on up to 1800 MW of hydrogen and only produce up to 910 MW of electricity.

Note.

  1. The hydrogen will come from SSE’s hydrogen store at Aldbrough and Centrica’s store at Rough.
  2. Surely, the amount of hydrogen and electricity should balance.

When I worked in ICI’s hydrogen plant in the 1960s, ICI had no use for the hydrogen, so they sent it to their power station, blended it with coal gas and used it to make steam for other processes.

Could Keadby Next Generation power station be providing zero-carbon steam for the chemical and other processes on Humberside?

Adding the 910 MW of electricity to Keadby’s gas-fired total of 2.5 GW gives 3.4 GW of electricity from Keadby to back up the wind farms.

3.4 GW at Keadby is what I call backup!

It also should be noted, that one of the reasons for building the Mersey Tidal Barrage is to provide backup for all the wind farms in Liverpool Bay.

Conclusion

I believe that SSE could be supplying zero-carbon steam in addition to electricity from the Keadby Hydrogen power station.
