£20 Electronic Ear-Clips Train The Body To Decrease Blood Pressure
The title of this post, is the same as that of this article in The Times.
These two paragraphs outline how the device is used.
A £20 device that delivers “tingling” electric pulses to the ears and can be worn at home could be almost twice as effective as drugs at reducing blood pressure, a neuroscientist has said.
Early trials suggest that wearing the small electrodes clipped to the ears for half an hour per day over two weeks while relaxing, watching TV or eating can reduce blood pressure by up to 15mm of mercury (mm Hg), compared with 8mm Hg to 10mm Hg for drugs such as Ace inhibitors or beta-blockers.
It appears the device has been developed at University College London.
Would I Use Electronic Ear-Clips To Control My Blood Pressure?
Soon after my wife died in 2007, my cholesterol levels rose.
The Ipswich Town Physiotherapist, who was a drinking partner before matches at Portman Road, recommended that I see his dietician.
She identified the following.
- My diet had changed since my my wife’s death, as I was choosing the food and doing the cooking.
- She suspected, that I wasn’t eating enough soluble fibre.
- I was eating enough fruit and vegetables.
Her solution was two-fold.
- Swap butter and other spreads for Benecol.
- Make sure, I eat, at least one small tin of baked beans every week.
Obviously, as I had been found to be coeliac in 1997, I should stay gluten-free.
I’ve seen other dieticians since and none have criticised, what she said.
No doctor has also ever said, that there is something wrong with my cholesterol.
After my stroke in 2010, I was put on Warfarin to thin my blood.
The only addition to my cocktail of drugs, was that after an unexplained collapse, I was put on blood pressure drugs.
So to return to the question I asked at the top of this section.
I may take six or seven drugs and vitamin tablets every day, but swapping one or two for half-an-hour with an electronic device wouldn’t be too much trouble.
That is, if I could tolerate the device, as I’m not keen on headphones.
But it could be an interesting alternative to taking pharmaceutical drugs.
Where’s The Plan, Rishi?
In RWE Goes For An Additional 10 GW Of Offshore Wind In UK Waters In 2030, I detailed how RWE intended to add an extra 10 GW of offshore wind to the seas around the UK.
As our current offshore wind capacity is around 15 GW, another 10 GW would surely be very welcome.
My post also outlined H2ercules, which is Germany’s massive project to create a hydrogen network to bring hydrogen to Southern Germany.
I also gave details of the hydrogen hub at Wilhelmshaven, which is being built by Uniper to feed H2ercules with green hydrogen from around the world.
I believe that some of this hydrogen for H2ercules will take a short trip across the North Sea from UK waters, after being created by offshore electrolysers.
Rishi Sunak’s Manifesto Speech – June 11
I also reported on Rishi Sunak’s Manifesto Speech, which he made on June 11th. This is an extract
This document on the Policy Mogul web site is entitled Rishi Sunak – Conservative Party Manifesto Speech – Jun 11.
These are three paragraphs from the speech.
We don’t just need military and border security. As Putin’s invasion of Ukraine has shown, we need energy security too. It is only by having reliable, home-grown sources of energy that we can deny dictators the ability to send our bills soaring. So, in our approach to energy policy we will put security and your family finances ahead of unaffordable eco zealotry.
Unlike Labour we don’t believe that we will achieve that energy security via a state-controlled energy company that doesn’t in fact produce any energy. That will only increase costs, and as Penny said on Friday there’s only one thing that GB in Starmer and Miliband’s GB Energy stands for, and that’s giant bills.
Our clear plan is to achieve energy security through new gas-powered stations, trebling our offshore wind capacity and by having new fleets of small modular reactors. These will make the UK a net exporter of electricity, giving us greater energy independence and security from the aggressive actions of dictators . Now let me just reiterate that, with our plan, we will produce enough electricity to both meet our domestic needs and export to our neighbours. Look at that. A clear, Conservative plan not only generating security, but also prosperity for our country.
It is now nine days since Rishi made that speech and I can’t remember any reports about an energy security policy, which he outlined in the last paragraph of my extract from his speech.
He particularly mentioned.
- New gas-powered stations
- Trebling our offshore wind capacity
- Having new fleets of small modular reactors.
He also said we would have sufficient electricity to export to our neighbours. As I said earlier some of this energy will be in the form of hydrogen, which has been created by offshore electrolysers.
If we are exporting electricity and hydrogen to Europe, this is likely to have three effects.
- An improvement in Europe’s energy security.
- H2ercules will improve and decarbonise German industry, using UK hydrogen.
- The finances of UK plc will improve.
It looks like there will be winners all round.
Rishi also said this, in his speech.
As Putin’s invasion of Ukraine has shown, we need energy security too.
The gas-powered stations, offshore wind farms and the fleets of small modular reactors, will be part of the equation.
But I believe, we need three other components to complete our energy security.
- The upgrading of the National Grid.
- The building of four x 2 GW interconnectors between Scotland and Eastern England.
- Large amounts of energy storage.
Note.
- The Great Grid Upgrade and the four x 2 GW interconnectors are being planned.
- In Huge Boost To UK Supply Chain As National Grid Launches The Great Grid Partnership With Seven New Industry Partners, All United In The Drive To Deliver The Great Grid Upgrade, I describe how National Grid has setup the Great Grid Partnership to deliver the Great Grid Upgrade.
- In UK Infrastructure Bank, Centrica & Partners Invest £300M in Highview Power Clean Energy Storage Programme To Boost UK’s Energy Security, I describe how the big boys do a deal with Highview Power to create affordable batteries for the UK and the world.
- In Grid Powers Up With One Of Europe’s Biggest Battery Storage Sites, I describe how the very large Swardeston BESS is to be built near Norwich.
- In Mercia Power Response & RheEnergise Working Together To Build Long Duration Energy Storage Projects In The UK, I describe another UK-developed long duration energy storage system, which is now being planned.
- In National Grid Shares Proposals For Green Electricity Projects In Lincolnshire And West Norfolk, Needed To Boost Home-Grown Energy Supplies And Progress Towards Net Zero, I describe National Grid’s projects in the East of England.
- In UK ESO Unveils GBP 58 Billion Grid Investment Plan To Reach 86 GW of Offshore Wind By 2035, I show how we’re not that far away from 86 GW by 2035.
- In 400k For National Grid Innovation Projects As Part Of Ofgem Fund To Help Shape Britain’s Net Zero Transition, I describe how National Grid is using innovation to help target net-zero by 2035.
- In Iberdrola Preparing Two East Anglia Offshore Wind Projects For UK’s Sixth CfD Round, I describe how Iberdrola is getting 1.7 GW ready for commissioning in 2026.
- In National Grid To Accelerate Up To 20GW Of Grid Connections Across Its Transmission And Distribution Networks, I describe how National Grid are accelerating the development of the electricity networks. 10 GW of battery storage is a collateral benefit.
These ten projects, most of which are financed and/or underway, would appear to be good foundations, on which to build the Great Grid Upgrade.
It looks to me, that National Grid, RWE, Centrica, Iberdrola and others, by just doing what comes naturally have offered the next government a road to a future.
It will be interesting, what gets said before the election.
How To Avoid Middle-Aged Spread: Go To Private School
The title of this post, is the same as that of this article in The Times.
This is the sub-heading.
In their mid-forties, those who were educated privately are more likely to be a healthy weight and have lower blood pressure, the research found
These two paragraphs give some more details.
People who go to private school or a Russell Group university are healthier and slimmer in middle age, research has shown.
In their mid-forties, those who were educated privately are more likely to be a healthy weight, have lower blood pressure and perform better on a cognitive task than those who went to state schools.
Note.
- I went to a good grammar school and a Russell Group University.
- So did my late wife!
- Both us were slim and fairly fit until our late fifties.
The research was from University College London.
Norway’s Sovereign Wealth Fund Acquires Stake In 573 MW Race Bank Offshore Wind Farm
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
A consortium made up of investment funds belonging to Australia-headquartered Macquarie Asset Management and Spring Infrastructure Capital has reached an agreement to divest a 37.5 per cent stake in the 573 MW Race Bank offshore wind farm in the UK to Norges Bank Investment Management.
These four paragraphs give more details of the deal.
The stake was sold to the Norwegian sovereign wealth fund for approximately GBP 330 million (about EUR 390.6 million).
According to Norges Bank Investment Management, the fund acquired Macquarie European Infrastructure Fund 5’s 25 per cent stake and Spring Infrastructure 1 Investment Limited Partnership’s 12.5 per cent interest in the Race Bank offshore wind farm.
A Macquarie Capital and Macquarie European Infrastructure Fund 5 consortium acquired a 50 per cent stake in Race Bank during the construction phase in 2016. Macquarie Capital divested its 25 per cent stake in the wind farm in 2017.
With the deal, Arjun Infrastructure Partners will remain co-investor for 12.5 per cent of the wind farm and Ørsted will remain a 50 per cent owner and operator of Race Bank.
These are my thoughts.
The Location of Race Bank Wind Farm
This map from the Outer Dowsing Web Site, shows Race Bank and all the other wind farms off the South Yorkshire, Lincolnshire and Norfolk coasts.
From North to South, wind farm sizes and owners are as follows.
- Hornsea 1 – 1218 MW – Ørsted, Global Infrastructure Partners
- Hornsea 2 – 1386 MW – Ørsted,Global Infrastructure Partners
- Hornsea 3 – 2852 MW – Ørsted
- Hornsea 4 – 2600 MW – Ørsted
- Westernmost Rough – 210 MW – Ørsted and Partners
- Humber Gateway – 219 MW – E.ON
- Triton Knoll – 857 MW – RWE
- Outer Dowsing – 1500 MW – Corio Generation, TotalEnergies
- Race Bank – 573 MW – Ørsted,
- Dudgeon – 402 MW – Equinor, Statkraft
- Lincs – 270 MW – Centrica, Siemens, Ørsted
- Lynn and Inner Dowsing – 194 MW – Centrica, TCW
- Sheringham Shoal – 317 MW – Equinor, Statkraft
- Norfolk Vanguard West – 1380 MW – RWE
Note.
- There is certainly a large amount of wind power on the map.
- Hornsea 1, 2 and 3 supply Humberside.
- Hornsea 4 will supply Norwich and North Norfolk.
- Norfolk Vanguard West would probably act with the other two wind farms in RWE’ Norfolk cluster.
- Ignoring Hornsea and Norfolk Vanguard West gives a total around 4.5 GW.
- There are also two 2 GW interconnectors to Scotland (Eastern Green Link 3 and Eastern Green Link 4) and the 1.4 GW Viking Link to Denmark.
I wouldn’t be surprised to see a large offshore electrolyser being built in the East Lincolnshire/West Norfolk area.
The primary purpose would be to mop up any spare wind electricity to avoid curtailing the wind turbines.
The hydrogen would have these uses.
- Provide hydrogen for small, backup and peaker power stations.
- Provide hydrogen for local industry, transport and agriculture,
- Provide hydrogen for off-gas-grid heating.
- Provide methanol for coastal shipping.
Any spare hydrogen would be exported by coastal tanker to Germany to feed H2ercules.
Do We Need Wind-Driven Hydrogen Electrolysers About Every Fifty Miles Or so Along The Coast?
I can certainly see a string along the East Coast between Humberside and Kent.
- Humberside – Being planned by SSE
- East Lincolnshire/West Norfolk – See above
- North-East Norfolk – See RWE Goes For An Additional 10 GW Of Offshore Wind In UK Waters In 2030.
- Dogger Bank – See RWE Goes For An Additional 10 GW Of Offshore Wind In UK Waters In 2030.
- Sizewell – See Sizewell C And Hydrogen.
- Herne Bay – Under construction
I can see others at possibly Freeport East and London Gateway.
Hybrid And Over 1.100 kW Strong: Rolls-Royce Presents New mtu Propulsion Concepts For Military Vehicles Of The Future
The title of this post, is the same as that of this press release from Rolls-Royce.
These two paragraphs detail some of the philosophy and features behind the hybrid power units.
Electrification and hybridisation will give tactical vehicles new capabilities in the field. To this end, Rolls-Royce’s new mtu hybrid drive combines the advantages of a high-performance diesel engine with those of a battery-electric drive. The highly integrated propulsion system requires comparatively little installation space in the vehicle in order to maximise the volume available for equipment and crew. The core of the solution is a highly mobile and extremely compact drive solution, taking into account increasing cost pressure, tight budgets and the need for significantly larger vehicle fleets.
For quiet operation, for example in a concealed position, the high-performance batteries previously charged in diesel mode, supply the vehicle’s electrical and electronic systems. This is done without the noise and thermal footprint of the diesel engine – and over a longer period of time. This makes the vehicle more difficult to locate for enemy reconnaissance. The so-called “anti-idling” mode not only ensures better camouflage of the vehicle, but also significantly reduces fuel consumption when the vehicle is on standby. The range of the vehicles and the downstream logistics chain for refuelling the vehicles are optimised.
Hopefully, power concepts like these will lead to highly capable fighting vehicles, that will defeat the threats we face from the East.
But surely, as hybrid power develops and embraces the use of clean fuels like green hydrogen and green methanol, power units like these will be found in other applications, both on land and on the sea.
And how about a hydrogen-hybrid rail locomotive to haul trains in noise-sensitive areas!
Vestas’s 15 MW Wind Turbine Up At Danish Port of Thyborøn
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Vestas has completed the installation of its V236-15.0 MW offshore wind turbine in the Port of Thyborøn in Denmark, only three months after the port ordered the company’s flagship model.
This is the first paragraph.
On 8 June, the wind turbine produced its first kWh of power, a crucial step in the final verification campaign, Vestas said in a social media post.
I suspect that soon, Vestas will be accepting orders for these large turbines.
RWE Orders 15 MW Nordseecluster Offshore Wind Turbines At Vestas
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Vestas has now revealed the name of the project and the client for a conditional contract the company signed in May as an unconditional order came in from RWE for the first phase of its 1.6 GW Nordseecluster offshore wind development in Germany.
This is the first paragraph.
The Denmark-based wind turbine OEM has received a firm order for 44 of its V236-15.0 MW offshore wind turbines for the 660 MW Nordseecluster A, the first phase of RWE’s two-phased Nordseecluster project in Germany.
Note.
- The V236-15.0 MW offshore wind turbine would appear to be Vesta’s largest turbine.
- On the Internet RWE’s Norfolk Vanguard West wind farm is shown as using the same turbine.
Does this mean that the Vestas V236-15.0 MW offshore wind turbine, is now RWE’s standard offshore turbine? This would surely have manufacturing, installation, operation and maintenance advantages.
These wind farms in the UK could use the V236-15.0 MW offshore wind turbines.
- Norfolk Boreas – 1380 MW – 92 turbines
- Norfolk Vanguard East – 1380 MW – 92 turbines
- Norfolk Vanguard West – 1380 MW – 92 turbines
- Dogger Bank South – 3000 MW – 200 turbines
- Awel y Môr – Up to 1100 MW – 73 turbines
- Five Estuaries – up to 1185 MW – 79 turbines
- North Falls – up to 504 MW – 34 turbines
Notes.
- The capacity us as sown on the RWE web site for each wind farm.
- The turbine numbers assume 15 MW turbines.
- The total capacity is 9929 MW.
- The number of turbines is 662.
The Nordseecluster will generate 1600 MW from 107 turbines.
Conclusion
I don’t see any reason, why all these wind farms couldn’t use the V236-15.0 MW offshore wind turbines.
UK Infrastructure Bank, Centrica & Partners Invest £300M in Highview Power Clean Energy Storage Programme To Boost UK’s Energy Security
The title of this post, is the same as that of this news item from Highview Power.
This is the sub-heading.
Highview Power kickstarts its multi-billion pound renewable energy programme to accelerate the UK’s transition to net zero in Carrington, Manchester.
These three paragraphs outline the investment.
Highview Power has secured the backing of the UK Infrastructure Bank and the energy industry leader Centrica with a £300 million investment for the first commercial-scale liquid air energy storage (LAES) plant in the UK.
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.
The investment will enable the construction of one of the world’s largest long duration energy storage (LDES) facilities in Carrington, Manchester, using Highview Power’s proprietary LAES technology. Once complete, it will have a storage capacity of 300 MWh and an output power of 50 MWs per hour for six hours. Construction will begin on the site immediately, with the facility operational in early 2026, supporting over 700 jobs in construction and the supply chain.
Note.
- The backers are of a high quality.
- The Carrington LDES appears to be a 50 MW/300 MWh battery.
It finally looks like Highview Power is on its way.
These are my thoughts on the rest of news item.
Centrica’s Involvement
This paragraph talks about Centrica’s involvement.
Energy leader Centrica comes on board as Highview Power’s strategic partner and a key player in the UK’s energy transition, supporting Carrington and the accelerated roll-out of the technology in the UK through a £70 million investment. The programme will set the bar for storage energy systems around the world, positioning the UK as the global leader in energy storage and flexibility.
I suspect that Centrica have an application in mind.
In Centrica Business Solutions Begins Work On 20MW Hydrogen-Ready Peaker In Redditch, I talk about how Centrica is updating an old peaker plant.
In the related post I refer to this news item from Centrica Business Systems.
This paragraph in the Centrica Business Systems news item, outlines Centrica’s plans.
The Redditch peaking plant is part of Centrica’s plans to deliver around 1GW of flexible energy assets, that includes the redevelopment of several legacy-owned power stations, including the transformation of the former Brigg Power Station in Lincolnshire into a battery storage asset and the first plant in the UK to be part fuelled by hydrogen.
As Redditch power station is only 20 MW, Centrica could be thinking of around fifty assets of a similar size.
It seems to me, that some of these assets could be Highview Power’s LDES batteries of an appropriate size. They may even be paired with a wind or solar farm.
Larger Systems
Highview Power’s news item, also has this paragraph.
Highview Power will now also commence planning on the next four larger scale 2.5 GWh facilities (with a total anticipated investment of £3 billion). Located at strategic sites across the UK, these will ensure a fast roll-out of the technology to align with UK LDES support mechanisms and enable the ESO’s Future Energy Scenario Plans.
Elsewhere on their web site, Highview Power say this about their 2.5 GWh facilities.
Highview Power’s next projects will be located in Scotland and the North East and each will be 200MW/2.5GWh capacity. These will be located on the national transmission network where the wind is being generated and therefore will enable these regions to unleash their untapped renewable energy potential and store excess wind power at scale.
So will the four larger systems have a 200MW/2.5GWh capacity?
They could, but 200 MW may not be an appropriate output for the location. Or a longer duration may be needed.
Highview Power’s design gives the flexibility to design a system, that meets each application.
Working With National Grid
Highview Power’s news item, also has this sentence.
Highview Power’s technology will also provide stability services to the National Grid, which will allow for the long-term replacement of fossil fuel-based power plants for system support.
Highview Power’s technology is also an alternative to Battery Energy Storage Systems (BESS) of a similar capacity.
How does Highview Power’s technology compare with the best lithium-ion systems on price, performance and reliability?
Curtailment Of Wind Farms
Highview Power’s news item, also has these two paragraphs.
This storage will help reduce curtailment costs – which is significant as Britain spent £800m in 2023 to turn off wind farms.
Highview Power aims to accelerate the roll-out of its larger facilities across the UK by 2035 in line with one of National Grid’s target scenario forecasts of a 2 GW requirement from LAES, which would represent nearly 20% of the UK’s long duration energy storage needs. By capturing and storing excess renewable energy, which is now the cheapest form of electricity, storage can help keep energy costs from spiralling, and power Britain’s homes with 24/7 renewable clean energy.
I can see several wind farms, that are regularly curtailed would have a Highview Power battery installed at their onshore substation.
Receently, I wrote Grid Powers Up With One Of Europe’s Biggest Battery Storage Sites, which described how Ørsted are installing a 300 MW/600 MWh Battery Energy Storage Systems (BESS) at Swardeston substation, where Hornsea Three connects to the grid.
I would suspect that the purpose of the battery is to avoid turning off the wind farm.
Would a Highview Power battery be better value?
What’s In It For Rio Tinto?
I can understand, why most companies are investing, but Rio Tinto are a mining company. My only thought is that they have a lot of redundant holes in the ground, that cost them a lot of money and by the use of Highview Power’s technology, they can be turned into productive assets.
Collateral Benefits
Highview Power’s news item, also has this paragraph.
Beyond contributing to the UK’s energy security by reducing the intermittency of renewables, Highview Power’s infrastructure programme will make a major contribution to the UK economy, requiring in excess of £9 billion investment in energy storage infrastructure over the next 10 years – with the potential to support over 6,000 jobs and generate billions of pounds in value add to the economy. It will also contribute materially to increasing utilisation of green energy generation, reducing energy bills for consumers and providing significantly improved energy stability and security.
If Highview Power can do that for the UK, what can it do for other countries?
No wonder companies of the quality of Centrica, Rio Tinto and Goldman Sachs are investing.

Grid Powers Up With One Of Europe’s Biggest Battery Storage Sites
The title of this post, is the same as that of this article in The Times.
This is the sub-heading.
Orsted’s huge facility in Norfolk will store energy generated by its offshore wind farm
These three paragraphs give more details of the project.
The world’s largest developer of offshore wind farms is planning to build a vast battery storage facility near Norwich.
Orsted will install the energy storage system, which will be one of the largest in Europe, on the same site as the onshore converter station for its Hornsea 3 wind farm in Swardeston, Norfolk.
The project will store energy generated by Hornsea 3 when weather conditions are windy and when electricity supply exceeds demand so that it can be discharged later to help to balance the nation’s electricity grid.
Note.
- There is also a visualisation and a map.
- Tesla batteries will be used.
- The The battery will have an output of 300 MW, with a capacity of 600 MWh. So it is another two-hour BESS.
- It should be operational in 2026.
- The battery is on a 35-acre site.
- Cost is given as £8.5 billion, but that would appear to include the 2852 MW Hornsea 3 wind farm.
The BBC is reporting that local residents are worried about fire safety.
I have some thoughts of my own.
The Location Of The Swardeston Substation
This Google Map shows the location of the Swardeston substation, which will also host the Swardeston BESS.
Note.
- The East-West road is the A 47 Norwich by-pass.
- Norwich is to the North of the by-pass.
- Just to the left-centre of the map, the main A 140 road runs between Norwich and Ipswich, which has a junction with the A 47.
- The A 140 passes through the village of Dunston, which is to the East of the National Grid sibstation, which will host the connection to the Hornsea Three wind farm.
This second Google Map shows the A 140 in detail from the junction to the A 47 to the Swardeston substation.
Note.
- The Swardeston substation is on a substantial site.
- The Norwich to Tilbury transmission line will have its Northern end at Swardeston substation.
- Once the infrastructure is complete at Swardeston substation, Hornsea Three wind farm will be connected to the electricity infrastructure around London.
There would appear to be plenty of space at the site for all National Grid’s plans.
Capital Cost Compared To Big Nuclear
Hornsea Three is a 2852 MW wind farm, that will cost with the battery and a few extras £8.5 billion or around around £ 3 billion per gigawatt.
Hinckley Point C on the other hand will cost between £ 31-35 billion or £ 9.5-10.7 billion per gigawatt.
Conclusion
National Grid would appear to be using a BESS at Swardeston substation to improve the reliability and integrity of the Hornsea Three wind farm.
How many other big batteries will be placed, where large wind farms connect to the National Grid?
As an Electrical and Control Engineer, I certainly, believe that energy storage at major substations, is a proven way to improve the grid.
