Does Being Widowed Lower Your B12?
I asked Google AI, the title of this post and received this answer.
Widowhood does not directly cause a biological decrease in B12, but it is often associated with lifestyle changes and stressors—such as depression, loss of appetite, and reduced nutritional intake—that can lead to a lower intake of Vitamin B12.
Key points regarding the connection:
Nutritional Risk: Research suggests that older adults who are widowed or depressed may have lower intakes of various nutrients, including Vitamin B12.
Depression Link: Depression, which is common in bereavement, is significantly associated with lower plasma levels of vitamin B12.
“Undernourishment” Factor: Studies indicate that widowed individuals are frequently represented in groups at high risk for undernutrition, which can contribute to nutrient deficiencies.
Lifestyle Changes: The transition to widowhood often involves a loss of partner support, leading to poorer nutritional habits and neglect of self-care.
While being widowed is not a direct metabolic cause, it is a significant risk factor for conditions that lead to B12 deficiency in older adults.
I certainly, eat less Vitamin B12, than before my wife died, as when we had a meal in a certain pub in Suffolk or Carluccio’s, I always had calves liver or fegato.
Ocean Winds Enters Lease Agreement With Crown Estate For 1.5 GW Celtic Sea Floating Wind Project
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Ocean Winds has entered into an agreement for lease with the Crown Estate for a 1.5 GW floating offshore wind project, for which the developer secured a site in the Round 5 seabed auction last year.
These two paragraphs add detail to the story.
Offshore Wind Leasing Round 5, the UK’s first dedicated floating wind seabed leasing round, was launched in February 2024, offering three areas. In June 2025, the Crown Estate announced Equinor and Gwynt Glas, a joint venture between EDF and ESB, as preferred developers for two project sites and said it was working to ensure the delivery of the full potential capacity of Round 5, which is up to 4.5 GW.
Equinor and Gwynt Glas entered into lease agreements for their floating wind projects in October 2025 and, the following month, the Crown Estate said Ocean Winds had secured the third floating offshore wind site in the Celtic Sea.
This map shows the three wind farms, that make up the Glynt Glas wind farm.
Note.
- It is expected to be built from and connect to the grid at Port Talbot in South Wales.
- The three sites are expected to be commissioned by the early-to-mid 2030s.
- The elongated white dot to the East of the wind farms would appear to be Lundy Island.
- The large bay to the North of Lundy is Carmarthen Bay with Caldey Island at its West end and Llanelli on its East.
- The Gower separates Swansea Bay from Carmarthen Bay.
This Google Map shows the Bristol Channel from the wind farms in the West to Cardiff and Hinkley Point.
Note.
- Along the North coast of the Bristol Channel, working from West to East, my 78-year-old eyes can pick out Milford Haven, Pembroke, Caldey Island, Tenby, Llanelli, Swansea, Port Talbot, Porthcawl, BridgendCaerphilly, Cardiff and Newport.
- Coming back along the South Coast, I can see Weston-super-Mare, Hinkley Point C and the tip of Lundy Island in line with Tenby.
- The three sections of Glynt Glas will each generate 1.5 GW, making a total of 4.5 GW.
- Hinkley Point C when completed, will be a 3.26 GW nuclear power station.
- There is also a 2.2 GW gas-fired power station at Pembroke.
Nearly 8 GW of renewable electricity should be enough to convert Port Talbot steelworks to the manufacture of green steel.
How Much Wind Power Is Planned For The Western Approaches?
I asked Google AI, the title of this section and received this answer.
The UK has a target of 50 GW of offshore wind by 2030, with significant projects planned for the Celtic Sea (part of the Western Approaches), which is a key area for 5 GW of floating wind. Total UK offshore wind pipeline capacity exceeds 93 GW, with major developments in this region focusing on floating technology.
Key details regarding wind power in the Western Approaches (specifically the Celtic Sea) include:
Celtic Sea Developments: The area is a primary focus for floating wind projects, designed to capitalize on deep-water potential, with 5 GW of floating wind expected to be deployed across the UK by 2030.
Pipeline and Capacity: The total UK pipeline for offshore wind, which includes the Western Approaches, is 93 GW, and the government is aiming for 43-50 GW of installed offshore capacity by 2030.
Project Status: The region is expected to benefit from the Crown Estate’s leasing rounds aimed at accelerating floating wind, with 15.4 GW of new projects submitted across the UK in 2024.
Wales/South West England Context: Wales has 1.4 GW of projects in the pre-application stage, with some potential for developments off the South West coast.
For more detailed information on specific projects and their development status, you can visit the RenewableUK website and RenewableUK website.
It looks like about 20 GW of offshore wind could be installed in the Western Approaches.
If You Lack Vitamin B12 Is It Sensible To Limit Alcohol?
I asked Google AI, the title of this post and received this answer.
Damages Absorption: Alcohol irritates the lining of the stomach and intestines, which hinders the digestive system’s ability to absorb Vitamin B12 from food or supplements.
Reduces Storage: B12 is stored in the liver. Chronic alcohol use can cause liver damage and inflammation, reducing the liver’s ability to store and release B12 when needed.
Impairs Function: Even moderate amounts of alcohol (one or two drinks a day) can interfere with B vitamin levels.
Increases Deficiency Risk: Research indicates that B12 deficiency is common in individuals who consume high amounts of alcohol.
Severe Symptoms: Increased fatigue, neurological issues (numbness, tingling), and cognitive problems.
Irreversible Damage: Long-term, unaddressed deficiency can lead to permanent nerve damage or severe anemia.
Recommended Steps:
Limit or Stop Alcohol: Drastically reducing alcohol intake allows the digestive system to recover and improves absorption.
Supplementation: If you are treating a deficiency, your doctor may recommend B12 supplements (pills, nasal sprays, or injections).
Dietary Changes: Increase consumption of B12-rich foods like red meat, fish, poultry, eggs, and dairy, or eat fortified foods.
How Much Electricity Do You Need To Charge A Garage Full Of Electric Buses?
Consider.
- A couple of years ago, I had a long discussion and a few beers with three managers of bus garages.
- In First Bus To Launch 1MW BESS Unit In Hampshire, Aberdeen To Follow, I talk about a specialist battery to charge buses.
- In Is Sumitomo Heavy Industries Highview Power Energy Storage System On line At Hiroshima?, I talk about an efficient, renewable power supply for an LNG Terminal.
I asked Google AI the question in the title of this post and received this comprehensive answer.
Charging a full garage of electric buses requires massive amounts of electricity, with typical, non-optimized charging for a 100-bus depot capable of drawing nearly 10 megawatts (MW) of power. To put this into perspective, a 100-bus depot might require roughly 150 Megawatt-hours (MWh) of energy to recharge over an eight-hour night.
Key Factors and Energy Requirements
Energy Consumption per Bus: A typical electric bus has a battery capacity between 300-500 kWh. Energy consumption averages around 1.11 to 1.35 kWh/km, with higher consumption in winter or with heavy A/C use.
Total Depot Power: For a 100-bus depot, power requirements can reach 10 MW, equivalent to the power output of a small hydroelectric dam.
Optimal Charging: Using smart charging, a 100-bus depot can reduce its peak demand to around 4 MW.
Daily Usage: A single, large electric bus can consume up to 500 kWh per day, with daily demand ranging from 189 to 231 kWh for typical operations.
Infrastructure and Grid Considerations
Charging Infrastructure: Depots often use 40 kW to 250 kW chargers, with 100 kW common for overnight charging.
Grid Capacity: A 34-bus depot might require a new 1000kVA transformer to handle the load.
Voltage: 11,000 volts may be required to power new substations, which are then stepped down to 400 volts for charging.
Operational Factors Affecting Energy Need
Heating and Cooling: Cold weather can increase energy consumption by up to 45% (due to electric heating).
Driving Style: Inefficient driving can increase energy consumption by 0.24 kWh/km above average.
Regenerative Braking: This can recover 37–40% of energy for 40-60 ft buses.
Cost Implications
Energy Bills: A 100-bus depot can incur monthly energy bills between $112,000 and $515,000 without optimization.
Cost Savings: Electric buses are generally cheaper to fuel, costing ~£0.21/mile compared to £0.49/mile for diesel.
Could A System Based On The Sumitomo/Highview Power System At Hiroshima Charge Electric Buses?
The optimal charging figure for a 100-bus garage would appear to be in the region of 4-5 MW.
In Is Sumitomo Heavy Industries Highview Power Energy Storage System On line At Hiroshima?, I state, that it looks like Highview Power’s CRYOBattery™ at the heart of the system has a capacity of 5 MW/20 MWh.
I also state in the post, that the Hiroshima facility is designed to support grid stability and enhance renewable energy integration.
Does this all mean that if you can install enough solar panels on the roof of the garage or perhaps a wind turbine nearby, that you can have buses substantially powered by the sun and wind.
Chicago would just love wind-powered buses!
Is Sumitomo Heavy Industries Highview Power Energy Storage System On Line At Hiroshima?
From some work I did at ICI in the 1970s on a PACE231R analog computer, I believe that Highview Power may have an extremely promising way of storing energy.
The Highview Power web site talks of Sumitomo Heavy Industries, who are building one of Highview’s batteries at Hiroshima in Japan.
So I asked Google AI the question in the title of this post and received this comprehensive answer.
Yes, the Sumitomo Heavy Industries (SHI) Highview Power liquid air energy storage (LAES) commercial demonstration plant in Hatsukaichi, Hiroshima, is operational, having commenced operations on December 1, 2025.
Key details about the plant:Location: Within the Hiroshima Gas Hatsukaichi LNG Terminal.Capacity: 5 MW output with 4-hour storage (4 MW charging).Technology: Uses Highview Power’s CRYOBattery™ technology, specifically utilizing waste cold from the adjacent LNG terminal to improve efficiency.Role: The facility is designed to support grid stability and enhance renewable energy integration.A completion ceremony for the project was held on December 9, 2025. This news item from Sumitomo Heavy Industries gives more details.This paragraph describes Liquid Air Energy Storage or (LAES).
- It looks like the battery has a capacity of 5 MW/20 MWh.
- As it talks about using waste cold, this looks to be a very professionally-designed specialist application.
- But surely, that would be expected from a company like Sumitomo Heavy Industries.
There are hundreds of LNG terminals globally, with significant growth driven by over 300 projects (roughly 177 import/regasification and 124 export/liquefaction) expected between 2025 and 2030. In 2023, there were 22 countries with active liquefaction (export) capacity, while Europe alone operates roughly 28 large-scale terminals, supplemented by a rapidly expanding fleet of FSRUs.Export Capacity: In 2023, global liquefaction capacity was 472 million tonnes per annum (mtpa), with top exporters being Australia, the U.S., and Qatar.Expansion: By 2027, 52 new liquefaction terminals are expected to commence operations.Import Growth: European regasification capacity is expanding, with major terminals in Spain, France, Italy, and new additions in Germany and other nations.U.S. Infrastructure: The U.S. alone has more than 170 LNG facilities performing various services.
- They are listed in this Wikipedia entry.
- There are around thirty in Japan alone.
- Will Centrica add a 5 MW /20 MWh Highview Power battery to their Grain LNG Terminal?
- Each facility installed is claimed to be designed to support grid stability and enhance renewable energy integration, so the last part must cut carbon emissions.
Yes, several major chemical engineering and industrial processes generate significant amounts of “waste cold” (low-grade thermal energy or cryogenic energy) that is often discarded. While the chemical industry conventionally focuses on recovering waste heat, recovering waste cold is becoming increasingly popular for improving energy efficiency, particularly in cryogenic processes.

How Much Pumped Storage Hydro Will Be Operational In The UK By 2030?
Pumped Storage Hydro is the Bank of England-standard for energy storage.
I asked Google AI, the question in the title of this post and received this answer.
The UK currently has approximately 3 GW (roughly 26-28 GWh) of operational pumped storage hydro (PSH) capacity. By 2030, this capacity is expected to increase, driven by new projects in the pipeline that aim to meet a government goal of up to 8 GW of long-duration energy storage by that year.
Key Projects Expected Online by 2030-2031:
Coire Glas (SSE): A major project in Scotland with a planned capacity of 1.3 GW / 30 GWh, expected to be operational around 2030–31.
Cruachan Expansion (Drax): A 600MW plant in Scotland that has received approval, with construction expected to contribute to the 2030 goal.
Glenmuckloch: Projected to be operational by 2029. In
Other Developments:
Total Pipeline: Developers have identified up to 10 GW of potential projects in the Scottish Highlands and Wales, though not all will be operational by 2030.
Future Growth: The total installed capacity of PSH is expected to grow significantly, with one projection suggesting a rise from 26.7 GWh currently to over 122 GWh by 2034.
To support these projects, the UK government has confirmed a “cap and floor” investment framework to stimulate development of long-duration energy storage (LDES).
For a relatively small island we do seem to be an ideal place to develop pumped storage hydro!
The Coire Glas Pumped Storage Scheme
In The Coire Glas Pumped Storage Scheme, I give more details of this scheme.
The Glenmuckloch Pumped Storage Scheme
In The Glenmuckloch Pumped Storage Scheme, I give more details of this scheme, which is based on a disused open cast coal mine.
Addition Of Pumped Storage Hydro By 2030
This looks to be around 5 GW, but it is just a foretaste of the shape of things to come!
Could The Settle And Carlisle Be Used As A More Formal Route?
In June 2021, I wrote Through Settle And Carlisle Service Under Consideration, which starts like this.
The title of this post, is the same as that of an article in the June 2021 Edition of Modern Railways.
This is the first paragraph.
Plans for a new Leeds to Glasgow through service via the Settle and Carlisle line are being developed, with CrossCountry and the Department for Transport starting to look at the possible scheme.
It sounds like a sensible idea to me.
The article also suggests the following.
- CrossCountry is a possible operator.
- CrossCountry are keen to improve services between Leeds and Glasgow
- The trains could be InterCity 125s, freed up, by a the arrival of Class 221 trains from Avanti West Coast, when they receive their new Class 805 trains.
- Maintenance of the trains wouldn’t be a problem, as this could be done at Neville Hill in Leeds or Craigentinny in Edinburgh.
- Services could start in December 2023.
But nothing more has been heard.
However some things have happened.
The Settle And Carlisle Has Become A Popular Charter Route
Google AI gave me this paragraph.
The Settle and Carlisle line is an extremely popular, premier route for heritage rail charters, steam excursions, and luxury rail tours in the UK, often operating at full capacity. Renowned for its scenic 72-mile journey through the Yorkshire Dales and Pennines, it features iconic structures like the Ribblehead Viaduct.
I have also written these posts about charters on the Settle and Carlisle Line.
Scheduled Steam-Hauled Services For the Settle And Carlisle Railway
Rail Operator Crosses Line For First Time In Years
‘Staycation Express’ To Return Along Full Length of S & C
It doesn’t appear that the numbers of charter trains are showing any sign of decrease.
LNER Has Ordered Class 897 Trains
When LNER took over the East Coast Main Line services, they had six main classes of trains.
- Five-car Class 800/1 bi-mode trains
- Nine-car Class 800/2 bi-mode trains
- Five-car Class 801/1 electric trains
- Nine-car Class 801/2 electric trains
- Seven-car InterCity225 trains
- Nine-car InterCity225 trains
Note.
- The five-car trains can run in pairs as ten-car trains.
- The Class 800 and Class 801 trains can run to destinations, that lack full electrification using diesel power where needed.
- Hitachi are developing battery-power for rail routes without electrification.
In 2023 to replace the InterCity225 trains ten ten-car Class 897 tri-mode trains were ordered from CAF, which will soon be in service, over all LNER’s network.
LNER Has Fully Electrified And Unelectrified Destinations
LNER’s current destinations, that are fully electrified to King’s Cross include.
- Bradford Forster Square
- Berwick on Tweed
- Darlington
- Doncaster
- Durham
- Edinburgh Haymarket
- Edinburgh Waverley
- Grantham
- Keithley
- Leeds
- Newark Northgate
- Newcastle
- Peterborough
- Retford
- Shipley
- Skipton
- Stevenage
- Wakefield Westgate
- York
Whilst those are not fully electrified include.
- Aberdeen
- Cleethorpes
- Dundee
- Grimsby Town
- Harrogate
- Huddersfield
- Horsforth
- Hull
- Inverness
- Lincoln
- Middlesbrough
- Sheffield
- Sunderland
- Thornaby
- Worksop
Note.
- Other destinations can be added as required.
- I suspect, that Class 897 trains will be able to approach many stations without electrification on battery power alone.
- Staff and Passengers would probably like underground stations like Sunderland to be worked on batteries alone.
The Class 800 bi-mode, the Class 801 electric and the Class 897 tri-mode trains will give LNER a very flexible fleet.
Onward To Skipton, Carlisle and Glasgow Central And Edinburgh From Bradford Forster Square
I wonder is someone has realised that the Class 897 trains could use their tri-mode capabilities to invade Scotland?
This OpenRailwayMap shows the railways between the Scottish Lowlands and northern England.
Note.
- Red tracks are electrified.
- Black tracks are not.
- The blue arrow in the middle of the map indicates Carlisle.
- The red track going North-South through Carlisle is the West Coast Main Line.
- The black track going South from Carlisle is the Settle and Carlisle Line.
- Where it turns red is at Skipton station and the electrification can power the train to Bradford Foster Square, Doncaster, Leeds or Sheffield stations.
- The West Coast Main Line splits North of Carlisle and electrified trains can reach either Glasgow Central in the West or Edinburgh Haymarket or Waverley in the East.
- The black track going North-South between Carlisle and Glasgow via Dumfries is the Glasgow South Western Line, which can be used as a diversionary route by some trains with a self-powered capability.
The Settle and Carlisle Line certainly makes Anglo-Scottish routes more robust and flexible when there is bad weather, engineering works or overhead wire or signalling failures.
Will Class 897 Trains Be Able To Run On The Settle And Carlisle Line?
I asked Google AI this question and it gave this answer.
Yes LNER’s new Class 897 tri-mode trains (scheduled for introduction from 2027) will be able to run on the Settle and Carlisle line. As tri-mode electro-diesel multiple units, these 10-car trains are designed to operate across the entire LNER network, utilizing electric, diesel, or battery power to manage non-electrified routes like this, providing a modern alternative to older, diesel-only fleets.
Key details regarding Class 897 on the Settle and Carlisle Line:
Tri-mode Capability: These trains can run on electric, diesel, or battery power, making them highly versatile for non-electrified, scenic, or challenging routes.
Operating Strategy: The trains are designed for flexibility and can be used across the LNER network, which includes routes connecting to Scotland via the West Coast Main Line (WCML) or through services from Leeds.Upgrading Service: They will replace the 40-year-old InterCity 225 fleet, offering a more environmentally friendly, modern alternative to current diesel bi-modes, such as the Class 800/802.
The route is a major, yet challenging, rail line featuring 20 viaducts and 14 tunnels, making it suitable for modern, versatile train sets.
I also believe that running Class 897 trains between Yorkshire and Glasgow offers opportunities to run new services, that will appeal to both travellers and rail operators.
Does The UK Need More Passenger Rail Capacity Between Yorkshire And Glasgow?
I asked Google AI this question and it gave this answer.
Yes, the UK requires more passenger rail capacity between Yorkshire and Glasgow due to severe overcrowding and forecasted demand growth. Major routes like the East Coast Main Line (ECML) and West Coast Main Line (WCML) are, or will soon be, at maximum capacity. Key constraints include infrastructure limitations and the need for better Scotland-England connectivity.
Key insights on this need:
Capacity Constraints: The WCML, particularly at its southern end, is already effectively full, with limited capacity for additional, longer trains. Similarly, the ECML is experiencing significant overcrowding.
Growing Demand: Passenger demand for long-distance rail travel continues to rise, with significant increases noted in journeys between Scotland and other regions.
Infrastructure Issues: Constraints include steep inclines, tight curves, and the need to mix passenger and freight traffic, particularly on the West Coast route.
Proposed Solutions: While some improvements are planned, such as Lumo extending services to Glasgow, the Integrated Rail Plan (IRP) focuses on capacity enhancements in the North/Midlands.
Strategic Need: Enhanced, high-speed connections are considered essential for long-term economic integration and to prevent increased air travel/emissions.
The great advantage of the route, is that is already in place.
Can The Settle And Carlisle Line Handle Planned Diversions?
Can The Settle And Carlisle Line Handle The Caledonian Sleeper?
I asked Google AI this question and it gave this answer.
The Settle-Carlisle line is not a standard route for the Caledonian Sleeper, which typically travels via the West Coast Main Line (WCML) to Edinburgh, Glasgow, and beyond. While the line is a scenic, double-track route with significant infrastructure, it is generally used for local services and freight, not long-distance, heavy sleeper trains.
Key Considerations:
Route: The Caledonian Sleeper operates on the West Coast Main Line, serving destinations like Edinburgh, Glasgow, Aberdeen, Inverness, and Fort William.
Capacity & Infrastructure: While the Settle-Carlisle line has major structures like the Ribblehead Viaduct, it is not the primary route for high-speed or overnight sleeper services.
Operational Normal: The sleeper service splits into portions at Edinburgh, and does not regularly operate via the Settle-Carlisle line.
In short, the Settle-Carlisle line is not designed for or used by the Caledonian Sleeper, which operates via the West Coast Main Line.
But it does appear, that in the past some sleeper trains have used it.
How Many Freight Trains Use the Settle And Carlisle Line In A Typical Day?
This article on the BBC is entitled Settle To Carlisle line: Shortage of trains ‘Hampering Growth’, says this about the number of trains.
From only two trains a day in the 1980s the Settle and Carlisle line now sees 14 passenger and 18 freight services a day.
That is progress!
New Baltic Sea Interconnector On Horizon As Lithuania, Latvia, and Germany Plan Cross-Border Link
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Lithuania, Latvia, and Germany are planning a joint offshore interconnector that would enable electricity trading between the Baltic countries and Germany and allow for the integration of up to 2 GW of offshore wind capacity in Lithuania and Latvia
These first two paragraphs add more detail to the article.
The energy ministers of the three countries signed a joint declaration of intent on 18 February, paving the way for the development of the Baltic-German PowerLink interconnector, which would, in addition to electricity trading and offshore wind capacity integration, also enable the expansion of onshore renewable energy capacity.
The Lithuanian, Latvian, and German transmission system operators (TSOs) – Litgrid, Augstsprieguma tīkls and 50Hertz – agreed to assess the feasibility of the hybrid electricity interconnection.
As Germany, has the following connections under development in the West.
- AquaVentus to Aberdeen, Humberside, Denmark, Norway and The Netherlands.
- NeuConnect to the Isle of Grain In England.
- GriffinLink, which is an offshore link to England.
The Germans seem to be putting themselves at the centre of an energy distribution system, that has the capability to stabilise European and UK electricity for thousands of years. Especially, if the network grows to include more countries.
This paragraph says this about the Baltic-German PowerLink project.
The Baltic-German PowerLink project concept developed by Litgrid, Augstsprieguma tīkls, and 50Hertz includes a 2 GW, approximately 600 kilometres long hybrid offshore connection, with the connection point in the Baltic States planned to be on the border between Lithuania and Latvia. The exact location is to be determined after technical studies.
Note.
- The interconnectors may be long, but they are not longer than anything built successfully before in European waters.
- The UK and the Island of Ireland are well-linked.
- There would appear to be no need for challenging projects like the Morocco-UK Power Project
I suspect that Germany will get the energy it needs and the British Isles will get a nice little earner.
If Europe is generating large amounts of wind and solar energy with its variable output it will need lots of energy storage.
What Countries Have The Terrain For Pumped Storage Hydro In Europe?
I asked Google AI and received this answer.
Key countries with ideal, high-elevation terrain and significant existing or planned capacity include:
Alpine Region (The Heart of European Pumped Storage):
Switzerland: Extremely high capacity due to steep, mountainous landscapes and significant water sources, hosting the world’s oldest working pumped storage plant.
Austria: Heavily mountainous, it is a major player in PSH expansion and modernization.
France: Home to one of Europe’s largest, the Grand Maison hydroelectric power station.
Italy: Holds high capacity with numerous planned projects.
Germany: Strong existing infrastructure.
Southern Europe:
Spain: Features some of Europe’s largest plants (e.g., La Muela/Cortes-La Muela).
Portugal: Significant recent investment in large-scale projects like the Tâmega complex.
Other Potential Areas:
Norway: High potential due to its mountainous, water-rich terrain.
United Kingdom: High project volume currently under construction.
Balkans & Central Europe:
Countries like Bulgaria, Romania, and the Czech Republic have suitable terrain for further development.
These countries benefit from significant hydraulic head (steep drop) and natural or artificial reservoir potential, making them ideal for storing energy for peak consumption hours.
Note.
- As expected, the Alpine region is Top of the League.
- The UK is holding its own despite its small mountains.
- There is a lot of potential to be developed.
But then Electric Mountain in Snowdonia is certainly at the top table of pumped storage systems despite being built in the 1980s.
What Countries Have The Terrain For Hydrogen Storage In Europe?
I asked Google AI and received this answer.
Key European countries with suitable geological terrain—specifically salt caverns and depleted gas fields—for large-scale, underground hydrogen storage include Germany, the Netherlands, Denmark, the United Kingdom, and France. Other significant regions for storage potential include Spain, Hungary, and Austria, which are developing porous storage facilities.
Key Regions & Terrain Types:
Salt Caverns (North-Western Europe): Germany, the Netherlands, Denmark, France, and the UK have substantial salt deposits suitable for creating caverns, identified as cost-efficient for large-scale storage.
Depleted Gas Fields (Porous Rock): The Netherlands, Germany, and parts of Central/Southern Europe (Spain, Hungary) have significant capacity in existing porous storage, particularly in the North Sea region.
Specific Projects: Germany (Uniper’s Krummhörn project), Netherlands (HyStock), and France (HYPSTER at Etrez) are active, with Spain and Denmark emerging as major hydrogen hubs.
Capacity Potential: The Netherlands, for instance, holds massive potential (35-60 TWh) due to its offshore and onshore depleted fields.
Salt cavern projects, which offer high-deliverability storage, are heavily concentrated in the North-Western European industrial corridor.
I was lucky enough have a tour of ICI’s salt mine in Cheshire, when I worked there in the 1960s and I remember these facts from those days.
- There was enough salt in the ground under Cheshire to last several thousand years.
- Most salt was extracted from boreholes, for making chlorine using electrolysis and the Castner-Kellner process.
- Hydrogen was a by-product and much of it was mixed with coal gas to raise steam for the works.
The same technique used to make boreholes to extract the salt, is used to hollow caverns in the salt to store gases like hydrogen.
Once, when they were digging salt out of the salt mine at Winsford, a worker broke into an unmarked borehole and ICI nearly lost the mine because of the water rushing in.
Two stories stand out from the rescue of the mine.
- There was a need for dry clothes for all the workers, so ICI took a truck to Marks & Spencer in Northwich and emptied it of anything they might need. I was told the story enriched with plagues of locusts.
- A Ford Transit was found to have travelled a few thousand miles underground in axle deep salt slurry. Rather, than scrap it and buy another, it was offered back to Ford, who were delighted to swap it for a new one. I heard that Ford said, that the accelerated corrosion research would have taken many years, if done on the roads.
Always think out of the box.
Do British And German Offshore Wind Farm Generate Maximum Power At Different Times
In National Grid, TenneT Germany Launch GriffinLink, A First Of A Find Project To Maximise Offshore Wind, I discussed GriffinLink, which will be an offshore link between British and German offshore wind farms.
Somebody has asked me if wind farms are in phase with each other, as obviously this would effect how they perform and are are controlled.
So I asked Google AI, the question in the title of this post and received this reply.
Yes, British and German offshore wind farms often generate their maximum power at different times, although they are both located in the North Sea and share similar peak seasons. The variations in generation are driven by localized weather patterns, specifically the movement of low-pressure systems.
Key Differences in Generation Times:
Regional Weather Patterns: While North Sea wind farms are often closely correlated, significant differences arise when weather systems move from west to east. Wind often hits the UK’s North Sea sites first, meaning they may hit maximum generation capacity hours before German or Danish sites, which are further east.
Time of Day (Diurnal Differences): Because UK wind farms are located in the Irish Sea, the Scottish coast, and the North Sea, they can exhibit different diurnal (daily) peak times compared to German sites in the North Sea and Baltic Sea.
Seasonal Peaks: Both countries experience the highest output during winter months (e.g., December). However, during specific, localized, long-lasting high-pressure systems (“Dunkelflaute”), one country might experience a complete drop in wind while the other continues to produce, or vice versa.
Why They Differ:
Geography: The UK’s extensive, spread-out coastline (Irish Sea, Atlantic coast, North Sea) offers a different wind profile than the more concentrated German offshore projects in the North Sea and Baltic Sea.
Correlation Challenges: Research shows that while North Sea countries have similar wind profiles, there is not 100% correlation. Meteorological differences in how wind speeds behave across the North Sea allow for complementary production.
This difference is highly advantageous for European energy security, as it allows for the balancing of intermittent wind power across the region.
The conclusion from Google AI, is almost predicting that GriffinLink will be developed. From my experience of mathematical modelling the cost and financial benefits should be fairly easy to predict.
Will The UK And The Republic Of Ireland Link Their Offshore Wind Farms To Improve Efficiency?
This may seem an obvious idea, especially as UK and Republic of Ireland are heavily interconnected.
So I asked Google AI, the question in the title of this section and received this reply.
Yes, the United Kingdom and the Republic of Ireland are taking significant, active steps to link their offshore wind farms and electricity grids to improve efficiency, increase renewable energy production, and enhance energy security. Following a Memorandum of Understanding (MoU) signed in September 2023, the two countries are collaborating on developing subsea energy infrastructure in the Irish and Celtic Seas.
Here are the key details regarding this cooperation:
Deepened Collaboration: As of March 2025, the UK and Ireland are working on a new data-sharing arrangement to lay the groundwork for directly connecting offshore wind farms to each other’s national energy networks.
Offshore Hybrid Assets (OHAs): The plans include developing offshore hybrid assets, which are subsea cables that directly link offshore wind farms to both countries’ grids, reducing infrastructure costs and maximizing efficiency.
Subsea Mapping & Interconnection: Both nations are mapping the Celtic Sea to identify optimal locations for interconnectors and to improve the interoperability of their grids.
Existing & New Projects: While Ireland’s current interconnection to the UK is limited (approx. 500MW), capacity is planned to increase significantly. Specific projects like Mares Connect (linking North Wales and Ireland) are being developed to provide750MW of additional capacity.
Regional Cooperation: Ireland is also participating in the “Hamburg Declaration” (signed Jan 2026), joining the UK and other North Sea countries to commit to 300GW of offshore wind by 2050 through shared, regional infrastructure.
This cooperation aims to allow Ireland to export its surplus renewable energy during high generation, while benefiting from the UK’s robust grid during lower wind conditions.
Will The UK AndNorway Link Their Offshore Wind Farms To Improve Efficiency?
As we have interconnectors with Norway, I asked Google AI, the question in the title of this section and received this reply.
Yes, the UK and Norway are actively planning and implementing initiatives to link their offshore wind farms and electricity grids to improve efficiency, energy security, and grid balancing. Following a series of agreements, including a major pact in January 2026, the two countries are collaborating on “hybrid” projects that connect offshore wind sites directly to multiple countries.
It does look like that the co-operations between the UK and Germany, Norway and the Republic of Ireland are setting examples that should be copied all over the world.
But then, you should always follow the mathematics.
But somehow, I can’t see President Trump signing any windmill co-operation with his neighbours.
Does The UK Need More Passenger Rail Capacity Between London And Glasgow?
I asked Google AI this question and received this answer.
Yes, the UK requires more passenger rail capacity between London and Glasgow to meet growing demand and combat overcrowding, with key improvements and new services planned on the East Coast Main Line (ECML) through 2025. Despite previous capacity constraints on main routes, rail has overtaken air as the preferred mode of travel for these journeys, necessitating increased frequency.
Key details:
Capacity Expansion: The Office of Rail and Road (ORR) approved new services for late 2025, including Lumo extending London-Edinburgh services to Glasgow.
Growing Demand: Passenger numbers on West Coast routes showed significant growth, with a 29% increase in Glasgow-London travellers reported between 2013 and 2019.
Infrastructure Constraints: While demand increases, the ORR has rejected some service proposals due to insufficient capacity on the existing, congested lines.
Future Upgrades: HS2 is expected to improve connectivity, targeting reduced journey times to under 3 hours 40 minutes by 2033.
Sustainability Shift: Increased capacity supports shifting travellers from air to rail, reducing environmental impact.
I posed this question out of curiosity, but Google AI gave me, what I think is a well-reasoned answer.
