Apollo to Work On Celtic Sea Multi-Connection Offshore Substations

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

This is the sub-heading.

Celtic Sea Power has awarded the Aberdeen-based engineering consultants, Apollo, with the pre-FEED contract for the 400 MW Pembrokeshire Demonstration Zone Multi-connection Offshore Substation (PDZ MOS) and 2x 1 GW MOSs targeting The Crown Estate Refined Area of Search (RAoS) A offshore Wales

This is the first paragraph.

Located 19 kilometres off the Pembrokeshire coast, the PDZ MOS project is designed to allow offshore renewable energy technology developers easy access to a consented test site complete with a grid connection to prove their technology in the offshore environment.

Sounds like the sort of infrastructure that is needed, so you can tow up your experimental floating wind turbine, secure it and just plug it in.

National Grid Energise World’s First T-Pylons

The title of this post, is the same as that of this press release from National Grid.

These are the four bullet points.

  • Electricity is flowing to homes and businesses through the first new pylon design in the UK for nearly 100 years.
  • Major milestone in National Grid’s Hinkley Connection project to connect 6 million homes and businesses in the South West to home grown, low carbon energy.
  • The T-design, with a single pole and cross shaped arms, is around a third shorter than the traditional design with a smaller ground footprint.
  • The T-pylons, along with a new substation and underground cabling, are now incorporated into National Grid’s electricity transmission network delivering electricity in Somerset and across England and Wales.

This is the first paragraph.

National Grid has successfully energised 36 of the world’s first T-pylons between Bridgwater and Loxton in Somerset. The new shaped pylons have been constructed as part of the £900 million Hinkley Connection Project, a new 57 km high-voltage electricity line that will connect six million homes and businesses to new sources of home grown, low carbon energy and help the UK to meet its net zero by 2050 target.

There is a video in the press release, which is well worth a view.

  • The size of the pylons certainly reduces their visibility.
  • It appears there are seven cables on either side.

These pictures show the transmission lines to the Sizewell power station site.


  1. The lower height is very noticeable.
  2. There seem’s to be a lot more wires.
  3. I would assume, that the reduced number of components, reduces the cost of installation and maintenance.

The installation proved that even in the most mundane of applications, innovation can bring positive results.

The T-pylons are a design by Danish company; Bystrup.

This is the specification from their comprehensive web-page.

  • Power – 2 x 400 kV
  • Height – 35 metres / 114 feet
  • Units/km – 3  (5 units/mile)
  • Material – Hot-dip galvanised steel, painted
  • Assembly – On-site and quick – less than 10 parts
  • Installation – Simple monopile foundation
  • Production possible anywhere in the world
  • Developed – 2011-2014

They’ve also won several awards.

  • 1st prize in int. competition for RIBA
  • Nominated for the IET Innovation Award 2014
  • Gold Prize, CIGRE Seoul 2017
  • Award winner, UK Steel Awards (SSDA) 2017

I would hope to see more in the UK.

Call For Innovations In Offshore Wind – RWE Launches Global Innovation Competition 2023

The title of this post, is the same as that of this press release from RWE.

This is the sub-heading.

Solutions wanted in the domains of ecology, circularity and system integration – Deadline for submission is 17th of April 2023

This is the first paragraph.

RWE, one of the world leaders in offshore wind, has launched its second annual Innovation Competition. The company is looking for solutions in the domains of ecology, system integration and circularity in offshore wind. RWE is dedicated to exploring and supporting innovative solutions that can both accelerate the pace of deployment of offshore wind, as well as contribute to sustainable development of offshore wind farms worldwide.

As someone who explored the dynamics of towing out and erecting floating oil platforms in the 1970s, I don’t think my experience fits entering. But I’ll be thinking about something.

World’s First Offshore Vessel Charging System Completes Harbour Trials

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

This is the sub-heading.

MJR Power and Automation, together with Blackfish Engineering and Tidal Transit, have completed the harbour trials of the company’s platform-mounted automated offshore power and charging system.

Reading the article, this appears to be a very comprehensive system, that allows electric or hybrid wind farm servicing vessels to top up their batteries efficiently before returning to base.

Surely, it is better to do it this way by developing the charging network before bringing the battery and hybrid vessels into service.

UK Company Introduces Robotic Ecosystem For Offshore Wind Farm Inspections

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

This is the sub-heading.

Marshall Futureworx, the venture building and advanced technologies arm of Marshall of Cambridge, has unveiled plans to provide offshore wind farm inspection services using a resident robotic ecosystem.

These two paragraphs outline the system.

Lilypad is an ecosystem of multiple autonomous BVLOS (Beyond Visual Line of Sight) UAVs (Unmanned Aerial Vehicles) which utilise artificial intelligence and navigational sensors to provide dynamic and on-demand offshore inspection services, Marshall Futureworx said.

The UAVs are deployed from dedicated offshore charging stations and monitored by a single remote pilot stationed in an onshore command and control centre. Inspection data and reports are then transmitted back to the wind farm operators, which is said to enable faster, more frequent, reliable, and predictive maintenance scheduling and more effective utilisation of assets.

I can think of lots of uses for a system like this.

Floating Foundation For 15+ MW Offshore Wind Turbines Launches

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

This is the sub-heading.

Odfjell Oceanwind has launched the Deepsea Star™ harsh environment floating wind foundation designed to support wind turbines with a capacity of 15 MW and more.


  • Odfjell Oceanwind is a Norwegian company and has this web site.
  • This news item from Odfgell Oceanwind is entitled  Odfjell Oceanwind Launches The Deepsea Star™ 15MW Floating Wind Foundation and was published on the 28th of February, 2023.
  • The news item was the source of the article.
  • In the news item, one of the designers, explains some of the features.

I very much believe that ,my twenty-three-year-old self armed with ICI’s PACE 231-R would have had great fun examining the dynamic proiperties of a structure like this.

Activity Ramping Up On Irish Floating Wind Test Site

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

This is the sub-heading.

The Sustainable Energy Authority of Ireland (SEAI) is busy with bringing forward its Atlantic Marine Energy Test Site (AMETS), a floating wind and wave energy technology test site which has been in development for several years now. Along with offshore surveys scheduled for next month, SEIA has also commenced work on procuring an onshore substation and a floating LiDAR for AMETS.

It all sounds very professional.

The Atlantic Marine Energy Test Site will be located off Annagh Head in the West of Ireland. This Google Map shows the location of Annagh Head on the island of Ireland.

I do have a imperfect memory of a weekend of good hospitality and gourmet food at a hotel called the Cashel House Hotel to the West of Galway, but I can’t remember how C and I flew there. Did we fly to Knock or Shannon either using a scheduled airline or my Cessna 340 A?

All I can remember of the holiday, was that it was very windy at times and driving through Westport. So did we explore towards Annagh Head?

This Google Map shows a close-up of Annagh Head.

I suspect that Annagh Head is an ideal location to test floating wind and wave power.

There will also be good hospitality and airlinks to the UK and Europe.

In So Many Floating Wind Designs, So Few Test Sites – Norwegian METCentre Sold Out, I wrote about the shortage of test sites for wind power.

So perhaps, AMETS will help to fill the gap?

Skegness Wind Turbine Trial To Light Up Pier In UK First

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

This is the sub-heading.

A Lincolnshire seaside pier is being lit up at night with the help of a new mini wind turbine.

These are the first three paragraphs.

One of the 6ft (2m) vertical turbines has been installed on Skegness Pier with another fitted on a factory roof in Spalding.

They are able to capture wind from all directions without turning, making them low maintenance.

Both are made by Norwegian company Ventum Dynamics, which is testing the technology with local councils.

I believe it is one of those ideas, that proves the Sliced-Bread Theory of Innovation.

I have a few thoughts.


The design looks clean, modern and unobtrusive.

I don’t know what the noise level is like, but I suspect good design means, it could be fairly low.

I’ll just have to visit Skegness on a windy day, which won’t be a difficult thing to arrange.

Easy To Add To An Existing Or New Building

The Ventum web site has some good pictures.

From my flying experience, I suspect that the higher a turbine is mounted, the more power will be generated.

The only problem would be the heritage lobby.

This picture shows Oakwood station on the Piccadilly Line.


  1. The station is the second most Northerly on the line.
  2. It opened in 1933.
  3. It is a classic Charles Holden design.
  4. It is a Grade II* Listed building.
  5. The station is on top of a hill and has an elevation of 71 metres above sea level.

It might be the ideal place to put perhaps six turbines on the roof.

But would the heritage lobby allow it?

Remote Power

Teamed with a battery, they would be the ideal remote power solution for buildings and locations without a mains supply.


I used to part-own a finance company and feel that these turbines would be attractive to a finance company, if ethically sold.


I like them!

Entrion Wind Wins ScotWind Feasibility Deal For Its 100-Metre Depth Foundation Tech

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

This is the sub-heading.

Entrion Wind has been awarded a project to evaluate the feasibility of its patent-pending fully restrained platform (FRP) offshore wind foundation technology by a Scotwind developer.

Having worked on similar structures for reusable oil platforms in the 1970s, I reckon these FRP monopoles can be made to work.

The structures, I mathematically-modelled were for a company called Balaena Structures, that had been started by two Cambridge University engineering professors. The structures were about a hundred metres high and perhaps thirty metres in diameter.

They would have been built horizontally in the sort of dock, where you would build a supertanker and would have been floated into position horizontally. Water would then be let in to the cylinder and they would turn to the vertical.  From that position, they would be lowered to the sea-bed by adjusting the water in the cylinder. They had a method of holding the Balaena to the seabed, which relied mainly on the weight of the structure and what they called the gum-boot principle.

Sadly, they never sold any platforms and the company folded.

Until recently, you could find the expired patents on the Internet.

There’s more on Entrion Wind’s technology on this page on their web site.

Diversifying A US$200 billion Market: The Alternatives To Li-ion Batteries For Grid-Scale Energy Storage

The title of this post, is the same as that of this article on Energy Storage News.

This is the introductory paragraph.

The global need for grid-scale energy storage will rise rapidly in the coming years as the transition away from fossil fuels accelerates. Energy storage can help meet the need for reliability and resilience on the grid, but lithium-ion is not the only option, writes Oliver Warren of climate and ESG-focused investment bank and advisory group DAI Magister.

Oliver starts by saying we need to ramp up capacity.

According to the International Energy Agency (IEA), to decarbonise electricity globally the world’s energy storage capacity must increase by a factor of 40x+ by 2030, reaching a total of 700 GW, or around 25% of global electricity usage (23,000TWh per annum). For comparison, this would be like swelling the size of the UK’s land to that of the USA.

Similar to how “nobody ever gets fired for buying IBM”, lithium-ion holds a similar place in grid scale electrical storage today.

And just as IBM did in the last decades of the last century, the builders of lithium-ion will fight back.

He then lists the problems of grid-scale lithium-ion batteries.

  • Shortage of cobalt.
  • Toxic and polluting extraction of some much needed metals and rare earths from unstable countries.
  • Lack of capacity to load follow.
  • Limited lifespan.

He does suggest vehicle-to-grid can provide 7TWh of storage by 2030, but it has similar problems to lithium-ion grid scale batteries.

Finally, he covers these what he considers several viable methods of energy storage in detail.

He introduces them with this paragraph.

No single killer application or technology exists to get the job done. Diversification is key with success dependent on the wide-scale adoption of multiple grid-scale energy storage solutions.


  1. All systems are environmentally-friendly and use readily-available materials like air, water, sea-water, steel and concrete for their systems.
  2. The most exotic materials used are probably in the control computers.
  3. Some systems use readily-available proven turbo-machinery.
  4. Most systems appear to be scalable.
  5. All systems would appear to have a working life measured in decades.
  6. I would expect that most well-educated teenagers could understand how these systems worked.

Only Augwind Energy and Lumenion are new to me.

He finally sums up the economics and the market potential.

Our ability to expand energy storage capacity is one of the most pressing issues that will determine whether this defining ‘transitional’ decade is a success. But we’ll need to invest wisely into the right technologies that get the greatest bang for the buck (in terms of GWh capacity and return on capital) given the limited lifespan of Li-Ion and the decarbonisation of the grid.

At a current capital cost of US$2,000 per kW quoted by the US National Renewable Energy Laboratory (NREL) for 6-hour Li-ion battery storage, the 700GW of capacity needed by 2030 equates to around a US$1.5 trillion market over the coming decade, making it worth nearly US$200 billion a year.

The Energy Storage News article is a comprehensive must read for anyone, who is considering purchasing or investing in energy storage.

I have some further thoughts.

From My Experience Would I Add Any Other Systems?

I would add the following.

  • Form Energy, because its iron-air battery is well-backed financially.
  • Gravitricity, because it can use disused mine shafts to store energy and the world has lots of those.
  • STORE Consortium, because its 3D-printed concrete hemispheres, that store energy using pressurised sea-water can be placed within a wind farm.

I also suspect that someone will come up with an energy storage system based on tidal range.


When we started Metier Management Systems, finance to breakout from the first initial sales was a problem. We solved the problem with good financial planning and an innovative bank manager who believed us all the way.

David, was a rogue, but he was a rogue on the side of the angels. Long after Metier, he even came to my fiftieth birthday party.

David would have found a way to fund any of these systems, as they tick all the boxes of demonstrated, environmentally-friendly, safe and understandable. They are also likely to be bought by companies, governments and organisations with a high net value, a very respectable reputation and/or large amounts of money.

I also think, that just as we did with the original Artemis project management system, some of these systems can be leased to the operators.

Second-Use Of Systems

Several of these systems could be moved on to a new location, if say they were supporting an industry that failed.

That would surely help the financing of systems.
