Norwegian Companies To Explore Using Aluminium In Floating Offshore Wind Turbines
This is based on this press release from World Wide Wind, which is entitled WORLD WIDE WIND AS and HYDRO ASA Signs Letter Of Intent Aiming At Using Aluminium In Offshore Floating Wind Turbines.
This is the first paragraph.
Hydro, the world leading Norwegian aluminium and energy company and World Wide Wind AS, a Norwegian company developing a floating wind turbine, have signed a Letter of Intent (LoI) to explore the use of aluminium in the renewable wind industry. The two Norwegian companies are partnering up to develop floating wind turbines with a design specifically meant for offshore conditions. The goal is to use sustainable and recyclable materials in the construction, including aluminium.
In Do All Wind Turbines Have To Be Similar?, I said this about the radically different turbines of World Wide Wind.
I’ll let the images on the World Wide Wind web site do the talking.
But who would have thought, that contrarotating wind turbines, set at an angle in the sea would work?
This is so unusual, it might just work very well.
As aluminium is lighter, it might be a factor in the success of the design.
This is the last paragraph of the press release.
World Wide Wind’s integrated floating wind turbines are scalable up to 40MW – 2,5 times current wind turbines – and will use less materials and have a smaller CO2 footprint than conventional turbines. It is World Wide Wind’s ambition that these turbines will represent future design for floating wind turbine design.
40 MW is a very large turbine. This is definitely a case of handsome is as handsome does!
Passenger Tunnel Linings At Waterloo Underground Station
This pictures show the cast-iron pedestrian tunnel linings at Waterloo tube station.
The Jubilee Line opened in 1999.
In the last few years, concrete has been able to be 3D-printed, so it can now be produced in different shapes.
All these wall and roof panels on the Elizabeth Line were made by 3D-printing of concrete.
Conclusion
Design has progressed in 25 years.
Concretene Cements Its Future With £8m Funding
The title of this post, is the same as that of this article in The Times.
This is a precis. which explains what Concretene have done.
Concretene combines graphene with concrete to form a “stronger, more sustainable and more cost-effective alternative” to the world’s most-used building material.
The eight million funding is mainly to be used for more tests.
Is Concrete The New Wonder Material?
I once lived in a concrete apartment and although it is now fifty years old, it still looks the same, as it did the day it was built.
Cromwell Tower
Cromwell Tower in The Barbican may have been built to a high specification, but we don’t hear cancer, cladding, damp, fire or mould problems about the City of London’s flagship housing estate.
In the last few years, concrete has been able to be 3D-printed, so it can now be produced in different shapes.
All these wall and roof panels on the Elizabeth Line were made by 3D-printing of concrete.
The technique also seems to be being used on High Speed Two.
These innovative uses of concrete have led to research into the manufacture and use of concrete.
These posts are must-reads.

The number of these posts show how much research is going into cutting the massive amount of carbon dioxide emitted by the concrete industry.
I also feel that some could work together.
Earth Friendly Concrete is a replacement for normal concrete, so perhaps it could be enhanced with graphene, to create an Earth Friendly Concretene.
Vattenfall Boosts Capacity For Norfolk Offshore Wind Zone
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Vattenfall is increasing the capacity for the Norfolk Offshore Wind Zone off the UK from 3.6 GW to over 4.2 GW, meaning that an additional 700,000 homes will be powered by the zone, the energy company said.
This is a sixteen percent increase in capacity.
In this article in the Eastern Daily Press, this is said.
Rob Anderson, project director of Vattenfall’s Norfolk Zones, said that the increase is due to the project using “innovative” technology and being “able to maximise its design”.
Moving from 12 MW to 14 MW turbines would give the planned increase.
This article on offshoreWIND.biz, is entitled Siemens Gamesa Ships Out First Set Of 115-Metre Wind Turbine Blades.
This is said about the two Norfolk Zone wind farms.
The SG 14-236 DD model will be commercially available in 2024 and has so far been selected as a preferred option for the Norfolk Vanguard and Boreas wind farms offshore the UK, as well as for the MFW Bałtyk II and MFW Bałtyk III wind farms in the Polish Baltic Sea.
It looks to me that Siemens Gamesa have got a success in the making.
It should be noted that the offshore floating wind farm named Ossian could increase from 2.6 GW to 3.6 GW, which I wrote about in Ossian Floating Wind Farm Could Have Capacity Of 3.6 GW.
A similar effect of size increases happened in North Sea Oil and Gas in the 1970s, as the cranes got larger and the techniques got better.
Is history repeating itself?
Offshore Wind Turbines Need To Be Standardised, Energy Transition Industrialised To Reach Targets, Says Siemens Energy VP For Western Europe
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Governments need to move from talking about policies to implementation, the offshore wind industry needs to employ standardisation, and clear rules and regulations need to be set for green hydrogen in order to move faster with large-scale deployment and achieve meaningful progress in limiting global warming to 1.5 degrees Celsius.
The guy has a point, as mass production of anything is generally more efficient and creates more units in a given time.
But can a diverse group of politicians, agree on a standard for turbines, fixed foundations, floaters, cables and sub-stations and then make sure all are identical and clip together like Lego? I doubt it!
And how would you fit innovative designs like TwinHub into a standard.
This image shows one of their TwinHub turbine installations being towed into place.
At least it could be built to hold two standard turbines.
Hyperbat In Multimillion-Pound Deal To Supply Battery Packs For Lotus Supercar
The title of this post, is the same as that of this article on The Times.
Lotus or supercars for that matter, will not be a big market for battery packs, but they will be a high-profile one. The article in The Times may well flush out a few good sales leads from companies who want to decarbonise their products.
Many years ago, I did a consultancy job for Cummins, where my software was used to look for faults in their engine testing system. One of their engineers explained to me that they had a sales and production philosophy that could handle all markets from the large down to small niche ones. He said that we can’t tell which niche markets are going to be successful.
In the last couple of years Cummins have embraced hydrogen very strongly and it looks like they are adopting a similar philosophy.
So in the Cummins engine business model, it looks like the niche market is important.
I suspect that what goes for the diesel engine market will also go for the electric transmission market, with niche markets being nicely profitable and an important part of sales.
It looks to me that Hyperbat are going for that market, backed up by the engineering and battery experience of Williams Advanced Engineering and the manufacturing knowledge and logistics of Unipart.
Note that Williams Advanced Engineering is now owned by Australian billionaire; Andrew Forrest, through his company; Fortescue Future Industries. I wrote about this purchase in Fortescue Buys Williams Engineering In Major Push Into High Performance Batteries.
On the Hyperbat web site, this is said about their manufacturing facility.
The facility is about to double in size to meet current needs, with plans to double again in the next 2 years.
The factory is based on the site of a former exhaust plant and reintroduces manufacturing to the area, with an environmentally sustainable future.
Capacity of the factory is approximately 10,000 packs per year.
I;m sure the company, has enough backing for a very successful future.
The Secret Of The TwinHub
I was reading about the TwinHub, which is a pair of wind turbines, that are to be mounted on a single float.
There is an explanatory video on the TwinHub home page. Just scroll the page down and you’ll find a full page video, that is rather beautiful and slightly hypnotic.
But note how it stops and starts in the wind and turns itself into a position, so that it is generating the maximum amount of wind.
So how does it do that?
It is not by clever computers and a whole host of actuators, but by good old-fashioned aerodynamics.
Above the video, there is a picture of the sea, with these words underneath.
This demonstration project will be located at the Wave Hub site, and will consist of two floating platforms anchored to the seabed. Each floating platform will host two turbines with inclined towers. The total installed capacity will be between 30 to 40 MW.
Two words are the key to the design – inclined towers.
The wind will apply a force to each turbine and because the towers are inclined, this will apply a force, that will turn the turbines so they are facing the wind. This will maximise the power generated.
The design is elegant, efficient and enchanting.
I can see the TwinHub becoming an unusual tourist attraction in Cornwall.
Passengers Of Reduced Mobility And The Elizabeth Line
I took these pictures at Whitechapel station and they show the preferred wheelchair entry point to the Class 345 train and the central car of the train, which has four wheelchair spaces.
Note.
- The well-signed wheelchair entrance to the train.
- Thw four wheelchair spaces are in the middle car of the train.
- There is no step into the train.
- The roundels also have directions to other lines and the way out.
The car also has longitudinal seating and lots of vertical grab rails.
I do find it strange that London is very much alone in the UK in using this seating design.
