30 MW Offshore Wind Turbines Being Considered For New Project In Sweden

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

This is the sub-heading.

Freja Offshore, a joint venture between Hexicon and Mainstream Renewable Power, has submitted an application for an offshore wind farm in Sweden that could have an installed capacity of between 2 GW and 2.5 GW and, according to the project’s consultation document, could feature wind turbines of up to 30 MW per unit.

This paragraph, indicates how turbines have grown over the last two decades.

The wind turbines in the future will probably be taller, the rotor diameter larger and the turbines more powerful, the joint venture says in the consultation document, and compares the largest wind turbines launched in 2011, which have a rotor diameter of 164 metres and an installed capacity of 8 MW, with those launched 10 years later, featuring a rotor diameter of 236 metres and an output of 15 MW.

Moving on a few years to 2030 and it doesn’t seem unreasonable that turbine size will double again to 30 MW.

I could see them becoming the standard turbine, providing they aren’t too heavy for the fixed foundations or floats.

It would be an interesting exercise to model the costs of wind farms, as the turbines get bigger.

With North Sea oil and gas, I was told several times, by Artemis users, that as cranes got larger, which allowed bigger lifts, the costs of offshore infrastructure decreased.

British Five-Year-Olds Up To 7cm Shorter Than Western Peers

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

This is the sub-heading.

Poor diet and health service cuts blamed for ‘pretty startling’ trend

These are the first two paragraphs.

Five-year-olds in Britain are on average up to seven centimetres shorter than their peers in other wealthy nations, in a trend described as “pretty startling”.

A poor national diet has been highlighted as a major culprit in Britain’s fall down international rankings of child height.

I am coeliac and am only 170 cm.

During the pandemic, I did some statistical research on coeliac disease and the covids for my own interest.

I found a peer-reviewed Indian medical paper entitled Coeliac Disease: Can We Avert The Impending Epidemic In India? The author felt that modern high-gluten wheats, were increasing the rate of the disease.

The author also said this about introduction gluten to babies in Sweden.

The time of first exposure to wheat influences the development of celiac disease. In countries such as Finland, Estonia, and Denmark, characterized by low gluten consumption in infancy, celiac disease prevalence is much lower than in Sweden where gluten consumption is high in infancy. A natural experiment occurred in Sweden about two decades ago when national recommendations were made to introduce wheat into the diet after cessation of breast feeding at six months. This change was coupled with increased wheat gluten consumption through infant feeds. Together these measures resulted in a two-fold increase in incidence of celiac disease in Sweden, which was attributed to introduction of wheat into the diet after cessation of breast feeding. In 1996 this recommendation was changed to introduce gluten in gradually increasing amounts while the infant was still being breast fed. This led to a dramatic decrease in celiac disease incidence.

It is interesting to look at heights of five-year-olds given in the Times article for the four countries.

  • Denmark – 117.4 – 118.1
  • Estonia – 116.9 – 115.7
  • Finland – 116.3 – 114.5
  • Sweden – 115.1 – 115.1

Note that all heights are in centimetres, with boys first.

As according to the graphs in the article the UK and the US have shown the biggest declines in height, is gluten-rich junk food, the major cause of this decline?

More research needs to be done!

UK Offshore Wind Pipeline Now At 98 GW, Second Only To China – Report

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

This is the sub-heading.

The UK’s pipeline of offshore wind projects has reached 97,944 MW, up from 91,287 MW a year ago, while the global pipeline topped 1.23 TWh, an increase of nearly 400 GW in the last year, according to RenewableUK’s latest EnergyPulse market intelligence data report.

 

These are the first two paragraphs.

The pipeline includes projects at every stage of development, including operational, under construction, consented, or planned.

The UK total pipeline was second globally at 98 GW, second only to China with 157 GW, followed by the USA in third place with 82 GW, Sweden is fourth with 75 MW, and Brazil fifth with 63 GW.

These is also a pie-chart saying in which part of the UK, wind energy is being developed.

  • North Sea (Scotland) – 41,977 MW
  • North Sea (England) – 33,845 MW
  • Irish Sea – 8,659 MW
  • North Atlantic Ocean – 7,435 MW
  • Celtic Sea – 4,428 MW
  • English Channel – 1,600 MW

As Cilla would say. “What a lorra, lorra lot of wind!”

Denmark And Germany Sign Bornholm Energy Island Agreement, First Legally Binding Cooperation On Joint Offshore Renewable Energy Project In EU

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

This is the sub-heading.

German Federal Minister for Economic Affairs and Climate Action, Robert Habeck, and Danish Minister for Climate, Energy and Utilities, Lars Aagaard, have signed an agreement for the Bornholm Energy Island in the Baltic Sea. This is the first legally binding cooperation agreement in Europe on a joint offshore energy project under the EU Renewable Energy Directive.

Bornholm is a Danish island between Denmark, Germany and Sweden, as this map shows.

Note.

  1. Malmo is in Sweden.
  2. Copenhagen is in Denmark.
  3. Germany is in the South-West corner of the map.

Bornholm is the island in the North-East corner of the map.

This paragraph gives the bare details of the generation and transmission capacities.

Bornholm Energy Island, located in the Danish sector of the Baltic Sea, will facilitate connecting at least 3 GW of offshore wind generation capacity to the grid by the early 2030s. The electricity will then be transported via new grid connections to Germany (2 GW ) and to the Danish mainland (1.2 GW).

The great advantage of an energy island, is that the electricity can be sent both ways according to where it is needed.

Some of the energy islands that have been proposed also include energy storage and/or hydrogen production.

This web site gives more details of the Bornholm Energy Island.

Under a heading of Why Build Energy Islands?, these reasons are given.

  • Environment and climate
  • Energy security in Europe
  • Inspiration for the world

Under a heading of What is an Energy Island?, this is said.

An energy island makes it possible to establish large wind farms at sea far from the coast. The energy produced by the wind turbines is sent via cables to the energy island, from where it is sent out to consumers. On Bornholm, a high-voltage facility must therefore be established on the island which can receive and distribute the electricity. After that, green power can be sent from Bornholm to millions of consumers in Denmark and Germany. Bornholm’s Regional Municipality is working hard to seize the energy island’s potential for job creation and local business growth, and in turning Bornholm into the green business beacon and transport hub for green fuels in the Baltic Sea.

I suppose it could be argued that in the UK, Orkney and Shetland are already energy islands and will become more so in years to come.

Energy islands, whether real or man paid certainly seems to be a concept that is growing in populatity, with several being developed.

ZeroAvia To Bring Zero-Emissions Flight To Sweden

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

These three paragraphs outline the deal.

ZeroAvia has announced this week that it has struck a deal to bring zero-emissions flights to Sweden.

Such a deal has been struck to allow commercial routes from Skellefteå Airport using hydrogen-electric powertrains with Braathens Airlines.

Braathens Airlines operates a fleet of 14 ATR 72 aircraft, which will eventually have these powertrains utilized for flights across Sweden.

ZeroAvia are also targeting de Havilland Canada Dash 8 airliners for conversion to hydrogen.

Floating Offshore Substation Project Secures EUDP Funding

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

This is the sub-heading.

Semco Maritime, ISC Consulting Engineers, Aalborg University, Energy Cluster Denmark, and Norway and Sweden-based Inocean have secured funding to further develop a floating offshore substation (FOSS) concept.

This is the first paragraph.

The parties announced their collaboration in 2022 and are now set to further accelerate floating offshore substation development through funding from the Energy Technology and Demonstration Program (EUDP).

These three paragraphs talk about the design.

The substation layout has been developed to fit the shape of a three-column stabilised substructure, according to the partners.

The floating offshore substation is a crucial component in the offshore wind farm industry as deeper ocean sites further from the coastline are to be utilised, the partners said.

Between 60-80 per cent of the world’s offshore wind energy potential is in areas with depths greater than 60+ metres, which presents a need for an alternative solution to bring the power to shore, such as a floating offshore substation, according to the developers.

That all seems sensible.

Hydro-Storage Options To Be Studied For Grängesberg

The title of this post, is the same as that of this news item from Anglesey Mining.

These are the highlights of the news item.

  • Anglesey Mining plc, together with its 49.75% owned subsidiary Grängesberg Iron AB (“GIAB”) have entered into an MoU with Mine Storage to investigate the potential for the Grängesberg Mine to be converted into a Pumped Hydro-Storage project at the end of the mine’s producing life.
  • Pumped-Hydro Storage is a green-energy storage solution that utilises water and gravity to store electrical energy. An underground mine can provide a closed-loop solution using proven, pumped hydro-power technology. Essentially, the system involves water being gravity fed through pipes down a shaft into the turbines, which produce electricity for supply to the grid and also pump the water back to surface. The mine storage system has a high round-trip efficiency of 75-85% and proven durability.
  • The MoU with Mine Storage could lead to numerous future benefits.

I like this project.

Too often, when mines, quarries or other large operations come to the end of their economic lives, they are just abandoned in the hope that something worthwhile will happen.

But here we have a company planning the end of an iron ore mine in a way that will turn it into a source of future revenue.

I have a few thoughts.

Mine Storage

Mine Storage are a Swedish company with an informative web site.

The web site answered most of my questions.

Mines Are Moving From a Liability To A Resource

Consider.

  • Gravitricity are using mines to store energy using cables and weights.
  • Charlotte Adams and her team at Durham University are developing the use of the heat in abandoned coal mines.
  • The Global Centre of Rail Excellence is being developed in a disused opencast mine in Wales.
  • RheEnergise are developing their first High Density Hydro system in the Hemerdon Tungsten Mine in Devon.

And now we have this co-operation between Anglesey Mining and Mine Storage working together on pumped storage hydroelectricity.

Where is Grängesberg

This Google Map shows the location of Grängesberg.

It is convenient for storing energy for Stockholm.

The Luck Of The Genes

There’s an article in The Times, which is entitled When It Comes To Success, Luck Can Trump Intelligence.

It got me thinking about my life.

I have been pretty successful in life, and I put it down to winning the gene lottery, with a part-Jewish father and a part-Huguenot mother, who taught me hard work and everything they knew. So were my genes forged by religious persecution in the harsh conditions of the ghettoes of Europe?

But luck has always played a great part in my success. On the way, three or four successful men have chosen me for projects and I’ve repaid them by succeeding. I’ve been at the heart of the creation of two world-changing companies.

But the luck turned bad, a dozen years ago. My wife and our youngest son died from cancer and I had a serious stroke.

But the genetic lottery of being coeliac and therefore having B12 injections, has meant, I’ve made a good recovery from the stroke. The B12 injections is a stroke recovery method from the States, but is considered quackery over here. I believe it saved my life.

And then during the pandemic, those coeliac genes and the gluten-free diet I need for health, seem to have protected me from a severe dose of the covids. I’ve yet to find a fellow coeliac, who has had one either. Scientific research from Italy and Sweden, is also backing up my observations.

Lady luck has smiled on me. Or does the devil, look after her own?

An Elegant Solution

There’s an old English expression about couples lying in bed like spoons.

I wonder, if this analogy is used in other languages like Swedish.

Swedish company; Bassoe Technology have certainly used the stacking technique of spoons or bodies in the design of their innovative wind-turbine floats, which they call D-Floaters.

This visualisation shows five D-floaters being transported on a ship.

Note.

  1. The D-Floaters do look strong and sturdy.
  2. There are several competing floats for wind turbines based on triangles.
  3. There is probably an optimal cost between transporter ships and D-Floaters.

Given that these structures may be moved thousands of miles before installation, this method of transportation must be economic.

The loaded ship does remind me of one of the bath toys my kids had in the 1970s.

Another Renewable Power Idea From Sweden

I have posted some ideas from Sweden on this blog including.

And now there’s the SEATWIRL,  which the company says is the future of offshore wind.

In the Areas Of Use, there is a section with a heading of SeaTwirl For Niche Markets, where this is said.

SeaTwirl has now identified markets where wind turbines of the size of 1 MW can meet a clear market demand and sees a possibility to build a business aimed at these niche markets in parallel with its main target. That can mean revenues for the company sooner than was originally planned.

The niche markets that have been identified are islands and remote seaside villages, fish farms and desalination plants. These are business and places that today are run mainly on electricity from diesel generators, which is both expensive and emits CO2.

One of the places I would use these turbines, is on the apex of four-beam steel portal frame buildings. The original concept for these buildings had been developed at Cambridge University during World War Two and one of the team, had set up a business in Warwickshire, constructing these buildings for barns, factory units and other purposes.

He had programmed a simple computer program, which he ran on a time-shared computer system. I was hired to improve the computer program.

What surprised me was the strength of these buildings and I believe they could support vertical turbines like SeaTwirl along the apex.

I feel there are many other applications, especially if they are designed to be part pf a bigger system.

Conclusion

I like the concept of SeaTwirl.
