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.

Small Nuclear Power Plants To Replace Gas In Quest For Net Zero

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

I was very much involved in the writing of project management software in the last three decades of the last century and if there’s one thing we’re generally good at in the UK, it’s complex project management.

Usually problems arise because of political or ignorant senior management meddling.

Our Energy Saviours

I believe our two energy saviours will be floating offshore wind and small nuclear reactors (SMRs) and both need good project management to be built successfully on production lines.

So I don’t see any reason, why we can’t build large numbers of floating offshore wind farms to supply our electricity.

They are also complimentary, in that the fleet of SMRs back up the wind.

Floating Wind First

Floating wind is likely to be developed at scale first, as certifying anything involving nuclear will take an inordinate time.

The electricity from floating wind farms will keep us going, but it is also starting to develop a nice line in exports.

This press release from Drax is entitled Britain Sending Europe Power Lifeline – Report, where this is the sub-title.

For the first time in over a decade, Britain became a net exporter of electricity to its European neighbours, making around £1.5bn for the economy in three months.

Note.

  1. The report was written by Imperial College.
  2. Two new interconnectors; Viking Link and NeuConnect between the UK and Europe are under construction.
  3. Several large wind farms are under construction and will be commissioned in 2023/24 and could add over 4 GW to UK electricity production.

Exports will only get better.

A Sprint For Wind

So we must have a sprint for wind, which will then provide the cash flow to allow the SMRs to roll in.

Or will that be too much for the ultra-greens, who would object to cash-flow from GWs of wind being used to fund SMRs?

The Celtic Cluster Launches New Regional Strategy To Maximise Offshore Wind Benefits

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

This is the sub-heading.

The Celtic Sea Cluster has released a new Regional Strategy that outlines how Wales and South West England can maximise floating offshore wind technology benefits, in line with the forthcoming Celtic Sea leasing process being delivered by the Crown Estate.

Who comprise the Celtic Cluster? This paragraph gives the answer.

According to the Cluster, which is led by its founding partners, the Welsh Government, Cornwall, Isles of Scilly Local Enterprise Partnership, Celtic Sea Power, Marine Energy Wales, and the Offshore Renewable Energy Catapult, the strategy will allow the region’s stakeholders to ensure their activities are aligned and can achieve their common objectives.

I am surprised the Irish aren’t involved politically.

  • The Irish Republic has a coastline on the Celtic Sea.
  • There are a lot of Irish companies, finance and engineers involved in wind farm development.

But the cluster does have a firm ambition, according to the article.

The Cluster’s ambition is to establish the Celtic Sea region as a world leader in floating offshore wind by 2030 and to deliver 4 GW of floating wind in the Celtic Sea by 2035, with the potential to grow to 20 GW by 2045.

Note.

  1. The Wikipedia entry for the Celtic Sea, gives the sea an area of 300,000 km2.
  2. 20 GW or 20,000 MW is to be installed by 2045.

That is an energy density of just 0.067 MW/km2.

In ScotWind Offshore Wind Leasing Delivers Major Boost To Scotland’s Net Zero Aspirations, I calculated that ten floating wind farms had an average energy density of about 3.5 MW per km².

I wouldn’t bet against a few more floating wind turbines being squeezed into the Celtic Sea.

100 MW Scottish Floating Wind Project To Deliver Lifetime Expenditure Of GBP 419 Million

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

This is the sub heading, that gives more details on lifetime expenditure and full-time equivalent (FTE) jobs created.

The 100 MW Pentland Floating Offshore Wind Farm in Scotland is estimated to deliver lifetime expenditure of GBP 419 million in the UK and to support the creation of up to 1,385 full-time equivalent (FTE) jobs.

It does seem these figures have been compiled using the rules that will apply to all ScotWind leases and have used methods laid down by Crown Estate Scotland. So they should be representative!

Does it mean that a 1 GW floating wind farm would have a lifetime expenditure of £4.19 billion and create 13, 850 full-time equivalent (FTE) jobs?

This article from Reuters is entitled UK Grid Reforms Critical To Hitting Offshore Wind Targets and contains this paragraph.

The government aims to increase offshore wind capacity from 11 GW in 2021 to 50 GW by 2030, requiring huge investment in onshore and offshore infrastructure in England, Wales and Scotland.

If I assume that of the extra 39 GW, half has fixed foundations and half will float, that means that there will be 19.5 GW of new floating wind.

Will that mean £81.7 billion of lifetime expenditure and 270,075 full-time equivalent (FTE) jobs?

Conclusion

It does seem to me, that building floating offshore wind farms is a good way to bring in investment and create full time jobs.

Hywind Tampen

In Equinor Sets Sights On Gigawatt-Scale Floating Offshore Wind Projects In Celtic Sea, I said this about Hywind Tampen.

Equinor is also currently constructing the 88 MW Hywind Tampen project in Norway, which will be the largest floating offshore wind farm in the world when completed in 2023.

This page on the Equinor web site gives more details of Hywind Tampen.

  • Hywind Tampen is a floating wind farm under construction that will provide electricity for the Snorre and Gullfaks oil and gas fields in the Norwegian North Sea.
  • It will be the world’s first renewable power for offshore oil and gas.
  • With a system capacity of 88 MW it will also be the world’s largest floating offshore wind farm.
  • The wind farm will consist of eleven 8 MW turbines.

When Hywind Tampen is operational, Equinor will operate nearly half (47 percent) of the world’s floating wind capacity.

This paragraph from the Equinor web page is significant.

The wind farm is estimated to meet about 35% of the annual electricity power demand of the five Snorre A and B, and Gullfaks A, B and C platforms. In periods of higher wind speed this percentage will be significantly higher.

I take this to mean that the gas turbines that currently supply the five platforms will be left in place and that their output will be replaced by wind power, when it is available.

The INTOG Program

I described this in What Is INTOG?, and it is the UK’s program, that includes electrification of rigs and platforms.

The first leases under INTOG would appear to be expected in March 2023.

Decarbonisation Of Offshore Operations Around The World

I’m sure that if Hywind Tampen and/or INTOG is successful, that the technology will be used where possible around the world.

Equinor Sets Sights On Gigawatt-Scale Floating Offshore Wind Projects In Celtic Sea

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

This is the opening paragraph of the article.

Equinor has disclosed its interest in developing gigawatt-scale floating offshore wind in the Celtic Sea, with the upcoming Celtic Sea floating wind seabed leasing round in view.

These are some other points from the article.

  • The Crown Estate is planning a seabed leasing round in the Celtic Sea in 2023.
  • As the developer and soon-to-be operator of two of the world’s first floating offshore wind farms, Equinor said it views new floating opportunities in the Celtic Sea with great interest.
  • Project development areas are being prepared by The Crown Estate for the development of gigawatt-scale floating offshore wind projects.

Equinor could move into the Celtic Sea in a big way.

On the Projects page of the Blue Gem website, this is said about floating wind in the Celtic Sea.

Floating wind is set to become a key technology in the fight against climate change with over 80% of the worlds wind resource in water deeper than 60 metres. Independent studies have suggested there could be as much as 50GW of electricity capacity available in the Celtic Sea waters of the UK and Ireland. This renewable energy resource could play a key role in the UK meeting the 2050 Net-Zero target required to mitigate climate change. Floating wind will provide new low carbon supply chain opportunities, support coastal communities and create long-term benefits for the region.

How much of this possible 50 GW of offshore wind in the Celtic Sea will be leased by the Crown Estate in 2023?

Odfjell Oceanwind and Source Galileo Norge Forge Floating Offshore Wind Alliance

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

The first highlighted paragraph outlines the possible deal.

Odfjell Oceanwind and renewable energy developer Source Galileo’s Norwegian branch, Source Galileo Norge, have signed a memorandum of understanding (MoU) to cooperate on developing floating offshore wind farms using Odfjell Oceanwind’s technology.

Note.

  1. Odfjell is a Norwegian shipping company, with this web site.
  2. Odfjell Oceanwind has a web site, with a mission statement of We are shaping the future of floating offshore wind power.
  3. Source Galileo style themselves as a Developer of Large-Scale Renewable Projects on their web site.

These three paragraph outline the cooperation’s plans.

  1. The cooperation will target wind farms for the electrification of oil and gas installations, the Utsira Nord seabed development, and selected floating wind parks in Europe.
  2. According to the partners, they also plan to apply for a seabed lease on Utsira Nord where the project, named UtsiraVIND, will use Odfjell Oceanwind’s proprietary solutions for cost-competitive, industrial production of floating offshore wind units.
  3. Odfjell Oceanwind is developing the Deepsea Semi floating wind foundation design which could be used in floating wind farms and for off-grid applications including temporary electrification of oil and gas installations in harsh environments.

They seem to have large ambitions, but then the money is available to fulfil the ones that work in Norway.

This Google Map shows area of Norway, that includes Utsira, Haugesund and Stavanger.

Note.

  1. Utsira is the largest island at the West of the map.
  2. Haugesund is on the coast to the North-East of Utsira.
  3. Stavanger is the fourth largest city in Norway and is at the bottom of the map.

There would appear to be plenty of space to place floating wind turbines between all the islands and the coast.

These are some other points from the article.

  • Odfjell Oceanwind floats appear to be able to handle 15 MW turbines.
  • In May, Norway initiated an investment plan to reach 30 GW of offshore capacity by 2040.
  • Work has started to prepare Norway for floating offshore wind.
  • Norway’s next offshore wind auction is in 2025.

Norway’s going large for wind!

Shannon Estuary Could Support Build-Out of 30 GW Of Floating Wind, House 2 GW of Electrolysis Capacity

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

This is the opening paragraph.

The Shannon Estuary in Ireland can support the build-out of up to 1.8 GW of floating wind per year and up to 30 GW by 2050. In addition, it could accommodate a 2 GW electrolyser for hydrogen and downstream e-fuels production, according to the US-headquartered company Bechtel, which reviewed the Shannon Foynes Port Company’s Vision 2041 masterplan.

The island of Ireland will truly be going green.

The Turbine Production Figures

The headline talks about rolling out 1800 MW of floating wind turbines per year and in the body of the article it says this.

At peak, up to 120 floating turbines could be installed offshore per year.

This would imply 15 MW turbines, which is entirely feasible.

As all these figures were produced and/or fully checked by Bechtel, I would suspect that they are very sound.

So does this imply that 120 floating wind turbines is a typical production limit of this type of turbine assembled in a custom-built facility in a port?
