Equinor And SSE Eye Green Hydrogen Production For 1.32 GW Dogger Bank D
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
SSE Renewables and Equinor, the developers of the Dogger Bank Wind Farm in the UK, are exploring two options for Dogger Bank D, the fourth wind farm the partners are looking to build as part of the development. These include using Dogger Bank D for electricity that would feed into the UK grid and/or for green hydrogen production.
This says to me, that depending on need, electricity from the Dogger Bank Wind Farms and D in particular, can be distributed in the grid or converted into green hydrogen.
- The article says that the electrolyser could become the UK’s largest green hydrogen project
- There will be plenty of hydrogen storage in the salt caverns at Aldbrough, which can currently store the equivalent of 320 GWh of electricity, It is currently being expanded to be one of the largest hydrogen stores in the world according to this page on the SSE web site.
- There are currently two gas-fired power stations at Keadby and they will in a few years be joined by a third, that will be fitted with carbon-capture and a hydrogen-fueled power station.
The various wind farms, power stations and gas storage on Humberside are growing into a very large zero-carbon power cluster, with an output approaching six GW.
Any shortfall in wind output, could be made-up by using the Keadby 3 gas-fired power station with carbon capture or the Keadby hydrogen power station.
Conclusion
Humberside is getting a cluster of power stations and wind farms, that can produce almost twice the electricity of Hinckley Point C nuclear power station.
Kittiwake Compensation
The title of this post, is the same as that of this page of Ørsted’s Hornsea Three web site.
The first section of the page gives the background.
Hornsea 3 Offshore Wind Farm received planning permission in December 2020. As part of our Development Consent Order, a requirement was included for ecological compensation measures for a vulnerable seabird species whose populations could be affected by wind farms – the Black-legged kittiwake (Rissa tridactyla).
Our compensation plan focusses on providing artificial nesting structures for kittiwake along the east coast of England. This project is the first of its kind and we are working on new and innovative designs for the artificial nesting structures. Each structure will be purpose-built, bespoke and specific to the landscape characteristics of each location. The structures also present an educational opportunity, allowing researchers to better understand kittiwake.
Developing effective environmental compensation measures is essential to ensure the UK Government’s targets for offshore wind can be realised, to deliver a net zero-carbon future.
So kittiwakes are not being paid compensation, as I don’t suspect many have bank accounts.
But they are being built a few new nesting structures.
Wikipedia has an entry on kittiwakes.
It notes that all European kittiwakes are of the black-legged variety and this is a picture, I took of some on the Baltic in Newcastle.
I’ve seen several pictures of kittiwakes lined up like these.
The document goes on to describe the work being done for the kittiwakes and this is said about work in East Suffolk.
Lowestoft and Sizewell are the only locations between Kent and Humberside with thriving kittiwake colonies. Kittiwake normally nest on steep cliffs with narrow ledges. East Anglia doesn’t have these natural nesting spaces, so kittiwake have reverted to colonising urban areas, for example on windowsills and ledges of buildings. Kittiwake breeding for the first time are most likely to find artificial structures that are situated close to these urban areas. They are less likely to find structures in places where there are not already kittiwake. Lowestoft and Sizewell are therefore two of the few places in East Anglia where artificial structures could be colonised quickly. These purpose-built nesting sites would improve breeding conditions for kittiwake, whilst successfully achieving our compensation requirements to unlock the world’s biggest offshore wind farm.
I took this picture of kittiwakes at Sizewell.
It doesn’t seem too unlike the structure on the Hornsea 3 web site.
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.
- The D-Floaters do look strong and sturdy.
- There are several competing floats for wind turbines based on triangles.
- 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.
MPS Floating Platform To Feature FibreMax Tendons
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Welsh company Marine Power Systems (MPS) has joined forces with FibreMax to provide integrated floating foundation and tendon solutions to the growing floating offshore wind sector.
And these three paragraphs outline the design.
The tendon solution will be used in the anchoring and moorings of MPS’ tension leg platform (TLP), called PelaFlex, to deliver the highest system stability and zero tilt, the partners said.
It will be the “world’s first” TLP with FibreMax tendons, made with Twaron fiber from Japan-headquartered Teijin.
Compared to traditional steel moorings synthetic cable offers a much better strength-to-weight ratio, longer operational life, and lower levels of maintenance, according to the partners.
Note.
- PelaFlex tension leg platforms are used in the project I wrote about in Simply Blue Group And Marine Power Systems To Pursue INTOG Innovation Project Opportunity.
- Wikipedia is a good source of information on tension leg platforms, where there is a large section on how they could be used for wind turbines.
- Twaron has an informative product page.
- There is more about PelaFlex on the PelaFlex web page including a video.
- The press release for the joint Simply Blue/MPS project talks of six turbines totalling up to 100 MW, which is probably around 17 MW per wind turbine.
It looks to me, that the PelaFlex design is getting better by the simple process of adding lightness and therefore being able to have a higher energy density in a deep area of the sea.
The amount of innovation involved probably makes PelaFlex an ideal component for the upcoming INTOG leasing round.
World’s First Semi-Submersible Floating Offshore Wind Farm Exceeds Expectations
The title of this post, is the same as that of this article on offshoreWIND.biz.
The article is based on this news item from WindFloat Atlantic, which is entitled WindFloat Atlantic Closes 2022, Reaching 78GWh.
These are the first three paragraphs of the news item.
WindFloat Atlantic, world’s first semi-submersible floating offshore wind farm, that was connected to the grid by the end of 2019 and commissioned in 2020, now finishes its full second year in operation.
After nearly 2 years and a half in fully operation, WindFloat Atlantic closes 2022 with an electricity production of 78GWh (+5% more than its first year). This production enables the supply of green energy to more than 25,000 households, as well as the avoidance of 33,000 tones of CO2.
These favourable data show Portugal’s potential on offshore wind energy, which is reflected in the annual availability of the wind farm, which was between 93-94%, as well as showing the success of WindFloat Atlantic’s innovative technology, being a benchmark within the offshore sector.
These points are from the news item.
- The wind farm is only 25 MW. So it is only a small wind farm.
- There were no lost time accidents in the last year of operation.
- It produced more electricity in 2022 than 2021.
- I have calculated the capacity factor at 36 %.
It certainly looks to be a successful application of floating wind power.
Germany Pinpoints 36.5 GW Of Offshore Wind Areas, Publishes Development Plan
The title of this post is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Germany’s Federal Maritime and Hydrographic Agency (BSH) has published a new area development plan for the expansion of offshore wind energy. The plan maps out the build-out of offshore wind by 2030, by when the country is to reach 30 GW of capacity connected to its grid, and sets the stage for further deployment of wind turbines at sea, with the 2035 target of 40 GW estimated to be exceeded.
30 GW of offshore wind by 2030 and 40 GW by 2035 are ambitious targets, but how do we compare?
This news story on the UK Government web site is entitled UK Signs Agreement On Offshore Renewable Energy Cooperation, contains this statement.
The initiative is expected to support the UK’s ambitious targets to increase offshore wind fivefold to 50GW, and deliver 18GW of electricity interconnector capacity – up from 8.4 GW today – by 2030.
I don’t think we compare badly.
UK Round 4 Offshore Wind Winners To Start Paying Option Fees With Lease Agreements Now Signed
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
The Crown Estate has signed Agreements for Lease for all six offshore wind projects selected in the UK’s Round 4 offshore wind seabed leasing. This enables the developers to now further progress their plans and also kicks off the period in which they will be paying annual option fees of almost GBP 900 million to The Crown Estate and HM Treasury.
The article then lists the wind farms.
- RWE’s Dogger Bank South East & West (3 GW).
- EnBW and BP’s Morgan and Mona (3 GW).
- TotalEnergies and Corio Generation’s Outer Dowsing (1.5 GW).
- Cobra and Flotation Energy’s Morecambe (480 MW).
This is just under 8 GW.
The article then goes on to show what developers will pay to the Crown Estate.
These two paragraphs explain the fees paid.
By signing the Agreements for Lease, which can be in effect for a maximum of ten years, the developers have committed to at least three years of option payments and will pay an annual option fee for each project until they are ready to enter into a lease for the seabed site.
The option payments, totalling some GBP 979 million per year, reduce as a project moves into a lease, or leases, and cease when a lease(s) for the maximum capacity/whole site is granted, at which point developers will move to paying rent.
It looks to me that developers will pay nearly a billion pounds per year for at least a minimum of three years and not more than ten years.
Once a project moves into a lease, rent will be paid.
It seems to be a very profitable occupation to own loads of empty sea!
Nucor Introduces Elcyon(TM), First Sustainable Steel Product Engineered Specifically For Offshore Wind Energy Applications
The title of this post, is the same as that of this press release from Nucor Corporation.
This is the first paragraph.
Nucor today introduced Elcyon™, the Company’s new sustainable heavy gauge steel plate product made specifically to meet the growing demands of America’s offshore wind energy producers building the green economy and its necessary infrastructure. Nucor will manufacture Elcyon at the company’s new, $1.7 billion state-of-the-art Nucor Brandenburg steel mill in Kentucky , which produced its first steel plate at the end of December 2022.
It sounds impressive, but it should be if $1.7 billion has been spent.
This paragraph, says more about the process.
Elcyon is a clean, advanced steel product made using Nucor’s recycled scrap-based electric arc furnace manufacturing process. Nucor’s circular steelmaking route has a greenhouse gas emissions intensity that is one fifth the global blast furnace extractive steelmaking average, based on Scope 1 and 2 emissions. Utilizing Thermo-Mechanical Controlled Processing (TMCP) at the new mill, Elcyon, the only steel of its kind in the United States was created specifically to meet the rigorous quality standards of offshore wind energy designers, manufacturers and fabricators. Along with meeting Euronorm specs, Elcyon is characterized by larger plate dimensions, improved weldability and excellent fracture toughness, as compared to competing products.
What more can a steelmaker want?
- It uses steel scrap to make new steel.
- The process could be powered by green electricity.
- The process cuts emissions to twenty per cent.
- The steel is what customers want.
- The steel has better properties than competing products.
These two paragraphs talk about the prospects for Elcyon.
Nucor Steel Brandenburg is the first steel plant in the world to pursue certification under LEED v4 from the U.S. Green Building Council, the highest standard for sustainable building design, construction, and operation. The new mill is located in the middle of the largest steel plate-consuming region in the country and will be able to produce 97% of plate products consumed domestically, with a potential output of 1.2 million tons of steel annually.
Elcyon and the Brandenburg mill both draw upon Nucor’s 50 years of industry leadership in sustainable steel production. From last year’s launch of Econiq™, the world’s first net-zero steel available at scale, to recently becoming the first major industrial company to join the United Nations 24/7 Carbon-Free Energy Global Compact, Nucor has consistently worked to meet the needs of its customers and other stakeholders while protecting the well-being of our planet.
Nucor have certainly done their market research and appear to be very scientifically green.
In the About Nucor section of the press release, this is the last sentence.
Nucor is North America’s largest recycler.
This is some statement to make, if it weren’t true! Wikipedia says this about the company.
Nucor operates 23 scrap-based steel production mills. In 2019, the company produced and sold approximately 18.6 million tons of steel and recycled 17.8 million tons of scrap.
The home page of the Nucor web site also makes this claim.
North America’s Most Sustainable Steel And Steel Products Company
Perhaps, the UK government needs to ask Nucor to build one or more of their scrap-based steel production mills in the country to produce all the steel plate we will need for our growing offshore wind industry.
We certainly have the GW to power the arc furnaces.
Conclusion
Nucor is a big beast to watch!
European Company To Make All Wind Turbine Blades 100 % Recyclable, Plans To Build Six Recycling Factories
The title of this post, is the same as that, of this article on offshoreWIND.biz.
This sub-heading outlines what the company plans to do.
A Denmark-based company Continuum plans to make all wind turbine blades fully recyclable and stop landfilling and their emissions-intensive processing into cement with six industrial-scale recycling factories across Europe, backed by investment from the Danish venture capital firm Climentum Capital and a grant from the UK’s Offshore Wind Growth Partnership (OWGP).
Other points in the article include.
- Continuum plan six factories.
- The first factory will open at Esbjerg in Denmark in 2024 and will be able to accept end-of-life blades this year.
- The second factory will be in the UK and it will be followed by others in France, Germany, Spain, and Turkey.
- Each factory will have the capacity to recycle a minimum of 36,000 tonnes of end-of-life turbine blades per year.
This paragraph describes, what will happen to the recycled turbine blades.
The company will recycle wind turbine blades into composite panels for the construction industry and the manufacture of day-to-day products such as facades, industrial doors, and kitchen countertops.
Looking at their description of their mechanical separation process, I suspect that they could recycle other products and manufacture lots of others.
Wind Generation Sets New Record In UK Surpassing 21 GW
The eye-catching title of this post, is the same as that of this article on Renewables Now.
I regard anything over 20 GW as very good, as the UK’s average daily consumption is typically around 23 GW, so surely we can find a couple of gigawatts of biomass, gas, hydro or nuclear.
The Renewables Now article says this about UK electricity generation.
According to National Grid ESO, on Monday, January 9, wind accounted for 50.2% of British electricity, nuclear for 15.9%, gas for 13.1%, imports for 10%, biomass for 4.8%, hydro for 3.8%, solar for 1.3% and coal for 1.1%. Tuesday’s wind record may undergo slight adjustments in expectation of all data for yesterday.
I shall be following these figures.
- Especially, as Wikipedia says another 3 GW will be installed this year.
But it does seem that we’re getting there with renewable electricity.
A Thought On Energy Storage
I also think that if we are generating large amounts of electricity at times, which are more than we need, then we had better crack on and build lots of energy storage.
If we don’t need the energy and Europe or Ireland doesn’t want it, then we must store it, so that if the wind isn’t blowing we can recover it for a useful purpose, even if it is only selling it to the Germans to make hydrogen, which is used to replenish their stores.
