Hysata – Electrolyser Breaks Efficiency Records, Enabling World-Beating Green Hydrogen Cost
The title of this post, is the same as that of this article on Hydrogen Central.
These three paragraphs explain what Hysata have achieved.
Hysata – electrolyser breaks efficiency records, enabling world-beating green hydrogen cost.
Hysata’s world-leading hydrogen electrolyser technology has been recognised on the global stage with ground-breaking research published in top tier peer-reviewed scientific journal Nature Communications.
The research confirms Hysata’s ‘capillary-fed electrolysis cell’ can produce green hydrogen from water at 98% cell energy efficiency, well above International Renewable Energy Agency’s (IRENA) 2050 target and significantly better than existing electrolyser technologies, enabling a hydrogen production cost well below A$2/kg (US$1.50/kg).
Note.
- Hysata are an Australian company.
- The research and its results have have met the gold standard of pier review in a respected journal.
Their efficiency levels would appear to be breathtaking.
I have some more information and a couple of thoughts.
The Technology
This article on New Atlas is entitled Record-Breaking Hydrogen Electrolyzer Claims 95% Efficiency, gives a full overview of the technology.
It does appear that Hysata have shown tremendous attention to detail to raise the efficiency.
The Efficiency
In Can The UK Have A Capacity To Create Five GW Of Green Hydrogen?, I said the following.
Ryze Hydrogen are building the Herne Bay electrolyser.
- It will consume 23 MW of solar and wind power.
- It will produce ten tonnes of hydrogen per day.
The electrolyser will consume 552 MWh to produce ten tonnes of hydrogen, so creating one tonne of hydrogen needs 55.2 MWh of electricity.
55.2 MWh/tonne is 55.2 kWh/kg.
Hysata are claiming on their web site, that their electrolysers have 95% efficiency, which is 41.5 kWh/kg.
- A megawatt of electricity at Herne Bay will produce 18.1 Kg of hydrogen.
- A megawatt of electricity in a Hysata electrolyser will produce 24.1 Kg of hydrogen.
That is 33 % more.
Conference Calls For More Freight Routes To And From Spain
The title of this post, is the same as that of this article on Railway Gazette.
This is the first paragraph.
Salvador Galve, Chairman of the Railway Commission of the General Council of Industrial Engineers, presented the European Alliance for the Development of Railway Corridors in the Iberian Peninsula initiative at a conference held in Madrid on March 9.
These are some points from the article.
- Less than 4% of freight is currently transported by rail in Spain, compared with an average of 18% across the EU.
- The Spanish government wants to raise this to 20%.
- Incidentally, in the UK, rail freight is at a level of 5 %.
- Italy has seven main lines connecting it to its neighbours, Spain has only two!
- Spain also has a break of gauge, whereas the UK and Italy do not!
- Plans exist for more freight corridors in Spain, and linking these to ports in North Africa and logistics hubs in the rest of Europe.
- Zaragoza, could be turned into a key southern European logistics hub, linked by tunnels to the main line between Toulouse and Bordeaux.
But to me the most interesting plan is set out in this paragraph.
On March 1 the Infrastructure Ministry gave its provisional approval for study into the feasibility of converting the single track, non-electrified line from Huesca to Canfranc from 1 668 mm gauge to 1 435 mm gauge, ahead of any possible reconstruction of the through route to Pau in France in the longer term.
It has always been on my bucket list to visit the magnificent Canfranc station.
UK On Track To Reach 4,000 Zero Emission Bus Pledge With £200 Million Boost
The title of this post, is the same as that of this press release from the Government.
These are the main points of the press release.
- Nearly 1,000 more zero-emission buses to be funded in towns and cities across the country, bringing the total funded in England to 2000 so far under this government.
- A further 600 zero-emission buses have been funded in Scotland, Wales and Northern Ireland.
- Comes as consultation launched on ending sale of all new non-zero emission buses from 2025 to 2032.
- Government continues taking unprecedented action to hit net zero and level up transport across the country.
Areas to get the new buses include.
- Blackpool
- Greater Manchester
- Hertfordshire
- Norfolk
- North Yorkshire
- Nottingham
- Oxfordshire
- Portsmouth
- South Yorkshire
- West Midlands
- West Yorkshire
- York
I would also like to see the government fund trials for the conversion of suitable buses to zero carbon. I certainly believe that London’s New Routemaster buses could be converted to hydrogen.
Sizewell C Nuclear Power Station: Government To Take 20% Stake
The title of this post, is the same as that of this article on the BBC.
This is the first three paragraphs.
The government plans to take a 20% stake in a £20bn large-scale nuclear plant at Sizewell, the BBC has learned.
French developer EDF will also take a 20% stake in the Suffolk power station.
Ministers hope the confirmation of two cornerstone investors will encourage infrastructure investors and pension funds to take up the remaining 60%.
I used to live near Sixewell and the general feeling of local Suffolk people is not particularly against having nuclear power stations in their back yards.
There are several small points in favour of Sizewell C.
- Sizewell has been operating nuclear power plants safely since the 1960s.
- Leiston, which is the nearest town, has a very strong engineering tradition.
- Leiston also improved by several notches during the building of Sizewell B.
- The site is accessible by rail and possibly sea with the right ship.
- Nuclear fuel can be brought in and out by train.
- If they spent a small amount on the train service to Saxmundham, construction workers could come in by train.
- Sizewell C has been proposed to be used to generate hydrogen for Freeport East at the Ports of Harwich an Felixstowe.
- The power cable to take electricity from Sizewell C towards London is already built.
- Sizewell is much more convenient to get to from London, than other possible nuclear sites.
Overall, I feel that Sizewell is a good place for nuclear power station.
On the other hand, there are these points against the station.
- There will be at least 6.7 GW of wind farms built off the East Anglian coast before Sizewell C is completed.
- There may be substantial objection to the new power station.
- Large nuclear power stations are rarely built to time and on budget.
- I feel that if we go the nuclear route, that small modular nuclear reactors may be better.
I can understand why Governments like Sizewell as a nuclear power station site.
ScotWind N3 Offshore Wind Farm
I introduced this wind farm in ScotWind Offshore Wind Leasing Delivers Major Boost To Scotland’s Net Zero Aspirations as Lease 15 – The Odd Bid Out.
I said this.
In any design competition, there is usually at least one design, that is not look like any of the others.
In the successful bids for the ScotWind leases, the bid from Magnora ASA stands out.
- The company has an unusual home page on its offshore wind web site.
- This page on their web site outlines their project.
- It will be technology agnostic, with 15MW turbines and a total capacity of 500MW
- It will use floating offshore wind with a concrete floater
- It is estimated, that it will have a capacity factor of 56 %.
- The water depth will be an astonishing 106-125m
- The construction and operation will use local facilities at Stornoway and Kishorn Ports.
- The floater will have local and Scottish content.
- The project will use UK operated vessels.
- Hydrogen is mentioned.
- Consent is planned for 2026, with construction starting in 2028 and completion in 2030.
This project could serve as a model for wind farms all round the world with a 500 MW power station, hydrogen production and local involvement and construction.
I have some thoughts.
The Location Of The Windfarm
This Google Map shows the area between Stornaway and Kishorn.
Note.
- The island in the North-West of the map is Lewis and Harris.
- The windfarm will be to the North-West of the island.
- Stornaway is on the isthmus, that connects the small peninsular on the East of the island.
- The port of Stornaway is on the South side of the isthmus.
- The port of Kishorn is shown by the red arrow.
This second Google Map shows the town of Stornaway.
Note that Stornaway has a substantial airport in the East and a large port.
This third Google Map shows Loch Kishorn in more detail.
Kishorn Yard at the Kishorn Port was originally built to create the large structures in steel and concrete for the development of North Sea Oil. This is an extract from the Wikipedia entry.
The yard was therefore well suited to build the 600,000-tonne concrete Ninian Central Platform, which was built in 1978. Material was supplied by sea and when complete the platform needed seven tugs to tow it to its operating position in the North Sea. The Ninian Central Platform still holds the record as the largest movable object ever created by man.
If the yard could build the Ninian Central Platform, I’m sure that Magnora ASA intend to build the concrete floater in Loch Kishorn.
The Floating Wind Turbines
In visualisations on the site, the floating wind turbines are shown as sitting on floating three-pointed star structures.
As Technip UK are partners in the project and I suspect they are a subsidiary of TechnipFMC, who are a well-known company described like this in Wikipedia.
TechnipFMC plc is a French-American, UK-domiciled global oil and gas company that provides complete project life cycle services for the energy industry.
The company would certainly have the expertise to design a floating platform for a wind farm.
Like the WindFloat, it could be based on semi-submersible offshore platform technology.
The Magnora web site, say that 15 MW wind turbines will be used, so these will probably be some of the largest wind turbines in the world.
Currently, the largest floating wind turbines are the 9.5 MW units at the Kincardine Wind Farm in Scotland.
33 x 15 MW wind turbines would give a capacity of 495 MW.
I suspect the turbines would be towed to Stornaway or Kishorn for major servicing.
What Will The Concrete Floater Do?
There are a variety of tasks that the concrete floater could handle.
- It could collect the electricity from the wind turbines. I suspect this would give advantages in the connection and disconnection of individual turbines into the windfarm.
- Any electricity conversion necessary would be handled on the floater.
- The floater would handle the seaward end of the connection to the shore.
- There could be a battery or energy storage device on the floater.
- Could a Gravitricity battery or something similar be built into the floater?
- Magnora mention hydrogen on their web site. Could an electrolyser be built on the floater and the hydrogen distributed to Lewis and Harris by pipeline?
Some oil and gas platforms are very comprehensive and there is no reason why there can’t be substantial processing done on the floater.
The Concrete Floater
According to Wikipedia, offshore concrete structures have been in use successfully for about 50 years. Nearly fifty are in use in the oil and gas industry.
Wikipedia introduces its section on floating concrete structures like this.
Since concrete is quite resistant to corrosion from salt water and keeps maintenance costs low, floating concrete structures have become increasingly attractive to the oil and gas industry in the last two decades.
I also wonder if a floating concrete structure would make a good hydrogen storage tank, if there is electrolysis on the floater on the to turn electricity into hydrogen.
Conclusion
My original conclusion after reading about this wind farm was.
This project could serve as a model for wind farms all round the world with a 500 MW power station, hydrogen production and local involvement and construction.
I have no reason to change my mind and feel that the concept may have even more possibilities.
ScotWind Offshore Wind Leasing Delivers Major Boost To Scotland’s Net Zero Aspirations
The title of this post, is the same as that of this press release on the Crown Estate Scotland web site.
This is the first two paragraphs.
Crown Estate Scotland has today announced the outcome of its application process for ScotWind Leasing, the first Scottish offshore wind leasing round in over a decade and the first ever since the management of offshore wind rights were devolved to Scotland.
The results coming just months after Glasgow hosted the global COP26 climate conference show the huge opportunity that Scotland has to transform its energy market and move towards a net zero economy.
Some highlights are then listed.
- 17 projects have been selected out of a total of 74 applications.
- A total of just under £700m will be paid by the successful applicants in option fees and passed to the Scottish Government for public spending.
- The area of seabed covered by the 17 projects is just over 7,000km2.
- Initial indications suggest a multi-billion pound supply chain investment in Scotland
- The potential power generated will move Scotland towards net-zero.
This map shows the position of each wind farm.
Note, that the numbers are Scotwind’s lease number in their documents.
Fixed Foundation Wind Farms
These are the six fixed foundation wind farms.
- 1 – BP Alternative Energy Investments – 859 km² – 2.9 GW
- 6 – DEME – 187 km² – 1.0 GW
- 9 – Ocean Winds – 429 km² – 1.0 GW
- 13 – Offshore Wind Power – 657 km² – 2.0 GW
- 16 – Northland Power – 161 km² – 0.8 GW
- 17 – Scottish Power Renewables – 754 km² – 2.0 GW
Adding up these fixed foundation wind farms gives a capacity of 9.7 GW in 3042 km² or about 3.2 MW per km².
Floating Wind Farms
These are the ten floating wind farms.
- 2- SSE Renewables – 859 km² – 2.6 GW
- 3 – Falck Renewables Wind – 280 km² – 1.2 GW
- 4 – Shell – 860 km² – 2.0 GW
- 5 – Vattenfall – 200 km² – 0.8 GW
- 7 – DEME Concessions Wind – 200 km² – 1.0 GW
- 8 – Falck Renewables Wind – 256 km² – 1.0 GW
- 10 – Falck Renewables Wind – 134 km² – 0.5 GW
- 11 – Scottish Power Renewables – 684 km² – 3.0 GW
- 12 – BayWa r.e. UK – 330 km² – 1.0 GW
- 14 – Northland Power – 390 km² – 1.5 GW
Adding up the floating wind farms gives a capacity of 14.6 GW in 4193 km² or about 3.5 MW per km².
Mixed Wind Farms
This is the single wind farm, that has mixed foundations.
15 – Magnora – 103 km² – 0.5 GW
This wind farm appears to be using floating wind turbines.
I have a few general thoughts.
Are Floating Wind Farms Further Out?
There does appear to be a pattern, where the wind farms that are further from the land tend to be floating wind farms and those closer to the land appear to be fixed.
Consider.
- As the water gets deeper, fixed wind turbines will surely get more expensive.
- Floating wind turbines are the newer and more unproven technology, so only those bidders, who have done their research and are happy with it, will have bid.
Falck Renewables Wind Seem To Be Working With BlueFloat Energy
In the three Falck Renewables successes with leases 3, 8 and 10, BlueFloat Energy is a partner in the lease.
According to their web site, BlueFloat Energy were very much involved in WindFloat Atlantic, where this is said.
Top members of our team were key contributors to the development and construction of the WindFloat Atlantic project from concept to Final Investment Decision to commissioning. This 25 megawatt (MW) floating offshore wind project in Portugal marked a turning point in the offshore wind industry as it was the first floating offshore wind project to secure bank financing. With 3 x MVOW’s 8.4 MW turbines, the WindFloat Atlantic project was the world’s first semi-submersible floating wind project and continental Europe’s first floating wind project.
So do Falck Renewables intend to use WindFloat technology in their areas, which are to produce a total of 2.7 GW?
Perhaps a fleet of two hundred floating wind turbines based on WindFloat technology each with a capacity of 14 MW would be ideal.
- Wind turbines would be interchangeable between all three farms.
- There could be a few standby turbines to allow for maintenance.
- It would be possible to borrow a turbine to explore a new site.
All it would need is technology to be able to position and connect a turbine into the wind farm and disconnect and remove a turbine from the wind farm, with simple procedures.
Did BP Avoid the Floating Wind Farms?
BP, who are relatively new to offshore wind, only had one success, for a large fixed wind farm. So did they avoid the floating wind farms?
Do Shell and Scottish Power Have A Bigger Plan?
Shell and Scottish Power were successful with leases 4 and 11, which are reasonably close together.
They also won lease 17, which I wrote about in MacHairWind Wind Farm, where I concluded this.
The MacHairWind wind farm seems a well-positioned wind farm.
- It is close to Glasgow.
- It can be used in tandem with the Cruachan pumped hydro power station.
- It will have access to the Western HVDC Link to send power to the North-West of England.
Is Scotland replacing the 1.2 GW Hunterston B nuclear power station with a 2 GW wind farm, with help from Cruachan and other proposed pumped storage hydro schemes to the North of Glasgow?
So did Shell and Scottish Power get the pick of the bunch and will build two large floating wind farms close together?
Shell and Scottish Power seem to be using French company; Eolfi’s floating wind technology.
Why Do Floating Wind Farms Have A Higher Density?
The floating wind farms have an average energy density of 3.5 MW per sq. km, whereas the fixed wind farms only manage 3.2 MW per sq. km.
It may be only ten percent, but does that help the economics? It certainly, wouldn’t make them worse.
I do wonder though, if the reason for the higher density is simply that a floating turbine can be bigger, than a corresponding fixed turbine.
I also have a few more specific thoughts about individual farms.
Lease 15 – The Odd Bid Out
In any design competition, there is usually at least one design, that is not look like any of the others.
In the successful bids for the ScotWind leases, the bid from Magnora ASA stands out.
- The company has an unusual home page on its offshore wind web site.
- This page on their web site outlines their project.
- It will be technology agnostic, with 15MW turbines and a total capacity of 500MW
- It will use floating offshore wind with a concrete floater
- It is estimated, that it will have a capacity factor of 56 %.
- The water depth will be an astonishing 106-125m
- The construction and operation will use local facilities at Stornoway and Kishorn Ports.
- The floater will have local and Scottish content.
- The project will use UK operated vessels.
- Hydrogen is mentioned.
- Consent is planned for 2026, with construction starting in 2028 and completion in 2030.
This project could serve as a model for wind farms all round the world with a 500 MW power station, hydrogen production and local involvement and construction.
I discuss this project in more detail in ScotWind N3 Offshore Wind Farm.
A Conclusion About Floating Wind
The various successful bids in this round of Scottish wind farm leases can be split by capacity into two groups.
- Floating + Mixed – 15.1 GW – 61 %
- Fixed – 9.7 GW – 39 %
Note that I have included Magnora’s successful mixed bid with the successful floating bids, as it uses floating wind turbines to generate electricity.
The over 60 % of successful bids involving floating wind farms, indicates to me, that the day of floating wind farms has arrived.
Hydrogen Fuel Cell Trucks And H2 Infrastructure Could Benefit From New Legislation
The title of this post, is the same as that of this article on Hydrogen Fuel News.
Politicians from both main parties in the United States are promoting a Hydrogen for Trucks Act, to support the conversion of domestic trucking from diesel to hydrogen.
These are the three main parts of the Act
- Provide incentives for adopting hydrogen fuel cell trucks by covering the difference in cost between them and conventional diesel-powered vehicles.
- Encourage tandem fueling station and vehicle deployment, to ensure that one doesn’t need to exist before the other is in place, solidifying the overall fueling infrastructure.
- Collect data and establish benchmarks for various forms of fleet operation, helping to accelerate deployment by incentivizing private investment.
We could do with an Act like this in the UK.
But whereas the United States would start with hydrogen for trucks, we would probably start with hydrogen for buses.
World’s Largest Floating Offshore Wind Farm Fully Operational
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the first paragraph.
Located 15 kilometres off the coast of Aberdeenshire, Scotland, in water depths ranging from 60 metres to 80 metres, Kincardine is the largest operating floating wind farm.
Note.
- Wikipedia has a comprehensive section on floating wind turbines.
- Kincardine Wind Farm has a capacity of 50 MW.
- Its turbines are mounted on WindFloats, which were designed by Principle Power, who have this page on their web site, which describes advantages of the technology.
- The Kincardine wind farm appears to have been developed by Spanish company; Cobra and there are pictures on this page on their web site.
The WindFloats are triangular floating structures, which are based on semi-submersible offshore platform technology, that has been used in the offshore oil and gas industry since the early 1960s.
Semi-submersibles have good ship stability and seakeeping, so they would seem to be an ideal way to create a fixed structure in deep water on which to mount a wind turbine.
- The hull structure can be well below the surface of the sea, so they are not affected by waves.
- If they have a problem, it is handling changes of load on the platform. But this is an advantage with with wind turbines, as the load will be constant.
- Standard wind turbines can be used.
- All platform construction can be onshore rather than in the middle of a ferocious ocean.
- The platforms can be towed into position and moved into sheltered waters for servicing.
In Are Floating Wind Farms The Future?, which I wrote in 2020, I laid out my experience and views about floating wind farms.
I came to this conclusion.
It is my view, that floating wind farms are the future.
But then I’ve done the mathematics of these structures!
Did Boris’s advisors, as I doubt he knows the mathematics of oblique cylinders and how to solve simultaneous differential equations, do the mathematics or just read the brochures?
I will predict, that today’s structures will look primitive to some of those developed before 2030.
WindFloats seem to have fulfilled my predication and it’s only 2022.
How Big Can Floating Wind Turbines Get?
Platforms like WindFloat would appear to create a stable island that is as secure a mounting, as say a solid hill.
So I suspect that platforms can be created for the world’s largest wind turbines.
This article on offshoreWIND.biz is entitled World’s Largest, Most Powerful Wind Turbine Stands Complete.
This is the first paragraph.
With the final blade in place, the SG 14-222 DD prototype has become the world’s largest and most powerful turbine to be installed, taking the mantle from GE Haliade-X 14 MW prototype operating in the Port of Rotterdam, the Netherlands.
Note.
- This is a 14 MW turbine, that can be boosted to 15 MW.
- Kincardine Wind Farm has 5 x 9.5 MW and 1 x 2 MW turbines.
- Northern Horizons is talking about a 10 GW floating wind farm to the North-East of the Shetlands, that will use 20 MW turbines. The turbine visualisation on their web site, looks like it could be a WindFloat or similar technology.
How many 20 MW turbines does it need to carpet the seas around the UK?
Conclusion
Kincardine Wind Farm may be the world’s largest floating wind farm, but this won’t hold true for long.
- I can see various designs of semi-submersible platforms being developed, that will be able to support the world’s largest wind turbines.
- They will also be able to operate in the world’s deepest waters far out to sea.
- Northern Horizons talk of 20 MW turbines may sound ambitious, but I suspect that turbine engineers are already thinking bigger.
Offshore wind and its turbines will both have a huge future.
Mona, Morgan And Morven
The title of this post, may sound like a high-class firm of Welsh solicitors, but it is actually the names of three wind farms to be constructed by BP Alternative Energy Investments Ltd and Energie Baden-Württemberg AG.
Mona And Morgan
This EnBW-BP infographic describes the project.
Mona and Morgan do seem to have web page, which gives a simple map and a rather jargon-filled timeline.
Morven
This EnBW-BP infographic describes the project.
Morven does seem to have a web page, which gives a simple map and this statement.
The Morven wind farm is named after a mountain situated in the beautiful hills of Aberdeenshire, Scotland. The name derives from the Scottish Gaelic terms “Mhor” and “bheinn” meaning ‘big’ and ‘peak’, symbolic of the scale of opportunity represented by bp’s latest offshore wind project.
This article on Offshore Engineer is entitled ScotWind: BP, EnBW Win Bid to Build 2.9GW Morven Offshore Wind Farm.
This paragraph described the Morven wind farm.
The approximately 860km2 lease is located around 60km off the coast of Aberdeen. The E1 lease is in an advantaged area, allowing the partners to develop it as a fixed-bottom offshore wind project with a total generating capacity of around 2.9 gigawatts (GW), sufficient to power more than three million homes.
And this paragraph, described what BP will do with the energy.
“Along with the offshore wind development, these investments include significant expansion of electric vehicle charging infrastructure in Scotland and green hydrogen production. Together, these represent up to £10 billion of investment in support of offshore wind and Scotland’s energy transition,” BP added.
These are two large projects, but so far there is little else on the Internet, except for this press release.
Conclusion
Wind farms can be controversial and for this and other reasons, the general public need more information.
BP and EnBW can do much better.
Shell And ScottishPower Win Bids To Develop 5 GW Of Floating Wind Power In The UK
The title of this post, is the same as that of this press release from Shell.
This is three paragraphs from the press release.
Shell and ScottishPower have secured joint offers for seabed rights to develop large-scale floating wind farms as part of Crown Estate Scotland’s ScotWind leasing. The partners have won two sites representing a total of 5 gigawatts (GW) off the east and north-east coast of Scotland.
The new wind farms will be delivered through two joint ventures called MarramWind and CampionWind. They bring together ScottishPower’s and Shell’s decades of experience working offshore and significant presence in Scotland, as well as their strong innovation capabilities for delivering world-class offshore energy projects.
The development, construction and operation of ScotWind projects is set to bring new skilled jobs and manufacturing opportunities and boost local supply chains.
ScottishPower are actually involved in three large ScotWind projects; one by themselves and two in partnership with Shell.
MacHairWind
MachairWind is a project that Scottish Power is developing alone.
- It has its own page on the ScottishPower Renewables web site.
- It will be a 2 GW wind farm to the North-West of Islay.
- The turbines will be on fixed foundations.
I wrote about this project in MacHairWind Wind Farm.
MarramWind And CampionWind
These two wind farms are being developed in partnership with Shell.
They both have their own web sites.
MarramWind’s web site has this introduction.
ScottishPower and Shell have joined forces to develop the MarramWind offshore windfarm following success in the recent ScotWind auction process by Crown Estate Scotland.
Located 75 kilometres off the North East coast of Scotland in water depths averaging 100 metres, the proposed MarramWind floating offshore windfarm could deliver up to 3 gigawatts (GW) of cleaner renewable energy.
This map clipped from the MarramWind web site, shows the location of the wind farm.
CampionWind’s web site has this introduction.
ScottishPower and Shell have joined forces to develop the CampionWind offshore windfarm following success in the recent ScotWind auction process by Crown Estate Scotland.
Located 100 kilometres from the east coast of Scotland, in water depths averaging 77 metres, the proposed CampionWind floating offshore windfarm could deliver up to 2 gigawatts (GW) of cleaner renewable energy.
This map clipped from the CampionWind web site, shows the location of the wind farm.
Note.
- The two wind farms will be within a few miles of each other.
- Both wind farms will use floating wind turbines.
- The water is a bit deeper at MarramWind, but this surely doesn’t bother a floating turbine.
- MarramWind and CampionWind will have a total capacity of 5 GW.
- Hywind Scotland is the world’s first commercial wind farm using floating wind turbines, situated 29 kilometres off Peterhead. This wind farm is only 30 MW, but in its first years of operation has achieved a capacity factor of over 50 %.
- The proposed turbines at Northern Horizons‘ 10 GW wind farm, which is 130 kilometres to the North-East of Shetland will be 20 MW giants and nearly as tall as The Shard in London.
So will Scottish Power and Shell design and build a combined field, similar in concept to Northern Horizons’ wind farm, using an armada of 250 floating wind turbines?
- The wind turbines might be moored around a fixed or floating mother platform or structure, that will collect the electricity and deliver it to the shore.
- Turbines could be serviced in situ or moved into port, as needed.
- Extending the wind farm could just be a matter of mooring the extra turbines in position and then connecting them to the mother platform.
- Is there a convenient disused oil or gas platform, that could be repurposed as the mother platform?
It certainly would appear to be a way of building large offshore fields in deep waters.
Where Would The Combined MarramWind And CampionWind Rank In Terms of UK Wind Farms?
Consider.
- MarramWind and CampionWind will have a total capacity of 5 GW.
- Phase one of the Hornsea Wind Farm is the largest offshore wind farm in the world, with a capacity of just over 1.2 GW and when complete it will have a capacity of 6 GW.
- Northern Horizons is planned to be 10 GW.
- The East Anglian Array could be as large as 7.2 GW.
- The Dogger Bank Wind Farm is planned to be as large as 4.8 MW.
- Norfolk Vanguard and Norfolk Boreas are a pair of 1.8 GW wind farms.
- MacHairWind will be a 2 GW wind farm.
Note.
- This is not a complete list of large wind farms in the development pipeline.
- BP have obtained leases, but have not published their plans.
- Most farms under development are at least one GW.
- These farms are a total of 38.6 GW.
The Combined MarramWind and CampionWind would be one of several large wind farms around 5 GW.
There Is A Desperate Need For Energy Storage
If we are generating upwards of 40 GW of wind and solar energy in the UK, there will be a desperate need for energy storage to cover for the times, when the wind doesn’t blow and the sun doesn’t shine.
Scotland should be OK, as there are various energy storage projects in development.
- The 1.5 GW/ 30 GWh Coire Glas project is according to SSE shovel-ready and has planning permission.
- The 450 MW/2.8 GWh Red John project is being constructed.
- Drax, ILI Group and SSE have several other projects under development.
So what would happen in the South?
The government appears to be on the case as I wrote in Ministerial Roundtable Seeks To Unlock Investment In UK Energy Storage.
But there is also the possibility of using hydrogen.
- Hydrogen could be created by a series of giant electrolysers.
- It could be blended with natural gas to eke out our natural gas and save carbon. According to HyDeploy, it appears that up to 20 % can be added, without needing to change boilers and appliances.
- It can be stored in depleted offshore gas fields.
- It can be used to power heavy transport like buses, trucks, trains and ships.
- It can be burned in gas-fired power stations to generate electricity.
Hydrogen can also be used as a feedstock or green energy source for the making of chemicals, concrete and steel.
Conclusion
We are approaching the end of the first phase of the development of renewable energy in the UK.
Massive floating wind farms using armadas of floating wind farms, a large expansion of pumped storage hydro and a huge expansion of the use of hydrogen will see us through to a carbon-free future.
The Anonymous Widower
