Is Something Happening At Highview Power?

It seems to be impossible to connect to the Highview Power web site.

I get the message, that my security is not private.

There is also no news of the company in the last month.

The Next Generation Of Fixed Foundation Wind Farms

This article on offshoreWIND.biz, is entitled Offshore Wind Turbines In 2022: 15 MW Prototypes Starting To Spin In Europe, Chinese Rolling Out 16 MW Models, Windcatcher And VAWTs Secure Demo Projects.

The title itself, shows 15-16 MW wind turbines and the text lists three European 15 MW and two Chinese 16 MW wind turbines, that are being developed.

This paragraph also indicates that Siemens Gamesa are in the running for orders.

So far, the SG 14-236 DD wind turbine has 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.

Large turbines with a capacity of 15 MW and upwards appear to be becoming the new normal.

Water depths for these large turbines are forecast to be deeper than the two Norfolk wind-farms, which are between 22 and 40 metres.

This means that foundations will get much larger and heavier.

This article on offshoreWIND.biz, is entitled New Monopile Installation Method Attracts Major Backer, describes a new generation of monopiles as 100-130 metres in length, 12-15 metres in outer diameter, and a weight of up to 5,000 tonnes.

Installing these long and heavy objects safely in deep waters, is not a job for the faint-hearted.

The article describes a new method of installation, which I feel is very elegant.

  • The XXXL monopiles are built horizontally.
  • They are moved on to the jack-up ship by self-propelled modular transporters (SPMT).
  • It appears at least two or possibly up to four monopiles can be carried on the ship.
  • They are lifted into the vertical position by a lifting beam.

Note.

  1. No cranes are involved in the process.
  2. The lifting beam method of erecting the 5,000 tonne XXXL monopile is simple and very efficient.
  3. Self-propelled modular transporters were used to install the 2000 tonne subway at Hackney Wick station.
  4. Rollers are fitted on the ship to ease handling of the monopiles.

I can certainly see this specialised jack-up ship speeding up the installation of these giant monopiles.

Consequences For Floating Wind

I do wonder, if this method of installing fixed foundation wind farms, will allow larger foundations and these may mean that there is less need for the more complex floating wind farms.

Gravitricity Makes Hydrogen Play With FlexiStore

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

This is the sub-heading.

Edinburgh-based energy storage firm Gravitricity is looking to green hydrogen, bringing a new underground storage solution to market.

The system is explained with a large graphic, showing an electrolyser, a FlexiStore and a hydrogen filling station, with this paragraph underneath.

Known as FlexiStore, the concept involves purpose-built, steel-lined shafts capable of holding up to 100 tonnes of compressed hydrogen at 220 bar – around 3.33GWh of energy, or enough to refuel over 1,000 HGVs, according to Gravitricity. Unlike naturally occurring underground storage like salt caverns, FlexiStores could be positioned anywhere, with the current plan to co-locate the storage as close as possible to renewable generation. Gravitricity says a single FlexiStore could serve a 460MW wind farm and that 1,000 units could meet the UK’s predicted hydrogen storage needs in 2050.

Note.

  1. The concept certainly solves the problem of storing hydrogen on a country-wide basis.
  2. I suspect, a machine could be designed and built to create the shafts.
  3. A 3.33 GWh store could supply 460 MW for nearly 33 hours. As a Control Engineer, that sounds a good balance for backing up a wind farm!

As ARUP has been involved in a feasibility study, I suspect there’s a fair chance that FlexiStores can be built.

Norway’s Answer To Wind Power Intermittency Lies Offshore – Study

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

This is the first paragraph.

SINTEF has revealed in its recent study that there is no statistical covariation or systematic correlation in time between the occurrence of offshore wind conditions in southern and northern Norway, and adds that this knowledge will increase the commercial value of Norwegian offshore wind energy.

It does seem lucky for the Norwegians, that their wind farms appear to be able to supply a more constant amount of electricity, than many of those against wind farms would have you believe.

I hope that a reputable UK agency or university, is doing a similar analysis for UK wind farms.

World’s First Floating Offshore Wind Farm Celebrates Five Years Of Operation

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

This is the sub-heading.

Hywind Scotland, the first floating offshore wind farm in the world, has passed five years in operation since its commissioning in 2017.

And this is the first paragraph.

According to Equinor, Hywind Scotland is the world’s best-performing offshore wind farm, achieving a capacity factor of 54 per cent over its five years of operations.

Note.

  1. Hywind Scotland is a 30 MW wind farm with five turbines.
  2. The capacity faction is much higher than a windfarm with fixed foundations.
  3. The water depth is between 95 and120 metres.
  4. The wind farm is 30 km. off Peterhead.

There is at least 15 GW of floating wind farms being planned in UK waters before 2030.

Conclusion

The wind farm has made a good start for the first floating wind farm.

Danes Talk 62 MW Offshore Wind Turbines For North Sea Energy Island

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

The Danes may talk 62 MW, but that four times larger than one of the biggest today, that I wrote about in Vestas 15 MW Prototype Turbine Produces First Power.

This paragraph says a bit more about the 62 MW turbine.

According to the DEA’s framework document for the draft plan for the strategic environmental assessment (SEA), this could be a 500-metre-tall wind turbine with a rotor diameter of 480 metres and a capacity of up to 62 MW.

This turbine is bigger in terms of capacity, than  than some whole farms.

Ofgem OKs Transmission Investments Needed For UK’s 2030 Offshore Wind Target

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

This is the sub-heading.

Ofgem has approved the strategic electricity transmission reinforcements required to deliver the UK Government’s 50 GW offshore wind by 2030 target, set out as part of the regulator’s Accelerated Strategic Transmission Investment (ASTI) framework.

A map then shows the principle new transmission reinforcements.

These include two 2 GW subsea HVDC links from Peterhead to England, both of which will be taken forward as joint ventures with National Grid Electricity Transmission (NGET), a 2 GW subsea HVDC link from Spittal in Caithness, connecting to Peterhead, as well as a 1.8 GW subsea HVDC link from Arnish on the Western Isles to the Beauly area near Inverness.

The approval also implies 400 kV onshore reinforcements, between Beauly, Blackhillock, New Deer and Peterhead; between Beauly, Loch Buidhe and Spittal; and between Kintore, Tealing and Westfield; and uprating the existing Beauly to Denny line to enable 400 kV operation on both circuits.

All cables seem to lead to Peterhead.

Carbon Capture And Storage Projects Across Europe

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

 

Twenty separate projects are named in eleven different countries.

Some may believe carbon capture and storage is a waste of time and money, but there is a large amount of investment going into the technology.

Brown Seaweed Could Remove 550 Million Tons Of Carbon

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

This may seem like a story that has arrived a few months early.

But the report does come from the respect Max Planck Institute for Marine Microbiology.

The research is detailed on this page on their web site, which is entitled Slime For The Cli­mate, De­livered By Brown Al­gae.

It is introduced by this sub-heading.

In form of fuc­oidan, brown al­gae could re­move up to 550 mil­lion tons of car­bon di­ox­ide from the at­mo­sphere every year.

Which is followed by this paragraph.

Brown algae take up large amounts of carbon dioxide from the air and release parts of the carbon contained therein back into the environment in mucous form. This mucus is hard to break down for other ocean inhabitants, thus the carbon is removed from the atmosphere for a long time, as researchers at the Max Planck Institute for Marine Microbiology in Bremen now show. They reveal that the algal mucus called fucoidan is particularly responsible for this carbon removal and estimate that brown algae could thus remove up to 550 million tons of carbon dioxide from the air every year – almost the amount of Germany’s entire annual greenhouse gas emissions.

Note that fucoidan has a Wikipedia entry.

The page says this about brown algae.

Brown al­gae are true won­der plants when it comes to ab­sorb­ing car­bon di­ox­ide from the air.

It does seem to me that the Germans are on to something.

Vestas 15 MW Prototype Turbine Produces First Power

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

This is the introductory paragraph.

Vestas’ V236-15.0 MW prototype wind turbine has produced its first kWh after being fully assembled at the Østerild National test centre for large wind turbines in Western Jutland, Denmark.

The first of the four wind farms in the Hornsea wind farm complex to be developed is Hornsea One.

  • It has a capacity of 1218 MW.
  • It is comprised of 174 Siemens SWT-7.0-154, which each have a generating capacity of 7 MW.

If 15 MW turbines could have been used on Hornsea One, it would have more than doubled the generating capacity to 2625 MW.

But obviously, larger turbines have longer blades, so they may need to be placed further apart.

In Vattenfall Boosts Capacity For Norfolk Offshore Wind Zone, I write about how Vattenfall are increasing the size of their Norfolk wind farms, by proposing to use larger turbines.

Conclusion

Turbines will get larger and 15 MW turbines will be commonplace.

A possible advantage is that you only need sixty-seven turbines for a GW, as opposed to a hundred 10 MW turbines, so there are possibilities to optimise the most profitable way to build a wind farm.
