X1 Wind’s Floating Prototype Delivers First Power Offshore Canary Islands

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

This is the sub-heading.

X1 Wind has announced that its floating offshore wind turbine prototype delivered first power to PLOCAN’s smart grid in the Canary Islands, Spain.

The article is based on this news item from X1 Wind, which is entitled X1 Wind’s X30 Floating Wind Prototype Delivers First kWh, which starts with these two paragraphs.

X1 Wind has announced today (MARCH 07) that its X30 floating wind prototype, installed in the Canary Islands, successfully produced its first kWh.

The milestone marks the world’s only floating wind platform currently installed with a TLP mooring system, which dramatically reduces the environmental footprint and improves compatibility with other sea uses. It further heralds Spain’s first floating wind prototype to export electricity via a subsea cable.

Note.

  1. TLP is short for tension leg platform, which is described in this Wikipedia entry.
  2. The TLP Wikipedia entry contains a section, which describes their use with wind turbines.
  3. TLPs have been in use for over forty years, with the first use in the Hutton field in the North Sea.
  4. TLPs work well for water depths of between 300 and 1,500 metres.

I also suspect there’s a lot of experience from the oil and gas industry around the world about how to deploy TLPs.

The X1 Wind news item also has this paragraph.

The novel X30 platform is equipped with a specially adapted V29 Vestas turbine and ABB power converter. Another key design feature, developed through the EU-backed PivotBuoy Project, combines advantages of SPM and TLP mooring systems. The proprietary SPM design enables the floater to ‘weathervane’ passively and maximise energy yields, with an electrical swivel ensuring electricity transfer without cable twisting. The TLP mooring system also dramatically reduces the seabed footprint, compared to traditional designs proposing catenary mooring lines, minimizing environmental impact while maximizing compatibility with other sea uses, in addition to its suitability to move into deeper waters.

SPM is short for single point mooring, which is described in this Wikipedia entry, where this is the first sentence.

A Single buoy mooring (SrM) (also known as single-point mooring or SPM) is a loading buoy anchored offshore, that serves as a mooring point and interconnect for tankers loading or offloading gas or liquid products. SPMs are the link between geostatic subsea manifold connections and weathervaning tankers. They are capable of handling any tonnage ship, even very large crude carriers (VLCC) where no alternative facility is available.

Note.

  1. The use of the weathervane in both paragraphs.
  2. If an SPM can handle a VLCC, it surely can handle a well-designed floating structure with a wind turbine mounted on top.
  3. I suspect that an SPM used for a wind turbine will be much simpler than one used to load or unload a gas or oil tanker.

As with TLPs, I also suspect there’s a lot of experience from the oil and gas industry, from around the world about how to deploy SPMs.

It looks to me, that X1 Wind have used the proven attributes of SPMs and TLPs to create a simple mooring for a wind turbine, that is designed to align itself with the wind.

X1 Wind Are Open With Their Technology

Today’s news item from X1 Wind also links to two other useful documents.

They are certainly open with their information.

The news item, also includes this video.

 

Thoughts

These are some thoughts.

Capacity Factor

The capacity factor of this wind turbine could be an interesting figure.

As the turbine constantly will turn to be downwind, this should maximise the amount of electricity produced over a period of time.

Tetrahedrons

The design is effectively a tetrahedron.

Alexander Graham Bell knew a lot about the properties of tetrahedrons and invented the tetrahedral kite.

This document details Bell’s involvement with tetrahedrons and says this.

Bell found the tetrahedron to have a very good strength to weight ratio.

Put more simply this means that an object is structurally very strong but at the same time very lightweight.

So X1 Wind’s design is probably extremely strong for its weight.

Large Turbines

X1 Wind’s prototype uses a wind turbine of only 225 KW.

Manufacturers are building 15 or 16 MW turbines now and talking of 20 MW in the next few years.

Given the strength of the tetrahedron, I wonder, if it will be possible to build a PivotBuoy, that is capable of hosting a 20 MW wind turbine?

Conclusion

Although it appears radical, it uses proven technology to generate power in an innovative way.

In some ways the thinking behind the design of this floating technology, is a bit like that of Issigonis in his design for the first Mini, where he took proven technology and arranged it differently to perform better.

Gondan Shipyard Launches Another Hydrogen-Ready CSOV

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

This is the sub-heading.

Gondan Shipyard has launched another commissioning service operation vessel (CSOV) it is building for the Norwegian shipowner Edda Wind at its yard in Figueras, Spain.

Increasingly smaller ships are being built hydrogen-ready, so they can be converted to zero-carbon, when the technology is developed.

Over the last couple of years companies like Cummins, JCB and Rolls-Royce mtu have developed diesel engines that can be converted to hydrogen engines.

Cummins talk of agnostic engines, which are identical from the cylinder head gasket down and what is above it, can make the engine, diesel, hydrogen on natural gas powered.

Baltic States Agree To Develop Plan To Railway Network’s Conversion According To EU Standards

The title of this post is the same as that of this article on Baltic News Network.

These are the first two paragraphs.

During a meeting of European transport ministers in Brussels, participants agreed that all member states the railway network of which differs from the EU standard, have until 2025-2026 to develop a plan to transition to 1 435 mm. This applies to Latvia as well, as reported by Ministry of Transport.

Latvia and other Baltic States still have railway networks built in accordance with Russian standard of 1 520 mm, whereas the majority of other European countries have railway standard of 1 435 mm. This is also the standard that will be used for the Rail Baltica line.

I have some thoughts.

  1. Putin won’t like it, as his trains won’t fit the gauge, so it will cramp his invasion plans.
  2. Will gauge change apply to Spain and Ireland?
  3. If the Irish Republic converts, will Ulster say no? Undoubtedly they will!
  4. Will it also apply to trams, as there are quite a few metre gauge tramways.

I doubt that it will ever happen everywhere.

Ørsted Signs Two ‘Industry First’ Monopile Contracts For Hornsea 3 Foundations

The title of this post, is the same as that of this press release from Ørsted.

This is the introductory paragraph.

Ørsted, the world’s most sustainable energy company, has signed two ‘industry first’ contracts for the fabrication of XXL monopile foundations for the Hornsea 3 offshore wind farm.

I have a few thoughts about the press release.

XXL Monopile Foundations

These four paragraphs describe Hornsea 3’s XXL monopile foundations.

Subject to Ørsted taking a Final Investment Decision on Hornsea 3, the contracts have been finalised with Haizea Wind Group, through its subsidiary Haizea Bilbao, and SeAH Wind Limited, a UK-based subsidiary of SeAH Steel Holdings (SeAH).

Ørsted will be the first major customer at SeAH Wind’s new monopile facility in Teesside, and the agreement with Haizea marks the company’s first XXL monopile contract with Ørsted.

The deal with SeAH represents the single largest offshore wind foundations contract secured by any UK company. Haizea’s agreement is the largest single contract ever secured by Haizea Wind Group.

Each of the huge foundation structures for Hornsea 3 will weigh between 1,300 and 2,400 tonnes and measure in at between 83 and 111 metres in length. Monopile production is expected to start in 2024.

Note

  1. These are huge steel structures.
  2. But then the water depth appears to be between 36 and 73 metres.
  3. It looks like the orders are shared between Spanish and Korean companies

This article on offshoreWIND.biz, is entitled Beyond XXL – Slim Monopiles For Deep-Water Wind Farms.

These are some points from the article.

  • XXL-Monopiles have been successfully used for water depths of up to 40 metres. Now wind farm developers need monopiles “beyond XXL”.
  • The extension of the range is needed, mainly to enable the use of larger turbines, deeper water, and harsher environmental situations.
  • These monopiles will allow turbines of up to 15 megawatts with rotor diameters of up to 230 metres.
  • This monopile design automatically induces the idea of design and fabrication optimisation to ensure that monopiles continue to lead the ranking of most economical foundation systems.

In the 1970s, I was involved with a Cambridge University spin-out company called Balaena Structures, who were using similar much larger structures to support oil and gas production platforms.

I was just doing calculations, but I do wonder if these XXL monopile foundations, owe things in their design to work done by structural engineers, like those I met at Cambridge fifty years ago.

Are These Two Stories Related?

These are two stories recently published in Railway Gazette.

Deutsche Bahn Sells Arriva Businesses To Private Equity Holding Company, which starts with this paragraph.

Deutsche Bahn has reached agreement to sell its Arriva local transport activities in Denmark, Poland and Serbia to München-based private equity holding company Mutares SE & Co KGaA.

That is fairly clear and is probably related with the German government’s desire for DB to concentrate on its core business.seren

This article on Railway Gazette is entitled RENFE Looks At Entering UK Rail Market Through Open Access Partnership, which starts with this paragraph.

Open access passenger service developer Grand Union Trains is working with Spain’s national operator RENFE and private equity firm Serena Industrial Partners on a proposed service between London and Wales.

That also is fairly clear and would bring competition to services to and from South Wales.

It would also help in the financing of Grand Union Trains.

The article also says the following.

  • RENFE seem to be expanding into partnerships to run services outside Spain.
  • A parkway station at Felindre will be build to avoid the reverse at Swansea, that would save 20 mins.
  • It will be a high quality service with new electro-diesel trains.
  • Four trains will be needed.
  • A 2025 start is envisaged.

Will this partnership with Grand Union Trains proceed with the development of Grand Union Trains’ London and Stirling service?

I have some thoughts and questions.

Will Deutsche Bahn Sell Other Arriva Businesses?

I think this is a reasonable question to ask, especially, as Deutsche Bahn owns two Open Access Operators in the UK; Chiltern Railways and Grand Central Trains.

  • Both operators have a good reputation.
  • Both operators need to decarbonise, either by updating their current stock or buying new trains.
  • Both operators have solid niche markets, where they are often responsible for the stations.
  • Both operators have expansion plans.

Would RENFE and Serena Industrial Partners be interested in taking over Arriva UK and developing the business?

The Talgo Factory At Longannet

I believe that there is reason to believe that one of Talgo’s reasons for a factory in Scotland, is that it could have been used to build Russian and dual-gauge trains for Eastern Europe. The trains would have been delivered by ferry from Rosyth.

There is also the not-small matter of the fleet for Rail Baltica, for which Talgo will surely be a bidder.

But Russia’s attack on Ukraine has scuppered that plan, or at least delayed it for a few years. But now, there could be a much larger market for trains in Eastern Europe and especially Ukraine.

If RENFE Acquire Open Access Operators In The UK, They Will Need New Trains

They will certainly need new trains for the South Wales operations, if they go ahead, but if they were to decarbonise Chiltern and Grand Central, the order could be substantial.

With one Spanish train factory in the UK and another a possibility, I would suspect any train order would go to a Spanish train-builder.

If the orders fell right, could we see Talgo’s factory at Longannet built after all?

IberBlue Wind Launches In Spain And Portugal With The Objective Of Promoting Iberian Leadership In Floating Offshore Wind

The title of this post is the same as that of this press release from the Simply Blue Group.

These three paragraphs introduce the project.

Simply Blue Group, Proes Consultores and FF New Energy Ventures have formed a joint venture that brings together expertise in all phases of floating offshore wind farm development.

The joint venture will focus its operations in Spain on Andalusia and Galicia, while in Portugal it will focus on the central and northern parts of the country.

IberBlue Wind aims to develop around 2GW of floating offshore wind farms.

This paragraph describes the plans of the Irish company; Simply Blue Group.

Simply Blue Group is a global developer of floating offshore wind farms with projects in Ireland, UK, US, Poland, and Sweden. Simply Blue Group currently has a pipeline of 10GW of projects under development. As part of its growth strategy, the company is now expanding into the Spanish and Portuguese markets.

It appears to be a very ambitious company.

Every GW of renewable energy helps.

SSE Renewables Completes Acquisition Of European Renewable Energy Development Platform

The title of this post, is the same as that of this press release from SSE.

This paragraph introduces the deal.

SSE Renewables has completed the transaction with Siemens Gamesa Renewable Energy (SGRE) to acquire its existing European renewable energy development platform for a consideration of €580m.

I have a few thoughts.

Why Have Siemens Gamesa Sold Their European Renewable Energy Development Platform?

This article on Renewables Now is entitled Siemens Gamesa Wraps Up Sale Of 3.9-GW Wind Portfolio To SSE Renewables, gives a reason.

For the turbine maker, the sale represents one of the measures implemented to rein in profit losses quarter after quarter due to internal challenges, high costs and supply chain issues.

As with many things, it appears to be all about the money.

Can SSE Renewables Afford It?

Consider.

SSE seem to have found a Scottish magic money tree.

€580m is just small change.

What Projects Are Included In The Deal?

This is a paragraph from the press release.

The SGRE portfolio includes c.3.8GW of onshore wind development projects – around half of which is located in Spain with the remainder across France, Italy and Greece – with scope for up to 1.4GW of additional co-located solar development opportunities. Development of the portfolio of projects has continued to progress since the acquisition was announced in April, with additional opportunities identified and permits and grid connections advancing. Over 2GW of the total pipeline is considered to be at a secured stage, where a grid connection or land agreement has been secured or relevant permits granted.

Note.

  1. As an engineer, I note that there is no offshore wind, which surely is the renewable energy development with most risk and installation costs.
  2. SSE Renewables have a lot of experience of onshore wind, so delivering and financing the extra 3.8 GW, shouldn’t be a problem.
  3. The 1.4 GW of solar comes with the word co-located. Wind and solar together, perhaps with a battery must surely be a good investment in the sunnier climes of Europe.

It doesn’t look to me that SSE Renewables have bought a load of assets that no-one wants.

I do wonder thought, if Siemens Gamesa were having trouble progressing this large diverse portfolio of projects, due to a shortage of resources like money and engineers.

So are SSE finishing off a few projects and they can transfer a few engineers to these projects?

Are SSE Spreading The Risk?

SSE operate mainly in the UK and Ireland, so is adding Spain, France, Italy and Greece a good idea?

Of the four new countries, it’s unlikely that all will perform well, but a mixed portfolio is usually a good idea.

Will SSE Renewables  Buy Siemens Gamesa Turbines In The Future?

SSE Renewables seem to do an individual deal on each wind farm, as no one manufacturer dominates.

But now Siemens Gamesa may be more financially stable, perhaps they can get a better deal for the turbines they want.

Conclusion

I don’t think SSE Renewables have done a bad deal.

New Proton Ceramic Reactor Stack For Highly Efficient Hydrogen Production And Carbon Capture In A Single Step

The title of this post, is the same as that of this article on Green Car Congress.

This is the opening paragraph.

A team of researchers from CoorsTek Membrane Sciences and SINTEF in Norway, and Universitat Politècnica de València in Spain, has demonstrated a 36-cell well-balanced proton ceramic reactor stack enabled by a new interconnect that achieves complete conversion of methane with more than 99% recovery to pressurized hydrogen, leaving a concentrated stream of carbon dioxide. The team has also demonstrated that the process can be scaled up for commercial application.

A paper has been published in the journal; Science.

I find this concept interesting for a number of reasons.

  • I’ve believed for some time, that applications, that need a good supply of pure carbon dioxide will be developed. One obvious use is feeding it to plants in large greenhouses, so we can have our CO2 and eat it!
  • 99 % is a very high efficiency.
  • Ammonia, natural gas or biogas can be used as a feedstock.

Coors were an Artemis user for project management and I had an enjoyable few days Golden, Colorado and at the Coors brewery, sometime in the 1980s.

  • It was then that I first heard of CoorsTek, who used to make ceramics for the US defence industry.
  • In those days, the beer was made to German brewing rules and was unpasteurised.
  • The beer had to be delivered to customers within a certain time, so long distance deliveries used trains.
  • Coors Brewing Company has since merged with Molson, but CoorsTek appears to be still owned by the Coors family.
  • I had taken a few small bottles of Adnams Broadside with me and one of their managers analysed one before drinking the rest of the bottle. He informed me that it was a felony to be in possession of such a strong beer in Colorado.

Coors were and probably still are in some ways not your average brewing company.

Coors News Item On Proton Ceramic Membranes For Hydrogen Production

This page on the CoorsTek web site, which is entitled Proton Ceramic Membranes For Hydrogen Production Published In ‘Science’, gives more details.

Conclusion

This technology could be massive.

Will We See More Multi-Country Renewable Energy Deals?

In this blog, I have talked about various deals, where two or more countries and/or companies are getting together to generate electricity in one country and transfer it to another, either as electricity or as hydrogen

Examples include.

There are also all the hydrogen deals done by Fortescue Future Industries.

Where Are There Possibilities Of More Multi-Country Renewable Energy Deals?

These are a few serious possibilities.

Argentina

This is an extract from this page on Wind Energy International, which is entitled Argentina.

Argentina has an estimated technical wind energy potential of 300 GW. In southern Patagonia (Chubut and Santa Cruz provinces), average wind speeds range between 9.0 and 11.2 m/s, whereas in the north (Neuquén and Río Negro provinces), wind speeds range from 7.2 to 8.4 m/s. The general average capacity factor for Argentina is 35% and in the Patagonia region it ranges between as much as 47% and 59%. Especially in Northwest Patagonia, locally known as the Comahue region, hydro and wind may seasonally complement each other and.benefit both technologies. One other promising region for wind power development is the Atlantic sea coast.

As I wrote in Australia’s FFI Plans $8.4 Billion Green Hydrogen Project In Argentina, it appears that Andrew Forrest and FFI are already on the ground.

Australia

There are already three major schemes based on Australia and I am certain they will be more. Especially, as Japan, Korea, Malaysia and Singapore will need the zero-carbon energy.

It would appear that except for the Australia-Asia PowerLink, the energy will be transferred as liquid hydrogen or liquid ammonia.

Bangladesh

Bangladesh wouldn’t be on the lists of many, where ideal countries for renewable energy are being discussed.

But, this report on Energy Tracker Asia is entitled The Renewable Energy Potential of Bangladesh, where this is said.

A report investigating the renewable energy technical capacity of Bangladesh found that the country could deploy up to 156 GW of utility-scale solar on 6,250 km2 of land and 150 GW of wind. Offshore wind power would account for 134 GW of this total capacity.

I wouldn’t be surprised to see Bangladesh, supplying renewable energy to the East, with international companies and organisations developing the renewable infrastructure.

I think it should be noted that international companies flock to countries, where the investment opportunities are good. That has happened in the UK, with offshore wind, where many wind farms have been developed by companies such as Equinor, Iberola, RWE and Wattenfall.

Chile

Chile has started to develop the 100,000 square kilometres of the Atacama Desert for solar power and I wrote about this in The Power Of Solar With A Large Battery.

This sentence in the Wikipedia entry for Energy In Chile, illustrates the potential of solar power in the Atacama Desert.

In 2013, Total S.A. announced the world’s largest unsubsidised solar farm would be installed with assistance from SunPower Corp into Chile’s Atacama desert.

I also wrote Chile Wants To Export Solar Energy To Asia Via 15,000km Submarine Cable, about Chile’s ambitions to supply Asia with energy.

Ethiopia

Andrew Forrest of Fortescue Future Industries is on the case, as I wrote in Fortescue Future Industries Enters Ethiopia to Produce Green Energy.

North Africa

Consider.

  • The major North African countries of Morocco, Algeria, Tunisia, Libya and Egypt, all have and depend on to a certain extent on fossil fuels.
  • There are gas pipelines to Spain and Italy.
  • Morocco will be the Southern end of the Morocco-UK Power Project, if it gets developed.
  • All five countries have some nuclear power stations.
  • All five countries have lots of sun for solar power.
  • Some Saharan countries to the South of Morocco, Algeria and Libya could also provide energy from the sun.
  • Egypt has substantial hydro-electric power on the River Nile.
  • Egypt will be connected to Greece through the EuroAfrica Interconnector.

I believe that a well-designed and co-ordinated project could generate a lot of electricity and hydrogen for Europe and bring much-needed income and employment to North Africa.

I feel that if the Morocco-UK Power Project can be successfully built, then this could create a flurry of activity all over North Africa.

Saudi Arabia

Saudi Arabia has a problem. As the rest of the world moves away from fossil fuels in the next few decades, they will see the revenues from oil and natural gas come under pressure.

But as a rich country, with 2.15 million km² of land and lots of sun, they must have some potential to generate solar electricity.

In the Wikipedia entry for Solar Power In Saudi Arabia, this is said.

The Saudi agency in charge of developing the nations renewable energy sector, Ka-care, announced in May 2012 that the nation would install 41 gigawatts (GW) of solar capacity by 2032.[2] It was projected to be composed of 25 GW of solar thermal, and 16 GW of photovoltaics. At the time of this announcement, Saudi Arabia had only 0.003 gigawatts of installed solar energy capacity. A total of 24 GW of renewable energy was expected by 2020, and 54 GW by 2032.

Wikipedia also says that Saudi Arabia also has nuclear ambitions.

I can see that Saudi Arabia will replace some of their oil and gas exports with green hydrogen.

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.
