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.
- TLP is short for tension leg platform, which is described in this Wikipedia entry.
- The TLP Wikipedia entry contains a section, which describes their use with wind turbines.
- TLPs have been in use for over forty years, with the first use in the Hutton field in the North Sea.
- 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.
- The use of the weathervane in both paragraphs.
- If an SPM can handle a VLCC, it surely can handle a well-designed floating structure with a wind turbine mounted on top.
- 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.
- X1 Wind Adaptation Of A Vestas V29 Turbine To Downwind Configuration
- X1 Wind Successfully Installs Floating Wind Platform In Spain
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.
Ørsted Joins Global Offshore Wind Alliance
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Ørsted has become the first energy company to join the Global Offshore Wind Alliance (GOWA) to support a faster deployment of offshore wind and create a global community of action.
These two paragraphs outline GOWA.
GOWA is a new global organisation that brings together governments, the private sector, international organisations, and other stakeholders to accelerate the deployment of offshore wind power.
The alliance was launched last year at COP27 by the International Renewable Energy Agency (IRENA), the Global Wind Energy Council (GWEC), and the Danish government.
For more information look at the GOWA web-site.
Green Light For Orkney Transmission Link
The title of this post, is the same as that of this news item from SSE.
These three paragraphs outline the project.
SSE’s Transmission business, SSEN Transmission, has welcomed today’s publication by Ofgem in which the energy regulator has provisionally approved long awaited and much needed plans to provide a subsea electricity transmission link to Orkney.
The Orkney Islands are home to some of the world’s greatest resources of renewable electricity, from established onshore wind, to emerging marine technologies, where Orkney is at the forefront of global developments in marine energy generation.
Following significant growth in small-scale renewable electricity generation in Orkney, the local electricity network has long been at full capacity and no new electricity generation can connect without significant reinforcements.
This paragraph describes the scope of the project.
SSEN Transmission’s proposed solution would enable the connection of up to 220MW of new renewable electricity and consists of a new substation at Finstown in Orkney, and around 57km of subsea cable, connecting to a new substation at Dounreay in Caithness.
200 MW seems a good return for a substation and forty miles of cable.
SSE Thermal Is Charting A Path For Low-Carbon Flexible Generation In Ireland
The title of this post, is the same as that of this news item from SSE.
This is the sub-heading.
SSE Thermal, as part of SSE plc, is exploring options to develop two new low-carbon power stations in Ireland which would help to protect security of supply and provide flexible backup to renewable generation.
This three paragraphs outline the project.
Sites in Tarbert in County Kerry and at Platin in County Meath, could provide the location for these new power stations, which would initially run on sustainable biofuel with the potential to convert to hydrogen in the future.
Biofuel provides a lower carbon option for use in power stations, using waste feedstocks to produce valuable flexible electricity making it an important transitionary solution as plans for a greater use of hydrogen and carbon capture are developed. The proposed units will run on Hydrotreated Vegetable Oil (or HVO), which is produced by processing waste oils to create a fossil-free alternative to diesel in accordance with EU sustainability standards.
Development at the two sites could provide up to 450MW of new generation capacity to the grid, with up to 300MW at Tarbert and 150MW at Platin. While in early development and still subject to a final investment decision, these new power stations could be operational as early as 2027, bringing with them the potential to underpin demand for low-carbon hydrogen in Ireland.
One problem is that SSE’s existing Tarbert Power Station is required to close by the end of 2023 in line with its environmental licence. So it looks like they’ll have to get going quickly.
Lessons From Keadby 2
Keadby 2 is one of SSE Thermal’s newest power stations and it is described in this page on the SSE Thermal web site, which is entitled Keadby 2 Power Station.
These are first three paragraphs from the page.
Keadby 2 is a new 893MW gas-fired power station in North Lincolnshire currently being constructed by our EPC contractor Siemens Energy. The project is adjacent to our operational Keadby 1 Power Station.
SSE Thermal has partnered with Siemens Energy to introduce first-of-a-kind, high-efficiency gas-fired generation technology to the UK. When completed, Keadby 2 is expected to become the cleanest and most-efficient gas-fired power station in Europe.
The station will also be capable of being upgraded to further decarbonise its generation through carbon capture or hydrogen technology, as routes to market develop.
Note.
- Siemens Energy seem to be able to deliver large gas-fired power stations to satisfy SSE Thermal.
- Looking at the data sheets for Siemens Energy’s heavy-duty gas-turbines, they can run on a wide range of fuel including biodiesel.
- This document from Siemens Energy describes work to run their gas-turbines on HVO.
- If Keadby 2 can be upgraded to run on hydrogen, I can see no reason why Tarbert and Platin won’t be able to be similarly upgraded in the future.
SSE Thermal seem to be following a similar philosophy to generate lower-carbon electricity at Keadby and in Ireland.
Could We See A Large HVO-Fuelled Power Station In The UK?
I wonder, if we’ll see a large HVO-fuelled power station in the UK?
It appears SSE and Siemens will have the technology and expertise.
I suspect it depends on there being large amounts of HVO available.
Flotation Energy, Vårgrønn Take First Permitting Step For Another Oil & Gas-Powering Floating Wind Farm
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Flotation Energy and Vårgrønn, who recently filed a Marine Licence application for their 500 MW Green Volt floating wind farm in Scotland, have now submitted a Scoping Report for the 1.4 GW Cenos floating offshore wind farm to Marine Scotland.
And this is the first paragraph.
The developers have submitted leasing applications for both Cenos and Green Volt as part of the Crown Estate Scotland’s Innovation and Targeted Oil and Gas (INTOG) leasing round, whose winners are expected to be announced in the second quarter of this year.
Both wind farms have web sites, where you can find more information.
It’s beginning to look like applications for the INTOG leasing round, are going to use quality floating technology and generate very large numbers of megawatts.
In Cerulean Winds Is A Different Type Of Wind Energy Company, I wrote about their plans for a 6 GW proposal for INTOG, spread around four sites in the North Sea.
It looks like we have several companies flexing their technologies to harness the dragons of the Celtic Sea and now it appears, the new giants of the wind are preparing to make a good fist of decarbonising oil and gas in the North Sea.
Utility Completes Testing Of Revolutionary Zero-Electricity Hydrogen Reactor
The title of this post, is the same as that of this article on Hydrogen Central.
These two paragraphs introduce the article.
Utility completes testing of revolutionary zero-electricity hydrogen reactor.
Utility announced at its 3rd annual technology day event, the successful completion of their pilot plant testing program for the H2Gen™ reactor product line. Utility is the only decarbonization technology company pioneering the eXEROTM technology platform optimized for hard to abate industry sectors.
Am I right in thinking, that Utility have developed a way of splitting hydrogen out of hydrocarbons by cleverly exploiting physics and chemistry?
This is the first paragraph on their Learn More page.
The Electroless Coupled Exchange Reduction Oxidation technology platform (eXERO™) capitalizes on both the advantages of electrochemical processes (which yield high product purity without the need for expensive purification steps) and chemical processes (which have comparatively low capital and operating costs, especially avoiding the losses of electricity generation and transmission). The eXERO™ technology platform is achieved by removing the external electrical circuit from an electrolyzer and instead driving the electrolysis reaction with the overpotential (voltage) that exists between different gas compositions. Similar to a conventional solid oxide electrolyzer, oxygen ions are transferred from the cathode to the anode through an oxygen ion conducting electrolyte. However, unlike a conventional electrochemical reactor, electrons are transferred from the anode to the cathode through an electronically conducting phase within the electrolyte, also known as a mixed conducting electrolyte.
In a section on the page, with a heading of Principles, this is said.
The eXERO™ technology platform is based on two streams which are separated by an impermeable electrolyte, and counter-exchange of oxygen ions and electrons. Thus, one of the streams undergoes reduction while the other stream simultaneously undergoes oxidation. Unlike traditional fuel cells or electrolyzers, no current is extracted or delivered to the reactor to drive the process. Rather, an overpotential can be induced by introducing gases of different composition at the anode and cathode the cell. Examples of gases introduced at the anode to induce an overpotential, relative to steam (water) are shown below:
This is interesting. Very interesting!
Belgians To Start Building World’s First Artificial Energy Island Next Year (VIDEO)
The title of this post, is the same as that, of this article on offshoreWIND.biz.
This is the sub-heading.
Belgian offshore construction companies Jan De Nul and DEME, through their consortium TM EDISON, have won the tender for the construction of the Princess Elisabeth Island in their home country and the first artificial energy island in the world.
And this first paragraph outlines the project.
The artificial island, which will be built some 45 kilometres off the Belgian coast and will occupy an area of approximately five hectares above the waterline, will serve as the link between the offshore wind farms in the country’s second, 3.5 GW Princess Elisabeth offshore wind zone and its onshore high-voltage grid.
Initial plans don’t seem to be putting any wind turbines or solar panels on the island.
The most impressive part of the article is the video, which shows how the island will be constructed.
To some people of my age, the construction of the island will seem familiar, as the island will be built in a similar way to the Mulberry harbours of World War II.
A few years ago, I went inside some of the giant Pheonix caissons in The Netherlands, where they were initially used to plug the dykes after the North Sea Flood of 1953. They are now a museum of the floods called the Watersnoodmuseum.
Engineering is repeating itself.
Surveys Completed For Celtic Sea Floating Offshore Wind Projects
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
N-Sea Group has finished a series of benthic and geophysical surveys for Llŷr 1 and Llŷr 2 floating offshore wind projects in the Celtic Sea.
I described the two projects in detail in Two More Floating Wind Projects In The Celtic Sea.
- At least the surveys are complete and it still appears that a commissioning date of 2026/27 is still feasible for these twin 100 MW projects.
- In the original documents, it was stated that there would be six next generation turbines in each wind farm, with a capacity of between 12 and 20 MW.
- There appears to be no decision on the floats or turbine size to be used.
I wouldn’t be surprised to see larger turbines used and the capacity of the farms increased.
