UK Consortium Wins GBP 1.5 Million Funding For Offshore Charging Station

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

This is the sub-heading.

A collaboration of UK green technology pioneers has been awarded GBP 1.5 million in funding to install what they say is “the world’s first offshore charging station within a UK wind farm”

These three paragraphs outline the project.

The funding was awarded as part of the Department for Transport and Innovate UK’s GBP 60 million Clean Maritime Demonstration Competition (CMDC).

Project leaders Oasis Marine have partnered with Turbo Power Systems, Verlume, and the Offshore Renewable Energy (ORE) Catapult to deliver the Offshore Charging Station solution.

This smart energy and charging infrastructure could enable fully electric maritime operations within offshore wind farms.

Note.

  1. The offshore charging station would enable many more wind farms to be served by electric or hybrid ships.
  2. Impressive reductions of carbon dioxide emissions are claimed in the article.
  3. The tests will be carried out in Aberdeen Bay.

Given, that it is intended that offshore oil and gas operations are being decarbonised, I can see no reason, why ships working in that industry, can use similar technologies.

Maritime UK Launches Offshore Wind Plan

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

This is the sub-heading.

Maritime UK has unveiled its Offshore Wind Plan which makes a series of recommendations for how the maritime sector, the offshore wind sector, and governments can work together to maximise growth

These are the first three paragraphs and they outline the plan.

The plan outlines how the growth of offshore wind can provide opportunities across the maritime supply chain in sectors like ports, shipbuilding, crewing, and professional services.

Opportunities identified in the Offshore Wind Plan include building vessels in the UK to support developments and further growing UK ports as centres for manufacturing and assembly for offshore developments

Key recommendations and proposals within the plan include: creating quality career pathways for young people; rewarding higher UK supply chain content in offshore wind projects; reforming the planning system to enable green projects to be delivered quicker; and encouraging lenders and investors to finance infrastructure and vessels

Note.

  1. Maritime UK have a web site.
  2. The report seems to be comprehensive.
  3. The report predicts hundreds of ships to build and service wind farms will be needed.

Overall, Maritime UK feel that the maritime sector has a lot to gain from co-operation with the offshore wind sector.

Improved Service Operation Vessels (SOVs)

I don’t see why the large number of Service Operation Vessels (SOVs) needed to serve all the wind farms around our shores, can’t be designed and substantially built in the UK.

In the 1970s, one of Metier Management Systems’ customers for Artemis were the shipbuilders; Austin & Pickersgill, who at the time were building a cargo ship called the SD14, which had been designed to replace the American Liberty ships.

In total 211 SD14s were built in the UK, Greece, Brazil and Argentina.

SD14 stands for Shelter Deck – 14,000 tonnes.

We surely have the technology from companies like BAe Systems, Rolls-Royce and others to design an advanced Service Operation Vessel.

SSE Thermal Outlines Its Vision For The UK’s Net Zero Transition

The title of this post is the same as that of this news item from SSE Thermal.

This is the opening statement.

SSE Thermal, part of SSE plc, is calling on government to turbocharge the delivery of low-carbon technologies to help deliver a net zero power system by 2035.

Two paragraphs then outline what the company is doing.

The low-carbon developer is bringing forward multiple low-carbon projects across the UK. This includes Keadby 3 Carbon Capture Power Station in the Humber – which is being developed in collaboration with Equinor and recently became the first power CCS project in the country to receive planning permission – and Aldbrough Hydrogen Pathfinder, which would unite hydrogen production, storage and power generation in one location by the middle of this decade.

These projects would form part of SSE’s £24bn investment programme in the UK, and in addition to supporting the decarbonisation of industrial heartlands and powering a low-carbon future, they would also help to secure a just transition for workers and communities.

The news item then talks about the future.

Now, SSE Thermal has published ‘A vision for the UK’s net zero transition’ which outlines the need for these low-carbon technologies and the potential of carbon capture and hydrogen in providing flexible back-up to renewables.

It also outlines the steps Government should take to facilitate this:

  • Progress the deployment of carbon capture and storage (CCS) and hydrogen infrastructure in a minimum of four industrial areas by 2030.
  • Support first-of-a-kind carbon capture and storage and hydrogen projects to investment decisions before the end of next year.
  • Increase its ambition for power CCS to 7-9GW by 2030, with regular auctions for Dispatchable Power Agreements.
  • Set out a policy ambition for hydrogen in the power sector and a strategy for delivering at least 8GW of hydrogen-capable power stations by 2030.
  • Accelerate the delivery of business models for hydrogen transport and storage infrastructure, to kickstart the hydrogen economy.

These are my thoughts.

Carbon Capture And Use

There is no mention of Carbon Capture And Use, which in my view, should go hand in hand with Carbon Capture And Storage.

  • Sensible uses for carbon dioxide include.
  • Feeding it to plants like tomatoes, flowers, salad vegetables, soft fruit and herbs in greenhouses.
  • Mineral Carbonation International can convert a dirty carbon dioxide stream into building products like blocks and plasterboard.
  • Deep Branch, which is a spin-out from Nottingham University, can use the carbon dioxide to make animal feed.
  • Companies like CarbonCure add controlled amounts of carbon dioxide to ready-mixed concrete to make better concrete and bury carbon dioxide for ever.

Surely, the more carbon dioxide that can be used, the less that needs to be moved to expensive storage.

Note.

  1. There is a lot of carbon dioxide produced in Lincolnshire, where there are a lot of greenhouses.
  2. At least three of these ideas have been developed by quality research in Universities, in the UK, Australia and Canada.
  3. I believe that in the future more uses for carbon dioxide will be developed.

The Government should do the following.

  • Support research on carbon capture.
  • Support Research on finding more uses for carbon dioxide.

Should there be a disposal premium or tax credit paid to companies, for every tonne of carbon dioxide used in their processes? It might accelerate some innovative ideas!

Can We Increase Power CCS to 7-9GW by 2030?

That figure of 7-9 GW, means that around a GW of CCS must be added to power stations every year.

Consider.

If we develop more ways of using the carbon dioxide, this will at least cut the cost of storage.

Can We Deliver At Least 8GW Of Hydrogen-Capable Power Stations By 2030?

Do SSE Thermal mean that these power stations will always run on hydrogen, or that they are gas-fired power stations, that can run on either natural gas of hydrogen?

In ‘A vision for the UK’s net zero transition’, this is said about the hydrogen power stations.

Using low-carbon hydrogen with zero carbon emissions at point of combustion, or blending hydrogen into existing stations.

So if these power stations were fitted with carbon capture and could run on any blend of fuel composed of hydrogen and/or natural gas, they would satisfy our needs for baseload gas-fired power generation.

Hydrogen Production And Storage

SSE’s vision document says this about Hydrogen Production.

Using excess renewables to create carbon-free hydrogen, alongside other forms of low-carbon hydrogen, which can then be stored and used to provide energy when needed.

SSE’s vision document also says this about Hydrogen Storage.

Converting existing underground salt caverns or creating new purpose-built caverns to store hydrogen and underpin the hydrogen economy.

This page on the SSE Thermal web site is entitled Aldbrough Has Storage, where this is said about storing hydrogen at Aldbrough.

In July 2021, SSE Thermal and Equinor announced plans to develop one of the world’s largest hydrogen storage facilities at the Aldbrough site. The facility could be storing low-carbon hydrogen as early as 2028.

With an initial expected capacity of at least 320GWh, Aldbrough Hydrogen Storage would be significantly larger than any hydrogen storage facility in operation in the world today. The Aldbrough site is ideally located to store the low-carbon hydrogen set to be produced and used in the Humber region.

From my own experience, I know there is a similar salt structure in Cheshire, which has also been used to store gas.

Earlier, I said, that one of the things, that SSE would like the Government to do is.

Progress the deployment of carbon capture and storage (CCS) and hydrogen infrastructure in a minimum of four industrial areas by 2030.

If Cheshire and Humberside are two sites, where are the other two?

Deciding What Fuel To Use

If you take the Humberside site, it can provide electricity to the grid in three ways.

  • Direct from the offshore and onshore wind farms.
  • Using natural gas in the gas-fired power stations.
  • Using hydrogen in the gas-fired power stations.

SSE might even add a battery to give them a fourth source of power.

In the 1970s, I used dynamic programming with Allied Mills to get the flour mix right in their bread, with respect to quality, cost and what flour was available.

Finance For SSE Thermal Plans

The news item says this.

These projects would form part of SSE’s £24bn investment programme in the UK.

£24bn is not the sort of money you can realise solely from profits or in sock drawers or down sofas, but provided the numbers add up, these sorts of sums can be raised from City institutions.

Conclusion

I like SSE Thermal’s plans.

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.

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.

Thoughts On The Wash Barrier

I first learned about tidal power, when I worked for a few months at Frederick Snow and Partners and one of their engineers briefed me about their plans for the Severn Barrage.

That was in about 1973 and it should be remembered, that I didn’t see my first large wind turbine until the last few years of the last century at Swaffham in Norfolk.

I suspect that an engineer revisiting the Severn Barrage would design it differently now.

The Wash Tidal Barrier Corporation

This company is proposing the Wash Barrier, which has a web site.

The name suggests they will generate tidal power.

The home page has a picture of wind turbines, which could be lined up on the barrier.

It also has this introduction to the project.

Sea level rise and climate change are major threats to the Wash coast and fenland environment. Sea level is predicted to rise by at least one metre by 2100 and sea temperatures, already 1°C higher, are increasing by 0.4°C each decade. Storm surges sufficient to overwhelm the Wash coastal defences are becoming ever more likely.

Raising the height of existing coastal defences would not only be prohibitively expensive, but also have a major impact on marginal habitats such as salt marsh, inter-tidal mudflats and sandbanks.

A tidal barrier across the Wash will provide us with the opportunity to manage the tide height and range within the Wash. The Barrier also offers a number of additional benefits – in particular, the generation of a large and reliable amount of green electricity and flood protection for more than 500,000 people, 300,000 hectares of grade 1 agricultural land and billions of pounds’ worth of assets.

The Wash Tidal Barrier Corporation plc is a private company, founded by Cambridgeshire-based entrepreneur Peter Dawe specifically to promote and build a barrier.

The proposed barrier will span the Wash from Hunstanton in Norfolk to just south of Skegness in Lincolnshire, a distance of approximately 18km, with an additional 5km of barrier in Lincolnshire in order to reach high ground.

Following are many of the design considerations we need to assess.

If you click on the Next button, you are led though a few pages that describe the barrier and the issues it raises.

I feel it is a comprehensive outline of what could be done.

It’s also quite old, as it suggests completion in 2012.

These are my thoughts.

Transport Across The Barrier

Some of the world’d barrages across rivers and estuaries have either road or rail links on the top.

Frederick Snow’s original plans for the Severn would have carried a Second Severn Crossing.

In Thoughts On Belgium’s Coastal Tram, I said this.

Along The North Norfolk Coast

This is a route, that could be developed, to ease the traffic problems in the area.

It could connect Kings Lynn and Sheringham stations.

And why shouldn’t it be extended to Skegness?

If the Dutch can put a road across the IJsselmeer, why can’t we put a road across the Wash.

Flood Protection

One of the things I remember from my chat at Frederick Snow and Partners fifty years ago was someone saying, that if you build a barrage, then make sure it sorts out any flooding.

The Wash Barrier web site, says this about flood protection.

The Barrier will provide flood protection for more than 500,000 people, 300,000 hectares of grade 1 agricultural land and billions of pounds’ worth of assets. While building higher significantly adds to the cost, the probability of the Barrier being overwhelmed is greatly reduced.

The promoter of this project would be in deep trouble, if after completion, it didn’t solve the flooding problems, as they said it would.

This article from the Eastern Daily Press, is entitled Norfolk’s Darkest Night: Remembering The 1953 Floods.

No-one wants something like that to happen again.

Electricity Generation

As I said earlier there are possibilities for both wind and tidal power in the project.

As an experienced mathematical modeller, I would be surprised if the power generation and costs of a project like this couldn’t be predicted to a reasonable degree of accuracy by an expert.

Planning Permission

Given the problems that have been associated with building electricity substations and their power cables in Norfolk recently, I would be surprised if planning permission for a Wash Barrage was a piece of cake.

It Could Be One For The Accountants

Once a project like this has been defined, I believe it should be possible to go through the standard financial procedures to see if it was worthwhile to proceed.

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.

  1. Siemens Energy seem to be able to deliver large gas-fired power stations to satisfy SSE Thermal.
  2. Looking at the data sheets for Siemens Energy’s heavy-duty gas-turbines, they can run on a wide range of fuel including biodiesel.
  3. This document from Siemens Energy describes work to run their gas-turbines on HVO.
  4. 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!
