RWE Gets Go-Ahead For 100 MW Electrolyzer For Offshore Wind-to-Hydrogen Project
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
German energy company RWE has secured construction and environmental permits to build a 100 MW electrolyzer in Eemshaven, the Netherlands. The electrolyzer is part of system integration solutions associated with OranjeWind, an offshore wind project RWE is jointly developing with TotalEnergies in the Dutch North Sea.
These first threee paragraphs gove more information.
RWE described the permits as an important step in developing 100 MW of green hydrogen production at Eemshaven which, if built, will contribute to the onshore energy system integration plans associated with the 795 MW OranjeWind offshore wind project.
To remind, in July this year, TotalEnergies entered into an agreement with RWE to acquire a 50 per cent stake in the OranjeWind and said it would use its share of the electricity from the offshore wind project to power 350 MW electrolyzer projects that will produce about 40,000 tonnes of green hydrogen annually.
With the necessary permits in place, RWE stated it will be able to develop a 100 MW electrolyzer on a plot adjacent to the Magnum Power Station in Eemshaven.
I went to Eemshaven in The Train Station At The Northern End Of The Netherlands. The area looks like it will be the centre of the Dutch hydrogen industry.
This post is called The Dutch Plan For Hydrogen. The Dutch appear to want to be big in hydrogen.
A 100 MW offshore electrolyser is a good start.
BOEM Links Up With US Department of Defense On Offshore Wind
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
The US Bureau of Ocean Energy Management (BOEM) and the Department of Defense (DOD) have signed a memorandum of understanding (MoU) to support the coordinated development of offshore wind on the US Outer Continental Shelf (OCS).
These three paragraphs give more details of the agreement.
The agreement calls for DOD and BOEM to find mutual solutions that support renewable energy in a manner compatible with essential military operations.
The MoU also requires the organizations to collaborate early in the offshore wind leasing process and maintain regular communication at all levels.
Additionally, the agreement calls for DOD and BOEM to determine what areas should be deferred from leasing to enable the performance of DOD activities on the OCS.
I feel this is a very sensible agreement, as time progress, I’m sure that the co-operation will lead to several joint projects.
- Support boats ensuring safety, like the deal between Ørsted and the RNLI, that I talked about in Ørsted Evolves Long-Standing Partnership With RNLI,
- Offshore structures like electrolysers and substations could have a secondary use as military training facilities.
- Smaller ships, like minehunters, coastguard cutters and fishery protection vessels could go electric and the wind farms could provide charging facilities.
If the United States Navy are hanging around the wind farms, it might discourage Putin’s friends.
Wind farms and the US military could be good neighbours.
Brendan Owens, who is the Assistant Secretary of Defense for Energy, Installations, and Environment, said this.
We will continue to work with BOEM and our other interagency partners, to find solutions that enable offshore wind development while ensuring long-term compatibility with testing, training, and operations critical to our military readiness.
Other nations with large amounts of continental shelf and ambitions to install large amounts of offshore wind like Australia, Belgium, Canada, Denmark, France, Germany, the Netherlands, Portugal, Spain and the UK could do worse that follow the American strategy.
Iarnród Éireann Looks At Diesel Loco Replacement Options
The title of this post, is the same as that of this article on Railway Gazette.
These three paragraphs introduce the article.
The Stadler Class 99 electro-diesel locomotive for UK operator GB Railfreight was receiving close scrutiny from Iarnród Éireann at InnoTrans in Berlin, with the Irish national operator confirming to Railway Gazette International that it had discussed with the manufacturer how the type might be adapted for operation in Ireland.
Iarnród Éireann Chief Executive Jim Meade told Railway Gazette International ‘we will eventually need to replace our aging diesel fleet with dual-mode locomotives because our freight strategy will take us down that direction after we complete our electrification programme.
‘The replacement for the class 071s and 201s eventually will have to be a bi-mode electric with some form of HVO [renewable diesel fuel] traction in the long term; even the Class 201s are beyond mid-life already.
The Class 99 locomotive is a version of the Stadler Eurodual locomotive, which is described in this Stadler data sheet.
The Wikipedia entry for the Stadler Euro Dual is also informative and lists a dozen different versions of the locomotive, that have been sold to various countries and operators.
This paragraph summarises how the design can handle different gauges and electrical voltages.
The Euro Dual was designed from the onset as a highly modular platform, allowing it to be offered to customers in various different configurations, covering various gauges and voltage systems.
I doubt Stadler would have great difficulty producing an Irish gauge locomotive capable of running on whatever electrification, the Irish erect.
Will The Irish Class 99 Have Enough Power?
The power of the various diesel locomotives are as follows.
- Current Irish Class 071 – 1.68 MW
- Current Irish Class 201 – 2.4 MW
- UK Class 66 – 2.4 MW
- UK Class 99 – 1.79 MW
It would appear that the Class 99 is less powerful than the Irish Class 201 and the UK Class 66, but the Wikipedia entry for the Class 99 says this.
The chief executive of GBRf, John Smith, reports that the Class 99, despite having a less powerful diesel engine than the Class 66, will outperform the Class 66 at low speeds. The greater tractive effort means that the Class 99 on diesel power can deliver more power at the rail than the 66.
But as the Class 99 has 6.17 MW in electric mode, the solution must be to electrify the difficult sections.
I have just looked at the Felixstowe Branch Line, which will be very much Class 99 territory. I am fairly sure, that with some short lengths of electrification on the single-track sections, any performance problems with the Class 99 on the branch could be solved.
Could The Irish Class 99 Use Hydrogen As Secondary Power?
This OpenRailwayMap shows all the railways on the island of Ireland.
Note.
- All railways on the island of Ireland have an Irish gauge of 1.6 m.
- Only the DART in Dublin is electrified with 1,500 VDC overhead.
- There are 2,733 km. of track.
- New lines are still being added and old ones have been reopened in recent years.
- There will surely be pressure for the Irish to decarbonise their railways, both North and South of the Northern Irish border.
- There are no rail connections to another country, except for the link between Northern Ireland and the Republic of Ireland, which is between two similar systems.
- It is unlikely, that there will ever be a rail link between the Irish gauge railways on the island of Ireland and the standard gauge railways of Europe.
Effectively, the island of Ireland has an isolated network of tracks on which they could build a zero-carbon railway system.
- Signalling could be an off-the-shelf digital system.
- Zero-carbon traction power could be trains powered by either electricity and/or hydrogen.
- Both electricity and hydrogen would need substantial amounts of new rolling stock.
- Electricity would require electrification at €1,000,000 per single track kilometer, which could be around €5.5 billion for the electrification alone.
- Electrification would also need many bridges, stations and tunnels to be modified or rebuilt.
- Hydrogen would need a refuelling infrastructure and could go anywhere that diesel can.
- Hydrogen locomotives and trains, would be one-to-one replacements for diesel locomotives and trains.
It would appear that because of their geographic isolation, hydrogen could be an ideal zero-carbon fuel for the railways of Ireland.
In Do Cummins And Stadler Have a Cunning Plan?, I speculated that the electro-diesel Class 99 locomotive could be converted into an electro-hydrogen Class 99 locomotive, as Cummins are building diesel engines that can be converted into hydrogen ones.
Ireland with its unusual network could change to a zero-carbon railway in the following way.
- Purchase a fleet of diesel locomotives and trains that can run on Hydrotreated Vegetable Oil (HVO) and be convertible to hydrogen.
- A version of the Class 99 with or without the electrical gubbins would satisfy the locomotive replacement.
- A version of the tri-mode Stadler FLIRT like a Class 745 train, would satisfy the train replacement.
- All new trains and locomotives would replace the current stock and run on HVO.
- The hydrogen infrastructure would be built.
- The new trains and locomotives would be gradually converted to run on green hydrogen.
Within a few years, the island of Ireland would have a zero-carbon railway.
Advantages Of A Fully-Hydrogen Railway
These are a few advantages.
- One fuel for all trains.
- All trains and locomotives would be one manufacturer.
- No expensive electrification.
- Hydrogen trains and locomotives have a long range.
- No infrastructure modification for gauge clearance.
- Ireland has plenty of onshore and offshore wind for hydrogen.
- Standard fuelling systems are being developed.
- There would be no disruption as the trains changed to HVO and little disruption as they changed to hydrogen.
I believe that there would be a large increase in train usage both from locals and visitors, which can only be good for the Irish economy.
Managing The Project
This could be one of those rare projects that flows well.
- The changeover to hydrogen could involve very little rail infrastructure work.
- The hydrogen filling stations could be more-or-less independent of the rail infrastructure.
- Trains and locomotives could go into service, when they are accepted and the staff have been trained.
- Trains and locomotives would only be converted to hydrogen, as routes are made hydrogen-capable.
- There should be no gauging problems with the new trains and locomotives.
- There is only one train manufacturer.
Hopefully, it will all be delivered on time and on budget.
Centrica And European Energy Sign Agreement On Måde Green Hydrogen Facility
The title of this post, is the same as that of this press release from Centrica.
This is the sub-heading.
Centrica Energy and European Energy have signed a balancing and optimisation agreement for the Måde green hydrogen facility located at Port Esbjerg. Under the agreement, Centrica Energy will manage power production from co-located wind turbines, designating excess power production to green hydrogen production.
These two introductory paragraphs give more details.
Powering the 12MW green hydrogen facility are two wind turbines, part of the Måde Wind Turbine Test Center, developed by European Energy with a total installed capacity of 16MW. The turbines will provide renewable electricity, which is used to produce green hydrogen through electrolysis with demineralised water.
Expected to produce approximately 1,500 tonnes of green hydrogen every year, European Energy has secured an agreement with Port Esbjerg and a world-class industrial gases company for the offtake from the facility. As the production of hydrogen is a heat-intensive process, the excess heat from production will be fed into the local district heating network, demonstrating sector coupling across the electricity, fuel, and heating domains.
These are my thoughts,
Hydrogen Production
The hydrogen production uses a standard electrolysis method, but excess heat will be fed into the local district heating network.
AquaVentus And Denmark
I introduced AquaVentus in this post called AquaVentus.
This video shows the structure of AquaVentus.
I clipped this map from the video.
Note.
- The thick white line running North-West/South-East is the spine of AquaVentus, that delivers hydrogen to Germany.
- There is a link to Esbjerg in Denmark.
- There appears to be an undeveloped link to Norway.
- There appears to be an undeveloped link to Peterhead in Scotland.
- There appears to be a link to just North of the Humber in England.
- Just North of the Humber are the two massive gas storage sites of Aldbrough owned by SSE and Brough owned by Centrica.
- There appear to be small ships sailing up and down the East Coast of the UK. Are these small coastal tankers, that are distributing the hydrogen to where it is needed?
In the last century, the oil industry, built a substantial oil and gas network in the North Sea.
It appears now the Germans are leading the building of a substantial hydrogen network in the North Sea, that will bring the hydrogen they need to their country.
I also suspect that any spare hydrogen produced in Esbjerg can be added to the AquaVentus network.
- Hydrogen could be sent to Brough and Aldbrough in the UK for storage.
- Hydrogen could be sent to any country in the network that needs it.
Countries will pay for the hydrogen they use.
Optimising AquaVentus
AquaVentus is a complex network.
- Hydrogen could be produced offshore in British, Danish, Dutch, English, German, Norwegian, Orcadian, Scottish and Shetland waters.
- Hydrogen could be sent to Brough and Aldbrough in the UK for storage.
- Hydrogen can be sent to Belgium, Denmark, Germany, Norway, The Netherlands and the UK.
A company like Centrica has the expertise and the software to control the various hydrogen flows to the best advantage of hydrogen producers and users.
15+ MW Floating Wind Turbines to Be Tested At Norway’s METCentre
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Three companies have signed contracts with Norway’s Marine Energy Test Centre (METCentre) to test new technology aimed at reducing the costs of floating offshore wind by demonstrating floaters equipped with 15+ MW turbines.
These are the first two paragraphs.
According to Norwegian Offshore Wind, this is the turbine size that will be relevant for future floating offshore wind farms.
The test area is located just a few kilometres away from the Utsira Nord zone, where Norway’s first commercial floating offshore wind farm will be located.
This sounds like the sort of sensible test philosophy, that you’d expect from the Norwegians.
Norway Plans EUR 3 Billion Subsidy For Floating Offshore Wind
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
The Norwegian government has proposed NOK 35 billion (approximately EUR 3 billion) for a support scheme dedicated towards the first commercial floating offshore wind tender within the Vestavind F and Vestavind B areas.
These are the first two paragraphs.
According to the press release, the government is making progress in following up on its ambitious plan to allocate project areas for 30 GW of offshore wind by 2040.
Norway plans to conduct the next tendering round for offshore wind in 2025. After that, the government intends to hold regularly scheduled tendering rounds and state aid competitions leading up to 2040.
The original press release is called A Responsible Approach To Floating Offshore Wind.
Some politicians and green sceptics might not call three billion euros responsible.
I do suspect that Great British Energy will have to deal in this size of numbers to be able to compete with the Norwegians.
We’ll have to work hard to meet our target of 100 GW by 2040.
But at least as the UK’s target is higher, does that mean that the target should be easier. Or do we have more suitable sea?
Principle Power Unveils New Floating Wind Foundations For 15 MW+ Turbines
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Principle Power has expanded its WindFloat portfolio by introducing two new semisubmersible floating wind foundation designs, called WindFloat TC and WindFloat FC, which are said to be optimised for 15 MW+ wind turbines.
A large picture and these two paragraphs introduce the new designs.
According to the company, the new designs are natural evolutions of the existing WindFloat technologies that support a wind turbine located on a column in the centre of the platform.
Designed to complement the existing perimeter column designs WindFloat T and WindFloat F, the new solutions share the same 4th generation design heritage and benefits.
Smart Hull Trim System
The article also mentions a Smart Hull Trim System in this sentence.
Some of these include a Smart Hull Trim system to maximise annual energy production and reduce loads.
I would assume that the Smart Hull Trim System, works very much like the control surfaces of an aeroplane or submarine to keep the craft straight and level.
On the Principle Power web site, the various WindFloats are described as follows.
- WindFloat T – Proven WindFloat® design, suitable for tubular construction.
- WindFloat F – A pontoon-based design suitable for flat panel construction.
- WindFloat TC & FC – Center column design solutions, optimized for 15MW+ turbines with stiff-stiff towers.
From work, I did in the 1970s, with two Cambridge University engineering professors, I reckon that the TC and FC designs will be the best.
Conclusion
Whatever way you look at it, a 15 MW+ floating wind turbine, when you consider they can have capacity factors in excess of 50 %, could be a very powerful electricity generator.
Ireland Joins Forces With EIB For Offshore Wind Port Upgrades
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
The European Investment Bank (EIB) and the Irish Department of Transport have established an advisory cooperation to assess capacity, demand and financing strategies for the development of port infrastructure for offshore wind projects in Irish waters.
These are the first two paragraphs.
Signed by the Irish Minister for the Environment, Climate, Communications and Transport, Eamon Ryan, and EIB Vice President Ioannis, the advisory cooperation aims to evaluate the scale and nature of investment needed to upgrade Irish ports.
The initiative is said to unlock an estimated EUR 30 billion in investment in offshore wind projects in the country which plans to have 20 GW of capacity installed by 2040 and 37 GW by 2050.
It looks to me, that the Republic of Ireland will become a big player in the production of electricity from offshore wind.
I also suspect that Northern Ireland will play its part too!
