Chinese Offshore Wind Foundation Manufacturer Inks MoU With Scotland’s Ardersier Port
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Dajin Heavy Industry and Haventus, the owner and developer of Ardersier Port in Scotland, have signed a Memorandum of Understanding (MoU) to explore combining Dajin’s manufacturing and transport capability with Ardersier’s port infrastructure to support both fixed-bottom and floating wind projects in the UK and across Europe.
These two paragraphs add more details.
Dajin and Haventus will also work together to identify potential new commercial opportunities and how Ardersier Port could provide a site for storage, marshalling, assembly and transportation of offshore wind components to the offshore wind foundation manufacturer.
According to Haventus, Ardersier Port’s extensive quayside land, deep-water access and a high-voltage power connection can support the manufacturing, fabrication, assembly and storage of large-scale structures for offshore wind and other energy-related projects.
These are my thoughts.
Where Is Ardesier?
This Google Map shows the location of the Port of Ardesier in relation to Inverness, the Orkneys and Shetlands, and Norway.
The Port of Ardesier would appear to be ideally placed to bring in business for the partnership.
This Google Map shows more detail around Haventus – Ardesier Port.
Note.
- Haventus appears to be located close to Inverness Airport, which has a railway station on the Inverness and Aberdeen Line.
- Inverness is on the Moray Firth.
Are Haventus A British Company?
I asked Google AI the question in the title of this section and received this answer.
Yes, Haventus is a British company.
It is registered in the UK with its corporate headquarters in London, and its primary operations focus on redeveloping the Ardersier Port in the Scottish Highlands to support offshore wind energy.
Company Details
Registration: Registered in England and Wales (Haventus Limited).Head Office: London, United Kingdom.
Project: Transforming the former fabrication yard at Ardersier Port near Inverness, Scotland, into an energy transition facility for offshore wind.
Key Backing: Funded by British institutions like the UK Infrastructure Bank and the Scottish National Investment Bank, alongside major private equity investment from US-based Quantum Capital Group.
Could The Port Of Ardersier Have A Rail Connection?
This OpenRailwayMap shows the Port of Ardersier, the Aberdeen and Inverness Line and Inverness Airport.
Note.
- The heavy black track is the Aberdeen and Inverness Line.
- The Port of Ardersier is above it in the middle of the map.
- Inverness Airport is marked by the blue arrow.
There seems to be a lot of space in the area.
Could A Steel Mini-Mill Be Built In The Area?
Consider.
- Dajin Heavy Industry could need a lot of steel.
- A steel mini-mill would need a lot of energy.
- The UK has a lot of scrap steel, that could be of good enough quality to make the steel gubbins needed for offshore wind components.
- Scrap could be brought in by sea or rail.
- That part of Scotland has lots of offshore wind power.
- Three pumped storage hydro systems are being built in the Scottish Highlands to store electricity.
- Workers could be brought in by train from as far as Aberdeen.
The Port of Ardersier could be an ideal place for a steel mini-mill.
How Many Acres Do You need for a Small Steel From Scrap Mill?
I asked Google AI the question in the title of this section and received this answer.
A small scrap-based steel mini-mill requires roughly 5 to 20 acres of land for basic production, casting, and rolling units.
If you include a dedicated on-site scrap yard and heavy inventory storage buffers, the requirement expands closer to 25 to 50+ acres.
Core Space Breakdown
Melt Shop & Electric Arc Furnace (EAF): 2 to 4 acres for the core melting furnace, ladle metallurgy furnace, and pollution control equipment.
Casting & Rolling Mill: 2 to 5 acres for continuous casting (billets or blooms) and the hot re-rolling lines.
Scrap Yard & Raw Materials: 5 to 20 acres depending on how much local scrap inventory you need to stockpile.
Finished Goods & Logistics: 3 to 10 acres for cooling beds, product staging, truck loading docks, and internal roadways.
From this crude analysis with Google AI, I believe that there is enough space to put a small steel mill in the area.
Ideas Borrowed From Failures During The Years Of North Sea Oil and Gas
I suspect there are a few of these, which might be possible to develop at Ardersier.
Conclusion
The Port of Ardersier has lots of possibilities,
Man In Seat 61: My Nail-Biting Journey To Orkney By Train And Ferry
The title of this post is the same as that of this article in The Times.
This is the heading.
Now the Caledonian Sleeper connects the Midlands to Scotland in style. Mark Smith travels to the UK’s most northerly rail station and beyond
These are the first two paragraphs.
In January the Caledonian Sleeper added Birmingham to its route from London to Scotland — its first new stop in 30 years. With a ticket for one of the first departures and a bucket-list desire to see the historic naval anchorage that is Scapa Flow, I would ride the sleeper to Inverness, take Scotland’s scenic Far North Line to Britain’s northernmost station and then sail across the Pentland Firth to Stromness. I could leave my Buckinghamshire home in the evening and reach Orkney 24 hours later without setting foot on a plane. It sounded like a plan.
The Highland sleeper (which travels to the Highlands; there is also a Lowland sleeper that travels to Edinburgh and Glasgow) rolled into Birmingham International at 10.42pm on the dot. I was greeted at the door by a steward with a friendly Scottish accent and my room key. He jotted down my breakfast reservation and I headed for room 4 in car L. The Cal Sleeper is rightly proud of its Scottish-made mattresses and fluffy duvets and I drifted off to sleep in my cosy berth to the sound of steel wheel on steel rail.
I feel adding a Birmingham International stop is a masterstroke, as it gives so many travel options.
- You could of course still join in London.
- I might go to Birmingham on Chiltern, as I prefer the trains to Avanti West Coast.
- There are lots of shows and exhibitions in Birmingham.
- If you had a relative in Scotland and you lived in the far South-East of England and Wales, half of the journey would be in a comfortable bed.
- Birmingham International has regular connections to Aberystwyth, Bournemouth, Pwllheli, Shrewsbury and Wrexham General.
- Some journeys might be easier with a change between plane and sleeper train at Birmingham International.
The list is endless and will grow as travellers have other ideas.
More imagination needs to be added to train journeys.
My first thoughts are.
There needs to be a Lumo-style service between Birmingham and Scotland and a sleeper between Birmingham and Penzance.
MoU Signed To Develop Scottish Highlands As Offshore Wind And Renewables Hub
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
The Inverness and Cromarty Firth Green Freeport (ICFGF) has signed a Memorandum of Understanding (MoU) with the UK and Scottish governments and The Highland Council, creating a formal framework for cooperation in developing the Highlands as a major international hub for the offshore wind and renewable energy sector
This is the first paragraph.
The agreement is said to unlock GBP 25 million (approximately EUR 29 million) in funding from the UK government, which ICFGF plans to use to support the delivery of significant infrastructure projects and its partner ports.
These are some points from the rest of the article.
- Inverness and Cromarty Firth Green Freeport aims to bring up to 11,300 jobs to the Highlands.
- Significant investments we’ve already include the Sumitomo subsea cable plant at Nigg and the Haventus energy transition facility at Ardersier.
- Over the next 25 years, ICFGF is expected to attract over GBP 6.5 billion of investment.
- The Green Freeport includes three tax sites: Cromarty Firth, which includes Port of Nigg, Port of Cromarty Firth, and Highland Deephaven.
- Ardersier Energy Transition Facility has secured a GBP 100 million joint credit facility to create nationally significant infrastructure for industrial-scale deployment of fixed and floating offshore wind.
- It has placed contracts with more than 110 local firms as part of the development.
These investments will setup the long-term future of Inverness and the Highlands of Scotland.
The Inverness and Cromarty Firth Green Freeport (ICFGF) has this web site, with these messages on the home page.
Europe’s strategic hub for renewable energy
Transforming the Highland economy and delivering national energy security
Conclusion
This area will become one of the most vibrant places in Europe.
Haventus, Sarens PSG Unveil ‘On-Land to Launch’ Floating Wind Solution
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
UK companies Haventus and Sarens PSG have developed a low-cost solution for the integration and launch of floating offshore wind turbines.
These two introductory paragraphs add more details.
Haventus said that it is working to enable offshore wind project developers to acquire fully assembled floating bases and turbines at Ardersier, Scotland, as well as providing dry storage which does not require complex licensing.
A heavy-lift solution will enable safe on-land integration and launch to the harbour of fully integrated floating offshore wind turbines.
Note.
- Haventus introduce themselves on their web site, as an energy transition facilities provider, offering pivotal infrastructure for the offshore wind industry. The first facility, they are developing is the Port of Ardesier in the North of Scotland, to the North-East of Inverness.
- Sarens PSG introduce themselves on their web site, as specialists in turnkey heavy lifting and transportation solutions for offshore wind component load-in, marshalling, assembly, deployment, and integration.
It looks to me that the two companies are ideal partners to put together flotillas of large floating wind turbines.
These two paragraphs seem to describe the objectives of the partnership.
This should shorten supply chains through single-site sourcing of key components and remove the operational, safety, logistical, and engineering complexity that comes with storage and integration activities in the marine environment.
The companies also said that the solution can also drive down the costs and accelerate floating offshore wind deployment by simplifying transport and installation requirements and remove the obstacles of weather and design life variables that must be considered with ‘wet’ storage and integration.
I was always told as a young engineer to define your objectives first, as you might find this helps with the design and costs of the project.
I do wonder sometimes, if the objectives of High Speed Two smelt too much of a project designed by lots of parties, who all had different objectives.
The Location Of The Port Of Ardesier
This Google Map shows the location of the Port of Ardesier in relation to Inverness, the Orkneys and Shetlands, and Norway.
The Port of Ardesier would appear to be ideally placed to bring in business for the partnership.
SSE Announces Construction Of Aberarder Wind Farm
The title of this post, is the same as that as an advert on my online edition of The Times.
Click the advert and you get this page, with the title of this post.
This is the sub-heading.
Aberarder secured 15-year CfD in UK Allocation Round 5
These three paragraphs give more details of the wind farm.
SSE has taken a final investment decision to proceed with Aberarder Wind Farm in the Scottish Highlands, in a circa £100m investment boost for its onshore wind portfolio.
Construction of the 12 turbine, 50MW wind farm, which is wholly owned by SSE Renewables, will begin before the end of the year with completion scheduled for the end of 2026. The Aberarder project was successful in September 2023 in the UK’s fifth Contract for Difference (CfD) Allocation round, securing a 15-year contract for low-carbon power generation.
Located at Strathnairn near Inverness, on a natural plateau at an average of 700m above sea level, the Aberarder project site sits directly adjacent to the operational 94MW Dunmaglass Wind Farm, which is jointly owned by SSE Renewables and Greencoat UK Wind.
It would appear that a £100m investment in the Scottish Highlands will get you a fully-operational 50 MW wind farm.
These are my observations and thoughts.
SSE’s Project Overview Of Aberarder Wind Farm
These four paragraphs are SSE’s project overview from this page on the SSE Renewables web site.
The Aberarder Wind Farm project is located in Strathnairn near Inverness, on a natural plateau at an average of 700m above sea level. It will sit directly adjacent to the operational 94MW Dunmaglass Wind Farm, which is jointly owned by SSE Renewables and Greencoat UK Wind.
The project was developed by RES and consented by The Highland Council in April 2017. The consent allows for the construction of a 12-turbine onshore wind farm, with each turbine having a maximum tip height of up to 130m and is expected to have an export capacity of 49.9MW. SSE Renewables reached an agreement with RES to acquire Aberarder in October 2022.
In September 2023 Aberarder was successful in the UK’s fifth Contract for Difference (CfD) Allocation Round and was awarded a 15-year contract for low carbon power generation. SSE took a final investment decision to proceed with Aberarder Wind Farm, in a circa £100m investment in May 2024, construction is scheduled to begin before the end of 2024 with completion scheduled for the end of 2026.
Our focus is now on building strong and meaningful relationships with the local community surrounding the Aberarder Wind Farm. As a responsible developer and operator, we are looking forward to working closely with the community in surrounding area to fully realise the benefits of this exciting project.
Construction has now started and it would appear that in two years, the twelve-turbine wind farm will be producing power.
SSE’s Description Of Dunmaglass Wind Farm
These four paragraphs are SSE’s description from this page on the SSE Renewables web site.
Located to the south east of Inverness, on a natural plateau at an average of 700m above sea level, Dunmaglass is SSE’s highest wind farm to be constructed.
SSE acquired the project from RES in May 2013 and initial enabling works began in the summer of 2013 which included the upgrading of 11km of tracks and the construction of two timber deck bridges.
Highland contractor RJ McLeod was awarded the £16m main civil works contract in summer 2014.
Dunmaglass became fully operational in 2017.
This paragraph also illustrates the challeges of the It looks like the construction of the larger Dunmaglass wind farm.
The height at which Dunmaglass is located presented its challenges during construction and the winter months brought high winds and plenty of snow. The site was fully completed and handed to the operations team in 2017.
Surprisingly, the legendary Highland midges didn’t get a mention.
The Sale Of 49.9 % Of Dunmaglass Wind Farm To Greencoat UK Wind
This sub-heading outlines the sale.
In February 2019, SSE sold 49.9% of Dunmaglass to Greencoat UK Wind PLC as part of a deal in which Greencoat acquired a 49.9% stake in both Dunmaglass and the nearby Stronelairg wind farm.
This paragraph gives more details of the sale.
In February 2019, SSE signed agreements for the sale of 49.9% of Dunmaglass wind farm to Greencoat UK Wind Plc (“UKW”). This sale was part of a £635m deal in which Greencoat acquired a 49.9% stake in both Stronelairg and Dunmaglass wind farms. The stakes equate to 160.6MW (megawatts) of capacity, with an average valuation for the two wind farms of around £4m per MW. This valuation demonstrates SSE’s ability develop quality, low carbon assets and infrastructure vital to the GB energy market.
The interesting figure is that SSE was paid £4m per MW for the interest of 160.6 MW, that they sold.
Aberarder wind farm is a 50 MW wind farm and it appears that it will cost £100 million to build.
If after a couple of years of operation, the wind farm is worth £4 million per MW, then SSE have doubled their money.
Does this illustrate, why the professionals like SSE and Greencoat UK Wind invest in wind farms?
- SSE would have taken the risk, that they could build the wind farm.
- SSE have the engineering skillsto do an excellent job.
- Greencoat UK Wind are buying into a producing asset, with a known cash flow.
SSE also get more money to build more wind farms.
Where Are Aberarder And Dunmaglass?
This Google Map shows the site of Aberarder wind farm with respect to Inverness.
Note.
- Inverness is at the top of the map on the waters of the Solway Firth.
- Aberarder wind farm is marked by the red arrow.
- Aberarder is a hamlet to the North-West of the wind farm.
- Drumnaglass is a shooting estate to the North-West of the wind farm.
- Loch Duntelchaig is the main reservoir for Inverness.
This second Google Map shows the Drumnaglass wind farm.
Note.
- Drumnaglass wind farm has 33 turbines and a capacity of 94.05 MW.
- There is a track network of 11 km. linking all the turbines.
- A good proportion of the turbines can be picked out on the map.
It would appear that Aberarder wind farm will lie to the South-East of this wind farm.
Aberarder Wind Farm To Fort Augustus
In Cloiche Onshore Wind Farm, I talked about the 130.5 MW Cloiche wind farm and its future construction to the East of Fort Augustus and Stronelairg wind farm.
This Google Map shows the position of Aberarder wind farm with respect to Ford Augustus.
Note.
- Loch Ness runs across the North-West corner of the map.
- Fort Augustus and Stronelairg wind farm, are at the Southern end of the loch.
- The red arrow shows Aberarder wind farm.
- Foyers pumped hydro is on the Eastern bank of Loch Ness, at about the same latitude as the Aberarder wind farm.
- The lake at the bottom of the map, to the South-East of Ford Augustus, is the Glendoe Reservoir, that powers the Glendoe hydroelectric scheme.
There are certainly, a lot of SSE-owned and/or SSE-controlled assets in the area and I wouldn’t be surprised, if SSE integrated them more closely, or added a few more wind farms.
Why Are SSE Advertising The Start Of Construction?
SSE have been advertising for some time on The Times web site.
As they are not a retail energy company anymore, as they sold their retail business to OVO, the advertising, is probably about spreading a good corporate message and getting their strategy broadcast.
Redevelopment Of Scottish Port Begins As Owner Secures GBP 400 Million For Offshore Wind Upgrade
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Haventus, the owner of the Ardersier Port in the Moray Firth, Scotland, has taken a final investment decision and kicked off construction work on redeveloping the port to serve both fixed-bottom and floating offshore wind projects. The revamped port is expected to open in the second half of 2025.
These are the first two paragraphs.
This month, Haventus was granted a GBP 100 million (approximately 117 million) joint credit facility from the Scottish National Investment Bank and UK Infrastructure Bank with GBP 50 million (approx. EUR 58.5 million) investment from each.
This follows a GBP 300 million (approx. 351 million) investment commitment by the energy investment firm Quantum Capital Group in 2023 when Haventus began the redevelopment of Ardersier Port.
This page on the Haventus web site, gives more details of the Port of Ardersier.
Included are.
- Access channel width – 160 m.
- Access channel depth – 12.4 m.
- Landside area – 350 acres.
- 420m main quay.
- 80 m Ro/Ro capable berth.
- People-friendly midges
- Green Freeport tax site designation
- More space is available if required.
There is also an informative video.
Haventus say they are delivering a world-leading energy transition facility. I can go along with that!
These are my thoughts.
The Location Of The Port of Ardersier
This Google Map shows the location of the Port of Ardersier.
Note.
- The large expanse of water in the middle of the map is Moray Firth.
- The blue arrow at the bottom of the map indicates Inverness Airport.
- Inverness Airport, has a railway station on the Aberdeen and Inverness Line.
- The village of Ardersier is on the the Eastern bank of the Moray Firth
- The Port of Ardersier is in the North-East corner of the map.
The city of Inverness, with a population of around 48,000, is a few miles South-West of the South-West corner of the map.
Which Windfarms Will Be Built And Serviced From The Port Of Ardersier?
This map shows the various ScotWind leases, around the North of Scotland.
The numbers are Scotwind’s lease number in their documents.
These are the Scotwind wind farms to the North-East of Scotland, that could reasonably be assumed to be built and served from the Port of Ardersier.
- 7 – DEME Concessions Wind – 200 km² – 1.0 GW – Floating
- 8 – Falck Renewables Wind – 256 km² – 1.0 GW – Floating
- 9 – Ocean Winds – 429 km² – 1.0 GW – Fixed
- 10 – Falck Renewables Wind – 134 km² – 0.5 GW – Floating
- 11 – Scottish Power Renewables – 684 km² – 3.0 GW – Floating
- 12 – BayWa r.e. UK – 330 km² – 1.0 GW – Floating
These are the Scotwind wind farms to the North-West of Scotland, that could reasonably be assumed to be built and served from the Port of Ardersier.
- 13 – Offshore Wind Power – 657 km² – 2.0 GW – Fixed or Floating
- 14 – Northland Power – 390 km² – 1.5 GW – Floating
- 15 – Magnora – 103 km² – 0.5 GW – Floating
- 16 – Northland Power – 161 km² – 0.8 GW – Floating
These ten wind farms add up to 12.3 GW.
Transport
Consider.
- Obviously, heavy components will be brought in by sea, using the Ro/Ro capable berth or using a crane to unload a barge.
- Personnel will be able to fly in for the day.
- Will some visitors rom London use the Caledonian Sleeper to and from Inverness station to get a full day on site and a good night’s sleep, whilst travelling.
But I do see a problem with local traffic to and from the site.
Hydrogen Buses
This page on the Sizewell C web site, discusses how they will use hydrogen buses.
I could see the Port of Ardersier taking a leaf out of Sizewell C’s book and run hydrogen buses to Inverness, Inverness Airport and other nearby towns.
The North of Scotland certainly won’t be short of green hydrogen to power the buses.
Hydrogen
Conclusion
If you thought that the only useful wind-driven thing to come out of Scotland was bagpipes, you had better think again.
The Port of Ardersier will be the factory and operation and maintenance port for one of the largest offshore wind industries in the world.
Highland Council Forges Green Hydrogen Pact
The title of this post, is the same as that of this article on renews.biz.
These are the first two paragraphs.
Getech subsidiary H2 Green has signed a memorandum of understanding (MoU) with the Highland Council in Scotland aimed at creating a regional network of green hydrogen hubs across the Scottish Highlands.
Under the terms of the MoU, H2 Green and the Highland Council will produce a regional plan to develop a network of green hydrogen hubs at optimal locations across the region.
The first hub appears to be in Inverness, as I wrote in Hydrogen Hub Plan Will Cut Transport Sector Emissions In The Highlands.
But that is only the start.
- Green hydrogen will be used in transport in the Highlands.
- By-products like oxygen and heat will be distributed.
- Delivery of Highland decarbonisation will be planned.
- SGN Commercial Services will service large-volume customers.
- Agreements are in place for Eversholt Rail to deploy their hydrogen-powered trains on the Far North and West Highland Lines of Scotland.
This statement from Jonathan Copus of Getech, sums up the objectives of the hydrogen project.
These activities combined with the Highland Council initiative are set to establish the Highlands as the leading UK-centre for decarbonisation and innovation; they will also support job creation, deliver energy security and provide a sustainable path for the region’s net zero transition.
I believe that a similar approach could be taken in other parts of the UK. Cornwall, East Anglia, Lincolnshire, much of Wales and the Borderlands between England and Scotland come to mind.
Each region will probably, decarbonise slightly differently and each will develop more and more innovative ways to use the hydrogen.
Conclusion
Hydrogen will play a large part in the decarbonisation of the UK.
Hydrogen Hub Plan Will Cut Transport Sector Emissions In The Highlands
The total of this post, is the same as that of this article on the Ross-Shire Journal.
This is the introduction to the article.
The site of one of the Highland capital’s most distinctive industrial landmarks is set to take on new life and a new role, helping decarbonise transport in the region.
The former SGN gas holder site on Harbour Road, Inverness, has been identified by H2 Green as an ideal location for its new green hydrogen production, storage, and distribution facility.
H2 Green, which is part of the Getech Group, signed a deal with gas network operator SGN for use of the site, which lies between Inverness’s rail depot and industrial area.
This Google Map shows the centre of Inverness.
Note.
- Inverness station in the South West corner of the map.
- Inverness bus station is nearby.
- Harbour Road runs across the top of the map.
It looks to me that the round structure in the North East corner is the former SGN gas holder.
These are my thoughts.
The Size Of The Electrolyser
At eight tonnes of hydrogen per day, the proposed electrolyser would be almost as big as the Herne Bay Electrolyser, which creates ten tonnes of hydrogen per day.
Could The Gas Holder Be Used To Store Hydrogen?
As the gas holder was probably built for town gas, which contains a lot of hydrogen, I suspect it could be refurbished to hold hydrogen.
Oxygen Production
The article also says this about oxygen production.
The hub could also provide zero-carbon heat and medical-grade oxygen for hospitals, aquaculture and water treatment works in the area.
Could it be that oxygen is at a premium in the Highlands, so H2 Green are filling a need?
At the height of the pandemic, when hospitals had an oxygen shortage, I asked ITM Power, if they could produce medical grade oxygen, as a by-product of creating hydrogen. They replied in the affirmative.
Conclusion
It looks to me, that H2 Green have a well-thought out plan for hydrogen in The Highlands.
Thoughts On Batteries On A Hitachi Intercity Tri-Mode Battery Train
This Hitachi infographic describes a Hitachi Intercity Tri-Mode Battery Train.
Hitachi are creating the first of these battery trains, by replacing one of the diesel power-packs in a Class 802 train with a battery-pack from Hyperdrive Innovation of Sunderland.
This press release from Hitachi is entitled Hitachi And Eversholt Rail To Develop GWR Intercity Battery Hybrid Train – Offering Fuel Savings Of More Than 20%, gives a few more details.
The Class 802 train has the following characteristics.
- Five cars.
- Three diesel power-packs, each with a power output of 700 kW.
- 125 mph top speed on electricity.
- I believe all intermediate cars are wired for diesel power-packs, so can all intermediate cars have a battery?
In How Much Power Is Needed To Run A Train At 125 Or 100 mph?, I estimated that the trains need the following amounts of energy to keep them at a constant speed.
- Class 801 train – 125 mph 3.42 kWh per vehicle mile
- Class 801 train – 100 mph 2.19 kWh per vehicle mile
The figures are my best estimates.
The Wikipedia entry for the Class 800 train, also gives the weight of the diesel power-pack and all its related gubbins.
The axle load of the train is given as 15 tonnes, but for a car without a diesel engine it is given as 13 tonnes.
As there are four axles to a car, I can deduce that the diesel power-pack and the gubbins, weigh around eight tonnes.
How much power would a one tonne battery hold?
This page on the Clean Energy institute at the University of Washington is entitled Lithium-Ion Battery.
This is a sentence from the page.
Compared to the other high-quality rechargeable battery technologies (nickel-cadmium or nickel-metal-hydride), Li-ion batteries have a number of advantages. They have one of the highest energy densities of any battery technology today (100-265 Wh/kg or 250-670 Wh/L).
Using these figures, a one-tonne battery would be between 100 and 265 kWh in capacity, depending on the energy density.
As it is likely that if the diesel power-pack replacement would probably leave things like fuel tanks and radiators behind, so that the diesel engines could be reinstalled, I would expect that a battery of around four tonnes would be fitted.
On the basis of the University of Washington’s figures a 400 kWh battery pack would certainly be feasible.
Using. the energy use at 100 mph of 2.19 kWh per vehicle mile, I can get the following ranges for different battery sizes.
- 400 kWh battery – 36.53 miles
- 500 kWh battery – 45.67 miles
- 600 kWh battery – 54.80 miles
- 800 kWh battery – 73.06 miles
As Lincoln and Newark are just 16.6 miles apart, it looks to me that a 500 or 600 kWh battery could be a good choice for that route, as it would leave enough hotel power for the turnround.
It should also handle shorter routes like these.
- Newbury and Bedwyn – 13.3 miles.
- Didcot and Oxford – 10.3 miles
- Newark and Lincoln – 16.6 miles
- Leeds and Harrogate – 18.3 miles
- Northallerton and Middlesbrough – 20 miles
- Hull and Temple Hirst Junction and Hull – 36.1 miles
Some routes like Temple Hirst Junction and Hull would need charging at the destination.
The Range Of A Five Car Train With Three Batteries
Suppose a Hitachi Intercity Tri-Mode Battery Train had three battery-packs and no diesel engines.
- It would be based on Hitachi Intercity Tri-Mode Battery Train technology.
- It would have two driver cars without batteries.
- It would have three intermediate cars with 600 kWh batteries.
- It would have 1800 kWh in the batteries.
- The train would be optimised for 100 mph running.
- My estimate says it would need 2.19 kWh per vehicle mile to cruise at 100 mph.
It could have a range of up to 164 miles.
If the batteries were only 500 kWh, the range would be 137 miles.
The Ultimate Battery Train
I think it would be possible to put together a nine car battery-electric train with a long range.
- It would be based based on Hitachi Intercity Tri-Mode Battery Train technology, which would be applied to a Class 800 or Class 802 train.
- It would have two driver cars without batteries.
- It would have seven intermediate cars with 600 kWh batteries.
- It would have a total battery capacity of 4200 kWh.
- The train would be optimised for 100 mph running.
- My estimate in How Much Power Is Needed To Run A Train At 125 Or 100 mph?, said it would need 2.19 kWh per vehicle mile to cruise at 100 mph.
That would give a range of over 200 miles.
If the batteries were only 500 kWh, the range would be 178 miles.
Aberdeen, Inverness, Penzance and Swansea here we come.
Can Hitachi Increase The Range Further?
There are various ways that the range can be improved.
- More electrically-efficient on-board systems like air-conditioning.
- A more aerodynamic nose.
- Regenerative braking to the batteries.
- Batteries with a higher energy density.
- Better driver assistance software.
Note.
- Hitachi have already announced that the Class 810 trains for East Midlands Railway will have a new nose profile.
- Batteries are improving all the time.
I wouldn’t be surprised to see a ten percent improvement in range by 2030.
Conclusion
I was surprised at some of the results of my estimates.
But I do feel that Hitachi trains with 500-600 kWh batteries could bring a revolution to train travel in the UK.
Edinburgh And Aberdeen
Consider.
- The gap in the electrification is 130 miles between Edinburgh Haymarket and Aberdeen.
- There could be an intermediate charging station at Dundee.
- Charging would be needed at Aberdeen.
I think Hitachi could design a train for this route.
Edinburgh And Inverness
Consider.
- The gap in the electrification is 146 miles between Stirling and Inverness.
- This could be shortened by 33 miles, if there were electrification between Stirling and Perth.
- Charging would be needed at Inverness.
I think Hitachi could design a train for this route.
Roger Ford’s Cunning Plan
In the February 2020 of Modern Railways, there is an article called LNER Procurement, which has been written by Roger Ford.
It is Roger’s reply to an article in the December 2020 Edition of Modern Railways, which was entitled LNER Seeks 10 More Bi-Modes.
He starts by describing the requirement and then says this.
Would any fleet engineer in his or her right mind want to add a unique sub-fleet of 10 high speed trains to an existing successful fleet, even if they were hydrogen-electric tri-modes from the respected Kim Chong t’ae Electric Locomotive Works?
In my analysis of the December 2020 article, I wrote this post with the same name, where I said this, under a heading of More Azumas?
Surely, It would require a very innovative train at perhaps a rock-bottom price from another manufacturer, for LNER to not acquire extra Azumas.
So it would appear that Roger and myself are vaguely in agreement on the subject of more Azumas.
The last section of the article has a title of Cunning.
Roger puts forward, the view that the procurement process, as well as being compatible with EU law, could be a warning to Hitachi, to make sure that LNER get a good deal.
It certainly could be, and I remember a similar maneuver by ICI around 1970.
The company was buying a lot of expensive IBM 360 computers.
ICI needed a new computer to do scientific calculations at their Central Instrument Research Establishment (CIRL) at Pangbourne in Berkshire.
- English Electric had just released a clone of an IBM 360 and were keen to sell it to ICI.
- As it would do everything that ICI wanted, they bought one.
- It worked well and did everything that CIRL wanted at a cheaper price.
IBM’s reaction was supposedly quick and dramatic. The salesman who dealt with ICI, was immediately fired!
But as ICI had about a dozen large IBM computers, there wasn’t much they could do to one of the most important and largest UK companies.
IBM also made sure, that ICI got their next computer at a good price.
I’m with Roger that all the shenanigans are a warning to Hitachi.
Roger finishes the article with these two paragraphs.
A genuine bluff would have been to seek bids for the long-term deployment of remanufactured IC225s. Which in these straitened times could still turn out to be a more viable option.
I rather fancy the idea of a hydrogen-electric Class 91. Owner Eversholt Rail might even have played along on the understanding that it funded the inevitable hybrid Azumas.
Note that IC225s are InterCity 225 trains.
- The 31 trains, were built for British Rail in the 1980s.
- They are hauled by a 4.83 MW Class 91 locomotive, which is usually at the Northern end of the train.
- Nine Mark 4 coaches and a driving van trailer complete the train.
- As with the Hitachi Azumas (Class 800 and Class 801 trains), they are capable of operating at 140 mph on lines where digital in-cab ERTMS signalling has been installed.
I just wonder, if a Class 91 locomotive could be to the world’s first 140 mph hydrogen-electric locomotive.
Consider the following.
Dynamics
The wheels, bogies and traction system were designed by British Rail Engineering Ltd, who were the masters of dynamics. This is a sentence from the locomotive’s Wikipedia entry.
Unusually, the motors are body mounted and drive bogie-mounted gearboxes via cardan shafts. This reduces the unsprung mass and hence track wear at high speeds.
That is a rather unique layout. But it obviously works, as otherwise these locomotives would have been scrapped decades ago.
I believe the quality dynamics are because BREL owned a PACE 231R for a start, which was an analogue computer, that was good enough for NASA to use two computers like this to calculate how to put a man on the moon.
London and Edinburgh is a slightly shorter distance, run at a somewhat slower speed.
Space
This picture shows a Class 91 locomotive.
What is in the space in the rear end of the nearly twenty metre-long locomotive?
This sentence from the Wikipedia entry for the locomotive gives a clue.
The locomotive also features an underslung transformer, so that the body is relatively empty compared to contemporary electric locomotives.
It also states that much of the layout came from the APT-P, which was a version of the tilting Advanced Passenger Train.
Would the space be large enough for a tank of hydrogen and some form of generator that used the hydrogen as fuel?
It should be noted that one version of the APT used a gas-turbine engine, so was the locomotive designed for future use as a bi-mode?
Fuel Cells
I’ve ignored fuel cells, as to get the amount of power needed, the fuel cells could be too large for the locomotive.
Class 91 Locomotive Performance
The performance of a Class 91 locomotive is as follows.
- Power output – 4.83 MW
- Operating speed – 140 mph
- Record Speed – 161 mph
Not bad for a 1980s locomotive.
Required Performance Using Hydrogen Fuel
If the locomotives were only needed to use hydrogen to the North of the electrification from London, the locomotive would need to be able to haul a rake of coaches twice on the following routes.
- Aberdeen and Edinburgh Haymarket – 130 miles
- Inverness and Stirling – 146 miles
A range of three hundred miles would be sufficient.
The locomotive would need refuelling at Aberdeen and Inverness.
The operating speed of both routes is nowhere near 140 mph and I suspect that a maximum speed of 100 mph on hydrogen, pulling or pushing a full-size train, would probably be sufficient.
When you consider that a nine-car Class 800 train has five 560 kW diesel engines, that give a total power of 2.8 MW, can carry 611 passengers and an InterCity 225 can only carry 535, I don’t think that the power required under hydrogen will be as high as that needed under electricity.
Rolls-Royce
Rolls-Royce have developed a 2.5 MW generator, that is the size of a beer keg. I wrote about it in Our Sustainability Journey.
Could one of these incredibly-powerful generators provide enough power to speed an InterCity 225 train, through the Highlands of Scotland to Aberdeen and Inverness, at speeds of up to 100 mph.
I would give it a high chance of being a possible dream.
Application Of Modern Technology
I do wonder, if the locomotive’s cardan shaft drive could be improved by modern technology.
These pictures show Joseph Bazalgette’s magnificent Abbey Mills Pumping station in East London.
A few years ago, Thames Water had a problem. Under the pumping station are Victorian centrifugal pumps that pump raw sewage to Beckton works for treatment. These are connected to 1930s electric motors in Dalek-like structures on the ground floor, using heavy steel shafts. The motors are controlled from the control panel in the first image.
The shafts were showing signs of their age and needed replacement.
So Thames Water turned to the experts in high-power transmission at high speed – Formula One.
The pumps are now connected to the electric motors, using high-strength, lower-weight carbon-fibre shafts.
Could this and other modern technology be used to update the cardan shafts and other parts of these locomotives?
Could The Locomotives Use Regenerative Braking To Batteries?
I’ll start by calculating the kinetic energy of a full InterCity 225 train.
- The Class 91 locomotive weighs 81.5 tonnes
- Nine Mark 4 coaches weigh a total of 378 tonnes
- A driving van trailer weighs 43.7 tonnes.
- This gives a total weight of 503.2 tonnes.
Assuming that each of the 535 passengers, weighs 90 Kg with babies, baggage, bikes and buggies, this gives a passenger weight of 48.15 tonnes or a total train weight of 551.35 tonnes.
Using Omni’s Kinetic Energy Calculator, gives the following values at different speeds.
- 100 mph – 153 kWh
- 125 mph – 239 kWh
- 140 mph – 300 kWh
I think, that a 300 kWh battery could be fitted into the back of the locomotive, along with the generator and the fuel tank.
With new traction motors, that could handle regenerative braking, this would improve the energy efficiency of the trains.
Sustainable Aviation Fuel
Sustainable aviation fuel produced by companies like Altalto would surely be an alternative to hydrogen.
- It has been tested by many aerospace companies in large numbers of gas turbines.
- As it has similar properties to standard aviation fuel, the handling rules are well-known.
When produced from something like household waste, by Altalto, sustainable aviation fuel is carbon-neutral and landfill-negative.
ERTMS Signalling And Other Upgrades
Full ERTMS digital signalling will needed to be fitted to the trains to enable 140 mph running.
Conclusion
I believe it is possible to convert a Class 91 locomotive into a hydrogen-electric locomotive with the following specification.
- 4.83 MW power on electricity.
- 140 mph on electrification
- 2.5 MW on hydrogen power.
- 100 mph on hydrogen
- Regenerative braking to battery.
If it were easier to use sustainable aviation fuel, that may be a viable alternative to hydrogen, as it is easier to handle.
