Polish Hydrogen Locomotive Becomes First In World To Get Approval
The title of this post is the same as that of this article on TVP World.
This is the sub-heading.
The Polish company PESA has received approval to operate its first hydrogen locomotive. As the company boasts, this is the first such approval in the world.
These three paragraphs describe the design and performance of the locomotive.
The approved locomotive is equipped with a zero-emission hydrogen drive. PESA Bydgoszcz SA has been working on such a vehicle for a few recent years.
It is powered by four engines with a power of 180 kW each. Energy for them is provided by two hydrogen cells, with a power of 85 kW, manufactured by Ballard.This is a system that generates electrical voltage through a chemical reaction between hydrogen and oxygen from the atmosphere.
The hydrogen itself is drawn from tanks with a total capacity of 175kg. One refueling is sufficient for 24 hours of continuous operation.
It sounds a very useful locomotive.
Shine On – Centrica Opens Its First UK Solar Farm
The title of this post is the same as that of this press release from Centrica.
These are the bullet points.
- 18MW Codford Solar Farm in Wiltshire is Centrica’s first major solar asset
- Part of plans to build a material portfolio of low carbon assets
- Vodafone supports development with long term Power Purchase Agreement for 50% of the output over 10 years
- Additional renewable power supports the UK government’s ‘green grid’ ambitions
I have some thoughts.
Centrica’s First Major Solar Asset
These two paragraphs from the press release outline the project and indicate where it fits in Centrica’s overall philosophy.
Construction began at the site in Wiltshire in April 2022, after the consent was acquired by Centrica Business Solutions in 2021. Made up of 33,000 panels, the project has a total capacity of 18MW and should produce 19GWh of green electricity every year, enough to power some 4,850 homes.
The deal not only brings additional renewable power provision to the UK grid but supports the UK government’s ambition to focus on home-grown renewable energy to boost long-term energy independence and security.
My only reservation is at 18 MW it isn’t that large and the sun doesn’t always shine in the UK.
Centrica’s Portfolio Of Low Carbon Assets
This paragraph from the press release talks about the portfolio.
In late 2021, Centrica announced ambitions to deliver 900MW of low carbon assets by 2026. The company is currently building battery storage projects at former gas peaking plants at Brigg, Lincolnshire, Knapton, North Yorkshire, and Ostend in Belgium, and has developed a multi GW pipeline of projects.
Note that former gas power plants, usually have a very handy connection to the electricity grid.
900 MW would also rate at around the output of two typical gas-fired power stations.
Vodafone’s Power Purchase Agreement
Big companies like Vodafone seem to be increasingly signing Power Purchase Agreements for their renewable electricity. These must give advantages all round.
- The developer can take the purchaser’s deal to a bank and use it to raise capital for the project.
- The purchaser, in this case Vodafone can say that they use at least some zero-carbon electricity, which must help marketing.
- The bank knows that so long as the sun shines, there will be money flowing to the developer.
- The developer doesn’t have to deal with thousands of customers.
These three paragraphs from the press release outline Vodafone’s deal.
Vodafone will purchase half of the electricity output from the solar farm, helping to support its development and bringing additional renewable power provision to the UK Grid. Combined with agreements already in place, around 47% of the company’s annual energy requirement will come from UK-based renewable power sources by 2025.
The long-term Power Purchase Agreement (PPA) will see approximately 9GWh of green electricity dedicated to Vodafone UK. The remainder will be sold into the national grid through Centrica’s Energy Marketing & Trading business.
The deal is the third PPA signed by Vodafone and Centrica Energy Marketing & Trading over the last year. In May 2022, Vodafone and Centrica announced a long-term PPA with MYTILINEOS S.A for the output from three solar farms in the UK. And, in February 2023, Vodafone committed to take a significant proportion of the output from a further five solar farms in one of the largest corporate solar PPAs to date.
It looks like, when Vodafone’s other solar farms are connected, they will be able to advertise as a zero-carbon company running on renewable electricity.
That sort of green advertising hasn’t hurt Lumo’s trains between London and Edinburgh.
Connecting Codford Solar Farm To The National Grid
This Google Map shows the location of the Codford Solar Farm.
Note.
- The solar panels marked with the red arrow.
- Codford Biogas in the South-West corner of the map.
- The site is surrounded with the fields of a large arable farm, that grows wheat, barley and oilseed rape.
- The site is also shielded by trees.
This second Google Map shows Codford Biogas.
According to their web site, Codford Biogas accept the widest range of food waste in southern England.
The home page describes waste collection, secure disposal and carbon reduction.
Their method of disposal uses anaerobic digestion, which is a complex biological process involving the breakdown of organic matter in the absence of air in large, sealed and insulated vessels with controlled heating and mixing.
The Wikipedia entry for anaerobic digestion describes the process in detail.
On their web site, there is a page, which is entitled What Is AD?, which has an interactive graphic describing the process at Codford.
Main products from the site include.
- 3.6 MW of electricity, which can be fed to the grid.
- Fertiliser, which can be spread directly on the surrounding arable land.
- Waste heat, which will be developed for businesses that need it.
Obviously, the electricity export will need a grid connection, which I suspect will also be used by the new solar farm.
Conclusion
It looks like Centrica have piggy-backed their solar farm on to an existing grid connection.
But it does look like connecting your solar farm to the grid through a power station that can operate continuously, helps to give a more continuous output.
I think we’ll see more of this!
Trains Back On Track After Repairs To Unsafe Nuneham Viaduct
The title of this post, is the same as that of this article on the BBC.
This is the sub-heading.
Rail services between Didcot and Oxford have resumed after a two-month line closure caused by an unsafe viaduct.
These are the first two paragraphs.
Services had been expected to resume on Saturday but the first passenger train ran on the line earlier.
Nuneham Viaduct, which crosses the River Thames near Abingdon, was declared unsafe on 3 April.
It looks like it was a job well done.
Run Larger, Multi-Site Offshore Wind Tenders, French Energy Commission Recommends To Gov’t
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
The French Energy Regulatory Commission (CRE) has recommended that the government conducts larger offshore wind tenders, inviting bids for several sites. This is according to the latest update from CRE, which has now published specifications for the country’s AO5 tender for a floating wind farm in southern Brittany.
Looking at the building of large numbers of wind turbines and their fixed or floating foundations, I am drawn to the conclusion, that it might be better if all were as identical as possible.
I should also note, that we were very successful selling Artemis project management systems in France. Our manager in the country, said it was because all the country’s top managers had been to the same schools and universities and passed the best solutions around themselves.
So perhaps a standard solution appeals to the French psyche?
In the UK, BP are currently designing and planning these fixed foundation wind farms.
- Mona – 1500 MW – 35 m. depth – 30 km. offshore
- Morgan – 1500 MW – 35 m. depth – 30 km. offshore
- Morven – 2907 MW – 65-75 m. depth – 60 km. offshore
Given that Mona and Morgan are in the Irish Sea and Morven is North-East of Aberdeen, I wouldn’t be surprised to find that BP treat these three projects as two separate 3 GW projects, which could share the same turbine design and fixed foundation designs, that were very similar.
I’m sure BP would save money, if they used a similar design philosophy on all three projects.
Stackable Floating Wind Platform Gets DNV Approval
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
DNV has awarded Bassoe Technology an Approval in Principle (AiP) for a 17 MW D-Floater floating wind foundation, designed to withstand extreme 50-year typhoon conditions in the South China Sea.
I wrote about this technology in An Elegant Solution.
This visualisation shows five D-floaters being transported on a ship.
DNV Approval makes it more likely that the design will be deployed in the near future.
Ofgem’s New Net-Zero Mandate To Speed Up ‘Glacial Pace’ Of Realising Grid Connections
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
The UK government will amend the Energy Security Bill to include a statutory net-zero duty for Ofgem, which the British energy regulator will be required to apply and document in decision-making. According to RenewableUK, this will speed up the realisation of grid connections and help unlock at least GBP 15 billion of investment in offshore wind alone by the end of the decade.
I feel, that this must be a good thing.
More Trains To Carmarthen
The last time, I looked at the number of GWR trains to Carmarthen its Wikipedia entry, it was just a couple.
Today, one train per hour (tph) is shown between London Paddington and Swansea, with this supplementary information.
- 7 trains per day continue to Carmarthen, calling at Gowerton (limited), Llanelli, Pembrey & Burry Port, Kidwelly (limited) and Ferryside (limited)
- On Summer Saturdays, 2 trains per day run to Pembroke Dock, calling at all stations between Carmarthen and Pembroke Dock
In Regulator Approves New Grand Union Train Service From Carmarthen To London Paddington, I talked about the plans of Grand Union Trains to run five trains per day (tpd) between London Paddington and Carmarthen.
This would appear to give a total of twelve tpd between London Paddington and Carmarthen.
This page on the Crown Estate web site is entitled Celtic Sea Floating Offshore Wind, where this is said.
The Government has set an ambition to deliver up to 5GW of floating wind by 2030, with rapid expansion anticipated thereafter.
At The Crown Estate, we are committed to helping the UK achieve its net zero ambitions. To support this, we are excited to deliver a new leasing opportunity in the Celtic Sea for the first generation of commercial-scale floating offshore windfarms – unlocking up to 4GW of new clean energy capacity by 2035, kick-starting industry in the region, and providing power to almost four million homes.
We will be inviting full commercial scale projects up to 1GW, which may be developed in a phased or ‘stepping stone’ approach. Recognising the need to develop the UK supply chain and supporting infrastructure for this nascent technology, this approach is deliberately intended to provide opportunities for growth and investment. This will also facilitate the co-ordination of the necessary infrastructure, such as ports and grid connections, all of which are key to the sustainable development of the UK floating wind sector over the long term.
This leasing opportunity will provide the foundation for greater capacity in the future and help establish an exciting new industrial sector for the UK, creating opportunities for significant new investment in jobs, skills and infrastructure for the communities onshore.
It appears to me, that Great Western Railway and Grand Union Trains both believe that there will be large increase in demand for rail travel between London Paddington and Carmarthen and also along the South Wales Coast.
Grand Union Trains are also proposing the building of a new parkway station at Parc Felindre North of Swansea.
But then this area of South Wales and the Celtic Sea, has the four things needed for the development of up to 5 GW of offshore wind; a lot of wind, a large area of empty sea, steel and deep water ports to assemble all the floating wind turbines.
A Zero-Carbon High Speed Railway Between London Paddington And Carmarthen
Consider.
- The Great Western Railway between London Paddington and Carmarthen is 222.5 miles and trains take around three hours and fifty minutes, which is an average speed of 58 mph.
- Between Bristol Parkway and Reading stations, the operating speed is 125 mph.
- In South Wales, the operating speed is generally between 70 and 100 mph.
- Only the 77.4 miles between Cardiff Central and Carmarthen via Swansea is not electrified.
There is probably scope to increase the operating speed using digital signalling and by improving the track.
I would suspect that a time between London Paddington and Carmarthen of under three-and-a-half hours is possible.
The Range Of Battery-Electric Trains
Hitachi have not been specific about the zero-carbon range of their Intercity Tri-Mode Battery Train, which is described in this Hitachi infographic.
In Stadler FLIRT Akku Battery Train Demonstrates 185km Range, I talk about Stadler’s record-braking Battery-electric; Akku, which covered 185 km or 115 miles.
I suspect that Hitachi’s engineers and those at their battery suppliers; Turntide Technology will be ultra-competitive, so I wouldn’t be surprised that the zero-carbon range of the Hitachi train is very competitive to the Stadler FLIRT Akku.
A hundred mile range would allow electric services to be run on these routes.
- Cardiff and Carmarthen – 77.4 miles
- Chippenham and Bristol Temple Meads and return – 48.8 miles
- Chippenham and Bristol Western-super-Mare and return – 86.9 miles
- Swindon and Cheltenham Spa and return – 86.5 miles
- East Coast Main Line and Hull and return – 72.2 miles
- Plymouth and Penzance – 79.5 miles
- Taunton and Newbury – 89.6 miles
- York and Scarborough and return – 84.1 miles
I am fairly sure that Hitachi will aim for at least a hundred mile battery range for their Intercity Tri-Mode Battery Train.
- This would be competitive with other train manufacturers like Stadler and Siemens.
- They would handle a lot of important routes.
- With development they could probably handle Edinburgh and Inverness.
I can’t wait to have a ride.
Fast Train Washer Is Client For Centre Of Rail Excellence
The title of this post, is the same as that of a small article in Rail Magazine.
This is the first paragraph.
The Orange Train Wash (OTW), which aims to clean a train carriage every 22 seconds while using just 1 % of the water of conventional equipment is one of the first commercial clients at the new £400 million Global Centre Of Rail Excellence in South Wales.
Note.
- This is the home page of the company’s web site.
- It has impeccable environmental credentials.
I also think, it has other applications.
Key Mainline Testing Undertaken In Bi Modal Hydrogen Train Project
The title of this post, is the same as that of this article on Rail Technology Magazine.
This is a key paragraph.
In the test, lithium-titanate batteries and the hydrogen fuel cells have been retro-fitted to a CAF Civia Class 463 commuter electric unit train. This then has the ability to create a hybrid powertrain which can run on electrified lines alongside standard lines.
This paragraph describes some of the testing.
The new power system has been integrated into the existing vehicle’s traction system and the current tests on the mainline follow closed track testing and static testing at CAF’s plant in Zaragoza. The mainline testing has taken place across lines in Zaragoza, Madrid and Galicia but the crucial test run for the new unit was on the Zaragoza-Canfranc line where it ran in both electric mode on the electrified line before switching to hybrid mode, combining the fuel from hydrogen fuel cells and batteries where needed.
It sounds like this is a better specified hydrogen-powered train than Alstom’s iLint.
