Riveting Television
I’ve just watched an episode of Fred Dibnah’s Made In Britain, which was entitled Mechanics and Riveters.
It was fascinating stuff, but how do you decarbonise an industry like the making of rivets without using hydrogen?
30 MW Offshore Wind Turbines Being Considered For New Project In Sweden
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Freja Offshore, a joint venture between Hexicon and Mainstream Renewable Power, has submitted an application for an offshore wind farm in Sweden that could have an installed capacity of between 2 GW and 2.5 GW and, according to the project’s consultation document, could feature wind turbines of up to 30 MW per unit.
This paragraph, indicates how turbines have grown over the last two decades.
The wind turbines in the future will probably be taller, the rotor diameter larger and the turbines more powerful, the joint venture says in the consultation document, and compares the largest wind turbines launched in 2011, which have a rotor diameter of 164 metres and an installed capacity of 8 MW, with those launched 10 years later, featuring a rotor diameter of 236 metres and an output of 15 MW.
Moving on a few years to 2030 and it doesn’t seem unreasonable that turbine size will double again to 30 MW.
I could see them becoming the standard turbine, providing they aren’t too heavy for the fixed foundations or floats.
It would be an interesting exercise to model the costs of wind farms, as the turbines get bigger.
With North Sea oil and gas, I was told several times, by Artemis users, that as cranes got larger, which allowed bigger lifts, the costs of offshore infrastructure decreased.
Note.
Eviation Still Progressing Even As Alice Remains Earthbound
The title of this post, is the same as that of this article on Flight Global.
The article is a full summary of the status of the Eviation Alice project and very much a must-read.
This article on Skies Magazine, which is entitled Eviation Announces New Order For Up To 50 Alice All-Electric Commuter Aircraft, also gives this information about the order status.
In addition to the latest order from Aerolease, Eviation has also received orders from U.K.-based regional aircraft lessor MONTE (30 aircraft), U.S.-based Cape Air (75 aircraft), U.S.-based Global Crossing Airlines (50 aircraft), Germany-based EVIA AERO (25 aircraft), Australia’s Northern Territory Air Services (20 aircraft), Mexico-based Aerus (30 aircraft), Air New Zealand (up to 23 aircraft), and DHL Express for 12 Alice planes in the eCargo configuration.
Whatver, your view on electric aircraft, the total of 315 orders is impressive for a start-up.
Why Should I Pay For The ULEZ Scrappage Scheme?
The Mayor’s pet anti-pollution project the ULEZ scheme is controversial to say the least.
This article on the BBC is entitled ULEZ: Labour MPs In London Call For ULEZ Scrappage Scheme Review.
So even MPs in his own party don’t agree with the current policy!
Consider.
- I am a non-driver after a stroke ruined my eyesight.
- The only possible benefit, that I might get, is slightly less pollution around where I live.
- But the jury is out on that and the current evidence is dubious, as the Mayor has paid for it to be collected.
- In 2021, the population of London had the chance to remove Sadiq Khan, but decided to re-elect him, despite his ULEZ policy.
- So I have no sympathy for those, who have to rely on a non-compliant car or van to go about their daily business.
- They knew they had to either get a compliant vehicle, pay the £12.50 per day or move to somewhere with a friendlier transport policy.
- If the Mayor wanted to cut pollution in London, he could at least have a hydrogen policy, which allowed large trucks based in London to use this clean fuel.
We have another Mayoral election in 2024!
I shall not be voting for any candidate, who proposes to use London taxpayers’ hard-earned money for a scrappage scheme or who doesn’t have a feasible hydrogen policy.
Train Frequency Focus In North Wales Transport Commission’s Interim Recommendations
The title of this post, is the same as that of this article on Railway Gazette International.
This is the first paragraph.
The North Wales Transport Commission chaired by Lord Burns has published its interim recommendations for the development and delivery of an integrated multi-modal transport system in the region.
The following sections, outline the recommendations for rail services.
Chester Station Improvements
The North Wales Transport Commission (NWTC) supports proposed improvements at Chester station to enable additional services to operate.
This page on Transport for Wales detailed the improvements at Chester station, where this is said.
Transport for Wales is delivering significant improvements to Chester Station. The project primarily focuses on customer improvements within the station, with work to include new branding and signage, a new passenger assist point, cycle stands, roaming mics and hearing loop systems, a new full station CCTV system, toilet refurbishments on the concourse and platforms 4 and 7, a new changing place toilet, customer waiting room upgrade, water refill unit, platform and concourse seating and waste facilities.
New Customer Information Screens will be installed throughout Chester station increasing the train service information available on the platforms and within the station waiting rooms. We’ll also be installing new screens for onward journeys, including bus, and an interactive screen which will be installed on the concourse.
Improvement works in the concourse also include, repurposing of the ticket office to create a new retail unit for the future, a new rental unit, a new customer service desk with ticket selling facilities, additional ticket vending machines, a repositioned gate line with additional standard and wide aisle gates. A new quiet room will also be introduced as a place for customers who require a safe, isolated space whilst waiting for their train.
TfW is working closely with industry partners to minimise disruption during these works for both customers and the local community. Customers are encouraged to plan in extra time to allow for potential disruption during this work. Signage and hoardings will be erected at the station in advance of and throughout, these significant improvement works, and communications will be provided at the station, onboard services and online, to advise of any temporary changes to accommodate the work on site at the station.
Note.
- It looks a serious level of improvement for customers.
- The Chester and Wrexham Line was improved in 2017, with full double-tracking and higher maximum speeds.
- It looks like completion is some time in 2024.
Nothing is said about extra train services.
North Wales Main Line
The NWTC says this about the North Wales Main Line.
On the North Wales Main Line, it says the priority should be service frequency improvements and supporting infrastructure works between Crewe and Llandudno. Improvements to signalling and line capacity from Llandudno to Bangor and Holyhead would require larger scale works, which should be planned so that they are ready to progress as and when funding is available.
I went to Holyhead earlier in the year and more trains would be welcome.
Borderlands Line
The NWTC says this about the Borderlands Line.
Signalling and line capacity improvements are required along the Borderlands Line, the commission believes. A key constraint is the sidings for the Hanson site at Padeswood, where freight trains block the line for up to an hour, and the commission says this needs to be resolved before other work to improve the line can proceed.
There should be investment to reduce journey times and increase service frequencies between Wrexham and Liverpool to significantly increase the attractiveness of the route.
I talked about the freight problem in New Trains Could Be Operating Through Flintshire From May But No Green Light For Two An Hour Service.
This map from OpenRailwayMap shows the track layout at Padeswood site.
I was able to follow a train on Real Time Trains, as it left Padeswood Cement Works.
- It moved to the sidings alongside the Borderlands Line.
- It then joined the Borderlands Line and went Northwards through Buckley, Hawarden, Shotton and Hawarden Bridge stations before stopping in Dee Marsh Sidings.
- The engine then changed ends and brought the train back down the Borderlands Line to Wrexham.
- The train then continued to its destination via Ruabon, Gobowen and Shrewsbury.
This movement doesn’t seem too bad, so has there been some signalling and track improvements?
Shrewsbury And Chester Line
The NWTC says this about the Shrewsbury and Chester Line.
The commission says it has not seen a pressing case for full electrification of the Shrewsbury to Chester line, and the priority should be signalling improvements at Gobowen.
I thought that Shrewsbury and Chester might have been electrified, as it could be used to charge battery-electric going between England and Wales. But it will be some years before Transport for Wales get a battery-electric train strategy together.
On the other hand the two cities are only 42 miles apart, which is in range of battery-electric trains.
Conwy Valley And Cambrian Coast Lines
The NWTC says this about the Conwy Valley Line and the Cambrian Coast Line.
There could be merit in introducing increased frequencies on the Conwy Valley and Cambrian Coast lines during the peak season. Service enhancements and infrastructure improvements such as passing loops may be beneficial, ‘as has happened to similar lines in Devon and Cornwall’, but ’in the immediate future, those communities served by stations along the route should have access to enhanced bus services to reduce dependence on car use’.
This seems like a sensible and non-disruptive plan.
Anglesey Central Railway
The NWTC says this about the Anglesey Central Railway to Amlwch.
NWTC ‘is not persuaded’ that there is a case for opening the line to Amlwch, and says ’more urgent improvements to existing lines and services should take a higher priority’.
The Anglesey Central Railway reopening would appear to be a fairly simple project as the track is mostly already there, so this might be the sort of project, that finds itself moving up the list, if related housing or commercial developments are proposed.
This Google Map shows Amlwch and the surrounding area.
With all the tidal, nuclear and wind energy possibilities in the area, I would never rule out the rail link to Amlwch being restored.
Associated Octel used to have bromine works in Amlwch and more details can be found in this web site.
I’ve worked in chemical works with chlorine, fluorine and bromine and my advice is be very careful with them.
Criccieth And Bangor
NWTC says this about reopening the route between Criccieth and Bangor.
NWTC ‘is not persuaded’ that there is a case for opening the line between Criccieth and Bangor, and says ’more urgent improvements to existing lines and services should take a higher priority’.
This OpenRailwayMap shows the area of the reopening.
Note.
- The orange line going across the top of the map is North Wales Coast Line between Chester in the East and the Port of Holyhead on Anglesey.
- Towards the North-East corner of the map, Bangor station is indicated by the blue lettering.
- The Menai Strait runs between the Welsh mainland and the Island of Anglesey.
- The important town of Caernarfon can be picked out.
- The orange line at the bottom of the map is the Cambrian Line, which connects to Shrewsbury and Aberystwyth.
- This line terminates at Pwllheli on the Lleyn Peninsular in the South-West corner of the map.
A dotted line indicates a disused railway between the Southern coast of the peninsular and Bangor via Caernarfon, which I assume is the railway that has been proposed for reinstatement.
It could be a valuable addition to the railways of North Wales and could help to promote tourism.
Station And Other Improvements On The Borderlands Line
This is said about station and other improvements on the Borderlands Line.
The commission supports a new station at Deeside Industrial Park, and enhancements at Shotton to improve connectivity between the high and low-level platforms.
It says frequency enhancements should be prioritised over new stations, and fleet improvements should facilitate the frequency enhancements. It endorses the proposed use of Merseyrail’s Class 777 battery-electric trainsets on the Borderlands Line.
I feel that the Class 777 trains, which could travel under Liverpool are a shoe-in.
Conclusion
North Wales will be getting the railway it need to promote education, employment, leisure and tourism.
British Five-Year-Olds Up To 7cm Shorter Than Western Peers
The title of this post, is the same as that of this article in The Times.
This is the sub-heading.
Poor diet and health service cuts blamed for ‘pretty startling’ trend
These are the first two paragraphs.
Five-year-olds in Britain are on average up to seven centimetres shorter than their peers in other wealthy nations, in a trend described as “pretty startling”.
A poor national diet has been highlighted as a major culprit in Britain’s fall down international rankings of child height.
I am coeliac and am only 170 cm.
During the pandemic, I did some statistical research on coeliac disease and the covids for my own interest.
I found a peer-reviewed Indian medical paper entitled Coeliac Disease: Can We Avert The Impending Epidemic In India? The author felt that modern high-gluten wheats, were increasing the rate of the disease.
The author also said this about introduction gluten to babies in Sweden.
The time of first exposure to wheat influences the development of celiac disease. In countries such as Finland, Estonia, and Denmark, characterized by low gluten consumption in infancy, celiac disease prevalence is much lower than in Sweden where gluten consumption is high in infancy. A natural experiment occurred in Sweden about two decades ago when national recommendations were made to introduce wheat into the diet after cessation of breast feeding at six months. This change was coupled with increased wheat gluten consumption through infant feeds. Together these measures resulted in a two-fold increase in incidence of celiac disease in Sweden, which was attributed to introduction of wheat into the diet after cessation of breast feeding. In 1996 this recommendation was changed to introduce gluten in gradually increasing amounts while the infant was still being breast fed. This led to a dramatic decrease in celiac disease incidence.
It is interesting to look at heights of five-year-olds given in the Times article for the four countries.
- Denmark – 117.4 – 118.1
- Estonia – 116.9 – 115.7
- Finland – 116.3 – 114.5
- Sweden – 115.1 – 115.1
Note that all heights are in centimetres, with boys first.
As according to the graphs in the article the UK and the US have shown the biggest declines in height, is gluten-rich junk food, the major cause of this decline?
More research needs to be done!
Rolls-Royce Considering Switching From BEV To Hydrogen For Future Models
The title of this post, is the same as that of this article on INSIDEEVs.
This is the sub-heading
The luxury carmaker’s CEO rules out hydrogen combustion, but fuel cells are on the table.
This is the first paragraph.
Rolls-Royce is considering ditching all-electric powertrains in favor of fuel cell technology for its future zero-emissions models once the technology is mature enough and can be scaled to meet its demands, according to Autocar, quoting the luxury car brand’s CEO, Torsten Müller-Ötvös.
As the Rolls-Royce Spectre has a kerb weight of almost three tonnes, I suspect that the handling might make someone like Alec Issigonis, Colin Chapman or Stirling Moss have a good laugh.
But the smaller battery that the fuel cell technology would require, might give a better balance between acceleration, handling and performance.
It would be good fun to model the dynamics of such a heavy car.
I do think though that it is these dynamics, that have suggested a move to hydrogen.
Or Torsten Müller-Ötvös, may have made the statement to find out, what the sort of people, who would buy this car, might think!
New Rolls-Royce Small Engine Set To Begin Tests To Advance Hybrid-Electric Flight
The title of this post, is the same as that of this press release from Rolls-Royce.
These are the first two paragraphs.
Rolls-Royce today announces its new small gas turbine that has been specifically developed to power hybrid-electric flight is set to begin testing. The engine is part of a turbogenerator system that is being developed for the Advanced Air Mobility market. This includes electrical vertical take-off and landing (eVTOL) Aircraft for Urban Air Mobility and Commuter Aircraft applications up to 19 seats.
The turbogenerator system will complement the Rolls-Royce Electrical propulsion portfolio by delivering an on-board power source with scalable power offerings between 500kW and 1200kW enabling extended range on sustainable aviation fuels (SAF) and later, as it becomes available, through hydrogen combustion. This will open up new, longer routes than electric battery powered aircraft can support as of today.
The press release also lays out these design targets.
- Power – 600-1200 kW
- Voltage – 850 Volts
- Power to Weight Ratio – 4 kW/Kg
- Noise – 62 dbA
- Specific Fuel Consumption v in-service products – 15% better
- MTBO – 10,000 cycles
- Length – 1,500 mm.
- Diameter – < 500 mm.
Note.
- At first look, it appears to be small and powerful.
- If they can meet the Power to Weight Ratio of 4 kW/Kg, this would mean that a 1200 kW engine will weigh just 300 Kg.
- The engine has been designed to run on sustainable aviation fuel and hydrogen.
I wouldn’t be surprised to see this engine used in non-aviation applications.
The Shuttle Lift At Whitechapel Station
Whitechapel station is an unusual station on the London Overground/Underground network, as the two Overground tracks are underneath the two Underground tracks.
But then Marc Brunel and his more famous son; Isambard didn’t realise that their Thames Tunnel would eventually be part of London’s circular Overground railway.
The interchange is further complicated, by the Elizabeth Line being dozens of metres below the Overground, so that is connected to the main station bridge concourse by a giant three-barrel escalator.
A single shuttle lift and a set of stairs connect the bridge concourse to the Northbound Overground platform.
Note.
- The route is well used, as passengers have realised it is the fastest way between the Elizabeth Line and the Northbound London Overground.
- Judging by the number of passengers, who exit from the first car of Northbound Overground trains, this route could be a popular one for passengers from South London, who are continuing their journey on the Elizabeth Line.
- I use the route to come home with shopping, I’ve bought along the Elizabeth Line. I can manage the Lizzie Line escalators with two shopping bags and after rising from the depths at Whitechapel, I can take this lift to the first car of a train for Dalston, where there is a lift to the street and a bus to home.
- The lift has only two stops and one button is used to shuttle it, between the stops.
- The lower lift stop is perhaps ten metres from the first car of Northbound Overground train.
- The upper lift stop is perhaps ten metres from the bridge concourse and twenty from the escalator to the Elizabeth Line.
Strangely, the lift and stairs arrangement is more complicated on the Southbound platform of the Overground.
London’s transport network needs more simple shuttle lifts like this.
Grain LNG Launches Market Consultation For Existing Capacity
The title of this post is the same as that of this press release from National Grid.
This is the sub-heading.
Grain LNG, the largest liquefied natural gas (LNG) terminal in Europe, is pleased to announce the launch of a market consultation for the auction of 375 Gwh/d (approx. 9 mtpa) of existing capacity. The initial consultation phase for the Auction of Existing Capacity will commence on 14 June and run until 26 July.
These paragraphs detail what Grain LNG, which is a subsidiary of National Grid are offering.
GLNG has used the positive feedback received from the recent ‘Expression of Interest’ exercise and subsequent market engagement to offer three lots of capacity:
- Each lot will be entitled to 42 berthing slots, 200,000 m3 of storage and 125GWh/d (approx. 3 mtpa) of regasification capacity from as early as January 2029.
- This product is specifically designed for parties who wish to acquire a substantial stake in a major terminal in Northwest Europe, at a reduced cost and with shorter contract lengths when compared to new-build projects.
- As the terminal’s capacity already exists, parties involved will not be subjected to the FID approvals or potential delays that can arise from construction issues commonly associated with new build terminals.
Simon Culkin, Importation Terminal Manager at Grain LNG, said: “We are really pleased with the high level of interest shown by the market at a time of significant geo-political influence on our energy markets. It has allowed us to engage with potential customers and shape our offering to best meet their needs, whilst optimising access to this strategic asset. “
Reading the Wikipedia entry for the Grain LNG Terminal, it looks like it gets used as a handy store for natural gas.
About Phase 1 (2002–05), Wikipedia says this.
The new facilities enabled the Grain terminal to become a base supply to the NTS, with the ability to deliver gas continuously when required. The cost of the Phase 1 project was £130m. A 20-year contract with BP / Sonatrach enabled Grain LNG to import LNG on a long-term basis from July 2005.
About Phase 2 (2005–08), Wikipedia says this.
The development provided an additional five million tonnes of capacity per annum. All this capacity was contracted out from December 2010. Customers included BP, Iberdrola, Sonatrach, Centrica, E.ON and GDF Suez.
Under Current Facilities, Wikipedia says this.
Grain LNG Ltd does not own the LNG or the gas that it handles but charges for gasifying it. Current (2016) users include BP, Centrica (British Gas Trading), Iberdrola (Spain), Sonatrach (Algeria), Engie (France), and Uniper (Germany).
National Grid must be pleased that some customers seem loyal.
I feel that National Grid’s basic plan is to carry on with more of the same.
But will they develop more storage and other facilities on the site.
There are certainly other projects and interconnectors, that make the Isle of Grain and energy hub connecting the UK, Netherlands and Germany.
- In Did I See The UK’s Hydrogen-Powered Future In Hull Today?, I mentioned, that I thought that the Isle of Grain could be a location for an electrolyser and a hydrogen store.
- In EuroLink, Nautilus And Sea Link, I talk about new interconnectors, if which Nautilus might come to the Isle of Grain.
- In UK-German Energy Link Reaches Financial Close, I talk about NeuConnect, which will be an interconnector between the Isle of Grain ans Wilhelmshaven in Germany.
- The Isle of Grain is the landing point for the BritNed undersea power cable between The Netherlands and the UK.
I could also see National Grid building an East Coast interconnector to bring power from the wind farms off the East Coast of England to the Isle of Grain for distribution.
These are major wind farms South of the Humber.
- Dudgeon – 402 MW
- East Anglia 1 – 714 MW
- East Anglia 1 North – 800 MW
- East Anglia 2 – 900 MW
- Galloper – 504 MW – RWE
- Greater Gabbard – 504 MW
- Gunfleet Sands – 174 MW
- Hornsea 1 – 1218 MW
- Hornsea 2 – 1386 MW
- Hornsea 3 – 2852 MW
- Humber Gateway – 219 MW
- Lincs – 270 MW
- London Array – 630 MW
- Lynn and Inner Dowsing – 194 MW
- Race Bank – 580 MW
- Scroby Sands – 60 MW
- Sheringham Shoal – 317 MW
- Triton Knoll – 857 MW – RWE
- Dogger Bank A – 1235 MW
- Dogger Bank B – 1235 MW
- Dogger Bank C – 1218 MW
- Dogger Bank D – 1320 MW
- Dogger Bank South – 3000 MW RWE
- East Anglia 3 – 1372 MW
- Norfolk Boreas – 1396 MW
- Norfolk Vanguard – 1800 MW
- Outer Dowsing – 1500 MW
- North Falls – 504 MW – RWE
- Sheringham Shoal and Dudgeon Extensions – 719 MW
- Five Estuaries – 353 MW – RWE
Note.
- These figures give a total capacity of 28,333 MW.
- Five wind farms marked RWE are owned by that company.
- These five wind farms have a total capacity of 5618 MW.
- Will RWE export, their electricity to Germany through NeuConnect?
I can certainly see National Grid building one of the world’s largest electrolysers and some energy storage on the Isle of Grain, if an East Coast Interconnector is built.
