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!
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.
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.
Close-Up: New Scour Protection Solution That Has Potential To Cut Costs By 70 Pct Inspired By Turtles
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
At the beginning of May, Balmoral presented a scour protection solution that could replace rock dumping and is set to potentially cut costs by up to 70 per cent when compared to this conventional method. In an interview with offshoreWIND.biz, the company revealed that the initial concept behind its new HexDefence system was aimed at a solution for the oil and gas industry but was further developed with the offshore wind industry in mind and that its design was inspired by – turtles.
These first two paragraphs outline HexDefence.
As reported last month, the Scotland-based engineering company introduced HexDefence saying the solution could drastically reduce scour phenomena around fixed offshore wind turbines that cause seabed erosion and a reduction in foundation strength and stiffness.
The structure provides a non-invasive approach to protecting the monopile and the immediate surrounding area and eliminates the need for rock installation which can cost up to 70 per cent more when compared to this new solution, according to Balmoral.
HexDefence has its own section of the Balmoral web site.
In my long career, I have dealt with a lot of fluid flow and I like what Balmoral are doing.
Seaway7 Installs Final Foundation At Seagreen Offshore Wind Farm
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Seaway7 has installed the final wind turbine foundation on Seagreen Offshore Wind Farm, off the coast of Angus, Scotland, concluding the 18-month installation campaign.
Note.
- As 114 foundations have been installed in eighteen months or just over six installations in a month.
- According to Deepest Ever Fixed-Bottom Wind Turbine Foundation Stands Offshore Scotland, each foundation weighs two thousand tonnes.
- Some are also the deepest ever turbine foundations with a depth or is that height of nearly sixty metres.
- The Seagreen web site, says that phase 1 will be complete in the second quarter of this year.
- The first phase will generate 1075 MW.
We should raise a few cheers for the companies involved.
St. Pancras To Heathrow By Elizabeth Line
I ate breakfast in Le Pain Quotidien in St.Pancras station this morning and afterwards I took the Elizabeth Line to Heathrow.
I took Thameslink for one stop to Farringdon station and got a Elizabeth Line train direct to Terminal 2 and 3 at the Airport.
Note.
- The train I took was going to Gravesend. I suspect it was because of engineering work.
- An empty train passed through, whilst I waited. I’ve never seen that before on Thameslink in St. Pancras station.
- I travelled in the front of the Thameslink train for the one stop.
- The change at Farringdon station was very quick, as it was just down in the lift and the Heathrow train was waiting.
These are some notes on a fast change using the lifts between Southbound Thameslink and the Elizabeth Line at Farringdon station.
- Get the first lift of the two that arrives, if like me, you can use escalators.
- If it goes up, walk across the station at street level and get the two serial escalators down to the Elizabeth Line.
- If it goes down, take the lift to the Elizabeth Line.
If you can’t manage escalators, you have to wait for a lift going down.
I have some observations.
Meeting And Greeting At St. Pancras Station
From my position in Le Pain Quotidien, I was able to watch passengers leaving and arriving at the Eurostar terminal opposite.
There were quite a few people, who were meeting and greeting others.
In Effects Of The ULEZ In West London, I said this about meeting and greeting at Heathrow.
But as it now so easy to get to the Airport using the Elizabeth Line will more people use the new line to meet and greet and say goodbye to loved ones or business associates. Since the Elizabeth Line opened, I’ve met a couple of friends at Heathrow, who were passing through.
Will the Elizabeth Line increase the number of trips to the airport, by making meeting and greeting easier?
If it does, then it will put more pressure on the services to Heathrow Airport.
Seats In St. Pancras Thameslink Station
These pictures show some of the large number of seats in St. Pancras Thameslink Station.
Should there be more seats along the platform at stations on the Elizabeth Line, where passengers change trains?
My Train To The Airport Was Crowded
Ten in the morning on a Sunday, is not the time I’d expect to be busy, but I estimated it was about ninety percent full, judging by the few empty seats.
There Were Eight Trains Per Hour (tph) To And From Heathrow
From Real Time Trains, it looks like the following trains were running.
- Elizabeth Line – Abbey Wood and Terminal Four – 2 tph
- Elizabeth Line – Abbey Wood and Terminal Five – 2 tph
- Heathrow Express – Paddington and Terminal Five – 4 tph
My train to the Airport had been going to Terminal Four.
Is eight tph the maximum frequency, that can use the tunnel to the Airport?
Is The Elizabeth Line Diverting Passengers From Heathrow Express?
When I returned from the Airport, my Elizabeth Line train left about ten minutes after a Heathrow Express train.
- The Heathrow Express train wasn’t very full.
- The Elizabeth Line train was very full.
- Passengers got out at all stations.
- I got out at Tottenham Court Road.
It will be interesting to see the Heathrow Express passenger figures.
Which Is The Best Elizabeth Line Station For A Marks and Spencer?
Because their gluten-free food is so much better than other shops, this is important to me.
- There are larger stores at Ealing Broadway, Tottenham Court Road (West), Liverpool Street (West), Stratford and Ilford.
- There are food only stores at Heathrow, Paddington, Bond Street and Liverpool Street (East).
Today, I used the large store by the Western entrance at Tottenham Court Road station.
But, if you want to avoid walking, Stratford is probably the easiest.
Cheesecake Energy Collects £9.4m Government Funding
The title of this post, is the same as that of this article on UKTN.
These two paragraphs outline how they will use the grant.
Cheesecake Energy will use the government funding to install its energy storage solution as a microgrid in Colchester to help with local grid limitations.
University of Nottingham spinout Cheesecake Energy’s installation will collect energy made by a solar farm with a capacity of 8MW and a central heat pump that supplies a district heat pump network.
Cheesecake Energy have been on my list of possible successful energy storage systems for some time and this sounds like a very neat application for energy storage.
Cheesecake Energy bill themselves on their web site as The World’s Greenest Battery, which is a big claim to make.
This outline of their technology is given on their Our Technology page.
Cheesecake Energy’s eTanker energy storage system is a stationary, medium to long-duration energy storage solution which delivers cheap, reliable, efficient energy storage in a modular, containerised package.
The technology stores energy in the form of heat and pressurised air, re-tasking ex-service truck engines to become zero-emission electrical power-conversion machines for putting energy into storage and recovering it from storage. The resulting system does not use diesel or any fuel. It is safe, straightforward to operate, has a lifetime of up to 25 years and can deliver turnaround efficiencies of around 70%.
I like the idea of using recycled truck engines at the heart of the system.
Conclusion
The World’s Greenest Battery could be right!
Farewell! Mary Quant!
This is a true story I heard, when I worked for ICI.
Do you remember those horrible drip-dry shirts, that men used to wear in the 1960s?
I suspect I took some to University, as my mother felt I could wash them.
Did you know that Mary Quant was partly responsible for their demise?
Mathematics tell us, that a pair of tights need a lot more nylon, than a pair of stockings.
As Mary Quant got a lot more ladies wearing tights to go with mini-skirts, there was a shortage of nylon.
ICI, who made much of the UK’s nylon, decided unilaterally to divert nylon from men’s shirts to ladies’ hosiery.
Bye bye! Nylon shirts!
RIP Dame Mary
Deepest Ever Fixed-Bottom Wind Turbine Foundation Stands Offshore Scotland
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
The world’s deepest fixed-bottom wind turbine foundation has been installed at what will be Scotland’s largest offshore wind farm – Seagreen – off the coast of Angus.
This is the first paragraph.
On Friday, 7 April, the jacket foundation was transported to the project site on a barge operated by the main contractor, Seaway 7, where it was met by the Saipem 7000 – the semisubmersible crane vessel which is used to lift each of the 2,000-tonne turbine foundations into place.
It is obviously, a very worthwhile engineering achievement.
But two thousand tonnes of steel and a giant crane to lift it into place seems a bit of an overkill to me.
I believe that there must be a better method.
I feel that Entrion Wind’s idea of a FRP monopole, which I talked about in Entrion Wind Wins ScotWind Feasibility Deal For Its 100-Metre Depth Foundation Tech, could be a better bet.
