The Anonymous Widower

Are Rolls-Royce Converting The World To Sussainable Fuels?

Rolls-Royce are certainly up to something.

  • Versions of all their diesel and aero engines appear to be able to or will be able to run on hydrogen, SAF, HVO and other exotic zero or low-carbon fuels.
  • They are replacing the engines on the USAF B 52s with new American-built Rolls-Royce engines, that can run on hydrogen.
  • They are working with easyJet on zero-carbon engines.
  • They are developing the UltraFan, which promises to be the most frugal turbofan engine ever. Will all long-distance wide-bodies end up Rolls-Royce powered?
  • They have developed a frugal engine for business jets that can run on any fuel.
  • Rolls-Royce have also developed a 2.5 MW electric generator based on the engine of a Super Hercules. This level of power is what you need for a railway locomotive.
  • Are they building a retrofit for all the diesel-electric railway locomotives of the world, which runs on hydrogen?

Some of these developments could be moving from diesel, jet-fuel and SAF to hydrogen. Others will just reduce the amount of fuel needed.

I just can’t get the image of an iconic B 52, with RR on the side of the engines out of my mind.

But all of these developments seem to have one aim in mind. – To reduce the amount of aircraft and other large vehicles that have to run on standard jet fuel, diesel, SAF or HVO.

This will mean that long-distance air travel, which will be the most difficult to decarbonise will be able to use SAF and other exotic fuels made from renewable sources.

UK Wind Risks ‘Exponentially Rising’ Curtailment Without Energy Storage

The title of this post, is the same as that of this article on Recharge.

This is the sub-heading.

UK liquid battery pioneer Highview Power is working with renewable energy giant Orsted on plan to store excess power from its Hornsea offshore wind projects

This is the introductory paragraph.

The UK wind sector faces “exponentially” increasing curtailment of assets without a rapid rollout of energy storage, says the chief of liquid battery pioneer Highview Power, which is working with Orsted on a project to store excess offshore wind power.

The article also states that according to Octopus Energy, this cost could have been as high as a billion pounds last year.

In Grid Powers Up With One Of Europe’s Biggest Battery Storage Sites, I described how Ørsted were planning to build a large BESS near the Swardeston substation in Norfolk, where the Hornsea 3 wind farm will connect to the grid.

Have Ørsted  decided to put a Highview Power battery on the Swardeston site, as it can be a bigger battery, as Highview Power talk about 200MW/2.5GWh capacity batteries on the projects page of the web site?

Highview also say this about co-operation with Ørsted on that page.

Highview Power and Ørsted’s joint study shows that the co-location of LAES with Ørsted’s offshore wind offers a step forward in reducing wind curtailment, and helping to move to a more flexible, resilient zero carbon grid.

The words are accompanied by pictures of a smart gas storage site, which shows four of the largest tanks, that might be used to store LNG.

In Could A Highview Power CRYOBattery Use A LNG Tank For Liquid Air Storage?, I estimated that one of the largest LNG tanks could hold about a GWh of energy.

So Highview Power’s visualisation  on their project page would be a 4 GWh battery.

ZeroAvia Receives FAA G-1 For 600kW Electric Propulsion System

The title of this post, is the same as that of this press release from ZeroAvia.

This is the sub-heading.

Issue paper confirms basis of certification and provides clear pathway to certification of the company’s first commercial product

These are two introductory paragraphs.

ZeroAvia today announced that it has reached consensus on the Certification Basis relating to its 600kW electric propulsion system (EPS) with the Federal Aviation Administration (FAA), having received a G-1 Issue Paper (stage 2) and formally confirmed agreement with its contents.

The G-1 represents a key milestone on the journey towards final certification of the company’s EPS with the U.S. regulator, and also on its path to certifying its first full hydrogen-electric powertrain (of which the EPS is a core system) with the UK Civil Aviation Authority. The issue paper designates the applicable airworthiness regulations specific for ZeroAvia’s EPS, allowing the company to validate its design requirements.

Zero-carbon aviation just got a little bit closer, as when it is certified, the 600 KW electric propulsion system (EPS) will be able to be retrofitted to aircraft like the Cessna Caravan.

This is a Cessna Grand Caravan, that I flew in on holiday in Kenya.

I can see a lot of zero-carbon Caravans flying around the tropics on hydrogen generated by a nifty piece of hydrogen gubbins powered by the sun.

Especially, as over three thousand have been built.

I’ve Just Come Across Avnos

I feel we should take into account any possibilities of second use of oil or gas structures, that once held hydrocarbons.

An article in a magazine called Carbon Herald pointed me to a company called Avnos, who are developing Direct Air Capture of carbon dioxide out of the atmosphere. If systems like that of Avnos do work, we may need somewhere to put the carbon dioxide.

 

Centrica are storing the hydrogen in the Rough gas field, which was previously used for storing natural gas and now some depleted gas fields are being used to store captured carbon dioxide.

 

On the subject of carbon capture, Avnos do it differently, in that for every tonne of CO2, they capture from the air, they capture five tonnes of distilled water. And they do it without using any heat.

This is their web site.

This is their mission statement on the front page of the web site. There is also a video.

Carbon Negative. Water Positive

Avnos is commercializing the most advanced technology in the Direct Air Capture of CO2

Our proprietary Hybrid Direct Air Capture (HDAC) solution inverts the water paradigm in DAC, producing water, eliminating heat consumption and reducing costs compared to other forms of DAC.

It sounds too good to be true!

But I have experience of the positive financial results of fluid dynamics in this area.

Thirty years ago, two guys approached me with an idea for an aerosol valve that used nitrogen as a propellant.

At the time, I lived in the house, where Osborne Reynolds, the great Victorian fluid dynamicist of Reynold’s number fame had been brought up.

The guys succeeded and the device was sold on to J & J.

They were then asked to develop a metered dose inhaler for asthma drugs, which is now sold as Respimat, which is sold by Boehringer Ingelheim.

Afterwards, I researched Reynolds at Manchester University, where he was the first Professor of Engineering and I found that he had done some marvelous things with fluids. He was a true genius and undergraduates are still taught on his Victorian apparatus.

I suspect that Avnos may have been exploring in the same area and are using another of Reynold’s useful properties.

Paddington And Minehead By Train

Two projects announced in the last six months may make this a possibility.

  • FirstGroup’s Paddington and Paignton Service
  • The West Somerset Tidal Lagoon

Neither project has the full permissions it needs, but if Lumo do stop at Taunnton and the West Somerset Tidal Lagoon is built, if could open up an interesting possibility.

In Thoughts On Lumo’s Proposed Paddington And Paignton Service, I stated that a train could take two hours between  Paddington and Taunton, if it went for a fast non-stop run to Bath Spar station.

In MP Pushes For Tidal Lagoon In Bristol Channel, I said this.

I believe that for the lagoon project to be complete, the West Somerset Railway needs to be turned into a fully-operational branch line between Minehead and Taunton to improve access for residents, visitors and workers to Minehead and other places in West Somerset.

Surely, with a quick change of train, passengers could be in Minehead thirty minutes after arriving at Taunton.

In recent years several new branch lines have open in the UK and been given time to attract new passengers.

  • The Borders Railway to Tweedbank
  • Merseyrail to Headbolt Lane
  • The Northumberland Line to Ashington
  • ScotRail to Leven.
  • The Dartmouth Line to Okehampton

None appear to be in any danger of being closed.

I very much feel, that if the West Somerset Railway, ran a full service between Minehead and Taunton, it would follow the same pattern.

British Buses For British Bottoms

Occasionally, I catch the 153 bus, as it goes between the Leon, where I often go for breakfast, and the William Harvey Heart Centre, where I volunteer as a lab-rat.

Lately, I’ve noticed that the route is being run by new Wrightbus GB Kite single-decker battery-electric buses.

This morning I had a ride.

Note.

  1. The buses are battery-electric.
  2. This page is the bus’s home page.
  3. This bus is the short 10.2 metre long version.
  4. It was certainly a well-built, smooth-riding and comfortable bus, that was approved by my sensitive British bottom.

This Press Release from Wrightbus is entitled Wrightbus Sets Sights On Further European Expansion After Hydrogen Buses Land In Germany.

This is the sub-heading.

Leading zero-emission bus pioneer Wrightbus has announced plans for further expansion into Europe following the arrival of a landmark hydrogen bus order into Germany.

These are the first three paragraphs.

All of the 31 buses for operator Regionalverkehr Köln Gmbh (RVK) are now in situ – the first ever Wrightbus vehicles on European soil – with testing underway before the fleet goes into service across the Cologne region.

Named the fastest-growing bus manufacturer in Europe, Wrightbus has enjoyed a remarkable year. Alongside further hydrogen bus deals for Saarbahn, Vestische, Cottbus and West Verkehr, and the opening of a new European service centre in Bruhl, Wrightbus is also hiring staff to supply buses to France and Benelux.

In October, it also signed a landmark deal worth up to half-a-billion pounds to supply more than 1,000 buses to operator Go-Ahead over the next three years – 90 per cent of which will be zero-emission.

The press release says that deals are possible in France and Benelux.

MP Pushes For Tidal Lagoon In Bristol Channel

The title of this post, is the same as that of this article on the BBC.

This is the sub-heading.

Building a tidal lagoon in the Bristol Channel could provide clean energy for 120 years, an MP has said.

These three paragraphs give more details.

The proposed West Somerset Lagoon, which would cost £10bn to build, would run nine miles (14km) from Minehead to Watchet in Somerset.

Its lifespan would be twice that of a nuclear power plant, said Tiverton and Minehead MP Rachel Gilmour.

Mrs Gilmour said she will soon be discussing the proposal with ministers. If the project is pursued, it could be up and running by 2038 – bringing jobs and financial benefits to the area.

The project already has a web site, with this mission statement.

The West Somerset Tidal Lagoon is a proposed Tidal Range power scheme, that aims to harness the energy of the tides to provide zero carbon renewable energy. It is strategically located on the southern coast of the Bristol Channel Basin between Minehead and Watchet to take advantage of the world’s second highest tidal range and will become the UK’s largest sustainable energy project.

This map from OpenRailwayMap shows the coast between Minehead and Watchet.

Note.

  1. Minehead station is indicated by the blue arrow in the North-West of the map.
  2. Watchet station is indicated by the blue lettering on the Eastern edge of the map.
  3. The West Somerset Railway links the two stations and connects them to the Bristol and Exeter Line at Norton Fitzwarren station.

It looks like the sea wall of the lagoon will curve between Minehead and Watchet.

The West Somerset Railway

This OpenRailwayMap shows the whole West Somerset Railway.

Note.

  1. Minehead station is in the North-West corner of the map.
  2. Norton Fitzwarren station is indicated by the blue arrow in the South-East corner of the map, where the West Somerset Railway joins the main line between Exeter and Bristol.
  3. Taunton station on the main line with trains all over the country is a few miles to the East of Norton Fitzwarren station.

I believe that for the lagoon project to be completed, the West Somerset Railway needs to be turned into a fully-operational branch line from Taunton to improve access for residents, visitors and workers to Minehead and other places in West Somerset.

Large projects like these need large numbers of workers to be completed.

Less disruption to local residents and businesses is caused if a park and ride site is set up. Sizewell C is setting up two from the nearby East Suffolk Line, using hydrogen-powered buses.

Sizewell C also intends to bring in heavy equipment and construction materials by rail from Ipswich and Lowestoft.

The West Somerset Tidal Lagoon could use the railway to bring in heavy loads.

If the West Somerset Railway is going to be used to ease the construction of the lagoon , then this should be properly to connected to Taunton first.

The Lady On The Train

One of the most amazing people, I’ve ever met was a New York State Supreme Court Judge. It is wrong to guess a lady’s edge, but she was about my age; late seventies, black, well-dressed and sat down next to me in Second Class with the biggest smile on her face on the train between Cambridge and London.

She was at a legal conference of senior judges from all over the world at Cambridge University and was going exploring in London.

The reason for the smile was extraordinary. When she went to the ticket counter, she was surprised that the Pakistani-as-she-described him ticket guy asked for her age. He then asked, if she would be doing any other travelling in the UK and when she said yes, he sold her a Senior Railcard as well. She had found it such a surreal experience, that would never have happened in the States that she was still laughing, when the sat down.

She could of course have been not just a New York State Supreme Court Judge, but a full United States Supreme Court Judge and I’d misheard, although I doubt she would have been one of Trump’s picks last time around.

I do hope that when Trump finds himself in the United States Supreme Court as he inevitably will, that she is there to give her verdict.

Thoughts On The Washington National Air Tragedy

I flew light aircraft for over twenty years as a hobby and to get about on business. I flew mainly in the UK, but flew for perhaps fifty to a hundred hours in Australia, France, Ireland, Italy and the United States. I flew planes on to islands like the Scillies in the UK, the Lido in Venice and the Barrier Reef in Australia. It was great fun and I enjoyed it immensely.

 

I had a friend, who had been an RAF Air Traffic Controller, who would be horrified at Trump’s remarks on diversity, as although he was white, he had been born in Tobago and had many ATC colleagues who were not white.

 

Flying around the world, most ATC personnel, try to smooth you on your way, even in France and Italy. But American ATC seems to work under unnecessary pressure because they allow planes to where British, French and Australian ATC wouldn’t.

 

I was told in the 1970s, that aviation experts, wanted to close National Airport, but the politicians wouldn’t allow it.

 

If I was Trump, I would bring in outside experts from somewhere like Australia, where in my opinion, they do ATC so much better than the Americans.

Rolls-Royce Powers World’s Fastest Offshore Crew Transfer Vessels

The title of this post, is the same as that of this news item from Rolls-Royce.

These three bullet points, act as sub-headings.

  • Sea trials demonstrate maximum speed exceeding 53 knots under operational load.
  • Each of the three ships is powered by four 16-cylinder mtu Series 2000 engines.
  • 35-meter ships are designed as “Surface Effect Ships” (SES)

This is the introductory paragraph.

The Singapore shipbuilder Strategic Marine has commissioned three new offshore supply vessels that, with a maximum speed of over 53 knots, are the fastest of their kind in the world. Each vessel is powered by four 16-cylinder mtu Series 2000M72 engines from Rolls-Royce. The vessels will be used by a national oil company in Africa for passenger transfer to offshore platforms. To enable fast and safe transfer, the 35-meter-long vessels were designed as so-called “Surface Effect Ships”.

This Rolls-Royce image  shows one of the Crew Transfer Vessels at 50 knots.

On a slightly different tack, this Rolls-Royce image  shows The Spirit of Innovation.

Rolls-Royce described it in this press release which is entitled ‘Spirit of Innovation’ Stakes Claim To Be The World’s Fastest All-Electric Vehicle, using these words.

During its record-breaking runs, the aircraft clocked up a maximum speed of 623 km/h (387.4 mph) which we believe makes the ‘Spirit of Innovation’ the world’s fastest all-electric vehicle.

I’ve probably been over 1,300 mph in Concorde.

So are the three offshore supply vessels, the fastest of their kind in the world?

This video shows one of the Crew Transfer Vessels doing, what they are intended to do.

Rolls-Royce seem to be borrowing a philosophy from their past, where they showed in the Schneider Trophy, just what their engines could do.

These two paragraphs describe the design of the Crew Transfer Vessels.

To enable fast and safe passenger transfer to offshore platforms, the 35-meter-long vessels have been designed as so-called “Surface Effect Ships” (SES). SES uses air-cushion technology within a catamaran hull form. This design was used for the first time in the offshore oil and gas industry.

The boats have an optimized power-to-weight ratio and use powerful fans to generate an air cushion between the hulls that minimizes hull drag and resistance. Combined with the mtu propulsion package (each delivering 5,760 kW of power), the vessels can travel at much higher speeds than conventional monohulls and catamarans, with consumption remaining at the same per hour of operations. The high speed of well over 50 knots (more than 90 km/h) ensures shorter transit times, while the low hull resistance saves fuel and reduces emissions.

I believe, that the Rolls-Royce mtu diesel engines used in these vessels can also be fueled by hydrogen, so is that the next development?

Could we be seeing hydrogen-powered fast ferries on short sea routes around the world?
