EMEC And Gravitricity Pick Up Scottish Green Energy Awards
The title of this post, is the same as this article on renews.biz.
These are the first two paragraphs.
The European Marine Energy Centre (EMEC), energy storage innovator Gravitricity and Crown Estate Scotland were among the winners announced last night at the Scottish Green Energy Awards in Edinburgh.
EMEC won the Champion of Renewables award for its ocean energy test facility, while Gravitricity’s energy storage system, which uses excess electricity to winch weights to charge the system and then releases these when energy is required, was announced as the Best Innovation winner.
I am pleased, as I own a small part of Gravitricity, which I contributed through crowdfunding.
Headbolt Lane Station Tipped For Go-Ahead
The title of this post, is the same as that of this article on Place North West.
This is the first paragraph.
Knowsley Council’s December planning committee is expected to approve Network Rail’s plans for a new station in Kirkby.
The article also says that the station could open by Spring 2023.
I wonder, if Liverpudlians will create Headbolt Lane station in record time, as they did a few miles down the line at Maghull North station, which I wrote about in How To Build A Station In Nine Months.
If they do open in early 2023, it is likely to be the first new rail line in the UK, that has been designed to be run by battery-electric trains.
As Liverpudlians like to be first, I would expect that this station will open by Spring 2023. Judging by Network Rail’s performance on bringing the Dartmoor Line to Okehampton station back into service, I don’t suspect it is an impossible dream.
Australian Mining Giant Looks To Canada For Green Hydrogen Projects
The title of this post, is the same as that of this article on the Globe And Mail.
These are the first two paragraphs.
An Australian mining giant has signed agreements with three Canadian Indigenous nations to determine the viability of building green hydrogen projects as the company attempts to reinvent itself as a supplier of clean renewable energy.
Fortescue Future Industries (FFI) sees Canada as potentially one of the largest sources of renewable energy in the world and is hoping to develop multiple large-scale green energy projects here.
The article indicates quite a lot about the future direction of FFI.
I certainly think the company is going the right way.
Thoughts On The Cambo Oil Field
There is an article in The Times today which is entitled Sturgeon Faces Backlash After Shell Pulls Out Of North Sea Oilfield.
I have been following the technology of Carbon Capture and Use and some very good ideas have come forward in the last couple of years.
- Carbon dioxide is becoming increasingly important in the growing of flowers, salad vegetables, soft fruits and tomatoes in greenhouses.
- At COP26, Australian company, Mineral Carbonation International won an award for their process that turns carbon dioxide into building materials like blocks and plasterboard.
- A big investment was also made recently in an Italian company, who are using the properties of liquid and gaseous carbon dioxide to store energy.
- Carbon dioxide has for years made a good fire extinguisher, which can’t be said for some chemicals currently used.
- I suspect that some clever chemists are working on using carbon dioxide to create sustainable aviation fuel.
If the number of ideas for the use of carbon dioxide continues to increase, I can see gas-fired power stations being built, that are also used to produce much-needed high-quality carbon dioxide.
It should also be noted, that many like me, live in houses that are unsuitable for the fitting of heat pumps at an economical cost.
So we must wait for better technology or for hydrogen to be piped into our houses.
In the meantime, we will have to rely on gas. Or freeze!
I don’t know whether Cambo will produce any gas, but if it doesn’t, I can’t see much point in developing it.
Perhaps, Shell would prefer to develop a gas field.
Universal Hydrogen CEO Sees Jetmakers Backing New Fuel
The title of this post is the same as that of this article on Reuters.
It is mainly predictions by Paul Eremenko, who is Chief Executive of Universal Hydrogen, about the future of the single-aisle jet airliner market.
I wrote in detail about their technology in Could Universal Hydrogen’s Concept Create A Hydrogen-Powered Single-Aisle Airliner?.
I firmly believe they have a concept that will work and look forward to flying in a hydrogen-powered aircraft using Universal Hydrogen’s technology before the end of the decade.
Could Universal Hydrogen’s Concept Create A Hydrogen-Powered Single-Aisle Airliner?
Universal Hydrogen are making some of what I would consider the right moves.
Hydrogen Supply
Universal Hydrogen have signed a supply contract with Fortescue Future Industries for the supply of green hydrogen.
The deal is described in this press release on the FFI web site, which is entitled FFI And Universal Hydrogen Join Forces To Decarbonise Aviation.
Collaboration With Airbus
There is an article on BusinessWire, which is entitled Universal Hydrogen Announces New Engineering Development Center Located In Toulouse, France, The Heart of European Aviation.
Toulouse is the home of Airbus.
The Capsule Concept
The capsule concept could be universal.
These are widths of various planes and trains.
- De Havilland Canada Dash 8-400 – 2.52 metres – Internal
- Airbus ATR 72 – 2.57 metres- Internal
- Airbus A320neo – 3.7 metres – Internal
- Boeing 737 – 3.53 metres – Internal
- Class 800 train – 2.7 metres – External
- Class 66 locomotive – 2.65 metres – External
I suspect that if the design is correct, then one size of capsule can be made to fit a variety of applications.
Application To Regional Aviation
I discussed this in Flybe Appears To Be On The Way Back.
I believe that De Havilland Canada Dash 8s and Airbus ATR 72s could be converted to hydrogen.
Road Transport
Surely, the capsules would be too big for road transport in the UK and many other countries.
But they would probably be ideal to deliver hydrogen to bus and truck depots and filling stations for hydrogen vehicles. They would just be plugged in and then could start dispensing the fuel.
Decarbonation Of Diesel Locomotives
Consider.
- The cross-section of a diesel locomotive even in the UK, is larger than that of a regional airliner.
- Most of the space in the body of a diesel locomotive is taken up by a large diesel engine.
- Fuel ells or a small gas turbine could be small compared to the diesel engine.
- Most existing diesel locomotives have electric transmissions.
I believe that many diesel-electric locomotives could be converted to hydrogen power and some could use Universal Hydrogen’s capsules.
Zero-Carbon Backup Generators
Many pieces of important infrastructure, like data centres, hospitals and large railway stations have backup generators.
Universal Hydrogen’s capsules could provide hydrogen for zero-carbon backup generators.
Universal Hydrogen’s Ideas For Single-Aisle Airliners
In the Product page on the Universal Hydrogen web site, there is a section, which is entitled Single Aisle / Narrowbody, where this is the first two sentences.
The majority of aviation emissions are produced by the single aisle (also known as narrowbody) fleet, dominated by the Boeing 737 and Airbus A320 families of aircraft. Both Boeing and Airbus are likely to develop a replacement for these venerable models for entry into service in the mid 2030s.
Alongside the text is this graphic, which compares various airliners.
Universal Hydrogen are proposing that Airbus stretch the A321, so that hydrogen capsules can be fitted in the rear of the fuselage, so that the aircraft has similar proportions to the Boeing 757.
Read the full text on the Product page of the Universal Hydrogen web site.
I can see that if they could prove the concept with the Regional Airliner, they could develop the two concepts shown in the graphic.
Conclusion
This is a simple, but very exciting project.
Flybe Appears To Be On The Way Back
I was alerted to the relaunch of the Flybe airline being a serious proposition by this article on the Birmingham Mail, which is entitled Watch As First Of 32 New Flybe Planes Lands At Birmingham Airport.
These are the first two paragraphs.
The first of Flybe’s more eco-friendly planes has landed in Birmingham ready for the launch of the airline’s new city HQ.
Part of a planned 32-aircraft fleet, the De Havilland Canada Dash 8-400 turboprop touched down on the runway at Birmingham Airport on Friday.
The new Flybe will be based at Birmingham Airport and will have a fleet consisting of thirty-two De Havilland Canada Dash 8-400 aircraft.
The De Havilland Canada Dash 8-400
Note these facts about the aircraft.
- According to Wikipedia, 645 aircraft have been ordered, with 587 having been delivered.
- Different variants can handle between 40 and 80 passengers.
- All aircraft delivered since 1996 are dubbed Q-Series and have active noise and vibration suppression, which is designed to improve the cabin ambience.
- A Dash 8-400 is also called a Q400.
But the most interesting development of the Dash 8 aircraft, is that developments are underway, so that the aircraft will be able to be powered by hydrogen.
Universal Hydrogen And A Hydrogen-Powered Q400
This article on Future Flight is entitled Universal Assembles Hydrogen Aircraft Conversion Team In Washington State.
This is the first two paragraphs.
Universal Hydrogen and its hydrogen fuel cell partner Plug Power are joining forces with electric motor specialists MagniX and AeroTec to set up a Hydrogen Aviation Test and Service Center at Grant County International Airport in Moses Lake, Washington. The partners will use the new facility to convert a Dash 8 regional airliner to hydrogen propulsion in time to start commercial operations in 2025. Flight testing is due to begin in 2022.
The new hydrogen powertrain will consist of an electric propulsion unit (EPU) developed by MagniX and fuel cells provided by Plug Power, which has extensive experience converting trucks to hydrogen. Seattle-based AeroTec will take the lead on converting the Dash 8s to hydrogen propulsion, conducting flight tests, and arranging for certification under FAA supplemental type certificates. The system installation work will be conducted at the Moses Lake facility.
This paragraph gives details of the design.
The hydrogen-powered Dash 8 aircraft, which carry between 41 and 60 passengers, will be able to operate on routes of up to around 625 miles. Universal Hydrogen’s plan calls for the fuel to be delivered directly to aircraft in capsules that are installed in a compartment at the rear of the fuselage.
These are my thoughts on the design.
Power Required
Wikipedia says this about the engines of the Dash 8-400 (Q400).
The Series 400 uses Pratt & Whitney Canada PW150A engines rated at 4,850 shp (3,620 kW).
This means that the aircraft will need fuel cells capable of delivering over 7 MW.
This data sheet on the Plug Power web site, says that the company has fuel cells up to 125 KW, which weigh 350 Kg and need a cooling module, that weighs a further 103 Kg. Scaling up shows the power unit could weigh around 25.4 tonnes.
As the maximum take-off weight of a Q400 is around 30.5 tonnes, this wouldn’t leave much weight for the airframe, the two electric motors and propellers, the hydrogen and the passengers and their luggage.
It would appear that Plug Power must be using some form of lighter-weight fuel cell.
Or could they be using an appropriately-sized gas turbine generator from Pratt & Whitney Canada?
It should be noted that a Pratt & Whitney Canada PW150A engine, weighs under a tonne and generates over 3.5 MW.
Obviously, they wouldn’t be developing the plane, if they hadn’t figured out how to generate enough electricity to get it off the ground.
The Hydrogen Capsules
The Product page on the Universal Hydrogen web site is revealing.
This paragraph from the Product page describes how they would convert Regional Aircraft to Hydrogen.
Our first product is a conversion kit for existing regional aircraft, starting with the ATR72 and the De Havilland Canada Dash-8, to fly on hydrogen. This consists of a fuel cell electric powertrain that replaces the existing turboprop engines. It also accommodates, in the rear of the fuselage, our proprietary, lightweight, modular hydrogen capsules that are transported from green hydrogen production sites to the airport and loaded directly into the aircraft using the existing intermodal freight network and cargo handling equipment. By providing both an aircraft conversion solution for the existing fleet and a fuel services offering directly to regional airlines, we will be in passenger service with zero emissions by 2025 and in cargo service shortly thereafter.
Note.
- The cutaway on the Product page of a De Havilland Canada Dash-8, which has three capsules in the rear fuselage.
- The cutaway shows forty seats in the aircraft.
- If you scroll the pictures, you’ll see the design of the capsule.
- The product can be used to convert two regional airliners both of which are in production.
- Airports will need no new infrastructure to handle the hydrogen.
Universal Hydrogen has also signed a deal with Fortescue Future Industries to supply green hydrogen to fill the capsules.
Are A First Flight In 2022 And An in-Service Date Of 2025 Over Ambitious?
The article in Future Flight says this.
AeroTec will take the lead on converting the Dash 8s to hydrogen propulsion, conducting flight tests, and arranging for certification under FAA supplemental type certificates.
FAA Supplemental Type Certificates are outlined on this page on the FAA web site, where this introductory paragraph is given.
A supplemental type certificate (STC) is a type certificate (TC) issued when an applicant has received FAA approval to modify an aeronautical product from its original design. The STC, which incorporates by reference the related TC, approves not only the modification but also how that modification affects the original design.
They are a much-used and well-proven method to update aircraft for new purposes and new power units.
I suspect that going this route will enable Q400 and ATR 72 aircraft will be flying on hydrogen by 2025.
How Far Will A Range Of 625 Miles Take The Plane From Birmingham?
I have used the Air Miles Calculator to calculate distances in miles from Birmingham.
- Amsterdam Schiphol – 276
- Barcelona – 791
- Belfast City 225
- Berlin Schönefeld – 644
- Biarritz – 621
- Bilbao – 635
- Bordeaux – 529
- Cologne – 397
- Copenhagen – 624
- Cork – 290
- Dublin – 200
- Dusseldorf – 373
- Edinburgh – 251
- Frankfurt – 452
- Geneva – 556
- Glasgow – 260
- Hamburg – 495
- Inverness – 364
- Jersey – 225
- Kirkwall – 474
- Lerwick – 536
- Lyon – 558
- Munich – 660
- Newcastle – 179
- Newquay – 198
- Nice – 735
- Oslo – 726
- Paris-Charles de Gaulle – 303
- Paris-Orly – 315
- Rotterdam – 265
- Strasbourg – 494
Note.
- It might be possible to serve some routes without refuelling at the other end.
- Some routes could be paired for efficiency and still be well below 600 miles.
- The large intercontinental airports of Amsterdam Schiphol, Frankfurt and Paris-Charles de Gaulle should be reached easily.
- Amsterdam Schiphol Airport has a well-connected railway station.
- Paris-Charles de Gaulle Airport has a TGV station.
- Frankfurt Airport has a long distance railway station on the Cologne-Frankfurt high speed line.
- If you’re flying to the South of France or Switzerland, it looks like flying from London City Airport is about a hundred miles shorter.
It would appear that the range of 625 miles could be very useful, especially if you use a long distance train at both ends of the flight.
I can certainly understand why Flybe has chosen Birmingham as its main base.
Will Flybe Convert Their Aircraft To Hydrogen?
This is obviously up to the company, but if they don’t, someone else will and Flybe will lose their regional market in the UK.
Conclusion
I think those behind the new Flybe could be looking to create the UK’s first zero-carbon airline.
Storm Arwen: Image Shows Severe Damage To Train Following Red Weather Warning
The title of this post, is the same as that of this article on the Scotsman.
It shows a dramatic picture of a Class 170 train, that was hit by a tree, that was blown onto the line.
The incident happened on the Borders Railway and luckily no-one was hurt.
Engineers At Network Rail Are Building A Tiny Railway Crossing For Wild Hazel Dormice To Help Protect The Endangered Species From Extinction
The title of this post is the same as that of this article on Railway News.
This is the brief introductory paragraph.
This dormouse bridge will be the first of its kind. It will be built in summer 2022 on the Furness line in Lancashire.
Let’s hope after all this care and work, the dormice like it.
