10GW Green Hydrogen Project Aims To Electrolyze Water Drawn From Desert Air
The title of this post, is the same as that of this article on Hydrogen Fuel News.
This is the first paragraph.
Desert Bloom, an AUD$10.75 billion (USD $7.63 billion) 10GW green hydrogen project will begin construction in Australia’s Northern Territory in 2022.
Desert Bloom is not a small project and uses new technology from Aqua Aerem.
ZeroAvia Raises $35 Million From United And Alaska Air Group to Provide Hydrogen-Electric Engines For Large Aircraft
The title of this post, is the same as that of this article on Aviation Today.
This is the first paragraph.
United Airlines announced an investment this week in ZeroAvia’s hydrogen-electric engines. ZeroAvia has secured $35 million in this latest round of investments from both United and Alaska Air Group. The total amount of investments in ZeroAvia is now $115 million and includes previous investors AP Ventures, Horizons Ventures, Shell Ventures, Breakthrough Energy Ventures, Summa Equity, and Amazon’s Climate Pledge Fund.
ZeroAvia certainly seem to be bringing in the investment.
After, yesterday’s trip in a dual-fuel train, lower- and zero-carbon fuels seem to be on the way.
Hydrogen Freight Locomotive Demonstration Planned
The title of this post, is the same as that, of this article on Railway Gazette.
The first two paragraphs explain the project.
Progress Rail, BNSF and Chevron have signed a memorandum of understanding to develop a fuel cell demonstrator locomotive to assess the viability of using hydrogen as an alternative to diesel for main line freight operations.
Progress Rail plans to design and build a prototype fuel cell locomotive, with Chevron developing the hydrogen fuelling infrastructure. BNSF would then operate the locomotive for a period of time.
It can’t be long before we start to see large-scale hydrogen locomotive projects in the UK and Europe.
Hydrogen Hub Plan Will Cut Transport Sector Emissions In The Highlands
The total of this post, is the same as that of this article on the Ross-Shire Journal.
This is the introduction to the article.
The site of one of the Highland capital’s most distinctive industrial landmarks is set to take on new life and a new role, helping decarbonise transport in the region.
The former SGN gas holder site on Harbour Road, Inverness, has been identified by H2 Green as an ideal location for its new green hydrogen production, storage, and distribution facility.
H2 Green, which is part of the Getech Group, signed a deal with gas network operator SGN for use of the site, which lies between Inverness’s rail depot and industrial area.
This Google Map shows the centre of Inverness.
Note.
- Inverness station in the South West corner of the map.
- Inverness bus station is nearby.
- Harbour Road runs across the top of the map.
It looks to me that the round structure in the North East corner is the former SGN gas holder.
These are my thoughts.
The Size Of The Electrolyser
At eight tonnes of hydrogen per day, the proposed electrolyser would be almost as big as the Herne Bay Electrolyser, which creates ten tonnes of hydrogen per day.
Could The Gas Holder Be Used To Store Hydrogen?
As the gas holder was probably built for town gas, which contains a lot of hydrogen, I suspect it could be refurbished to hold hydrogen.
Oxygen Production
The article also says this about oxygen production.
The hub could also provide zero-carbon heat and medical-grade oxygen for hospitals, aquaculture and water treatment works in the area.
Could it be that oxygen is at a premium in the Highlands, so H2 Green are filling a need?
At the height of the pandemic, when hospitals had an oxygen shortage, I asked ITM Power, if they could produce medical grade oxygen, as a by-product of creating hydrogen. They replied in the affirmative.
Conclusion
It looks to me, that H2 Green have a well-thought out plan for hydrogen in The Highlands.
Opel Begins Production And Deliveries Of Hydrogen Vivaro Van
The title of this post, is the same as that of this article on Green Car Congress.
This is the first paragraph.
Opel has begun production of the hydrogen fuel cell variant of the Vivaro van, and has delivered the first one to the German manufacturer of premium domestic appliances, Miele. The hydrogen fuel cell vehicle will perform daily field service in the Rhine-Main region.
We need more hydrogen filling stations in the UK, so we can use vans like these.
Hydrogen Fuel Cell Locomotive From Canadian Pacific To Roll Out Before 2022
The title of this post, is the same as that of this article on Hydrogen Fuel News.
This is said.
The hydrogen fuel cell locomotive consists of an SD40-2F, which was converted to run on H2 power and is therefore nicknamed the H2 0EL. The company is calling it a “hydrogen zero-emissions locomotive”, and it will be operating under its own power before the end of this month, according to Canadian Pacific CEO Keith Creel.
Note that the SD40 locomotive is a diesel-electric locomotive of which 1286 were built around 1970.
Canadian Pacific have made this video, which was kindly pointed out by Alan.
The video seems to indicate that the converted locomotive will be able to continue to do the same duties as the original diesels, which have a power output of 2,240 kW.
Interestingly, power output seems to be of the same order as that of a Class 66 locomotive, so could a similar conversion by used with these locomotives?
When It Comes To Buses, Will Hydrogen Or Electric Win?
The title of this post, is the same as that of this evcellent article on WIRED.
The WIRED article is a serious comparison between the merits of battery and hydrogen-powered buses.
The writer of the article talked to two people, who should know.
- James Dixon, who is a Research Fellow in the Transport Studies Unit and Environmental Change Institute at Oxford University
- Neil Collins, who is Managing Director of Wrightbus.
I think the philosophy of Wrightbus with four basic zero-carbon buses could be right.
- Streetdeck Hydroliner FCEV – A hydrogen-powered double-deck bus.
- Streetdeck Electroliner BEV – A battery-powered double-deck bus.
- GB Kite Hydroliner FCEV – A hydrogen-powered single-deck bus.
- GB Kite Electroliner BEV – A battery-powered single-deck bus.
This surely is a basis for satisfying customers, who like to buy what they feel is best for their networks and passengers.
This paragraph from the Wired article, illustrates how terrain and climate might favour one bus or the other.
Still, hydrogen may be a better option in a city with lots of hills, like Hong Kong, where it’s also very warm and humid, says Collins. “That’s going to be a problem for electric buses, because the cooling and the hills are just going to drain the batteries,” he says. “But if the city is relatively flat, and the journey times are relatively short, and it’s not either significantly warm or significantly cold, battery electric can do a very good job.”
In addition, you wouldn’t choose hydrogen buses, if supply of hydrogen was difficult.
Could this be why Jo Bamford, who is the owner of Wightbus, has established a company to help bus operators with the transition to hydrogen. I wrote about it in New Company Established To Help Transition Bus Fleets To Hydrogen.
I have also heard stories of garages in city centres, where it is not possible to get enough power to charge a garage full of battery buses. Some of these garages are in residential areas, which perhaps may not welcome tankers of hydrogen going through to supply the buses with hydrogen.
Perhaps, the solution for garages like this is to relocate the garage to a site, which fulfils one of these conditions.
- Good connections to the motorway and trunk road network, so that hydrogen can be brought in by truck.
- A high-capacity electricity supply to either charge battery electric buses or generate hydrogen using an electrolyser.
Buses would operate according to this daily cycle.
- Buses would either be charged or refuelled with hydrogen overnight.
- They would position to a convenient place to start their daily diagrams.
- At the end of the day, they would return to the garage.
Note.
- Battery-electric buses may need to be topped-up during the day.
- Hydrogen buses with their longer range should be able to service routes further away.
- Routes would be arranged, so that hydrogen buses would not need to be topped up.
The big advantage of a remote bus garage is that the city centre site could be redeveloped to pay for the new buses and garage.
Siemens Gamesa Partners On Offshore Wind-to-Hydrogen
The title of this post, is the same as that of this article on renews.biz.
This is the first three paragraphs.
Siemens Gamesa has signed a memorandum of understanding with Strohm to collaborate on the development of offshore wind-to-hydrogen infrastructure.
The partnership will focus on the advancement of hydrogen transfer solutions that will look to improve the decentralized green hydrogen concept, whereby green hydrogen is generated in each turbine generator and transported to shore by a subsea pipe.
In this concept power cables are replaced by a pipe infrastructure used for storing and transferring hydrogen.
Thermoplastic composite pipe (TCP) will be used.
Andrew Forrest, AGL Partner To Explore Hydrogen Option For Hunter Valley Coal Plants
The title of this post, is the same as that of this article on abc.
This is the first paragraph.
Mining billionaire Andrew Forrest said hydrogen would eventually “dwarf” the coal industry as he announced plans to develop a green hydrogen hub in the New South Wales Hunter Valley.
I wish Forrest well with this venture, because if he makes a success of it, it could form a model for lots of other places in the world.
He’s certainly a man on a mission.
Zero-Carbon Emission Flights To Anywhere In The World Possible With Just One Stop
The title of this post, is the same as that of this press release from the Aerospace Technology Institute.
This is the first sentence of the press release.
Passengers could one day fly anywhere in the world with no carbon emissions and just one stop on board a concept aircraft unveiled by the Aerospace Technology Institute (ATI) today.
These three paragraphs describe the concept.
Up to 279 passengers could fly between London and San Francisco, USA direct or Auckland, New Zealand with just one stop with the same speed and comfort as today’s aircraft, revolutionising the future of air travel.
Developed by a team of aerospace and aviation experts from across the UK collaborating on the government backed FlyZero project, the concept demonstrates the huge potential of green liquid hydrogen for air travel not just regionally or in short haul flight but for global connectivity. Liquid hydrogen is a lightweight fuel, which has three times the energy of kerosene and sixty times the energy of batteries per kilogramme and emits no CO2 when burned.
Realising a larger, longer range aircraft also allows the concentration of new infrastructure to fewer international airports accelerating the rollout of a global network of zero-carbon emission flights and tackling emissions from long haul flights.
These are my thoughts.
The Airframe
This picture downloaded from the Aerospace Technology Institute web site is a visualisation of their Fly Anywhere Aircraft.
Some features stand out.
The wings are long, narrow and thin, almost like those of a sailplane. High aspect ratio wings like these offer more lift and stability at high altitude, so will the plane fly higher than the 41,000-43,000 feet of an Airbus A350?
I wouldn’t be surprised if it does, as the higher you go, the thinner the air and the less fuel you will burn to maintain speed and altitude.
The horizontal stabiliser is also small as this will reduce drag and better balance with the wing.
The tailfin also appears small for drag reduction.
The body is bloated compared to say an Airbus A 350 or a Boeing 777. Could this be to provide space for the liquid hydrogen, which can’t be stored in the thin wings?
The fuselage also appears to be a lifting body, with the wings blended into the fat body. I suspect that the hydrogen is carried in this part of the fuselage, which would be about the centre of lift of the aeroplane.
The design of the airframe appears to be all about the following.
- Low drag.
- high lift and stability.
- Large internal capacity to hold the liquid hydrogen.
It may just look fat, but it could be as radical as the first Boeing 747 was in 1969.
The Engines
I suspect the engines will be developments of current engines like the Rolls-Royce Trent XWB, which will be modified to run on hydrogen.
If they are modified Trent engines, it will be astonishing to think, that these engines can be traced in an unbroken line to the RB211, which was first run in 1969.
The Flight Controls
Most airliners these days and certainly all those built by Airbus have sophisticated computer control systems and this plane will take them to another level.
The Flight Profile
If you want to fly any aircraft a long distance, you generally climb to a high level fairly quickly and then fly straight and level, before timing the descent so you land at the destination with as small amount of fuel as is safe, to allow a diversion to another airport.
I once flew from Southend to Naples in a Cessna 340.
- I made sure that the tanks were filled to the brim with fuel.
- I climbed to a high altitude as I left Southend Airport.
- For the journey across France I asked for and was given a transit at Flight Level 195 (19,500 feet), which was all legal in France under visual flight rules.
- When the French handed me over to the Italians, legally I should have descended, but the Italians thought I’d been happy across France at FL195, so they didn’t bother to ask me to descend.
- I flew down the West Coast of Italy at the same height, with an airspeed of 185 knots (213 mph)
- I was then vectored into Naples Airport by radar.
I remember the flight of 981 miles took around six hours. That is an average of 163.5 mph.
I would expect the proposed aircraft would fly a similar profile, but the high level cruise would be somewhere above the 41,000-43,000 feet of an Airbus A 350. We must have a lot of data about flying higher as Concorde flew at 60,000 feet and some military aircraft fly at over 80,000 feet.
The press release talks about London to San Francisco, which is a distance of 5368 miles.
This aircraft wouldn’t sell unless it was able to beat current flight time of eleven hours and five minutes on that route.
Ground Handling
When the Boeing 747 started flying in the 1970s, size was a big problem and this aircraft with its long wing may need modifications to runways, taxiways and terminals.
Passenger Capacity
The press release states that the capacity of the aircraft will be 279 passengers, as against the 315 and 369 passengers of the two versions of the A 350.
So will there be more flights carrying less passengers?
Liquid Hydrogen Refuelling
NASA were doing this successfully in the 1960s for Saturn rockets and the Space Shuttle.
Conclusion
This aircraft is feasible.
