The ZEROe Demonstrator Has Arrived
The title of this post, is the same as that of this press release from Airbus.
This is the introductory paragraph.
2022 marks a new and exciting phase for ZEROe – Airbus’ ambition to develop the world’s first zero-emission commercial aircraft by 2035. The multi-year demonstrator programme has officially been launched with the objective to test a variety of hydrogen technologies both on the ground and in the air.
The ZEROe demonstrator will be the first Airbus A 380 aircraft and it is shown in this Airbus visualisation.
Note.
- The four hydrogen tanks in the fuselage.
- The fifth engine mounted in a pod on the fuselage.
- There’s certainly lots of space inside the fuselage for more hydrogen tanks and test and monitoring equipment.
I have a few thoughts.
This Aircraft Will Be A Superb Demonstrator
The press release says this about the use of an A 380 as a demonstrator.
The A380 is the world’s largest and most spacious passenger jet ever built – a size that makes it ideally suited to the role of test platform.
Today, the A380 MSN1 test aircraft is earmarked for a new role: to take the lead on testing the technologies that will be vital to bringing the world’s first zero-emission aircraft to market by 2035.
“The A380 MSN1 is an excellent flight laboratory platform for new hydrogen technologies,” says Mathias Andriamisaina, Airbus ZEROe Demonstrator Leader. “It’s a safe and reliable platform that is highly versatile to test a wide range of zero-emission technologies. In addition, the platform can comfortably accommodate the large flight test instrumentation that will be needed to analyse the performance of the hydrogen in the hydrogen-propulsion system.”
Initially, I suspect the aircraft will fly as a four-engined turbofan aircraft running on standard or sustainable aviation fuel.
The performance of the hydrogen engine will be tested in all phases of operation and at different altitudes.
What Size Is The Fifth Engine?
This layout is clever.
If Airbus want to test a smaller hydrogen engine for say an Airbus A 320-sized hydrogen aircraft like the ZEROe Turbofan shown in this Airbus visualisation, they fit it to the fifth pylon.
Note.
- The fifth pylon on the ZEROe Demonstrator could be the proposed pylon for the ZEROe Turbofan.
- The ZEROe Demonstrator could probably carry a lot of hydrogen to test out the hydrogen engine over a long duration.
- The hydrogen engine could be tested out over the full flight envelop of an Airbus A 380.
I would suspect that the tests on the hydrogen engine would be some of the most comprehensive ever carried out on a new engine.
If Airbus want to test a larger hydrogen engine for say an Airbus A 350-sized hydrogen aircraft, they would probably replace one of the four main engines with the hydrogen engine.
It looks like Airbus will be able to test hydrogen engines for all sizes of plane in their current range.
What Will Happen To Current A 380s?
Consider.
- The production of the A 380 has been stopped.
- There are 251 aircraft in service.
- They appear to be a reliable and safe aircraft.
- The aircraft can run on sustainable aviation fuel.
- The oldest aircraft are only thirteen years old.
- They are still reasonably modern aircraft, that if they needed to be updated to the latest standards could probably be easily done so.
- The aircraft have a lot of volume, which can hold over 500 passengers in a typical configuration.
- The flying characteristics and structure of the aircraft is well known.
I suspect there are a lot of aircraft leasing companies, who feel these aircraft are too good to scrap, just because they are not zero-carbon.
Could Hydrogen Be Stored In The Wing Of An A 380?
Hydrogen storage will get more capable in the next few years and we will see hydrogen stored in strange places in vehicles and aircraft using the gas as a fuel.
The A 380 may well have an advantage in that its wing is relatively thick compared to that of other airliners.
- The A 380 has a wing aspect ratio of 7.53.
- The Boeing 787 has a wing aspect ratio of 11.
- Gliders have wing aspect ratios as upwards of 30.
High aspect ratios are generally more economical on fuel.
But this relatively thick wing, may make it possible to store hydrogen in the wing of an A 380.
Could There Be A Hydrogen-Powered A 380?
I suspect part of the Airbus ZEROe progam will be to investigate the possibility of converting existing A 380 aircraft into a capable hydrogen-powered aircraft.
In Could An A320 neo Be Rebuilt As A ZEROe Turbofan?, I looked at the possibility of turning an existing Airbus A 320 neo into a ZEROe Turbofan running on hydrogen.
This was my conclusion.
I very much feel that there will be a route to convert some or all of the A 320 neo aircraft to hydrogen power.
So what will a ZEROe A 380 look like if it follows the same design route as an A 320 neo to a ZEROe Turbofan?
- There would be a large hydrogen tank in the rear fuselage.
- As I explained earlier, there may be a possibility for some hydrogen to be stored in the wing.
- Both passenger decks would be shortened and perhaps be able to hold the 350-410 passengers of the Airbus A350-1000.
- The cockpit, front part of the fuselage, wings, tailplane and landing gear would be unchanged.
- The aircraft would fit existing jetways at any airport, that can handle an existing A 380.
I believe that converting an existing Airbus A380 to a hydrogen-powered aircraft is possible and the conversion falls within Barnes Wallis‘s rule of problem solving.
There is no greater thrill in life, that proving something is impossible and then showing how it can be done.
The quote comes from a BBC program, where he was interviewed by Chris Brasher, who was another for whom impossible was just a minor hurdle in the way of meeting objectives.
Could There Be A Hydrogen-Powered A 380 Freighter?
Consider.
- I think it is likely, that companies like Amazon will come under pressure over their carbon footprint, as they transport increasing numbers of packages around the world.
- In DHL Express Shapes Future For Sustainable Aviation With First Order Of All-Electric Cargo Planes From Eviation, I talk about how DHL Express have ordered twelve Eviation Alice aircraft to create a zero-carbon service. DHL must feel this would be good for their image. So would they like an intercontinental zero-carbon freighter?
- Some people worry about the air-miles on their food!
There could be a worthwhile niche market for a high capacity intercontinental zero-carbon freighter.
Because it has such a large internal volume, an Airbus A 380 might make an ideal aircraft to convert.
Conclusion
Airbus will learn a lot from the ZEROe Demonstrator.
They may even learn how to develop, a long-range hydrogen-powered zero-carbon A 380 variant that could carry four hundred passengers between Europe and Australia.
Hydrogen Fuel Cell Trucks And H2 Infrastructure Could Benefit From New Legislation
The title of this post, is the same as that of this article on Hydrogen Fuel News.
Politicians from both main parties in the United States are promoting a Hydrogen for Trucks Act, to support the conversion of domestic trucking from diesel to hydrogen.
These are the three main parts of the Act
- Provide incentives for adopting hydrogen fuel cell trucks by covering the difference in cost between them and conventional diesel-powered vehicles.
- Encourage tandem fueling station and vehicle deployment, to ensure that one doesn’t need to exist before the other is in place, solidifying the overall fueling infrastructure.
- Collect data and establish benchmarks for various forms of fleet operation, helping to accelerate deployment by incentivizing private investment.
We could do with an Act like this in the UK.
But whereas the United States would start with hydrogen for trucks, we would probably start with hydrogen for buses.
Shell And ScottishPower Win Bids To Develop 5 GW Of Floating Wind Power In The UK
The title of this post, is the same as that of this press release from Shell.
This is three paragraphs from the press release.
Shell and ScottishPower have secured joint offers for seabed rights to develop large-scale floating wind farms as part of Crown Estate Scotland’s ScotWind leasing. The partners have won two sites representing a total of 5 gigawatts (GW) off the east and north-east coast of Scotland.
The new wind farms will be delivered through two joint ventures called MarramWind and CampionWind. They bring together ScottishPower’s and Shell’s decades of experience working offshore and significant presence in Scotland, as well as their strong innovation capabilities for delivering world-class offshore energy projects.
The development, construction and operation of ScotWind projects is set to bring new skilled jobs and manufacturing opportunities and boost local supply chains.
ScottishPower are actually involved in three large ScotWind projects; one by themselves and two in partnership with Shell.
MacHairWind
MachairWind is a project that Scottish Power is developing alone.
- It has its own page on the ScottishPower Renewables web site.
- It will be a 2 GW wind farm to the North-West of Islay.
- The turbines will be on fixed foundations.
I wrote about this project in MacHairWind Wind Farm.
MarramWind And CampionWind
These two wind farms are being developed in partnership with Shell.
They both have their own web sites.
MarramWind’s web site has this introduction.
ScottishPower and Shell have joined forces to develop the MarramWind offshore windfarm following success in the recent ScotWind auction process by Crown Estate Scotland.
Located 75 kilometres off the North East coast of Scotland in water depths averaging 100 metres, the proposed MarramWind floating offshore windfarm could deliver up to 3 gigawatts (GW) of cleaner renewable energy.
This map clipped from the MarramWind web site, shows the location of the wind farm.
CampionWind’s web site has this introduction.
ScottishPower and Shell have joined forces to develop the CampionWind offshore windfarm following success in the recent ScotWind auction process by Crown Estate Scotland.
Located 100 kilometres from the east coast of Scotland, in water depths averaging 77 metres, the proposed CampionWind floating offshore windfarm could deliver up to 2 gigawatts (GW) of cleaner renewable energy.
This map clipped from the CampionWind web site, shows the location of the wind farm.
Note.
- The two wind farms will be within a few miles of each other.
- Both wind farms will use floating wind turbines.
- The water is a bit deeper at MarramWind, but this surely doesn’t bother a floating turbine.
- MarramWind and CampionWind will have a total capacity of 5 GW.
- Hywind Scotland is the world’s first commercial wind farm using floating wind turbines, situated 29 kilometres off Peterhead. This wind farm is only 30 MW, but in its first years of operation has achieved a capacity factor of over 50 %.
- The proposed turbines at Northern Horizons‘ 10 GW wind farm, which is 130 kilometres to the North-East of Shetland will be 20 MW giants and nearly as tall as The Shard in London.
So will Scottish Power and Shell design and build a combined field, similar in concept to Northern Horizons’ wind farm, using an armada of 250 floating wind turbines?
- The wind turbines might be moored around a fixed or floating mother platform or structure, that will collect the electricity and deliver it to the shore.
- Turbines could be serviced in situ or moved into port, as needed.
- Extending the wind farm could just be a matter of mooring the extra turbines in position and then connecting them to the mother platform.
- Is there a convenient disused oil or gas platform, that could be repurposed as the mother platform?
It certainly would appear to be a way of building large offshore fields in deep waters.
Where Would The Combined MarramWind And CampionWind Rank In Terms of UK Wind Farms?
Consider.
- MarramWind and CampionWind will have a total capacity of 5 GW.
- Phase one of the Hornsea Wind Farm is the largest offshore wind farm in the world, with a capacity of just over 1.2 GW and when complete it will have a capacity of 6 GW.
- Northern Horizons is planned to be 10 GW.
- The East Anglian Array could be as large as 7.2 GW.
- The Dogger Bank Wind Farm is planned to be as large as 4.8 MW.
- Norfolk Vanguard and Norfolk Boreas are a pair of 1.8 GW wind farms.
- MacHairWind will be a 2 GW wind farm.
Note.
- This is not a complete list of large wind farms in the development pipeline.
- BP have obtained leases, but have not published their plans.
- Most farms under development are at least one GW.
- These farms are a total of 38.6 GW.
The Combined MarramWind and CampionWind would be one of several large wind farms around 5 GW.
There Is A Desperate Need For Energy Storage
If we are generating upwards of 40 GW of wind and solar energy in the UK, there will be a desperate need for energy storage to cover for the times, when the wind doesn’t blow and the sun doesn’t shine.
Scotland should be OK, as there are various energy storage projects in development.
- The 1.5 GW/ 30 GWh Coire Glas project is according to SSE shovel-ready and has planning permission.
- The 450 MW/2.8 GWh Red John project is being constructed.
- Drax, ILI Group and SSE have several other projects under development.
So what would happen in the South?
The government appears to be on the case as I wrote in Ministerial Roundtable Seeks To Unlock Investment In UK Energy Storage.
But there is also the possibility of using hydrogen.
- Hydrogen could be created by a series of giant electrolysers.
- It could be blended with natural gas to eke out our natural gas and save carbon. According to HyDeploy, it appears that up to 20 % can be added, without needing to change boilers and appliances.
- It can be stored in depleted offshore gas fields.
- It can be used to power heavy transport like buses, trucks, trains and ships.
- It can be burned in gas-fired power stations to generate electricity.
Hydrogen can also be used as a feedstock or green energy source for the making of chemicals, concrete and steel.
Conclusion
We are approaching the end of the first phase of the development of renewable energy in the UK.
Massive floating wind farms using armadas of floating wind farms, a large expansion of pumped storage hydro and a huge expansion of the use of hydrogen will see us through to a carbon-free future.
TransPennine Express Explores Further Fleet And Capacity Expansion Options
The title of this post, is the same as that of this article on Railway Gazette.
This is the first paragraph.
First TransPennine Express is hopeful that it will be able to issue a call for expressions of interest in the provision of additional bi-mode trains before the end of March. This follows ‘a healthy level of interest’ in its existing call for expressions of interest in the supply of bi-mode locomotives to replace the Class 68s which work with its MkVa coaches.
I wrote about the expressions of interest to replace the Class 68 locomotives with new bi-mode locomotives in Suppliers Sought For New Bi-Mode Locomotives For TransPennine Express And Great Western Railway.
This was my conclusion in the related post.
When I saw First Group’s proposals, I thought that they were over ambitious.
But after doing a few simple calculations, I think they can decarbonise some, but not all of the TransPennine Express services and the Night Riviera.
So do First Group want to complete the decarbonisation of TransPennine Express services?
These are my thoughts.
The Train Fleet Specification
The Railway Gazette article makes these points about the new bi-mode trains.
- The trains could be existing or new bi-modes.
- It would be desirable for the trains to have a long-term electric-only option.
- Options for this would include removing the diesel engines or converting the trains to battery-electric operation.
- Hydrogen is not mentioned.
- A fleet size of twenty-five trains is mentioned.
- The possibility of electric-only trains in the future is mentioned..
- Five-cars, with the ability to lengthen to six- or seven-cars.
- 200 km/h operation.
There is nothing unusual in the specification.
Will They Be Existing Or New Trains?
I doubt that there are any existing 200 km/h bi-modes in the UK, that are not wanted by their current operators.
I am very certain they will be new trains.
Could The Trains Be Hitachi Class 802 Trains?
The trains sound very much like Hitachi Class 802 trains, that are in service with TransPennine Express, Great Western Railway and Hull Trains, all of whom are First Group companies.
- Long-term, the diesel engines can be removed or replaced with batteries.
- The battery option is under development and should be on test this year.
- The trains can be lengthened to as long as twelve cars, so six- and seven-car trains would be possible.
Hitachi will obviously show interest in this possible order.
Will These Trains Replace the Class 185 Trains?
Consider.
- TransPennine Express have 51 three-car Class 185 trains.
- This is a total of 153 cars.
- On some routes they work singly and on others they work in pairs.
- A three-car Class 185 train has 167 Standard Class and 15 First Class seats or 60.7 seats per car.
- A pair of Class 185 trains have 334 Standard Class and 30 First Class seats.
- A five-car TransPennine Express Class 802 train has 318 Standard Class and 24 First Class seats or 68.4 seats per car.
- It would appear that a Class 802 train is not that far short of the capacity of a pair of Class 185 trains.
- Some of the TransPennine services are very crowded.
I suspect that twenty-five five-car trains be able to handle the the workload of the Class 185 trains.
If a small amount of extra capacity were needed, some of the new trains could be six-cars.
In this section, I have assumed the new trains will be Class 802 trains, but any train manufacturer pitching for this order would adjust the capacity to the needs of TransPennine Express.
The Railway Gazette article says this.
TPE continues to explore opportunities for new services in the north of England, and the move could also feed into government plans for the removal of older and more costly to operate diesel trains elsewhere on the network, should any rolling stock become surplus to requirements at TPE.
So where could the Class 185 trains be used in the future?
Recently, MTU Hybrid PowerPacks have replaced the transmission on a Class 168 train, which reduces carbon emissions and fuel consumption and makes the train quieter and more passenger-friendly, as it doesn’t use diesel in stations.
The Class 185 trains are only fifteen years old and I suspect that MTU have designed the Hybrid PowerPack, so that it can replace the Cummins engine in trains like these.
The conversion could be done as a rolling program, so that any future operator would start with diesel and go hybrid a train at a time.
There has been speculation, that the trains may end up on the East West Railway and I wrote about this in East West Railway Company To Start Second Phase Of Rolling Stock Procurement.
But the East West Railway may prefer to use zero-carbon trains on a route, where there is electrification in places on the route.
Alternatively, South Western Railway run 10 two-car Class 158 trains and 30 three-car Class 159 trains between London Waterloo and Exeter.
- South Western Railway is another First Group company.
- The Class 185 trains could provide a capacity increase.
- The Class 185 trains are 100 mph trains, whereas the Class 158/159 trains are only capable of 90 mph.
The London Waterloo and Exeter Route could be electrified in the future and I am pretty sure, that the Class 185 trains with a hybrid transmission could be a good stand-in until this happens.
Other Train Manufacturers
I believe that Hitachi are in pole position for this order, just because they are an established supplier to both TransPennine Express and First Group.
But twenty-five five-car trains would be a very worthwhile order, so I suspect that companies like Alstom, CAF, Siemens, Stadler and Talgo will also express interest.
Conclusion
Buying extra bi-mode trains will take TransPennine Express further along the route to full decarbonisation.
My First Encounter With A Robot
Whilst in Bletchley, I saw this robot going about their business.
Note.
- The robot was from robotdelivery.co.uk.
- It was fascinating to see it cross the roads on the zebra crossings.
This idea might take off, as it is surely more environmentally friendly than a guy speeding up and down on a scooter.
Highland Council Forges Green Hydrogen Pact
The title of this post, is the same as that of this article on renews.biz.
These are the first two paragraphs.
Getech subsidiary H2 Green has signed a memorandum of understanding (MoU) with the Highland Council in Scotland aimed at creating a regional network of green hydrogen hubs across the Scottish Highlands.
Under the terms of the MoU, H2 Green and the Highland Council will produce a regional plan to develop a network of green hydrogen hubs at optimal locations across the region.
The first hub appears to be in Inverness, as I wrote in Hydrogen Hub Plan Will Cut Transport Sector Emissions In The Highlands.
But that is only the start.
- Green hydrogen will be used in transport in the Highlands.
- By-products like oxygen and heat will be distributed.
- Delivery of Highland decarbonisation will be planned.
- SGN Commercial Services will service large-volume customers.
- Agreements are in place for Eversholt Rail to deploy their hydrogen-powered trains on the Far North and West Highland Lines of Scotland.
This statement from Jonathan Copus of Getech, sums up the objectives of the hydrogen project.
These activities combined with the Highland Council initiative are set to establish the Highlands as the leading UK-centre for decarbonisation and innovation; they will also support job creation, deliver energy security and provide a sustainable path for the region’s net zero transition.
I believe that a similar approach could be taken in other parts of the UK. Cornwall, East Anglia, Lincolnshire, much of Wales and the Borderlands between England and Scotland come to mind.
Each region will probably, decarbonise slightly differently and each will develop more and more innovative ways to use the hydrogen.
Conclusion
Hydrogen will play a large part in the decarbonisation of the UK.
Earth Friendly Concrete
I was alerted to this product by this article on New Civil Engineer, which is entitled Keltbray Saves Carbon And Money With Earth Friendly Concrete On East London Job.
The article gave enough clues to find the Earth Friendly Concrete home page.
This is the introduction on the page.
We want to have a positive impact on the environment and supply our customers with an excellent product, that is why we created Earth Friendly Concrete ® by Wagners. It is a concrete that uses no ordinary Portland cement, instead using a geopolymer binder system made from the chemical activation of two industrial waste by-products – blast furnace slag (waste from iron production) and fly ash (waste from coal fired power generation). Our product has ZERO Portland cement and it has a much lower embodied energy compared to ordinary concrete, saving 250kg of CO2 for every cubic metre poured. Importantly, the engineering and construction properties of this environmentally friendly concrete is, in some areas, better than normal concrete. EFC has some significant performance advantages over normal Portland cement concrete, including improved durability, lower shrinkage, earlier strength gain, higher flexural tensile strength and increased fire resistance.
On this page, which is entitled About EFC, this said about the products Environmental Excellence.
EFC is a new class of concrete that contains NO ordinary Cement. Globally, the production of 1 tonne of Portland Cement produces 1 tonne of CO₂ emissions and is responsible for 5 to 8% of manmade greenhouse gas emissions. Instead of cement, EFC has a geopolymer binder that is made from the chemical activation of two recycled industrial wastes, flyash and slag. This recycled binder reduces the CO₂ emissions associated with Portland cement by 80 to 90%.
Every m3 of 40 MPa EFC saves 220kg CO₂ emissions.
Wagners, the company behind the development, are based in Queensland. Australia.
So it’s a case of Well Done The Aussies!
They have appointed Capital Concrete, to deliver Earth Friendly Concrete in the London area.
Conclusion
Does High Speed Two and other large projects that will need large amounts of concrete, know about this development?
Aberdeen Unveils UK’s First Green Hydrogen Waste Truck
The title of this post, is the same as that of this article on renews.biz.
These are the first three paragraphs.
The UK’s first green hydrogen-fuelled waste collection vehicle has been unveiled in Aberdeen.
While typical waste trucks are powered by diesel and petrol, the new vehicle will use green hydrogen from existing refuelling infrastructure in Aberdeen.
The truck will start collecting waste and recycling around the city from early March and will be the first hydrogen-powered waste truck to become operational in the UK.
I feel, that this is one of the obvious applications for hydrogen trucks.
- They return to the same depot at the end of the day and if the hydrogen refuelling station is nearby or at the depot, refuelling would be no more hassle than with diesel.
- The trucks are probably too large for battery power.
- They tend to work a lot in areas, where there are a lot of people about, like residential streets and shopping centres.
- Workers will be exposed to less pollution, as they bring bins to the trucks.
Aberdeen Council have provided this video.
I can see lots of Councils at least thinking of following Aberdeen’s example, when they renew their refuse trucks.
Incidentally, I may be only 74, but I can still remember the horse-drawn waste carts that Wood Green Council used to use in the 1950s. They were used around Wood Green town centre, where trailers were parked to receive rubbish from shops and businesses. Horses were used to move them about and to the depot. In the end they horses were replaced by Scammel Mechanical Horses.
Norfolk Wind Farms Offer ‘Significant Benefit’ For Local Economy
The title of this post, is the same as that of this article on the BBC.
This is a comprehensive article, which looks at the benefits of the huge Norfolk Boreas and Norfolk Vanguard wind farms will have to the economy of Norfolk.
The last section is devoted to Norfolk Nimby; Raymond Pearce.
This is the section.
Following the re-approval of the decision by the government, Mr Pearce says he is considering a new appeal over what he calls “a very poor decision”.
He is also sceptical of claims the two new wind farms will bring the economic gains promised by Vattenfall.
“It’s renewable energy at any cost and the cost here is to the environment in Norfolk,” he says.
“I don’t blame them for being positive about it, it’s their industry but they’re not looking at it holistically.”
He says he is not against renewable energy but thinks a better plan is needed to connect the offshore windfarms and minimise the number of cables and substations onshore.
It’s his money if he appeals, but we do need more wind, solar and other zero-carbon energy to combat global warming and its effects like the encroachment of the sea around Norfolk.
I believe, that building wind farms off the coast of Essex, Suffolk and Norfolk is a good move, as in the future, if we have spare electricity, it will be easy to export energy to Europe, through existing interconnectors.
But I do agree with him, that a better plan is needed to connect the offshore windfarms and minimise the number of cables and substations onshore.
A Norfolk Powerhouse
This map from Vattenfall, the developer of the two wind farms, shows the position of the farms and the route of the cable to the shore.
Note.
- The purple line appears to be the UK’s ten mile limit.
- Norfolk Boreas is outlined in blue.
- Norfolk Vanguard is outlined in orange.
- Cables will be run in the grey areas.
- Both wind farms are planned to have a capacity of 1.8 GW
Landfall will be just a few miles to the South of the Bacton gas terminal.
Bacton Gas Terminal
Bacton gas terminal is much more than a simple gas terminal.
- It is a complex of six gas terminals on four sites.
- There is a National Grid terminal, that odourises and blends the gas before distributing it into the National Transmission System via five outgoing 36-inch feeders to much of Southern England.
- There is a gas interconnector to Belgium.
- There is a gas interconnector to The Netherlands.
- There is coastal erosion in the area.
With the need to decarbonise, I can’t help feeling that the Bacton gas terminal is very much on the decline and the site will need to be repurposed in the next few years.
Blending Hydrogen With Natural Gas
If you blend a proportion of hydrogen into natural gas, this has two beneficial effects.
- Gas used in domestic and industrial situations will emit less carbon dioxide.
- In the near future we will be replacing imported natural gas with hydrogen.
The hydrogen could be produced by a giant electrolyser at Bacton powered by the electricity from the two Norfolk wind farms.
At the present time, a research project call HyDeploy is underway, which is investigating the blending of hydrogen into the natural gas supply.
- Partners include Cadent, Northern Gas Networks, the Health and Safety Executive, Keele University and ITM Power and Progessive Energy.
- A first trial at Keele University has been hailed as a success.
- It showed up to twenty percent of hydrogen by volume can be added to the gas network without the need to change any appliances or boilers.
Larger trials are now underway.
A Giant Electrolyser At Bacton
If hydrogen were to be produced at Bacton by a giant electrolyser, it could be used or distributed in one of the following ways.
- Blended with natural gas for gas customers in Southern England.
- Stored in a depleted gas field off the coast at Bacton. Both Baird and Deborah gas fields have been or are being converted to gas storage facilities, connected to Bacton.
- Distributed by truck to hydrogen filling stations and bus and truck garages.
- Greater Anglia might like a hydrogen feed to convert their Class 755 trains to hydrogen power.
- Sent by a short pipeline to the Port of Great Yarmouth and possibly the Port of Lowestoft.
- Exported to Europe, through one of the interconnectors.
Note.
- If the electrolyser were to be able to handle the 3.6 GW of the two wind farms, it would be the largest in the world.
- The size of the electrolyser could be increased over a few years to match the output of the wind farms as more turbines are installed offshore.
- There is no reason, why the electrical connection between Bacton and the landfall of the wind farm cable couldn’t be offshore.
If ITM Power were to supply the electrolyser, it would be built in the largest electrolyser factory in the World, which is in Sheffield in Yorkshire.
A Rail Connection To The Bacton Gas Terminal
This Google Map shows the area between North Walsham and the coast.
Note.
- North Walsham is in the South-Western corner of the map.
- North Walsham station on the Bittern Line is indicated by the red icon.
- The Bacton gas terminal is the trapezoidal-shaped area on the coast, at the top of the map.
I believe it would be possible to build a small rail terminal in the area with a short pipeline connection to Bacton, so that hydrogen could be distributed by train.
How Much Hydrogen Could Be Created By The Norfolk Wind Farms?
In The Mathematics Of Blending Twenty Percent Of Hydrogen Into The UK Gas Grid, I said the following.
Ryze Hydrogen are building the Herne Bay electrolyser.
- It will consume 23 MW of solar and wind power.
- It will produce ten tonnes of hydrogen per day.
The electrolyser will consume 552 MWh to produce ten tonnes of hydrogen, so creating one tonne of hydrogen needs 55.2 MWh of electricity.
Each of the Norfolk wind farms, if they were working flat out would produce 43.2 GWh of electricity in a day.
Dividing the two figures gives a daily production rate of 782.6 tonnes of hydrogen per day.
But what happens if the wind doesn’t blow?
This is where the gas storage in the Baird, Deborah and other depleted gas fields comes in.In times of maximum wind, hydrogen is stored for use when the wind doesn’t blow.
Conclusion
I believe a plan like this, would be much better for Norfolk, the UK and the whole planet.
Using the existing gas network to carry the energy away from Norfolk, could mean that the electricity connection across Norfolk could be scaled back.
Does London Need High Capacity Bus Routes To Extend Crossrail?
If Crossrail has a major problem, it is that some areas of the capital will find it difficult to access the new line.
Up to the age of sixteen, I used to live half-way between Oakwood and Cockfosters stations on the Piccadilly Line.
There are a large number of people who live along the Northern reaches of the Piccadilly Line, who might want to use Crossrail to perhaps go to Heathrow or places in East London.
But the journey will need a double change as there is no interchange between the Piccadilly Line and Crossrail.
I suspect that many will link to Crossrail by taking the Piccadilly Line to Wood Green, Turnpike Lane or Manor House and then get a 141 bus to Moorgate. It is a route, I use if I want to go to Southgate or Cockfosters from my house, which has a 141 stop opposite.
But then as a child to go to Harringay, where my father had an uncle, my mother would use a 641 trolley bus from Wood Green or Turnpike Lane.
Do people follow the public transport habits of their parents?
I know I do!
My father never went on a deep tube. As he several times mentioned the terrible Bank station bombing in the Blitz, which killed 56 people, I always thought that was his problem. But now living as I do along the Northern and Northern City Lines, I suspect it was more to do with air quality, as we were or are both bad breathers.
I suspect that when Crossrail opens, the 141 bus will be heavily used by travellers going between the Northern reaches of the Piccadilly Line and Crossrail at Moorgate.
The 141 bus goes between London Bridge station and Palmers Green and it has a route length of about nine miles.
Currently, buses run every fifteen minutes or so, but I doubt it will be enough in future as Transport for London are rerouting the closely-related 21 bus.
I suspect any route seen as an extension of Crossrail needs to have the following characteristics.
- High frequency of perhaps a bus every ten minutes.
- Interior finish on a par with the Class 345 trains.
- Wi-fi and phone charging.
I would also hope the buses were carbon-free. Given that some of these routes could be quite long, I would suspect hydrogen with its longer range could be better.
Other Routes
According to me, the 141 bus route needs improvement!
But how many other routes could need similar improvement?
