The Anonymous Widower

New Mobile Hydrogen Unit Unveiled By Logan Energy In Bid To Accelerate Greener Transport

The title of this post, is the same as that of this article on Fuel Cell Works.

This sums up the development, that has been unveiled by Logan Energy.

It is a compression trailer, that looks like it could be towed by any vehicle capable of towing a horse box.

  • The compressor can transfer hydrogen between any two cylinders at all the usual pressures.
  • It is aimed at both the bus and heavy goods vehicle market.
  • The hydrogen capacity of the trailer is not stated.

I feel that this sort of development will help operators embrace hydrogen.

A bus company for instance could have an appropriate number of trailers, for their fleet of hydrogen buses.

  • The bus company would need a suitable towing vehicle, like a light truck.
  • Trailers would be filled at an electrolyser outside of the city.
  • Each bus depot could have a space, where a trailer could be parked to fill the buses.
  • A schedule would probably need to be developed for filling the trailers.

We will see more developments like this.

But they will have to compete with companies like ITM Power, who can supply on-site electrolysers.

West Midlands To Run ‘Largest Hydrogen Bus Fleet’ Due To New Funding

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

These are a few points from the article.

  • The region is set to get 124 new hydrogen vehicles.
  • The West Midlands is set to run the UK’s largest hydrogen bus fleet after securing new funding.
  • The region will get 124 new buses after it won £30m from the Department for Transport to fund a switchover.
  • Twenty four of the new vehicles will be articulated tram-style buses set to run on a new bus priority route between Walsall, Birmingham and Solihull.

Does the last statement mean, that they will buying a hundred double-decker hydrogen buses?

A few thoughts.

Riding Birmingham’s New Hydrogen-Powered Buses

These are a few pictures from Riding Birmingham’s New Hydrogen-Powered Buses.

They were excellent buses from Wrightbus.

The Tram Style Buses

The Belgian firm; Van Hool have a product called Exquicity. This video shows them working in Pau in France.

These tram buses run on rubber types and are powered by hydrogen.

Similar buses running in Belfast are diesel-electric.

Could these be what the article refers to as tram-style buses?

It should be noted, that the West Midlands and Pau have bought their hydrogen filling stations from ITM Power in Sheffield.

So has there has been a spot of the Entente Cordiale between Pau and the West Midlands?

Will The West Midlands Buy The Other Hundred Buses From Wrightbus?

There doesn’t seem to be any problems on the web about the initial fleet, so I suspect they will.

It should also be noted that Wrightbus make the following types of zero-emission buses.

These would surely enable the West Midlands to mic-and-match according to their needs.

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.

  1. The purple line appears to be the UK’s ten mile limit.
  2. Norfolk Boreas is outlined in blue.
  3. Norfolk Vanguard is outlined in orange.
  4. Cables will be run in the grey areas.
  5. 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.

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.

  1. 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.
  2. 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.
  3. 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.

  1. North Walsham is in the South-Western corner of the map.
  2. North Walsham station on the Bittern Line is indicated by the red icon.
  3. 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.

The Mathematics Of Blending Twenty Percent Of Hydrogen Into The UK Gas Grid

HyDeploy is a project, that is investigating blending hydrogen into the UK’s natural gas supply to reduce the amount of carbon dioxide produced by the burning of natural gas in power stations, industrial processes and in our homes and other buildings.

To find out more about the project, visit the HyDeploy web site.

This is a paragraph from this page on the HyDeploy web site, which describes the current progress of the project.

HyDeploy is progressing well. The HSE gave the go ahead for a live demonstration, at Keele University, of blended hydrogen and natural gas which began in Autumn 2019 and completed in Spring 2021. The HSE are satisfied that the blend of gas will be as safe as the gas we all currently use. The hydrogen content will be up to 20% and has so far reached 15%.

Note that HSE is the Health and Safety Executive, who are closely involved.

HyDeploy has now moved on to Phase 2 in the North East.

For our North East demonstration, we have contacted everyone who will be involved in that demonstration – more than 650 homes – and arranged for our engineers to carry out Gas Safe checks on their gas appliances and gather information on the range of appliances in the demonstration area. The Gas Safe checks were free of charge. Almost 90% of those homes have engaged with us.

What would be the effects of 20 % of hydrogen blended into natural gas?

Will current boilers, cookers and other gas-powered devices work on a blend of hydrogen and natural gas?

This is one for the scientists and it is one of the objectives of the HyDeploy trial to understand how every use of gas performs if instead of natural gas, the fuel is a mixture of eighty percent natural gas and twenty percent hydrogen.

I will assume that these problems are solvable.

I am not just hoping, but I can remember in the early 1970s, when our elderly gas cooker was successfully converted from town gas, which was typically a mixture of hydrogen (50%), methane (35%),carbon monoxide (10 %) and ethylene (5%), to natural gas, as North Sea gas started to flow.

This document from the UK government is entitled Fuels: Natural Gas, which contains a section entitled Material Properties Relevant To Use, where this is said.

Natural gas is a combustible gas that is a mixture of simple hydrocarbon compounds. It contains primarily methane, along with small amounts of ethane, butane, pentane, and propane. Natural gas does not contain carbon monoxide. The by-products of burning natural gas are primarily carbon dioxide and water vapour. Natural gas is colourless, tasteless and odourless. Because it is odourless, an odorant (80% tertiarybutyl mercaptan, 20% dimethyl sulphide) is added to the gas, to give the gas a distinctive smell. Other beneficial properties of natural gas are a high ignition temperature and a
narrow flammability range, meaning natural gas will ignite at temperatures above 593°degrees and burn at a mix of 4 – 15% volume in air (St. Lawrence Gas, 2015)

As ethane (C2H6), butane (C4H10), pentane (C5H12) and propane (C3H8) are all similar simple hydrocarbons to methane, which burn to produce carbon dioxide and water, I will assume in this analysis, that natural gas is all methane (CH4).

It is reasonable to assume, that currently we use a fuel which is equivalent to 100 % methane and that in the future we could use 80 % methane and 20 % hydrogen. Also in the past, we used to use a fuel, that was 50 % hydrogen and 35 % methane. The carbon monoxide is a poison, so I’ll ignore it, but ethylene (C2H4) is another of those simple hydrocarbons, which burn to release just carbon dioxide and water.

So if we were able to go from town to natural gas fifty years ago, by just adjusting gas equipment, surely we can go partly the other way in the Twenty-First Century.

I can certainly see the UK gas supply containing twenty percent hydrogen, but wouldn’t be surprised to see a higher level of hydrogen in the future.

How Much Hydrogen Needs To Be Added?

This page on worldodometer says this about UK gas consumption.

The United Kingdom consumes 2,795,569 million cubic feet (MMcf) of natural gas per year as of the year 2017.

I will now calculate the weight of hydrogen needed to be added.

  • 2,795,569 million cubic feet converts to 79161.69851 million cubic metres.
  • I will round that to 79161.7 million cubic metres.
  • Twenty percent is 15832.34 million cubic metres.
  • A cubic metre of hydrogen weighs 0.082 Kg, which gives that in a year 1,298.25188 million kilograms will need to be added to the UK gas supply.

This is 1,298,251.88 tonnes per year, 3,556.85 tonnes per day or 148.2 tonnes per hour.

How Much Electricity Is Needed To Create This Amount Of Hydrogen?

In Can The UK Have A Capacity To Create Five GW Of Green Hydrogen?, 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.

To create 148.2 tonnes per hour of hydrogen would need 8,180.64 MW of electricity or just under 8.2 GW.

How Much Carbon Dioxide Would Be Saved?

This page on the Engineering Toolbox is entitled Combustion Of Fuels – Carbon Dioxide Emission and it gives a list of how much carbon dioxide is emitted, when a fuel is burned.

For each Kg of these fuels, the following Kg of carbon dioxide will be released on combustion.

  • Methane – 2.75
  • Gasoline – 3.30
  • Kerosene – 3.00
  • Diesel – 3.15
  • Bituminous coal – 2.38
  • Lignite 1.10
  • Wood – 1.83

Engineering Toolbox seems a very useful web site.

I will now calculate how much carbon dioxide would be saved.

  • In 2017, UK methane consumption was 79161.7 million cubic metres.
  • One cubic metre of methane weighs 0.554 Kg.
  • The total weight of methane used is 43,855,581.8 tonnes.
  • Multiplying by 2.75 shows that 120,602,849.95 tonnes of carbon dioxide will be produced.

As twenty percent will be replaced by hydrogen, carbon dioxide emission savings will be 24,120,569.99 tonnes.

That seems a good saving, from a small country like the UK.

The UK would also reduce natural gas consumption by twenty percent or 15832.34 million cubic metres per year.

How many other countries with good renewable and zero-carbon electricity resources like Australia, Chile, Denmark, France, Iceland, Ireland, Jordan, Morocco, Norway, Sweden and the United States will take this route, as it seems a good way to save large amounts of carbon?

There is also the collateral benefit, that countries with a good supply of hydrogen can use hydrogen to decarbonise the heavy transport sectors of rail, road and sea freight transport.

The big winners would appear to be those companies like ITM Power, who manufacture electrolysers and those companies like Fortescue Future Industries, who are prospecting, developing and promoting the hydrogen resources of the planet.

The losers will be countries, who are reliant on importing large amounts of gas and other fossil fuels, who don’t have access to large amounts of renewable energy like geothermal, hydro, nuclear, solar and wind.

Germany’s energy policy of no nuclear, more coal and Russian gas seems to have been a mistake.

But I’m sure, if Olaf Sholz talked nicely to Boris, there is a deal to be made.

  • German utilities have already arranged to fund BP’s move into wind farms in Morecambe Bay and the North Sea.
  • Norfolk’s gas terminal at Bacton is less than three hundred miles from Germany’s new hydrogen terminal at Wilhelmshaven.

The biggest loser could be Vlad the Poisoner.

Is There A Need For A Norfolk-Suffolk Interconnector?

The coast of East Anglia from the Wash to the Haven Ports of Felixstowe, Harwich and Ipswich is becoming the Energy Coast of England.

Starting at the Wash and going East and then South, the following energy-related sites or large energy users are passed.

Bicker Fen Substation

Bicker may only be a small hamlet in Lincolnshire, but it is becoming increasingly important in supplying energy to the UK.

Nearby is Bicker Fen substation, which connects or will connect the following to the National Grid.

  • The 26 MW Bicker Fen onshore windfarm.
  • The 1,400 MW interconnector from Denmark called Viking Link.
  • The proposed 857 MW offshore wind farm Triton Knoll.

This Google Map shows the location of Bicker Fen with respect to The Wash.

Bicker Fen is marked by the red arrow.

The Google Map shows the substation.

It must be sized to handle over 2 GW, but is it large enough?

Dudgeon Offshore Wind Farm

The Dudgeon offshore wind farm is a 402 MW wind farm, which is twenty miles off the North Norfolk coast.

  • It has 67 turbines and an offshore substation.
  • It is connected to the shore at Weybourne on the coast from where an underground cable is connected to the National Grid at Necton.
  • It became operational in Oct 2017.
  • Equinor and Statkraft are part owners of the windfarm and this is the home page of the wind farm’s web site.
  • Equinor is the operator of the wind farm.

This Google Map shows the location of Weybourne on the coast.

Note.

  1. Weybourne is in the middle on the coast.
  2. Sheringham is on the coast in the East.
  3. Holt is on the Southern edge of the map almost South of Weybourne.

This second map shows the location of the onshore substation at Necton, with respect to the coast.

Note.

  1. The Necton substation is marked by a red arrow.
  2. Holt and Sheringham can be picked out by the coast in the middle.
  3. Weybourne is to the West of Sheringham.
  4. Necton and Weybourne are 35 miles apart.

Digging in the underground cable between Necton and Weybourne might have caused some disruption.

Looking at Weybourne in detail, I can’t find anything that looks like a substation. So is the Necton substation connected directly to Dudgeon’s offshore substation?

Sheringham Shoal Offshore Wind Farm

The Sheringham Shoal offshore wind farm is a 316.8 MW wind farm, which is eleven miles off the North Norfolk coast.

  • It has 88 turbines and two offshore substations.
  • As with Dudgeon, it is connected to the shore at Weybourne on the coast.
  • But the underground cable is connected to an onshore substation at Salle and that is connected to the National Grid at Norwich.
  • It became operational in Sept 2012.
  • Equinor and Statkraft are part owners of the windfarm and this is the home page of the wind farm’s web site.
  • Equinor is the operator of the wind farm.

This second map shows the location of the onshore substation at Salle, with respect to the coast.

Note.

  1. The Salle substation is marked by a red arrow.
  2. Holt, Weybourne and Sheringham can be picked out by the coast in the middle.
  3. Weybourne is to the West of Sheringham.
  4. Salle and Weybourne are 13.5 miles apart.

Could the following two statements be true?

  • As the Sheringham Shoal wind farm was built first, that wind farm was able to use the shorter route.
  • It wasn’t built large enough to be able to handle the Dudgeon wind farm.

The statements would certainly explain, why Dudgeon used a second cable.

Extending The Dudgeon And Sheringham Shoal Wind Farms

Both the Dudgeon And Sheringham Shoal web sites have details of the proposed join extension of both wind farms.

This is the main statement on the Overview page.

Equinor has been awarded an Agreement for Lease by the Crown Estate, the intention being to seek consents to increase the generating capacity of both the Sheringham Shoal Offshore Wind Farm and the Dudgeon Offshore Wind Farm.

They then make three points about the development.

  • Equinor is proposing a joint development of the two projects with a common transmission infrastructure.
  • As part of the common DCO application, the Extension Projects have a shared point of connection at the National Grid Norwich Main substation.
  • These extension projects will have a combined generating capacity of 719MW which will make an important contribution to the UK’s target of 30GW of electricity generated by offshore wind by 2030.

This statement on the Offshore Location page, describes the layout of the wind farms.

The Sheringham Shoal Offshore Wind Farm extension is to the north and the east of the existing wind farm, while its Dudgeon counterpart is to the north and south east of the existing Dudgeon Offshore Wind Farm site. The proposed extension areas share the boundaries with its existing wind farm site.

They then make these two important points about the development.

  • Equinor is seeking to develop the extension project with a joint transmission infrastructure. A common offshore substation infrastructure is planned to be located in the Sheringham Shoal wind farm site.
  • The seabed export cable which will transmit the power generated by both wind farm extensions will make landfall at Weybourne.

There is also this map.

Note.

  1. The purple line appears to be the UK’s ten mile limit.
  2. The Sheringham Shoal Extension is outlined in red.
  3. The Dudgeon Extension is outlined in blue.
  4. The black lines appear to be the power cables.

I suspect the dotted blue lines are shipping routes sneaking their way through the turbines.

This statement on the Onshore Location page, describes the layout of the offshore and onshore cables.

A new seabed export cable will bring the electricity generated by both the Sheringham Shoal and Dudgeon Offshore Wind Farm extensions to shore at Weybourne, on the coast of Norfolk.

They then make these two important points about the development.

  • From there a new underground cable will be installed to transmit that power to a new purpose built onshore substation, which will be located within a 3km radius of the existing Norwich main substation, south of Norwich. This will be the National Grid network connection point for the electricity from both wind farm extensions.
  • The power will be transmitted from landfall to the substation using an HVAC system which eliminates the need for any relay stations along the onshore cable route.

There is also this map.

It will be a substantial undertaking to build the underground cable between Weybourne and South of Norwich.

Bacton Gas Terminal

The Bacton gas terminal is a complex of six gas terminals about ten miles East of Cromer.

  • It lands and processes gas from a number of fields in the North Sea.
  • It hosts the UK end of the BBL pipeline to The Netherlands.
  • It hosts the UK end of the Interconnector to Zeebrugge in Belgium.
  • The Baird and Deborah fields, which have been developed as gas storage, are connected to the gas terminal. They are both mothballed.

This Google Map shows the location of the terminal.

Note.

  1. The Bacton gas terminal is marked by a red arrow.
  2. Sheringham is in the North West corner of the map.
  3. Cromer, Overstrand, Trimingham and Mundesley are resort towns and villages along the coast North of Bacton.

This second map shows the Bacton gas terminal in more detail.

Would you want to have a seaside holiday, by a gas terminal?

Norfolk Boreas And Norfolk Vanguard

Norfolk Boreas and Norfolk Vanguard are two wind farms under development by Vattenfall.

  • Norfolk Boreas is a proposed 1.8 GW wind farm, that will be 45 miles offshore.
  • Norfolk Vanguard is a proposed 1.8 GW wind farm, that will be 29 miles offshore.

This map shows the two fields in relation to the coast.

Note.

  1. The purple line appears to be the UK’s ten mile limit.
  2. Norfolk Boreas is outlined in blue.
  3. Norfolk Vsnguard is outlined in orange.
  4. Cables will be run in the grey areas.

This second map shows the onshore cable.

Note.

  1. The cables are planned to come ashore between Happisburgh and Eccles-on-Sea.
  2. Bacton gas terminal is only a short distance up the coast.
  3. The onshore cable is planned to go from here across Norfolk to the Necton substation.

But all of this has been overturned by a legal ruling.

This article on the BBC is entitled Norfolk Vanguard: Ministers Wrong Over Wind Farm Go-Ahead, Says Judge.

These are the first four paragraphs.

A High Court judge has quashed permission for one of the world’s largest offshore wind farms to be built off the east coast of England.

The Norfolk Vanguard Offshore Wind Farm was granted development consent in July by the Secretary of State for Business, Energy and Industrial Strategy (BEIS).

But Mr Justice Holgate overturned the decision following legal action from a man living near a planned cable route.

A Department for BEIS spokeswoman said it was “disappointed by the outcome”.

I bet the spokeswoman was disappointed.

Vattenfall and the BEIS will go back to the drawing board.

But seriously, is it a good idea to dig an underground cable all the way across Norfolk or in these times build a massive overhead cable either?

Perhaps the solution is to connect the Norfolk Boreas And Norfolk Vanguard wind farms to a giant electrolyser at Bacton, which creates hydrogen.

  • The underground electricity cable across Norfolk would not be needed.
  • Bacton gas terminal is only a few miles up the coast from the cable’s landfall.
  • The UK gets another supply of gas.
  • The hydrogen is blended with natural gas for consumption in the UK or Europe.
  • A pure hydrogen feed can be used to supply hydrogen buses, trucks and other vehicles, either by tanker or pipeline.
  • Excess hydrogen could be stored in depleted gas fields.

The main benefit though, would be that it would transform Bacton gas terminal from a declining asset into Norfolk’s Hydrogen Powerhouse.

Great Yarmouth And Lowestoft

Great Yarmouth Outer Harbour and the Port of Lowestoft have not been the most successful of ports in recent years, but with the building of large numbers of wind farms, they are both likely to receive collateral benefits.

I wouldn’t be surprised to see the support ships for the wind farms switching to zero-carbon power, which would require good electrical connections to the ports to either charge batteries or power electrolysers to generate hydrogen.

Sizewell

Sizewell has only one nuclear power station at present; Sizewell B, but it could be joined by Sizewell C or a fleet of Small Modular Reactors (SMR).

The Sizewell Overhead Transmission Line

Sizewell also has a very high capacity overhead power line to Ipswich and the West.

I doubt, it would be possible to build an overhead transmission line like this today.

Sizewell And Hydrogen

EdF, who own the site are involved with Freeport East and may choose to build a large electrolyser in the area to create hydrogen for the Freeport.

East Anglia Array

The East Anglia Array will be an enormous wind farm., comprising up to six separate projects.

It will be thirty miles offshore.

It could generate up to 7.2 GW.

The first project East Anglia One is in operation and delivers 714 MW to a substation in the Deben Estuary, which connects to the Sizewell high-capacity overhead power line.

Most projects will be in operation by 2026.

Freeport East

As the Freeport develops, it will surely be a massive user of both electricity and hydrogen.

Problems With The Current Electricity Network

I don’t believe that the current electricity network, that serves the wind farms and the large energy users has been designed with the number of wind farms we are seeing in the North Sea in mind.

Every new windfarm seems to need a new connection across Norfolk or Suffolk and in Norfolk, where no high-capacity cables exist, this is stirring up the locals.

There is also no energy storage in the current electricity network, so at times, the network must be less than efficient and wind turbines have to be shut down.

Objections To The Current Policies

It is not difficult to find stories on the Internet about objections to the current policies of building large numbers of wind farms and the Sizewell C nuclear power station.

This article on the East Anglia Daily Times, which is entitled Campaigners Unite In Calling For A Pause Before ‘Onslaught’ Of Energy Projects ‘Devastates’ Region is typical.

This is the first paragraph.

Campaigners and politicians have called on the Government to pause the expansion of the energy industry in Suffolk, which they fear will turn the countryside into an “industrial wasteland” and hit tourism.

The group also appear to be against the construction of Sizewell C.

I feel they have a point about too much development onshore, but I feel that if the UK is to thrive in the future we need an independent zero carbon energy source.

I also believe that thousands of wind farms in the seas around the UK and Ireland are the best way to obtain that energy.

Blending Hydrogen With Natural Gas

Blending green hydrogen produced in an electrolyser  with natural gas is an interesting possibility.

  • HyDeploy is a project to investigate blending up to 20 % of green hydrogen in the natural gas supply to industrial and domestic users.
  • Partners include Cadent, ITM Power, Keele University and the Health and Safety Executive.
  • Natural gas naturally contains a small amount of hydrogen anyway.
  • The hydrogen gas would be distributed to users in the existing gas delivery network.

I wrote about HyDeploy in a post called HyDeploy.

Thje only loser, if hydrogen were to be blended with natural gas would be Vlad the Poisoner, as he’d sell less of his tainted gas.

An Interconnector Between Bicker Fen And Freeport East

I believe that an electricity interconnector between at least Bicker Fen and Freeport East could solve some of the problems.

My objectives would be.

  • Avoid as much disruption on the land as possible.
  • Create the capacity to deliver all the energy generated to customers, either as electricity or hydrogen.
  • Create an expandable framework, that would support all the wind farms that could be built in the future.

The interconnector would be a few miles offshore and run along the sea-bed.

  • This method of construction is well proven.
  • It was used for the Western HVDC Link between Hunterston in Scotland and Connah’s Quay in Wales.
  • Most wind farms seem to have existing substations and these would be upgraded to host the interconnector.

Connections en route would include.

Dudgeon Offshore Wind Farm

The interconnector would connect to the existing offshore substation.

Sheringham Shoal Wind Farm

The interconnector would connect to the existing offshore substation.

Dudgeon and Sheringham Shoal Extension Offshore Wind Farms

These two wind farms could be connected directly to the interconnector, if as planned, they shared an offshore substation in the Sheringham Shoal Extension offshore wind farm.

Bacton Gas Terminal

I would connect to the Bacton Gas Terminal, so that a large electrolyser could be installed at the terminal.

The hydrogen produced could be.

  • Stored in depleted gas fields connected to the terminal.
  • Blended with natural gas.
  • Exported to Europe through an interconnector.
  • Supplied to local users by truck or pipeline.

After all, the terminal has been handling gas for over fifty years, so they have a lot of experience of safe gas handling.

Norfolk Boreas And Norfolk Vanguard

These two wind farms could be connected directly to the interconnector, if they shared an offshore substation.

It would also help to appease and silence the objectors, if there was no need to dig up half of Norfolk.

Great Yarmouth And Lowestoft

It might be better, if these ports were supplied from the interconnector.

  • Either port could have its own electrolyser to generate hydrogen, which could be.
  • Used to power ships, trucks and port equipment.
  • Liquefied and exported in tankers.
  • Used to supply local gas users.
  • Hydrogen could be supplied to a converted Great Yarmouth power station.

Both Great Yarmouth and Lowestoft could become hydrogen hub towns.

Sizewell

This site has a high-capacity connection to the National Grid. This connection is a big eyesore, but it needs to run at full capacity to take electricity from the Energy Coast to the interior of England.

That electricity can come from Sizewell B and/or Sizewell C nuclear power stations or the offshore wind farms.

East Anglia Array

There would probably need to be a joint offshore substation to control the massive amounts of electricity generated by the array.

Currently, the only wind farm in operation of this group is East Anglia One, which uses an underground cable connection to the Sizewell high-capacity connection to the Bullen Lane substation at Bramford.

Freeport East, Ipswich And Bullen Lane Substation

This Google Map shows the area between Ipswich and the coast.

Note.

  1. Sizewell is in the North-East corner of the map.
  2. Felixstowe, Harwich and Freeport East are at the mouth of the rivers Orwell and Stour.
  3. The Bullen Lane substation is to the West of Ipswich and shown by the red arrow.

I would certainly investigate the possibility of running an underwater cable up the River Orwell to connect the Southern end of the interconnector Between Bicker Fen And Freeport East.

This Google Map shows the Bullen Lane Substation.

It looks impressive, but is it big enough to handle all the electricity coming ashore from the offshore wind farms to the East of Suffolk and the electricity from the power stations at Sizewell?

Conclusion

I believe there are a lot of possibilities, that would meet my objectives.

In addition, simple mathematics says to me, that either there will need to be extra capacity at both Bicker Fen and Bullen Lane substations and onward to the rest of the country, or a large electrolyser to convert several gigawatts of electricity into hydrogen for distribution, through the gas network.

ITM Power’s 24MW Electrolyser Sale to Yara

The title of this post, is the similar to that of this press release from ITM Power. I just added a few words.

These are the first three paragraphs.

ITM Power (AIM: ITM), the energy storage and clean fuel company, is pleased to provide details of the sale of a 24MW electrolyser to Linde Engineering contained in the Company’s Half Year Report issued yesterday. The electrolyser is to be installed at a site operated by Yara Norge AS (“Yara”) located at Herøya outside Porsgrunn, about 140 km southwest of Oslo. The site covers an area of approximately 1.5 square kilometres and is the largest industrial site in Norway. The Porsgrunn site produces 3 million tons of fertiliser per year.

The hydrogen required for ammonia production is currently produced from SMR. Yara intends to start replacing this grey hydrogen with green hydrogen produced from renewable energy and electrolysis. The 24MW system supplying 10,368 kg/day of hydrogen will account for approximately 5% of the plant’s consumption and serve as a feasibility study for future upscaling. Yara has received a grant of up to NOK 283m (£23.6m,pending ESA approval) from Enova SF, a Government funding body, to invest in green solutions for hydrogen used for industrial purposes in Norway.

The electrolyser equipment is due to be ready for shipment from ITM Power in Q4 2022 with revenue realised in the Company’s 2022/2023 financial year.

These are my thoughts.

The Size Of The Electrolyser

A 24 MW electrolyser, that produces 10,368 Kg of hydrogen/day may sound a large device.

This is an extract from the press release.

In January 2021, the Company received an order for the world’s then largest PEM electrolyser of 24MW from Linde. In October 2021, the Company, with Linde, announced the deployment of a 100MW electrolyser at Shell’s Rhineland refinery, following the start-up of an initial 10MW facility at the site.

It appears that ITM Power have built one before and one four times the size has been ordered.

What Size Of Electrolyser Would Yara Need To Fully Decarbonise Ammonia Production?

According to the press release, a 24 MW electrolyser will produce five percent of the plant’s consumption, which means that a 480 MW electrolyser will be needed, if Yara use an ITM electrolyser to produce all their hydrogen.

Will manufacture of an electrolyser of this size be a problem for ITM Power?

The press release says this about electrolyser production.

ITM Power operates from the world’s largest electrolyser factory in Sheffield with a capacity of 1GW (1,000MW) per annum, with the announced intention to build a second UK Gigafactory in Sheffield with a capacity of 1.5GW expected to be fully operational by the end of 2023. The Group’s first international facility, expected to have a capacity of 2.5GW per annum, is intended to be operational by the end of 2024, bringing total Group capacity to 5GW per annum.

It also says that the company has raised £250m to accelerate expansion.

The Delivery Date

The delivery date of the electrolyser is stated as Q4 2022.

I find this rather quick, which makes me believe that one of the reasons for the success of ITM Power is their production process.

How Much Ammonia Is Produced Worldwide?

This is an extract from this publication from the Royal Society, which is entitled Ammonia: Zero-Carbon Fertiliser, Fuel And Energy Store.

Current global ammonia production is about 176 million tonnes per year and is predominantly achieved through the steam reforming of methane to produce hydrogen to feed into ammonia synthesis via the Haber Bosch process.

Ammonia production is a highly energy intensive process consuming around 1.8% of global energy output each year (steam methane reforming accounts for over 80% of the energy required) and producing as a result about 500 million tonnes of carbon dioxide (about 1.8% of global carbon dioxide emissions)2,3,4. Ammonia synthesis is significantly the largest carbon dioxide emitting chemical industry process. Along with cement, steel and ethylene production, it is one of the ‘big four’ industrial processes where a decarbonisation plan must be developed and implemented to meet the netzero carbon emissions target by 2050.

It looks like Linde and ITM Power have a fairly simple plan to decarbonise world ammonia production. And they have started with one of the easier targets; Yara in the very environmentally-correct Norway.

I estimate that to produce 176 million tonnes of green ammonia will need over 28 GW of electrolyser capacity.

Conclusion

If Linde and ITM Power can persuade the world, that their technology is the way to go, then they’ve got it made.

French City Cancels Purchase Of 51 Hydrogen Buses After Realising Electric Ones Would Be Six Times Cheaper To Run

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

The city is Montpelier and it’s their decision, but I do find it strange, that the French city of Pau have chosen the hydrogen version of the the Van Hool ExquiCity bus.

But Pau have chosen a British hydrogen system from ITM Power, rather than a French one.

Catalyst Capital Makes First Move In GBP 300m Battery Storage Strategy

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

This is the first paragraph.

Fund manager Catalyst Capital has acquired a site to build a 100-MW battery in Yorkshire, northern England, in the first of a series of planned deals under a GBP-300-million (USD 406.1m/EUR 358.9m) strategy to develop diversified UK battery energy storage systems (BESS) facilities.

£300 million, says to me that the finance industry, now finds battery storage to be a worthwhile investment.

Skelton Grange Power Station

This Google Map shows the location of the Skelton Grange power station site, where the battery will be developed.

And this second Google Map shows the site in more detail.

Note that there is still a sub-station on the site.

The article states that planning permission was received in 2021 and they hope to have the facility on-line in the first quarter of this year.

That appears quick to me. Is it because the electrical connection already in situ?

It should also be noted, that the battery output of 100 MW is much less than that of the former coal-fired power station in the mid-1980s, which was at last 480 MW.

I also wonder, if the site could host a hydrogen fuelling station for buses.

  • It is not far from the centre of Leeds.
  • It has a good connection to the National Grid.
  • An electrolyser like the one built by ITM Power at Tyseley Energy Park uses 3 MW of electricity to produce around 1.5 tonnes of hydrogen per day.

I also feel that the site could host a wind turbine up to about 10 MW.

Conclusion

Catalyst Capital seems to have made a big entry into the market. They won’t be the last to do this, as the returns are there and the battery storage is needed.

Riding Birmingham’s New Hydrogen-Powered Buses

I went to Birmingham today and took one of their new hydrogen buses on route 51 to Perry Barr and another one back.

Note.

  1. As the pictures show Perry Barr is a bit of traffic bottleneck because of the reconstruction of Perry Barr station an other developments in the area, because of the Commonwealth Games, which are going to e held in Birmingham in 2022.
  2. The route goes past the High Speed Two site.
  3. Birmingham is a city of highways, flyovers, underpasses and roundabouts.
  4. The buses have wi-fi and charging points for phones.

I very much feel that the buses are the best hydrogen-powered vehicles, that I’ve travelled in, as they are smooth, comfortable, quiet and seem to have excellent performance.

Birmingham Buses Have Their Own Hydrogen Electrolyser

London bring their hydrogen in by truck from Runcorn, where it is created by electrolysis, for their hydrogen-powered buses.

On the other hand, Birmingham Buses have their own electrolyser at the Tyseley Energy Park.

This Google Map shows Tyseley Energy Park.

Note.

  1. The Birmingham Bus Refueler hadn’t opened, when this map was last updated.
  2. Tyseley Energy Park is only a few miles from the City Centre and route 51.
  3. I estimate that the Tyseley Energy Park occupies around four hectares.

This page on the Tyseley Energy Park web site described the refuelling options that are available.

  • Fuels available include hydrogen, biomethane, compressed natural gas, diesel, gas oil and AdBlue.
  • There are a range of charging options for electric vehicles.

The 3 MW electrolyser was built by ITM Power of Sheffield, which I estimate will produce nearly 1.5 tonnes of hydrogen per day.

According to this page on the Wrightbus website, a hydrogen-powered double-deck bus needs 27 Kg of hydrogen to give it a range of 250 miles. The refuelling of each bus takes eight minutes.

So the current fleet of twenty buses will need 540 Kg of hydrogen per day and this will give them a combined range of 5000 miles.

It would appear that the capacity of the electrolyser can more than handle Birmingham’s current fleet of twenty buses and leave plenty of hydrogen for other vehicles.

Could Other Towns And Cities Build Similar Energy Parks?

I don’t see why not and it looks like ITM Power are involved in a proposal to build an electrolyser at Barking.

Some would feel that London ought to follow Birmingham and create its own hydrogen.

National Express Deploys Hydrogen Double-Deckers In The West Midlands

The title of this post, is the same as that of this article on Renewable Energy Magazine.

This is the first paragraph.

National Express has deployed 20 hydrogen double-decker buses purchased by Birmingham City Council, serving West Midlands route 51 to Walsall via Perry Barr from 6th December 2021– the only hydrogen buses operating in England outside London.

The buses are from Wrightbus.

The article also says this about the source of the hydrogen.

The council are also collaborating with ITM, who are producing and dispensing the hydrogen fuel from the new re-fuelling hub at Tyseley Energy Park.

This is surely the way to do it. Hydrogen buses with a local source of freshly-picked hydrogen.
