Utility Completes Testing Of Revolutionary Zero-Electricity Hydrogen Reactor
The title of this post, is the same as that of this article on Hydrogen Central.
These two paragraphs introduce the article.
Utility completes testing of revolutionary zero-electricity hydrogen reactor.
Utility announced at its 3rd annual technology day event, the successful completion of their pilot plant testing program for the H2Gen™ reactor product line. Utility is the only decarbonization technology company pioneering the eXEROTM technology platform optimized for hard to abate industry sectors.
Am I right in thinking, that Utility have developed a way of splitting hydrogen out of hydrocarbons by cleverly exploiting physics and chemistry?
This is the first paragraph on their Learn More page.
The Electroless Coupled Exchange Reduction Oxidation technology platform (eXERO™) capitalizes on both the advantages of electrochemical processes (which yield high product purity without the need for expensive purification steps) and chemical processes (which have comparatively low capital and operating costs, especially avoiding the losses of electricity generation and transmission). The eXERO™ technology platform is achieved by removing the external electrical circuit from an electrolyzer and instead driving the electrolysis reaction with the overpotential (voltage) that exists between different gas compositions. Similar to a conventional solid oxide electrolyzer, oxygen ions are transferred from the cathode to the anode through an oxygen ion conducting electrolyte. However, unlike a conventional electrochemical reactor, electrons are transferred from the anode to the cathode through an electronically conducting phase within the electrolyte, also known as a mixed conducting electrolyte.
In a section on the page, with a heading of Principles, this is said.
The eXERO™ technology platform is based on two streams which are separated by an impermeable electrolyte, and counter-exchange of oxygen ions and electrons. Thus, one of the streams undergoes reduction while the other stream simultaneously undergoes oxidation. Unlike traditional fuel cells or electrolyzers, no current is extracted or delivered to the reactor to drive the process. Rather, an overpotential can be induced by introducing gases of different composition at the anode and cathode the cell. Examples of gases introduced at the anode to induce an overpotential, relative to steam (water) are shown below:
This is interesting. Very interesting!
Dutch Take Aim At Lower Green Hydrogen Costs By Combining Offshore Wind And Floating Solar
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
A consortium of Dutch companies has launched a government-backed project to explore the synergies between offshore wind, offshore solar and hydrogen production at sea for improved sustainability of North Sea renewable energy projects.
T thought about calling this post, The Dutch Go For The Full Monty, but there is no mention of wave or tidal power.
These two paragraphs outline the project.
The four-year project, dubbed Solar Enhanced North Sea Energy Hub (SENSE-HUB), is expected to accelerate the rollout of offshore solar into offshore renewable energy systems.
Let by TNO, short for Netherlands Organization for Applied Scientific Research, the project will address the integration of various energy system modules for the Dutch North Sea by understanding and removing the implementation barriers for future SENSE-HUBs from a technical, economical, ecological, legal and societal perspective.
I wouldn’t be surprised to see more integrated systems like this in the waters around our coasts.
I also believe that the ultimate offshore energy production system will also use wave and tidal power to generate electricity and have inbuilt energy storage.
Preparing For Take-Off: Aviation Embraces Clean Hydrogen
The title of this post, is the same as that, of this article on Ryse Hydrogen.
These three paragraphs introduce the article.
Aviation’s clean hydrogen revolution is coming from all directions.
Taking a bottom-up approach, start-ups such as ZeroAvia are developing technology to convert small aircraft to hydrogen fuel, while at the other end of the spectrum, industry giants such as Airbus and Rolls-Royce are exploring how they can carry hundreds of passengers 1,000s of miles across the world.
The timescales for these projects are very different but progress is visible for both approaches.
The last two paragraphs are optimistic.
Hydrogen fuel could make up 32% of the market by 2050 if it becomes commercially available by 2035, according to a study from climate think-tank Energy Transition Commission.
It would seem that it’s only a matter of time before truly clean air travel is cleared for take-off and hydrogen-powered aircraft are carrying passengers and cargo across the skies.
The article is a good summary of the state of zero-carbon hydrogen-powered aircraft. Read it!
Racing Towards A Green Future
The title of this post, is the same as that of this article on Ricardo.
This is the first paragraph.
While Formula E and its sibling electric race series, Extreme E and RX2e, are burnishing battery-powered vehicles credentials, motorsport from Formula 1 down is actively pursuing how traditional internal combustion engine (ICE) race and rally cars can be made more environmentally acceptable.
The article, which is a must-read, then describes the various routes and options, that motorsport is taking towards zero-carbon.
The article finishes with this paragraph.
While motorsport technology can, and does, transfer to production cars, especially in the higher echelons, whether the path it is beating on AS fuels will convince legislators that battery electric vehicles are only an answer rather than the answer remains to be seen.
I believe that when an affordable small hatchback powered by hydrogen hits the road as it inevitably will, it will have Ricardo’s fingerprints all over it.
Coal Sales Could Lose Tens Of Millions For Consumers
The title of this post, is the same as that of this article on The Times.
These two paragraphs outline the story.
A huge stockpile of coal bought for emergency use in power stations this winter is due to be resold at a loss of tens of millions of pounds to consumers.
National Grid funded the procurement of hundreds of thousands of tonnes of coal as part of a deal to keep open five coal-fired units this winter. The estimated £368 million cost of the “winter contingency contracts”, which includes an undisclosed sum for the coal purchases, is being recouped via energy bills.
Note.
- None of the coal has been burned, as the weather was warmer than expected,
- It is now sitting in various places around the country.
- It will probably sell at a loss and there will be transport costs.
I will look at the mathematics of disposal.
Burning Fossil Fuels
On the Internet, I have found these figures.
- If you burn a kilogram of natural gas you create 15.5 KWh of electricity and 2.75 kilograms of carbon dioxide.
- If you burn a kilogram of coal you create 2.46 KWh of electricity and 2.38 kilograms of carbon dioxide.
This means that natural gas and coal create 0.18 and 0.97 kilograms of carbon dioxide respectively for every KWh generated.
I believe these figures say, that if we have to use a fossil fuel, gas will be much better than coal for climate change reasons.
The Size Of The Problem
We are talking about 130,000 tonnes of coal for EDF and 400,000 for Drax. Uniper’s figure is not stated. Let’s say they make the coal pile up to 600,000 tonnes.
Burning this pile will generate 1,476,000 KWh or 1.476 GWh of electricity and create 1428,000 tonnes of carbon dioxide.
Effect On Total UK Carbon Dioxide Emissions
According to government figures on the Internet in 2021 we emitted 107.5 million tonnes of carbon dioxide.
Burning all that coal in a year, would add less than 1.5 % to our carbon dioxide emissions. Perhaps we should burn it strategically over a number of years, when there are energy supply problems, as it is after all a crude form of energy storage.
What Would I Do With The Savings?
The money saved on the transport and making loss-making sales could be spent on other ways to save carbon emissions, like converting surplus wind energy into hydrogen and blending it with the gas.
I discussed the mathematics of hydrogen blending in UK – Hydrogen To Be Added To Britain’s Gas Supply By 2025.
If we put 2 % hydrogen in our natural gas, this would save nearly 2.5 million tonnes of carbon dioxide emissions in a year. This figure is much bigger than the 1428,000 tonnes of carbon dioxide, that would be created by burning all the coal.
At a level of 2 %, most appliances, boilers and industrial processes would work without change. But a good service would help.
UK – Hydrogen To Be Added To Britain’s Gas Supply By 2025
The title of this post, is the same as that of this article on Hydrogen Central.
These are the first three paragraphs.
Hydrogen to be added to Britain’s gas supply by 2025.
Hydrogen is to be pumped into Britain’s main gas pipeline by 2025 as part of a scramble to ditch fossil fuels and move to net zero.
Between 2% and 5% of the fuel flowing through the country’s transmission network will be hydrogen in two years under plans drawn up by National Gas, which owns the pipelines.
Note.
- The article says that.on a winter’s day, you’ve got seven times more energy going through the gas network than the electricity network.
- Between 2% and 5% of hydrogen, would be unlikely to mean that appliances, boilers and industrial processes would need to be changed.
- I suspect that domestic appliances and boilers would just need a good service.
- HyDeploy has shown that 20 % of hydrogen could be possible.
- The hydrogen could be added, where the natural gas enters the UK gas network.
The exercise would save a lot of carbon emissions.
How Much Electricity Would Be Needed To Create The Hydrogen?
In The Mathematics Of Blending Twenty Percent Of Hydrogen Into The UK Gas Grid, I calculated the amount of hydrogen that would be needed for 20 %, how much electricity it would need and how much carbon dioxide would not be emitted.
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 6,030,142.498 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 Much Electricity Would Be Needed To Create The Hydrogen for a 5 % Blend?
I’ll now repeat the calculation for a 5 % blend,
How Much Hydrogen Needs To Be Added?
I will now calculate the weight of hydrogen needed to be added.
- UK gas consumption rounds to 79161.7 million cubic metres.
- Five percent is 3958.085 million cubic metres.
- A cubic metre of hydrogen weighs 0.082 Kg, which gives that in a year 324.56297 million kilograms will need to be added to the UK gas supply.
This is 324,563 tonnes per year, 889.21 tonnes per day or 37 tonnes per hour.
How Much Electricity Is Needed To Create This Amount Of Hydrogen?
Earlier I said this.
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 37 tonnes per hour of hydrogen would need 2,045.16 MW of electricity or just over 2 GW.
How Much Carbon Dioxide Would Be Saved?
Earlier, I found that a Kg of methane will produce 2.75 Kg of carbon dioxide on combustion.
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 five percent will be replaced by hydrogen, carbon dioxide emission savings will be 6030,142.4975 tonnes.
The UK would also reduce natural gas consumption by five percent or 3958.085 million cubic metres per year.
How Much Electricity Would Be Needed To Create The Hydrogen for a 2 % Blend?
I’ll now repeat the calculation for a 2 % blend,
How Much Hydrogen Needs To Be Added?
I will now calculate the weight of hydrogen needed to be added.
- UK gas consumption rounds to 79161.7 million cubic metres.
- Two percent is 1,583.234 million cubic metres.
- A cubic metre of hydrogen weighs 0.082 Kg, which gives that in a year 129.825 million kilograms will need to be added to the UK gas supply.
This is 129,825 tonnes per year, 355.68 tonnes per day or 14.8 tonnes per hour.
How Much Electricity Is Needed To Create This Amount Of Hydrogen?
Earlier I said this.
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 14.8 tonnes per hour of hydrogen would need 817 MW of electricity or not even a GW.
How Much Carbon Dioxide Would Be Saved?
Earlier, I found that a Kg of methane will produce 2.75 Kg of carbon dioxide on combustion.
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 two percent will be replaced by hydrogen, carbon dioxide emission savings will be 2,412,057 tonnes.
The UK would also reduce natural gas consumption by two percent or 1,583.234 million cubic metres per year.

Ballymena: Wrightbus To Develop Hydrogen Production Facility
The title of this post, is the same as that of this article on the BBC.
This is the sub-heading.
Wrightbus is planning to develop a green hydrogen production facility at its factory in Ballymena.
And these first three paragraphs outline the project.
The proposal is being made in partnership with a sister company, Hygen Energy.
Part of the Wrightbus business is the manufacturing of hydrogen-powered buses, some of which are operated by Translink.
The new facility would help create a reliable source of fuel for those buses and other hydrogen-powered vehicles.
It seems a well-designed project and it appears Hygen are building a similar facility in Bradford.
Some months ago, I had a drink in my house, with three senior London bus company executives.
One has had problems with electric buses, as getting the required power to charge a fleet in some Central London garages is not easy.
I showed them these figures, from the Wrightbus web site.
- A Wrightbus electric double-decker takes 2.5 hours to charge for a 200 mile range.
- A hydrogen double-decker takes 8 minutes to refuel with up to a 280 miles range.
They were impressed. Especially, as a typical duty for a bus in London is almost 200 miles. A hydrogen bus seemed to make a lot more sense.
So why isn’t London preparing for scores of hydrogen buses?
Ask the Mayor!
Riding On Hydrogen-Powered Buses And Trains
These posts describe my trips on hydrogen-powered buses
Note.
- The first bus starts from Birmingham City Centre.
- The second bus runs between Paddington station and John Lewis in Oxford Street in London.
This post describes my first ride in a hydrogen-powered train.

This was through the German countryside between Hamburg and Cuxhaven.
Mersey Tidal Project And Where It Is Up To Now
The title of this post, is the same as that of this article on the Liverpool Echo.
This is the sub-heading.
With a major agreement on the project reached this week, we take a look at what it all means.
There is a section, which is called So What Is A Mersey Tidal Project?, where this is said.
The idea is to build a huge damn structure in the River Mersey with turbines that can harness energy from the tides of the river and convert it into clean power. The city region combined authority is hopeful that this could power up to 1 million homes and create thousands of local jobs
The city region has one of the country’s largest tidal ranges so it is seen as a perfect opportunity to explore a tidal project here. It is hoped such a project could generate a ‘plentiful, reliable supply of clean, green energy for generations to come.
In the 1970s, I did a small project management consultancy at Frederick Snow and Partners in London. They showed me their ambitious plans for a Severn Barrage, which was a tidal scheme, that would have created a tenth of our electricity and would have cost around a billion pounds.
But Harold Wilson, who was Prime Minister at the time, felt that the money would be better spent on building massive coal-fired power stations, rather than building a clean power station, that would last centuries.
A second section is called What Happened This Week?, where this is said.
This week the Liverpool City Region signed an agreement with the company behind the current world’s current largest tidal project with a view to learning lessons.
The Sihwa Lake tidal range power plant, which is operated by Korea Water Resources Corporation, generates 552GWh of clean, green energy every year, replacing the equivalent of 862,000 barrels of oil a year.
Jeong Kyeong Yun, Vice President of Korea Water Resources Corporation, known as K-water, was in Liverpool this week to sign an historic Memorandum of Agreement with Mayor Rotheram. It is hoped the agreement will pave the way for close co-operation between the two tidal power projects, through reciprocal visits and information sharing.
Note.
- The Liverpool Echo is still making spelling mistakes, like damn instead of dam. In the 1960s, Fritz Spiegl used to give us all pleasure by writing about them.
- 552 GWh would keep the UK powered up for nearly a month.
- The Sihwa Lake Tidal Power Station has a comprehensive Wikipedia entry.
- The Sihwa dam has a road over the top.
- Unlike Frederick Snow’s scheme for the Severn, Sihwa only generates power, on the incoming tide. But it does generate 254 MW.
As ever, Liverpool is thinking big and getting the experience from those, who know what they are doing.
This last paragraph, gives the thoughts of the Mayor.
Mayor Rotheram said that with the right support, he hopes the project could be generating clean, renewable power by the end of this decade.
I would go along with that.
The Mersey Tidal Project And The Mersey Gateway Bridge
Frederick Snow’s plans for the Severn could have incorporated a new road and rail crossing of the estuary.
This Google Map shows the the Sihwa Lake Tidal power station.
The road over the dam is clearly visible.
I took these pictures of the Mersey Estuary as I came back from Liverpool on Tuesday.
This Google Map shows the Mersey Estuary.
Note.
- The River Mersey flowing from the North-East corner of the map to the South-West corner.
- On the South Bank of the Mersey, there is the deep-water channel of the Manchester Ship Canal.
- The bridge in the North-East corner of the map is the Mersey Gateway Bridge.
- Then there is the pair of bridges at Runcorn; the Silver Jubilee Bridge and the Runcorn Railway Bridge.
I am fairly sure, that the Mersey Tidal Project would be built downstream of the pair of bridges at Runcorn.
This Google Map shows the Mersey Estuary from the Runcorn Bridges to the mouth of the Manchester Ship Canal.
Note.
- The Mersey Gateway Bridge and the two Runcorn bridges are in the North-East corner.
- The route of the Manchester Ship Canal is clearly visible.
- Liverpool John Lennon Airport is on the North Bank of the Mersey.
- The M56 and M53 Motorways run East-West across the map to the South of the River.
This map leads me to the conclusion, that a tidal barrage with a road on top could link Liverpool to the M56.
I have some thoughts.
Rail Access To Liverpool
There is an electrified railway between Liverpool and Ellesmere Port.
- The railway can be picked out running across the bottom of the map.
- In Liverpool’s Vision For Rail, I talked about Liverpool City Region’s plan to expand this service to Helsby, Frodsham and Runcorn East.
- Helsby and Frodsham are shown on the map.
I wouldn’t be surprised to see a new Park-and-Ride station, where the M56 and the railway cross.
Ship Access To Manchester And Other Ports
Barrages usually have to provide access for ships to pass through to any ports behind the barrage.
But the Mersey Tidal Project already has that access. – It was built in the 1893 and is called the Manchester Ship Canal.
There is probably strong protection between the Mersey and the Canal between the mouth of the Canal and Runcorn, which may impact positively on the costs of the barrage.
The Simple Barrage
Sihwa Lake Tidal power station is a simple barrage with a bridge over the power station in the middle.
This Google Map shows the location of the power station.
Note.
- Seoul is in the North-East corner of the map.
- The Sihwa Lake Tidal power station is marked by the red arrow.
This Google Map shows a close-up of the power station.
Note.
- The ten turbines appear to be in the gap.
- There appears to be a road on top of the barrage.
- The area to the West of the power station is marked as a rest area.
- A Moon Observatory is marked.
- It has bus stops, showing that it is served by the 123 and 123-1 buses.
It is an impressive structure.
I’m sure that this type of barrage would work over the Mersey.
- A road could be built on top.
- It may only be able to generate electricity,from an incoming tide, like Sihwa.
- It could incorporate a rest area.
I do suspect though Liverpudlians would add a few unique touches of their own. Perhaps some liver birds or superlambananas.
The Frederick Snow Solution
The Severn is a wide river and he proposed that there would be a dam across the river, with a spine running East along the middle of the river.
- The spine would divide the river into two lakes.
- On the incoming tide, sluices would open and allow water to flow into the Northern or high lake from the Mersey estuary.
- On the outgoing tide, sluices would open and allow water to flow out of the Southern or low lake into the Mersey estuary.
- Water would flow between the high and low lake through turbines to generate electricity.
- I have assumed that the high lake is on the North side, but if the geography is more suitable, the high and low lakes could be reversed.
In the design for the Severn Barrage, an International airport would have been built on the spine.
But Liverpool already has a nearby International airport, so perhaps it could be much better to install a large electrolyser and hydrogen storage on the spine.
BMW To Launch Small Test Fleet Of H2 Cars To Use Truck Hydrogen Fuel Stations
The title of this post, is the same as that of this article on Hydrogen Fuel News.
This is the first paragraph.
BMW is aiming to take a ride on the network of hydrogen fuel stations for trucks in order to help overcome the challenge associated with building an expensive network specifically for passenger cars.
Why not?
