Good Vibrations Turbo Charge Green Hydrogen Production
The title of this post, is the same as this news item from RMIT University in Australia.
This is the sub-heading.
Engineers in Melbourne have used sound waves to boost production of green hydrogen by 14 times, through electrolysis to split water.
And these are the first two paragraphs.
They say their invention offers a promising way to tap into a plentiful supply of cheap hydrogen fuel for transportation and other sectors, which could radically reduce carbon emissions and help fight climate change.
By using high-frequency vibrations to “divide and conquer” individual water molecules during electrolysis, the team managed to split the water molecules to release 14 times more hydrogen compared with standard electrolysis techniques
I could understand a two or three times increase, but fourteen times is sensational.
Again, Australia seems to have found the gold through innovative green technology.
Other Benefits
Read the last sections of the news item.
- The process allows the use of cheaper silver electrodes instead of platinum and iridium.
- The engineers also feel that their technique could help in this and other process where bubbles are a problem.
Sound waves have been used for decades for various processes and I am surprised that this appears to be the first time, they’ve applied to electrolysis.
Conclusion
I worked in a hydrogen factory around 1970 and have watched developments over the years.
I am now convinced that an individual or a company will come up with an affordable way to make green hydrogen.
Promising technologies in addition to this one include.
- High Temperature Electrolysis. See Nuclear-Enabled Hydrogen – How It Helps To Reach Net Zero.
- HiiROC See Centrica Partners With Hull-Based HiiRoc For Hydrogen Fuel Switch Trial At Humber Power Plant.
- Electrolysis of sea water. See Torvex Energy.
I can see a combination of a couple of methods.
SSE Thermal Charts Path To Green Hydrogen Future With First-Of-A-Kind Project
The title of this post, is the same as that of this press release from SSE Thermal.
This is the sub-heading.
SSE Thermal is developing a first-of-a-kind project in the Humber which would unite hydrogen production, storage and power generation in one location by the middle of this decade.
These paragraphs explain the project.
The Aldbrough Hydrogen Pathfinder project will support the evidence base for wider deployment of flexible hydrogen power in the UK’s net zero journey and is a major enabler of SSE Thermal’s wider Humber ambitions.
Located at SSE Thermal and Equinor’s existing Aldbrough Gas Storage site on the East Yorkshire coast, the project is designed to demonstrate the interactions between hydrogen electrolysis, hydrogen cavern storage and 100% hydrogen dispatchable power.
The concept would see green power sourced from grid through Renewable PPAs, in compliance with the Low Carbon Hydrogen Standard. Hydrogen would then be produced via a 35MW electrolyser before being stored in a converted salt cavern and then used in a 100% hydrogen-fired turbine, exporting flexible green power back to grid at times of system need. In future, hydrogen storage will also benefit offtakers in other sectors, for example in industry, heat or transport.
Note.
- The Aldbrough Gas Storage site currently can store the equivalent of 320 GWh of electricity, It is currently being expanded to be one of the largest hydrogen stores in the world according to this page on the SSE web site.
- SSE Thermal are proposing to build a hydrogen-powered power station at Keadby to the South of the Humber. The press release says this power station could have a peak demand of 1,800MW of hydrogen.
- Aldbrough at its current size could keep the Keadby hydrogen-powered power station going for a week. But Aldbrough will be a lot bigger than the current 320 GWh.
- The Hornsea and Dogger Bank wind farms off the coast of East Yorkshire will have a capacity of at least 13.5 GW.
- A 35 MW electrolyser will produce 15.2 tonnes of hydrogen per day.
SSE and Equinor hope to be storing hydrogen by 2025.
Conclusion
It is an enormous project and it will surely grow with more electrolysers and hydrogen-powered power stations.
Ramboll To Develop Offshore Wind-To-Hydrogen Concept
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Ramboll has been selected to investigate the feasibility of producing hydrogen offshore at a multi-gigawatt scale with NortH2 in the Dutch part of the North Sea.
Note.
- NortH2 has a web site.
- There is a very rich About NortH2 page.
- NortH2 is a consortium made up of Equinor, Eneco, Gasunie, Groningen Seaports, RWE and Shell Netherlands.
- The consortium aims to use 4 GW to produce hydrogen by 2030 and 10 GW by 2040.
The world needs more ambitious projects like this.
Electrolyser System To Linde For Green Hydrogen Production In Niagara Falls, New York
The title of this post, is the same as that of this press release from Cummins.
This is the first paragraph.
Cummins Inc. will supply a 35-megawatt (MW) proton exchange membrane (PEM) electrolyzer system for Linde’s new hydrogen production plant in Niagara Falls, New York. Once commissioned, Cummins’ electrolyzer system will power Linde’s largest green hydrogen plant in the U.S., marking significant progress in moving the green hydrogen economy forward.
Note.
- The electrolyser will be powered by hydroelectricity.
- Linde have a strategic investment in iTM Power, who are a British manufacturer of electrolysers.
- ITM Linde Electrolysis is a joint venture between iTM Power and Linde.
Why did Linde choose Cummins over iTM Power?
Is it down to cost, delivery, politics or quality?
Hydrogen Corolla Cross Begins Testing In Japan
The title of this post, is the same as that of this article on Toyota UK Magazine.
These two introductory paragraphs outline Toyota’s plans for hydrogen.
Toyota’s approach to carbon neutrality is to develop and offer multiple technologies to support widely varying customer needs and market environments around the world. This multi-technology approach – which includes battery electric and fuel cell electric and plug-in hybrid electric and hybrid electric vehicles – is witnessed in the company’s development of a new hydrogen car powered by a hydrogen combustion engine.
Toyota firmly believes it is too early to focus on a single zero-emission solution and is therefore concurrently developing hydrogen fuel cell and hydrogen combustion technology alongside battery electric technology. Today’s announcement follows last week’s confirmation that Toyota Motor Manufacturing UK will lead a consortium developing a hydrogen fuel cell version of the Hilux pick-up at its Burnaston car plant in Derbyshire.
This paragraph gives more details of the car.
This version of the mid-size Corolla SUV* is powered by the 1.6-litre, three-cylinder turbocharged engine featured in the GR Corolla* performance model, re-engineered with high-pressure hydrogen direct injection technology. The prototype is also fitted with hydrogen fuel tanks, packaged with know-how gained from the development of the Toyota Mirai fuel cell electric saloon. The prototype is able to accommodate five passengers and their luggage. Real-world evaluation is being carried out alongside digital development, and the vehicle will soon undergo winter testing in northern Japan.
I must admit, that if I still drove, this type of vehicle with a hydrogen internal combustion engine, would be what I’d buy.
Increased CCS Can Decarbonise GB Electricity Faster On Route To Net Zero
The title of this post, is the same as that of this news item on the SSE web site.
This is the first paragraph.
Building more power carbon capture and storage plants (Power CCS) could significantly accelerate the UK’s plans to decarbonise the GB electricity system on route to net zero, according to new analysis commissioned by SSE.
I am not surprised, as in my time, I have built several production, storage and distribution mathematical models for products and sometimes bringing things forward has beneficial effects.
These three paragraphs summarise the findings.
The UK Government’s proposed emissions reductions from electricity for 2035 could be accelerated to 2030 by combining its 50GW offshore wind ambition with a significant step up in deployment of Power CCS. This would require 7-9GW (equivalent to 10-12 plants) of Power CCS compared to the current commitment of at least one Power CCS plant mid-decade, according to experts at LCP Delta.
Replacing unabated gas with abated Power CCS generation will deliver significant reductions in greenhouse gas emissions. The analysis suggests that adding 7-9GW Power CCS to the UK’s 2030 offshore wind ambition will save an additional 18 million tonnes of CO2 by 2040, by preventing carbon emissions during periods when the sun isn’t shining, and the wind isn’t blowing.
Gas consumption for electricity generation would not significantly increase, given the 7-9GW Power CCS would displace older and less efficient unabated gas power stations already operating and reduce importing unabated gas generation from abroad via the interconnectors. Importantly, Power CCS can provide a safety net to capture emissions from any gas required to keep the lights on in the event of delays to the roll out of renewables or nuclear.
The report is by LCP Delta, who are consultants based in Edinburgh.
The report says this about the transition to hydrogen.
Power CCS also presents significant opportunities to kickstart, then transition to, a hydrogen economy, benefitting from the synergies between CCS and hydrogen, including proximity to large-scale renewable generation and gas storage facilities which can support the production of both electrolytic and CCS-enabled hydrogen.
And this about the reduction in carbon emissions.
The existing renewables ambition and the accelerated Power CCS ambition are expected to save a total of 72 million tonnes of CO2 by 2040 compared to commitments in the UK’s Net Zero Strategy from October 2021.
I don’t think there’s much wrong with this analysis.
But of course the greens will trash it, as it was paid for by SSE.
I have a few thoughts.
Carbon Capture And Use
I believe we will see a great increase in carbon capture and use.
- Carbon dioxide is already an ingredient to make Quorn.
- Carbon dioxide is needed for fizzy drinks.
- Carbon dioxide can be fed to tomatoes, salad plants, herbs and flowers in giant greenhouses.
- Carbon dioxide can be used to make animal and pet food.
- Carbon dioxide can be used to make building products like plasterboard and blocks.
- Carbon dioxide can be added to concrete.
- Carbon dioxide can be used as a refrigerant and in air-conditioning. There are one or two old Victorian systems still working.
Other uses will be developed.
Carbon Capture Will Get More Efficient
Carbon capture from power stations and boilers, that use natural gas is a relatively new process and its capture will surely get better and more efficient in the next few years.
Gas From INTOG
I explain INTOG in What Is INTOG?.
One of INTOG’s aims, is to supply electricity to the oil and gas rigs and platforms in the sea around the UK.
Currently, these rigs and platforms, use some of the gas they produce, in gas turbines to create the electricity they need.
- I have seen reports that ten percent of the gas that comes out of the ground is used in this way.
- Using the gas as fuel creates more carbon dioxide.
Decarbonisation of our oil and gas rigs and platforms, will obviously be a good thing because of a reduction of the carbon dioxide emitted. but it will also mean that the gas that would have been used to power the platform can be brought ashore to power industry and domestic heating, or be exported to countries who need it.
Gas may not be carbon-neutral, but some gas is more carbon-neutral than others.
SSE’s Plans For New Thermal Power Stations
I have taken this from SSE’s news item.
SSE has deliberately chosen to remain invested in the transition of flexible thermal electricity generation due to the key role it plays in a renewables-led, net zero, electricity system and is committed to decarbonising the generation.
Together with Equinor, SSE Thermal is developing two power stations equipped with carbon capture technology. Keadby 3 Carbon Capture Power Station is based in the Humber, the UK’s most carbon-intensive industrial region, while Peterhead Carbon Capture Power Station is located in the North East of Scotland. Combined, the two stations could capture around three million tonnes of CO2 a year.
Studies have shown that Keadby and Peterhead Carbon Capture Power Stations could make a lifetime contribution of £1.2bn each to the UK economy, creating significant economic opportunity in their respective regions. Both will be vital in supporting the huge amount of renewables which will be coming on the system.
SSE Thermal and Equinor are also collaborating on Keadby Hydrogen Power Station, which could be one of the world’s first 100% hydrogen-fuelled power stations, and Aldbrough Hydrogen Storage, which could be one of the world’s largest hydrogen storage facilities.
Note.
- SSE appear to think that gas-fired power stations with carbon capture are an ideal backup to renewables.
- If gas is available and it can be used to generate electricity without emitting any carbon dioxide, then why not?
- Hydrogen is coming.
Things will get better.
Is A Virtuous Circle Developing?
Consider.
- Spare wind electricity is turned into hydrogen using an electrolyser or perhaps some world-changing electro-chemical process.
- The hydrogen is stored in Aldbrough Hydrogen Storage.
- When the wind isn’t blowing, hydrogen is used to backup the wind in Keadby Hydrogen power station.
- The other Keadby power stations can also kick in using natural gas. The carbon dioxide that they produce, would be captured for storage or use.
- Other users, who need to decarbonise, can be supplied with hydrogen from Aldbrough.
Note.
- Gas turbines are throttleable, so if National Grid wants 600 MW to balance the grid, they can supply it.
- As time progresses, some of the gas-fired power stations at Keadby could be converted to hydrogen.
- Rough gas storage is not far away and could either store natural gas or hydrogen.
- Hydrogen might be imported by tanker from places like Africa and Australia, depending on price.
Humberside will be levelling up and leading the decarbonisation of the UK.
If you have an energy-hungry business, you should seriously look at moving to Humberside.
Gasunie Investigates Hydrogen Network In North Sea

Ricardo Supports Toyota To Develop Its First UK-Based Hydrogen Light Commercial Vehicle
The title of this post, is the same as that of this press release from Ricardo.
This is the first paragraph.
Ricardo, a global strategic, environmental, and engineering consulting company, is supporting Toyota, in partnership with the APC, on a significant, multi-year project to develop its first zero emission hydrogen powered light commercial vehicle in the UK.
Note.
- Ricardo is a long-established engineering consultancy, headquartered in Shoreham, that employs 3,000 people and has a turnover of around £350,000. It has a high reputation, especially in the design of diesel engines.
- Ricardo has already converted a diesel bus to hydrogen, which I wrote about in Ricardo Repowers Double Decker Diesel Bus With Hydrogen Fuel Cells.
- The zero emission hydrogen powered light commercial vehicle, will be based on the Toyota Hilux, of which nearly twenty million have been built.
- Toyota already produce the hydrogen-powered Mirai.
- The APC is the UK Government’s Advanced Propulsion Centre.
This looks like one of those collaborations in the 1960s between Ford and Lotus, that produced the iconic Lotus Cortina.
The press release says this about Ricardo’s role in the project.
The Toyota Hilux hydrogen variant will be the first of its kind, manufactured and assembled at Toyota’s Derby-based facility and is scheduled for prototype production in 2023. Ricardo has been chosen as a partner by Toyota due to its proven experience in applying advanced propulsion technologies and expertise in hydrogen fuel cell integration, including for the UK’s first hydrogen transport hub.
Ricardo’s role in the project is to integrate the complete hydrogen fuel cell, fuel storage system, and controls including design, analysis, and validation. The integration ensures efficient operation of all systems to give an excellent vehicle range and supports attributes for longevity and reliability. Working as part of the consortium, Ricardo will support the delivery of a complete turnkey solution, which will create greater agility for Toyota in the UK supply base and a quicker turnaround in the design of low volume manufacturing.
This certainly looks like a co-operation between equals.
I have a few thoughts on the fuel cells.
The Wikipedia entry for the Toyota Mirai says this about the fuel cells for that car.
The first generation of Toyota FC Stack achieved a maximum output of 114 kW (153 hp). Electricity generation efficiency was enhanced through the use of 3D fine mesh flow channels. These channels—a world first, according to Toyota—were arranged in a fine three-dimensional lattice structure to enhance the dispersion of air (oxygen), thereby enabling uniform generation of electricity on cell surfaces. This, in turn, provided a compact size and a high level of performance, including the stack’s world-leading power output density of 3.1 kW/L (2.2 times higher than that of the previous Toyota FCHV-adv limited-lease model), or 2.0 kW/kg. Each stack comprises 370 (single-line stacking) cells, with a cell thickness of 1.34 mm and weight of 102 g. The compact Mirai FC stack generates about 160 times more power than the residential fuel cells on sale in Japan.[40] The Mirai has a new compact (13-liter), high-efficiency, high-capacity converter developed to boost voltage generated in the Toyota FC Stack to 650 volts.
As a rudimentary search of the Internet says that an entry-level HiLux has a 148 hp diesel engine, it seems that Toyota’s own fuel cells could be in the right ball park.
This second press release from Ricardo is entitled Hyzon And Ricardo To Deliver Hydrogen Fuel Cell Systems For Commercial Vehicles.
These are the first two paragraphs.
Ricardo is a world-class environmental, engineering and strategic consulting company, is partnering with leading hydrogen vehicle supplier Hyzon Motors Inc. on developing and deploying commercial systems to support the decarbonisation of the global transport and energy sectors.
The companies announced today they will be working to combine Hyzon’s high-power-density fuel cell stack with Ricardo’s unrivaled software and controls, thermal management and proven track record advising customers on hydrogen fuel cell technology.
Note, that the press release dates from December 2021.
The last paragraph of the press release is probably the most significant.
The potential of the Hyzon-Ricardo engagement has already borne fruit with the debut of the Ricardo Vehicle Integrated Controls and Simulation (VICS) control system within the Hyzon fuel cell electric truck at the Advanced Clean Transportation conference in September. Moving forward, Ricardo will support Hyzon in a global capacity on the development and deployment of advanced energy management and propulsion systems to accelerate the realisation of net zero initiatives across all modes of transport.
Note.
- Have Ricardo used Hyzon fuel cells to create their hydrogen-powered bus? I wrote about this project in Ricardo Repowers Double Decker Diesel Bus With Hydrogen Fuel Cells.
- If Ricardo and Hyzon have been working together for a few years, the timescale would fit.
- As a Graduate Control Engineer, I know that with complex engineering systems of all kinds, good control is often hard to achieve. Perhaps, Ricardo have cracked it!
I can certainly see, Ricardo playing a similar role in the creation of Toyota’s Hydrogen HiLux.
Conclusion
It looks to me, that with their hydrogen deals with Toyota and Hyzon, Ricardo are converting themselves from a giant in the field of diesel engine technology to a significant player in the field of hydrogen power.
