Cummins Launches Accelera By Cummins To Advance The Transition To A Zero-Emissions Future
The title of this post, is the same as that of this press release from Cummins.
These paragraphs outline the creation of the new brand.
Global power and technology leader Cummins Inc. (NYSE: CMI) today announced the launch of Accelera by Cummins, a new brand for its New Power business unit. Accelera provides a diverse portfolio of zero-emissions solutions for many of the world’s most vital industries empowering customers to accelerate their transition to a sustainable future.
The launch of Accelera is a significant step forward in Cummins’ efforts to achieve its Destination Zero strategy, focused on evolving Cummins technologies to reach zero emissions across its product portfolio. Cummins’ Destination Zero strategy is rooted in the understanding that multiple solutions are required to achieve industry-wide decarbonization across the diverse applications the company powers. Over the past several years, Cummins has invested more than $1.5 billion in research and technology, capital and acquisitions to build Accelera’s leadership and technological capabilities. Accelera is now a global leader in zero-emissions technologies, providing battery electric and fuel cell electric solutions across commercial and industrial applications with hundreds of electrolyzers generating hydrogen around the world today.
The press release then gives details of the zero-carbon products, that are in Accelera’s portfolio.
The press release finishes by announcing some zero-carbon projects. These are ones, thaat are new to me.
- Accelera by Cummins will supply a 90-megawatt proton exchange membrane electrolyzer system for Varennes Carbon Recycling’s plant in Quebec, Canada.
- Accelera and Blue Bird aim to power a new fleet of 1,000 electric school buses across the United States over the next 12-18 months.
- Cummins’ breakthrough technologies have reduced the company’s product emissions by more than 90% over the past 25 years, and Accelera will continue to advance the company’s path toward a zero-emissions future.
- Increasing global electrolyzer manufacturing capacity with gigawatt-scalable plants in Fridley, Minnesota – its first in the United States – and in Spain (now under construction).
- Powering the world’s first hydrogen refueling station for ships, cars, trucks and industrial customers in Antwerp, Belgium
- Powering the world’s first megawatt-scale demonstration plant for storing wind energy in the natural gas grid in Windgas Falkenhagen, Germany
- Deploying four hydrogen-fuel-cell-powered class 8 heavy-duty trucks with several marquis fleet customers in the United States.
- Powering refuse trucks with FAUN across Europe.
Cummins has arrived and will be a big player, as we more towards a zero-carbon world.
Only two people are mentioned in the press release.
- Jennifer Rumsey, Cummins President and Chief Executive Officer.
- Amy Davis, who has led the New Power business unit since 2020, will serve as President of Accelera.
Cummins has changed itself! Is it changing the world?
Wrightbus: Ballymena Company Gets Order For 117 Buses
The title of this post, is the same as that of this article on the BBC.
This is the sub-heading.
County Antrim firm Wrightbus has secured a £25.3m order to build 117 zero-emission buses for use in England
And this is the first paragraph.
Operated by First Bus, the vehicles will be used in Yorkshire, Norfolk, Portsmouth and Hampshire.
They don’t say, whether the buses are battery or hydrogen powered.
Should There Be Limits To The Type Of Vehicles Allowed In The Blackwall And Silvertown Tunnels?
When the Silvertown Tunnel opens in 2025, the tunnel and the nearby Blackwall Tunnel will be tolled.
But will there be any restrictions on the vehicles that can use the tunnels, other than those that apply to the Blackwall Tunnel at the present time, which are detailed in Wikipedia.
The tunnels are no longer open to pedestrians, cyclists or other non-motorised traffic, and the northbound tunnel has a 4.0-metre (13.1 ft) height limit.
Note.
- I suspect that pedestrians, cyclists or other non-motorised traffic will also be banned from the Silverton Tunnel.
- But the height limit will be relaxed for the Silverton Tunnel to allow large trucks and double-deck buses to use the tunnel.
According to this web page, which is entitled the Silvertown Tunnel Bus Network Proposals, the planned buses through the tunnel include.
- 108 – As now, with a minor route change.
- 129 – As now, but extended from North Greenwich station to Great Eastern Quay.
- X329 – An express bus from Grove Park station to Canary Wharf, which runs non-stop through the Silvertown Tunnel.
Note.
- The 108 goes through Blackwall and is a single decker bus.
- The 129 and the X329 will go through Silvertown and could be double decker buses.
- There appears to be no mention of any provision for cycles.
- I would assume wheelchairs, buggies and cases will be accommodated as they are on current London buses.
I also think, that the buses must be zero-carbon, which would mean battery-electric or hydrogen.
In Hydrogen-Powered Vehicles And Trains In Tunnels, I looked at the feasibility of running hydrogen buses through the tunnel and came to this conclusion.
I am confident, that we will achieve a safety regime, that allows hydrogen-powered vehicles and trains to be certified to pass through tunnels.
The great advantage of hydrogen buses on the three routes would be that they would probably only need to be filled up once a day, but electric buses might need constant charging.
Provision For Cycles
I think it is essential to have provision for cycles across the river.
- Folded cycles can be taken almost anywhere on London’s transport system.
- Non-folding cycles can be taken most places on London’s transport system, but the hours are restricted.
- There’s always the Woolwich Ferry.
- Given that the 108 bus seems to weave its way through the East End, I suspect that this bus couldn’t be longer to carry cycles.
I have seen double-deck buses, with provision for cycles at the back of the lower deck in Europe.
- Perhaps buses like these, could be used on the 129 and X329 routes.
- A search of the Internet found some buses in East Yorkshire with provision for two standard cycles.
- The 129 bus could ferry bikes between North Greenwich station and a convenient stop on the North side of the river.
- The X329 bus could ferry bikes over the non-stop section of the route between the Sun in the Sands and Leamouth roundabouts.
There could be shorter routes adding extra capacity between the stops, where bikes are loaded and unloaded.
Large Trucks Through The Tunnel
If buses become zero-carbon through the Blackwall and Silverton Tunnels, then why shouldn’t large trucks be zero-carbon?
I think this could be the carrot combined with free passage for zero-carbon vehicles that could clean up Central London’s polluted air.
Smaller Vehicles
Why not gradually reduce the size of vehicles going through the tunnels that must be zero-carbon?
Conclusion
The Silvertown and Blackwall Tunnels can be used as the drivers to clean up Central London’s air.
Equipmake Hybrid To Battery Powered LT11
The bus in this video from Public Transport UK, may look like any of the thousand New Routemasters on the streets of London.
But it’s not, as it’s been given a transmission transplant by Equipmake of Snetterton in Norfolk.
The observant amongst you will notice, it has a refurbished interior, as I wrote about in My First Ride In A Refurbished New Routemaster.
There is also this press release from Equipmake, which is entitled Equipmake Showcases Sector-Leading Repower Technology With Fully-Electric New Routemaster Bus.
Some points from the press release.
- Equipmake’s cutting-edge Zero Emission Drivetrain (ZED), uses a 95% British-built component content.
- With pre-service trials already started in London, operated by Metroline, the electric version of the New Routemaster will continue to be assessed over the next six months.
- The repowered New Routemaster, developed by Equipmake at its base in Snetterton, Norfolk, features a 400kWh battery enabling an expected in-service range of 150 miles – more than enough for a day’s running.
- The development of the all-electric New Routemaster has come about thanks to a programme part funded by the UK Advanced Propulsion Centre (APC).
- Over the coming months, Equipmake will be trialling additional repowered buses with other bus operators across the UK.
- Featuring an advanced water-glycol cooling circuit, the system has the added benefit of providing interior heating during cold conditions with captured thermal energy.
- When the battery is depleted at the end of a complete duty cycle, it can be recharged at the depot overnight via a CSS DC charging point.
But this is the bit I really like.
Under the skin, the New Routemaster also features Equipmake’s HTM 3500 electric motor. Seamlessly integrated into the prop shaft without the need for a separate transmission, the motor is precisely engineered to meet the demanding requirements of a fully-laden double-decker bus by producing 3,500Nm torque at a motor speed of just 1,000rpm and delivering 400kW maximum power.
It sounds a bit like a modern reincarnation of a TASC unit (torque and speed control unit), which was an industrial drive from the 1960s, used to precisely control industrial machines. I never used one, but I worked in a section at Enfield Rolling Mills, that did.
One car manufacturer of the time, was using them as an automatic transmission for a small car. It might have been Hillman.
A Comparison With The Wrightbus Streetdeck Electroliner BEV
The Wrightbus Streetdeck Electroliner BEV is the company’s latest electric double decker bus and a comparison can be made.
Seats
Equipmake LT11 – 87
Electroliner BEV – 96
Battery Size
Equipmake LT11 – 400 kWh
Electroliner BEV – 340 or 454 kWh
Range
Equipmake LT11 – 150 miles
Electroliner BEV – 200 miles with 454 kWh battery.
Conclusion
This New Routemaster, is certainly no ordinary electric bus.
With the batteries on hybrid buses needing to be replaced regularly, Eqipmake’s transmission transplant could also be scheduled, when a bus needs a new battery.
With Lotus just up the road, the engineering is certainly Normal for Norfolk!
Government Boosts Hydrogen Buses With £26m
The title of this post, is the same as that of this article on Energy Live ~News.
These are the first two paragraphs.
A Northern Irish bus company is receiving £26 million in funding to build electric and hydrogen buses.
Wrightbus built the world’s first hydrogen double-decker bus in 2020 and is now looking to export its zero-emission buses worldwide to Australia, Germany, Italy, France and Spain.
Other points from the article include.
- Wrightbus are aiming to build 3,000 zero-emission buses.
- Jobs could increase by 300.
- They would like to increase exports by 40 %.
It looks like there’s a future in zero-emission buses.
BP To Charge Up Vehicle Battery Research
The title of this post is the same as that of this article in The Times.
This is the title on a stock picture at the top of the page.
BP, whose profits benefited from soaring oil and gas prices, plans to invest heavily in research to develop solutions to help to decarbonise the transport sector.
I’m unsure about the picture, but it could be a number of buses or trucks connected to a large battery.
This press release on the BP web site, is the original source for The Times article and it is entitled BP To Invest Up To £50 million In New Global Battery Research And Development Centre In Britain.
The press release starts with these bullet points.
- bp continuing to invest in the UK, with new investment of up to £50 million for new electric vehicle battery testing centre and analytical laboratory in Pangbourne.
- Aims to advance development of engineering, battery technology and fluid technology and engineering into new applications such as electric vehicles, charging and data centres.
- New facilities at its Castrol headquarters and technology centre expected to open in 2024, supporting the technology, engineering and science jobs housed there today.
I find these sentences interesting.
new applications such as electric vehicles, charging and data centres
This sentence is a bit of a mess as electric vehicles are not new, charging is well established and what have data centres got to do with batteries.
I have a friend, who runs a large fleet of electric buses and charging is a problem, as getting the required number of MWhs to the garage can be a problem in a crowded city.
But could it be, that BP are thinking of a battery-based solution, that trickle-charges when electricity is affordable and then charges buses or other vehicles as required, throughout the day?
I believe that a battery based on process engineering like Highview Power’s CRYOBattery could be ideal in this situation.
- Effectively, the bus garage or transport parking would have its own high capacity battery-powered charging network.
- The storage capacity of the battery would be geared to the daily charge load of the vehicles.
- It would reduce the cost of electricity to the operator.
Such a battery might also be ideal to power a battery charging station.
I don’t know much about data centres, except that they need a lot of electricity.
Would driving data centres from a battery, that was trickle-charged overnight mean that the cost of electricity was reduced?
bp today unveiled plans to invest up to £50 million (around $60 million) in a new, state-of-the-art electric vehicle (EV) battery testing centre and analytical laboratory in the UK
There are a lot of battery ideas in the pipeline, so will one of the tasks be to find the best batteries for BP’s needs?
The site already undertakes research and development of fuels, lubricants and EV fluids and aims to become a leading hub for fluid technologies and engineering in the UK
You don’t think of lubricants being associated with electric vehicles, but obviously BP thinks it’s a serious enough topic to do some research.
The new facilities will help advance the development of leading fluid technologies and engineering for hybrid and fully battery electric vehicles, aiming to bring the industry closer to achieving the key tipping points for mainstream electric vehicle (EV) adoption.
This is self-explanatory.
Castrol ON advanced e-fluids manage temperatures within the battery which enables ultra-fast charging and improves efficiency, which help EVs to go further on a single charge and extend the life of the drivetrain system
Lubrication helps the world go round.
In addition, the advanced e-fluid technologies and engineering can be applied to other industries such as thermal management fluids for data centres where demand is rising exponentially
This is an interesting application and it will become increasingly important.
The growth of EV fluids is a huge opportunity, and we aim to be the market leader in this sector
I didn’t realise that EV fluids were so important.
The press release says this about the current status.
Two thirds of the world’s major car manufacturers use Castrol ON EV fluids as a part of their factory fill and we also supply Castrol ON EV fluids to the Jaguar TCS Racing Formula E team.
This press release on the Castrol web site is entitled CASTROL ON: Range Of Advanced E-Fluids For Mobility On Land, Sea And In Space.
This is the Castrol ON E-Fluids home page.
Where Will BP Need Batteries?
I can see the following applications are in BP’s sight from this press release.
- Charging fleets of buses and trucks at their garage.
- Powering battery-charging stations at filling stations.
- Providing uninterruptable electricity feeds.
- Powering data centres.
I will give a simple example.
Suppose a bus company wants to electrify the buses in a town.
- They will have thirty double-deck buses each with a 500 kWh battery.
- Wrightbus electric buses charge at 150 kW.
- Charging all buses at the same time would need 4.5 MW
- Each bus will need to be charged overnight and once during the day.
- This means the bus company will need 30 MWh of power per day.
- The largest wind turbines today are around 12 MW and have a capacity factor of 30 %.
- A single turbine could be expected to generate 86 MWh per day.
It looks to me, that a battery in the garage which could provide an output of 5 MW and had a capacity of 100 MWh would link everything together and support the following.
- A fleet of thirty buses.
- All buses charged overnight and at one other time.
- A 12 MW wind turbine.
- Power for the offices and other facilities.
- The battery would provide backup, when there is no wind.
- There would also be a mains connection to the battery for use, when the wind turbine failed.
The size of the battery and the turbine would depend on the number of vehicles and how often, they were to be charged.
BP could replace diesel sales to the bus or transport company, with leasing of a zero-carbon charging system.
Simple systems based on one or two wind turbines, solar panels and a battery would have several applications.
- Charging fleets of buses and trucks at their garage.
- Powering battery-charging stations at filling stations.
- Providing uninterruptable electricity feeds.
- Powering data centres
- Powering farms
- Powering new housing estates
- Powering factories
I can see this becoming a big market, that big energy companies will target.
Are BP planning to develop systems like this, as many of those, who might buy a system, are already their customers?
Choosing the best batteries and designing the system architecture would appear to be within the remit of the new Research Centre at Pangbourne.
Supporting Wind Farms
BP could certainly use a 2.5 GW/30 GWh battery at each of the three large wind farms; Mona, Morgan and Morven, that they are developing in the Irish Sea and off Aberdeen. These wind farms total 5.9 GW and a battery at each one, perhaps co-located with the offshore sub-station could mean that 5.9 GW was much more continuous.
The wind farms would be like virtual nuclear power stations, without any nuclear fuel or waste.
It would also mean that if the wind farm wasn’t needed and was told to switch off, the electricity generated could be stored in BP’s battery.
How many of BP’s other developments around the world could be improved with a co-located battery?
Process Technology
I am very keen on Highview Power’s CRYOBattery, but I do think that some parts of the design could benifit from the sort of technology that BP has used offshore and in the oil industry.
So will BP’s new battery research include offering advice to promising start-ups?
Rolls-Royce To Develop mtu Hydrogen Electrolyser And Invest In Hoeller Electrolyser
The title of this post, is the same as that of this press release from Rolls-Royce.
These are the three main points in the press release.
- Holdings in start-up companies in northern Germany secure Rolls-Royce Power Systems access to key green hydrogen production technology.
- Electrolysis systems for several megawatts of power.
- First demonstrator in 2023 using a Hoeller stack.
This is the introductory paragraph to the deal.
Rolls-Royce is entering the hydrogen production market and acquiring a 54% majority stake in electrolysis stack specialist Hoeller Electrolyzer, whose innovative technology will form the basis of a new range of mtu electrolyzer products from its Power Systems division. Hoeller Electrolyzer, based in Wismar, Germany, is an early-stage technology company that is developing highly efficient polymer electrolyte membrane (PEM) stacks, under the brand name Prometheus, for the cost-effective production of hydrogen.
This page on the Hoeller Electrolysis web site gives details of Prometheus.
- Hoeller are planning small, medium and large electrolyser modules, the largest of which is rated at 1.4 MW.
- Load changes of between 0 and 100 % within seconds.
- Cold start capability.
- It will produce 635 Kg/day.
- They are talking of a cost of 4€/Kg.
It all sounds good to me.
This paragraph is from the press release.
Founded in 2016, Hoeller Electrolyzer has positioned itself, with Prometheus, as one of the few highly specialized expert players in the field of high-efficiency PEM electrolysis stacks. Its founder, Stefan Höller, has more than a quarter of a century’s experience of developing electrolysis technology and has already registered 14 patents connected with Prometheus. Particularly high efficiency is promised by special surface technologies for the bipolar plates which significantly reduce the use of expensive precious metals platinum and iridium as catalysts, as well as increased output pressure.
I know a small amount about electrolysis and feel that Rolls-Royce may have got themselves a high-class deal.
Rolls-Royce’s large German presence in companies like mtu, will also help to smooth any doubts about the deal.
This paragraph indicates a shared belief.
Rolls-Royce and Hoeller Electrolyzer are united by a shared belief in the opportunity of zero-carbon energy – both for power supply and the propulsion of heavy vehicles. With decades of experience and systems expertise, Rolls-Royce is going to develop a complete electrolyzer system and has a global sales and service network, which opens up the potential for significant worldwide sales.
But perhaps, this is the most significant paragraph of the press release.
Armin Fürderer, who heads up the Net Zero Solutions business unit of Power Systems, said: “We’re going to launch electrolyzers with several megawatts of power right from the start. A total output of over 100 megawatts is conceivable by combining several electrolyzers.”
A quick search of the Internet, indicates that 100 MW is the size of the world’s largest electrolysers.
Applications
I can see applications for these large electrolysers.
Rolls-Royce Power Systems
This is a sentence from the press release.
Hoeller Electrolyzer, whose innovative technology will form the basis of a new range of mtu electrolyzer products from its Power Systems division.
The Rolls-Royce Power Systems web site, has this mission statement.
The Power Systems Business Unit of Rolls-Royce is focused on creating sustainable, climate neutral solutions for drive, propulsion and power generation.
In Rolls-Royce Makes Duisburg Container Terminal Climate Neutral With MTU Hydrogen Technology, I describe one of Rolls-Royce Power Systems projects.
The title of this post, is the same as this press release from Rolls-Royce.
This is the first sentence.
Rolls-Royce will ensure a climate-neutral energy supply at the container terminal currently under construction at the Port of Duisburg, Germany.
There is also this Rolls-Royce graphic, which shows the energy sources.
It would appear batteries, combined heap and power (CHP), grid electricity, hydrogen electrolyser, hydrogen storage and renewable electricity are being brought together to create a climate-neutral energy system.
Note.
- The system uses a large hydrogen electrolyser.
- I suspect the hydrogen will be generated by off-peak electricity and local renewables.
- Hydrogen will probably power the container handling machines, ships, trucks, vehicles and other equipment in the port.
Hydrogen appears to be used as a means of storing energy and also for providing motive power.
I would suspect, the ultimate aim is that the port will not emit any carbon dioxide.
Other ports like Felixstowe and Holyhead seem to be going the hydrogen route.
Refuelling Hydrogen Buses and Charging Electric Buses
If you look at the Duisburg system, I can imagine a similar smaller system being used to refuel hydrogen buses and charge electric ones.
- The hydrogen electrolyser would be sized to create enough hydrogen for a day or so’s work.
- Hydrogen would be generated by off-peak electricity and local renewables.
- If an operator bought more buses, I’m certain that the architecture of the electrolyser would allow expansion.
- Hydrogen fuel cells would boost the electricity supply, when lots of buses needed to be charged.
- Any spare hydrogen could be sold to those who have hydrogen-powered vehicles.
- Any spare electricity could be sold back to the grid.
It should be noted that manufacturers like Wrightbus have developed a range of hydrogen and electric buses that use the same components. So will we see more mixed fleets of buses, where the best bus is assigned to each route?
I have used buses as an example, but the concept would apply to fleets of cars, trucks and vans.
Green Hydrogen
Large efficient electrolysers will surely be the key to producing large quantities of green hydrogen in the future.
It appears that about 55 MWh is needed to produce a tonne of green hydrogen using existing electrolysers.
The Hoeller electrolyser appears to be about 53 MWh, so it is more efficient.
Green Hydrogen From An Onshore Wind Farm
If you look at the average size of an onshore wind farm in the UK, a quick estimate gives a figure of 62 MW. I shouldn’t expect the figure for much of the world is very different, where you ignore the gigafarms, as these will distort the numbers.
An appropriately-sized electrolyser could be added to onshore wind farms to provide a local source of hydrogen for transport, an industrial process or a domestic gas supply for a new housing estate.
A single 5 MW wind turbine with a capacity factor of around 30 % would produce around 680 Kg of green hydrogen per day.
Green Hydrogen From An Offshore Wind Farm
There are basic methods to do this.
Put the electrolyser onshore or put the electrolyser offshore and pipe the hydrogen to the shore.
I think we will see some innovative configurations.
In ScotWind N3 Offshore Wind Farm, I described how Magnora ASA are developing the ScotWind N3 wind farm.
The floating turbines surround a concrete floater, which in the future could contain an electrolyser and tankage for hydrogen.
The ScotWind N3 wind farm is designed to be a wind farm rated at 500 MW.
I can see an electrolyser on the floater, of an optimal size to make sure all electricity is used.
Pink Hydrogen
Pink hydrogen, is zero-carbon hydrogen produced using nuclear-generated electricity.
There are industrial processes, like the making of zero-carbon chemicals, concrete and steel, that will require large quantities of zero-carbon green or pink hydrogen.
Rolls-Royce are developing the Rolls-Royce SMR, which will be a 470 MW small modular nuclear reactor.
One of these placed near to a steel works and coupled to one or more 100 MW electrolysers could provide enough zero-carbon electricity and hydrogen to produce large quantities of zero-carbon green steel.
Manufacturing
Rolls-Royce and their subsidiaries like mtu, seem to be extensive users of advanced manufacturing techniques and I would expect that they can improve Hoeller’s manufacturing.
Research And Development
The press release says this about the founder of Hoeller.
Its founder, Stefan Höller, has more than a quarter of a century’s experience of developing electrolysis technology and has already registered 14 patents connected with Prometheus.
If Rolls-Royce can develop and support Stefan Höller and his team, development could easily go to a higher level.
Conclusion
I think that Rolls-Royce have taken over a company, that will in the end, will design excellent efficient electrolysers.
A Planned Trip To Belfast
I’m thinking about going over to Belfast for a couple of days to have a look at the transport systems in the city and the wider Northern Ireland.
I have several things, I would like to do.
- Ride in the latest Wrightbus hydrogen and battery-electric buses.
- Ride in a Glider. I also intend to go to Pau to ride in a hydrogen-powered version of these Van Hool Equicity articulated buses, but Belfast is nearer.
- Perhaps, if I have enough time, I’ll visit a few touristy bits.
- Do a bit of research into offshore wind farms in Northern Ireland.
Has anybody got any advice?
UK On Track To Reach 4,000 Zero Emission Bus Pledge With £200 Million Boost
The title of this post, is the same as that of this press release from the Government.
These are the main points of the press release.
- Nearly 1,000 more zero-emission buses to be funded in towns and cities across the country, bringing the total funded in England to 2000 so far under this government.
- A further 600 zero-emission buses have been funded in Scotland, Wales and Northern Ireland.
- Comes as consultation launched on ending sale of all new non-zero emission buses from 2025 to 2032.
- Government continues taking unprecedented action to hit net zero and level up transport across the country.
Areas to get the new buses include.
- Blackpool
- Greater Manchester
- Hertfordshire
- Norfolk
- North Yorkshire
- Nottingham
- Oxfordshire
- Portsmouth
- South Yorkshire
- West Midlands
- West Yorkshire
- York
I would also like to see the government fund trials for the conversion of suitable buses to zero carbon. I certainly believe that London’s New Routemaster buses could be converted to hydrogen.
The Anonymous Widower
