UK’s First 100mph Battery-Diesel Hybrid Train Enters Passenger Service
The title of this post, is the same as that of this article on ITV.
These are the first three paragraphs.
The UK’s first 100mph battery-diesel hybrid train is entering passenger service to cut carbon emissions and boost air quality.
It was developed by adding a powerful battery to a 20-year-old diesel train to reduce fuel consumption and CO2 emissions by 25%, according to owner Porterbrook.
The firm added that the two-carriage train, named HybridFLEX, also provides a 75% decrease in noise and a 70% decrease in nitrogen oxide.
The battery-diesel hybrid transmission is from MTU, who are a Rolls-Royce company and they go further with this press release which is entitled World Premiere: MTU Hybrid PowerPack From Rolls-Royce Enters Passenger Service.
This is the first paragraph.
Rolls-Royce, Porterbrook and Chiltern Railways are making rail history together with a climate-friendly world premiere: A hybrid diesel-battery-electric train that reduces CO2 emissions by up to 25% entered passenger service in the UK today for the first time. The so-called HybridFLEX train is powered by two mtu Hybrid PowerPacks and is operated by Chiltern Railways on the route between London Marylebone and Aylesbury. Together with the leasing company Porterbrook and Chiltern Railways, Rolls-Royce has converted a Class 168 DMU into the HybridFLEX train. The partners are proving that existing rail vehicles can be used in a climate-friendly way without the need to install complex and expensive new infrastructure. It is the world’s first regular passenger operation with mtu Hybrid PowerPacks, of which 13 have already been ordered.
This is significant for the railways of the UK.
The train that has been converted is a Class 168 train, which itself had been converted from a Class 170 train, when it transferred to Chiltern Railways in 2016.
I think this means that all Bombardier Turbostars in Classes 168, 170, 171 and 172 can probably be fitted with MTU Hybrid PowerPacks.
That is the following numbers of trains and cars.
- Class 168 – 28 trains – 86 cars
- Class 170 – 139 trains – 372 cars
- Class 171 – 20 trains – 56 cars
- Class 172 – 39 trains – 93 cars
Note.
- This totals to 226 trains and 607 cars.
- As each car has an engine, this will be an order of 607 PowerPacks, if all trains were to be converted.
This could certainly help to meet the Government’s aim of getting rid of all diesel only trains by 2040.
Can The CAF Civities Be Converted?
There are three Classes of CAF Civity diesel multiple units; 195, 196 and 197, all of which have Rolls-Royce MTU engines.
Could these be converted to hybrid operation by the swapping of the current diesel engines for MTU Hybrid PowerPacks?
I would suspect they could, as the CAF Civity trains might have been designed after MTU disclosed plans of the MTU Hybrid PowerPack to train builders prior to its announcement in September 2018.
Conclusion
MTU Hybrid PowerPacks could go a long way to eliminating diesel-only trains on UK railways. They could even run the diesels on Hydrotreated Vegetable Oil (HVO) to lower their carbon-footprint further.
BP Snaps Up 30 Per Cent Stake In Green Biofuels Ltd
The title of this post, is the same as that of this article on Business Green.
So why would BP take a stake in Green Biofuels?
This paragraph in the Wikipedia entry for BP, outlines the company’s future philosophy.
From 1988 to 2015, BP was responsible for 1.53% of global industrial greenhouse gas emissions. BP has set a goal to cut its greenhouse gas emissions to net-zero by 2050. BP plans to increase its investments in renewables 10 times and reduce oil production by 40% from current levels by 2030.
BP is doing things like developing wind and solar farms to achieve these aims.
BP also seems to be investing in both blue and green hydrogen.
But possibly, the two hardest products to decarbonise are diesel for heavy transport and aviation fuel.
Looking at Green Biofuels web site, the Wikipedia entry for Hydrotreated Vegetable Oil (HVO) and other sources, Green Biofuels product; GD+ seems to make a good fist of reducing carbon emissions and pollution, if it replaces diesel.
DB Cargo UK and HVO
DB Cargo UK have a fleet of nearly two hundred large diesel locomotives in the UK.
DB Cargo UK have been experimenting with HVO, as I wrote about in Powered By HVO.
The company has issued a press release on these trials of HVO, from which this is an extract.
DB Cargo UK’s Head of Asset Management and Maintenance Steve Wilkinson said the company was collaborating with one of the UK’s leading suppliers of HVO fuel which already worked with high-profile brands like Caterpillar, John Deere, Volvo and Mercedes-Benz.
“We are very pleased with the initial performance of the HVO fuel which we could use instead of or alongside traditional red diesel. The fact it is compatible with our existing diesel means investment in new storage and fuelling facilities would also be kept to a minimum,” he added.
“On top of that, it performs well at low temperatures, has a longer lifespan and is biodegradable,” he added.
DB Cargo UK currently operates 228 diesel and electric locomotives that transport in the region of 37 million tonnes of freight each year across the UK and into Europe.
It uses approximately 45 million litres of red diesel a year.
Was one of the UK’s leading suppliers of HVO fuel, a company called Green Biofuels?
Note that DB Cargo UK’s spokesman makes these points about the fuel.
- They are very pleased with initial performance.
- It is a straight swap for red diesel and it appears locomotives can run on either. He doesn’t say it but can it run on one fuel contaminated with the other? I suspect it’s a possibility.
- Current storage can be used for HVO.
- I get the impression that swapping from red diesel to HVO wouldn’t be the most challenging of operations.
- It performs well at low temperatures. One train-driver told me, that one of the worse parts of the job, is picking up a train from a depot high in the Pennines on a cold day in the winter. That must apply to locomotives.
- It has a longer lifespan.
- It is biodegradable. I haven’t walked through an engine shed, since I used to bunk them as a child to get engine numbers, but they were filthy places, with oil and diesel all over the floor.
That sounds to me, like DB Cargo UK have decided that HVO is an excellent fuel and for them to swap to HVO, would be no more difficult than to swap between red diesel from BP to red diesel from Shell.
This is an extract from the Business Green article.
Founded in 2013, Green Biofuels is the UK’s largest provider of HVO, having delivered over 55 million litres of HVO products to the UK market over the past two years.
If DB Cargo UK wanted to swap from red diesel to HVO, they would need nearly all of Green Biofuels current production.
So have Green Biofuels run to BP and said can you help us out?
Red Diesel Replacement
This document on the Government web site is entitled Reform Of Red Diesel And Other Rebated Fuels Entitlement.
There is a section, which is entitled Policy Objective, where this is said.
In June 2019, the UK became the first major economy in the world to pass laws guaranteeing an end to its contribution to global warming by 2050. The target will require the UK to bring all greenhouse gas emissions to net zero by 2050, compared with the previous target of at least an 80% reduction from 1990 levels. The government also launched in 2019 an ambitious new strategy to clean up the air and save lives, given air pollution is one of the biggest continuing threats to public health in the UK.
Red diesel is diesel used mainly for off-road purposes, such as to power bulldozers and cranes used in the construction industry, or to power drills for oil extraction. It accounts for around 15% of all the diesel used in the UK and is responsible for the production of nearly 14 million tonnes of carbon dioxide a year. Red diesel used in the construction and infrastructure building sectors was also estimated to have caused 7% of nitrogen oxide emissions and 8% of PM10 emissions (a type of particulate matter) in London in 2018.
At Budget 2020, the government therefore announced that it would remove the entitlement to use red diesel and rebated biodiesel from most sectors from April 2022 to help meet its climate change and air quality targets. The tax changes will ensure that most users of red diesel use fuel taxed at the standard rate for diesel from April 2022, like motorists, which more fairly reflects the harmful impact of the emissions they produce. Removing most red diesel entitlements will also help to ensure that the tax system incentivises users of polluting fuels like diesel to improve the energy efficiency of their vehicles and machinery, invest in cleaner alternatives, or just use less fuel.
It doesn’t say, but I have found references to the fact that HVO pays the same tax rate as diesel, despite the evidence, that it appears to be more environmentally friendly.
If I was the Chancellor, I would certainly adjust the tax system, so that red diesel users who changed to HVO and other fuels, paid tax in proportion to the emissions and pollution they caused.
So have BP decided that Green Biofuels is the best interim solution to reduce emissions from diesel fuel and taking a stake, is the best way to get the required access to the product?
Could BP be thinking about replacing red diesel with a better green diesel?
- Red diesel and GD+ could be acceptable to all diesel vehicles and equipment. So farmers for rxample, could run tractors and combines on the same fuel as their truck or Range Rover.
- Businesses, like farmers, who often have tanks for both red diesel and normal diesel, would only need one tank.
- Businesses with a green profile, would surely like it for their vehicles.
- Organic farmers would like it for their tractors.
- The availability of a green diesel would enable red diesel users to change to hydrogen or battery operation, at the optimal time.
I can see Prince Charles handing out green stars all round.
What Will Happen To Northern’s Class 195 Trains?
Northern’s Class 195 trains could be a problem in the future.
- They are diesel multiple units.
- There are twenty-five two-car trains and thirty-three three-car trains.
- All cars have a Rolls-Royce MTU 6H1800R85L diesel engine, that drives the train through a ZF EcoLife 6-speed transmission.
- They are 100 mph trains, which is adequate for the routes they serve.
- According to Wikipedia, the trains are designed for a lifespan of thirty-five years, which takes the trains past the date, when it is intended that all trains should be zero-carbon.
It looks to me, that a plan will be needed to decarbonise these trains, as they are probably too new and costly to scrap.
These are possibilities to upgrade them to zero-carbon.
Rebuild as Class 331 Electric Trains
The design of the Class 195 trains is based on the same platform as that of the Class 331 trains.
I would expect that it could be possible to rebuild the Class 195 trains as Class 331 trains.
But it would be an expensive and disruptive process and would require a lot of electrification.
Some battery-electric versions could be created to cut the need for electrification.
Run The Trains On Net-Zero Hydrogenated Vegetable Oil Or Other Fuels
In Powered By HVO, I wrote about research going on into the use of Hydrogenated Vegetable Oil or HVO.
There is also ongoing research into other net-zero fuels that can be used in a diesel engine.
The process used by Velocys to create sustainable aviation fuel can also be used to produce diesel from various sources like disposable nappies, household waste and scrap wood.
Run The Trains On A Dual Fuel Basis With Hydrogen
In Grand Central DMU To Be Used For Dual-Fuel Trial, I talk about how Grand Central in collaboration with a company called G-volution are running experiments with dual-fuelling a Class 180 train. G-volution state that they could dual fuel with hydrogen using their technology.
The Class 180 trains have Cummins engines, but I suspect G-volution’s technology or something similar could be applied to the Rolls-Royce MTU engines in the Class 195 trains.
This could be a very promising route.
Convert The Diesel Engines To Run On Hydrogen
Cummins and JCB have developed internal combustion engines, that can run on hydrogen. I would be very surprised if Rolls-Royce MTU are not developing this technology.
Conclusion
There are options to convert the Class 195 trains into low or zero-carbon trains.

Freightliner Continue Trials On New Low Carbon Fuel
The title of this post, is the same as that of this article on Rail Technology Magazine.
This is the first paragraph.
As part of their commitment to carbon reduction Freightliner will conduct operational trials of a new low carbon fuel supplied by Green Biofuels Ltd (GBF).
And this paragraph described the fuel.
GBF are the UK’s leading provider of Hydrogenated Vegetable Oil (HVO) and the new fuel consists of 55% Shell GTL (gas to liquids) Fuel and 45% Gd+ HVO.
It does appear that hydrotreated vegetable oil or HVO, could be becoming an intermediate step on the route to decarbonisation, as I’ve posted about the fuel before in Powered By HVO.
The other promising route to decarbonisation must surely be that of producing fuel from waste, as pioneered by Velocys and others.
But they are only intermediate steps before hydrogen becomes the preferred zero-carbon fuel for rail freight services.
Railfreight Goes Back To Diesel As Electricity Costs Soar
The title of this post, is the same as that of this article on Railnews.
This is the first paragraph.
Some rail freight operators have abandoned electric traction, at least for now, because the price of electricity has been rising sharply. The electricity tariffs include a 40 per cent renewable energy tax, and following the latest rises diesel traction is now cheaper. The drivers’ union ASLEF is calling for the government to intervene, but Freightliner has already taken action.
This quote from the article is from ASLEF General Secretary; Mick Whelan.
Moving freight by rail rather than road is, inherently, a carbon-efficient mode of transport and an environmentally-friendly way of doing business. Electric-hauled freight services reduce emissions by 99 per cent; even moving goods by diesel traction reduces emissions by 76 per cent.
It looks to me, that a reputable and trusted environmental economist could come up with a compromise price and possibly a solution to improve the situation.
Possible solutions could include.
- Use of Biodiesel or Hydrotreated Vegetable Oil
- More energy storage.
Surely, though, the long term solution is hydrogen-powered locomotives. or dual-fuel locomotives, as I wrote about in Freightliner Secures Government Funding For Dual-Fuel Project.
Results For HS2’s Trial For Alternative Fuels Set To Cut Carbon Released
The title of this post, is the same as that of this article on Rail Technology Magazine.
This paragraph sums up the results.
Although the results demonstrated partial air quality benefits, when compared to red diesel, the trial showed possible carbon reduction opportunities via the sustainable sourcing of alternative fuels.
It looks like, there will be benefits from swapping from red diesel.
Iron Ore Miner Orders Heavy-Haul Battery Locomotive
The title of this post, is the same as that of this article on Railway Gazette.
This is the first two paragraphs.
Mining company Roy Hill has ordered a Wabtec FLXdrive battery-electric heavy-haul freight locomotive. This will replace one the four ES44ACi diesel-electric locos used to haul its 2 700 m long iron ore trains, and is expected to reduce fuel costs and emissions by ‘double digit’ percentages while also cutting maintenance costs.
The locomotive is scheduled to be delivered in 2023. It will have a capacity of 7 MWh, an upgrade from the 2·4 MWh prototype which Wabtec and BNSF tested in revenue service in California earlier this year.
Note.
- It will have a 7 MWh battery.
- 2700 metres is 1.6 miles.
It looks to me, that the three diesel locomotives and one battery locomotive are arranged as a massive hybrid locomotive and I suspect that with sophisticated control systems, those double digit cuts in fuel costs and emissions would be possible.
A couple of years ago, I took this picture near Shenfield.
This double-headed train has a Class 90 electric locomotive and a Class 66 diesel locomotive at the front of a long freight train.
- The Class 90 locomotive has an TDM system for multiple working.
- The Class 66 locomotive has an AAR system for multiple working.
So does this mean that the two locomotives can’t work together, which if it does begs the question of what is happening.
- Had the Class 66 locomotive failed and Class 90 was acting as a Thunderbird?
- Was the Class 66 locomotive being moved from one depot to another for maintenance or repair?
- Was it an experiment to see if the two locomotives could work together?
I sometimes think that I didn’t see this unusual formation, but then the camera doesn’t lie.
But could we learn from what Wabtec are doing for Roy Hill in Australia?
The Class 93 Locomotive
Rail Operations Group have already ordered thirty Class 93 tri-mode locomotives from Stadler, which have following power ratings.
- Electric – 4000 kW
- Diesel – 900 kW
- Hybrid – 1300 kW
If this locomotive is capable of hauling the heaviest intermodal freight trains out of Felixstowe, Southampton and other ports and freight terminals, it could contribute to substantial reductions in the diesel fuel used and emissions.
As an example, I will use a freight train between Felixstowe North Terminal and Trafford Park Euro Terminal.
- It is a route of 280 miles.
- I will ignore that it goes along the North London Line through North London and along the Castlefield Corridor through Manchester Piccadilly station.
- There is fifteen miles without electrification at the Felixstowe end.
- There is under three miles without electrification at the Manchester end.
On this service , it could be as much as 94 % of diesel and emissions are saved, if the Class 93 locomotive can haul a heavy freight train out of Felixstowe. A few miles of strategically-placed electrification at the Ipswich end would help, if required.
It must also be born in mind, that the Class 93 locomotive is a 110 mph locomotive on electric power and could probably do the following.
- Run at 100 mph on the busy Great Eastern Main Line.
- Run at faster speeds on the West Coast Main Line.
- Fit in well with the 100 mph passenger trains, that run on both routes.
So not only does it save diesel and carbon emissions, but it will save time and make the freight train easier to timetable on a route with lots of 100 mph passenger trains.
The Class 93 locomotive looks like it could be a game-changer for long-distance intermodal freight, especially, if there were short sections of strategically-placed electrification, added to the electrified network.
Emissions could also be reduced further by using some for of sustainable fuel.
The picture shows a Class 66 locomotive, which is powered by Hydrotreated Vegetable Oil or HVO.
I can see that all diesel-powered trains and locomotives will be powered by sustainable fuels by the end of this decade.
A Wabtec Battery-Electric Locomotive
Wabtec is building a battery-electric locomotive for Roy Hill in Australia.
This article on Railway Age talks about Wabtec’s FLXdrive battery locomotives and describes some features of the locomotive for Roy Hill in Australia.
It mentions pantographs and overhead wires to charge the batteries.
- Wabtec’s prototype battery locomotive has a power output of 3.24 MW and a battery size of 2.4 MWh
- The Roy Hill battery locomotive has a power output of 3.24 MW and a battery size of 7 MWh
I could envisage Wabtec designing a UK-sized battery-electric locomotive with these characteristics.
- 2.5 MW power output, which is similar to a Class 66 locomotive.
- A battery size of perhaps 1.8 MWh based on Wabtec’s FLXdrive technology.
- A pantograph to charge the batteries and also power the locomotive where electrification exists.
- 75 mph operating speed.
- Ability to work in tandem with a Class 66 locomotive.
All technology is under Wabtec’s control.
This locomotive could have a range of at least fifty miles on battery power.
I think this locomotive could handle these routes.
- Peterborough and Doncaster via the Great Northern and Great Eastern Joint Line via Lincoln, with some form of charging at halfway.
- Felixstowe and Nuneaton, with some extra electrification at some point between Peterborough and Leicester.
- Oxford and Birmingham, with possibly some extra electrification in the middle.
One option for charging electrification, would surely be to electrify passing loops.
I think a battery-electric locomtive based on Wabtec’s FLXdrive technology could be a very useful locomotive.
Could Wabtec’s Battery-Electric Locomotive Pair-Up With A Class 66 Locomotive?
Roy Hill will use their locomotive to form a consist of three diesel locomotives and one battery locomotive to obtain double-digit savings of fuel and emissions, when hauling iron-ore trains that are 1.6 miles long on a route of 214 miles.
We don’t have massive iron-ore trains like this, but we do move huge quantities of segregates and stone around the country in trains generally hauled by Class 66 locomotives.
So could a Class 66 or another suitable locomotive be paired-up with a battery-electric locomotive to make savings of fuel and emissions?
I would suggest that if it works in Australia, the technology will probably work in the UK.
The biggest problem for Wabtec is that the heavy end of the market may well be a good one for hydrogen-powered locomotives. But Wabtec are going down that route too!
Conclusion
I am convinced that the two decarbonisation routes I have outlined here are viable for the UK.
But I also feel that locomotive manufacturers will produce hydrogen-powered locomotives.
Other companies like Alstom, Siemens and Talgo will also offer innovative solutions.
Powered By HVO
I took these pictures yesterday at Peterborough.
Note the locomotive is named Benjamin Gimbert GC.
DB Cargo have issued a press release on these trials of HVO.
Wikipedia also give more details of HVO.
The Anonymous Widower
