Rolls-Royce Releases mtu Rail Engines For Sustainable Fuels

The title of this post, is the same as that of this press release from Rolls-Royce.

The press release starts with these bullet points.

  • mtu Series 1300, 1500 and 1800 engines already released; Series 1600 and 4000 to follow shortly
  • Up to 90% CO2 savings by operating existing engines with Hydrotreated Vegetable Oil (HVO/renewable diesel)
  • Locally emission-free operation possible in combination with mtu Hybrid PowerPack
  • Field tests with DB Cargo and RDC Autozug Sylt

Note.

  1. Hitachi Class 800, 802, 805 and Class 810 trains appear to use Series 1600 engines.
  2. CAF Class 195, 196 and Class 197 trains appear to use Series 1800 engines.
  3. Class 43 power cars, as used in InterCity 125 trains appear to use Series 4000 engines.

It would appear that many of the UK’s new diesel trains and the remaining Class 43 power-cars can be converted to run on HVO.

This paragraph from the press release gives more details.

Rolls-Royce is taking a significant step towards even more climate-friendly rail transport with the release of mtu rail engines for use with sustainable fuels. With synthetic diesel fuels of the EN15940 standard, CO2 emissions can be reduced by up to 100 percent compared to fossil diesel. Hydrotreated Vegetable Oil (HVO or renewable diesel), which is already commercially available today, reduces CO2 emissions by up to 90 percent. If the fuels are produced with the help of renewable energy and green hydrogen – through what is termed a Power-to-X process – existing rail vehicles can be operated in a completely CO2-neutral manner. The mtu Series 1800 engines which are used in mtu PowerPacks, as well as Series 1300 and 1500 for locomotives and multi-purpose vehicles, are already approved for use with synthetic fuels such as HVO. Series 1600 and versions of Series 4000 engines will follow in the near future. The release of engines for climate-friendly fuels requires a series of tests and trials and Rolls-Royce has found strong partners for this activity. DB Cargo and RDC Autozug Sylt have already tested or are currently testing mtu Series 4000 engines with HVO in their locomotives.

Rolls-Royce mtu seem to have covered all issues.

This is a very significant statement in the paragraph.

If the fuels are produced with the help of renewable energy and green hydrogen – through what is termed a Power-to-X process – existing rail vehicles can be operated in a completely CO2-neutral manner.

This must be the most affordable way to make your diesel trains zero carbon.

Conclusion

Rolls-Royce and Cummins seem to be doing a thoroughly professional job in decarbonising the diesel engines they have made in recent years.

It now needs someone to take small diesel engines down the conversion route, just as Rolls-Royce mtu and Cummins are cleaning up their large engines.

How Many Diesel Multiple Units In The UK Have Voith Hydraulic Transmissions?

This may seem to be a funny question to ask, but all will come clear later in the week.

Doing a quick search through Wikipedia finds the following trains.

  • Class 150 – 135 – two-car – 2 x 213 kW
  • Class 150 – 2 – three-car – 3 x 213 kW
  • Class 153 – 56 – one-car – 1 x 213 kW
  • Class 155 – 7 – two-car – 2 x 213 kW
  • Class 156 – 114 – two-car – 2 x 213 kW
  • Class 158 – 149 – two-car – 2 x 260-300 kW
  • Class 158 – 23 – three-car – 3 x 260-300 kW
  • Class 159 – 30 – three-car – 3 x 260-300 kW
  • Class 165 – 48 – two-car – 2 x 261 kW
  • Class 165 – 27 – three-car – 3 x 261 kW
  • Class 166 – 21 – three-car – 3 x 261 kW
  • Class 168 – 9 – two-car – 2 x 315 kW
  • Class 168 – 8 – three-car – 3 x 315 kW
  • Class 168 – 11 – four-car – 4 x 315 kW
  • Class 170 – 41 – two-car – 2 x 315 kW
  • Class 170 – 88 – three-car – 3 x 315 kW
  • Class 171 – 12 – two-car – 2 x 315 kW
  • Class 171 – 8 – four-car – 4 x 315 kW
  • Class 175 – 27 – two-car – 2 x 340 kW

Note.

  1. The three fields after the train class are the number of trains, the number of cars in each train and the number andsize of engines per train.
  2. All trains seem to have one diesel engine per car.
  3. All trains seem to have the same or similar Voith transmission.

There are a total of 816 trains of various lengths.
