Industry Urged To Decide On Alternative Technology

The title of this post, is the same as that of this article on Rail Magazine.

This is the first paragraph.

The rail industry needs to decide on the right approach to alternative technology as soon as possible, to ensure the industry can continue to reduce emissions.

Speaking to the All-Party Parliamentary Rail Group, Anthony Perratt of the RSSB, outlined how there was a huge opportunity to replace ageing Sprinter trains with new units powered by alternative energy sources like batteries and hydrogen.

The Size Of The Opportunity

Sprinter trains in service of stored in the UK include.

These add up to 516 trains, with a total of 1035 cars.

In the Wikipedia entry for the Class 710 train, this is said.

TfL announced that it had placed a £260m order for 45 four-car Bombardier Aventra EMUs.

This works out at nearly £1,500,000 for each car of a modern train.

This means that replacement of the Sprinters, with new independently-powered trains, would be project of the order of £1.5billion.

That is a market, that would be very much desired by a train builder.

Battery, Diesel Or Hydrogen Power?

Diesel power is probably not a good idea, if it can be avoided.

The following points about hydrogen- and battery-powered trains should be noted.

  • Most hydrogen-powered trains are battery-powered trains, with a hydrogen fuel-cell to recharge the batteries.
  • Battery technology is improving fast.
  • Systems to rapidly charge batteries will be available in a couple of years.
  • Battery-powered trains can use existing electrification to charge the batteries.
  • Hydrogen-powered trains may need a large tank for the hydrogen, which limits passenger capacity.
  • Hydrogen-powered trains need a refuelling structure, which may be more difficult to install, than a charging system for battery trains.

I feel that innovative engineers will be able to find ways to enable battery-powered trains on routes that need independently powered trains.

Conclusion

I don’t think, that we’ll see many long-term applications of hydrogen-powered trains in the UK.
