Alstom Calls For Hydrogen Rail Fleets In The UK

The title of this post, is the same as that of this article on H2View.

These are the first three paragraphs.

Alstom has called for a £10bn investment programme in UK rail and mass transit systems, through which it would like fleets of clean, zero emission hydrogen trains to replace pouting diesel alternatives.

Titled: The UK’s New Green Age; A Step Change in Transport Decarbonisation, the report states that 300-400 hydrogen trains could be launched simply with a like for like replacement of diesels and would deliver huge environmental benefits.

The report was released after recent research revealed that the UK is lagging behind surrounding countries in comparable infrastructure. For example, France has over double the number of mass transit systems as the UK, whilst Germany has four.

There is a rapidly developing argument between the proposers of hydrogen and battery trains.

Consider.

  • Both types of train can ve a straight replacement for diesel trains, often with very little modification to stations.
  • As both hydrogen and battery trains have electric traction, they could have improved performance, so tracks and signalling might need upgrades to make full use of that performance to provide a better service for passengers.
  • Hydrogen trains will need a refuelling strategy.
  • Hydrogen trains need to carry a large tank of hydrogen.
  • Battery trains may well need charging systems or extra lengths of electrification for charging.
  • The UK will have plenty of green hydrogen and zero carbon electricity.

I also believe that hydrogen and battery trains designed from scratch will be much better than conversions of existing stock.

Conclusion

I think the environment will win this argument.

I can see cost and local circumstances deciding, whether to use battery or hydrogen trains.

For instance, Ipswich and Norwich, where there are an electrified main lines, might become battery train hubs, whereas Middlesbrough, where there is a plentiful supply of hydrogen, might use hydrogen trains for local services.
