Heat From HS2 Trains Will Warm 500 New Homes

The title of this post is the same as that of an article in today’s copy of The Times.

This is the third paragraph.

HS2 Ltd, the company building the  £56 billion high-speed line, has produced plans to recycle waste heat from the electric motors and brakes of trains approaching and departing from a £1 billion “super hub” station at Old Oak Common, near Willesden, North West London.

Other points from the article include.

  • Five air source heat pumps will be used.
  • , Each heat pump costs around £11,400.
  • The carbon footprint of each house could be reduced by a fifth.
  • Plans are at an early stage, but the technology is proven.
  • Similar technology could be applied to tunnels on the Northern routes to Leeds and Manchester.

I can only see one problem with the idea.

The companies bidding to make the trains for HS2, will design trains with the following features.

  • Highly-efficient aerodynamics of both trains and tunnels, to reduce energy losses and power required to move the train.
  • Regenerative braking to onboard electricity storage.
  • Train systems like air-conditioning, lighting and toilets that use smaller amounts of electricity.

HS2 will also draw heavily on proven  innovative ideas from similar projects, to reduce the energy used by the trains, whether in the tunnels or the open.

But, I would also suspect that HS2’s proposal is based on a good assessment of the energy dissipated by the trains.
