Sparking A Revolution

The title of this post is the same as that of an article in Issue 898 of Rail Magazine.

The sub-title is.

When it comes to powering a zero-enissions train with no overhead line infrastructure, battery power is clearly the answer, according to Hitachi.

These are the first three paragraphs.

Over the next decade around 1,000 diesel-powered vehicles will need to be replaced with vehicles that meet emissions standards.

Hitachi, which has been building bi-mode trains for the UK since 2012, and electric trains since 2006, says that retro-fitting old vehicles alone will not be good enough to improve capacity, reliability or passenger satisfaction.

Battery power is the future – not only as a business opportunity for the company, but more importantly for the opportunities it offers the rail industry.

Speaking is Andrew Barr of Hitachi Rail.

Some important points are made.

  • Hitachi has identified various towns and cities, where battery trains would be useful including Bristol, Edinburgh, Glasgow, Hastings, Leeds and Manchester.
  • Andrew Barr says he gets a lot of questions about battery power.
  • Battery power can be used as parts of electrification schemes to bridge gaps, where rebuilding costs of bridges and other infrastructure would be too high.
  • Battery trains are ideal for decarbonising branch lines.
  • Batteries could be fitted to Class 385, 800, 802 and 804 trains.

Hitachi would like to run a battery train with passengers, within the next twelve months.

The article also gives the specification of a Hitachi battery train.

  • Range – 55-65 miles
  • Performance – 90-100 mph
  • Recharge – 10 minutes when static
  • Routes – Suburban near electrified lines
  • Battery Life – 8-10 years

These figures are credited to Hitachi.

Hitachi are also thinking about tri-mode trains.

  • Batteries could be installed on Class 800-802/804 trains.
  • Battery-only power for stations and urban areas.
  • 20% performance improvements or 30% fuel savings.

These is also credited to Hitachi.

Costs And Power

This is an insert in the article, which will apply to all applications with traction batteries.

This is said.

The costs of batteries are expected to halve in the next five years, before dropping further again by 2030.

Hitachi cites research by Bloomberg New Energy Finance (BNEF) which expects costs to fall from £135/kWh at the pack level today to £67/kWh in 2025 and £47/kWh in 2030.

United Kingdom Research and Innovation (UKRI)  is also predicting that battery energy density will double in the next 15 years, from 700 Wh/l to 1,400 Wh/l in 2035, while power density (fast charging) is likely to increase four times in the same period from 3 kW/kg now to 12 kW/kg in 2035.

In Batteries On Class 777 Trains, I quoted a source that said that Class 777 trains are built to handle a five tonne battery.

I estimated the capacity as follows.

Energy densities of 60 Wh/Kg or 135 Wh/litre are claimed by Swiss battery manufacturer; Leclanche.

This means that a five tonne battery would hold 300 kWh.

Hitachi’s figures are much higher as it looks like a five tonne battery can hold 15 MWh.

Batteries will be going places on Hitachi trains.
