Power Trains? Electric, diesel or hydrogen

This data-file compares diesel trains, electric trains and hydrogen trains, according to their energy consumption, carbon emissions and fuel costs. The data are presented apples-to-apples, per passenger mile, based on worked examples. Seven train routes are compared on 20 metrics overall.

Travelling by train should be 2-15x more fuel-efficient, and 3-20x less carbon intensive than travelling by car.

Electric trains are most efficient and cost-effective. The drawback is that electrifying tracks can cost c$1.4M/km. Nevertheless, we are most positive on the electrification opportunity around railways, particularly using next-generation combustion technologies.

The world’s first hydrogen trains launched in Germany in September-2018. To be cost-competitive with entry-level diesel trains requires c$12/kg hydrogen, $6/gallon diesel and a $50/ton carbon price.

Relative costs and economics can be compared by varying inputs in the file.
