Hydrogen-powered trains are arguably the greenest trains out there. “Mini power stations on wheels”, is how Alex Burrows from the University of Birmingham describes them. He is the project director for the ‘Hydroflex’ train which was showcased at an event in the West Midlands. Unlike diesel trains, hydrogen-powered trains do not emit harmful gases, instead using hydrogen and oxygen to produce electricity, water and heat. A quarter of the UK’s trains run solely off diesel. The government wants them all gone by 2040. Two thirds of our rail lines do not have overhead cabling which electric trains need to run. Regional routes which carry relatively few passengers are unlikely to be electrified soon. And that is where hydrogen trains come in. The hope is that they will be carrying passengers in the UK in two years.
