Hydrogen by road, rail or river

Hydrogen by road, rail or river

At a time when the UK Government has pledged that greenhouse gas emissions will reach ‘net zero’ by 2050, the need for new sustainable energy sources is ever more urgent.

Double-decker buses fitted with hydrogen systems will soon be introduced onto the streets of Aberdeen and London for the first time. This is because Transport for London (TfL) and other bus operators are investing in hydrogen power as they see it as an ideal green fuel solution.

The world’s largest manufacturer of high pressure composite and aluminium cylinders, Luxfer Gas Cylinders, has supplied the hydrogen cylinders system for these double-decker buses. And it is not just on the roads that it is making a difference. Luxfer Gas Cylinders has also been working on projects to introduce hydrogen gas on our rail networks, as wel as on the river and out at sea.

Its G-Stor® H2 hydrogen cylinder system fuels the UK’s first full-sized hydrogen powered demonstrator train, for example. Unveiled at RailLive 2019, the HydroFLEX project consists of a former Thameslink electric train fitted with a hydrogen fuel system. Luxfer was approached in early 2019 by Porterbrook and the University of Birmingham’s Centre for Railway Research. From there, it designed, built and tested the storage system to the EC79 standard, installed the system on the train and performed on-site testing in less than 16 weeks. The process included Finite Element Analysis (FEA), a computerised method for predicting how a product reacts to real-world forces, vibration, heat, fluid flow and other physical effects. Finite element analysis shows whether a product will break, wear out or work the way it was designed.
