On-Train Hydrogen Storage Development Agreement

The title of this post, is the same as that of this article on Railway Gazette.

This is the first paragraph.

Alstom and automotive technology company Plastic Omnium have signed a memorandum of understanding to collaborate on ‘high-end’ hydrogen storage systems for on-train applications, with a dedicated team established to manage the technical and commercial development of ‘innovative and competitive’ equipment.

This sounds like hydrogen tanks will be efficiently designed and produced for trains and locomotives.

The designs for these important areas will probably lead to better hydrogen tanks for any application that needs one.

  1. Crash protected tanks?
    Crash protected diesel tanks were suggested for the Wrexham to Liverpool Borderlands Line. The train would be a hybrid diesel, 3rd rail. Running on electric from Bidston and back through Liverpool and Birkenhead’s centres, with the diesel tanks cocks automatically locked off. They said price was too high with demand too low.

    Nuclear waste is transported in crash proof containers, diesels tanks can be similar. Which brings us back to hydrogen in crash protected tanks running hydrogen all the way through the Liverpool tunnels – but I would rather the tanks cocks were locked off. 🙂

  2. Are large tanks pressurised to high pressures
    really the route forward?
    In August the Slovakian Rošero P company announced a Series production hydrogen FC bus that follows on from successful trials using a tank filled with a metal hydride into which the hydrogen is introduced. Reputable consultants such as Ricardo and the Fraunhofer Institute are also well advanced in their work to offer similar solutions.
    Not only does this result in compact tanks but also means that tank pressures can be reduced from the 350 – 700bar of the type specified by Alstom to a pressure of 30bars.
    As ever the developments in the EV field are dynamic.
