It's also the smallest molecule out there (H2) and has to be stored at pressure (or 'dissolved' into some porous medium), so will find its way through the tinyest of holes, making the task of sealing and testing all joints between manufacture, storage, transport and final use all much more of a challenge. Add in that it's odourless and explosive and you can see it is much more hazardous than the petrol/diesel we handle in unpressurised liquid form. Expect they'll have to add an odour to it like they do with LPG, but the leaky molecule issue will persist regardless.
