    Sounds like a nice fairy tale, with zero ability to be fueled and even if you somehow did...I wonder how they are handling this little bit of potential

    Compressed gaseous hydrogen is currently the main stream for on-board storage. Maximum storage pressure varies from 35 to 70 MPa. Tanks of Type 3 (aluminium liner) and Type 4 (polymer liner) made of carbon fibre- reinforced resin are in use due to their weight. Unfortunately, fire resistance of these tanks is low. For example, reported time to catastrophic failure of Type 4 tanks is from 3.5 to 6.5 minutes [59]. The current ‘solution’ to prevent catastrophic failure of these tanks in fire conditions is to release hydrogen quickly through a thermal pressure relief device (TPRD) of comparatively large diameter of about 5 mm (before the catastrophic failure). However, this ‘solution’, which is probably acceptable in the open atmosphere, generates serious problems for life safety and property protection when a vehicle is in confined space like garage, tunnel, etc.
