Energy density, storage, and delivery are major stumbling blocks with hydrogen
Can you imagine trusting your typical backwards baseball cap wearing yoof, to fill his car up with hydrogen gas....
Hindenburg anyone
The Swiss (and other nations) and Hyundai are carrying out a test using a small fleet of HGV’s so I have a feeling the issues around a 1930’s airship May have been resolved.
I believe the connector from pump to tank has been designed to deal with numpties who I hasten to add we already trust to use one of the most flammable liquids known which also produces flammable gas and can be put into take home containers
