Not sure if this has been mentioned earlier - I heard on Radio 4 a few days ago about a new storage technology for hydrogen - early days yet although it sounds potentially a game changer for storing and use of hydrogen in vehicles. The link is on the BBC website
https://www.bbc.co.uk/news/science-environment-52328786 - it involves using a new sponge like metal technology that can store masses of hydrogen in a relative small area. It sounds safer than the current storage systems.
Like others on this forum I personally think electric cars are a dead end (too expensive, not really environmentally friendly, and could not replace the current number of vehicles used worldwide or in the UK) - unless we want to cosy up to China for the next 60 years as they control access to many of the chemicals required to make electric vehicles storage batteries, plus the terrible conditions of mainly very young children used to mine the metals required, in some of the African countries.
