Clearly we need a better solution than on-board batteries for HGV, Agricultural, and other heavy-duty uses and I'd expect this is where the impetus for hydrogen development will come from. But from a car manufacturer's perspective, I wonder just how attractive the technology is? There are something over 65 million private cars in the UK, but only around half a million touring caravans, so maybe they don't see the towing market as being that significant?
Hopefully JCB can take a technology lead in this area and then licence it for others to use.
What about builders, Ford are producing electric Transits but they won't tow a 2 tonne digger on a trailer. I did read an article where someone towed a caravan behind a full electric vehicle (sorry can't remember what vehicle) and only got 54 miles per charge. So what provision is there for when ICE is banned ?
