Having worked for one of the developers supplying FC power units for fork trucks I can say that large customers in NA operating on 2-3 shifts per day are moving to hydrogen over battery trucks due to increased productivity. Furthermore, they will convert their entire fleet, even class 3s, to FC so they can totally eliminate battery charging infrastructure. A large distribution centre with FC fleet will move more goods for less money than the same centre running battery trucks. In the end this is the only metric that counts for them.

For these customers, lithium does not add anything significant over LA batteries as they have higher upfront costs and still require charging (i.e. downtime). Fast charging sounds good in theory but, as someone pointed out the power required to charge in 5 min is massive and with a fleet of 200 trucks is completely unworkable not to mention the electrical peak demand charges.

Battery electric will still have their place and will continue to be used on smaller fleets or 1 shift operations; a significant part of the overall market. They will also continue to be used in Europe as the large, multi shift distribution centres are less common and hydrogen is more expensive due to lack of Liquid H2 infrastructure (thanks NASA!).
