"Hydrogen is the big hope of the large vehicle"

Actually, no. Large vehicles are the vain hope of hydrogen types.

Large trucks will be battery electric as well, with operating and capital costs well under hydrogen trucks.

There are about 1.1 million electric buses and trucks on the roads of China already, and about 10,000 fuel cell vehicles, a rounding error.

Mining and mining equipment giants BHP, Rio Tinto, FMG and Caterpillar are all going electric and publicly dismissing hydrogen.
