These guys — https://ffi.com.au/ — are building Green Hydrogen powered everything, including starting with those massive dump trucks. Batteries are too heavy for this application. They are using batteries in an ‘Infinity train’ though; their mine is higher than their port, empty train uses batteries to climb the hill, filled with 40KT of iron ore, coasts down hill and regeneratively more than charges up the batteries.is there ev mining equipment..?
