1. A method of retrofitting a diesel-powered mining haul truck with a hybrid hydrogen fuel cell/battery-based powerplant, comprising:
removing, from a frame of the haul truck, (a) an engine and an alternator from an engine bay, (b) a diesel tank from a first wheel pocket, and (c) a hydraulic fluid reservoir from a second wheel pocket to create a plurality of first available volumes;
installing the hydraulic fluid reservoir in a rear axle pocket; and
installing at least a portion of a fuel cell system, a battery system, or a hydrogen storage system (HSS) in at least one of the first available volumes.
