All of the heavy-duty haulers are driven by electric motors, with battery packs that are recharged by the vehicles' on-board hydrogen fuel cells. The trucks will undergo 18 months of real-world testing under conditions that any diesel-fueled short-haul vehicle would typically encounter. Each of the two ports have agreed to dish out $212,500 from a Technology Advancement Program fund to buy the trucks. The H2-fueled big-rigs will be operated by Total Transportation Services Inc., a trucking firm that operates at both ports, while the lone yard tractor will be under the control of California Cartage Express.
