AUSTIN, Texas — Transportation experts agree that there is no single answer for which alternative power source is best to carry the trucking industry to a zero-emission future, especially as questions remain about fueling and power infrastructure, and access to raw materials.

In particular, there are serious questions about the volume of critical minerals needed for battery-electric vehicles, and whether the needed recharging or refueling infrastructure will be ready for prime time.

Despite the concerns, there seems to be optimism that both hydrogen and battery-electric could each offer a solution in their own right, according to a panel of experts speaking at an Oct. 15 educational session at American Trucking Associations’ 2023 Management Conference and Exhibition.
