Why would the airport vehicles not be more efficient battery vehicles? Charging infrastructure is then of no concern, and baggage trollies and safety trucks are all low speed&#x2F;high torque applications electric vehicles we&#x27;re designed for.<p>Most pushback tugs are already transitioning to all-electric, and have a very low duty cycle (push&#x2F;pull a few aircraft, go plug in to charge).<p>The electricity-&gt;hydrogen-&gt;electricity cycle is terribly inefficient. Batteries are the answer.
