Air New Zealand has cleared its runways to test both all-electric and hydrogen-powered planes. However, these advancements are on the horizon with projects like Air New Zealand trials. While it’s much smaller than today’s cargo planes, it can still carry around 200 cubic feet of cargo on nearly 250-mile-long trips. That might not seem like too far, but that’s plenty of distance for much of New Zealand air travel. Once considered cost prohibitive, hydrogen fuel planes are showing increasing promise as another possible replacement for at least some fossil fuel aircraft.
