Passenger vehicles account for about 16% of greenhouse gas emissions. Electric power is another 25%. The rest is industry, commercial & residential, agriculture, and other forms of transportation. It is these areas of the economy which will need hydrogen. You'll probably die of old age before there is even a whisper of a battery powered passenger plane the scale of a 787. But you may live to see a hydrogen powered passenger plane.
