Storage of large quantities of hydrogen is a pain and also heavy (which matters a lot on a plane), so if you really want clean fuel, then synthetic hydrocarbons make more sense on a plane than hydrogen.
- angiosperm 3y agoStorage of LH2 is not, in fact, heavy. Rockets are even launched carrying it. Management of bulk LH2 is a chore, but is mature technology. The value proposition of LH2 as aircraft fuel is such that, in any market where LH2 airframes come into service, kerosene craft will be immediately wholly unable to compete.
- PeterisP 3y agoAh, I was thinking more about hydrogen fuel cells and gaseous hydrogen (which I've seen discussed for the plane replacements) not cryogenic liquid hydrogen.
