    If it’s cryogenic, will it work in warm climates. Is it cheaper than conventional jet fuel?

      Do you really think it’s going to make much of a difference whether the ambient temperature is 37C or 0C when the hydrogen needs to be stored at -252C?

        To be fair, the ambient temperature being 37°C versus 0°C already makes a significant difference in terms of e.g. the air density and the amount of lift the wings get, how easy or hard it is to start up the engines, whether ice is a problem, etc.

        If the 15% difference in delta also translates to a 15% cost/efficiency difference, then that can absolutely make the difference in whether the technology is economically viable to apply at scale compared to its alternatives.

      We could theoretically subsidize our way through the cost difference until it becomes cheap enough to sustain through market mechanisms

      is la and san fran in summer hot enough? they have hydrogen refueling stations for cars there and afaik they work year round. if they work that is.
