Hydrogen fuels can be reformed into many different fuels, for Aviation weight and volume are critical, when land transport is fully non fossil fueled liquid fuels will still be used for Aviation, unless some yet unknown technology is discovered. Safety is a different matter, it is not possible to segregate passengers and compressed fuel in an airline, any fault would destroy the whole thing so either you accept that risk or forget it.
Limited range light aircraft have possibilities either Battery powered or Fuel Cell electric, wether that is within the price range of recreational pilots is another matter
