   We could send up water, then just let solar array-powered electrolysis   
   slowly do its magic to make the fuel. Two years for a bag of fuel? No   
   problem, no rush.   
      
   That way no volatile components in the launch. You could freeze the   
   water, and use it as part of the structure of the launch vehicle to   
   reduce weight. Alternate launch techniques such as rail guns? The   
   payload would certainly tolerate the G's.
