[–] lazynooblet@lazysoci.al 1 point 2 years ago (1 child) I thought hydrogen had the highest energy density, like it's #1 in that metric. permalink fedilink source parent hideshow 2 child comments replies: [–] FuglyDuck@lemmy.world 2 points 2 years ago By mass, sure, but not by volume; and that usually doesn’t take into account the mass of the tanks, and hydrogen is rather difficult to keep from leaking. In cars we’re more concerned about volume than mass, in which it performs very low- aluminum as a fuel actually leads that (but is … impractical…) For cars, amonia would be the better choice and can be synthesized at home fairly easily. It’s still fairly low energy, though. About the same as hydrogen permalink fedilink source parent
