Didn&#x27;t consider that. Thanks!<p>EDIT: Maybe there are some improvements for storage available that don&#x27;t make sense on Earth given H₂ prices? A magnetic containment field, perhaps? Or whatever chemistry shenanigans are used for hydrogen fuel cells? You would be trading the time factor for mass and volume (the latter doesn&#x27;t matter that much in space, and could even help with aeroinsertion), but it may still add up moneywise.
