regarding jose wales post about bmw just shows how good hti tech is. bmw used a liquid hydrogen to mix with gasoline that has to be kept cool or it will be lost
"To stay a liquid, hydrogen must be super-cooled and maintained at cryogenic temperatures of, at warmest, −253 °C (−423.4 °F). When not using fuel, the Hydrogen 7’s hydrogen tank starts to warm and the hydrogen starts to vaporize. Once the tank’s internal pressure reaches 87 psi, at roughly 17 hours of non-use, the tank will safely vent the building pressure. Over 10–12 days, it will completely lose the contents of the tank because of this."
no storage problem for the hyimpact
