\"Hydrogen, on the other hand, is more fiddly to deal with, and less energy-efficient from an energy generation to power output perspective, but it offers significant energy density advantages when used in a fuel cell electric setup. And those energy density advantages are compounded when the hydrogen\'s stored cryogenically as a liquid.\
\
Back in April 2019, South Korean company MetaVista mounted a 6-liter liquid hydrogen cylinder and an 800-W Intelligent Energy fuel cell power module to a drone and recorded what stands as the longest ever multirotor flight at an eyebrow-raising 12 hours, 7 minutes and 5 seconds\"
