The US Office of Naval Research has successfully flown a drone for two entire days using a tank filled with liquid hydrogen. The previous experiment used a hydrogen fuel cell as its power source, flying for a then record time of 26 hours.




The new test used a cryogenic storage tank filled with liquid hydrogen, flying for 48 hours, breaking the previous record by nearly an entire day. We should expect this technology to continue to impress, just give it a few more years.
