Would it make sense to use hydrogen fuel to further decrease the weight?
- tachyonbeam 6y agoAFAIK hydrogen is hard to store, so your storage tank might be pretty heavy. It also has lower energy density than gasoline/kerosine.
- baybal2 6y agoCost-wise, no
- semi-extrinsic 6y agoThere have certainly been cost effective hydrogen powered long distance drones. One potential benefit is that you can run fuel cells, which are silent and quite a bit more efficient than a two-stroke driving a generator. OTOH, getting similar energy density is challenging, as others have said. Although you can come quite close with liquid hydrogen, if you can live with a fuel that's not storable for long times at small quantities in the field.
- Tomminn 6y agoSince hydrogen is very low density you'd pay through the nose in terms of an increase in drag and a decrease of max wind tolerance.

- jlcortex 6y agoEquivalent hydrogen multirotors at this stage do not have the payload capacity of a hybrid fuel-electric drone. They might be a great solution in the future, but the technology is not there yet.
