I've personally heard rumors that it will consist of both a jet engine
directly burning hydrogen and a fuel-cell powered electric fan. I'm a
little skeptical.
On the other hand, apparently electric aircraft do have a ton of commercial
promise for short-legged hops for minimal numbers of passengers or light
cargo to remote communities where relatively low speed is basically
irrelevant but fuel and maintenance costs are significant.

But if you've got a battery, why bother with the fuel cell?

Can fuel cells deliver the high currents necessary to drive such large
motors practically speaking in a flightweight configuration and give decent
range comparable to its jet fuel counterpart?
Carbon madness, will level heads ever prevail?

Liquid hydrogen is at the core of Airbus’ exploration of the
possibilities for decarbonizing commercial aviation, primarily as a fuel
for zero-emission flight. But across Europe and UK, researchers are
investigating the potential for also using the cryogenic fluid to cool
propulsion systems to...
