I wonder if hydrogen and fuel cell would have the right P/W ratio to power this. Hydrogen fuel cell should work well at low temperatures.
However, first instinct is to not get into any aircraft with hydrogen on board ;)

... but not in terms of power/weight for the motor (or fuel cell in this case): https://en.wikipedia.org/wiki/Power-to-weight_ratio#Fuel_cel...
... You'd need about 1000lbs of weight for 200hp equivalent.
Also, I'd rather be surrounded by hydrogen than jet fuel :).
