How much would that cost with conventional fuel?

[TylerE]

A lot. Perhaps 75 gallons/hr. Jet fuel is currently a about $1/gallon.

Even a much smaller plane like a 172 can easily burn $50/hr just in fuel. Much lower flow rate, but it’s leaded a gas at about $4.50/gal

Way more than that these days. There’s only one supplier of 100LL, and even they don’t want to be in the business anymore.

Its not just the fuel cost, maintenance of electric motors is substantially cheaper. Plus, there's no need to transport and store specialty Avgas.
