It is an volatile fuel to deal with. Too much hassle in storage and maintenance. Also Easily combustible. Requires an bigger tank to store. Result, the vehicle will compromise the volume.
On the other hand companies were trying to build H-ICE engines for commercial purpose, since they have free space to set up bigger tanks.
My current suggestion will be allowing Hybrid Vehicle systems especially Range extender will have some 20KWH batteries and a small 1.2 L engine acting as generator. The primary drivetrain is Electric motor and whenever the battery runs out of juice, the engine will start to charge the battery.
Now this setup is pretty efficient. The engine will always runs at optimum RPM meaning you consume less fuel. Electric motors were highly efficient in transferring the power to wheels. So we can Motor specific advantages instant torque, regen etc.
Then We can play around with Fuel composition by doing E25.
