BB, do you know for certain whether the Argus engine is battery, liquid fuel, or some form of gas contained in the envelope?

Just curious at this point. Plus I wonder what sort of certification is needed to fly flammable fuel over US or foreign soil? Battery would be safer, but weight would be the obvious issue.
