I suppose for the same reason I’m not crazy about gas grills..I’m afraid of a collision/exposion. Let me know when they make the tanks leakproof/crash proof.
I know that sounds a bit paranoid..but even gas grills make me nervous (have had/seen a flareup or two). So, I still use charcoal.
I understand that in South Korea a lot of their vehicles are running on hydrogen. Very explosive! But I have not seen one report of any of these hydrogen tank explosions. Reckon none are getting involved in wrecks?
When I was growing up in East Texas, quite a few people ran their pickups and cars on propane, apparently as safely as gasoline.
Most likely CNG or LNG tanks are being designed to withstand severe collision and puncture incidents. There are many 18 wheelers and trains hauling 5,000 or 10,000 gallon tanks of LPG/LNG everyday.
I use charcoal because I want my food taste like is been Barbecued.
