I bet trucks will still run on fossil fuel. Probably LNG.
I doubt it. LNG has some serious issues. Since it is in liquid form it has to be at extremely low temperatures. It is nearly impossible to make a tank that can hold the stuff and keep it at low temperature. The buses and other large commercial vehicles that use LNG deal with this problem by simply allowing the stuff to boil off and there is a pressure valve that releases it into the atmosphere. So if you let an LNG vehicle sit for a few days it will be out of fuel even if you never drove it. This isn't much of a problem for a bus or something that is driven every day. But the consumer would never put up with this issue.
CNG, on the other hand, is a good alternative for pickup trucks. Better yet, a hybrid-electric pickup that runs on CNG.
