Cars that run on natutral gas are a gas engine with a new tank and a modified intake manifold. It is not a complicated conversion, butit does require certification and a regular tank testing like any gas bottle.
LNG burns very clean compared to gas or diesel. The exhaust is almost entirely CO2.

Hydrogen combustion engines can also be built, although that solves none of the problems of hydrogen that I can see.
