Natural Gas Vehicles: Pros and Cons - CarsDirect
Just like when driving with a car using gasoline, there are pros and cons to driving natural gas vehicles.Although the greenhouse gas emissions emitted by a natural gas vehicle is less than that of a gasoline vehicle, natural gas—or CNG as it is known—is still a fossil fuel and therefore a non-renewable resource.
How is methanol made into gasoline?
The Mobil process further converts the methanol into gasoline, first by dehydrating it into a dimethyl ether (CH3OCH3 + H2O) then further dehydrating it over a zeolite catalyst, to yield gasoline.The backend of the process, turning methanol into gasoline, is very energy intensive. Citing poor economics, Mobil in 1996 stopped gasoline production at the New Zealand plant, which continued to produce methanol. Primus's Boyajian says that they have figured out how to improve on the Mobil process to make it more energy efficient.
Is compressed natural gas better than LNG?
In Ryder's universe, compressed natural gas seems to have the upper hand versus LNG so far. There's more CNG filling stations (though not enough), and CNG is easier to pump and to store. LNG is a more energy-dense fuel than CNG, (meaning your truck can go farther on one fill up), however because LNG is a –260 degree Fahrenheit liquid it must be stored in heavily insulated tanks. Even the thickest insulation can't keep the LNG that cold indefinitely. And there's another problem. As one speaker explained, you don't want to leave a truck filled with LNG sitting in the parking lot for any length of time because when the engine's not running the tanks will automatically vent evaporating LNG — i.e. pure methane -- straight into the air. As a greenhouse gas methane is 24 times worse than carbon dioxide.

Type II is a thinner metal tank wrapped around the middle with a fiberglass or carbon composite. Type III is a thinner metal tank fully wrapped in composite. Type IV is a plastic tank fully wrapped in carbon-fiber composite--very lightweight, but it comes at a hefty price.
How to convert a gas engine to natural gas?
It doesn't take much besides a new fuel tank to convert a gasoline-burning engine to one that also runs on natural gas. Attached to the fuel tank [1] is the regulator [2], which reduces tank pressure from 3600 psi to 125 psi. Fuel is then fed to a parallel fuel rail [3] and to new, secondary injectors plugged into an adapter [4]. A wiring harness [5] plugs into the factory engine-control unit and intercepts throttle information, sending it to a new fueling computer [6], which slightly alters the data and passes it to the CNG injectors [7] through a parallel wiring harness [8].
