Liquefied Petroleum Gas (LPG)

  • LPG is a mix of different gases. LPG is mostly made up of butane and propane, both of which remain liquid when they’re compressed.
  • LPG is much less expensive than other types of natural gas.
  • One of the biggest problems with LPG is that if it leaks, air will collect underneath the car and could lead to an explosion when the ignition is started.
  • It can take up to 20 minutes to refuel a sedan with LPG.
  • A car crash could ignite the tank easier than on a traditional car.

Compressed Natural Gas (CNG)

  • CNG is 50% more expensive than LPG, but it’s still cheaper than other oil-based fuels.
  • CNG is much safer than LPG since it’s so light.
  • CNG can withstand impact of up to 50 mph from trucks.

How Cars that Run on Natural Gas Work

Wondering how natural gas cars work? You’re not alone. Here are the basics of these unique cars:

  • Natural gas vehicles utilize either liquefied natural gas or compressed natural gas instead of other fossil fuels.
  • Some cars are bi-fuel vehicles, meaning that they can run on either gasoline or natural gas.
  • Cars that currently run on gasoline can be converted to run on natural gas.

Limitations and Drawbacks

Not every part of owning a natural gas car is positive. They have their drawbacks, too, and here are some of them:

  • Natural gas cars can’t hold a lot of fuel at once, which means you’ll have to fill up more frequently.
  • Natural gas isn’t available at every, or even many, gas stations, which makes it hard to drive long distances in a car that only runs on natural gas.
  • The natural gas is stored in cylinders in the car’s trunk, which greatly reduces trunk space. This makes it difficult to fill up your car with baggage for a long road trip or vacation. However, some cars have the natural gas tanks location under the car’s body, keeping them out of the way and leaving the trunk empty.
