Concerned about the future of our planet and eager to make small but impactful changes, you have been considering buying a bus powered by alternative fuel. However, when researching the web in search for the benefits of compressed natural gas (CNG), one of the most common alternatives to traditional fuel, you became overwhelmed by all the contradictory information. Here are some myths about CNG that you might have encountered!
MYTH: CNG buses are more expensive than diesel buses
Although CNG buses do in fact cost from 25 to 50 thousand dollars more than your typical diesel bus, the fuel for this alternative type of vehicle costs less than diesel fuel. Because of significant savings that accumulate over time, it is estimated CNG bus-buyers will get a return on their investment in three years.
MYTH: Maintenance of CNG buses costs more than that of diesel or hybrid-electric diesel buses
Since CNG buses use spark plugs, they require periodic ignition maintenance, which is not the case with diesel engines. On the other hand, CNG type of vehicle has a cleaner combustion process that causes less engine wear, making it more durable and saving a significant amount of money, money that diesel users would most commonly spend during a mid-life rebuild of the diesel engine. The CNG engine uses lubricating oil a lot less in comparison to the diesel engine, which means the need for an oil change will be less frequent. This will also help save money in the cost of filters, hazardous waste disposal, oil, and human labor. Since CNG does not create particulate matter buildup, there is less need for cleaning in the engine compartment as well.
MYTH: CNG buses emit more methane and thus more greenhouse gases than diesel engines
During combustion, natural gas has lower carbon dioxide emissions in comparison to diesel. Even though CNG buses emit higher levels of methane, when taking into account the entire fuel cycle of both types of engines, including the production of fuel, CNG buses seem to have the total greenhouse gas emissions levels very similar or even lower than diesel buses.
