Which of the following is a primary use of CNG?

Compressed Natural Gas (CNG) is primarily used as a fuel for vehicles. It is an alternative to gasoline and diesel, chosen for its environmental benefits, including lower emissions of harmful pollutants and greenhouse gases. CNG is particularly attractive in the automotive industry for fleets, public transportation, and personal vehicles. Many municipalities and companies adopt CNG vehicles as a way to reduce their carbon footprint and comply with stricter emissions regulations.

While CNG can be utilized in various sectors, including residential heating and potentially some marine applications, its predominant application remains in powering internal combustion engines in vehicles. This makes it a significant part of the conversation around sustainable and alternative fuels in the transportation sector. In contrast, aerospace manufacturing may involve numerous advanced materials and processes, while residential heating is more commonly associated with natural gas or heating oil, making them less relevant as primary uses for CNG.
