Compressed Natural Gas

Converting vehicles to use natural gas, particularly taxi fleets in the major urban centers, helped popularize CNG. Like oil, it is a fossil fuel, but has a few differentials:

  • it offers advantages in the cost per kilometer;
  • because it is dry, it does not lead to carbon residue accumulation on internal engine parts, increasing the useful life and the oil change interval;
  • it has low nitrogen, carbon dioxide, and sulfur emissions, contributing to improving air quality in urban centers.

Cars converted to use CNG can run on two fuels, allowing the driver to pick the best option when it comes time to fill up.

Natural gas is a blend of light compounds consisting of carbon and hydrogen, which at room temperature and at atmospheric pressure remains in the gaseous state. It is found accumulated in porous rocks underground, often together with oil, forming a reservoir.

CNG is admittedly one of the cleanest-burning fuels, with virtually no carbon monoxide emissions.

We have operations in the entire natural gas value chain: exploration and production, transportation, distribution, power generation and trade. Petrobras Distribuidora, Gaspetro, and Transpetro are a few of the subsidiaries that participate in this process.
