CNG – Compressed Natural Gas | Clean & Efficient Energy Fuel | Petroleum Products

CNG (Compressed Natural Gas) is one of the most efficient, economical and environmentally friendly fuel alternatives available in today’s energy market. Derived from natural gas and compressed to high pressure, CNG is widely used in transportation, industrial applications and power generation. As global industries move toward cleaner energy solutions, CNG has emerged as a key fuel supporting sustainability, cost reduction and emission control.

At PetroBNX, we supply high-quality CNG that meets international safety and performance standards, ensuring reliable energy supply for fleets, industries and infrastructure projects worldwide.

This page provides a comprehensive overview of CNG, including its characteristics, applications, advantages, specifications and global market significance.

What Is CNG (Compressed Natural Gas)?

CNG is natural gas—primarily composed of methane (CH₄)—that has been compressed to pressures typically between 200 and 250 bar to reduce its volume for storage and transportation. Despite being compressed, CNG remains in a gaseous state.

CNG is produced from conventional natural gas sources and is considered a clean-burning fossil fuel with significantly lower emissions compared to gasoline, diesel and fuel oil.

Key Characteristics of CNG

High methane content (typically >90%)

Stored under high pressure in cylindrical tanks

Odorized for safety detection

Non-toxic and non-corrosive

Lighter than air (disperses quickly in case of leakage)

High octane rating (>120)

These properties make CNG a safe, efficient and reliable energy solution for modern applications.
