Benefits of Compressed Natural Gas (CNG)
Compressed natural gas (CNG) has long been touted as a cleaner, cheaper, and more sustainable alternative to petrol. While it is not new to Nigeria, CNG has gained renewed attention with the federal government’s push for its adoption. Here are the key facts Nigerians should consider:
Cost Efficiency: On average, CNG is significantly cheaper than petrol. It can offer savings of up to 73% compared to petrol, which makes it attractive for vehicle owners struggling with rising fuel costs. As more filling stations convert to offer CNG, these savings will become even more accessible.
Environmental Benefits: CNG produces up to 30% fewer greenhouse gas emissions than petrol. This reduction could significantly improve Nigeria’s air quality, particularly in congested urban areas like Lagos, where emissions are a major public health concern.
Local Production: Nigeria is home to one of the largest natural gas reserves in the world. Unlike petrol, which is heavily imported and affected by global price fluctuations, CNG could be produced domestically at lower costs, providing more control over pricing and supply.
While petrol may not disappear completely in the near future, CNG is certainly going to take a substantial market share. If the trend continues, it’s not outrageous to expect that petrol could eventually become a minority fuel, much like coal today.

CNG Is Leading The Change
The rise of CNG in Nigeria is undeniable, and its benefits; cost savings, environmental sustainability, and local availability make it a strong contender to replace petrol in the future. However, for now, petrol still holds the dominant position, largely due to its existing infrastructure and widespread usage.
That said, as Nigeria continues to invest in CNG infrastructure and public awareness grows, the country is likely to see a significant shift towards CNG over the coming decade. Whether or not this signals the death of petrol remains to be seen, but one thing is clear: the future of transportation in Nigeria is evolving, and CNG is leading the charge.
It’s common for people to associate CNG with the risk of explosions, much like LPG, but the reality is that CNG is fundamentally different from LPG and significantly safer.
Key Differences Between CNG and LPG
- CNG (Compressed Natural Gas) is primarily methane, which is lighter than air. If a CNG leak occurs, the gas rapidly dissipates into the atmosphere, reducing the risk of accumulation and explosion.
- LPG (Liquefied Petroleum Gas), on the other hand, is heavier than air, meaning that if it leaks, it tends to pool on the ground or in low areas, creating a higher potential for explosion if ignited.
Addressing Fear of Explosions:
- CNG Tanks Are Extremely Strong: CNG is stored in high-pressure tanks designed to withstand extreme conditions, including collisions. These tanks are built to high safety standards and undergo rigorous testing, making them more robust than traditional petrol tanks.
- Safety Mechanisms: In the event of an accident, CNG tanks have special safety valves that automatically release pressure if it gets too high, preventing dangerous ruptures.
- Non-Flammable in Air: CNG requires a very specific air-to-gas ratio to ignite, which makes accidental explosions highly unlikely. Petrol vapors, by comparison, are far more volatile.
How CNG Differ from Petrol in Accident:
In most cases, petrol leaks can lead to dangerous spills, with fuel spreading and catching fire easily. CNG, on the other hand, simply disperses into the air if there’s a leak, making it far safer in accident situations.
Before converting your car to CNG, it’s essential to weigh both the benefits and challenges. Here’s a comprehensive breakdown:

Advantages of CNG Vehicles:
- Significant Fuel Savings: You can reduce fuel costs by over 70%. The savings will eventually cover the cost of conversion.
- Cleaner Engine and Prolonged Lifespan: CNG burns cleaner than petrol, leading to less carbon buildup, which helps extend engine life and maintenance intervals.
- Less Exhaust Wear: CNG’s combustion is cleaner, meaning your vehicle’s exhaust system and catalytic converter will last longer.
- Better Factory Fitted Performance: Vehicles with factory fitted CNG systems often have superior performance compared to retrofitted vehicles.
- Environmentally Friendly: CNG produces fewer pollutants like carbon monoxide and nitrogen oxides, making it a more eco-friendly fuel.
- Higher Ignition Temperature: CNG has a higher ignition temperature than petrol, making it safer and less likely to cause accidental fires.
CNG vs. PMS Vehicle Explosion: Which is Worse?
The concerns around explosions are common for both CNG (Compressed Natural Gas) and PMS (Premium Motor Spirit) vehicles, but the risks differ significantly between the two.
CNG Explosion Risks:
- Higher Ignition Temperature: CNG has a higher ignition temperature (540°C) compared to petrol, making it less likely to ignite under normal conditions.
- Pressurized Cylinders: CNG is stored in highly durable and tested cylinders. These are designed to withstand high pressures and come with safety valves that release gas slowly in the event of a leak, reducing the likelihood of an explosion.
- Lower Flammability Range: CNG has a narrow flammability range, which means it needs very specific conditions to combust.
- Safer in Accidents: In case of an accident, CNG tends to dissipate quickly into the atmosphere due to its light weight, minimizing the risk of an explosion.
PMS Explosion Risks:
- Lower Ignition Temperature: Petrol has a much lower ignition point (around 247°C), meaning it can ignite more easily when exposed to a heat source.
- Higher Volatility: Petrol is more volatile and creates heavier vapors, which can pool and lead to more significant explosions in enclosed spaces.
- Spillage Risk: In the event of an accident, petrol can leak and spread over a wide area, increasing the chance of fire or explosion.
Conclusion:
While both CNG and petrol carry explosion risks, CNG vehicles are generally considered safer due to the higher ignition point, secure storage tanks, and lower flammability. Petrol, being more volatile, presents a greater explosion hazard in the case of fuel leaks or accidents.
