As the government and people are transitioning towards cleaner fuels, they are either choosing LPG or CNG. But according to reports LPG is a much better choice than CNG or natural gas. Why is that?
If we go by definition, LPG stands for "Liquified petroleum gas", while CNG stands for "Compressed natural gas". The difference in abbreviation shows, one is a by-product of petroleum filtration, while another is natural gas that is compressed to be filled in cylinders.
The primary difference between LPG and CNG lies in the components that make up these fuels. While CNG is primarily Methane, LPG is made of propane. According to the World Health Organization, LPG does not produce particulate matter while methane produces PM 2.5, making it more harmful than LPG.
Apart from the composition, these two liquefied gases are different in a lot of aspects, some of which are discussed here in detail.
LPG is comparatively heavier than CNG, which is why, most smoke production after burning LPG remains on the ground rather than accumulating in the atmosphere and causing increasing levels of CO, CO2, NOx, and SOx.
LPG does not diffuse in the atmosphere like CNG, rather, it alarms the people about leakage before time, so proper safety measures are taken. LPG and CNG both are odorless gas but in LPG, Ethyl Mercaptan is added that smells like a "rotten egg", hence helping in alarming the people who are using the gas.
LPG is more cost-effective than CNG. LPG produces twice the energy of CNG at the same cost, hence making it more effective than natural gas. As CNG cost depends on local fuel prices, it can fluctuate a lot from place to place, while LPG has similar costs across the nation.
LPG has a high calorific value which ranges from 90 to 95 MJ/m3 whereas, CNG's calorific value ranges between 35-40MJ/m3. The difference in calorific value shows the flammability of each gas.
LPG-run vehicle has better ignition than CNG-run vehicles. Moreover, a high calorific value depicts there won't be any residual burning.
LPG is useful in residential, commercial, and industrial applications, while the use of CNG is quite limited. CNG is mostly useful as a vehicular fuel, while LPG can be used as cooking fuel, industrial fuel, and also as a vehicular fuel.

Moreover, LPG has replaced the use of chloroform carbon in refrigerators, thus helping free the world from the growing pollution caused by chloroform carbon.
There is an extensive network of LPG and CNG. However, you can buy LPG easily from any LPG gas distributors in your area. From LPG filling centers to buying a cylinder that fits your requirements, you can get anything from the market with ease.
As we have already discussed why LPG is a better fuel than CNG, it is important to consider, that LPG is helping in creating a smooth transition from gasoline to cleaner energy fuel. SHIVGAS is a private gas agency, which is bridging the gap between demand and supply, to help in the transition.
By producing a minimal amount of particulate matter, it is creating a transition in energy fuel and allowing the next generation to dream of a cleaner future. By adapting to more and more vehicles, India is transitioning from LPG to Gasoline.

LPG (Liquefied Petroleum Gas) is a mixture of propane and butane, while CNG (Compressed Natural Gas) is primarily methane. LPG is stored in liquid form, whereas CNG is stored as a gas under high pressure.
CNG is generally considered more environmentally friendly because it produces fewer greenhouse gases and pollutants compared to LPG.
CNG is typically cheaper than LPG in terms of cost per energy unit. However, the overall cost-effectiveness can vary depending on local fuel prices and vehicle efficiency.
Both fuels are relatively safe when handled properly, but CNG is less flammable and has a narrower flammability range compared to LPG. Proper storage and handling are crucial for both fuels to prevent leaks and accidents.
Some vehicles can be converted to run on either LPG or CNG, but it requires different conversion kits and storage systems. It's important to consult with a professional before making any modifications.
Availability varies by region, but LPG tends to have wider distribution networks globally, while CNG is more common in areas with natural gas infrastructure.
CNG generally offers higher fuel efficiency in terms of cost per kilometer, but LPG provides higher energy content per unit volume. The best choice depends on the specific vehicle and usage patterns.
