Several industrial sectors have utilized Compressed Natural Gas (CNG) as an energy source. However, for large-scale energy needs that operate continuously, CNG still faces a number of challenges, such as limited storage capacity, less efficient distribution over long distances, and supply limitations in locations not yet connected to the gas pipeline network.
These conditions are pushing industries to look for more efficient alternatives to maintain production continuity while optimizing operational costs.
One option that is widely being considered is Liquefied Natural Gas (LNG) because it offers better storage and distribution efficiency for large-scale energy needs.
What Are LNG and CNG?
LNG and CNG both come from natural gas dominated by methane (CH4), but are processed in different ways.
LNG is produced through a liquefaction process by cooling it to around -162°C to significantly reduce the volume of the gas, while CNG is obtained by compressing the gas to a pressure of around 200 to 250 bar without converting it into liquid form.
These different processes give both fuels different characteristics in terms of storage, distribution, and usage. Below are the differences between LNG and CNG across various aspects.
| Aspect | LNG | CNG |
| Form | Liquid | Compressed gas |
| Production Process | Cooled to approximately −162°C | Compressed to approximately 200–250 bar |
| Storage Volume | Reduced by approximately 600 times compared to natural gas | Reduced much less than LNG |
| Volumetric Energy Density | Higher | Lower |
| Tank Type | Cryogenic tank | High-pressure cylinder |
| Transportation Efficiency | Highly efficient for long-distance transportation | Better suited for local distribution |
| Distribution Infrastructure | Can be transported by LNG carriers or LNG trucks to areas without pipeline networks | Generally relies on pipeline networks or distribution using high-pressure cylinders |
| Typical Industrial Applications | Large industries, power plants, smelters, mining operations | Vehicles, small- to medium-scale industries, areas near gas pipeline networks |
| Main Advantage | Efficient for large-scale storage and distribution | Practical for local and small- to medium-scale applications |
These differences show that LNG and CNG are designed for different needs. CNG is generally more suitable for local use or small to medium-scale energy needs, while LNG is more effective for industries with large energy consumption.
For this reason, the choice between LNG and CNG should be based on the operational needs, location, and energy consumption scale of each industry.

Why Is LNG Superior to CNG for Industrial Needs?
LNG is considered superior for many industrial needs because it offers better storage and distribution efficiency, especially for operations with large and continuous energy consumption.
These advantages impact not only the technical aspects, but also deliver business value through logistical efficiency, energy supply reliability, and the potential for operational cost savings.
Higher Energy Density for More Efficient Operations
LNG has a higher volumetric energy density compared to CNG because it is stored in liquid form.
With a smaller storage volume, tanks can hold a larger amount of energy, so delivery frequency can be reduced and the operational needs of large-scale industries can be met more efficiently.
More Flexible Energy Distribution for Remote Locations
LNG can be distributed using vessels and cryogenic trucks, so it does not depend on a gas pipeline network.
This flexibility makes it suitable for mining areas, smelters, new industrial estates, power plants in remote areas, and other locations with limited access to gas infrastructure.
Helping to Reduce Logistics Operational Costs
The larger storage capacity of LNG allows for lower distribution frequency, which means the need for a delivery fleet can also be reduced. This has the potential to improve transportation and storage cost efficiency in large-scale operations.
However, the magnitude of savings still depends on consumption volume, distribution distance, and the infrastructure used.
More Reliable Energy Supply to Maintain Production Continuity
Industries require a stable energy supply so that production processes can run without disruption.
LNG enables the storage of large energy reserves on site, so the risk of production disruptions due to supply limitations can be minimized. This adds value for industries that operate continuously 24 hours a day.
Better Suited for Large-Scale Energy Needs
LNG is more suitable for industries with high energy needs, such as mining, smelting, power generation, manufacturing, cement, and petrochemicals.
Compared to CNG, LNG’s storage capacity and distribution system better supports the need for large volume and continuous energy supply.

What Are the Positive Impacts of LNG Use for the Industrial Sector?
The use of LNG can improve operational efficiency by reducing fuel delivery frequency and refilling needs, making logistics activities more efficient compared to using CNG for large-scale energy needs.
In addition, a more reliable LNG supply helps maintain production continuity, reduces the risk of downtime, and gives companies the flexibility to build facilities in areas not yet reached by the gas pipeline network.
With these various benefits, LNG serves not only as an energy source, but also as part of a company’s strategy to improve operational efficiency, maintain business sustainability, and support energy transition targets.
For these benefits to be obtained optimally, LNG solutions need to be designed in accordance with the characteristics and needs of each industry.
To address this need, PGN LNG Indonesia provides LNG solutions ranging from procurement to supporting infrastructure, helping companies develop more reliable and efficient energy solutions that are aligned with efforts to transition toward lower-emission energy.
