Liquefied natural gas (LNG) is an energy solution that can reach areas without gas pipelines. For safe and efficient transportation, LNG ISO Tanks are used, specialized containers designed to maintain stable LNG in cryogenic conditions.
This innovation is key to equitable energy distribution and strengthens the global energy supply chain. Let’s explore how LNG ISO Tanks are unlocking broader access to clean energy.
What Is an LNG ISO Tank?
The LNG ISO Tank is an international standard container specifically designed to transport LNG at cryogenic temperatures of around –162°C.
- Structure: Similar to a regular container, but with double, vacuum-insulated walls, like a giant thermos.
- Size: Available in 20–40-foot modules.
- Capacity: 20,000–40,000 liters, sufficient to supply energy for everything from small industries to mini-power plants.
- Material: Made of cryogenic steel, it is resistant to extreme temperatures, ensuring its safety.
With its modular design, the ISO Tank can be transported by truck, ship, or train, making LNG distribution more flexible.

How Do LNG ISO Tanks Differ from Other LNG Tanks?
LNG ISO tanks differ from large LNG infrastructure, such as onshore terminals or FSRUs.
- Scale: Large terminals handle millions of tons of LNG per year, while ISO tanks handle only thousands to hundreds of thousands of tons, suitable for small to medium-sized applications.
- Mobility: ISO tanks are portable, able to be transferred from ships to trucks or trains without complex loading and unloading infrastructure.

The Key Role of LNG ISO Tanks in Energy Distribution
Despite their smaller size, LNG ISO Tanks play a vital role in energy distribution. Here are some of their most important functions:
Serving Regions Without Pipeline Infrastructure
ISO Tanks facilitate the direct supply of LNG to consumers in areas without pipelines, such as remote or inland industrial areas.

Flexible Multi-Modal Distribution
The ISO Tank’s standard design allows for rapid transfer from ship to truck to train. This flexibility allows LNG to reach remote areas through a more efficient supply chain.
Cost-Effective for Small and Medium-Scale Needs
For SMEs, building an LNG terminal is clearly too expensive. With ISO tanks, LNG can be purchased as needed, simply supported by a small regasification unit.

Supporting LNG Use in Industry and Transportation
- Industry: Diesel-powered factories can switch to LNG for cost-effectiveness and lower emissions.
- Transportation: ISO Tank can supply LNG filling stations for trucks and ships.
Accelerating Access to Clean Energy Transition
LNG produces up to 50% lower CO₂ emissions than coal and is cleaner than diesel. ISO Tanks accelerate access to clean energy in off-grid areas, supporting global climate targets.
With its mobility, efficiency, and ability to reach areas without pipeline infrastructure, LNG ISO Tanks have proven to be a smart energy distribution solution. This technology not only addresses logistical challenges but also expands access to clean energy to support the transition to a low-emission future.
