Choosing between a natural gas generator container and a diesel generator container is one of the most consequential decisions in remote site power planning. Get it right and you reduce fuel costs, emissions and logistics complexity. Get it wrong and you face supply chain problems, regulatory issues or a generator that can’t meet your load requirements. This guide compares the two technologies across the factors that matter most for industrial and remote site applications.
Natural Gas Generator Containers: Advantages and Limitations
Advantages
- Lower fuel cost — natural gas is typically 30–50% cheaper per kWh than diesel in markets with pipeline access
- Lower emissions — approximately 25–30% lower CO2 than diesel, and significantly lower NOx and particulate matter
- Continuous fuel supply — pipeline-connected units never run out of fuel, eliminating the logistics of diesel resupply
- Longer service intervals — gas engines typically require less frequent oil changes than diesel equivalents
- Quieter operation — gas engines generally produce less noise than comparable diesel units
Limitations
- Pipeline dependency — requires pipeline infrastructure or LNG/CNG supply chain at the site
- Higher installation cost — gas fuel systems require more complex installation than diesel tanks
- Cold start performance — gas engines can struggle in very cold climates without preheating systems
- Regulatory complexity — gas installations often require additional permits and inspections
Diesel Generator Containers: Advantages and Limitations
Advantages
- Fuel availability — diesel is available virtually everywhere, making it the default choice for truly remote locations
- No pipeline required — self-contained fuel tank integrated into the container
- Proven technology — diesel generators have decades of field-proven reliability in harsh environments
- Cold weather performance — diesel engines are more reliable in Arctic conditions with appropriate cold-start packages
- Lower capital cost — diesel units typically have lower purchase price than equivalent gas units
Limitations
- Higher fuel cost — diesel is more expensive per kWh than natural gas in most markets
- Fuel logistics — remote sites require regular diesel resupply, adding cost and operational complexity
- Higher emissions — diesel produces more CO2, NOx and particulate matter than natural gas
- Shorter service intervals — more frequent oil and filter changes increase maintenance cost
Bi-Fuel Systems: The Best of Both
For applications where gas supply is available but not guaranteed, bi-fuel generator containers offer a practical solution. These units run primarily on natural gas but automatically switch to diesel when gas supply is interrupted — providing the fuel cost and emissions benefits of gas with the reliability guarantee of diesel backup.
Bi-fuel systems are increasingly specified for:
- Offshore platforms with associated gas availability
- Industrial sites near gas infrastructure with unreliable supply
- Mission-critical applications requiring guaranteed uptime
- Sites transitioning from diesel to gas as infrastructure develops
Decision Framework: Which Technology Is Right for Your Project?
Choose Natural Gas If:
- Pipeline infrastructure exists or LNG/CNG supply is reliable
- The project duration justifies the higher installation cost
- Emissions reduction is a contractual or regulatory requirement
- Fuel logistics to a remote site are costly or operationally complex
- Ambient temperatures are above -20°C
Choose Diesel If:
- The site is genuinely remote with no gas infrastructure
- Project duration is short and capital cost must be minimised
- Arctic or sub-Arctic operating conditions apply
- Rapid deployment with minimal installation complexity is required
- Fuel storage on site is feasible and secure
Choose Bi-Fuel If:
- Gas supply is available but not guaranteed
- Maximum uptime is a critical requirement
- You want fuel flexibility without compromising reliability
Output Range and Container Sizing
| Application | Typical Output | Container Size |
|---|---|---|
| Small site / backup power | 20 – 100 kW | 10ft / 20ft |
| Medium industrial site | 100 – 500 kW | 20ft / 40ft |
| Large industrial / offshore | 500 kW – 2 MW | 40ft / custom |
