Which should I use? Natural gas vs diesel generator efficiency

Choose the right generator for your on-site power needs. Here’s a breakdown of the advantages and disadvantages of diesel generators compared to gas generators.

Industrial generators can be noisy during operation, which is why they often come either containerized or with a canopy. But what’s the difference between these types, and why are they necessary? Generators are essential for many applications in noise-sensitive locations like rooftops or basements. Open-set generators, or those that are neither containerized or coupled with a canopy, can cause significant disruption to nearby residents and construction teams. So, which type of noise-reducing solution is best for you? Compare the choices below.

Canopy generators

• Noise Level: A canopy can help reduce the noise output of an industrial generator significantly.
• Weather Protection: A canopy provides protection from the potential of wind or rain causing damages to the system.

Containerized generators

• Noise Level: Offers an even greater reduction in noise output than a canopy.
• Flexibility: Can be a great solution for sites that feature roof-top space for the generator’s placement.
• Maintenance Reduction: Requires less routine checks due to the secure container keeping the generator in a safe, clean environment.
• Affordability: Often the cheaper, more flexible solution due to ease of deployment and connection.

What are the main applications for the types of generators used in industry?

Standby power

• Diesel: Typically the type of fuel needed for standby power generators.
• Adaptable: Standby power generators can automatically provide power for a vast array of time periods; whether for a few short seconds or hours.
• Emergency Response: Ideal for outages due to power outages, weather emergencies, and more.
• Other Power Source: Standby generators require power from mains in order to operate.

Prime power

• Flexibility: Prime power generators can be diesel or gas powered.
• Remote Sites: This is where most prime power generators are used due to no power supply available onsite.
• Impactful Use: Prime power generators are ideal for bringing power back to remote locations, communities, and other larger industrial needs.
• More Maintenance: Prime power generators do need more regular maintenance depending on the run time and operating conditions.
• Reliability: These generators tend to have an unlimited run time, making them a perfect solution for large applications.

Diesel vs. Natural Gas Generators: Key Differences and Use Cases

The two most common generator types on the market are diesel engine powered generators and those using gas powered engines.

Apart from the fuel powering them, they have other distinctive qualities which make them more or less adequate according to the use we want to give them.

Let’s see what they are.

Note: In this article, “gas” refers to natural gas or liquefied petroleum gas (LPG), not gasoline (petrol). These are commonly used in gas-powered generators, not to be confused with petrol-fueled engines.

Diesel generators

The reliability of a classic

For quite a long time, diesel engine generators have been a standard in the market. Their good reputation was the result of a great flexibility of application, both in industrial and household areas, as well as their robustness and reliability.

This type of generator may be used as a main power supply, as well as for co-generation or emergency applications. They are fully autonomous and may, therefore, function in places which have absolutely no power-supplying networks.

What advantages have made diesel generators so popular?

• They are more easily disassembled and installed than gas units, making their installation wherever needed a simpler task, while also using a fuel which is easily accessible and more economical than gasoline.
• They are robust and sustainable, capable of ensuring many hours of yearly operation.

• Diesel fuel gives high efficiency to the equipment using it because it burns at a much higher temperature than gasoline.
• Diesel fuel is also very safe because it is less flammable than other types of fuel.

The main disadvantage of this type of generator, as in the case of any machinery which includes a diesel engine, is that it causes high levels of polluting gas emissions. Therefore, the present day diesel generators incorporate an additional antiparticle filtration system that ensures its conformity with the legislation in force.

Natural gas powered generators

Clean and economical energy

Gas engine generators have gained much popularity due to their great reliability, cost efficiency and sustainability.

This type of generator can be used as a primary power source, in co-generation applications or as an emergency source and its engine may be fuelled by liquefied natural gas (LNG) or liquefied petroleum gas (LPG). The latter is a gaseous fuel obtained from the distillation of oil.

Generators powered by LNG fuelled engines get their fuel from the natural gas distribution network, whereas LPG fuelled generators are connected to a tank which will have to be periodically refuelled.

What are the benefits of natural gas powered generators?

• They are more respectful of the environment, because the gas causes less emission than other non-renewable fuels (such as coal, diesel or gasoline).
• They are economical, because gas is the most affordable fuel, second only to coal (which is not an option due to its high emission level).
• They are high-efficiency generators in co-generation applications.

• When fuelled by an underground natural gas network, the fuel supply is not conditioned by inclement weather or problems with the communication infrastructure (which do condition diesel generators that need periodic refuelling).
• They are highly compatible and easy-to-use units, given that it is possible to install them in remote locations, using high capacity tanks.
• They are very quiet generators.

Among the disadvantages of this type of generator, one must consider the following:

• Liquefied natural gas (LNG) powered generators are less autonomous than diesel engine ones because it is absolutely necessary to connect them to a distribution network.
• In the case of LNG equipment connected to the network, one has to take into account that any catastrophe or natural disaster can affect the supply system.
• Gas is an exceptionally flammable fuel and entails a bigger fire hazard than diesel.

• The engine and control system are much more demanding, which can result in the product’s final price being higher.
• They require a more punctual and complex maintenance.

Diesel vs Gas Generators: Which One Should You Choose?

Deciding between a diesel or gas-powered generator requires careful consideration of various factors. Each type has its own set of advantages and disadvantages that make them suitable for different applications and environments. Here are the key factors to consider:

1. Application and Usage

• Primary Power Source: If you need a generator for continuous operation, such as in remote locations without a power grid, diesel generators are often preferred due to their robustness and fuel efficiency.
• Emergency Backup: Both diesel and gas generators can serve as reliable backup power sources. However, gas generators, especially those connected to a natural gas line, can provide uninterrupted fuel supply during emergencies without the need for refueling.

2. Environmental Impact

• Emissions: Gas generators produce fewer emissions compared to diesel generators, making them a more environmentally friendly option. This can be a critical factor if you are concerned about meeting stringent environmental regulations or minimizing your carbon footprint.
• Noise Levels: Gas generators are generally quieter than diesel generators, which can be important in residential areas or locations where noise pollution is a concern.

3. Fuel Availability and Cost

• Fuel Costs: Diesel fuel is typically more expensive than natural gas, but it provides higher energy efficiency, which can offset the cost over time.
• Fuel Supply: Gas generators connected to a natural gas line have a continuous fuel supply, whereas diesel generators require regular refueling. However, in areas without natural gas infrastructure, diesel may be the more practical choice.

4. Maintenance and Longevity

• Maintenance Requirements: Diesel generators are known for their durability and lower maintenance needs. Gas generators, while efficient, often require more frequent and complex maintenance due to the nature of the fuel and engine.
• Lifespan: Diesel generators tend to have a longer operational lifespan, making them a more cost-effective option in the long run for high-demand applications.

5. Safety Considerations

• Flammability: Natural gas is highly flammable, posing a greater fire hazard compared to diesel. Diesel fuel, being less volatile, is considered safer to store and handle.
• Reliability: In situations where natural disasters might disrupt gas supply lines, diesel generators offer greater reliability as they can operate independently of external fuel supply networks.

What About Gasoline Generators?

In some markets, especially in North America, “gas-powered generator” often refers to gasoline-fueled engines. While these are common for small portable generators, this article focuses on natural gas and LPG-powered equipment, typically used in industrial and backup applications.
