Diesel engines have long been the generator industry’s workhorse. They are rugged, reliable, and efficient. On the other hand, natural gas generators have become increasingly popular due to their lower emissions and fuel costs.
So, which one is better? We dive into some of the key benefits of each to help you chose which generator is best for your needs.
What Are The Key Differences Between Diesel and Natural Gas Generators?
When deciding which generator is best for your needs, you should consider several key differences between diesel and natural gas generators.
Diesel generators are typically more expensive than natural gas generators but are also more efficient and have a longer lifespan. However, natural gas generators are less expensive to operate but may not be as durable as diesel generators.
But let’s break it down:
Efficiency
Diesel generators are typically 20-40% more efficient than natural gas generators. This is because diesel engines can produce more power with less fuel than natural gas engines.
This means that diesel generators will typically use less fuel than natural gas generators, making them more cost-effective in the long run. In addition, diesel engines can run at a higher capacity for more extended periods without needing to be refueled, making them ideal for continuous operation.
Lifespan
Diesel generators can last up to twice as long as natural gas generators. That is because diesel engines are built to tolerate the high temperatures and pressures associated with prolonged use.
Also, diesel fuel is less likely to deteriorate and clog up the engine than natural gas.
Price
Diesel generators typically cost more upfront than natural gas generators. However, they usually have lower operating costs due to their higher efficiency. On the other hand, natural gas generators are less expensive, but they typically require more maintenance than diesel generators.
Since diesel generators can last up to twice as long as natural gas generators and maintenance costs are lower, diesel generators are a more cost-effective option in the long run.
Maintenance
Natural gas generators typically require more maintenance than diesel generators. This is because natural gas is a more volatile fuel and can clog up the engine if it is not maintained correctly. Therefore, it’s essential to regularly check the fuel filter and spark plugs on a natural gas generator.
Diesel generators also require regular maintenance to keep them running smoothly. That can include changing the oil, checking the coolant levels, and ensuring the air filter is clean.
However, for both types, it is critical to have them serviced regularly by a qualified technician to ensure that they are operating well and that any potential problems are identified early.
Emissions
But both diesel and natural gas generators emit pollutants when burned, including sulfur dioxide, nitrogen oxide, and mercury. However, natural gas emits lower levels of these pollutants than diesel fuel.
Natural gas generators produce about 30% less carbon dioxide, nitrogen oxide, particulate matter, and other dangerous exhausts released into the atmosphere than diesel generators.
As a result, natural gas generators are more environmentally friendly than diesel generators. Business owners who are conscious of their environmental impact will likely prefer natural gas.
Comparing Diesel vs. Natural Gas Generators
If you want an efficient and long-lasting generator, a diesel generator is probably the best option. However, a natural gas generator may be a better choice if you are on a more conservative budget.
So, ultimately, deciding which type of generator to buy should be based on your specific needs and requirements.
