Natural Gas Performance

High Performance + High Efficiency

Both natural gas and diesel engines and gen sets have proven performance and reliability. Diesel has a higher power density and can reach full load more quickly than natural gas; however, natural gas generators can meet the <:10 minimum start up time required for emergency power supply systems. Once started, reliability and performance of diesel, natural gas, and bi-fuel generators is equivalent. Diesel generators have a higher overall efficiency.

  • Natural gas, diesel, and bi-fuel generators have proven performance and reliability
  • Natural gas generators can meet the :10 start up time required for emergency power systems
  • The overall efficiency (HHV/kWe) of diesel generators is 15% - 25% higher than natural gas 

Total Cost of Ownership Calculator

Installed costs for backup power generation systems can vary significantly based on the application and site specific conditions. In addition, regional fuel prices for natural gas and diesel also are a key factor. Since there are no universal costs, use the TCO calculator to review total ownership costs based on your local rates and product requirements.

Environmental Responsibility: Smaller Carbon Footprint

Environmental Responsibility

Natural gas is one of the cleanest fossil fuels to use. Emissions of sulfur, nitrogen, and carbon dioxide (a greenhouse gas) are considerably lower compared to diesel fuel.

Diesel engines also emit more nitrogen oxide and particulate matter than similar spark-ignited units, which has led to increased scrutiny from the Environmental Protection Agency (EPA). Intense emission level regulations and aggressive tier changes from the EPA could eventually result in diesel engines being taxed at a greater rate due to their higher carbon dioxide emissions.

In addition, the high level of emissions produced by diesel gensets may increase the difficulty in procuring an air-quality permit. Obtaining an air-quality permit for natural gas units is easier because they produce fewer harmful emissions. For companies that emphasize a core value of “being green”, natural gas is the best fuel choice in most situations.
