Natural gas generators – a sustainable alternative
A Natural gas generator is a type of generator that requires gas (propane or methane, for example), instead of traditional fuels like diesel or petrol. While natural gas generator engines are 80% similar to diesel generators, the key difference is that natural gas generator engines require spark plugs to ignite the fuel as gas does not ignite with compression. In addition to this, the diesel engine has a four valve cylinder head while the natural gas generator engine makes use of a 2-cylinder valve head, which enables optimum positioning of the spark plug. Natural gas generators are clean, quiet and powerful, allowing many benefits to the user.
Natural gas generators are suitable for a wide variety of applications:
- Natural gas prime (continuous) generators
- Natural gas backup generators
- Low-emission power generation
Why choose natural gas generators?
Natural gas generators have several unique advantages, including:
One considerable benefit of natural gas generators is the cost of natural gas vs. diesel, especially when considering longer running periods and power outages.
Natural gas generator engines burn cleaner and produce less pollutants, with 50 and 60% lower CO2 emissions than their diesel counterparts.
“Compared to Engines fuelled with conventional diesel/gasoline, natural gas vehicles (NG) can yield significantly lesser amounts of harmful emissions such as nitrogen oxides, particulate matter, and toxic and carcinogenic pollutants as well as the greenhouse gas carbon dioxide.” – US Department of Energy.
Natural gas generators can operate from main gas lines, eliminating the need for fuel storage. This makes them ideal for installation in areas where fuel storage, space or accessibility may be a challenge.
While liquid fuel generators require on-site fuel storage and maintenance, natural gas generator engines are fuelled through gas lines, eliminating the need for costly and time-consuming fuel maintenance tasks.
