What are the Different Types of Gas the Fuel a Gas Generator?

We are known to supply PowerLink generators for our customers, but we are often asked what kind of gas powers these generators. In this article, we will discuss the different types of gas that are used to fuel these generators, as well as which gas generators they are used by.

Natural Gas

Natural gas is a naturally occurring mixture of gaseous hydrocarbons, primarily methane gas, and is classified as a fossil fuel and non-renewable energy source that is formed when microorganisms decompose under anaerobic conditions, and because of this, the gas is extracted from the ground. Because of the ease of extracting natural gas from the ground, it is unsurprising that it has multiple applications and has been utilised by many industries as an energy source.

For the range of PowerLink generators we sell, natural gas is used in both the range of gas generators and cogeneration units that are made, thanks to the versatility of natural gas, which has resulted in the natural gas units we sell being by far the most popular gas power product.


Biogas is an environmentally friendly renewable energy source that is produced by the breakdown of waste material such as leftover food and animal waste. Biogas is created when microorganisms break the waste material down, otherwise known as anaerobic digestion, but this breakdown of materials must take place in an enclosed environment which usually means that biogas is utilised on farms or other properties that have a large space of land to accommodate a biogas building.

When using biogas as a fuel for generators, biogas is used in both the range of gas generators and cogeneration units that we supply to our customers, and is available to be used in open sets, canopy sets and containerised sets, making it an extremely versatile form of fuel for generators.

Liquified Petroleum Gas (LPG)

Liquified Petroleum gas, or LPG, is a hydrocarbon gas that exists in a liquid form and is a low-carbon, highly efficient, colourless fuel. LPG gas is available in two different variations, Butane and Propane, with the PowerLink units we use utilising the propane variant meaning that our generators can be used outside when housed in a canopy generator design, or alternatively, placed in an outbuilding, as propane has a -42OC boiling point.

The LPG gas is used to fuel PowerLink gas generators, specifically the GRS series which can provide a power rating of 12KVA – 220KVA and come fitted with a double bunded fuel tank, a PowerLink engine and an alternator and is housed in a modular and compacted canopy design.
