Notably it also has low emissions of sulphur dioxide (SO 2), oxides of nitrogen (NOx) and particulate matter.

As a fuel, natural gas is set to become a significant source of power in the Flour Mills, Lagos, , 11 x JMS620 coming years. Natural gas is projected to become the most significant fossil energy medium in the next fifty years.

In countries where the national grid is unreliable and supplies of natural gas are abundant, gas engines provide an excellent source of reliable island mode power.

Understanding the methane number of the natural gas fuel is an important factor when determining the appropriate engine version to select.
