Module 1: Properties and Characteristics of Natural Gas

           Lesson 1.1: What is Natural Gas?

             Definition           Natural gas is a fossil fuel formed when layers of buried plants, gases, and animals are
                                  exposed to intense heat and pressure over thousands of years. The energy that the
                                  plants originally obtained from the sun is stored in the form of chemical bonds in natural
                                  gas.

             Sources              Natural gas is found in deep underground rock formations or associated with other
                                  hydrocarbon reservoirs like coal.

                                  Renewable Natural Gas (RNG)
                                  Another source of natural gas is Renewable Natural Gas, also referred to as RNG.
                                  RNG is created by capturing methane from existing organic waste – such as landfills,
                                  dairy farms, food waste or wastewater sludge – through anaerobic digestion.

                                  RNG can be used in the same applications as natural gas derived naturally from the
                                  earth.






























             Common Uses of       Natural gas is an energy source often used for heating, cooking, and electricity
             Natural Gas          generation. It is also used as fuel for vehicles and as a chemical feedstock in the
                                  manufacture of plastics and other commercially important organic chemicals.
