Where it comes from…
Natural gas is a fossil fuel
Natural gas is found after marine life has died
and been put under great pressure and turns to
Amount of potential energy stored in a fuel per unit
Higher the energy density, the more energy may be
stored or transported for the same amount of mass.
Natural Gas has an energy density of 39 MJ/m^3
Natural Gas has a higher energy density than things like
black coal, which allows it to go farther and be more
Liquefied Natural Gas (LNG) is the gas compressed into
a liquid form so it can be transported easier and
consumes less volume.
Low density of gas makes it more expensive to transport
A section of pipe in oil service can hold 15 times more
energy than when used to transport high pressure gas.
Gas pipelines must be larger in diameter, and pipelines
can’t always be used because of location between
producers and consumers.
Transported by ship, barge, truck, rail, and pipeline.
Proportions of World Use
North America is one of the leading consumer of Natural Gas-
-- the U.S. consumes a significant amount more than it
Canada provides a lot of the natural gas for the U.S.
Mexico could become a significant source.
U.S. imports LNG from Algeria.
Other key producers/consumers:
France, Spain, Korea, Belgium, Italy, Taiwan, and Japan.
Natural Gas is said to be the most important energy source for the future.
Since there is an abundance and it’s better for the environment, the need for
natural gas for energy in the U.S. is predicted to keep growing.
Natural Gas is extremely efficient because it loses very little energy when
being put to use.
Cleanest burning fossil fuel, very few byproducts are emitted in to air as
Eliminates oil spills, soil contamination, and expensive environmental clean
Natural gas uses complex underground pipeline systems that are hard to
maintain– making it expensive.
They are very combustible and methane explosions are possible.
The extraction can be a disadvantage because the gas is creating pressure in
the ground, supporting the soil, then being extracted can create cavities–
which can cause the ground to sink.
Natural gas is very toxic when breathing it indoor.
