Natural gas is a naturally occurring mixture of gaseous hydrocarbons consisting primarily of methane in addition to various smaller amounts of other higher alkanes. Low levels of trace gases like carbon dioxide, nitrogen, hydrogen sulfide, and helium are also usually present. Natural gas is colorless and odorless, so odorizers such as mercaptan are commonly added to natural gas supplies for safety so that leaks can be readily detected.

The hydrogen economy uses hydrogen to decarbonize economic sectors which are hard to electrify, essentially, the "hard-to-abate" sectors such as cement, steel, long-haul transport, etc. In order to phase out fossil fuels and limit climate change, hydrogen can be created from water using renewable sources such as wind and solar, and its combustion only releases water vapor into the atmosphere.

Energy in Victoria, Australia is generated using a number of fuels or technologies, including coal, natural gas and renewable energy sources. Brown coal, historically, was the main primary energy source for the generation of electricity in the state, accounting for about 85% of electricity generation in 2008. The amount of coal-fired power has decreased significantly with the closure in 2017 of the Hazelwood power station which supplied around 20% of Victoria's electricity, and to a lesser extent with the exit of Anglesea power station in 2015. Brown coal is one of the largest contributors to Australia's total domestic greenhouse gas emissions and a source of controversy for the country. Australia is one of the highest polluters of greenhouse gas per capita in the world.
