An unceasing growth of gas consumption in domestic households, industry, and power plants has
gradually turned natural gas into a major source of energy. Main drivers in this development are the
technical and economic advantages of natural gas. It is a clean, versatile, and easily controllable fuel. On
this basis, natural gas is often considered the form of energy that will be the ‘‘bridging fuel’’ to a
sustainable energy system, sometime after 2050. Unlike other main sources of energy, such as oil and
coal, gas is not traded on an actual world market. This paper provides an overview on demand and
supplies of natural gas (LNG) in the past as a function of gas prices, gas technology (gas sweetening,
liquefaction, shipping and re-gasification), and gas market and how they have changed recently. It also
discusses the likely developments in global LNG demand for the period to the year 2030.
