Over the past 50–60 years, a dense pipeline network has been built up in Europe. This European interconnected system expands from the North Sea and the Baltic to the Mediterranean, and from West Siberia to the Atlantic. New projects are under construction with more kilometres of pipeline, with the aim of bringing more gas to Europe from Siberia, the Middle East and the Caspian Sea.
Natural gas is also brought to the European market by cargo ships, as liquefied natural gas (LNG), from the producing countries all around the world. This flexible form of transportation is taking on an increasingly important role for Europe and new terminals are under construction to accommodate more ships.
