Gas: The Cleanest Fossil Fuel

Liquefied Natural Gas (1/14)

A view of Hammerfest, the Arctic boom town. The whole town was lit up by a giant 100-meter-high (320 feet) flame erupting from a flare tower at the Snoehvit complex.

Snoehvit, a facility where natural gas is converted to liquid form for easier transportation or storage, is the first facility in the Arctic and Europe to export liquefied natural gas (LNG). LNG produces less pollution than other fossil fuels when being burned. However, the energy needed to transport it at more than 160 degrees Celsius and convert it back to a usable makes LNG a major source of greenhouse gases. (Photo: Reuters)
