Helping to achieve a cleaner tomorrow
Natural gas is already the cleanest hydrocarbons that we have on our planet. When used in power plants, it emits around half the CO2 of coal-fired power plants. Shell is a pioneer of technology to cool natural gas, dramatically reducing its volume for much easier transportation.
In November 2013, Wired covered a story on LNG with Shell scientists to understand exactly what it is. As Wired.co.uk reports, liquefied natural gas, or LNG, is simply natural gas super-cooled to 162°C, which shrinks its volume 600 times until it becomes a liquid. By shrinking the volume of the gas, it is easier to store and ship to other parts of the world.
Floating liquefied natural gas, or FNLG, is the production of LNG at sea using giant floating facilities longer than four football pitches laid end-to-end. Shell is building its first floating facility, Prelude FLNG, to extract and process the LNG at source, 200 kilometres off the coast of Australia.
When you consider that a gas-fired power plant takes much less time to start and stop than a coal-fired plant, natural gas becomes a good partner to renewable energy sources such as solar and wind, which may only generate energy when the sun shines and the wind blows.
