LNG,a highly transportable fossil fuel,is gaining popularity as an alternative to petroleum products and coal.Per MW of power,electricity generated from natural gas yields less than half the carbon dioxide(CO,)emissions than coal-fired power generation.Alongside a reduction in other pollutants such as sulfur dioxide(SOx)and soot,these are some of the reasons that many countries are increasing their usage of revaporized LNG for power generation.Germany and Poland have traditionally used hard coal and lignite as major energy sources.Both countries have built,and are planning more,LNG import terminals.The introduction of LNG as a fuel for buses and shipping is based on the similar logic that,despite LNG not being carbon-neutral,it is less harmful than gasoline or diesel.On the other hand,natural gas is a very potent greenhouse gas.One tonne of methane released into the atmosphere has the same impact on global warming as 28 tonnes of CO,.Gas leaks during the extraction,liquefaction,and distribution of LNG must therefore be eliminated.
