Shell has just announced it is to build the world's first floating liquefied natural gas facility (FLNG) 200km off North-West Australia's coast. As well as that mammoth project, the energy giant is also heavily involved with the huge gas potential in Qatar with the Pearl Gas to Liquids (GTL) project - the world's largest GTL plant. Shell downstream director Mark Williams outlined some of his alternative fuels and transport thinking at the recent Challenge Bibendum sustainable mobility event in Berlin.
