 In light of the dwindling supplies of North Sea gas, Milford Haven has become home to two new LNG terminals which eventually could provide 25% of the UK's gas requirement.Under construction from 2006, South Hook is based on the former Esso refinery facility, while Dragon LNG is based on a brownfield site of the Gulf oil refinery, now also housing SEMLogistics chemicals.The regasified natural gas is fed through National Grid plc's South Wales Gas Pipeline to the distribution point at Tirley, Gloucestershire.
