History •Early 20th Century •WWII •1980’s

1980’s While abandoned, lots of wildlife moved in, for example: • Water voles • Lizards • Grass snakes • Adders

Recent Development •Around 2001/2002 it became an LNG Storage Plant. •LNG - Liquefied Natural Gas •Due to predicted exhaustion of North Sea supplies

Current Processes •Ships •System •On-site

Ships

River Thames North Sea

Medway Estuary

System •Piped off ships in liquid form and then stored in tanks. •To connect to national supply, the gas must be vaporised. •Pipes are run through a water bath and the vapours are collected.

Current Development •Power Station agreement •New storage tanks •New Jetty •New Substation •New Nitrogen Generation Plant

New Storage Tanks •Three in the process of being built •One new tank = 4 old tanks •Volume = 190,000 litres •Each New tank ≈ Royal Albert Hall

Current Development •Power Station agreement •New storage tanks •New Jetty •New Nitrogen Generation Plant •New Substation

Conclusion The gas in the North Sea will soon reach a point where it is no longer cost effective. This means that gas will need to be shipped in from other countries. The storage of this gas is a complex process involving many different sectors.
