Underground Gas Storage

The average European country's storage capacity is of the order of 20% of annual demand compared to the UK's total of less that 5%. By 2010 it is predicted that up to 40% of UK gas supply could be imported and by 2015, up to 80%.  This is due to a decline in indigenous gas supplies, principally from the North Sea, coupled with an increase in demand.

In order to ensure future security of gas supply, in terms of availability and reliability, a diversity of supply sources and UK entry points, together with the ability to store large quantities of gas are essential.   

Costain Energy & Process, a leading international gas handling and treatment contractor, has a wide experience of gas storage projects in depleted fields and salt strata, working with a number of European utility majors, including E.ON, GDFSUEZ and WINGAS. Costain is also able to draw on many years of project execution capability in undertaking projects of this nature.
