ExxonMobil Gas & Power Marketing is the world's largest non-government marketer of natural gas and has its office for Europe in Leatherhead.

ExxonMobil has supplied the UK market with gas for over 30 years. Sales in the UK represent around 12 per cent of the gas market in the UK, which is Europe's largest user of natural gas. Gas is sold to a range of customers including the power generation industry, and also gas distribution companies, who re-sell gas to customers in the industrial, commercial and domestic sectors.

European gas demand is expected to grow at about 1.5 per cent a year over the next 20 or so years, while regional production of natural gas is anticipated to begin declining in the next several years. This growing gap between demand and local production will result in a rapid increase in the need for imported gas supplies from new LNG and pipeline projects.

In the North Sea, the company is involved in multiple field developments, including the Ormen Lange and Statfjord Late Life projects.

ExxonMobil holds capacity in the new Langeled pipeline from Norway to the United Kingdom, and the company's joint venture in the Netherlands, Gas Terra, holds capacity in the BBL pipeline from the Netherlands to the UK. Both pipelines started commercial operations in 2006 and provide additional gas import capacity to the UK.

To meet the growing demand for LNG in the UK, ExxonMobil is involved in a joint venture with Qatar Petroleum to bring LNG from Qatar to the UK. The South Hook LNG regasification terminal, at Milford Haven in South Wales, is due to start up in 2008. When fully operational, it will have the capacity to meet around one fifth of Britain's gas needs.
