Equinor’s gas operations
Equinor is the largest gas producer on the Norwegian continental shelf, and the second-largest gas supplier in Europe. The combined gas volumes from Equinor and SDFI (the Norwegian state’s gas volumes) constitute more than 20 per cent of the gas market in Europe.
What is natural gas?
When people talk about natural gas, you may hear them use a number of terms that refer to different types of gas, such as dry gas, wet gas and LNG.
Natural gas is an umbrella term for a type of gas that has formed through the decomposition and transformation of organic matter below the surface of the earth. The gas may be composed of a number of chemical substances with different characteristics. Most of the substances are composed of hydrogen and carbon atoms and we therefore call them hydrocarbons.
Dry gas is gas that at regular pressure and temperature does not contain any liquid components. It consists mainly of methane, but also often consists of some ethane and smaller amounts of heavier hydrocarbons and CO2. Such gas is also called pipeline gas and is transported in pipelines to the customers.
Wet gas contains both dry gas and heavier hydrocarbon compounds in a liquid phase. In addition to ethane, this means propane, butane and the heavier hydrocarbons. Under normal pressure and temperature, the wet gas will be partly liquid, partly gas. To get dry gas, the liquid phase is separated and split, and sold as pure components (ethane, propane, butane, etc.).
LNG is an abbreviation of liquefied natural gas, i.e. natural gas that has been liquefied by cooling it down. LNG maintains a very low temperature (-162 degrees C) and is transported in special LNG carrier ships to the customers.
Why should we use natural gas?
Gas production and storage
Natural gas transportation pipeline systems
Natural gas from the Norwegian continental shelf runs through an extensive network of pipelines. It is the largest in the world of its kind, extending over 8,000 kilometres.
The pipelines connect the fields at sea and the processing plants onshore in Norway to landing points in Germany, Belgium, France and Great Britain.
Equinor is technical service provider for the operator and responsible for the technical operation for most of these pipelines.
Owner: the Gassled partnership
Technical service provider: Equinor
Gas storage: Equinor has two gas storage facilities: Etzel in Germany and Aldbrough in Great Britain.
Natural gas from a climate perspective
Did you know that Europe can cut CO2 emissions significantly by replacing coal with natural gas in electricity production? The UN Intergovernmental Panel on Climate Change (IPCC) states that using in the energy sector is an important measure in reducing global CO2 emissions.
Crossing the Arctic Circle with Polarled
The 480-kilometre Polarled pipeline conveys gas from the Aasta Hansteen field in the Norwegian Sea to the gas plant at Nyhamna.
