GE will supply Chevron with equipment to fulfill Gorgon’s LNG production and CO2 sequestration.
According to the Energy Information Administration, between now and 2030 global energy consumption is projected to increase by 44 % with oil and gas, along with coal, continuing to meet the largest part of that demand.
The demand for natural gas – the cleanest burning fossil fuel, which plays a vital role in balancing economic growth and environmental responsibilities – is expected to grow by more than 67 percent by 2030.
The Gorgon Project’s estimated economic life is at least 40 years from the time of start-up. In addition to natural gas supply for domestic Australian use, Gorgon is critical to meeting Asia’s growing need for cleaner energy. To date the Gorgon partners have signed sale and purchase agreements for LNG export into Japan and South Korea, the world’s two largest LNG import markets, as well as India and China.
Globally, the net impact of using Gorgon LNG will result in about 45 million tonnes less greenhouse gas emissions, when compared with coal. That’s equivalent to taking around two-thirds of all Australian vehicles off the road.
The Gorgon natural gas fields are located at Barrow Island, around 130km off Western Australia. Gas will be extracted and delivered via subsea and underground pipelines to gas treatment and liquefaction facilities on Barrow Island's south east coast.
Three, 5-MTPA GE Main Refrigerant Compression Trains, each comprising two GE Frame-7 Gas Turbines plus advanced technology liquefaction compressors, will be utilized for the production of liquefied natural gas by chilling to –160°C, ready for shipping, before re-gasification and pipeline transportation for use by domestic and industrial customers.
Prior to liquefactioncarbon dioxide will be stripped out and injected into the depleted natural gas wells 1,300-meters deep to ensure its safe storage and the reduction of emissions. Six surface operating, 15 MW electric-motor driven GE Compression Trains will be deployed.
The GE Main Refrigerant Compression Trains and the GE Compression Trains for CO2 sequestration will be manufactured and tested in Florence and Massa, Italy, then shipped in 2011 and 2012.
