AEIS's ability to provide storage for CO2 carbon capture, ethane, propane, butane, isobutane, and natural gasoline (pentanes plus).
NGL and CO2 Storage Opportunities
NGLs are hydrocarbons – in the same family of molecules as natural gas and crude oil, composed exclusively of carbon and hydrogen. Ethane, propane, butane, isobutane, and natural gasoline (pentanes plus) are all NGLs. Use of NGLs spans nearly all sectors of the economy. NGLs are used as inputs for petrochemical plants, burned for space heating and cooking, and blended into vehicle fuel. Significant volumes of NGLs are being produced in the Appalachian region. These resources are often shipped to other domestic markets for use or left unseparated in the natural gas stream, representing unrealized potential. Natural gas liquids are versatile products used in every end-use sector; residential, commercial, industrial (manufacturing and agriculture), transportation and electric power.
The natural gas produced in Appalachia contains valuable resources in the form of natural gas liquids (NGL), including ethane and propane. When separated from the natural gas stream, ethane and propane are key feedstocks for the petrochemical industry, used to produce compounds for making plastics and resins. Appalachian natural gas plant liquids production is projected to increase over 700 percent in the 10 years from 2013 to 2023.
Gas liquids are expensive to handle, store and transport compared to refined products. They require high pressure and/or low temperature to maintain liquid state for shipment and handling. NGL’s also require special trucks, ships, and storage (thick steel insulated tanks, or underground caverns for large volumes. The establishment of an Appalachian gas storage hub is likely to greatly decrease transport costs and increase profitability.
