Elba Island is an island in the Savannah River, near the US port city of Savannah, Georgia, on the Atlantic Ocean. It functions as an import and export facility for liquefied natural gas. The island lies five miles downstream from the city of Savannah, and is part of Chatham County, Georgia. Its name comes from the Mediterranean island of Elba. In the early 1970s, the US energy company Sonat built an import and storage facility for liquefied natural gas on the island.
