Consumption of ethane has grown every year since 2010 in the United States, and more ethane is now consumed in the country than either jet fuel or propane. Consumption of ethane, which we estimate using product supplied, grew by 50,000 barrels per day (b/d) in 2021, according to data from our March 2022 Petroleum Supply Monthly. We forecast in our March 2022 Short-Term Energy Outlook (STEO) that by 2023, U.S. consumption of ethane will grow by another 340,000 b/d.
