Pipeline transport ethanol in Brazil, and there are several ethanol pipeline projects in Brazil and the United States. The main problems related to the transport of ethanol by pipeline are its corrosive nature and tendency to absorb water and impurities in pipelines, which are not problems with oil and natural gas.

The material to be transported is closely mixed with water before being introduced to the pipeline; at the far end, the material must be dried. One example
Central Europe Pipeline System European countries, known as the Northern European Pipeline System (NEPS).
