Pipelines have been used for transportation of ethanol in Brazil, and there are several ethanol pipeline projects in Brazil and the United States.
EA Energy assumed 48% of ethanol would be moved by pipeline.
Wider use of pipelines to transport ethanol is problematic for several reasons. It means addressing ethanol’s water affinity problem (ethanol is water soluble meaning it absorbs water). The second challenge to transporting ethanol by pipeline is the need to address corrosion issues. Ethanol-related corrosion problems can result from how ethanol behaves in the pipe.
