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. Insufficient volumes and cost-effectiveness are other considerations limiting construction of ethanol pipelines. Slurry pipelines are sometimes used to transport coal or ore from mines. 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
Northern Lights (pipeline) by the Vukhtyl gas field, but later the pipeline was extended in order to connect with the Urengoy gas field. The Northern Lights pipeline system has a total length of , of which around is used to transport Russian gas to Europe. The pipeline runs from the Urengoy gas field through Vuktyl, Ukhta, Gryazovets, Torzhok and Smolensk to Minsk in Belarus and from there to Poland, Ukraine and Lithuania. A part of the newer Yamal–Europe pipeline runs parallel to the Northern Lights pipeline. A branch line from Gryazovets through Saint Petersburg to Vyborg supplies the Saint Petersburg area and Finland.
