Although past growth in pipeline transport in the Western world has been slow and steady, inflation and the recent concern about energy supplies have caused a surge of interest in hydraulic transport, especially for coal. In the United States, the lack of Federal legislation for eminent domain has hampered progress, but 10 states now have such laws. Plans for three new overland coal slurry pipelines in the United States and Europe were announced, and a large pipeline in Brazil for phosphate is scheduled to begin operation in 1978. Two new research pipeline facilities in England and West Germany were commissioned in 1978, one research pipeline facility is under construction, and another is planned, in the United States. One full-scale hydraulic haulage system in an underground coal mine has begun operations in West Germany, and another is under construction in the United States. Three concepts for reducing or eliminating the problem of limited water supply received attention in 1978. Transporting coal in methanol is a new concept, and although coal in oil and in stabilized suspension are not new approaches, they are being considered.
