Abstract
A method of making available economical fuels from arctic environments without melting the permafrost along a transportation right of way characterized by preparing a liquid fuel having a viscosity below 2 centipoises at 32.degree.F; cooling and transporting the cold liquid fuel, with or without the admixing of a solid fuel therewith to form a cold slurry, through a pipeline at a temperature below 32.degree.F through the frozen permafrost to a destination. The liquid fuel may be methanol synthesized from coal when the solid fuel is coal; or it may be a petroleum fraction where solid fuel deposits are adjacent an oil field or the like. Also disclosed are specific processes and systems for carrying out the invention.
