No.20 Introduction scenarios of low-grade coal for fuel to power generation in Japan:Consideration of Dewatering-in-Oil Process

Abstract

We analyzed the costs of lignite at power plants in Japan considering transportation costs and technical data of drying processes such as a dewatering-in-oil method that has dewatered lignite avoid spontaneous firing and transported to Japan. The analysis shows the costs of lignite dried on site in the export countries are cheaper at power plants in Japan than the costs of lignite dried in Japan and are competitive with bituminous coal. This is because the on-site drying can reduce contained water transportation and use low cost lignite before transportation for fuel to the drying process.
