An Australian team including CSIRO (Melbourne; www.csiro.au) and the Uni- versity of Newcastle (www.newcastle.edu.au) has developed an alternative pathway for producing ultra-low-ash coal that, the team believes, can be used to fuel diesel engines, thus providing the opportunity for diesel engines to replace steam engines for large-scale base-load power generation. The method involves slurrying and...
