The E-Gas™ coal gasifier is a pressurized, upflow, entrained slagging design with a unique two-stage operation. Like the GE gasifier, E-Gas™ is a slurry-feed gasifier. Wet crushers produce slurries from the raw feed coal. Coal slurry concentrations typically range from 50 to 70% depending on the inherent moisture and quality of the feed coal.

The term 'clean coal' is increasingly being used for supercritical coal-fired plants without CCS, on the basis that CO 2 emissions are less than for older plants, but are still much greater than for nuclear or renewables. Some 26% of primary energy needs are met by coal and 37% of electricity is generated from coal, compared with 23% for
