Summary
An oxygen-blown KRW integrated gasification combined-cycle plant producing hydrogen, electricity, and supercritical-CO₂, was studied in a full-energy cycle analysis extending from the cord mine to the final destination of the gaseous product streams. A location in the mid-western US was chosen 160-km from Old Ben No.26 mine which ships 3,866 tonnes/day of Illinois No.6 coal by diesel locomotive. Three parallel gasifier trains, each capable of providing 42% of the plant's 413.5 MW nominal capacity use a combined total of 3,488 tonnes/day of 1/4 inch prepared coal. The plant produces a net 52 MW of power and 3.71 x 10⁶ nm³/day of 99.999% purity hydrogen which is sent 100 km by pipeline at 34 bars. The plant also produces 3.18 x 10⁶ nm³3/day of supercritical CO₂ at 143 bars, which is sequestered in enhanced oil recovery operations 500 km away. A CO₂ emission rate of 1 kgCO₂/kWh was assumed for power purchases outside the fence of the IGCC plant.
