the countries and different industries are looking for new systems with less
resource consumption, high energy-conversion efficiency and low emission.
For example:
Department of Energy (DOE) of United States has put forward the
Vision 21 energy system [1] (Fig. 1). Its idea is to get syngas through coal
gasification. The syngas could be used to produce hydrogen as the fuel
for fuel-cell automobiles in one way. In another way, the syngas could
be used in the hybrid cycle of high temperature SOFC and gas turbine to
produce electricity. Its efficiency could reach 50. . . 60%, pollutant emission
could be negligible and economic features could be 10 percent better than
conventional pulverized coal boiler power plant.
Shell Company has put forward the concept of Syngas Park. In this
park, coal or residual oil is gasified. The produced syngas can be used to
produce electricity with IGCC, to produce methanol and fertilizer in “once
through” way and can also be used as town gas supply [2] (Fig. 2).
