Show applied directly to mobile combustors which are a major source of anthropogenic carbon dioxide emissions. In spite of this limited direct application, the potential impact of the proposed countermeasure is vast. Since about one-third of all fossil fuels are burned in large power stations, fitting the proposed system onto one-half of these plants would decrease the amount of carbon dioxide released into the atmosphere by about 15%. The pre-combustion removal concept may be employed to reduce indirectly carbon dioxide emissions from sources other than stationary combustion stations. Indeed, the reformer may be operated in a stand-alone mode to convert fossil fuels into relatively benign hydrogen mixtures or derivatives for off-plant use at a competitive cost (Mori, et al., 1991 b). An integrated hydrogen energy system centered on the pre-combustion carbon dioxide removal facility thus could facilitate the transition from fossil fuels to hydrogen energy under the umbrella of global warming mitigation.
