摘　　要：从能量利用角度考察了纯粹用氢作燃料的氢能经济的可行性 ,阐述了燃料电池车自身发展的困难和矛盾所在 ,详细地研究了我国二氧化碳的排放源并指出了最切实可行的减排切入点——发电行业 .通过从效率、经济性等角度对发电厂减排 CO2 的各种方案的对比 ,发现 IGCC在CO2 减排方面具有很大的优势 .最后从考察 IGCC的进一步发展方向出发 ,提出了能够真正实现零排放的能源系统和切实可行的减排 CO2This article firstly examines the feasibility of hydrogen economy from the viewpoint of energy utilization efficiency. Obstacles and contradictions to the development of fuel cell vehicles are then set forth. By studying sources of CO 2 emission in China, this article points out the most practical cutting in point for CO 2 mitigation power generation. Based on this, several cases of CO 2 capture from power plants are analyzed in efficiency and economic aspects. The comparison shows that IGCC has the great advantage over other candidates. Finally for further development of IGCC, this paper puts forward coal gasification based poly generation energy system with feasible CO 2 mitigation scenario.
