氢能驱动下钢铁园区能源系统低碳发展模式

Low-carbon Development Mode for Energy System of Iron and Steel Park Driven by Hydrogen Energy

随着“碳达峰、碳中和”目标的提出及碳市场体系逐步完备,工业企业面临低碳转型和可持续发展的巨大压力,新能源大力发展及氢能在运输工具和工业生产中的应用为此提供了较好的机遇。基于此,利用新能源和氢能产业链重塑工业能源体系是促进工业发展的关键手段。以低碳、绿色、环保、节能为主要考量,构建“绿电-氢能-工业”耦合复杂系统,从能源流和碳流2个角度对比分析耦合系统具有的优势;通过构建环保、节能和经济性评价模型,定量说明耦合系统建设的可行性;通过分析中国钢铁工业发展现状,按不同发展速度测算钢铁工业绿色发展潜力。结果表明,钢铁工业绿色发展将极大地促进绿色氢气的发展与应用,氢能产业链的逐步成熟也将加快钢铁工业绿色转型速度,二者相辅相成。

With the introduction of the objective of“carbon emission peak and carbon neutrality”and the gradual completion of the carbon market system, industrial enterprises are facing tremendous pressure in the low-carbon transition and sustainable development. The vigorous development of renewable energy and the application of hydrogen energy in the transportation and industrial production have provided better opportunities for the industrial enterprises. Based on this, the use of renewable energy and hydrogen energy industry chains to reshape the industrial energy system is a major means to promote industrial development.By taking the low carbon, green, environmental protection, and energy saving as the main considerations, a coupling complex system consisting of“green power, hydrogen energy and industry”is built, and the advantages of the coupling system are compared and analyzed from two perspectives of energy flow and carbon flow. Through the construction of environmental protection, energy saving and economic evaluation models, the feasibility of the construction of the coupling system is quantitatively explained. By analyzing the development status of iron and steel industry in China, the green development potential of iron and steel industry is calculated according to different development speeds. The results show that the green development of iron and steel industry will greatly promote the development and application of the green hydrogen, the gradual maturity of the hydrogen energy industry chain will also speed up the green transformation of iron and steel industry,and they complement each other.
