碳中和背景下的脱碳方案
摘要:随着“碳中和”目标的提出，我国的能源利用方式需面临调整。首先，介绍了目前我国非化石能源比重为15%左右，到2050年我国非化石能源比重将达到70%左右。其次，指出除了提高非化石能源的利用比例，在某些难以脱碳的领域必须利用碳捕集与利用等技术实现碳减排。接着，文章对碳捕集与利用技术做了详细介绍，碳捕集技术分别包括二氧化碳燃烧前捕集、二氧化碳燃烧中捕集和二氧化碳燃烧后捕集；二氧化碳利用技术主要包括物理应用、化工利用、生物质利用。由于新能源电解水制氢过程实现了完全脱碳，因此新能源电解水制氢被认为是脱碳的终极路线，在实现完全脱碳生产之前还要靠碳捕集技术来兜底。
Abstract：With the proposed goal of "carbon neutrality" , China's energy utilization mode needs to be adjusted. Firstly, it is introduced that the proportion of non-fossil energy in China is about 15% at present, and it will reach about 70% by 2050. Secondly, in addition to increasing the utilization proportion of non-fossil energy, carbon capture and utilization technology must be used to achieve carbon emission reduction in some difficult decarburization fields. Then, carbon capture and utilization technologies are introduced in detail. Carbon capture technologies include carbon dioxide capture before combustion, carbon dioxide capture during combustion and carbon dioxide capture after combustion. Carbon dioxide utilization technology mainly includes physical application, chemical utilization and biomass utilization. Due to the complete decarburization of hydrogen production by water electrolysis with new energy, hydrogen production by water electrolysis with new energy is considered to be the ultimate route of decarburization. Before the complete decarburization is realized, carbon capture technology is needed to cover the bottom.
