摘要

绿色氢基能源产品的定义差异是国际标准协同推进与碳排放核算准确性的关键挑战。为系统探究定义差异对碳排放核算的影响,基于生产工艺与碳排放双重视角,对绿氢、绿氨、绿甲醇在不同国家及国际组织中的定义范围、核算边界与技术标准展开全面对比分析。研究结果表明,各国在工艺路线认可度、排放阈值设定及系统边界划分上存在显著分歧,直接导致同一产品的碳排放核算结果偏差较大,进而引发国际贸易壁垒与绿色认证互认障碍。基于此,提出了符合我国国情的绿色氢基能源定义框架与标准化建议,为推动碳排放核算的一致性和国际协作提供支撑。

Abstract

The definition differences of green hydrogen-based energy products are a key challenge for the advancement of international standardization and the improvement of carbon emission accounting accuracy. To systematically explore the specific impact of these definition differences on carbon emission accounting, a comprehensive comparative analysis was conducted on the definition scope, accounting boundaries, and technical standards of green hydrogen, green ammonia, and green methanol in different countries and international organizations from the dual perspectives of production processes and carbon emissions. The results show that there are significant differences among countries in the recognition of process routes, the setting of emission thresholds, and the division of system boundaries, which directly lead to significant deviations in the carbon emission accounting results of the same product, and further trigger trade barriers and obstacles to mutual recognition of green certifications in international trade. Based on this, a definition framework and standardization suggestions for green hydrogen-based energy products in line with China's national conditions are proposed to provide support for promoting the consistency of carbon emission accounting and international collaboration.
