氢基绿色能源全生命周期综合评价体系的标准化构建与应用研究OACHSSCD

Against the backdrop of global efforts to address climate change and accelerate the low-carbon transformation of the energy system,hydrogen-based energy,as a key carrier for achieving deep decarbonization in high-energy-consuming sectors such as industry and transportation,occupies an increasingly prominent strategic status.However,the hydrogen energy industry chain is long and the technical paths are diverse.There is an urgent need for a standardized,scientific,rigorous,transparent and internationally aligned evaluation system to conduct quantitative assessment and authoritative certification.Based on this,this paper systematically constructs a comprehensive evaluation system for hydrogen-based energy that takes life cycle assessment(LCA)as the core framework and deeply integrates the concepts and methods of standardization.The standardization system provides core standardization methodologies and tool support for the green value assessment of hydrogen-based energy projects,carbon emission rights trading,green financial support,and precise government policy implementation.This effectively guides the industry to avoid the"pseudo-green"trap and promotes the high-quality,sustainable and reliable development of the hydrogen energy industry.
