Abstract

This article discusses the definition of “clean” hydrogen produced by various pathways with a focus on transitioning from color-coded definitions to one that is based on the emissions generated in its creation. Herein, we also discuss the limitations of color-coding by providing a refined critique and assessment. With increasing emphasis on decarbonization efforts and clean energy transition, clean hydrogen’s role has been recognized more than ever, from clean energy bills and roadmaps to net-zero scenarios, which necessitates a clear, unambiguous definition for clean hydrogen. This article aims to help stimulate discussions as some colors’ associations may fade in favor of carbon intensity of the hydrogen production, in light of recent developments and interests in re-categorizing hydrogen production pathways and reducing associated carbon intensity from a life-cycle perspective.

(重新)定义清洁氢:从颜色到排放
本文讨论了各种途径产生的“清洁”氢的定义,重点是从颜色编码的定义过渡到基于其创建过程中产生的排放的定义。在这里,我们还通过提供一个精细的批评和评估来讨论颜色编码的局限性。随着对脱碳努力和清洁能源转型的日益重视,从清洁能源法案和路线图到净零情景,清洁氢的作用比以往任何时候都得到了更多的认可,这就需要对清洁氢有一个清晰、明确的定义。鉴于最近的发展和对氢生产途径的重新分类以及从生命周期的角度降低相关碳强度的兴趣,本文旨在帮助激发讨论,因为一些颜色的关联可能会褪色,有利于氢生产的碳强度。
