Abstract

Low-carbon hydrogen can play a significant role in decarbonizing the world. Hydrogen is currently mainly produced from fossil sources, requiring additional CO2 capture to decarbonize, which energy intense and costly. In a recent Green Energy & Environment paper, Cheng and Di et al. proposed a novel integration process referred to as SECLRHC to generate high-purity H2 by in-situ separation of H2 and CO without using any additional separation unit. Theoretically, the proposed process can essentially achieve the separation of C and H in gaseous fuel via a reconfigured reaction process, and thus attaining high-purity hydrogen of ∼99%, as well as good carbon and hydrogen utilization rates and economic feasibility. It displays an optimistic prospect that industrial decarbonization is not necessarily expensive, as long as a suitable CCS measure can be integrated into the industrial manufacturing process.

工艺重组和强化:实现高效碳捕获和低成本蓝氢生产的新兴机遇
低碳氢可以在世界脱碳方面发挥重要作用。氢气目前主要由化石来源生产,需要额外的二氧化碳捕获才能脱碳,这是一项能源密集且成本高昂的工作。在最近的绿色能源&;环境文件,Cheng和Di等人。提出了一种称为SECLRHC的新型集成工艺,通过原位分离H2和CO而不使用任何额外的分离单元来产生高纯度H2。理论上,所提出的方法基本上可以通过重新配置的反应过程实现气体燃料中C和H的分离,从而获得~99%的高纯度氢气,以及良好的碳和氢利用率和经济可行性。它显示了一个乐观的前景,即只要能够将合适的CCS措施融入工业制造过程,工业脱碳就不一定昂贵。

期刊介绍: Green Energy & Environment (GEE) is an internationally recognized journal that undergoes a rigorous peer-review process. It focuses on interdisciplinary research related to green energy and the environment, covering a wide range of topics including biofuel and bioenergy, energy storage and networks, catalysis for sustainable processes, and materials for energy and the environment. GEE has a broad scope and encourages the submission of original and innovative research in both fundamental and engineering fields. Additionally, GEE serves as a platform for discussions, summaries, reviews, and previews of the impact of green energy on the eco-environment.
