To alleviate the pressing problem of greenhouse gas emissions, the development and deployment of sustainable energy technologies is necessary. One potentially viable approach for replacing fossil fuels is the development of a H2 economy. Not only can H2 be used to produce heat and electricity, it is also utilised in ammonia synthesis and hydrocracking. H2 is traditionally generated from thermochemical processes such as steam reforming of hydrocarbons and the water-gas-shift (WGS) reaction. However, these processes suffer from low H2 yields owing to their reversible nature. Removing H2 with membranes and/or extracting CO2 with solid sorbents in situ can overcome these issues by shifting the component equilibrium towards enhanced H2 production via Le Chatelier's principle. This can potentially result in reduced energy consumption, smaller reactor sizes and, therefore, lower capital costs. In light of this, a significant amount of work has been conducted over the past few decades to refine these processes through the development of novel materials and complex models. Here, we critically review the most recent developments in these studies, identify possible research gaps, and offer recommendations for future research.

通过热化学过程提高制氢量
为了缓解紧迫的温室气体排放问题,必须开发和部署可持续能源技术。一种潜在的可行的替代化石燃料的方法是发展H 2经济。H 2不仅可以用于产生热量和电能,还可以用于氨合成和加氢裂化。传统上,H 2是从热化学过程生成的,例如碳氢化合物的蒸汽重整和水煤气变换(WGS)反应。但是,这些过程由于其可逆性而遭受H 2收率低的困扰。用膜去除H 2和/或用固体吸附剂原位萃取CO 2通过Le Chatelier原理,可以通过将组分平衡转移到提高H 2产生的方法来克服这些问题。这有可能导致能源消耗减少,反应堆尺寸减小,从而降低资金成本。有鉴于此,在过去的几十年中,通过开发新颖的材料和复杂的模型进行了大量的工作来完善这些过程。在这里,我们批判性地回顾了这些研究的最新进展,确定了可能的研究差距,并为以后的研究提供了建议。
