Abstract

Hydrogen has attracted widespread attention as a carbon-neutral energy source, but developing efficient and safe hydrogen storage technologies remains a huge challenge. Recently, liquid organic hydrogen carriers (LOHCs) technology has shown great potential for efficient and stable hydrogen storage and transport. This technology allows for safe and economical large-scale transoceanic transportation and long-cycle hydrogen storage. In particular, traditional organic hydrogen storage liquids are derived from nonrenewable fossil fuels through costly refining procedures, resulting in unavoidable environmental contamination. Biomass holds great promise for the preparation of LOHCs due to its unique carbon-balance properties and feasibility to manufacture aromatic and nitrogen-doped compounds. According to recent studies, almost 100% conversion and 92% yield of benzene could be obtained through advanced biomass conversion technologies, showing great potential in preparing biomass-based LOHCs. Overall, the present LOHCs systems and their unique applications are introduced in this review, and the technical paths are summarized. Furthermore, this paper provides an outlook on the future development of LOHCs technology, focusing on biomass-derived aromatic and N-doped compounds and their applications in hydrogen storage.

液态有机氢载体储氢：催化剂、可再生载体和技术——综述

氢作为一种碳中性能源受到了广泛关注，但开发高效、安全的储氢技术仍然是一个巨大的挑战。近年来，液态有机氢载体(lohc)技术在高效、稳定的储氢和输氢方面显示出巨大的潜力。该技术可实现安全、经济的大规模跨洋运输和长周期储氢。特别是，传统的有机储氢液体是通过昂贵的精炼程序从不可再生的化石燃料中提取的，导致不可避免的环境污染。生物质由于其独特的碳平衡特性和制备芳香族和氮掺杂化合物的可行性，在制备lohc方面具有很大的前景。根据最近的研究，通过先进的生物质转化技术，苯的转化率几乎可以达到100%，收率可以达到92%，在制备生物质基lohc方面显示出巨大的潜力。综述了现有的lohc系统及其独特的应用，并对其技术路径进行了总结。展望了lohc技术的未来发展，重点关注生物质衍生芳香族化合物和n掺杂化合物及其在储氢领域的应用。

期刊介绍： Carbon Resources Conversion (CRC) publishes fundamental studies and industrial developments regarding relevant technologies aiming for the clean, efficient, value-added, and low-carbon utilization of carbon-containing resources as fuel for energy and as feedstock for materials or chemicals from, for example, fossil fuels, biomass, syngas, CO2, hydrocarbons, and organic wastes via physical, thermal, chemical, biological, and other technical methods. CRC also publishes scientific and engineering studies on resource characterization and pretreatment, carbon material innovation and production, clean technologies related to carbon resource conversion and utilization, and various process-supporting technologies, including on-line or off-line measurement and monitoring, modeling, simulations focused on safe and efficient process operation and control, and process and equipment optimization.
