项目摘要

Decades of research have been devoted to storing hydrogen more economically and efficiently, and solid-state stores based on hydrides of metal alloys, such as intermetallics and high-entropy alloys, are one of the most extensively studied materials. A wide range of exciting potential applications are available, from hydrogen storage for transportation, stationary applications for refuelling and energy storage, to hydrogen compressors and thermal energy storage. Their practical applicability varies widely as a function of their thermodynamic properties which, when combined with other factors such as sustainability, cost, kinetics, capacity, has led to thousands of metal hydrides being investigated experimentally. Working together with an in-house modelling group, who will run computational high-throughput screening of materials databases and identify new candidate metal alloys with favourable properties for the aforementioned applications, this project aims to experimentally synthesize novel metal alloys shortlisted by computational screening, and characterise their structures and hydrogen absorption/desorption properties. This project forms part of our ongoing collaboration with Sandia National Laboratories on a joint experimental/computational project to identify new metal alloys for hydrogen storage and related applications. The project will also expose the candidate to LCM Ltd a leading manufacturer and supplier of complex metal alloys.

数十年来的研究致力于更经济、更有效地储存氢气，基于金属合金氢化物（例如金属间化合物和高熵合金）的固态储存是研究最广泛的材料之一。有一系列令人兴奋的潜在应用，从用于运输的氢存储、用于加油和能量存储的固定应用，到氢压缩机和热能存储。它们的实际适用性因其热力学性质而变化很大，当与可持续性、成本、动力学、容量等其他因素相结合时，已经导致数千种金属氢化物正在接受实验研究。该项目与内部建模小组合作，对材料数据库进行计算高通量筛选，并确定具有上述应用有利性能的新候选金属合金，该项目旨在实验合成通过计算筛选入围的新型金属合金，并表征其结构和吸氢/解吸性能。该项目是我们与桑迪亚国家实验室正在进行的联合实验/计算项目合作的一部分，该项目旨在确定用于储氢和相关应用的新型金属合金。该项目还将向 LCM Ltd（一家领先的复杂金属合金制造商和供应商）展示候选人。
