用于产生和使用氢作为燃料的技术已经建立，然而目前储存氢的最佳方式是将气体加压到350巴或更高（即，350倍大气压）。这有成本和安全方面的考虑。处理高压氢气需要厚而重的金属气瓶或笨重的复合气瓶。由可再生能源或电网的电力驱动的电解槽可以很容易地产生氢气，但这是在低压下。因此，需要机械气体压缩机将气体压缩到350巴以上。这种机械压缩机昂贵且需要维护，在高压下储存大量氢气需要鼓风区。利用金属氢化物（MH）固态存储器能够在低压下存储大部分气体不仅更安全，而且需要更少的体积。燃料电池（将氢和氧转化为水和电）也在这些低压下运行，因此对于某些固定应用，通过低压MH存储来存储氢是有意义的。该项目将建立一个原型，以证明该技术的可行性，并探索MH存储的市场潜力。该项目将使用一种创新的金属氢化物，该金属氢化物已通过EPSRC资助的研究开发和测试，结合我们最新的热管理模型，将提供下一代金属氢化物存储，降低材料成本，降低工厂平衡的复杂性和更高的效率。这些悬挂物将基于一个轻型铝制压力容器，具有被动内部热管理设计。这将提供一个原型的“现成”氢存储，可以在几巴的压力下存储相当于350巴压力气缸的气体，用于固定应用，但体积较小。金属氢化物具有超过2wt%的工作容量，工作压力在1至30 bar之间，非常适合储存来自电解槽的气体并输送到燃料电池。这是一个工作能力的两倍，AB5和30%的市售AB2铝合金，但在较低的原材料成本比任何竞争对手的合金。

The technology for the generation and use of hydrogen as a fuel is established however at present the best way to store the hydrogen is to pressurise the gas to 350 bar or higher (i.e. 350 times atmospheric pressure). This has cost and safetyconsiderations. Handling high pressure hydrogen requires thick and heavy metal cylinders or bulky composite cylinders. Electrolysers driven by electricity from renewables or from the grid can readily generate hydrogen but this is at lowpressures. Thus mechanical gas compressors are needed to compress the gas to above 350 bar. Such mechanical compressors are expensive and require maintenance, the storing of large quantities of hydrogen at high pressure requires blast zones. Being able to store the majority of gas at low pressure utilising metal hydride (MH) solid state stores is not only safer but it requires much less volume. Fuel cells (which convert hydrogen and oxygen to water and electricity) operate at these low pressures too, so for certain stationary applications, storing hydrogen by a low pressure MH store makes sense. This project will build a prototype to prove the viability of the technology and explore the market potential for MH stores.This project will use an innovative metal hydride that has been developed and tested via EPSRC funded research and this combined with our latest heat management modelling will deliver the next generation metal hydride stores with reducedmaterials cost, reduced complexity of balance of plant and higher efficiency. These stores will be based on a lightweight aluminium pressure vessel with a passive internal thermal management design. This will deliver a prototype "off the shelf" hydrogen store that can store at a pressure of a few bar the equivalent mass of gas to a 350 bar pressure cylinder for stationary applications yet in a smaller volumetric footprint. The metal hydride has over 2 wt% working capacity operating between 1 and 30 bar, ideal for storing gas from electrolysers and delivering to fuel cells. This is a working capacity double that of AB5 and 30% that of commercially available AB2 hydrides, but at lower raw material cost than either competitor alloy.
