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.

生产和使用氢气作为燃料的技术已经确立，然而，目前储存氢气的最佳方法是将气体加压到350巴或更高(即350倍大气压)。这有成本和安全方面的考虑。处理高压氢需要厚重的金属钢瓶或笨重的复合材料钢瓶。由电力、可再生能源或电网驱动的电解器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。这种机械压缩机价格昂贵，需要维护，在高压下储存大量氢气需要爆炸区。能够利用金属氢化物(MH)固态存储在低压下存储大部分气体不仅更安全，而且需要的体积要小得多。燃料电池(将氢和氧气转化为水和电)也在这些低压下运行，因此对于某些固定应用，通过低压MH存储氢气是有意义的。这个项目将建立一个原型来证明技术的可行性，并探索MH存储的市场潜力。该项目将使用一种通过EPSRC资助的研究开发和测试的创新金属氢化物，这与我们最新的热管理模型相结合，将提供下一代金属氢化物存储，降低材料成本，降低设备平衡的复杂性和更高的效率。这些商店将基于具有被动式内部热管理设计的轻型铝制压力容器。这将提供一个现成的氢气存储原型，它可以在几巴的压力下将相当于质量的气体存储到350巴的压力气瓶中，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，工作在1到30巴之间，非常适合存储电解槽中的气体并将其输送到燃料电池。这是AB5氢化物的工作能力的两倍，是商用AB2氢化物的30%，但原材料成本低于竞争对手的任何一种合金。
