项目摘要

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.

建立氢作为燃料的生成和使用的技术已建立，但是目前，储存氢的最佳方法是将气体加压到350 bar或更高（即350倍大气压力）。这具有成本和安全性。处理高压氢需要厚的重金属圆柱或笨重的复合缸。由可再生能源或网格的电力驱动的电气器很容易产生氢，但这是低压力的。因此，需要机械气体压缩机将气体压缩到350 bar以上。这种机械压缩机很昂贵，需要维护，在高压下存储大量氢需要爆炸区。能够利用金属氢化物（MH）固态存储在低压下存储大多数气体，不仅更安全，而且所需的体积要少得多。燃料电池（将氢和氧气转化为水和电力）也在这些低压下运行，因此对于某些固定应用，通过低压MH存储将氢存储是有道理的。该项目将建立一个原型，以证明技术的可行性并探索MH商店的市场潜力。本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资助的研究进行了开发和测试，并且与我们的最新热量管理建模相结合，将提供下一代金属储备，并降低了工厂的成本和更高的工厂成本，并降低了工厂的成本和更高的效率。这些商店将基于具有被动内部热管理设计的轻质铝压力容器。这将提供一个原型“ Off架子”氢存储，该原型可以在几个钢筋的压力下存储等效的气体质量到350杆压力缸，以用于固定应用，但体积较小。金属氢化物具有超过2 wt％的工作能力在1到30 bar之间的工作能力，非常适合从电解器中存储气体并将其输送到燃料电池。这是AB5的工作能力的两倍，而AB5的30％的工作能力是AB2 Hydrides的工作能力，但原材料成本低于任何一种竞争对手合金。
