With increasing CO2 emissions and concerns over mass use of fossil fuels, the use of renewable sources of energy and carbon-free fuels is of critical importance for a transition to net-zero emissions and hydrogen represents a real alternative to fossil fuels.Hydrogen is notoriously difficult to store as conventional storage methods require extreme conditions such as high pressures or low temperatures. At H2GO Power we have developed a solid-state hydrogen storage system that represents a safer, cheaper, and denser alternative to conventional storage technologies and exploits the reversible chemical bond that H2 can form with other molecules, allowing absorption and desorption cycles to be carried out several thousands of times.The materials we use in our patented technology, however, require a period of activation which represents a bottleneck step in terms of time and overall cost. Understanding the factors affecting activation times will allow targeted engineering of materials, leading to a decreased consumption of hydrogen and overall a more efficient, cheaper, and denser product.Using the National Physical Laboratory (NPL) state of the art facilities we are planning to carry out a detailed investigation on the particle morphology and crystallographic properties of our storage material that, coupled with a study of hydrogen preferential paths within different particles, will provide invaluable information on the step to adopt to optimise the activation time of our materials.We will be using a variety of Scanning Electron Microscopy (SEM), Energy Dispersive X-ray Spectroscopy (EDS), and X-Ray Photoemission Spectroscopy (XPS) to image the surface and particle morphology at high resolution and provide information on variations in elemental composition. X-ray Diffraction (XRD) while Electron Backscattered Diffraction (EBSD) will also be used for the analysis of the phases and crystallographic structures and orientation on the samples.Nanoscale secondary ion mass spectrometry (NanoSIMS) is one of the rare techniques that can map the distribution of hydrogen and do so at 100 nm spatial resolution. It will be used to examine the association of hydrogen with microstructural features such as individual particles and the grain boundaries between them. It can also help determine if other trace and light elements are present in the sample that is unmeasurable or below the detection limits of the other techniques.There are few laboratories globally that have these capabilities and expertise all under one roof, and thus NPL is well-positioned to undertake these measurement challenges.

随着二氧化碳排放量的增加以及对化石燃料大量使用的担忧，使用可再生能源和无碳燃料对于向净零排放过渡至关重要，而氢气代表了化石燃料的真实的替代品。众所周知，氢气难以储存，因为传统储存方法需要极端条件，如高压或低温。在H2GO Power，我们开发了一种固态储氢系统，该系统代表了传统储氢技术的更安全，更便宜，更密集的替代品，并利用H2与其他分子形成的可逆化学键，允许进行数千次吸收和解吸循环。然而，我们在专利技术中使用的材料，需要一段时间的激活，这在时间和总成本方面是瓶颈步骤。了解影响活化时间的因素将有助于有针对性地设计材料，从而减少氢的消耗，并总体上提高产品的效率、成本和密度。我们计划利用国家物理实验室（NPL）最先进的设施，对我们的存储材料的颗粒形态和晶体学特性进行详细研究，再加上对不同颗粒内氢优先路径的研究，将为优化我们材料的活化时间提供宝贵的信息。我们将使用各种扫描电子显微镜（SEM），能量色散X射线光谱（EDS），和X射线光电子能谱（XPS），以高分辨率对表面和颗粒形态进行成像，并提供有关元素组成变化的信息。X射线衍射（XRD）和电子背散射衍射（EBSD）也将用于分析样品的相和晶体结构和取向。纳米二次离子质谱（NanoSIMS）是一种罕见的技术，可以绘制氢的分布，并在100 nm的空间分辨率。它将被用来检查氢与微观结构特征，如单个颗粒和它们之间的晶界的关联。它还可以帮助确定样品中是否存在无法测量或低于其他技术检测限的其他痕量和轻元素。全球很少有实验室拥有这些能力和专业知识，因此NPL处于有利地位，可以应对这些测量挑战。
