The growing environmental challenges have made decarbonisation a global priority. Renewable energy is key for decarbonisation, but their broad deployment requires **sufficient energy storage technologies** to balance the mismatch of intermittent renewable supply with electricity demand. Towards this goal, hydrogen has been rightfully acknowledged as a highly suitable renewable energy carrier.Hydrogen is **notoriously difficult to store**, as conventional storage methods require extreme conditions (e.g. high pressures or low temperatures). At H2GO we have **developed and deployed** a solid-state hydrogen storage technology that is a **safer, cheaper and denser alternative** to conventional storage technologies. Our technology exploits the reversible chemical bond that hydrogen forms with other molecules, allowing for storing and releasing hydrogen in cycles to be carried out **several thousand times**.However, while applying these cycles in our patented storage technology, we observed an **oxidation effect** when our storage materials are **exposed to oxygen and water molecules** (e.g. moisture present in air) which can affect their performance and lifetime. As we scale up production, our manual reactor filling process **needs to be upgraded to an automated process** while **mitigating any oxidation effects** during filling. Thus understanding the exact effects of oxidation and when they are most likely to occur will allow a targeted process for filling our reactors, in turn making our product more efficient and competitive.Using the National Physical Laboratory (NPL) state-of-art facilities and expertise in preparing reference gases, we will carry out **a detailed investigation of these oxidation effects** for our storage materials, providing valuable information on the most suitable automatic filling process to adopt.We will be using nano-SIMS (Secondary Ions Mass Spectrometry), to define the effects and extent of oxidation caused by a set of specially prepared reference gases. SIMS is **one of the rare techniques that can map the distribution of hydrogen and oxygen isotopes**, at 100 nm spatial resolution. We will use this method to **examine the relation of our hydrogen storage materials with oxygen and water molecules** together with the effects that they may bring to our materials.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.

日益增长的环境挑战使脱碳成为全球优先事项。可再生能源是脱碳的关键，但其广泛部署需要 ** 足够的储能技术 ** 来平衡间歇性可再生能源供应与电力需求的不匹配。为了实现这一目标，氢被认为是一种非常合适的可再生能源载体。众所周知，氢很难储存，因为传统的储存方法需要极端的条件（例如高压或低温）。在H2GO，我们开发并部署了一种固态储氢技术，这是传统储氢技术的一种更安全、更便宜、更密集的替代方案。我们的技术利用氢与其他分子形成的可逆化学键，允许在循环中存储和释放氢 ** 数千次 **。然而，在我们的专利存储技术中应用这些循环时，当我们的存储材料暴露在氧气和水分子中时，我们观察到了氧化效应。（例如，空气中存在的水分），这会影响它们的性能和寿命。随着我们扩大生产规模，我们的手动反应器灌装工艺 ** 需要升级为自动化工艺 **，同时 ** 减轻灌装过程中的任何氧化效应 **。因此，了解氧化的确切影响以及它们最有可能发生的时间，将有助于有针对性地填充我们的反应器，从而使我们的产品更有效，更有竞争力。利用国家物理实验室（NPL）最先进的设施和制备参比气体的专业知识，我们将对我们的存储材料进行这些氧化影响的详细调查 **，提供最合适的自动灌装工艺的有价值的信息。我们将使用纳米SIMS（二次离子质谱法）来确定一组特别制备的参考气体引起的氧化的影响和程度。西姆斯是 ** 能够以100 nm的空间分辨率绘制氢和氧同位素分布图 ** 的罕见技术之一。我们将使用这种方法来 ** 研究我们的储氢材料与氧气和水分子的关系 ** 以及它们可能给我们的材料带来的影响。全球 ** 只有 ** 少数实验室 ** 拥有这些能力和专业知识 **，因此NPL有能力承担这些测量挑战。
