Advanced Metrology for Polymer Electrolysers - AMPERE

氢能将在清洁经济和实现雄心勃勃的气候目标方面发挥核心作用。然而，为了充分发挥其潜力，我们必须通过水电解实现低成本，广泛生产零碳H2，使用可再生能源供电。这一挑战的基础是在真实的世界操作条件下提高对这些从原子到细胞的复杂系统的理解。AMPERE汇集了来自学术界、国家实验室和工业界的专家，以诊断和了解电解槽中的降解和性能限制过程。最重要的是，该项目将解决系统动力学的影响，这是使用太阳能和风能等间歇性能源时运行的一个关键但经常被忽视的方面。我们将利用独特的最先进的测量技术工具箱，从聚合物膜中的离子运动到电极组件的局部电化学活动，水管理和气泡形成的长度尺度。这将产生多尺度电解槽动态的明确画面，我们对现实生产率和现场/操作方法的关注将确保这些见解具有实际意义。因此，AMPERE的产出将有助于大规模引入零碳氢气，作为清洁发电，供暖和运输的化学原料和能源载体。

Hydrogen will play a central role in the clean economy and in meeting ambitious climate targets. However, to realise its full potential, we must enable low cost, widespread production of zero-carbon H2 by water electrolysis, powered using renewable energy. Underlying this challenge is improved understanding of these complex systems from atoms to cells under real world operating conditions. AMPERE brings together experts from academia, national laboratories and industry to diagnose and understand degradation and performance-limiting processes in electrolysers. Crucially, this project will address the effects of system dynamics, a key but often overlooked aspect of operation when using intermittent energy sources such as solar and wind.We will leverage a unique toolbox of state-of-the-art measurement techniques, spanning length scales from ionic motion in the polymer membrane, to local electrochemical activity across electrode assemblies, water management and bubble formation. This will produce the definitive picture of multi-scale electrolyser dynamics and our focus on realistic production rates and in-situ/operando methods will ensure these insights will have practical relevance. Thus, the outputs of AMPERE will help usher in zero-carbon H2 at scale, as a chemical feedstock and energy vector for clean power generation, heating and transportation.
