The Covid-19 lockdown provided us an invaluable opportunity to gather much needed real data to strongly argue for switching to a carbon emission free energy vector (eg. hydrogen) at earliest. As the world is now gradually moving to the post-Covid 19 peak era, by switching to hydrogen and renewable based energy system, we will be able to maintain the CO2 emission levels at that of the Covid-19 lockdown period. In fact, hydrogen could play a major role in all major areas of our energy landscape: namely domestic, transport and industry. However, for this transition to take place hydrogen has to successfully compete with current energy systems based on oil and gas resources. The economic case for it rests on two preconditions that complement each other; the first is that hydrogen can be produced affordably using environmental-friendly methods, and the second is that hydrogen utilization technologies will gain a significant market share in competition with other alternatives. In addition, technological advances in distributed hydrogen production would eliminate the stringent requirements in storage and transportation of hydrogen. Thermochemical and electrolytic methods are leading the scaled hydrogen production today, however, the cost of production is still a major barrier which prevent its adaptation at scale. As far as affordable hydrogen production is concerned, alternative and flexible production methods such as methane cracking are rapidly picking up today. Methane cracking which converts methane to hydrogen and capture carbon as a solid product, is a potential bridge technology during the transition to a sustainable hydrogen economy since it produces hydrogen with zero emissions of carbon dioxide. The process is flexible enough to alter the conditions to obtain value-added solid carbon (eg. single, double and multi-walled CNT, highly porous carbon). These solid carbon products are highly sought in many technology areas such as energy storage, air and water purification, food and beverage. This project is designed to investigates systematic alteration of process conditions to obtain value-added solid carbon specifically for energy storage area whilst high yield of hydrogen is still maintained. By doing this we aim to obtain high value-added carbon products and high yield of hydrogen. The project team will work with the Cambridge based Zinergy UK to industrial bench marking the solid-carbon and evaluate its commercial potential. (Zinergy UK is working to deliver flexible energy storage solutions for a wide range of areas including healthcare, defence and smart and remote working areas). Initially this project will recreate the current state-of-art hydrogen conversion levels and then analyse the resulting solid-carbon by-product to understand the growth process and its dependence on thegrowth substrate/catalysts. EffecTech Group (a UK based gas specialist company) will provide methane for the project and gas handling training. Then, the individual process conditions will be studied (eg. temperature, catalyst formulation, methane flow rate) to obtain a series of solid-carbon products at high H2 generation yield. The carbon products will then be used in supercapacitor electrodes and evaluate the energy storage properties. Frequent sample exchange with Zinergy UK will ensure benchmarking and market value of solid carbon products that we will make.

新型冠状病毒封城为我们提供了一个宝贵的机会，收集急需的真实的数据，以有力地支持转向无碳排放的能源载体（例如，能源转换）。氢）最早。随着全球逐步迈向后COVID-19高峰期，透过改用氢及可再生能源系统，我们将能够将二氧化碳排放水平维持于COVID-19封城期间的水平。事实上，氢可以在我们能源格局的所有主要领域发挥重要作用：即国内，运输和工业。然而，要实现这一转变，氢必须成功地与目前基于石油和天然气资源的能源系统竞争。它的经济理由取决于两个相辅相成的先决条件;第一个是可以使用环境友好的方法生产氢，第二个是氢利用技术将在与其他替代品的竞争中获得重要的市场份额。此外，分布式制氢的技术进步将消除对氢储存和运输的严格要求。热化学法和电解法是目前规模化制氢的主要方法，然而，生产成本仍然是阻碍其规模化应用的主要障碍。就负担得起的氢气生产而言，替代和灵活的生产方法，如甲烷裂解，今天正在迅速崛起。甲烷裂解将甲烷转化为氢气并将碳捕获为固体产品，是向可持续氢经济过渡期间的潜在桥梁技术，因为它产生氢气，二氧化碳排放量为零。该工艺足够灵活，可以改变条件以获得增值的固体碳（例如，单壁、双壁和多壁CNT，高度多孔碳）。这些固体碳产品在能源储存、空气和水净化、食品和饮料等许多技术领域都受到高度追捧。该项目旨在研究系统地改变工艺条件，以获得专门用于储能领域的增值固体碳，同时仍然保持高氢气产量。通过这样做，我们的目标是获得高附加值的碳产品和高产率的氢。该项目团队将与总部位于剑桥的Zinergy UK合作，对固体碳进行工业基准测试，并评估其商业潜力。（Zinergy UK正致力于为医疗保健、国防、智能和远程工作领域等广泛领域提供灵活的储能解决方案）。最初，该项目将重建当前最先进的氢转化水平，然后分析产生的固体碳副产物，以了解生长过程及其对生长基质/催化剂的依赖性。英国的天然气专业公司ESTech Group将为该项目提供甲烷和天然气处理培训。然后，将研究各个工艺条件（例如：温度、催化剂配方、甲烷流速）以获得一系列具有高H2生成产率的固体碳产物。然后，碳产品将用于超级电容器电极，并评估储能性能。与Zinergy UK的频繁样品交换将确保我们将生产的固体碳产品的基准和市场价值。
