**Challenge:**So far hydrogen production is too expensive. Currently the market is served by 96% grey hydrogen (meaning H2 created by natural gas or methane, without capturing greenhouse gases) which is responsible for 830M Tonnes of CO2 emissions. Blue hydrogen is no alternative since it is basically the same as grey hydrogen, just with carbon capturing. In reality CO2 capture is very expensive and has the added problem of methane leakage along the supply chain.Green hydrogen, meaning hydrogen produced by renewable energy sources, is currently prized at around 5US$/kg. This prize needs to come down to a third in order to make it an effective energy source. At Electrogenos we aim to make green hydrogen the most viable and competitive technology. We are taking a top-down approach to achieve that goal with < 1.5$/Kg by 2025\. Because we are dealing with a very competitive market our technology is set for rapid commercialization.This project aligns perfectly with the UK's 'Net Zero' strategy of 5GW of low carbon hydrogen capacity by 2030\. It would also boost the UK's position as hydrogen producing nation.**Innovation:**In this project we will develop a novel surface enhancement technique for the electrodes of our 4kW electrolyser prototype. The enhanced electrodes will boost efficiency and durability of the hydrolyser cell. This will provide a higher output of hydrogen while saving costs. It will improve the integral part of our product, the electrolyser cell itself.This project has the benefit of coupling disruptive manufacturing tools (soft tools) with a novel design that can outperform what is now available on the market (being made of precious metals or achieved through expensive manufacturing techniques).Our chief scientist is specialized in developing microstructures via electroplating for the heat-exchanger market which has very tight profit margins and keeping costs to a minimum through scalable continuous manufacturing is a must. During his PhD thesis he developed many electrocatalysts for hydrogen production processes. Both experiences led to the next logical step in founding Electrogenos Ltd with its unique approach to develop novel electrolyser cells. This grant funded project would offer us the opportunity to further our technology and speed up commercialization.

**挑战：**到目前为止，氢气生产成本太高。目前，市场上 96% 的灰氢（指由天然气或甲烷产生的 H2，不捕获温室气体）提供服务，其二氧化碳排放量为 8.3 亿吨。蓝氢是别无选择的，因为它与灰氢基本相同，只是具有碳捕获功能。事实上，二氧化碳捕获非常昂贵，而且还存在供应链中甲烷泄漏的问题。绿色氢，即由可再生能源生产的氢，目前的价格约为 5 美元/公斤。为了使其成为有效的能源，这个奖项需要降低到三分之一。在 Electrogenos，我们的目标是使绿色氢成为最可行和最具竞争力的技术。我们正在采取自上而下的方法，以到 2025 年实现< 1.5 美元/公斤的目标。因为我们面对的是一个竞争非常激烈的市场，所以我们的技术将快速商业化。该项目完全符合英国到 2030 年实现 5GW 低碳氢产能的“净零”战略。它还将提升英国作为制氢国的地位。**创新：**在这个项目中，我们将为 4kW 电解槽原型的电极开发一种新颖的表面增强技术。增强型电极将提高水解槽的效率和耐用性。这将提供更高的氢气产量，同时节省成本。它将改进我们产品的组成部分，即电解槽本身。该项目的优点是将颠覆性制造工具（软工具）与新颖的设计相结合，其性能优于目前市场上现有的工具（由贵金属或贵金属制成）通过昂贵的制造技术实现）。我们的首席科学家专门通过电镀为热交换器市场开发微结构，该市场的利润率非常紧张，并且必须通过可扩展的连续制造将成本降至最低。在他的博士论文期间，他开发了许多用于氢气生产过程的电催化剂。这两段经历催生了下一个合乎逻辑的步骤，即成立 Electrogenos Ltd，并以其独特的方法开发新型电解槽电池。该赠款资助的项目将为我们提供进一步发展我们的技术并加速商业化的机会。
