This project is concerned with exciting developments of new electro-catalytic technologies for Green eNH3 production with the energy derived from wind power. This contrasts with the traditional catalytic process for industrial NH3 productionwhere non-renewable natural gas is used as the energy and H2 source with a concomitant release of large CO2 emission. Thus, the development of new renewable electrocatalytic technologies can substantially reduce carbon emission byutilizing wind energy to produce carbon free NH3. This electrification of the chemical industry will improve energy security by reducing the dependency on dwindling supply of natural gas. Further applications of eNH3 for energy storage and transportation will reduce the cost of integrating renewable into the energy mix. Oxford University and STFC will collaborate with Siemens, UK to explore various new catalytic surfaces to produce ammonia from nitrogen and hydrogen (or water) by electrochemical means. This program is part of a wider consortium which is making the UK a central research hub for Green Ammonia. Three different workstreams will be carried out as follows:Workstream 1. Management and Commercial Analysis (Lead partner Siemens). This portion of the project is focused on the management of the project and assessment of the commercial feasibility of the technology. Results from the 2 technical workstreams will be used to develop commercial models of the potential end systems.Workstream 2. Experimental analysis (Lead Partner Oxford University). This work is divided into 3 work packages each focusing on a different Nafion based system. Key figures of merit will be established i.e. NH3 reaction rate, faradaic efficiency, time stability, voltage characteristics.Workstream 3. Theoretical Analysis (Lead Partner Siemens). In conjunction with sub-contractors (OCF plc) and academic partner at STFC. This work stream is divided into 4 work packages. All results will be regularly exchanged with the other workstreams and will share 3 top level milestones. The work stream will be divided into 2 phases aligned with the work being undertaken in workstreams 1 and 2.

该项目涉及利用风能生产绿色eNH3的新电催化技术的令人兴奋的发展。这与传统的工业NH3生产催化工艺形成鲜明对比，其中不可再生的天然气被用作能源和H2来源，伴随着大量CO2排放的释放。因此，开发新的可再生电催化技术可以通过利用风能生产无碳NH3来大幅减少碳排放。化学工业的电气化将通过减少对日益减少的天然气供应的依赖来改善能源安全。eNH3在能源储存和运输方面的进一步应用将降低将可再生能源纳入能源组合的成本。牛津大学和STFC将与英国西门子公司合作，探索各种新的催化表面，通过电化学方法从氮气和氢气（或水）生产氨。该计划是一个更广泛的联盟的一部分，该联盟正在使英国成为绿色氨的中心研究中心。三个不同的工作流程将进行如下：工作流程1。管理和商业分析（主要合作伙伴西门子）。项目的这一部分侧重于项目管理和技术商业可行性评估。两个技术工作流的结果将用于开发潜在终端系统的商业模型。工作流2.实验分析（主要合作伙伴牛津大学）。这项工作分为3个工作包，每个工作包侧重于不同的基于Nafion的系统。将建立关键的品质因数，即NH3反应速率、法拉第效率、时间稳定性、电压特性。理论分析（主要合作伙伴西门子）。与分包商（OCF plc）和STFC的学术合作伙伴一起。该工作流程分为4个工作包。所有结果将定期与其他工作流交换，并将共享3个顶级里程碑。工作流程将分为2个阶段，与工作流程1和2中正在开展的工作保持一致。
