SINGLE will enable ammonia as an energy carrier in the hydrogen value chain through demonstration of a proton ceramic electrochemical reactor (PCER) that integrates the ammonia dehydrogenation (ADH) reaction, hydrogen separation, heat management and compression in a single stage. The realization of 4 process steps in a single reactor allows the technology to achieve unprecedented energy efficiencies and directly deliver high purity pressurized hydrogen. SINGLE will demonstrate the technology at a 10 kg H₂ /day scale that will provide a pathway for future scale-up systems ranging from small (fuelling stations) to large centralized (at harbour) deployments. The achievements in SINGLE will be an important proof of technological feasibility advancing the technology from TRL3 to TRL5. The consortium counts on partners from the industry, institute and academia sector with high world-wide excellence in the respective fields of catalysis, electrochemical membrane reactors, life-cycle assessment, process engineering, control systems and hydrogen fuelling stations.
