Thin films CF04
Project costs: 1.934 T€
Project period: 06/2020–08/2022
Integrating new electroceramic thin films into energy systems enables the small-scale implementation of resource-efficient direct and flexible energy conversion processes for ammonia synthesis. In joint project CF04, partners are developing high-performance thin-film-based membrane electrode units (MEA) for the decentralised synthesis of ammonia through the process of solid-state ammonia synthesis (SSAS). SSAS is an electrochemical production method (power-to-ammonia) that is suitable for flexible and decentralised process management, feed-in of fluctuating renewable energy into the grid and grid-independent operation on a small scale. This new process allows for a highly efficient direct synthesis of ammonia from atmospheric nitrogen and water and plays an important role in improving the lifetime and synthesis rates for ammonia. It is important to the minimise power losses associated with the bulk resistance in thick electrolyte membranes and poorly performing catalysts. The development of pressure-resistant tubular MEAs for SSAS is a critical step in achieving CAMPFIRE’s broader goal to develop cost-effective processes for the production of green ammonia and realise our vision – ‘wind and water to ammonia’. The joint project will produce a ceramic-supported and metal-supported SSAS-MEA with first performance data for the production of ammonia, as well as assessments of the long-term stability of the components under the conditions of ammonia synthesis on a laboratory scale.
