Ammonia-to-Power“ - Energy Recovery from ammonium-containing Substances by means of Vacuum-Membrane Distillation and Ammonia-Fuel Cell
A considerable high amount of ammonium (in the form of Nitrogen salts) is available in various waste product streams such as industrial wastewater, municipal sewage or digestate. Due to lack of efficient resource recovery technologies, the ammonium bound hydrogen in waste products cannot be utilized. Both these problems - the efficient recovery of ammonia gas and the utilization and energy recovery of ammonia in a fuel cell - require the development of new appropriate technologies. Within the project "Ammonia-to-power" a vacuum membrane distillation method (MD) for ammonia gas extraction and an ammonia fuel cell (SOFC ammonia) are developed.
The outcome of the project will be an optimized membrane distillation plant at laboratory scale with a characterized vacuum membrane module and appropriate process parameters, as well as a 5kW SOFC CHP system exclusively operating with ammonia. Furthermore a technical concept for a real-scale plant will be elaborated.
