Efficient Hydrogen and Ammonia Production via Process Intensification and Integration
The Colorado School of Mines will develop a more efficient method for both the conversion of hydrogen and nitrogen to ammonia and the generation of high purity hydrogen from ammonia for fuel cell fueling stations. Composed of 17.6% hydrogen by mass, ammonia also has potential as a hydrogen carrier and carbon-free fuel. The team will develop a new technology to generate fuel cell-quality hydrogen from ammonia using a membrane based reactor. In addition, similar catalytic membrane reactor technology will be developed for synthesis of ammonia from nitrogen and hydrogen at reduced pressure and temperature. This is aided by selective removal of ammonia, which enables equilibrium limitations to be surpassed, a fundamental constraint in conventional Haber-Bosch ammonia synthesis.
The proposed technology would serve as bridge to a renewable future, meeting demand while enabling major reductions in energy requirements and carbon footprint.
