Abstract
A system and a method for producing hydrogen and electrical power from an aqueous ammonia solution are provided. An exemplary system includes a distillation unit to produce ammonia gas from the aqueous ammonia solution, a compression unit to boost the pressure of the ammonia gas, a membrane separator to catalytically convert the ammonia gas to nitrogen and hydrogen and remove the hydrogen as a permeate, and a micro turbine to combust a retentate to generate energy.
Claims10

- distilling the aqueous ammonia solution to produce ammonia gas and a waste stream;
- compressing the ammonia gas;
- converting the ammonia gas to nitrogen and the hydrogen;
- separating the hydrogen in a membrane separator as a permeate;
- and
- combusting a retentate in a micro turbine to generate the electrical power.
