Abstract
The invention provides a method for the production of electrical energy from an ammonium (NH4+) containing aqueous liquid comprising (a) separating at least part of the ammonium as ammonium salt or concentrated ammonium salt comprising solution from the ammonium containing aqueous liquid, (b) decomposing at least part of the ammonium salt or salt solution into an ammonia (NH3) comprising gas and one or more other decomposition products, and (c) feeding at least part of the ammonia comprising gas to an fuel cell.
Claims18
A method for the production of electrical energy from an ammonium (NH4+) containing aqueous liquid comprising:
- a. separating from the ammonium containing aqueous liquid at least part of the ammonium as (i) ammonium salt or (ii) concentrated ammonium salt comprising solution;
- b. decomposing at least part of the ammonium salt into an ammonia (NH3) comprising gas and one or more other decomposition products;
- c. feeding at least part of the ammonia comprising gas to a solid oxide fuel cell (SOFC).
An apparatus for the production of electrical energy from an ammonium containing aqueous liquid comprising:
- a. a separator unit arranged to separate at least part of the ammonium as (i) ammonium salt or (ii) concentrated ammonium salt comprising solution from the ammonium containing aqueous liquid;
- b. a decomposition unit, arranged downstream of the separator unit, and arranged to decompose at least part of the ammonium salt into ammonia and one or more other decomposition products;
- c. a solid oxide fuel cell (SOFC), arranged downstream of the decomposition unit, and arranged to be fed with at least part of the ammonia from the decomposition unit.
