Ammonium bicarbonate is a chemical compound made up of ammonium, which is a type of nitrogen, and bicarbonate, which is a form of carbon and oxygen. It is commonly used as a baking ingredient or as a cleaning agent. Full definition
This carbon - capture unit built by Alstom and dubbed the «chilled ammonia» process, consumes 25 - kilogram bags of baker's ammonia to strip CO2 from the cooled flue gas and then, by reheating the resulting ammonium bicarbonate, captures that CO2 and recycles the reconstituted ammonia back into the industrial process.

An incessant rumble also emanates from the regenerator stacks, as well, where steam heat and pressure combine to turn ammonium bicarbonate (part of the CO2 - stripping process) back into baker's ammonia (ammonium carbonate), siphoning off the captured CO2 in the operation. (scientificamerican.com)
«Sequestering carbon as ammonium bicarbonate or as urea is quite a smart idea,» says Walter Schmidt of the US Department of Agriculture in Beltsville, Maryland. (newscientist.com)
