Antropogenic waste CO2 and NH3 both provide enormous environmental challenges. The amount of CO2 emitted by fossil fuel power plants is now about an order of magnitude larger than the NH3 processed by waste water treatment plants but the NH3 production is growing faster than CO2 production. Recent experimental and theoretical studies have established that CO2 and NH3 react without additional energy input to form carbamic acid, NH2COOH, which exists primarily as a dimer when adsorbed on a cryogenic surface. Might it be possible to react effluent streams of CO2 and NH3 to form carbamic acid and then to store the carbamic acid (or use it as a source for other industrial chemicals)?
