This technology utilizes cheap and readily available salts such as magnesium chloride (MgCl2) and particulate supports to absorb ammonia selectively as the ammonia is formed. Key Features and Benefits of this technology when compared to conventional Haber Bosch processes are: • Lower operating pressures • Lower operating costs • Lower capital costs • Small scale ammonia production Other key features and benefits of this technology include: • Ammonia is a more efficient storage medium than hydrogen • Cost effective storage medium for electrical energy Once absorbed, ammonia is rapidly released from the salt by simply lowering the pressure. Traditional ammonia synthesis catalysts and absorbents can be combined into a single absorbent bed system. It is possible to achieve greater than 85% conversion to ammonia in a single operation—much greater than the typical ~15% conversion currently achieved. Significantly lower reaction pressures are expected. Such high conversions and lower reaction pressures eliminate the necessity for costly recycle streams and high-pressure reaction vessels, leading to lower energy requirements, and reduced capital costs. In addition, where excess electrical energy is available, this technology could be used to store energy as ammonia.
