Solar ammonia

Partner institutions:

Ammonia production is one of the most important industrial processes providing ammonia for both fertiliser and explosive manufacture, with in excess of 120 million tonnes produced annually. Industrially, the catalytic Haber–Bosch process manufactures NH3 by shifting the reaction equilibrium of a N2/H2 gas mixture at high pressure (about 30 MPa) towards formation of ideally 22.7mol% NH3. Ammonia is reportedly, also one of the largest energy consuming processes requiring around 1% of the world's power production whilst around 2.3 tonnes of fossil fuel-derived CO2 are generated per tonne NH3 synthesised. We investigate pathways allowing for substitution of fossil fuels with concentrated solar radiation for lower-emission ammonia production.
