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.
