Green ammonia has the potential to drastically reduce the carbon footprint needed to produce fertiliser vital for crop-growing. The production of ammonia for fertilisers – which has one of the largest carbon footprints among industrial processes – will soon be possible on farms using low-cost, low-energy and environmentally friendly technology.

This is thanks to researchers at UNSW Sydney and their collaborators who have developed an innovative technique for sustainable ammonia production at scale.

Up until now, the production of ammonia has relied on high-energy processes that leave a massive global carbon footprint – temperatures of more than 400 oC and pressures exceeding 200 atmospheres that account for 2 per cent of the world’s energy and 1.8 per cent of its CO2.
