Green Hydrogen for Renewable Ammonia

Improving global food supply and crop yield with green hydrogen

Our PEM electrolysers can be used to sustainably produce ammonia, helping to decouple production form fossil fuels.

Ammonia is one of the most highly produced inorganic chemicals.

Conventional production of ammonia (NH3) is a large scale industrial process, which uses hydrogen derived from natural gas.

Currently, 5% of global natural gas consumption is used to make ammonia (2% of world energy) causing it to contribute significantly to greenhouse gas emissions. Urea is a nitrogen-rich fertiliser made from ammonia and carbon dioxide. With the growing global population and demand for foodstuffs increasing, together with less acreage being dedicated to crop cultivation, 50% of global food production currently relies on the use of ammonia-based fertilisers to increase crop yields.

Ammonia and urea fertiliser can be produced sustainably by using hydrogen derived by electrolysis of water using a renewable electricity supply and a PEM electrolyser. This decouples ammonia production from fossil fuels. In the case of urea, it also decarbonises the process further, as it provides a means of utilising waste carbon dioxide.

Renewable hydrogen offers decentralised local fertiliser production opportunities, which improves security of supply and crop yield for a growing world population as well as price stability (removing the link to fossil fuel price volatility).
