Why firms are racing to produce green ammonia

Ammonia is essential for fertiliser production but producing it is carbon intensive.

Plus, many, including Starfire Energy, hope to package the required tech in a space as small as a shipping container, so that it can be made near to the point of use - quite unlike the gargantuan Haber-Bosch plants operating today. Helga Flosadóttir, co-founder and chief executive, points out that while decarbonising fertiliser production is important, an even bigger goal lies in producing enough ammonia to use it as a fuel. As Josh McEnaney, president and chief executive of Nitricity in the US, explains, spreading ammonia on fields results in greenhouse gas emissions that could be avoided if we took a more direct approach to applying nitrogen, the crucial element that promotes plant growth, to the soil.
