Making fertilizer is a major source of emissions; a cleaner route is emerging. Green ammonia uses renewable electricity instead of fossil fuels for synthesis. It could decarbonize a pillar of the food system.
A dirty process
The footprint is large. Conventional ammonia synthesis burns fossil fuels. Emissions are significant.
Renewable route
The fix is electric. Green hydrogen feeds ammonia made with clean power. Carbon is avoided.
Food and fuel
Uses are broad. Ammonia fertilizes crops and may carry hydrogen energy. Demand is vast.
Cost barrier
Economics lag. Green ammonia costs more today. Scale must lower prices.
Catalyst research
Chemistry advances. Better catalysts could ease conditions. Efficiency rises.
Early plants
Deployment starts. First facilities are being built. The transition begins.
The bottom line
Green ammonia uses renewable electricity to decarbonize fertilizer synthesis, a major emissions source. It also may carry hydrogen energy. Cost is the barrier, and first plants are being built.
