Blue Ammonia
★ Gray Ammonia for which by-product
CO₂ has been captured and stored,
reducing climate impact
CO₂
Green Ammonia
Produced with hydrogen from
water electrolysis powered by
renewable energy
Technology exists today to use LOWER- or ZERO-CARBON AMMONIA to reduce
CO:
By simply replacing conventional ammonia in existing uses, which is one of the most
widely used industrial chemicals on the planet
As a fuel for
✓ Electricity generation to power remote telecommunication towers or to provide
electricity to back up supporting intermittent renewable power generation, like
wind and solar
“Greening” maritime transportation
Decarbonizing heating and cooling
✓
Internal combustion engines, turbines and batteries
As a safe, efficient mode for hydrogen transport
