Tomorrow: Hybrid plants for greener ammonia

Benefits: ? Waste streams are now valuable streams. ? Decrease specific natural gas consumption by utilising electrical power.

Compared to present configuration: ? 22% lower natural gas consumption! ? 75% lower CO2 emissions in flue gas! ? Similar investment. ? Allows for excess energy storage.
