Implication

Economic model predicts blue ammonia production improves energy efficiency in Brazil's pre-salt region, suggesting a path to a sustainable blue economy.

Key Points

Evaluate the feasibility of blue ammonia production on very large floating structures in Brazil.
Feasibility analysis of producing blue ammonia offshore
Integration of autothermal reforming, CO₂ capture, and Haber–Bosch process
Development of a mass–energy balance and economic model
System targets specific energy demand of 7.2–7.8 GJ per ton of ammonia
CO₂ capture efficiency exceeds 90%
Net Present Value estimated at approximately USD 2 billion under realistic market conditions
