Study and design of a decentralized green ammonia production system from renewable hydrogen for agricultural applications

Abstract

Facing energy and climate challenges, green ammonia offers a promising pathway to decarbonise agriculture. This project studies and designs a decentralised green ammonia production system powered by solar photovoltaic energy. An integrated numerical model (PEM electrolysis, H2 storage, Haber-Bosch synthesis) is implemented in an interactive platform (Python, Dash, Plotly) enabling real-time visualisation of performance for all 58 Algerian wilayas. The techno-economic analysis includes CAPEX, OPEX, water cost, and LCOA. Threewilayas (Djelfa, Tipaza, Adrar) are compared: Djelfa shows the highest production and lowest LCOA, while Adrar suffers losses due to heat and dust. The platform serves as a decision-support tool for siting local green ammonia units.
