This work aims to study the production of Green Ammonia (Green-NH3) from a plant solely powered with Renewable Energy (RE) sources. The main current challenge green ammonia plants is dealing energy intermittency and unpredictability RE sources while ensuring steady state avoid damaging non-flexible Haber Bosch (HB) catalytic reactor. delivers novel Techno-Economic (TE) modeling approach aiming optimize design operation pilot-scale G-NH3 plant. proposed TE model takes into consideration sources, by considering different site locations consistent yearly meteorological data. Additionally, ensure continuous power supply HB reactor, uses an original Management Strategy (EMS) adequately dispatch available Charge/Discharge Storage Systems (ESS). performances were evaluated two Key Performance Indicators (KPIs): Load Factor (LF) Levelized Cost (LCOA). results this indicated that implemented EMS allowed efficiently reduce fluctuation allocating time slots, which consequently increased LF 56% 65%, depending on type configuration. Consequently, increase in lead reduction overall cost plant, as yield overweight investment operational costs increase. PV/Battery scenario was found be most optimal entailing 6 MW PV coupled 11 MWh Battery capacity LCOA 774 $/tNH3. Finally, forecast estimate projected between 2021 2050, predicted potential down 250 $/tNH3, suggests year 2030, expected economically competitive conventional fossil-fuel based processes.
