The intensified global effort to mitigate climate change is currently focused on significantly reducing carbon dioxide emissions, exemplified by the European Union's target to cut greenhouse gas emissions by 55% by 2030. While ammonia acts as a critical carbon-free energy carrier in these decarbonization strategies, its conventional production relies heavily on fossil fuels. Consequently, a sustainable method utilizing nitrogen-rich organic waste has been proposed to facilitate green ammonia production. The primary goal of this study is to assess the feasibility and capacity for producing green ammonia from animal waste within Ukraine. This assessment aims to present a promising, sustainable alternative to the traditional Haber-Bosch method by leveraging agricultural byproducts. The proposed technical approach involves the sorption of ammonia from the gas phase of a biogas reactor using a monoammonium phosphate (MAP) solution, which results in the formation of diammonium phosphate (DAP). The process utilizes thermal energy from a cogeneration plant running on biogas to heat the DAP, thereby releasing ammonia gas and regenerating the MAP for continuous operation. The study estimates that this method could yield up to 263,610 tons of ammonia annually in Ukraine, a figure comparable to the nation's conventional ammonia output in 2019. Geographic analysis identified the Vinitskaya, Cherkasy, and Kyiv regions as having the highest production potential due to their substantial agricultural activity and the availability of organic waste. This innovative approach allows for the generation of clean energy carriers from waste, potentially enhancing Ukraine's energy security. Furthermore, the implementation of this technology supports broader global decarbonization efforts by replacing fossil-fuel-based production methods with renewable alternatives.
