This model facilitates discourse among industry stakeholders, policymakers, and financial institutions by dissecting the economic aspects of green ammonia production. It offers comprehensive cost estimates throughout the value chain, from production to off-take, for two key sectors: fertilizer and shipping. The tool delineates the cost breakdown for each sector, accounting for variations in time, location, and policy dynamics such as carbon taxation. The Excel tools “PtX Model Shipping” and “PtX Model Fertilizer” enable country-specific cost estimations, with the report showcasing findings from Brazil, South Africa, and Namibia. The manual provides instructions for adapting the model to different countries and specific scenarios, offering limitless possibilities for analysis. The Green Hydrogen Business Alliance commissioned SYSTEMIQ for the tool and the report.
