The industrial production of ammonia is a highly carbon-emitting process that contributes to more than 1% of global greenhouse gas emissions. In the long transition to net-zero ammonia production, blue ammonia technologies that use a low-carbon approach by integrating carbon capture and storage solutions with conventional hydrogen- and ammonia-making steps are considered promising interim solutions. This Process Economics Program (PEP) review provides a comprehensive techno-economic assessment of the Casale SA (Casale) Blue Ammonia A6000CC™ technology. The production economics assessment in this report is for a plant based at a US Gulf Coast (USGC) location, with an annual capacity of 4,000 metric tons per day (t/d) or 2,896.7 million pounds of liquid ammonia every year and a total carbon dioxide (CO2) capture rate (Scope 1 emissions) of more than 90%. An iPEP Navigator® module, which is an Excel-based computer costing model developed by S&P Global Commodity Insights, is also attached with this report to allow quick calculation of the process economics in other major regions of the world.
This technological and economic assessment of the A6000CC™ process is PEP’s independent interpretation of the commercial process based on information presented in the open literature, such as patents or technical articles, and may not reflect in whole or in part the actual plant configuration. We do believe that this assessment is sufficiently representative of the process and process economics within the range of accuracy required for a conceptual process design evaluation. This review will be a valuable resource for planners, producers and designers who are looking for an authentic evaluation of capital and production costs for blue ammonia production.
