Ammonia is recognized as a carbon-free, energy-dense medium for hydrogen transport and energy storage, but conventional synthesis contributes significantly to greenhouse gas emissions. MIT's Energy Initiative conducted an extensive analysis incorporating country-specific economic factors and production technologies—including gray, blue, and green ammonia—to evaluate impacts across 63 countries. Their study delineates the tradeoffs between carbon emissions reductions and cost increases associated with different production pathways.
Key findings highlight that switching to ammonia produced with carbon capture could reduce emissions by approximately 71% at a moderate cost increase, while fully renewable ammonia production offers near-complete decarbonization with higher costs. The research addresses prior data fragmentation by harmonizing environmental and economic metrics across regions and technologies, providing a valuable resource for policymakers and industry stakeholders aiming to develop sustainable ammonia fuel economies.
