Transforming Ammonia Production: Evaluating Energy Trends and Carbon Management Strategies in Trinidad and Tobago

The ammonia industry of Trinidad and Tobago (T&T) remains vital to its national economy, consuming approximately 17% of the country’s total natural gas supply as of 2023. Given the critical need to align the sector with global decarbonization efforts, this study evaluates the economic resilience, energy efficiency trends, and environmental footprint of the ammonia industry over two decades (2004–2023). Findings indicate that national ammonia plant utilization rates have declined to roughly 70% due to persistent natural gas supply constraints, causing energy intensity to rise to approximately 40.41 MMBtu per metric ton of ammonia (NH3). However, improved production levels closer to the design capacity positively correlate with enhanced operational efficiency. Employing the IPCC (2006) Tier 2 guidelines for greenhouse gas (GHG) accounting, this study demonstrates that the strategic utilization of ammonia-derived CO2 in existing downstream processes (urea and methanol synthesis) can significantly decrease the sector’s net CO2 emissions by approximately 60–80%. Furthermore, the analysis identified promising decarbonization pathways, including the adoption of carbon capture, utilization, and storage (CCUS), renewable hydrogen integration, and targeted process optimization strategies. This research emphasizes the necessity of robust, data-driven policy frameworks, strategic public-private sector partnerships, and proactive international collaboration to effectively navigate the transition toward a lower-carbon ammonia sector. These measures are crucial for T&T in both environmental stewardships and their competitive advantage amid evolving global carbon market conditions.
