| Summary: | Trinidad and Tobago’s (T&T) conditional commitment to the Paris Agreement requires an overall power emission avoidance (EAT) of 28.7 MtCO2-e from Business-As-Usual by 2030, dependent on international financing. T&T has outlined several initiatives to achieve this, including zero-carbon renewable energy (RE) introduction. However, other technologies such as Carbon Capture and Storage (CCS) can also be used in support of achieving EAT. Using a specific scenario (S3), this study assesses the techno-economics of CCS within the sector to minimize the requirement of RE using a carbon measuring tool called Carbon Emission Pinch Analysis (CEPA) to achieve EAT. Local power plants were screened, and a CCS retrofit was then technically designed using a validated software called Aspen HYSYS. Multi-period CEPA methodology was then applied to quantify ∼17% of grid energy from RE along with CCS to achieve EAT. Economic models were also used to determine the grid unit cost of emission abatement for S3 to be 64 USD/tCO2-e; a doubling of initial projection requirements. With T&T’s current dynamics, these findings can help guide actions to reduce the requirements of RE onto the grid through the supplemental introduction of CCS to achieve its EAT. |
