Efficient integration of the carbon capture and storage (CCS) process in power generation plants can help reduce global CO 2 emissions. Hydrate technology has emerged as one of the most promising technologies for the separation and sequestration of CO 2 . This paper compares the process energy consumption of different CO 2 capture techniques, gas transportation, and sequestration methods integrated into a pre-combustion power plant. Process modeling of a conceptualized hydrate technology-based CCS process is simulated using a coupled TRNSYS simulation software and engineering equation solver. The performance in efficiency, energy consumption, and potential energy penalty is evaluated and analyzed for three study cases. Furthermore, the energy requirement for transporting and sequestrating CO 2 in hydrate as hydrate slurry is evaluated and compared to supercritical transportation and sequestration. The results obtained show that the energy consumption of hydrate-based gas separation amounts to 70 % of the total energy consumption for hydrate-based CO 2 capture, transportation, and sequestration.
