This study proposes a novel Energy Efficiency Design Index (EEDI) estimation method considering the Onboard Carbon Capture and Storage (OCCS) system. The OCCS selectively captures and stores carbon dioxide (CO 2) contained in exhaust gas emitted from the internal combustion engines of a ship.
ESN features an integrated bottom-up approach that combines energy system modeling with streamlined life cycle assessment techniques to quantify the carbon footprint of all components in a localized energy system. The lifecycle phases of each component, including production, operation, and end-of-life treatment, can be considered.
