Evaluation of solar power application onboard from the perspective of carbon intensity indicator

Paper i proceeding, 2026

Shipping has recently focused on increasing energy efficiency and reducing environmental impact since it considerably increases atmospheric emissions due to fossil fuel use and its huge transportation capacity. In this regard, some strategies are being investigated, and integrating renewable power sources into a ship is one of the significant solutions. Solar power is promising since it produces green energy and environmentally friendly shipping for maritime businesses. This study examines solar power application on a Ro-Ro ship from the perspective of carbon intensity indicator rather than revealing its contributions to fuel consumption and emission. Calculations are presented where the information on parameters is taken from the literature. As a result of the analysis, it is found that although the integration of solar power improves the energy rating from E level to D level, it is insufficient to meet long-term energy efficiency requirements for the case study ship.
