Contributing to these studies, a system that uses electricity obtained from the waste heat of a diesel engine to obtain hydrogen has been designed. Concept ship design, energy and exergy analysis was applied. In the results evaluation of the exergy destruction, the components having the highest exergy destruction in the Rankine system were the turbine with 97%, and the system producing hydrogen from seawater was the electrolyser with 54%. As a result, the system of using seawater in hydrogen production seems feasible and can be used as a storage option.eninfo:eu-repo/semantics/closedAccesswaste heat recoveryseawaterhydrogenRankine cycleexergyArticle44110.1504/IJEX.2024.1387412-s2.0-85195058379Q3WOS:001235678900004Q4
