    Advancements and current technologies on hydrogen fuel cell applications for marine vehicles
    (Pergamon-Elsevier Science Ltd, 2022) Surer, Meryem Gizem; Arat, Huseyin Turan
    Maritime industry has led renewable energy sources for the greener environment and efficient vehicles that effect by increasing population and energy demands. Hydrogen is one of the most popular of these renewable energy sources and one of the most favourable research area, worldwide. In this study, authors reported the usage of hydrogen fuel cells in marine transport as main power forwarder, their advantages and challenges under the lights on state of art and furthermore new technologies perspective. The latest research activities, hydrogen production and storage methods with challenges are analyzed and the developments of fuel cell based marine vehicles are discussed. In detailed, newly approachment of electrolyses from seawater for sustainable fuel necessity is discussed. As a result, this forseen study is important in terms of handling energy from seawater and compiling the latest technology for marine transport. (c) 2022 Hydrogen Energy Publications LLC.

    Energy and exergy analysis of hydrogen production from seawater using waste heat recovery system on a model ship
    (Inderscience Enterprises Ltd, 2024) Surer, Meryem Gizem; Arat, Huseyin Turan
    Marine transportation has been the subject of many studies on the green environment. 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.
