    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.

    Recycling and reusing batteries: A significant way for effective sustainability of FCEVs and EVs
    (Pergamon-Elsevier Science Ltd, 2023) Arat, Huseyin Turan
    In the last 20 years, the transportation sector has enabled the technology to evolve in its direction with both environmental and energy efficiency in the use of electric and fuel cell vehicles. The two important components of these vehicles are the batteries and electric motors. The batteries are produced within a certain life cycle, and unfortunately it is not possible to use them without conversion/recycling. In this study, the crucial importance of battery recycling/reusing is underliying and last researches will be given about battery recycling, above next ten years. Recommendations and future forseen advices will be presented about the current state of battery recycling technology, how recycling systems exist in different batteries, and the future of battery recycling standart. As a result, battery recycling and reusing for fuel cell and electric vehicles is considered to be an important keypoint in terms of both envirenmontial, economical and technologial menner for the transportation sector in the next decades.(C) 2023 Hydrogen Energy Publications LLC.
