    Optimal design of a Hydrogen Refuelling Station (HRFS) powered by Hybrid Power System
    (Elsevier Ltd, 2018) Gökçek M.; Kale C.
    The use of hydrogen as transportation fuel is considered to be a favourable alternative to fossil fuels. It is believed that the development of fuel cell vehicles will greatly facilitate reduction of greenhouse gas emissions from the transportation sector due to the fact that these vehicles are fuelled by hydrogen, which can be produced by a wide range of processes using renewable energy sources. In order to promote the use of fuel cell vehicles, it is imperative to build the necessary facilities to support this need in the near future, including hydrogen refuelling stations powered by renewable power generation systems. In this study, techno-economic analysis was performed for a hydrogen refuelling station powered by two types of hybrid renewable power generation systems (wind-photovoltaic-battery and wind-battery systems) which will be installed on the island of Gökçeada, Turkey. The analysis was carried out to assess the feasibility of the hydrogen refuelling station to refuel 25 vehicles on a daily basis throughout the year, using HOMER software. Based on the results, the levelized cost of hydrogen for the hydrogen refuelling station powered by the hybrid wind-photovoltaic-battery and wind-battery systems is $ 8.92/kg and $ 11.08/kg, respectively. The levelized cost of hydrogen was also determined for different variable parameters (wind speed, wind turbine hub height, solar irradiance, and project lifetime). It is concluded that the hydrogen refuelling station powered by the proposed renewable power generation systems may be feasible for the chosen site. © 2018 Elsevier Ltd

    Techno-economical evaluation of a hydrogen refuelling station powered by Wind-PV hybrid power system: A case study for İzmir-çeşme
    (Elsevier Ltd, 2018) Gökçek M.; Kale C.
    Hydrogen fuelling station is an infrastructure for the commercialisation of hydrogen energy utilising fuel cells, particularly, in the automotive sector. Hydrogen fuel produced by renewable sources such as the solar and wind energy can be an alternative fuel to depress the use of fuels based on fossil sources in the transport sector for sustainable clean energy strategy in future. By replacing the primary fuel with hydrogen fuel produced using renewable sources in road transport sector, environmental benefits can be achieved. In the present study, techno-economic analysis of hydrogen refuelling station powered by wind-photovoltaics (PV) hybrid power system to be installed in İzmir-Çeşme, Turkey is performed. This analysis is carried out to a design of hydrogen refuelling station which is refuelling 25 fuel cell electric vehicles on a daily basis using hybrid optimisation model for electric renewable (HOMER) software. In this study, National Aeronautics and Space Administration (NASA) surface meteorology and solar energy database were used. Therefore, the average wind speed during the year was assessed to be 5.72 m/s and the annual average solar irradiation was used to be 5.08 kW h/m2/day for the considered site. According to optimisation results obtained for the proposed configuration, the levelised cost of hydrogen production was found to be US $7.526–7.866/kg in different system configurations. These results show that hydrogen refuelling station powered by renewable energy is economically appropriate for the considered site. It is expected that this study is the pre-feasibility study and obtained results encougare the hydrogen refuelling station to be established in Turkey by inventors or public institutions. © 2018 Hydrogen Energy Publications LLC
