Conventional modes of transportation, that are long-established in the market, utilize fuels such as natural gas, gasoline and diesel, that are derived from crude oil, a nonrenewable resource. The overconsumption of fossil fuels has led to the depletion of their reserves, which, in conjunction with the negative effects to earth’s climate has made the transition to renewable alternatives resources urgent. That is why there is a shift towards renewable energy sources that are perpetual, and their utilization has a minimal environmental impact. In accordance with this approach, hydrogen seems to be an optimal option to deal with the problem of the climate crisis that has surfaced since years ago and has escalated in the recent years. Hydrogen, as a transportation fuel has been the subject of research from both academia and industry, and Fuel Cell Electric Vehicles (FCEVs) have matured and compete with other technologies for a place in the market in the years to come. The current diploma thesis is a techno-economic study of green hydrogen production via water electrolysis, which occurs in the Hydrogen Refueling Station (on-site HRS) and utilizes renewable electrical energy, retrieved from wind turbines. The research is looking into the modelling of the PEM electrolyzers and the optimal determination of model parameters (the exchange current density, the transfer coefficient and the correction of the ohmic resistance). For model validation purposes, experimental data were collected from the open literature. To this end, 19 case studies from the literature were examined, that are extensively analyzed in Chapter 4. The model adequacy is tested based on the ability of the proposed model to reproduce the experimentally derived polarization curve, which is a representation that illustrates the influence of current density on voltage. Important to this study are two more performance curves: the specific (per kg of H2 produced) electrical energy consumption of the PEM electrolyzer as a function of current density and the ... |
