Comparative study of PV/PEM fuel cell hybrid energy system based on methanol and water electrolysis

Budak, Yagmur
In this study, we investigated the comparative analysis of a solar-fuel cell hybrid system based on water and methanol electrolysis. The proposed system comprises PV, electrolyzer and proton exchange membrane fuel cell (PEMFC). The hybrid system is designed to supply the hydrogen (H-2) needed of the PEMFC system and also to fulfill the H-2 requirement of other applications. The actual data of solar irradiation of Izmir, Turkey are used in the simulation. The methanol and water electrolyzers were designed for 1.2 kW PEMFC H-2 demand which were met a house-hold energy requirement. Analyzes show that the use of the methanol electrolyzer can produce 27% more H-2 than the water electrolyzer. According to the study, it was determined that the methanol-based hybrid system offered a viable option for self-sustaining in household application.


Kinetics of hydrogen generation from hydrolysis of sodium borohydride on Pt/C catalyst in a flow reactor
Boran, Asli; Erkan, Serdar; Özkar, Saim; Eroglu, Inci (Wiley, 2013-04-01)
Here, we report the results of a kinetic study on the hydrogen generation from the catalytic hydrolysis of sodium borohydride in a differential flow reactor. As catalyst platinum supported on carbon (Pt/C) was used in two forms: either as powder or coated on carbon cloth. For optimization of the system several parameters such as sodium hydroxide concentration, sodium borohydride concentration and the flow rate of the feed solution were varied. It was found that the H2 generation rate increases with an incre...
Economical Evaluation of an Oil Field Reservoir
Kök, Mustafa Verşan (Informa UK Limited, 2011-01-01)
In this study, economical evaluation of an oil field reservoir was performed using software. The software used in this study consists of different sub-programs to determine recoverable oil, recovery factor, initial and final productions, production rates, and original oil and gas in place for different types of reservoirs. Recovery efficiency was found to be 29% for water drive and 4.78% for solution gas drive reservoirs. In decline curve analysis, initial and final production rates were obtained as 40 and ...
Statistical Approach of Two-three Parameters Rheological Models for Polymer Type Drilling Fluid Analysis
Kök, Mustafa Verşan (Informa UK Limited, 2010-01-01)
In this study, 45 KCl/polymer type of drilling fluid samples were prepared for statistical analysis. Six difference (600, 300, 200, 100, 6, and 3) readings at standard Fann viscometer speeds were determined in order to estimate the rheological model parameters of our different models, as follows: Bingham Plastic, Power-Law, Hershel-Bulkley, and Robertson-Stiff. Parameters of the rheological models are estimated by explicitly solving the required number of equations simultaneously. Different statistical tech...
Evaluation of hybridsolar-wind-hydrogenenergy system based on methanol electrolyzer
Budak, Yagmur; DEVRİM, YILSER (Wiley, 2020-10-01)
In this study, it is aimed to meet the annual electricity and heating needs of a house without interruption with the photovoltaic panel, wind turbine, methanol electrolyzer, and high temperature proton exchange membrane fuel cell system. The system results show that the use of the 2 WT with 18 PV was enough to provide the need of the methanol electrolyzer, which provides requirements of the high temperature proton exchange membrane fuel cell. The produced heat by the fuel cell was used to meet the heat requ...
Feasibility study of heavy oil field
Kök, Mustafa Verşan (Informa UK Limited, 2008-01-01)
In this study, application of different enhanced tertiary oil recovery methods were applied considering fluid properties and reservoir characteristics of the heavy oil field. Effect of different oil and inflation rates were analyzed considering project economic life, pay out time, cash flow, and profit to investment ratio for steam flooding and CO2 methods. CO2 injection is found to be more profitable than the steam injection due to the high cost of steam injection operations and reservoir depth.
