Study Findings from Yasar University Provide New Insights into Hydrogen

January 31, 2014

By a News Reporter-Staff News Editor at Energy Weekly News -- A new study on Hydrogen is now available. According to news reporting originating from Izmir, Turkey, by VerticalNews correspondents, research stated, "In this study, hybrid renewable energy based hydrogen and electricity production and storage systems are conceptually modeled and analyzed in detail through energy, exergy and sustainability approaches. Several subsystems, namely hybrid geothermal energy-wind turbine-solar photovoltaic (PV) panel, inverter, electrolyzer, hydrogen storage system, Proton Exchange Membrane Fuel Cell (PEMFC), battery and loading system are considered."

Our news editors obtained a quote from the research from Yasar University, "Also, a case study, based on hybrid wind-solar renewable energy system, is conducted and its results are presented. In addition, the dead state temperatures are considered as 0 degrees C, 10 degrees C, 20 degrees C and 30 degrees C, while the environment temperature is 30 degrees C. The maximum efficiencies of the wind turbine, solar PV panel, electrolyzer, PEMFC are calculated as 26.15%, 9.06%, 53.55%, and 33.06% through energy analysis, and 71.70%, 9.74%, 53.60%, and 33.02% through exergy analysis, respectively."

According to the news editors, the research concluded: "Also, the overall exergy efficiency, ranging from 5.838% to 5.865%, is directly proportional to the dead state temperature and becomes higher than the corresponding energy efficiency of 3.44% for the entire system."
