Journal ArticleDOI
TL;DR: In this paper, the authors compare the hydrogen production rates of various bio-hydrogen systems by first standardizing the units of hydrogen production and then calculating the size of biohydrogen system that would be required to power proton exchange membrane (PEM) fuel cells of various sizes.

TL;DR: In this article, an experimental assessment of a hydrogen-based regenerative (electrolyser-fuel cell) system is presented, which is conducted on a residential scale Integrated Renewable Energy Experiment (IRENE) test-bed under conditions that are representative of the real demands that would be placed on a solar based, regenerative system, with a focus on dynamic operation under transients in both load and renewable energy supply profiles.

TL;DR: In this paper, the current state of the steam reforming process of ethanol, examines different catalysts, and makes a comparative analysis, and concludes that Co/ZnO, ZnO+Al2O3, Co/CeO2, Ni/La 2O3−Ni/La2O2−Al2E3, and Ni/E3−E2E2−E3 performed the best in terms of steam reforming of ethanol.
Abstract: Hydrogen is considered to be the most viable energy carrier for the future. Producing hydrogen from ethanol steam reforming would not only be environmentally friendly but also would open new opportunities for utilization of renewable resources, which are globally available. This paper reviews the current state of the steam reforming process of ethanol, examines different catalysts, and, finally, makes a comparative analysis. Different catalysts have been used for the steam reforming of ethanol. Depending on the type of catalysts, reaction conditions, and the catalyst preparation method, ethanol conversion and hydrogen production vary greatly. It was observed that Co/ZnO, ZnO, Rh/Al2O3, Rh/CeO2, and Ni/La2O3−Al2O3 performed the best, in regard to the steam reforming of ethanol. Currently, hydrogen production from ethanol steam reforming is still in the research and development stage.
