Environmental implications of biohydrogen based energy production from steam reforming of alcoholic waste

Abstract

[EN] Nowadays, there is an increasing demand for energy in the world. With an energy system still based on fossil fuels, a paradigm shifts towards clean energy production based on available renewable resources is necessary. Hydrogen is a high-quality energy carrier that can be used with great efficiency and is expected to acquire a great importance in the next generation of fuels. This study aims to analyze the potential environmental impacts associated with the steam reforming of alcoholic waste from distilleries to produce clean electricity by using the Life Cycle Assessment methodology. The main findings from this study reported that the global environmental profile is better than other alternatives more common as sanitary landfill or incineration. In terms of some impact categories as Abiotic and Ozone Depletion, Acidification and Eutrophication, steam reforming of alcoholic waste performed better profiles than other processes that produce hydrogen from diverse feedstocks.
