Biohydrogen is a promising energy source since it is clean and renewable. The HYVOLUTION project (EU 6th Framework Programme) is aimed to develop an integrated process in which biomass is utilized for the biohydrogen production in two steps. In the first step biomass is fermented to acetate, lactate, CO2 and hydrogen by an extreme thermophile (Caldicellulosiruptor saccharolyticus). In the second step, acetate and lactate is converted to hydrogen and CO2 by photofermentation with purple nonsulfur bacteria. The present work is based on a case study of potato steam peels hydrolysate. The photofermentability of Rhodobacter capsulatus was investigated with different adjustments on dark fermenter effluent of potato steam peel hydrolysate. The highest yield (31 mgH(2)/gsubstrate.) and productivity (1.13 gH(2)/m(3).h) were obtained after buffer, molybdenum and iron addition. This study showed that PSP hydrolysate as biomass is suitable for the integration of dark fermentation and photofermentation for efficient and sustainable hydrogen production in photobioreactors by phototrophic bacteria.

Hydrogen and poly-beta hydroxy butyric acid production and expression analyses of related genes in rhodobacter capsulatus at different acetate concentrations Özsoy, Burcu; Gündüz, Ufuk; Department of Biology (2012) Hydrogen, which is a clean energy source, is one of the alternatives for fossil fuels. Biological hydrogen production is one of the hydrogen production methods. Rhodobacter capsulatus is a photosynthetic bacterium that produces hydrogen via photofermentation. R. capsulatus can also synthesize some valuable by-products such as Poly-beta- hydroxy butyric acid (PHB), which is a biodegradable bioplastic. In a two stage biohydrogen production system, which is combination of dark fermentation and photofermentatio...
Ethanol steam reforming with zirconia based catalysts Arslan, Arzu; Doğu, Timur; Department of Chemical Engineering (2014) Production of hydrogen, which has been considered as an environmentally clean ideal energy carrier, from abundant energy resources cleanly and renewably is essential to support sustainable energy development. Hydrogen production from bio-ethanol by steam reforming process is a promising approach, since bio-ethanol is the most available bio-fuel in the world and steam reforming of ethanol yields formation of 6 moles of hydrogen per mole of ethanol. Support material used for nickel based catalysts plays a cru...
Design of Electrical Submersible Pump system in geothermal wells: A case study from West Anatolia, Turkey Aydın, Hakkı; Merey, Şükrü (Elsevier BV, 2021-5-12) Geothermal is defined as one of the renewable and sustainable energy sources. The sustainability of geothermal wells is highly dependent on the pressure drive mechanism and non-condensable gas (NCG) content of the produced geothermal fluid. Pressure decline and decline of non-condensable gases are commonly observed in geothermal production wells, which is unfavorable for wells’ lifetime. Electrical Submersible Pumps (ESP) are one of the solutions for extending the lifetime of geothermal wells. In this study...
Hydrogen production by hup(-) mutant and wild-type strains of Rhodobacter capsulatus from dark fermentation effluent of sugar beet thick juice in batch and continuous photobioreactors Uyar, Basar; Gurgan, Muazzez; Ozgur, Ebru; Gündüz, Ufuk; Yücel, Ayşe Meral; Eroglu, Inci (2015-10-01) Photofermentative production of hydrogen is a promising and sustainable process; however, it should be coupled to dark fermentation to become cost effective. In order to integrate dark fermentation and photofermentation, the suitability of dark fermenter effluents for the photofermentative hydrogen production must be demonstrated. In this study, thermophilic dark fermenter effluent (DFE) of sugar beet thick juice was used as a substrate in photofermentation process to compare wild-type and uptake hydrogenas...
Hydrogen production from ethanol over mesoporous alumina based catalysts and microwave reactor applications Gündüz, Seval; Doğu, Timur; Department of Chemical Engineering (2014) Due to fast depletion of fossil fuel resources and related environmental impact of CO2 emissions, the interest in hydrogen as a clean energy carrier has recently increased. Hydrogen production from bio-ethanol, which already contains large amount of water, by steam reforming process, has shown excellent potential with CO2 neutrality and renewability. Steam reforming of ethanol (SRE) process has a highly complex reaction network including numerous side reactions which decrease hydrogen yield and have a negat...
