Trends in bio-hydrogen generation – A review

Abstract

This paper reviews the research work carried out in bio-hydrogen generation from a renewable source, namely biomass. Bio-hydrogen production has several advantages when compared to photoelectrochemical or thermo-chemical processes due to the low energy requirement and investment cost. Hydrogen seems to be the future energy carrier by the virtue of renewable. Bio-hydrogen production processes also involve the production of CO 2 . However, this CO 2 was released from biomass, in which it was recently taken up, which is in contrast to fossil fuels, where the carbon dioxide has taken millions of years to build up, while the release takes only decades. So the duration of the carbon cycle is very important in view of sustainability.

Next‐Generation Biofuels: Survey of Emerging Technologies and Sustainability Issues

“…Biochemical technologies for biohydrogen production [172][173][174][175][221][222][223] started to receive attention after the oil crisis in 1970s. [157] Notwithstanding the steadily increasing interest and R&D on solar fuels, no commercial applications exist so far.…”

Hydrogen Generation by Water Splitting

“…Apart from Scenedesmus obliquust that was used by Gaffron and Rubin [137], green algae species including Chlamydomonas reinhardtii and Chlamydomonas moewusii have also proven useful [122,141,174]. Among these a maximum efficiency of hydrogen production has been observed in Chlamydomonas reinhardii.…”

“…Hydrogen Generation by Water Splitting Some of the heterocystous cyanobacteria strains used for hydrogen evolution include Anabaena Azollae, Anabaena variabilis, Anabaena cylindrica, Nostoc muscorum, Nostoc spongiaeforme, and Westiellopsis prolifica [174]. In the early 1970s Beneman and coworkers demonstrated that hydrogen and oxygen could be produced simultaneously for several hours using Anabaena cylindrica in a nitrogen deficient atmosphere [183,184] by flowing inert gas.…”

Rapid Reductive Dechlorination of Trichloroethene in Contaminated Ground Water Using Biostimulation Agent, BD-1, Formulated from Canola Oil

“…Sequence analysis of the DGGE bands from 2 to 21 days showed that many of the predominant bands were affiliated with known fermentative bacteria, including the genera Trichococcus 17 bands #10 and 11 , Sporotalea 18 band #17 , Clostridium bands #8 and 19 and Klebsiella 19 bands #9 and 16 . These bacteria are known to produce hydrogen from fatty acids with VFA accumulation 20 . The other predominant bands were also affiliated with the genera Desulfovibrio band #1 , Azovibrio band #2 , Thiobacillus band #3 , Propionivibrio bands #4 and 5 , Enterobacter bands #12, 13, 14, 15, and 20 , and Pantoea band #18 .…”
