“…When using soluble substrates (e.g. cheese whey, sucrose), it has been determined that CSTR is not the most appropriate design, these reactors often have washing of microorganisms caused by a cell growth rate lower than the rate at which the microorganisms leave the digester [10]. Even though biotrickling filters may be used to treat soluble and insoluble matter, insoluble matter may cause clogging problems [11].…”

The present work evaluated the biohydrogen production from a 0.4 L upflow anaerobic sludge blanket reactor type (UASB) operating at psychrophilic temperature (21 ±2 °C) at different feeding strategies varying hydraulic retention times (HRT) and sucrose concentration in the feeding. First strategy (24h/31c) fed semi-continuously 31 gsucrose L-1 at 24 h HRT; second strategy (12h/19c) fed semi-continuously 19 gsucrose L-1 at 12 h HRT; third strategy (4h/8c) fed continuously 8.3 gsucrose L-1 at 4 h HRT. After 70 days of operation, the UASB accumulated 65.44 L H2. The average HY for the whole operation during the three strategies was 62.6 NmL H2 gsucrose-1 , and average hydrogen content was 69.04%. In general terms, the best operation strategy was 12h/19c since it presented good set of results, the best HY (70.6 NmL H2 gsucrose-1) and a comparable hydrogen production rate (2.6 L (L d)-1) to that obtained in 4h/8c strategy (3.17 L (L d)-1). The average gross energy potential rate from the 12h/19c strategy was 46.21 kJ (L d)-1 , whereas energy heating losses were circumvented due to operation at psychrophilic regime. Indeed, psychrophilic or room temperatures should be broadly regarded as an effective alternative towards net energy gains in biohydrogen production.

“…Many hydrogen production pathways can be found in literature [ 45 , 53 , 54 , 55 ] and the selection thereof is mainly dependent on the feedstock used to produce hydrogen, the scale of production, and the available energy sources [ 2 ]. These pathways can be classified in various ways: The hydrogen source/feedstock (hydrocarbons or non-hydrocarbons) [ 2 , 3 , 56 , 57 ], the chemical nature and/or energy input [ 2 , 3 , 56 ] (thermochemical, electrochemical and biological [ 46 ]), the production method used [ 3 , 52 , 56 , 57 ] (its maturity level and efficiency) [ 2 ], the catalyst material [ 52 ], storage [ 51 ], the distribution mechanism (i.e., on-site generation or delivered) [ 53 , 56 ] and end use (e.g., hydrogen purity required) [ 50 ]. The choice of the hydrogen production pathway should take into account, (i) the hydrogen fuel quality grade required for end-use application and (ii) purification technology feasibility [ 2 ].…”

Recent Advances in Membrane-Based Electrochemical Hydrogen Separation: A Review

In this paper an overview of commercial hydrogen separation technologies is given. These technologies are discussed and compared—with a detailed discussion on membrane-based technologies. An emerging and promising novel hydrogen separation technology, namely, electrochemical hydrogen separation (EHS) is reviewed in detail. EHS has many advantages over conventional separation systems (e.g., it is not energy intensive, it is environmentally-friendly with near-zero pollutants, it is known for its silent operation, and, the greatest advantage, simultaneous compression and purification can be achieved in a one-step operation). Therefore, the focus of this review is to survey open literature and research conducted to date on EHS. Current technological advances in the field of EHS that have been made are highlighted. In the conclusion, literature gaps and aspects of electrochemical hydrogen separation, that require further research, are also highlighted. Currently, the cost factor, lack of adequate understanding of the degradation mechanisms related to this technology, and the fact that certain aspects of this technology are as yet unexplored (e.g., simultaneous hydrogen separation and compression) all hinder its widespread application. In future research, some attention could be given to the aforementioned factors and emerging technologies, such as ceramic proton conductors and solid acids.

Magnesium hydride is considered to be one of the most promising hydrogen storage materials, although it nevertheless has some problems, such as the high value of the activation energy of hydrogen desorption. To solve this problem, some scientists have proposed adding nanocarbon materials, in particular carbon nanotubes, to magnesium hydride. Currently, a detailed understanding of the mechanisms of obtaining composites based on magnesium hydride and carbon nanotubes is lacking, as is our understanding of the effect of nanocarbon additives on the activation energy and temperature of hydrogen desorption depending on the parameters of the composite synthesis. In addition, the data obtained at various values of milling parameters are very different, and in some works the effect of carbon nanomaterials on the hydrogen properties of magnesium hydride was not confirmed at all. Thus, it is important to determine the effect of nanocarbon additives on the properties of hydrogen storage of magnesium hydride under various milling parameters. This work is devoted to the study of the effect of nanocarbon additives on magnesium hydride and the determination of the dependences of the hydrogen desorption temperature and activation energy on the synthesis parameters. Composite powders containing MgH2 with 5 wt.% single-walled carbon nanotubes (SWCNT) were prepared using a planetary ball mill. The milling was carried out at various milling speeds, namely 300, 660, and 900 rpm. Results suggested that the structure of the nanotubes is preserved with prolonged grinding of magnesium hydride and SWCNT in a ball mill for 180 min at a relatively low grinding speed of 300 rpm. The composite obtained with these parameters has the lowest temperature of hydrogen desorption and an activation energy of H2 desorption of 162 ± 1 kJ/mol H2, which is 15% lower than that of the magnesium hydride MgH2 (189 ± 1 kJ/mol H2).
