Hydrogen production on Utsira
The hydrogen plant on Utsira has started producing electricity. This means that the 10 households in the island community west of Karmøy are one step closer to becoming a selfsufficient hydrogen society. From the summer, 10 of the households on the island of Utsira will get all their electricity in the form of renewable energy. This is the world's first full-scale autonomous renewable ...

Coupling the nickel–iodine–sulphur cycle with a nuclear reactor
Nuclear hydrogen production is a technically feasible and economically viable option for addressing future energy needs. Several projects have been started on the co–generation of hydrogen and electricity from nuclear energy. In this report, the nickel sulphur iodine (NIS) cycle, a thermochemical water splitting cycle originally developed in ENEA for solar hydrogen production, was studied to be ...

Energy and exergy analyses of a steam reforming process for hydrogen production
Hydrocarbon steam reforming is an important process for hydrogen production. In petroleum refineries, steam reforming is most commonly used for hydrogen production from naphtha and light hydrocarbon gases (methane, ethane and propane). Since the hydrocarbon steam reforming system is one of the highest energy intensive systems in a petroleum refinery it should be directed to a more efficient use ...

Modification of dolomite for hydrogen production via catalytic gasification of residue derived from biomass hydrolysis
Calcined dolomite is a good catalyst in terms of its activity for gasification of residue derived from biomass hydrolysis for hydrogen production, whereas its fragility can cause trouble during operation. A novel modification method aimed at improving the strength of the calcined dolomite has been presented using magnesium nitrate as the modifier, which was introduced into the dolomite via a ...

Biological hydrogen production: effects of inoculation and production media
In this work inoculation media are selected as potato, glycerine and milk to investigate the best storage condition that is important to maintain microorganism activity and stable hydrogen production performance. Cheese whey, potato and enriched potato (with additional glucose and CaCO3) are used as the production media and their hydrogen production results are compared in order to determine the ...

MHR-T power-technological complex: safety aspects
The paper deals with the safety assurance aspects of a power-technological complex for large-scale hydrogen production (MHR-T PTC) combining the innovative nuclear and hydrogen processes. It reviews practical realisation of the nuclear-hydrogen concept developed in early 1970s on the basis of high-temperature helium reactor plants of the fourth MHR-T generation, which allows production of ...

Effect of pH control strategies and substrate concentration on the hydrogen yield from fermentative hydrogen production in large laboratory-scale
A series of batch experiments investigating two different pH control strategies, initial pH adjustment and continuous pH control, have been carried out in large laboratory-scale reactors with working volumes of 30 L. In both cases, pH was varied between 5 and 7.5. Sucrose concentrations were also varied starting from 0 up to 30 g/L. Higher hydrogen production yields can be achieved by batch ...

The possibilities for hydrogen production from H2S and storage in the Black Sea
The Black Sea, a highly isolated inland sea, is the largest anoxic zone in the world. Since the hydrogen sulphide (H2S) zone was discovered in the early 19th century in the Black Sea, it has been accepted that there is no life in the depths of the Black Sea and only bacteria live in the H2S layer. A high content of organic matter, with maximum processes of bacterial sulphate reduction, is the ...

Hydrogen Market in APAC
Hydrogen as a clean and green energy resource has attracted extensive attention to hydrogen research and application worldwide. Recently, APAC’s countries, like Australia, Japan, Korea, China, have issued some new policies to support hydrogen development, and even some of those put the development of hydrogen energy at a strategic level. This report mainly introduces the development and ...

Concurrent photocatalytic hydrogen production and organic degradation by a composite catalyst film in a two-chamber photo-reactor
A novel visible light-driven photocatalyst film, MoS2/Ag/TiO2, was synthesized on a glass-fiber membrane. The composite catalyst film had a multi-layer structure with Ag as nanoconjunctions between the MoS2 and TiO2 layers. The catalyst film performed well for both photocatalytic hydrogen production and organic degradation in a two-chamber photo-reactor under either solar or visible light. ...

The public perception of hydrogen and nuclear technologies
Nuclear is the most likely candidate to produce the energy needed for the 21st century. However, the existing negative perception of nuclear power production by most of the population is a problem that hampers the successful development of both nuclear energy and new technologies such as hydrogen energy. Insufficient nuclear erudition is the main reason for distrust of modern nuclear hydrogen ...

Evaluation of low-cost cathode catalysts for high yield biohydrogen production in microbial electrolysis cell
As an ideal fuel due to the advantages of no pollution, high combustion heat and abundant sources, hydrogen gas can be produced from organic matter through the electrohydrogenesis process in microbial electrolysis cells. But in many MECs, platinum is often used as catalyst, which limits the practical applications of MECs. To reduce the cost of the MECs, Ni-based alloy cathodes were developed by ...

Dynamical safety assessment of hydrogen production nuclear power plants using system dynamics method
Nuclear power plants for hydrogen production are investigated in the aspect of nuclear safety. The non–linear dynamical safety assessment is introduced for the analysis of the high temperature gas cooled reactor (HTGR) which is used for hydrogen production as well as electricity generation. The dynamical algorithm is adjusted for the safety assessment with an easier and reliable output. A ...

Coupling a hydrogen production process to a nuclear reactor
Work is currently underway to define a pre-conceptual design of a hydrogen production plant. The reference case is a VHTR dedicated to hydrogen production using the sulphur-iodine process. The chemical part of the plant is based on a very detailed flow-sheet where all components are listed. Considering the volume and flow-rates of the circulating products, a detailed image of the chemical plant ...

The sulphur–iodine and other thermochemical process studies at CEA
The thermochemical sulphur–iodine process is studied by CEA with the objective of massive hydrogen production using the heat coming from a high temperature reactor. A two-fold programme was set up in 2000. The main part is devoted to the study of the basic process, including optimisation of a detailed flow-sheet, thermodynamics measurements and industrial plant evaluation. In parallel, an ...

Potential applications of amorphous/metallic glassy alloys as hydrogen-permeable membranes for hydrogen production and bipolar plates for PEFC
The potential of amorphous/metallic glassy alloys as hydrogen-permeable membranes for hydrogen production and as bipolar plates for Polymer Electrolyte Fuel Cells (PEFCs) was investigated in this paper. Firstly, the hydrogen permeation of the melt-spun (Ni0.6Nb0.4)70Zr30-xTax (x = 5, 10, 15, 20 at%) alloys was measured. As a result, it was found that the hydrogen permeability of the alloys ...
