Production of hydrogen from various feedstock options using non-thermal plasma catalyzed reforming

Frost L., Hartvigsen J., Elangovan E., Ceramatec Inc, US

Ceramatec has developed a method for reformation of various hydrocarbons using a non-thermal plasma system to catalyze the reformation process. The plasma provides the same type of catalytic activity as a solid catalyst but since [...]

Why Hydrogen?

Blanchet S., Nuvera Fuel Cells, US

Modern civilization has grown reliant on plentiful, cheap and convenient energy from fossil fuels. Now, the reality of climate change has compelled us to reconsider our current ways of producing and using energy. The standardization [...]

Hydrogen Adsorption on Isoreticular Metal-Organic Framework

Loera-Serna S., López-Sosa S., Universidad Autónoma Metropolitana, MX

Implement the use of hydrogen as an alternative energy source would reduce the use of fossil fuels, therefore it seeks to challenge any difficulty, mainly storage; an alternative of great interest is the use of [...]

Catalytic Decomposition of Methanol Effected by Cu-ZnO@C Nanoreactors

Hong C.-I., Peng C.-Y., Wei Y-L, Jou C.-J.G., Sun I.-W., Paul Wang H., National Cheng Kung University, TW

Decomposition of methanol (DM) to CO and H2 can be catalyzed by Cu-ZnO@C core-shell and Cu-ZnO○yC yolk-shell nanoreactors at 473-573 K. It is found that the reactivity of DM catalyzed by the nanoreactors increases with [...]

Nano-oxyhydride catalysts for hydrogen production from bioethanol at room temperature

Jalowiecki-Duhamel L., CNRS, FR

H2 economy could be clean and sustainable only if it is produced from renewable sources and bioethanol obtained through biomass is a promising renewable source of hydrogen. Well tuning the preparation, formulation and conditions applied, [...]

Renewables-source Energy Storage for < $1.00 / kWh Capex as Hydrogen and Ammonia C-free Fuel Systems

Leighty B., The Leighty Foundation, US

Electricity systems will be inadequate to humanity's urgent task of rebuilding its largest industry -- energy -- from ~85% fossil today to 100% renewable sources by Year 2100. To supply all energy, from all sources [...]

A hierarchical carbon nanofiber-In2S3 photocatalyst with well controlled nanostructures for highly efficient hydrogen production under visible light

Gao P., Li A., Liu Z., Tai M., Liu Z., Sun D.D., Nanyang Technological University, SG

Hydrogen as a renewable clean energy has attracted a lot attention because of its high heat conversion efficiency and zero carbon emission, while synthesizing highly efficient material for photocatalytic hydrogen production under solar light remains [...]

Hydrogen Generation from Thermochemical Water-Splitting Using Core Shell Ni-Ferrite/Y2O3 Nanoparticles

Amar V.S., Shende R.V., South Dakota School of Mines & Technology, US

During thermochemical water-splitting process for hydrogen generation,ferritenanoparticles undergo significant grain growth that reduces their surface area and affect the porous morphology. Consequently, hydrogen volume generation diminishes with increase in thermochemical cycles. In order to mitigate [...]

Synthesis of Visible light Nanocomposites for H2 Production

Hussein A.M., Shende R.V., South Dakota School of Mines & Technology, US

Visible light active nanocomposites were synthesized by the sol-gel method using non-ionic surfactant as a template. Cr-doped ZrO2-modified coupled ZnO/TiO2 composite was thoroughly characterized for surface area, crystal phase, microstructure, elemental identification and band gap [...]
