Production of Renewable Solar Hydrogen using Semiconductor Metal oxides by Water Photoelectrolysis

Misra M., Mohapatra S.K., Mahajan V.K., Das P.P., Raja K.S., University of Nevada Reno, US

Semiconductor metal oxide catalysts are exploited as photoelectro catalyst to generate hydrogen by water photoelectrolysis. A special design is carried to to get high volume of hydrogen for longer time.

Renewable Hydrogen Production Around the Globe

Deason K., Smith A., SENTECH, Inc., US

Survey of demonstration projects involving renewably produced hydrogen around the world.

An Assessment of Renewable Hydrogen Costs, Infrastucture, and Resource Constraints

Lasher S., Marion M., Kromer M., Roth K., TIAX LLC, US

This study uses a hydrogen logistics model to determine the most economic renewable resources and infrastructure to supply hydrogen to demand centers across the U.S. The model minimizes the projected average price for renewable-hydrogen using [...]

Protective Sensor Coatings for High-Throughput Screening of Hydrogen-Producing Microbes

Pryce Lewis H., GVD Corporation, US

Microbe-based hydrogen production is a potentially cost-effective, non-polluting approach to the production of hydrogen. Research efforts are underway to identify, isolate, and enhance microbial strains which facilitate direct sunlight-to-hydrogen conversion. These efforts are hampered by [...]

Generating Hydrogen on Demand by Splitting Water with Al Rich Alloys

Woodall J.M., Ziebarth J., Allen J. Jeon C.R., Choi G., Purdue University, US

Our group has been pioneering the production of on-demand hydrogen using aluminum-gallium alloys to split water into hydrogen, heat, and alumina. Recently, we have found that we can split water on demand using solid alloys [...]

Development of Efficient, Compact and Environmentally Friendly Hydrocarbon Reformer for the Production of Pure Hydrogen

Ciocci R., Abu-Mahfouz I., Elnashaie S., Penn State University at Harrisburg, US

Hydrogen represents one of the most promising clean fuels for the future. Reforming of hydrocarbons (e.g. natural gas, gasoline, diesel, etc.) represents the most promising route for the production of hydrogen because it yields hydrogen [...]

Bifurcation Behavior of a Novel Auto-thermal Circulating Fluidized Bed (CFB) Membrane Reformer

Abu-Mahfouz I., Elnashaie S., Ciocci R., Penn State University at Harrisburg, US

Static Bifurcation (SB), which mostly exhibits itself as multiple steady states, is characteristic of a novel auto-thermal Circulating Fluidized Bed Membrane Steam Reformer (CFB_MSR) for hydrocarbons. The present paper focuses on the practical implications of [...]

Nanomaterials for Desulfurization & Hydrogen Generation

Venugopal G., Vylkov N., Unfried K., Sapp M., Hunt A., nGimat Co., US

Energy R&D is being driven by concerns about global warming and air pollution largely attributed to pollutants from the burning of fossil fuels. While long-term energy strategies may call for the complete replacement of petroleum-based [...]

Effects of Spin Coating Catalysts on Micro-Fuel Cells Efficiency

Lung T., Reissman T., Kirby B., Garcia E., Cornell University, US

Using spin coating as the catalyst application technique in order to receive an even distribution on the porous silicon PEM. With even distribution, resistivity is more consistent, which produces a better power output from the [...]

In-plane and through-plane electrochemical conductivity and fuel cell performance of thin-film YSZ electrolytes

Johnson A.C., Ramanathan S., Harvard University, US

Submicron electrolyte films are a key component of intermediate temperature solid oxide fuel cells. Several groups have reported size-dependent in-plane ionic conductivity in thin films of yttria-stabilized zirconia (YSZ) and gadolinia-doped ceria. Here we report [...]
