Domestic hydrogen production by an integrated biomass gasification/sponge iron process
The share of hydrogen in the energy market is increasing with the implementation of fuel cell systems and the growing demand for zero-emission fuels. One major challenge is a distribution system for hydrogen. This drawback [...]
An Assessment of Renewable Hydrogen Costs, Infrastucture, and Resource Constraints
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
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
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 [...]
Structural Stability of Hydrogen Storage Materials
Elastic instability by hydrogenation and hydrogen diffusion are studied by molecular dynamics method. The bulk modulus instability causes the anorphization by hydrogenation. The atomic relaxation reduces the pressure fluctuation terms i n the elastic constant, [...]
Computer Simulation of Hydrogen Storage Materials
We develope a new software to design the hydrogen storage materials. The energetic and dynamical behavior of the materials are studied. As an example, we illustrate the amorphization process of intermetallics by hydrogenation, i.e. hydrogen [...]
New Catalytic system for Producing Pure Hydrogen -Water-gas-shift Reaction of Supported Copper Catalysts-
The catalytic activity of water-gas-shift (WGS) reaction was investigated for alumina-supported copper and copper-iron oxides catalysts calcined at different temperatures. Alumina-supported copper catalysts calcined at 1073 K, followed by the treatment in H2 at 523 [...]
Development of Efficient, Compact and Environmentally Friendly Hydrocarbon Reformer for the Production of Pure Hydrogen
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
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 [...]
