SRT Group, Inc. (SRT), a leader in innovative energy processes involving halogens, has developed and patented an innovative electrical energy storage and hydrogen production system. The SRT system stores off-peak electricity and produces hydrogen via a novel natural gas/steam thermo-electrochemical process. The following economic analysis indicates that the system can provide on-peak electrical...

The abnormal Brfnsted slopes observed for nitroalkanes are interpreted as a variation in the work terms, which is caused by a variation in hydrogen bond strengths with the free energy for proton transfer, rather than as an anomaly in the proton-transfer stage itself.

DSBNþ, a conjugated oligoelectrolyte (COE), was added to microbial electrolysis cells (MECs) to improve hydrogen recovery. The volume of hydrogen gas recovered in a fedbatch cycle of mixed culture MECs increased by 126 compared to controls (no COE addition), mainly by preventing the loss of hydrogen to methane production. Performance in pure culture MECs fed with Geobacter sulfurreducens increa...

This paper provides an insight to the feasibility of adopting hydrogen as a key energy carrier and fuel source in the near future. It is shown that hydrogen has several advantages, as well as few drawbacks in using for the above purposes. The research shows that hydrogen will be a key player in storing energy that is wasted at generation stage in large-scale power grids by off-peak diversion to...

Hydrogen bonds profoundly influence the architecture and activity of biological macromolecules. Deep appreciation of hydrogen bond contributions to biomolecular function thus requires a detailed understanding of hydrogen bond structure and energetics and the relationship between these properties. Hydrogen bond formation energies (ΔGf) are enormously more favorable in aprotic solvents than in wa...

Hydrogen production has gained increasing attention as a potential energy carrier, which can utilize many forms of renewable energy, such as biomass, wind and direct solar power. It has increased its significance as fossil fuels are being used up at a high rate and energy security is of greater importance to the United States and many other countries. Furthermore, hydrogen production offers the...

The hydrolysis of sodium borohydride as a source of hydrogen gas is studied at different mole ratios of H+ to NaBH4. The sulfonated porous carbon (SPC) is used as a source of hydrogen ion and catalyst. It is found that the sulfonated porous carbon exhibits high activity for the hydrolysis of NaBH4 to generate hydrogen gas at room temperature in comparison to Amberlyst-15 and Nafion-NR50. The ki...
