Bimetallic Nanoparticles for Advanced Energy Conversion Technologies

Sims C.M., Eichhorn B.W., University of Maryland, US

Proton exchange membrane fuel cells (PEMFC) are highly regarded as a clean alternative energy technology for motor vehicles, power generators, etc. One factor hindering their commercial viability is the poisoning of the hydrogen oxidation reaction [...]

Renewables-source Hydrogen Systems: Alternatives to Electricity for Transmission, Storage, and Integration

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 [...]

Gasification Technology Developed for the Production of Renewable Hydrogen

Dodd D.M., Hazard J., Sierra Energy, US

Hydrogen fuels from renewable sources are considered some of the most promising alternative fuels for reducing oil consumption, greenhouse gas emissions, and air pollution. Sierra Energy’s FastOx technology is a ﬁxed-bed gasification system that breaks [...]

Catalytic Performance Enhancement by Low Temperature Plasma Treatment

Miley G.H., Srivastava S.N., Chen G., UiUC/NPL Associates, US

Polymer Electrolyte Membrane (PEM) fuel cell electrocatalysts are composed of noble metals (e.g. platinum), which are scarce and expensive. A simple plasma-surface modification method is described to increase the performance of PEM fuel cell catalytic [...]
