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 [...]

Tuning of Nafion® by HKUST-1 as coordination network to Enhance Proton Conductivity for Fuel Cell Applications

Kim H.-J., Talukdar K., Choi S-J, Kyungpook National University, KR

MOFs have highly ordered structures and modular nature that can serve as a scaffold to anchor acidic groups and improve efficient proton transfer pathways. HKUST-1, a MOF material containing CuII–paddle wheel type nodes and 1,3,5-benzenetricarboxylate [...]

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 [...]

Electrocatalytic activity of core-shell carbon-metal nanocomposites derived from carbon dioxide

Lee J.W., Zhang J., Kim Y., Byeon A., Korea Advanced Institute of Science and Technology, KR

The polymer electrolyte fuel cells(PEFCs) have demonstrated one of promising devices to convert chemical energy of fuels with high energy efficiency, high power density, and low environment impact. Despite wide applications in many areas, the [...]

Hydrothermal synthesis of uniform porous carbon nanospheres and their gas storage capacity

Lee M.K., Nam S.W., Han J.S., Kang S., Seoul National University, KR

Highly porous nano carbon materials have been widely developed due to their advanced physical characteristics such as morphology, light weight, but more interestingly the possibility of designing the level of porosity as well as the [...]

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 [...]

Degradation Mechanisms in Electric Double Layer Capacitors Subjected to Voltage and Temperature Stress Testing

Peter A.S., Azarian M.H., Pecht M., University of Maryland, US

Due to their high power densities, electric double layer capacitors ¬¬(EDLCs) are used to supplement high energy density power sources (such as lithium ion batteries and fuel cells) in applications such as automotive kinetic energy [...]

Cluster-assembled carbon thin films and nanocomposites for electrochemical energy storage

Bettini L.G., Milani P., Piseri P., University of Milano, IT

Power generation and storage for microelectromechanical systems, miniaturized biomedical devices, sensors and integrated on-chip components, can significantly benefit from the fabrication and integration of planar thin film supercapacitors. Supersonic cluster beam deposition (SCBD) of nanostructured [...]
