Army Research Lab discovers aluminum nanomaterial rapidly splits water on contact

Green Car Congress

Researchers at the US Army Research Laboratory (ARL) have discovered that a nano-galvanic aluminum-based powder of their design splits water on contact, producing hydrogen and oxygen. The team demonstrated a small radio-controlled tank powered by the powder/water reaction. —Scott Grendahl, a materials engineer and team leader.

Researchers Develop New Lower-Cost, Efficient Catalyst for Water Gas Shift Reaction for Hydrogen Production

Green Car Congress

A team of researchers from Tufts University, the University of Wisconsin-Madison and Harvard University report that alkali ions (sodium or potassium) added in small amounts activate platinum adsorbed on alumina or silica for the low-temperature water-gas shift (WGS) reaction (H 2 O+CO→ H 2 +CO 2 ) used for producing hydrogen.

Researchers devise seawater-resilient bipolar membrane electrolyzer for turning seawater into hydrogen

Green Car Congress

Generation of H 2 and O 2 from untreated water sources represents a promising alternative to ultrapure water required in contemporary proton exchange membrane-based electrolysis. The results of their study, published in Joule , could help advance efforts to produce low-carbon fuels.

ARPA-E awards $38M to 12 projects leading used nuclear fuel recycling initiative

Green Car Congress

The US Department of Energy’s (DOE’s) Advanced Research Projects Agency - Energy (ARPA-E) will award $38 million to 12 projects that will work to reduce the impacts of light-water reactor used nuclear fuel (UNF) disposal. Upon discharge from a nuclear reactor, the UNF is initially stored in steel-lined concrete pools surrounded by water.

New oxygenate additive for diesel fuels from glycerol

Green Car Congress

Researchers from Tatung and National Cheng Kung Universities in China, and Case Western Reserve University in Ohio, report manufacturing a new oxygenate additive for diesels (bio or petroleum) using glycerol (a major byproduct of biodiesel production), dimethyl sulfate (DMS), and sodium hydroxide pellets as raw materials.

New mesoporous crystalline Si exhibits increased rate of H2 production; potential use in Li-ion batteries also

Green Car Congress

The nanosized crystalline primary particles and high surface areas enable an increased rate of photocatalytic hydrogen production from water and extended working life. The etching process uses to produce porous silicon results in the loss of material, said said Donghai Wang, assistant professor of mechanical engineering, who led the research.
