Stanford University scientists have developed a low-cost, emissions-free device that uses an ordinary AAA battery to produce hydrogen by water electrolysis. Unlike other water splitters that use precious-metal catalysts, the electrodes in this device are made of inexpensive and abundant nickel and iron. Professor Hongjie Dai and colleagues have developed a cheap, emissions-free device that [...]

Rutgers researchers have developed a technology using carbon nanotubes in place of platinum to produce hydrogen. The technology could overcome platinum’s major cost barrier to making clean-burning hydrogen fuel. The new technology is a novel catalyst that performs almost as well as cost-prohibitive platinum for so-called electrolysis reactions, which use electric currents to split water [...]

Empa researchers have developed a photoelectrochemical cell made of cheap raw materials that recreates a moth’s eye to drastically increase its light collecting efficiency. World wide researchers are investigating solar cells using sunlight and water that imitate plant photosynthesis to create synthetic fuels such as hydrogen. The Empa cell is made of cheap raw materials [...]

Scientists at Ecole Polytechnique Fédérale de Lausanne (EPFL) have designed a solution for transforming hydrogen gas into a less flammable liquid fuel that can be safely stored and transported and then returned to the gas state. The new technology has another application – the technology could be used with atmospheric carbon dioxide to synthesize a [...]

According to Penn State mechanical engineers porous silicon manufactured in a bottom up procedure using solar energy can be used to generate hydrogen from water.  The team also sees applications for batteries, biosensors and optical electronics as outlets for the new material. Donghai Wang, assistant professor of mechanical engineering said, The surface area of this [...]
