The Solar Cells that Make Hydrogen Gas

Annika Tostengard — Wed, 05 Aug 2015 05:30:13 +0000

Exciting new research demonstrates that solar energy could be used create hydrogen fuel. At the Eindhoven University of Technology, researchers have unveiled a new solar cell prototype that can actually make gas from water by using the electricity from the solar cell to set off a chemical reaction. The team accomplished this feat by shaping the […]

The science of nanotechnology, specifically nanomaterials, has grown by leaps and bounds in the last decade, and scientists are discovering more material characteristics than they ever could have before, just examining macromaterials. For example, when silicon [Si] oxidizes with water [H2O], it gives off hydrogen gas [H2], leaving a layer of silicon dioxide [SiO2]. While […]

Since 2003, BMW's South Carolina manufacturing plant has been using landfill-originated methane to power more than half of its equipment - that's old news. The good news is BMW is seeking a way to transform that methane to hydrogen gas, for a cleaner production process.

New Aluminum Alloy Helps Generate Clean Water and Cheap Electricity

A new aluminum alloy could soon clean out water and at the same time generate electricity for afflicted areas. Purdue University researchers Jerry Woodall and Go Choi have been working on the alloy of aluminum, gallium, indium and tin that could split polluted or salt water into hydrogen and oxygen and then reunite them to generate electricity and pure water.

Going green is a direction every major car maker has to approach at some point. It's just that for Hyundai it's more of a "going blue" trend than it is green: its new hydrogen fuel concept vehicle presented on this week's Seoul auto show is called ÃƒÂ¢€Ã…â€œBlue2ÃƒÂ¢€ and it reads "Blue Squared."

A new type of container for hydrogen gas has been developed by a team of Lawrence Berkeley Lab researchers. The inventors say it can store much more hydrogen than older versions, like pressurized tanks or those storing the gas inside some kinds of metallic molecular chains.

NASA to Make Its Future Rocket Fuel From Water and Aluminum

Ovidiu Sandru — Fri, 09 Oct 2009 14:46:47 +0000

At first, I found it surprising, but when I did some research and had a second though about it, I learned that when NASA or any other space agency launches a space ship, it consumes about 773 tons of ammonium perchlorate, and releases some 230 tons of hydrochloric acid immediately after launch.

63% Efficient Solid Oxide Fuel Cell Developed by NGK

Ovidiu Sandru — Thu, 18 Jun 2009 05:03:41 +0000

Highly efficient hydrogen fuel cells are wanted due to the high price the existing ones have so far. So, being efficient means less money spent on them, and more market share for hydrogen. SOFCs (solid oxide fuel cell) are a type of hydrogen fuel cell that use solid (not liquid) electrolyte to do their job, while being much more efficient.
