Hydride | chemical compound | Britannica
Hydride, any of a class of chemical compounds in which hydrogen is coined with another element. Three basic types of hydrides—saline (ionic), metallic, and covalent—may be distinguished on the basis of type of chemical bond involved. A fourth type of hydride, dimeric hydride, may also be identified on the basis of structure (see borane).
FUEL FLEXIBLE GAS TURBINES AS ENABLERS FOR A LOW OR …
(Hydrogen generated from renewable sources is being called “green hydrogen”.) Electrolysis of water requires a large amount of energy, which could dramatically increase the cost of the hydrogen. A potential solution is available, in part, due to the fundamental
Hydrogen gas differs from natural gas in a nuer of significant ways, but none of these present insurmountable technical or economic obstacles to large -scale introduction. Hydrogen (H 2 ) is the smallest molecule on earth and by nature seeks to penetrate any other substance.
Fuel cells - For physics • For physicists • For all
Up to a few years ago, hydrogen fuel cells cost around $1000 for every kilowatt of power they generated – or around $100,000 per car. There were various avenues of research into how to bring the cost down, including work at Lawrence Berkley Laboratories on replacing the platinum alyst with a platinum-nickel alloy that was 90 times more efficient.
