New Way to Make Hydrogen

zymano writes "Hydrogen is expensive to make and difficult to store. The most common way in making hydrogen is electrolyzing pure water. A new startup is trying a new way to make hydrogen. The process uses sodium which industry shuns because it generates sparks and heat when mixed with water. Signa has devised a way to mix sodium with silica gel or crystalline silicon to create a powder that essentially strips electrons from the sodium molecules in advance and stores them. When water is introduced, the chemical reaction proceeds calmly. The powder generates hydrogen efficiently. More than 9 percent of a kilogram of the powder gets converted to hydrogen and little energy is lost through heat."

    Maybe they could find a way to use sodium and silica to make LSD! That'd be a real hoot!
