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."

    Well, you combine it with oxygen to form water, and then ship it through a pipeline.... oh, nevermind...

  4. Why MAKE Hydrogen? by Anonymous Coward · · Score: 5, Funny

    Why do we need to make hydrogen? There's TONS of it sitting right out in the open, ripe for the taking!

    My fellow slashdotters, what we need only to do is MINE THE SUN!

    All we need is a space shuttle, and a team of roughneck oil workers. With a bit of training they will be SPACE MINERS, and we can send them on their merry way into the sun to mine it for us!

      (obligatory)

      And for all those naysayers who claim it can't be done because the sun is too hot - we'd only mine the sun AT NIGHT!
