Just add water
March 27, 2009
Next week MIT will announce a new electrolyzer that is cheap, efficient, and works at room temperature. So just by using a little water, electricity can be stored as Hydrogen, to be converted back as needed using a fuel-cell.
This could make it radically simpler and cheaper to store electricity than it is now with batteries.
The missing piece of the puzzle then is a much cheaper fuel-cell.
