For more than a decade, hydrogen has been touted as a clean alternative to fossil fuels because it releases a significant amount of energy relative to its weight and also produces nothing but water when it burns. It can also be produced cleanly, using biological methods, such as photosynthesis. However, the high costs incurred in production have proved too big an obstacle to allow for its wide-spread use.
