As touted as it is as the energy source of the future, hydrogen is difficult and expensive to produce. Researchers at North Carolina State University have developed a process to extract hydrogen from water that's twice as efficient as previous methods.
The process uses "defective" carbon nanotubes; their defect is that they are incomplete and therefore more reactive, pulling out hydrogen atoms.
This process is of interest because it doesn't require high temperatures, which has been a limitation to hydrogen production. The researchers note, however, that their work is early and that it could be years, if ever, before their process becomes commercially viable.
