The only good reason to extract hydrogen is for storage. For example, solar energy could be used to extract the hydrogen from urea, which could then be burned at night to continue to generate power.
On it's own, any technology that requires extraction of hydrogen will result in a net loss. Sometimes a HUGE net loss.

- davorak 14y agoI believe you are mistaken in this case. The technical paper, linked from the article, will explain better then I can: http://www.suttonfruit.com/pics/urea_electrolysis.pdf http://www.suttonfruit.com/pics/urea_electrolysis.pdf
