Electrolysis of water

  1. Oct 4, 2008 #1
    My question is: how much elctrical energy is required to separate 1 liter of water into hydrogen & Oxygen at sea leavel? I would like to see the method (equations) explained.

    Thank you,
    A Vowles

    work = current * voltage * time

    The first equation I'd use is the chemical equation for hydrogen electrolysis. The energy in it is the lower bound of what is required (it doesn't include any source of inefficiency). The bond energies are available via google.
