howdych Posted November 8, 2010 Share Posted November 8, 2010 Compared with the energy it takes to separate oxygen and hydrogen from water, how much energy is released when they recombine? Link to comment Share on other sites More sharing options...
UC Posted November 9, 2010 Share Posted November 9, 2010 The same exact amount. Except the process used to split the water in the first place is inefficient, so the energy "used" and the energy that actually goes into splitting the water are different numbers.
