Of course, we can get hydrogen from bacteria rather than more energy-intensive electrolysis or extraction from methane. But, these "breakthroughs" often turn out not to be what they are assumed. Note the comments at the bottom of this WorldChanging post explaining why the information provided is incomplete and why the process described may end up being quite costly indeed. Hydrogen as a fuel has a lot of advantages (and some very serious disadvantages), but getting it out of the environment at a reasonable energy cost remains a difficult hurdle.
