Visitors to this site will find me to be a general bummer when it comes to energy news, but I did find this latest bit somewhat encouraging. I will, of course, caveat the shit out of it, because that is my nature.

Scientists: Alloy will Revolutionize Energy by Generating Hydrogen on the Cheap
State-of-the-art hydrogen extraction from water ("water splitting"), as I understand it, involves significant (electrical) energy inputs and CO2 generation, rendering its production prohibitive as a sustainable energy source.
If these barriers could be overcome, it could be a game-changer. From the article:
Research funded by the U.S. Department of Energy has demonstrated how to "tweak" an inexpensive semiconductor material to generate hydrogen from water by using sunlight, a finding that could revolutionize the energy sector...
