Making Hydrogen Abundant and Inexpensive

The quandary in producing and using hydrogen is that it’s the most common element in the universe and the oldest, having been formed within a micro-second of the Big Bang.  Despite that, it’s always associated with other materials, and to use pure hydrogen usually requires extracting from the material in which it’s found.  Water is the most common source for hydrogen, but as noted before, getting hydrogen out of water is harder than it looks. As shown in earlier blog, various techniques have been tried to make this extraction, some seemingly close to providing usable quantities at reasonable prices.  Dr. Daniel Nocera of MIT and later Harvard used a two-catalyst system to pull oxygen and hydrogen from water.

Salt Plus Titanium Dioxide Plus Light Equals Hydrogen

Microorganisms found in salt flats could offer a new path to green hydrogen fuel, according to researchers at the U.S. Department of Energy’s Argonne National Laboratory. Argonne researchers say that some desert salt flats shelter “a protein found in the membranes of ancient microorganisms,” and could hold promise for generating hydrogen fuel in an “environmentally friendly” way. Salts come in a variety of colors, and each edible variety can lend a unique taste to recipes, but the purple salt used in the Argonne experiments can help make hydrogen.

She develops her own research programs and works with users in the Center for Nanoscale …
