How does hydrogen metallize?
July 29, 2013 — Hydrogen is deceptively simple. It has only a single electron per atom, but it powers the sun and forms the majority of the observed universe. As such, it is naturally exposed to the entire range of pressures and temperatures available in the whole cosmos. But researchers are still struggling to understand even basic aspects of its various forms under high-pressure conditions.

Low-cost nanosheet catalyst discovered to split hydrogen from water

Low-cost nanosheet catalyst discovered to split hydrogen from water  Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have developed a new electrocatalyst that addresses one of these problems by generating hydrogen gas from water cleanly and with much more affordable materials. The novel form of catalytic nickel-molybdenum-nitride -- described in a paper published online May 8, 2012 in the journal Angewandte Chemie International Edition -- surprised scientists with its high-performing nanosheet structure, introducing a new model for effective hydrogen catalysis.

Researchers create more efficient hydrogen fuel cells

Researchers create more efficient hydrogen fuel cells  "We are very encouraged by our first attempts that suggest that we can create two cost-effective and highly active palladium- and gold-based catalysts -for hydrogen fuel cells, a clean and renewable energy source," Stolbov said.

A basic -- and slightly acidic -- solution for hydrogen storage

A basic -- and slightly acidic -- solution for hydrogen storage   ScienceDaily (Mar. 20, 2012) — Sometimes, solutions for hard problems can turn out to be pretty basic. That's especially true for a team of researchers at the Office of Science's Brookhaven National Laboratory (Brookhaven Lab), where the solution for a hard problem they were working on turned out to be pretty basic…and also a bit acidic.

Hydrogen: A Dream or Delusion? : Greentech Media Hydrogen.

In green technology circles, just mentioning the word is enough to start an argument.

Hydrogen could become a ubiquitous source of electricity and heat, say advocates. Plus, it’s somewhat prevalent. Hydrogen remains the most abundant element in the universe and every molecule of water contains two atoms of hydrogen.

Breakthrough in nanocomposite for high-capacity hydrogen storage

Breakthrough in nanocomposite for high-capacity hydrogen storage: "Now, scientists with the U.S. Department of Energy (DOE) Lawrence Berkeley National Laboratory (Berkeley Lab) have designed a new composite material for hydrogen storage consisting of nanoparticles of magnesium metal sprinkled through a matrix of polymethyl methacrylate, a polymer related to Plexiglas. This pliable nanocomposite rapidly absorbs and releases hydrogen at modest temperatures without oxidizing the metal after cycling -- a major breakthrough in materials design for hydrogen storage, batteries and fuel cells."
