| Hydrogen gas offers one of the most promising sustainable energy alternatives to limited fossil fuels. But traditional methods of producing pure hydrogen face significant challenges in unlocking its full potential, either by releasing harmful carbon dioxide into the atmosphere or requiring rare and expensive chemical elements such as platinum. Now, 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,... |

| Squeezing hydrogen at extreme pressures changes it into a mix of honeycombed atoms layered with free-floating molecules — an entirely new state of the element and the first new phase found in decades. If confirmed, the discovery will be only the fourth known phase of hydrogen, the simplest element and one long probed for basic insights into the nature of matter. “I think we have pretty bulletproof evidence that there is a new phase,” says Eugene Gregoryanz of the University of Edinburgh, leader of the team that will report the work in an upcoming Physical Review Letters.

| Edward Teller, the father of the hydrogen bomb, had a thing for nuclear bombs. He wanted them bigger, smaller, faster, used in ways that no one had thought of before or since, and always more of them. He suffered no fools, and though he would be more villified than any other American scientist in the 20th century, he always dismissed his critics as lacking in common sense or patriotism. Amid Cold War paranoia and fears of the Soviet nuclear program, the stakes were simply too high: for the free world, building the most powerful weapon in history was a matter... |

| Researchers led by MIT professor Daniel Nocera have produced something they’re calling an “artificial leaf”: Like living leaves, the device can turn the energy of sunlight directly into a chemical fuel that can be stored and used later as an energy source. The artificial leaf — a silicon solar cell with different catalytic materials bonded onto its two sides — needs no external wires or control circuits to operate. Simply placed in a container of water and exposed to sunlight, it quickly begins to generate streams of bubbles: oxygen bubbles from one side and hydrogen bubbles from the other. If... |

| While roofs across the world sport photovoltaic solar panels to convert sunlight into electricity, a Duke University engineer believes a novel hybrid system can wring even more useful energy out of the sun's rays. Instead of systems based on standard solar panels, Duke engineer Nico Hotz proposes a hybrid option in which sunlight heats a combination of water and methanol in a maze of glass tubes on a rooftop. After two catalytic reactions, the system produces hydrogen much more efficiently than current technology without significant impurities. The resulting hydrogen can be stored and used on demand in fuel cells. For... |

The aviation industry should focus research and development programmes on liquid hydrogen rather than third-generation biofuels in the quest to reduce carbon dioxide emissions, according to World Wildlife Fund director for global energy policy Stephan Singer. Speaking at a roundtable on environmental issues at the European Parliament in Brussels today - part of the Aerospace and Defence Industries Association of Europe's (ASD) Aeroweek conference - Singer said liquid hydrogen and algae-derived biofuels should be the focus of investment over other alternative fuels because they are less likely to interfere with land used for food producti
