    Moscow — Leaders of Turkey and Russia signed a long-delayed deal Monday to build the TurkStream gas pipeline under the Black Sea to deliver Russian gas to Europe's doorstep within three years. The rapid warming trend in Russo-Turkish relations holds deep implications for Syria's immediate crisis, which dominated the talks and the subsequent headlines, but the fallout from that pipeline deal is a potentially crushing blow to struggling pro-Western Ukraine and may be rearranging strategic realities around the region for many years to come. Analysts say that if TurkStream goes ahead it will enable Moscow to cut its former main...

    Green Car Reports ^ | August 19, 2016 | Stephen Edelstein
    Hydrogen fuel-cell cars face an uphill battle toward mass adoption. Both cars and fueling infrastructure need to be made widely available before large numbers of consumers can seriously consider switching from gasoline to hydrogen. But under certain circumstances, hydrogen could prove very attractive to consumers for one simple reason. When produced using renewable energy, hydrogen could cost nearly the equivalent of 50-cent-per-gallon gasoline, according to a study by the National Renewable Energy Laboratory (NREL). That will only happen if "the stars align" and several factors work in hydrogen's favor, notes industry trade journal WardsAuto noted in a June report on...
  • Hydrogen for refineries is increasingly provided by industrial suppliers

    Energy Information Administration ^ | JANUARY 20, 2016 | Energy Information Administration
    Refineries use hydrogen to lower the sulfur content of diesel fuel. Refinery demand for hydrogen has increased as demand for diesel fuel has risen both domestically and internationally, and as sulfur-content regulations have become more stringent. EIA data show that much of the growth in hydrogen use at refineries is being met through hydrogen purchased from merchant suppliers rather than from increased hydrogen production on-site at the refinery. The increased use of purchased hydrogen has implications for the refining industry's use of natural gas as a feedstock. There are two forms of hydrogen production: on-purpose hydrogen production using steam methane...

    IEEE Spetrum ^ | 14 Dec 2015 | Charles Q. Choi
    Solar heat could help generate both electricity and hydrogen fuel at the same time in a system that scientists in Switzerland and the United States call "hydricity." Such a system could supply electricity round-the-clock with an overall efficiency better than many photovoltaic cells, researchers add. There are two ways solar energy is used to generate electricity. Photovoltaic cells directly convert sunlight to electricity, while solar thermal power plants--also known as concentrating solar power systems--focus sunlight with mirrors, heating water and producing high-pressure steam that drives turbines. Photovoltaic cells only absorb a portion of the solar spectrum, but they can generate...

    You expect a certain sort of magic from a car like Toyota's Mirai, the world's first mass-market, hydrogen-powered all-electric named after the Japanese word for "future." It maxes out at 300 miles, refuels in five minutes and spits out zero emissions except for water, all for tens of thousands of dollars less than Tesla's electric Model S. But behind the wheel of the four-door Mirai, which California drivers can buy in October for around $50,000, what you get is something much more, well, boring: a smooth, quiet, mid-size sedan you wouldn't find out of place in a school pick-up circle....

  • Hydrogen: the net-negative energy option

    To extract hydrogen from natural compounds such as water, methane, or coal requires very large inputs of energy. Most commonly, hydrogen is produced from methane gas using heat and steam, or by electrolysis of water using large quantities of electricity. Hydrogen can be used to power rockets, cars, and engines of all types. However, the energy used to produce the hydrogen can never be fully recovered from the energy in the hydrogen. It is thus not a source of energy. It is merely a storehouse for energy – a battery.

    In research out of the University of Manchester in the UK led by Nobel Laureate Andre Geim, it has been shown that the one-atom-thick materials graphene and hexagonal boron nitride (hBN), once thought to be impermeable, allow protons to pass through them. The result, the Manchester researchers believe, will be more efficient fuel cells and the simplification of the heretofore difficult process of separating hydrogen gas for use as fuel in fuel cells. This latest development alters the understanding of one of the key properties of graphene: that it is impermeable to all gases and liquids. Even an atom as...

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...

    Electric vehicles may seem like the inevitable evolution of the conventional gas-powered automobile, but not every carmaker agrees. Hyundai will sit out the pure-electric car round, and instead concentrate its efforts on designing the next-generation hydrogen fuel cell vehicle. As part of a decision by the Hyundai-Kia Automotive Group, Hyundai--which owns 51 percent of Kia--will stop all efforts to develop and produce electric vehicles, according to Korean newspaper The Chosun Iblo. The auto manufacturer previously planned to produce the all-electric BlueOn, but it has shelved those plans and instead will focus on developing the Tucson ix Fuel Cell Electric Vehicle....

    A grain of salt or two may be all that microbial electrolysis cells need to produce hydrogen from wastewater or organic byproducts, without adding carbon dioxide to the atmosphere or using grid electricity, according to Penn State engineers. "This system could produce hydrogen anyplace that there is wastewater near sea water," said Bruce E. Logan, Kappe Professor of Environmental Engineering. "It uses no grid electricity and is completely carbon neutral. It is an inexhaustible source of energy." Microbial electrolysis cells that produce hydrogen are the basis of this recent work, but previously, to produce hydrogen, the fuel cells required some...

    Hydrogen accumulates in pipes at Fukushima's No. 1 reactor September 24, 2011 By HIDENORI TSUBOYA / Staff Writer Hydrogen has accumulated to a level higher than previously thought in pipes connected to the No. 1 reactor containment vessel at the Fukushima No. 1 nuclear power plant, the plant's operator said Sept. 23. But Tokyo Electric Power Co. officials said an explosion was unlikely because nonflammable nitrogen was being pumped in to prevent oxygen from entering the containment vessel and triggering a blast. TEPCO also said the discovery of the hydrogen buildup will not affect the road map toward achieving a...
  • Breakthrough in hydrogen fuel cells: Chemists develop way to safely store, extract hydrogen

    A team of USC scientists has developed a robust, efficient method of using hydrogen as a fuel source. Hydrogen makes a great fuel because of it can easily be converted to electricity hydrogen is that, because it is a gas, it can only be stored in high pressure or cryogenic tanks. In a vehicle with a tank full of hydrogen, "if you got into a wreck, you'd have a problem," said Travis Williams, assistant professor of chemistry at the USC Dornsife College. A possible solution is to store hydrogen in a safe chemical form. Earlier this year, Williams and his...

    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
