Researchers at the University of California at Berkeley have engineered a strain of pond scum that could, with further refinements, produce vast amounts of hydrogen through photosynthesis.
Hundreds of semitrailer trucks zipping along North American highways are now powered in part by hydrogen. These 18-wheelers make hydrogen as they go using a system called Hydrogen Fuel Injection which eliminates the need for high-pressure, cryogenic storage tanks or hydrogen filling stations.
Two scientists say they have come up with a way to make hydrogen fuel cheap enough to compete with gasoline, by combining nuclear and wind power.
Solar power these days comes from cells that turn light into electricity, but researchers are now working on materials that can crank out hydrogen.
Virginia Polytechnic and State University researchers have developed a large molecule, or supramolecular complex, capable of using sunlight to separate hydrogen from water. The complex could be used to produce hydrogen for clean-burning combustion engines and fuel cells.
Researchers at a government nuclear laboratory and a ceramics company in Salt Lake City say they have found a way to produce pure hydrogen with far less energy than other methods, raising the possibility of using nuclear power to indirectly wean the transportation system from its dependence on oil.
A new "solar hydrogen" method could produce cheap hydrogen from water in seven years, using a commercial solar panel.
An experimental generator that turns sunflower oil into hydrogen has been developed that can safely and efficiently produce fuel for everything from automobiles to homes.
The author looks at the potential of hydrogen fuel cells to not only "transform the future energy needs of the United States and the US Air Force, but also to change how and why we fight."
Researchers have discovered an ethanol-based process that could leap several of the hurdles facing the hydrogen economy: the high cost of making hydrogen, the impact on global warming of burning hydrogen, and the safe and efficient use of hydrogen in cars.
