Making hydrogen fuel from water and visible light at 100 times higher efficiency | A big step closer to hydrogen as a practical fuel to power vehicles and electrical devices. [Hydrogen: http://futuristicnews.com/tag/hydrogen/]
Biological hydrogen production (Algae) - Wikipedia, the free encyclopedia
The best of two worlds: Solar hydrogen production breakthrough.When light hits the system, an electrical potential builds up. The metal oxide layer acts as a photo anode and is the site of oxygen formation. It is connected to the solar cell by way of a conducting bridge made of graphite (black). Since only the metal oxide layer is in contact with the electrolyte, the silicon solar cell remains safe from corrosion. A platinum spiral serves as the cathode where hydrogen is formed.
Faster, Better Hydrogen Production: University of Glasgow chemists, however, have announced in Science a methodology that they say could transform the production side . Currently, the major way to produce hydrogen is by reacting natural gas with high-temperature steam . As with coal gasification—another widely used technique—this doesn’t help wean the world off fossil fuels or stop the production of greenhouse gases.
