'Artificial leaf' makes hydrogen from solar cell | Green Tech. Drawing from nature, Massachusetts Institute of Technology professor Daniel Nocera thinks he can draw cheap and clean energy from water. At the National Meeting of the American Chemical Society, Nocera yesterday presented results from research on making an "artificial leaf" to split water to get hydrogen fuel and oxygen. The goal is to use the solar cell to make hydrogen, which would be stored and then used in a fuel cell to make electricity. "The artificial leaf shows particular promise as an inexpensive source of electricity for homes of the poor in developing countries. Our goal is to make each home its own power station," Nocera said in a statement. In 2009, Nocera and others created Sun Catalytix to commercialize his work on relatively cheap catalysts made from nickel and cobalt for a device called an electrolyzer that splits water into hydrogen and oxygen.
Until now, research yielded very low efficiencies in converting sunlight to hydrogen using a solar cell. Solar generator splits water to make hydrogen | Green Tech. BOSTON--One of the barriers to the long-hoped-for hydrogen economy is a non-polluting energy source for hydrogen. Nanoptek is one company that's tapping the sun's energy. The Maynard, Mass., company this week said it is taking orders for a commercial solar hydrogen generator, which is now in pilot production. The company showed a smaller version of its product at the TechConnect conference here. Nanoptek envisions creating a system for storing energy from solar at large scale, making hydrogen for vehicles, and even home fueling.
In the nearer term, though, the company is seeking to sell solar generators to businesses that now buy tanks of hydrogen for industrial use. The company's product, called the Solar Hydrogen Generator 300, is slightly bigger than a typical solar photovoltaic panel, measuring two meters wide and one meter high. Its photocatalyst material is a titanium dioxide that's baked onto strips of titanium metal, which is "stressed" with a nanostructure before coating. A hybrid solar panel to make hydrogen | Green Tech. The best use of the sun's energy is to make hydrogen, according to a Duke University researcher. Engineer Nico Hotz earlier this week detailed results from his research around a rooftop solar panel that generates hydrogen from the sun's heat.
The hydrogen gas--which is made by breaking off hydrogen atoms from a water solution--can be stored and used to make electricity in a fuel cell. In his experiment, Hotz determined that his system creates more usable energy than solar photovoltaic panels which convert sunlight directly into electricity. He calculated the cost could be lower, too. There have been research efforts--and a commercial product from a company called Nanoptek --to make hydrogen from sunlight. Hotz's system, though, uses a new technique that relies on methanol, also known as wood alcohol, and a nano-engineered catalyst. Under the glass of Hotz's solar collector are copper tubes, coated with aluminum and aluminum oxide, which carry water and methanol.
Hydrogen and Fuel Cells Research - Hydrogen Production and Delivery. Most of the hydrogen in the United States is produced by steam reforming of natural gas. For the near term, this production method will continue to dominate. Researchers at NREL are developing advanced processes to produce hydrogen economically from sustainable resources. NREL's hydrogen production and delivery R&D efforts, which are led by Huyen Dinh, focus on the following topics: Biological Water Splitting Certain photosynthetic microbes use light energy to produce hydrogen from water as part of their metabolic processes.

Solar panels are becoming every more popular with home owners because they not only produce energy for free (in the long term), but any additional energy you don’t use can be sold to power companies. However, Japanese company FC-R&D has come up with a way of retaining that additional energy so as to power a home through the night or during an extended power outage.
The company’s new energy system is called ZEEP24, and it combines solar power, water and hydrogen to create a self-sufficient energy generating unit. During the day the solar panels produce energy and provide power for the house. Any additional energy is then used to produce hydrogen through the electrolysis of water. That hydrogen is then stored in an alloy which does not discharge any of the hydrogen, meaning it is available to use when required–there is no degradation like with batteries. The ZEEP24 is capable of storing 1,500 litres of hydrogen at full capacity, which translates to around 5kWh of electricity.

In this report we describe the status of our work with a solar water dissociation gas phase reactor: Solar radiant energy was concentrated by a parabolic mirror to produce high temperatures on a nozzle inside a solar reactor fed with water vapor (steam) at low pressure, to produce hydrogen and oxygen. A ceramic dissociator-nozzle was used as the target (absorber) for the concentrated solar-beam image. A sustainable, non-polluting energy currency is required to provide for human needs such as cooking, heating, transportation, electricity production, and refrigeration. At high temperatures, above about 1800 K, water vapor (steam) begins to dissociate into a mixture of H2, O2, H2O, O, H and OH.
E + H2O => H- + OH. h2_tech_roadmap. Hydrogen fuel tech gets boost from low-cost, efficient catalyst. May 3, 2011 — Scientists have engineered a cheap, abundant alternative to the expensive platinum catalyst and coupled it with a light-absorbing electrode to make hydrogen fuel from sunlight and water. The discovery is an important development in the worldwide effort to mimic the way plants make fuel from sunlight, a key step in creating a green energy economy. It was reported in Nature Materials by theorist Jens Nørskov of the Department of Energy's SLAC National Accelerator Laboratory and Stanford University and a team of colleagues led by Ib Chorkendorff and Søren Dahl at the Technical University of Denmark (DTU). Hydrogen is an energy dense and clean fuel, which upon combustion releases only water.
Today, most hydrogen is produced from natural gas which results in large CO 2 -emissions. Progress has so far been limited in part by a lack of cheap catalysts that can speed up the generation of hydrogen and oxygen. The team first tackled the hydrogen half of the problem. Story Source: Chance discovery may revolutionize hydrogen production. Producing hydrogen in a sustainable way is a challenge and production cost has so far proven to be too high. Now a team led by EPFL Professor Xile Hu has discovered that a molybdenum based catalyst is produced at room temperature, inexpensive and efficient. The results of the research are published online in Chemical Science. An international patent based on this discovery has just been filled. Existing in large quantities on Earth, water is composed of hydrogen and oxygen. It can be broken down by applying an electrical current; this is the process known as electrolysis. To improve this particularly slow reaction, platinum is generally used as a catalyst.
However, platinum is a particularly expensive material that has tripled in price over the last decade. Industrial prospects The new catalysts exhibit many advantageous technical characteristics. It's only by chance that Daniel Merki, Stéphane Fierro, Heron Vrubel and Xile Hu made this discovery during an electrochemical experience. Clean, cheap hydrogen production from water using cobalt catalyst. For years, proponents of the hydrogen economy have argued that hydrogen will replace traditional hydrocarbon fuels for transportation purposes.
But, so far, a lack of new, inexpensive methods for hydrogen production and storage has impeded this goal. Over the last several years, an MIT professor has been pushing cobalt catalysts as a cheap replacement for the expensive metals typically used to split water. A paper in this week's Proceedings of the National Academies of Science describes the latest progress here: integrating the cobalt catalyst with a silicon solar cell to create a device that uses the sun to split water. Hydrogen is a desirable fuel, because when it is burned or otherwise consumed (as in a fuel cell), it only produces water, although combustion results in small amounts of nitrogen oxides as by-products.
