Then, collect their water emissions and start the procedure again. One look at the list of ingredients in today's fuel cells, however, shows that this ideal isn't yet being followed. Because processes that use sunlight to extract hydrogen remain costly and inefficient, fossil fuels still supply the hydrogen in most fuel cells. Hoping to break the fossil fuel habit, a team of Israeli, German, and Japanese scientists has created a device that boosts the efficiency of solar-powered hydrogen extraction by 50 percent. The group placed a photovoltaic cell on top of two flat, finger-long electrodes. The combination "is very efficient in converting solar energy [into an electric current] but also provides nearly the ideal voltage for splitting water" into hydrogen and oxygen, says team leader Stuart Licht of the Technion in Haifa, Israel. A water molecule splits, or undergoes electrolysis, at only 1.23 volts. Licht and his colleagues describe their device in the Sept. 28

12. HYDROGEN ENERGY SYSTEM: hydrogen energy SYSTEM The results indicate that the solar hydrogen energy system is the best energy system to ascertain a sustainable future. http://www.iahe.org/Hydrogen_energy_system.htm

HYDROGEN ENERGY SYSTEM: A PERMANENT SOLUTION TO GLOBAL PROBLEMS T. Nejat Veziroglu Clean Energy Research Institute University of Miami, Coral Gables, FL 33124, USA Summary: However, there are other energy systems proposed for the post-petroleum era, such as a synthetic fossil fuel system. In this system, synthetic gasoline and synthetic natural gas will be produced using abundant deposits of coal. In a way, this will ensure the continuation of the present fossil fuel system. The two possible energy systems for the post-fossil fuel era (i.e., solar hydrogen energy system and synthetic fossil fuel system) are compared with the present fossil fuel system by taking into consideration production costs, environmental damages and utilization efficiencies. The results indicate that the solar hydrogen energy system is the best energy system to ascertain a sustainable future. The paper is presented in a question/answer format. Question 1: What are the energy related global problems: Answer 1: Fossil fuels, which fed this amazing economic growth, were the medicine to cure deprivation. But it was an untested medicine at that. As planet Earth consumed more and more fossil fuels, two important predicaments started to emerge: (1) the fossil fuels would be depleted in a foreseeable future, and (2) the fossil fuels and their combustion products were causing global environmental problems.

Hydrogen is also found in many organic compounds, notably the hydrocarbons that make up many of our fuels, such as gasoline, natural gas, methanol, and propane. reforming . Currently, most hydrogen is made this way from natural gas. An electrical current can also be used to separate water into its components of oxygen and hydrogen. This process is known as electrolysis . Some algae and bacteria, using sunlight as their energy source, even give off hydrogen under certain conditions. A fuel cell combines hydrogen and oxygen to produce electricity, heat, and water. Fuel cells are often compared to batteries. Both convert the energy produced by a chemical reaction into usable electric power. However, the fuel cell will produce electricity as long as fuel (hydrogen) is supplied, never losing its charge. Fuel cells are a promising technology for use as a source of heat and electricity for buildings, and as an electrical power source for electric motors propelling vehicles. Fuel cells operate best on pure hydrogen. But fuels like natural gas, methanol, or even gasoline can be reformed to produce the hydrogen required for fuel cells. Some fuel cells even can be fueled directly with methanol, without using a reformer. In the future, hydrogen could also join electricity as an important energy carrier. An energy carrier moves and delivers energy in a usable form to consumers. Renewable energy sources, like the sun and wind, can't produce energy all the time. But they could, for example, produce electric energy and hydrogen, which can be stored until it's needed. Hydrogen can also be transported (like electricity) to locations where it is needed.

15. Solar Hydrogen Energy Corporation Shec has developed a process to produce hydrogen which does not create green house gases such as co or co2, using only water and sunlight as the inputs into the process. http://www.solar-h2.com/

Clean Renewable Energy for the 21st Century and Beyond (TM) Solar Hydrogen Energy Corporation (SHEC) (TM) Visit our new commercial site at: www.shec-labs.com Mission Statement SHEC's mission is to provide to the world a source of clean renewable energy for the 21st century and beyond. Background Traditional methods of producing hydrogen have been to convert fossil fuels to hydrogen. This process creates extensive greenhouse gases in the conversion process, and has little benefit over burning the fossil fuels directly. The Product: SHEC has developed a process to produce hydrogen which does not create green house gases such as CO or CO2. It is "100% clean and 100% renewable" (TM). We use only water and sunlight as our only inputs into our proprietary process. The energy cycle is much like the oxygen cycle of plants and animals. Animals use oxygen, and give off CO2. Plants on the other hand use CO2 and give off Oxygen. The hydrogen energy cycle is very similar. Our process takes water and produces Hydrogen and Oxygen. The oxygen can be released to the atmosphere (or bottled and sold), while the hydrogen is used as fuel. When the hydrogen is burned, it takes oxygen from the atmosphere and creates heat, with its by-product being water. The Market: Other Benefits: An area less than the size of North Dakota, has enough solar radiation to supply the entire energy needs of the United States. Reliance on imports of fossil fuels will be eliminated, and so will the cost of wars associated with it. The health benefits and preservation of our planet is of primary importance. Pollution of our atmosphere from the continual burning of fossil fuels have costs which are overlooked. These include health costs of respiratory related diseases caused by polluted air, and eventual costs of crop failures due to global warming.
