This initiative, supported by legislation in the Energy Policy Act of 2005 (EPACT 2005) and the Advanced Energy Initiative of 2006, aims to develop hydrogen, fuel cell and infrastructure technologies to make fuel-cell vehicles practical and cost-effective by 2020

Why are governments, private businesses and academic institutions collaborating to develop and produce them? Fuel cells generate electrical power quietly and efficiently, without pollution. Unlike power

that use fossil fuels, the by-products from an operating fuel cell are heat and water

Hydrogen Energy Hydrogen is the simplest element. An atom of hydrogen consists of only one proton and one electron. It's also the most plentiful element in the universe. Despite its simplicity and abundance, hydrogen doesn't occur naturally as a gas on the Earth - it's always combined with other elements. Water, for example, is a combination of hydrogen and oxygen (H2O).

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.

Fossil fuels—coal, oil, and natural gas—are America's primary source of energy, accounting for 85 percent of current US fuel use.

Many of the environmental problems our country faces today result from our fossil fuel dependence. These impacts include global warming, air quality deterioration, oil spills, and acid rain.

Over the last 150 years, burning fossil fuels has resulted in more than a 25 percent increase in the amount of carbon dioxide in our atmosphere.

The fuel cell is being considered as an eventual replacement for the internal combustion engine for cars, trucks and buses. Major car manufacturers have teamed up with fuel cell research centers or are doing their own development. There are plans for mass-producing cars running on fuel cells. Because of the low operating cost of the combustion engine, and some unresolved technical challenges of the fuel cell, however, experts predict that a large scale implementation of the fuel cell to power cars will not occur before 2015, or even 2020.

Most fuel cells are still handmade and are used for experimental purposes. Fuel cell promoters remind the public that the cost will come down once the cells are mass-produced and lower cost material are found. While an internal combustion engine requires an investment of $35 to $50 to produce one kilowatt (kW) of power, the equivalent cost in a fuel cells is still a whopping $3,000 to $7,500. The goal is a fuel cell that would cost equal or less than diesel engines.

Fuel Cost & Availability. Hydrogen is currently expensive to produce and is only available at a handful of locations, mostly in California. Vehicle Cost & Availability. Fuel cell vehicles are currently far too expensive for most consumers to afford, and they are only available to a few demonstration fleets.

Estimated cost of hydrogen per kilogram in a variety of scenarios With all of this in mind, here are the cost estimates per kilogram (which each include $1.25 for taxes): Hydrogen from natural gas (produced via steam reforming at fueling station) $4 – $5 per kilogram of hydrogen Hydrogen from natural gas (produced via steam reforming off-site and delivered by truck) $6 – $8 per kilogram of hydrogen Hydrogen from wind (via electrolysis) $8 – $10 per kilogram of hydrogen Hydrogen from nuclear (via electrolysis) $7.50 – $9.50 per kilogram of hydrogen Hydrogen from nuclear (via thermochemical cycles – assuming the technology works on a large scale) $6.50 – $8.50 per kilogram of hydrogen Hydrogen from solar (via electrolysis) $10 – $12 per kilogram of hydrogen Hydrogen from solar (via thermochemical cycles – assuming the technology works on a large scale) $7.50 – $9.50 per kilogram of hydrogen As mentioned above, a cost of hydrogen of $4 to $12 per kilogram is equivalent to gasoline at $1.60 to $4.80 per gallon.

Fuel cell system costs have decreased significantly over the past several years but are still nearly twice as high as those for internal combustion engines. Likewise, onboard hydrogen storage costs are currently $15–$18/kWh for high-pressure gaseous storage, while the commercialization target is $2/kWh. There is potential to reduce this cost using lower-cost carbon fiber tanks or materials-based storage technologies, such as metal hydrides.

FCVs will have to offer consumers a viable alternative, especially in terms of performance, durability, and cost, to survive in this ultra-competitive market.

Most fuel cells designed for use in vehicles produce less than 1.16 volts of electricity—far from enough to power a vehicle. Therefore, multiple cells must be assembled into a fuel cell stack.

The Earth is getting warmer because people are adding heat-trapping gases to the atmosphere, mainly by burning fossil fuels. These gases are called greenhouse gases. Warmer temperatures are causing other changes around the world, such as melting glaciers and stronger storms. These changes are happening because the Earth's air, water, and land are all linked to the climate

It development of technology have been well proven over the years of time. When the sun emit heat to warm of the Earth it would be unbearable without wind. Wind widely disperses the heat making it bearable for all living things to survive. Without wind nothing would exist, it would just like all the other planets uninhibited by human nature or any living things for that matter.

A wind turbine is a machine that transforms kinetic energy from the wind into mechanical energy.

Wind power was first used in ancient times with the sail boat.

Wind power in the United States is a branch of the energy industry, expanding quickly over the last several years. Construction of new wind power generation capacity in the fourth quarter of 2012 totaled 8,380 megawatts (MW) bringing the cumulative installed capacity to 60,007 MW.[1] This capacity is exceeded only by China.[2] For the 12 months until July 2013, the electricity produced from wind power in the United States amounted to 157.8 terawatt-hours, or 3.91% of all generated electrical energy.[3]

The cost varies too, from $1 to $20 a kilo. A gallon of gasoline has the same energy content as a kilo of hydrogen, but vehicles using the latter get two to three times higher mileage.

According to the American Wind Energy Association, the total U.S. production of wind power is around 25 gigawatts

  Fuel Cell Basics Through this website we are seeking historical materials relating to fuel cells. We have constructed the site to gather information from people already familiar with the technology–people such as inventors, researchers, manufacturers, electricians, and marketers. This Basics section presents a general overview of fuel cells for casual visitors. What is a fuel cell? How do fuel cells work? Why can’t I go out and buy a fuel cell? Different types of fuel cells.     What is a fuel cell? A fuel cell is a device that generates electricity by a chemical reaction. Every fuel cell has two electrodes, one positive and one negative, called, respectively, the anode and cathode. The reactions that produce electricity take place at the electrodes.

in general terms, hydrogen atoms enter a fuel cell at the anode where a chemical reaction strips them of their electrons. The hydrogen atoms are now “ionized,” and carry a positive electrical charge. The negatively charged electrons provide the current through wires to do work. If alternating current (AC) is needed, the DC output of the fuel cell must be routed through a conversion device called an inverter.

Oxygen enters the fuel cell at the cathode and, in some cell types (like the one illustrated above), it there combines with electrons returning from the electrical circuit and hydrogen ions that have traveled through the electrolyte from the anode. In other cell types the oxygen picks up electrons and then travels through the electrolyte to the anode, where it combines with hydrogen ions.

Hydrogen Hydrogen can be produced domestically through electrolysis (the process of splitting the hydrogen and oxygen particles apart in a water molecule). When used in automobiles, a hydrogen-powered car will emit only water vapor from its tailpipe. Hydrogen vehicles use fuel cells as their source of power, and currently this technology is too expensive for most consumers. If the costs of fuel cell technology and hydrogen production can decrease, hydrogen may become one of the most environmentally friendly and sustainable sources of energy available.
