Where will it come from?
Hydrogen production Because pure hydrogen does not occur naturally on Earth in large quantities, it usually requires a primary energy input to produce on an industrial scale.
This method can use wind, solar, geothermal, hydro, fossil fuels, biomass, nuclear, and many other energy sources. Steam-methane reforming, the current leading technology for producing hydrogen in large quantities,  extracts hydrogen from methane.
However, this reaction releases fossil carbon dioxide and carbon monoxide into the atmosphere which are greenhouse gases exogenous to the natural carbon cycle, and thus contribute to global warming which is rapidly heating the Earth's oceans and atmosphere.
One of the challenges of using hydrogen as a fuel comes from being able to efficiently extract hydrogen from these compounds. Currently, steam reforming, which combines high-temperature steam with natural gas, accounts for the majority of the hydrogen produced.
The heat in a hydrogen flame is a radiant emission from the newly formed water molecules. The water molecules are in an excited state on initial formation and then transition to a ground state; the transition releasing thermal radiation.
Historically, carbon has been the most practical carrier of energy, as hydrogen and carbon combined are more volumetrically dense, although hydrogen itself has three times the energy density per weight as methane or gasoline. Although hydrogen is the smallest element and thus has a slightly higher propensity to leak from venerable natural gas pipes such as those made from iron, leakage from plastic polythylene PE pipes is expected to be very low at about 0.
As the cost of producing electricity via wind turbines and solar PV falls below the cost of natural gas, electrolysis becomes cheaper than SMR. Hydrogen economy Hydrogen fuel can provide motive power for liquid-propellant rocketscars, boats and airplanes, portable fuel cell applications or stationary fuel cell applicationswhich can power an electric motor.
This eliminates range anxiety as the vehicles can fill up on diesel. Minor modifications are needed to the engines, as well as the addition of hydrogen tanks at a compression of bars.
A lower price would be needed to compete with gasoline in the US, as gasoline is not exposed to high taxes at the pump. Fuel cell engines are two to three times more efficient than combustion engines, meaning that much greater fuel economy is available using hydrogen in a fuel cell.A hydrogen fuel cell electric vehicle is powered by a group of individual fuel cells, known as a fuel cell leslutinsduphoenix.com stack is designed to contain enough cells to provide .
This New Cheap Method Of Generating Hydrogen Could (Maybe?) it’s possible to make hydrogen from water by splitting water molecules with electrolysis.
it could mean hydrogen fuel that. Hydrogen May Prove Fuel of the Future the most immediate sources of its hydrogen will probably come from natural gas, a fossil fuel.
California law requires that 33 percent of hydrogen. Hydrogen has the highest energy content of any common fuel by weight. On the other hand, hydrogen has the lowest energy content by volume. It is the lightest element, and it is a gas at normal temperature and pressure.
Hydrogen as an Energy Carrier. Hydrogen is considered as a secondary source of energy, commonly referred to as an energy carrier. There are two possible sources for the hydrogen: For example, you could have a box in your garage producing hydrogen from tap water, and you could fuel your car with that hydrogen.
You are using fossil fuel as the source of hydrogen for the hydrogen economy. This approach reduces air pollution, but it doesn't solve either the greenhouse. On December 15, I had talked about hydrogen degassing in Russia and the Ukraine as being a possible fuel source.
The theory is that it is possible to drill for hydrogen streams approximately 1/2 miles under the Earth’s surface to tap into these streams.
