Hydrogen is an energy carrier and can be used to store and deliver energy as needed. When used in a fuel cell, the hydrogen atom dissociates into a positively charged hydrogen ion and a negatively charged electron which is diverted to an electric load. A fuel cell can be used to power anything in much the same way that batteries are used.
Natural gas was first used in America for lighting in 1816. [14] Since then, natural gas has grown in importance, especially for electricity generation. US natural gas production peaked in 1973, [15] and the price has risen significantly since then. Coal provided the bulk of US energy needs well into the 20th century. Most urban homes had a ...
A fuel cell vehicle (FCV) or fuel cell electric vehicle (FCEV) is an electric vehicle that uses a fuel cell, sometimes in combination with a small battery or supercapacitor, to power its onboard electric motor. Fuel cells in vehicles generate electricity generally using oxygen from the air and compressed hydrogen.
Ethanol fuel in Brazil is produced from sugarcane, which yields much more fuel per acre than the corn used for ethanol production in the United States. In the United States, oil is primarily consumed as fuel for cars, buses, trucks and airplanes (in the form of gasoline, diesel and jet fuel). Two thirds of US oil consumption is due to the ...

Sketch of Sir William Grove's 1839 fuel cell. The first references to hydrogen fuel cells appeared in 1838. In a letter dated October 1838 but published in the December 1838 edition of The London and Edinburgh Philosophical Magazine and Journal of Science, Welsh physicist and barrister Sir William Grove wrote about the development of his first crude fuel cells.
Fossil fuel regulations are part of the energy policy in the United States and have gained major significance with the nation's strong dependence on fossil fuel-based energy. [1] Regulatory processes are established at the federal and state level due to the immense economic, socio-political and environmental impact of fossil fuel extraction and ...
Hydrogen pipeline transport is a transportation of hydrogen through a pipe as part of the hydrogen infrastructure. Hydrogen pipeline transport is used to connect the point of hydrogen production or delivery of hydrogen with the point of demand, pipeline transport costs are similar to CNG, [9] the technology is proven, [10] however most hydrogen is produced on the place of demand with every 50 ...
