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. Hydrogen is considered as a secondary source of energy, commonly referred to as an energy carrier energy carriers are used to move, store and deliver energy in a form that can be easily used electricity is the most well-known example of an energy carrier.
Hydrogen is usually considered an energy carrier, like electricity, as it must be produced from a primary energy source such as solar energy, biomass, electricity (eg in the form of solar pv or via wind turbines), or hydrocarbons such as natural gas or coal.
Hydrogen is the simplest element on earth—it consists of only one proton and one electron—and it is an energy carrier, not an energy source hydrogen can store and deliver usable energy, but it doesn't typically exist by itself in nature and must be produced from compounds that contain it. In a future full hydrogen economy, primary energy sources and feedstock would be used to produce hydrogen gas as stored energy for use in various sectors of the economy producing hydrogen from primary energy sources other than coal, oil, and natural gas, would result in lower production of the greenhouse gases characteristic of the combustion of these fossil energy resources.
Hydrogen fuel hydrogen is one of two natural elements that combine to make water hydrogen is not an energy source, but an energy carrier because it takes a great deal of energy to extract it from water. Use of hydrogen nearly all of the hydrogen consumed in the united states is used by industry for refining petroleum, treating metals, producing fertilizer, and processing foods rocket fuel is the main use of hydrogen for energy the national aeronautics and space administration (nasa) is the largest user of hydrogen as a fuel.
The energy in 22 pounds (1 kilogram) of hydrogen gas is about the same as the energy in 1 gallon (62 pounds, 28 kilograms) of gasoline because hydrogen has a low volumetric energy density, it is stored onboard a vehicle as a compressed gas to achieve the driving range of conventional vehicles.
Hydrogen, when used in a fuel cell to provide electricity, is an emissions-free alternative fuel produced from diverse energy sources currently, drivers of fuel cell electric vehicles (fcevs) can fuel up at retail stations in less than 5 minutes and obtain a driving range of more than 300 miles. Hydrogen basics hydrogen is a clean-burning fuel, and when combined with oxygen in a fuel cell, it produces heat and electricity with only water vapor as a by-product but hydrogen does not exist freely in nature: it is only produced from other sources of energy , so it is often.
