What is a byproduct of hydrogen as an energy source?
It is a clean-burning fuel, and when combined with oxygen in a fuel cell, hydrogen produces heat and electricity with only water vapor as a by-product.
What is hydrogen alternative energy?
Hydrogen is considered an alternative fuel under the Energy Policy Act of 1992. The interest in hydrogen as an alternative transportation fuel stems from its ability to power fuel cells in zero-emission vehicles, its potential for domestic production, and the fuel cell’s fast filling time and high efficiency.
Is hydrogen an alternative energy source?
Hydrogen, when used in a fuel cell to provide electricity, is a zero tailpipe emissions alternative fuel produced from diverse energy sources.
What does hydrogen get converted into?
In the core of the Sun hydrogen is being converted into helium. This is called nuclear fusion. It takes four hydrogen atoms to fuse into each helium atom.
Why is hydrogen an energy carrier and not an energy source?
Hydrogen, like electricity, is regarded as an energy carrier, not an energy source, because hydrogen as a gas (H2) doesn’t exist naturally on Earth. It requires much energy to produce hydrogen gas, but in this form, it can deliver or store tremendous amounts of energy.
How is hydrogen produced from renewable energy?
Electrolysis: An electric current splits water into hydrogen and oxygen. If the electricity is produced by renewable sources, such as solar or wind, the resulting hydrogen will be considered renewable as well, and has numerous emissions benefits.
What happens when hydrogen burns?
In a flame of pure hydrogen gas, burning in air, the hydrogen (H2) reacts with oxygen (O2) to form water (H2O) and releases energy. If carried out in atmospheric air instead of pure oxygen, as is usually the case, hydrogen combustion may yield small amounts of nitrogen oxides, along with the water vapor.
What are the products of a hydrogen fusion reaction?
Fusion is the process that powers the sun and the stars. It is the reaction in which two atoms of hydrogen combine together, or fuse, to form an atom of helium. In the process some of the mass of the hydrogen is converted into energy.
What is hydrogen element used for?
Hydrogen is a very useful element. It is used to make ammonia for fertilizers, refining metals, and methanol for making artificial material like plastics. Hydrogen is also used as a rocket fuel where liquid hydrogen is combined with liquid oxygen to produce a powerful explosion.
What is hydrogen and uses of hydrogen?
Following are some important uses of hydrogen: Hydrogen is used in the synthesis of ammonia and the manufacture of nitrogenous fertilizers. Hydrogenation of unsaturated vegetable oils for manufacturing vanaspati fat. It is used in the manufacture of many organic compounds, for example, methanol.
What is the main source of energy for making hydrogen?
Sources of Energy. Hydrogen can be produced from diverse, domestic resources. Currently, most hydrogen is produced from fossil fuels, specifically natural gas. Electricity—from the grid or from renewable sources such as biomass, geothermal, solar, or wind—is also currently used to produce hydrogen.
What is hydrogen as an alternative fuel?
Hydrogen as an Alternative Fuel. The energy in 2.2 pounds (1 kilogram) of hydrogen gas is about the same as the energy in 1 gallon (6.2 pounds, 2.8 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.
What is hydrogen and how does it work?
Hydrogen is an energy carrier, not an energy source and can deliver or store a tremendous amount of energy. Hydrogen can be used in fuel cells to generate electricity, or power and heat. Today, hydrogen is most commonly used in petroleum refining and fertilizer production, while transportation and utilities are emerging markets.
How do you make hydrogen from water?
Hydrogen Basics. Hydrogen can also be produced from water through electrolysis. This is more energy intensive but can take advantage of inexpensive excess renewable energy, such as wind or solar, while avoiding the harmful emissions associated with other kinds of energy production.
