Hydrogen can be used as fuel (the same way as natural gas) for vehicles (cars, buses, ...etc) either in gaseous, liquid, or solid form (as metalhydride).
Hydrogen can be used for electricity generation using hydrogen fuel cells.
Hydrogen can be used (as natural gas) as heat source for kocking or heating purposes or industrial applications.
A type of cell where chemical energy is converted into electrical energy is a fuel cell. Fuel cells generate electricity through an electrochemical reaction between a fuel (such as hydrogen or natural gas) and an oxidizing agent (typically oxygen).
When a car is driven, the chemical energy in gasoline is converted into mechanical energy by the engine. The combustion of gasoline in the engine produces heat, which is then converted into kinetic energy that propels the vehicle forward.
Various kinds of energy may be converted into thermal energy.In a fire it is chemical energy that is converted to thermal energy.However:In a nuclear reactor, nuclear energy is first converted to thermal energy, and eventually to electrical energy.In a fire chemical energy is also converted to light energy.In a battery chemical energy is converted to electrical energy.In braking systems kinetic energy is converted to thermal energy.
Hydrogen can be burnt with oxygen and the formation of the chemical bonds between the atoms releases energy as heat. Free hydrogen is normally manufactured by electrolysis from water, and this requires energy to separate the hydrogen-oxygen bonds, and it is this energy that is released when the chemical bonds are re-formed by combustion.
The waste byproducts of hydrogen fuel cells are typically heat and water vapor. As the hydrogen gas is converted into electricity, the only emission produced is water, making fuel cells a clean energy source.
The sun's energy is released when nuclear fusion converts hydrogen atoms into energy. This process involves the fusion of hydrogen nuclei to form helium nuclei, releasing large amounts of energy in the form of light and heat.
In a hydrogen bomb, the process of nuclear fusion converts hydrogen atoms into energy. This occurs when the nuclei of hydrogen isotopes, such as deuterium and tritium, combine to form helium, releasing a large amount of energy in the process.
In the Sun, energy is converted through nuclear fusion. Specifically, hydrogen-1 is converted into helium-4. This releases a huge amount of energy. Of course, the energy was there from the moment the Sun formed - in the form of the fuel, hydrogen-1. The energy is simply converted to another form.
ATP (converted to ADP). Aerobically it is converted back by mitrochondria by oxidizing hydrogen.
The hydrogen in the Sun has nuclear energy (a type of potential energy). When this is fused, it is converted to heat energy. This eventually gets radiated out as light energy.
When hydrogen atoms fuse into helium atoms, a small amount of mass from the hydrogen is converted into a large amount of energy in accordance with Einstein's equation E=mc^2. This energy release results from the difference in mass between the initial hydrogen atoms and the resulting helium atoms.
The hydrogen in the Sun has nuclear energy (a type of potential energy). When this is fused, it is converted to heat energy. This eventually gets radiated out as light energy.
Nuclear fusion. Mainly, hydrogen-1 is converted to helium-4.
Hydrogen-1, which is converted, through nuclear fusion, to helium-4.
The thing the "main sequence" stars have in common is that they get their energy from the fusion of hydrogen (hydrogen-1 is converted into helium-4).
When a rocket is launched, chemical energy from the fuel is converted into thermal energy through combustion, which then creates pressure that propels the rocket upwards through thrust. As the rocket ascends, this kinetic energy is converted into potential energy as it gains altitude.
Hydrogen gas itself is not being destroyed when it is converted to energy. Renewable sources of hydrogen include water electrolysis powered by renewable energy sources like solar or wind power, and biomass gasification. These processes produce hydrogen without depleting finite resources.
