The necessity of hydrogen production from electrolytic water

The necessity of hydrogen production from electrolytic water
 
The progress of human beings is inseparable from the development of science and technology.The development of science and technology is inseparable from the consumption of energy.
 
With the exploitation and utilization of fossil resources, human civilization has achieved a broader development,but the corresponding fossil resources are also less and less. In this way, we have to find more sustainable energy, hydrogen.
 
At present, the vast majority of hydrogen production relies on coal to produce hydrogen and natural gas to produce hydrogen. With the reduction of global fossil resources, we should focus on the most extensive energy on earth, water.Hydrogen production by water electrolysis is no longer a very complex or high-tech product, which has not been vigorously promoted.
 
It is a secondary energy that can only be produced after a large number of fossil resources are needed to generate electricity.Hydrogen production from electrolytic water and the application of hydrogen energy can create a more environmentally friendly home for us and greatly alleviate the earth's air pollution.
 
Electrolysis and the Hydrogen Economy
The worldwide demand for energy puts increasing pressure on the available carbon sources. The combustion of carbon-based fuels, e.g. natural gas and coal, cannot be sustained indefinitely, as carbon resources become depleted, unless effective technology is developed to recover and re-use the carbon dioxide combustion product.
 
Solutions proposed for this re-use include electrolysis or photo-electrolysis of carbon dioxide with water to species such as carbon monoxide and hydrogen, known as “synthesis gas” (syngas), formic acid or methanol, and the production of methanol, catalytically from carbon dioxide and hydrogen. Such approaches require the use of electricity, either directly or indirectly (hydrogen formed from water electrolysis) in electrolysers, for which currently production is dominated by fossil fuel combustion.
 
Hence for sustainable electrolysis, its future use would need to be based on “renewable” sources (hydro, solar, wind and wave) or on photochemical or photo-biological methods using solar energy sources. Notably such energy sources can be used to generate hydrogen via electrolysis or by use of other technologies.
