How to make hydrogen


How to make hydrogen


The basis as to how to make hydrogen is nothing that has not been heard before.  This is the most abundant element.  The basic operation of electrolysis is combining water with an electrolyte like salt.  Run a current through the solution making the molecules split into hydrogen, and oxygen gases.  There is some controversy about the price of metals and the costs of them that should be used to make this process work.

There are different ways to get hydrogen from water also fossil fuels.  Steam reforming is one way it is about 80% efficient and uses high temperatures around (700-1100 degrees C) to get the hydrogen from natural gas.  Hydrogen can also be generated through a much lower temperature at about 130 degrees C.  The oxygen atom is taken out of the water (steam), to oxidize, this provided power to keep the reaction going.  When additional heat is required it is usually supplied by burning a portion of the methane gas.

There is approximately 5% of the hydrogen being produced is done with electrolysis.  There are two types that are used the most, solid oxide cells and alkaline cells.  These cells operate at unusually high concentrations and high temperatures of around 200 degrees C.   Hydrogen by itself is not an energy source as it is not a naturally occurring fuel.  There  are extremely high possibilities for future hydrogen use in the coming economy.

Splitting from water is one technology that has been explored and being used in various forms of how to make hydrogen from water.  The most common technique is also electrolysis for this also.  Photocatalytic is the conversion of solar to hydrogen by the process of water splitting.  This is a cleaner and more renewable form of seperation around to date.  When this method is used if the photocatalysts are suspended in the water instead of photovoltaic with an electrolytic process the reaction is done in one step, and far more efficiently produced.

Fermentative production of hydrogen is a conversion of the natural substrate to a biohydrogen.  This uses a diverse group of bacteria and multi enzymes in three steps that are similar to anaerobic conversion. This process does not require light energy and can be constantly producing hydrogen from the organic’s day and night.  Fermentative hydrogen can be produced using green algae as direct biophotolysis.  Biohydrogen production can also be done in bioreactors that make uses of feedstocks.  The most common being the waste and the process involves the bacteria that feeds on the hydrocarbons and exhaling the hydrogen.

Currently hydrogen production is limited to agricultural and industrial areas, where the gas is produced on site with methane.  They believe that one day in the future drivers should be able to fill their cars using a hydrogen fuel cell from the pumps with a built in electolyzer.  The energy needed when producing the hydrogen is solar or wind powered making the overall process emissions free and totally green.

Renewable hydrogen is currently being used in ways such as landfill gas, to help produce hydrogen in a steam reformer, and hydrogen produced by electrolysis.  These types of hydrogen fuel when produced with a renewable source of energy like solar or wind, makes it a renewable fuel.  Hydrogen is the chemical element with the atomic number 1.  The elemental symbol is H and is the most abundant chemical and the lightest in the universe.

Most starts are made up of Hydrogen in the plasma state.  This is remarkably rare on the Earth itself.  How to make hydrogen ; t was first made artificially in the early 16th century.   This was done by mixing metals with strong acids and was found that it produced water when it was burned.  Hydrogen at a regular temperature and pressure is an unscented, tasteless, colorless nontoxic, yet immensely combustible gas.  Hydrogen was industrially produced and used near the production site.

One main concern is that it can embrittle several types of metals causing metallurgy.  This complicates the design of storage tanks and pipelines. There are many security issues that need to be followed to reduce potential fires, and even detonations when being mixed with air it can be an asphyxiate in its pure form.  Liquid hydrogen is a cryogen and can cause frostbite as it is frightfully cold.  It can dissolve many kinds of metal, and if it is being stored in some metal storage container cold leak out, and spontaneously ignite when it hits the outside air.  A hydrogen fire is almost invisible and extremely hot.  Making it an extremely dangerous element to deal with, and should be controlled with the utmost attention and care.
