Hydrogen on Demand

Hydrogen on demand or HOD technology has broad range applications in the automotive, medical and welding industries. In the automotive industry there are two types of hydrogen on demand technologies commonly referred to including systems that will power 100-percent of the car to those that partially power the vehicle.

Hydrogen on demand technology is also used in fueling stations for fuel cell vehicles. Hydrogen can be created on demand by electrolysis of water or by steam reforming natural gas as needed in order to provide fuel for the vehicles.

One exciting field for hydrogen on demand technology is to power small electronic devices and compete with lithium ion batteries. A number of manufacturers including Canon have come out with hydrogen on demand batteries that combine a small fuel cell with a delivery system to provide hours of power to electronics. Small emergency generators can also use hydrogen on demand power.

HOD technology is also useful in the medical field. Deionized or distilled water is used to create hydrogen for gas chromatography, flame ionization detectors, trace hydrocarbon analyzers, HWD detectors or other research applications.

Hydrogen on demand technology is not usually used in atomic hydrogen welding, but is most often used in oxy-hydrogen (HHO gas) welding applications. In this case, water is electrolyzed and the resulting hydroxy gas (hydrogen and oxygen) is burned by the welding torch, often called a water torch since the only emissions are steam and H2O.

The type of hydrogen on demand that I focus upon on this website is HOD for the automotive industry. Hydrogen on demand may be used to power 100-percent of boats, trucks, small unmanned planes and other vehicles such as those created by Millennium Cell.

Using sodium borohydride (NaBH4), a hydrogen-rich chemical compound in combination with water (another hydrogen-rich compound) the H2 can be released and then run through a fuel cell to create electricity or run through an internal combustion engine to generate torque.

But, perhaps the most engaging hydrogen on demand field is the emerging technology of partially running a car on water. Notice, I did not say totally. Water is electrolyzed and a small amount of either hydrogen or oxyhydrogen (via HHO gas generators) is injected into a car's intake system.

This helps the gasoline or diesel to burn more cleanly and completely. In turn the vehicle will use less fuel and the vehicle's emissions will be lowered as well. Hydrogen on demand is here to stay, simply because consumers are demanding it and many inventors are building models and cashing in.
