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
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
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.
