How do the HYDI units work?

The HYDI hydrogen on demand system supplies hydrogen gas to a diesel engine’s intake. On a mass-to-mass basis, hydrogen has three times the energy content of diesel and delivers a higher flame speed to improve combustion efficiency.  This powerful combination reduces fuel consumption, carbon and greenhouse gas exhaust emissions and increases performance.


Sophisticated safety features ensure the HYDI Unit
does not store hydrogen and only produces it
while the engine is running.


Durable welded 316 stainless-steel construction
ensures the HYDI Unit performs optimally in harsh


A HYDI Unit offers rapid return on investment
based on fuel cost savings.


Cutting-edge electronics allow HYDI Units to
minimise the electrical input required for
maximum output of hydrogen.


HYDI Units use the latest technology. Electronics
monitor and optimise hydrogen production while
Bluetooth enables the operation status to be
displayed in real time.


The effectiveness of our units has been proven
over years of field trials. Independent testing at
the University of South Australia is validating
our results.


HYDI Units do not contain or require any base
chemicals, just demineralised water.
