No, diesel may not be dead!

In Australia, a team of engineers from the University of Sydney have developed an engine that runs on both hydrogen and diesel! Diesel may not be living its last days…

Hydrogen is developing very slowly in the automotive industry. At Motor Show which is currently taking place in Paris, several vehicles using this energy have however been presented, such as the NamX HUV or theHopium Machina for example, as well as recharging solutions for models currently running on hydrogen.

Some even see a very sensible alternative to electric powerthanks to a superior autonomy and one very short recharge time.

And while these vehicles are developing, other energies are in great difficulty, such as diesel for example. But thanks to a team of Australian researchers, this fuel may not live its last days!

A miracle engine?

It seems very strange, but it is nevertheless true. Scientists from the University of New South Wales (UNSW) in Sydney, Australia have managed to operate a diesel motor transformed with a hydrogen mixture and of conventional diesel.

And their system even made it possible to reduce CO2 emissions by more than 85% ! But how does the miracle engine work?

Professor Shawn Kook, Director of the Engine Research Laboratory, explains: “ We have shown that we can take diesel engines and convert them to cleaner engines running on hydrogen« .

To do this, the initial diesel injection was kept and a hydrogen injection was added. Thanks to independently controlled supply of the two fuels and stratification in the cylinder, harmful exhaust gases can be avoided during combustion.

Is this the salvation for all diesel engines?

If this is good news on paper, the transformation seems for the moment rather planned for the big engines. According to the researchers, ” any diesel engine used in trucks and motorized machinery in the transport, agriculture and mining sectors could eventually be converted to the new hybrid system in just a few months« .

Hydrogen is interesting because it is a fuel that does not directly emit CO2. Indeed, the gas is produced by the decomposition of water into hydrogen and oxygen using electricity (electrolysis). If the necessary energy is produced by solar or wind energy, the production does not harm the environment either. This is referred to as “green hydrogen”.

Normally, hydrogen is transformed into electric energy in vehicles equipped with a Fuel cell. Traditional hydrogen cars are therefore in fact electric vehicles with an integrated mini power plant. Instead of smelly exhaust fumes, the use of H2 in fuel cells produces only harmless water vapor.

Currently, the researchers are looking for investors to commercialize the results of their laboratory. If they find it, maybe trucks, cargo ships and transport buses will soon be running with this type of engine!
