Engineers from UNSW Sydney have successfully converted a diesel engine to run as a hydrogen-diesel hybrid engine, reducing the CO2 emissions by more than 85 per cent in the process.
The team, led by Professor Shawn Kook from the School of Mechanical and Manufacturing Engineering, spent around 18 months developing its 'Hydrogen-Diesel Direct Injection Dual-Fuel System' that means existing diesel engines could run using 90 per cent hydrogen as fuel.
The researchers said that any diesel engine used in trucks and power equipment in the transport, agriculture and mining industries could ultimately be retrofitted to use the new hybrid system in just a couple of months.
Green hydrogen, which is produced using clean renewable energy sources such as wind and solar, is much more environmentally friendly than diesel.
In a paper published in the International Journal of Hydrogen Energy, Professor Kook’s team showed that using their patented hydrogen injection...
