Engineers from UNSW Sydney (Australia) have successfully converted a diesel engine to run as a dual-fuel hydrogen-diesel engine, reducing CO2 emissions by more than 85% compared to conventional diesel. The team, led by Professor Shawn Kook from the School of Mechanical and Manufacturing Engineering, spent around 18 months developing the Hydrogen-Diesel Direct Injection Dual-Fuel System that allows existing diesel engines to run using 90% hydrogen as fuel.
The researchers say that any diesel engine used in trucks and power equipment in the transportation, agriculture and mining industries could ultimately be retrofitted to the new hybrid system in just a couple of months.
In a paper published in the International Journal of Hydrogen Energy, Prof. Kook’s team shows that using their patented hydrogen injection system reduces CO2 emissions to just 90 g/kWh—85.9% below…
