Newly developed hydrogen-powered diesel engine concept decreases pollution

A novel idea created by academics at the University of New South Wales can reduce the environmental impact of diesel engines.

They have modified a unit such that it uses 10% less diesel fuel than it did previously. Hydrogen is the source of the remaining energy. Emissions of CO2 and other pollutants can be cut by 85% in this approach.

The team is preserving direct injection for diesel but adding another system of this kind to force more hydrogen into the cylinder. Shawn Kook is the project leader and is from the School of Mechanical and Manufacturing Engineering. The new hybrid system can be modified to work with any diesel engine that is now utilized in trucks and other machinery in the transportation, agricultural, and mining sectors.

Green hydrogen produced by electrolysis with wind and/or solar electricity yields the best results. The best prerequisites for this are in Australia. Huge wind and solar parks are being constructed or planned by a number of consortiums; the electricity they generate will be utilized to produce hydrogen. Large portions of it are to be exported, including to Europe, in accordance with prior plans. However, Australia has such a sizable landmass that is suited for the generation of green electricity that colossal quantities might also be used for domestic use.

To lower CO2 emissions, diesel and hydrogen might have been combined. However, a lot of nitrogen oxides would be released as a result of the high combustion temperature, which is bad for your health and also kills plants. The temperatures can be managed more precisely with separate infusion. The team is seeking investors and interested businesses in order to commercialize the novel system within the next 12 to 24 months.
