New Retrofit System Converts Diesel Engines to Run on 90% Hydrogen

Researchers have developed a retrofit system capable of converting existing diesel engines to run on 90% hydrogen, a significant step toward reducing emissions and improving efficiency. This technology, developed by UNSW researchers, aims to help businesses lower their environmental impact without replacing existing assets. The system replaces the diesel injection system, introducing hydrogen directly into the engine and allowing independent control of hydrogen and diesel injection timing. This method efficiently utilizes low-quality hydrogen and employs a stratified hydrogen injection technique to minimize nitrous oxide emissions, potentially below those of conventional diesel engines. The Indian government’s plans for eco-friendly mobility include developing hydrogen processing, which could pave the way for widespread adoption of such retrofit kits. UNSW intends to commercialize the kits, targeting fleet and generator operators like mining operations with existing hydrogen supplies.
