Breakthrough Retrofit Technology Allows Diesel Engines to Use 90% Hydrogen

A new retrofit system offers a promising solution for reducing emissions from existing diesel engines. The system, developed by UNSW researchers, enables diesel engines to run on up to 90% hydrogen, resulting in substantial reductions in carbon dioxide and nitrous oxide emissions while boosting efficiency. This retrofit technology is designed to add hydrogen directly to the engine, replacing the existing diesel injection system, and provides independent control over the timing of both hydrogen and diesel injection. The system’s ability to utilize low-quality hydrogen is a key advantage. Moreover, the stratified hydrogen injection technique employed in this technology helps reduce nitrous oxide emissions. The Indian government’s focus on hydrogen processing could facilitate the widespread adoption of such retrofit kits. The commercialization of these kits is being planned by UNSW, targeting fleet operators and others who have access to hydrogen supplies.
