A new retrofit system offers a promising solution for converting existing diesel engines to utilize hydrogen fuel, as a part of a larger initiative. The technology, developed by UNSW researchers, allows diesel engines to run on up to 90% hydrogen, significantly lowering carbon dioxide and nitrous oxide emissions while increasing efficiency. The system replaces the diesel injection system, introducing hydrogen directly into the engine and allowing independent control of hydrogen and diesel injection timing. This retrofit solution efficiently processes low-quality hydrogen. The stratified hydrogen injection method creates varying hydrogen concentrations within the cylinder, lowering nitrous oxide emissions. This offers businesses a method to reduce emissions without replacing fully functional machinery. Commercialization plans are underway, focusing on fleet operators and those with existing hydrogen infrastructure.
