Hydrogen-Powered Future: Retrofit System Transforms Diesel Engines

A new retrofit system offers a significant leap toward eco-friendly mobility. This technology enables the conversion of existing diesel engines to operate on a 90% hydrogen blend. The system, developed by UNSW researchers, aims to drastically reduce emissions and boost efficiency. The innovative design replaces the diesel injection system with a direct hydrogen injection mechanism, offering independent timing control for both fuels. A key benefit is the system’s ability to process low-grade hydrogen, making it versatile. By using stratified hydrogen injection, the technology minimizes nitrous oxide emissions below levels seen in conventional diesel engines. The project aligns with the Indian government’s broader initiatives to promote hydrogen as a viable energy source. The retrofit kits are being planned for commercialization, with fleet and generator operators as initial targets. Other companies are also working on similar solutions, like the HYDI, which generates hydrogen as needed, reducing the need for external infrastructure and potentially cutting fuel use.
