India’s pursuit of cleaner transportation is accelerating with the development of a groundbreaking retrofit system. Researchers have engineered a system capable of converting existing diesel engines to run on 90% hydrogen. This technology promises to dramatically reduce carbon dioxide and nitrous oxide emissions while simultaneously improving efficiency by up to 26%. The system involves replacing the diesel injection system and introducing hydrogen directly into the engine, with independent control over the injection timing for both fuels. This advancement allows businesses to significantly cut emissions without discarding existing machinery, offering a practical solution for a sustainable future. The system’s ability to efficiently utilize low-quality hydrogen is another notable advantage. With the Indian government’s focus on hydrogen infrastructure, such retrofit kits could become widespread. Various companies are also developing similar technologies, including the HYDI, a Direct Injection Device that generates hydrogen on the go, potentially reducing fuel consumption by 5–13%.
