The Use of Hydrogen Injection for Particulate Emission Reduction in Heavy-Duty Diesel Engines

One of the most critical operations for underground mining companies is air quality control. Companies spend nearly 20% of their operating budget ensuring fresh air is supplied to underground workers. The ability to reduce the cost of ventilation by reducing underground emissions is therefore a valuable pursuit. The goal of this applied research project is to determine to what degree injecting small amounts of hydrogen gas into the air intake of heavy duty diesel engines reduces particulate emissions. The industry partner for this project, Ontario Hydrogen Energy Corporation, anticipates a significant reduction in harmful particulate emissions if their technology is adapted for and used by underground machinery. This project is also timely from a health and safety perspective. Within the last two months, the World Health Organization has reclassified diesel particulate emissions as carcinogenic. Substantially reducing these harmful emissions using this hydrogen delivery unit will work to ensure safe working conditions both above, and below ground.
