Canadian and Australian mines are big on wanting hydrogen ventilation in underground mining operations, and Canada will likely lead the introduction of hydrogen ventilation and green mobility beyond the openpit environment, says Hydrogen South Africa (HySA) Infrastructure Centre director Professor Dmitri Bessarabov of the North-West University and the Centre for Scientific and Industrial Research. Bessarabov, who addressed the South African Institute of Electrical Engineering at a virtual event on hydrogen, showed a picture of himself 3.5 km down a hard-rock mine in Canada, a mining jurisdiction he believes will be the first to adopt emission-free hydrogen ventilation technology underground.
