Researchers from the University of Toronto and University of Ottawa have discovered that billion-year-old rocks in the Canadian Shield are naturally releasing large amounts of clean hydrogen gas from mine boreholes near Timmins, Ontario. A single mine site produces more than 140 metric tons of hydrogen annually and the flow could continue for a decade or more. The discovery, published May 2026, points to a potential new domestic clean-energy source that requires no electricity or fossil fuels to produce.
