Des scientifiques découvrent une source naturelle d'hydrogène dans des roches canadiennes

Des chercheurs ont découvert que des roches anciennes situées sous l'Ontario produisent naturellement de l'hydrogène gazeux en quantités mesurables. Cette découverte pourrait offrir au Canada une nouvelle source nationale d'énergie propre.

Des scientifiques de l'Université de Toronto et de l'Université d'Ottawa ont mesuré l'hydrogène s'échappant de forages dans une mine en activité près de Timmins. Le gaz s'échappe à un débit moyen de 0,008 tonne par an pour chaque forage et ce phénomène peut perdurer pendant au moins une décennie. Si l'on extrapole ces données aux près de 15 000 forages du site, le total atteint plus de 140 tonnes par an, soit assez pour alimenter plus de 400 foyers chaque année avec 4,7 millions de kilowatts d'énergie.

Scientists develop sunlight method to convert plastic waste into hydrogen

4 mai 2026 Rapporté par l'IA

Researchers at the University of Adelaide have devised a solar-powered process to transform plastic waste into clean hydrogen fuel and other chemicals. The technique, known as solar-driven photoreforming, uses sunlight and photocatalysts to break down plastics at low temperatures. Early experiments show promising hydrogen yields and system stability.
