According to the release, that could provide about 4.7 million kilowatt-hours of energy annually, enough to support the yearly energy needs of more than 400 households.<\/p>\n\n\n\n
Barbara Sherwood Lollar, lead author and professor at the University of Toronto, said the data point to \u201ccritical untapped opportunities\u201d beneath our feet. In practical terms, Canada may have a local clean-energy resource hiding in the same kind of rocks that mining companies already know well.<\/p>\n\n\n\n
Why this fuel matters<\/h2>\n\n\n\n
Hydrogen is already a huge business, worth about $135 billion globally. It is used in fertilizer production, methanol, and steel, which means it is tied not only to clean-energy plans<\/a> but also to food systems and heavy industry.<\/p>\n\n\n\nThe trouble is how most hydrogen is made today. Current industrial processes usually rely on hydrocarbons from fossil fuels<\/a> such as natural gas, oil, or coal, releasing carbon monoxide and CO2 along the way.<\/p>\n\n\n\nGreen hydrogen<\/a>, made with renewable electricity, avoids much of that fossil-fuel problem, but it is still energy-intensive and costly to produce. It also needs transport and storage, which can become a headache for remote regions where every fuel delivery already shows up in the price of power, and eventually, the electric bill.<\/p>\n\n\n\nHow rocks make hydrogen<\/h2>\n\n\n\n
White hydrogen is not manufactured in a factory. It forms underground through chemical reactions between rocks and groundwater, slowly generating hydrogen inside the Earth\u2019s crust.<\/p>\n\n\n\n
That is what makes the Canadian Shield so interesting. The researchers say vast parts of Canada contain rocks and minerals suitable for this process, especially across regions such as northern Ontario, Quebec, Nunavut, and the Northwest Territories.<\/p>\n\n\n\n

Mines could use it first<\/h2>\n\n\n\n
The most realistic near-term use may not be powering big cities. Instead, white hydrogen could first help mines and northern communities cut fuel costs and emissions right where the gas is found.<\/p>\n\n\n\n
That local angle is important. Mines often need steady energy, while remote communities<\/a> can face high costs when diesel or other fuels must be transported over long distances, sometimes through difficult weather and rough terrain.
