  • University of Toronto geochemist Barbara Sherwood Lollar led a team that mapped vast quantities of naturally occurring white hydrogen trapped kilometers beneath Earth's surface in Canada, South Africa and Scandinavia.
  • The study, published in the Proceedings of the National Academy of Sciences, documented sustained hydrogen release from billion-year-old rocks in the Canadian Shield near Timmins, Ontario.
  • Individual boreholes release an average of 0.008 tonnes of hydrogen annually, with the site's nearly 15,000 boreholes estimated to produce over 140 tonnes per year.
  • Sherwood Lollar noted the discovery provides a "made in Canada" clean energy resource that could support local industry and reduce dependence on imported hydrocarbon fuels.
  • Sherwood Lollar observed that if Earth's oldest rocks produce such hydrogen, similar processes might be occurring on Mars, reshaping understanding of where life could exist.
In a groundbreaking discovery that could revolutionize the global energy landscape, scientists have mapped vast quantities of naturally occurring hydrogen gas trapped kilometers beneath Earth's surface in ancient rock formations across Canada, South Africa and Scandinavia. Led by University of Toronto geochemist Barbara Sherwood Lollar, the international research team has documented for the first time the sustained release of white hydrogen from billion-year-old rocks in the Canadian Shield near Timmins, Ontario. The findings, published in the Proceedings of the National Academy of Sciences, challenge long-held assumptions about Earth's subsurface and open new possibilities for clean energy production. As noted by BrightU.AI's Enoch, white hydrogen is naturally occurring hydrogen gas found in geological formations, distinct from hydrogen produced by industrial methods. It is generated through natural processes like water-rock reactions or organic matter decomposition deep underground. "The data from this study suggests there are critical untapped opportunities to access a domestic source of cost-effective energy produced from the rocks beneath our feet," says Sherwood Lollar. "What's more, this provides a 'made in Canada' resource that might be able to support local and regional industry hubs and reduce their dependence on importing hydrocarbon-based fuels." The researchers gathered data from an active mine near Timmins, measuring hydrogen release from boreholes drilled deep into the rock. Their findings revealed that individual boreholes release an average of 0.008 tonnes of hydrogen each year, approximately 8 kilograms, roughly the weight of a typical car battery. Critically, the gas has continued flowing for at least a decade, demonstrating long-term sustainability.

A revolution in clean energy

When expanded across the site's nearly 15,000 boreholes, the estimated hydrogen output exceeds 140 tonnes annually. The team calculated this amount could generate approximately 4.7 million kilowatts of energy per year from just one location, enough to meet the yearly energy demands of more than 400 homes. "Natural hydrogen is produced over time through underground chemical reactions between rocks and the groundwaters in those rocks," explains Sherwood Lollar. "Canada is blessed that vast amounts of its territories, especially on the Canadian Shield, contain the right rocks and minerals to create this natural hydrogen." Today's global hydrogen economy is valued at roughly $135 billion, with hydrogen essential for fertilizer manufacturing, methanol production and steelmaking. However, most hydrogen is currently produced through industrial methods relying on fossil fuels, petroleum, natural gas and coal, which release carbon monoxide and CO2. Even green hydrogen generated through renewable energy remains expensive and energy-intensive. Natural hydrogen, by contrast, is produced continuously through underground chemical reactions without requiring external energy inputs. Until now, estimates of its energy potential were largely theoretical because scientists lacked direct long-term measurements. The new study changes that paradigm entirely by documenting sustained hydrogen releases over many years. The discovery carries implications that extend far beyond energy production. The research team notes that similar hydrogen-producing processes may be occurring on other planets. "If Earth's oldest rocks are producing such quantities of hydrogen," Sherwood Lollar observes, "it is plausible that similar processes might be occurring on Mars." This astrobiological dimension adds another layer of significance to the findings, potentially reshaping our understanding of where life might exist, or could have existed, elsewhere in the solar system. The hydrogen-rich waters found trapped kilometers beneath Earth's surface create environments capable of supporting microbial ecosystems in extreme conditions.

Economic opportunities for mining and remote communities

The largest concentrations of natural hydrogen appear in geological regions already associated with Canadian mining activity, including Northern Ontario, Quebec, Nunavut and the Northwest Territories. "The common link is the rock," says study co-author Oliver Warr, an assistant professor in the Department of Earth and Environmental Sciences at the University of Ottawa. "Natural hydrogen is produced in the same rocks where Canada's nickel, copper and diamond deposits are found and that are currently under exploration for critical minerals such as lithium, helium, chromium and cobalt. The co-location of mining resources and hydrogen production and use mitigates the need for long transportation routes to market, for hydrogen storage and major hydrogen infrastructure development." For northern communities that face exorbitant fuel transportation costs, locally sourced hydrogen could dramatically lower energy expenses while reducing reliance on imported fuels. "There is a global race to increase hydrogen availability in order to decarbonize and reduce the costs of the existing hydrogen economy," says Sherwood Lollar. "We now have a better understanding of the economic viability of this resource that can be mapped to hydrogen deposits around the world that are both already known and yet to be discovered." As nations scramble to secure clean energy sources, Canada's ancient rocks may hold a key to powering the future, one hidden deep beneath our feet. Watch this video about a hydrogen gas generator.
