Scientists in Canada are investigating the potential of naturally occurring hydrogen in the Canadian Shield, aiming to transform the energy landscape by providing a low-cost, scalable source of clean fuel amidst ongoing technological and geological challenges.
Hydrogen is often described as a fuel of promise and frustration: when used it can produce only water vapour, yet making it can be energy-intensive and costly. That tension has long limited its role in industrial decarbonisation, especially where investors and operators need low-carbon options that are both scalable and commercially credible.
A potentially important shift is now being explored in Canada. Scientists believe the Canadian Shield, the vast ancient rock formation stretching across much of the country, could contain naturally occurring hydrogen deposits large enough to support global energy demand for an extraordinary period. Scientific American reported that researchers see reservoirs of the gas in many regions, and that the main challenge is locating where hydrogen has been released, accumulated and preserved.
The appeal is obvious. If naturally generated hydrogen can be extracted at scale, it could avoid some of the cost and emissions associated with producing green hydrogen through electrolysis. The Cooldown noted that the U.S. Department of Energy has suggested such hydrogen might eventually be produced for less than $1 per kilogram, though that figure remains aspirational rather than proven at commercial scale. Startup Vema Hydrogen has already begun test drilling in Quebec, but the key questions remain geological, technical and economic: where the richest deposits sit, and how to recover them efficiently.
For industrial users, the broader significance is that clean hydrogen is increasingly being evaluated not as a universal solution, but as a targeted one. Airbus has said hydrogen remains one of the most promising zero-emission technologies for future aircraft, while also acknowledging major barriers around storage, infrastructure, cost and safety. In June 2025, Airbus and MTU Aero Engines deepened work on hydrogen fuel-cell propulsion, signalling continued momentum in aviation. In Germany, researchers are also testing hydrogen applications in shipping and propulsion systems at new facilities designed to assess performance in real conditions.
Storage remains another critical bottleneck. Chinese researchers have recently developed a prototype gas-solid hydride ion battery that can hold hydrogen and energy at room temperature and normal pressure, which could ease one of the sector’s most stubborn logistical problems. Together, these developments suggest the hydrogen economy is moving away from abstract ambition and towards a more segmented reality, in which natural hydrogen finds, fuel cells, and better storage technologies each play a distinct industrial role.

Finding such reservoirs could help accelerate a global energy transition, but until now, geologists only had a piecemeal understanding of how large hydrogen accumulations form — and where to find them. “The game of the moment is to find where it has been released, accumulated and preserved,” Chris Ballentine, a professor and chair of geochemistry at the University of Oxford and lead author of a new review article on hydrogen production in Earth’s crust, told Live Science in an email.

But the road to hydrogen-powered aircraft requires significant effort inside the aviation industry and beyond. From hydrogen storage, cost and infrastructure to public perceptions about safety, the aviation sector is working to mature the technology while tackling some major challenges. Hydrogen is increasingly considered as one of the most promising zero-emission technologies for future aircraft. However, despite the fact that hydrogen has an energy-density-per-unit mass that is three times higher than traditional jet fuel, a variety of challenges must be addressed before widespread adoption can happen.
- https://www.airbus.com/en/newsroom/press-releases/2025-06-airbus-and-mtu-aero-engines-advance-on-hydrogen-fuel-cell – Paris, France, 18 June 2025 – Airbus and MTU Aero Engines have signed a Memorandum of Understanding (MoU) to progress together on hydrogen fuel cell propulsion, a promising and critical technology to decarbonise aviation. This MoU was signed today during the 55th Paris Airshow by Bruno Fichefeux, Airbus’ Head of Future Programmes and Dr. Stefan Weber, MTU’s SVP Engineering and Technology. The partnership draws on the combined expertise of Airbus, a leading aircraft manufacturer and pioneer in hydrogen-powered aviation through its ZEROe project, and MTU Aero Engines, a globally recognised engine expert for commercial and military aircraft. It follows Airbus’ decision to focus its research effort on a fully electric, hydrogen-powered aircraft with a fuel cell engine, a field in which MTU has developed recognised expertise through its Flying Fuel Cell concept. The agreement sets out a three-step roadmap for the development of a hydrogen-powered fuel cell engine suitable for the commercial aviation market.

Despite the progress already made, there are still a number of physical hurdles to overcome and new technologies to develop before reduced-emission medium-haul flights can be powered by hydrogen. Researchers at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) are tackling this challenge at the newly built Future Propulsion Test Facility (FPT).
- https://www.airbus.com/en/innovation/energy-transition/hydrogen – After almost five years of research into hydrogen propulsion, Airbus has determined that the most promising technology will be hydrogen fuel cells. This means the future ZEROe aircraft will be fully electric. It will feature four electric propellers, each powered by hydrogen fuel cells, which transform the hydrogen into electricity through a chemical reaction.
- https://www.thecooldown.com/green-tech/hydrogen-power-future-canadian-shield/ – Hydrogen power has limitations since it requires energy to produce in the first place, but with the right applications, it can make a big difference toward lowering pollution. Hydrogen is a complicated clean energy source. On the one hand, when burned, it only releases water vapor. On the other hand, it’s energy-intensive to produce, kind of defeating the point. And green hydrogen — producing it using only clean energy sources — can be very expensive upfront. But there’s hope for hydrogen to become a viable clean and affordable energy option in the future. According to scientists, there may be enough naturally occurring hydrogen in the Canadian Shield — a massive rock formation spanning roughly half the country — to cover the world’s energy needs for around 170,000 years. On top of that, according to the U.S. Department of Energy, that hydrogen could potentially be produced for less than $1 per kilogram. Startup Vema Hydrogen has begun test drilling in Quebec, but it remains to be seen where the strongest deposits are and how to efficiently recover the hydrogen.
