Amid the slow progress of green hydrogen projects, geologic hydrogen offers a promising, low-cost frontier that could revolutionise industrial decarbonisation if proven viable at scale.
For years, green hydrogen has been promoted as a way to cut emissions in sectors that are difficult to electrify, from steelmaking to industrial shipping. Yet the economics have remained stubbornly weak, and a 2025 study in Nature Energy tracking 190 projects found that only 7% of announced capacity was completed on schedule, underlining how far deployment has lagged behind ambition.
That gap has renewed interest in a less familiar alternative: geologic hydrogen. Rather than producing hydrogen through electrolysis powered by renewables, the concept relies on natural subsurface processes that generate hydrogen within the Earth’s crust. Researchers at the US Geological Survey say the resource could be sustainable and environmentally useful if it can be found, assessed and managed responsibly, while laboratories including Idaho National Laboratory and Sandia have described it as potentially very low-cost if it can be produced at scale.
The U.S. Department of Energy has set a target of $1 per kilogram for clean hydrogen, and says that cost could be reached through a range of net-zero pathways over the coming decade. Its current estimate for geologic hydrogen is striking: less than $1 per kilogram in some scenarios, according to the figures cited by Oilprice.com. That would put it below the reported $3.50 to $6 range associated with present-day green hydrogen and potentially even undercut hydrogen made from fossil fuels.
The science, however, is still at an early stage. Geologic hydrogen forms through processes such as serpentinisation, when water reacts with iron-rich rocks, and through radiolysis, in which natural radiation splits water molecules. The challenge is not just locating deposits, but proving they can be extracted reliably, in sufficient volumes and without undermining the climate case that makes the fuel attractive in the first place.
Even so, the prospect is drawing attention because the industrial value proposition is unusually large. If geologic hydrogen can be commercialised, it could offer a cleaner and cheaper feedstock for heavy industry at a time when many planned green hydrogen schemes are struggling to move beyond announcements. For decarbonisation strategists, the appeal is obvious: a low-carbon molecule that may one day be available at a cost low enough to compete with incumbent fuels rather than subsidised alternatives.
For now, though, geologic hydrogen remains a promising frontier rather than a proven solution. The technology is still being tested, the resource base is still being mapped and the economics remain theoretical. But in a sector where cost has repeatedly stalled progress, the possibility of hydrogen produced from the Earth itself is enough to keep investors, researchers and policymakers watching closely.

- https://www.energy.gov/eere/fuelcells/hydrogen-production-pathways – The U.S. Department of Energy (DOE) is focused on developing technologies that can produce hydrogen at $2/kg by 2025 and $1/kg by 2030 via net-zero-carbon pathways. This is in direct support of the Hydrogen Energy Earthshot goal of reducing the cost of hydrogen by 80% to $1 per 1 kilogram in 1 decade. To reach these goals, the program looks at a wide portfolio of processes over a range of time frames. Currently, most hydrogen in the United States is produced by large-scale natural gas reforming without carbon capture and storage. This established technology has been shown to be able to reach the cost targets; however, the goal is to reach the cost target via low-carbon pathways. To produce hydrogen economically and via net-zero-carbon pathways, DOE supports the research and development of a wide range of technologies. In the near- and mid-term, electrolysis pathways (where electricity is used to split water into hydrogen and oxygen) are anticipated to begin reaching the cost targets. In the mid- to long-term, innovative approaches, such as those using waste streams and others based on solar energy, are expected to become viable.

This makes it attractive as an alternative to fossil fuels, which release carbon dioxide. Geologic hydrogen has the potential to be a sustainable and environmentally friendly energy source within the United States and around the world. The USGS Geologic Hydrogen Project conducts research on naturally occurring hydrogen across the nation and the world. The project provides critical scientific insight and data that support the discovery, assessment, and responsible management of geologic hydrogen resources. Research efforts are focused on understanding the natural processes that could lead to recoverable geologic hydrogen resources, as well as developing exploration tools and strategies that could assist in resource discovery and extraction. The goal is to improve our understanding of this previously unrecognized energy resource to help meet the nation’s future energy needs.

This ambitious goal seeks to make hydrogen more affordable, thereby expanding existing markets and creating new ones, including for iron and steel production, ammonia, heavy-duty trucking, and energy storage. The Hydrogen Shot is part of the DOE’s broader efforts to develop and deploy hydrogen technologies across multiple sectors, with the vision of enabling energy pathways that are interconnected and sustainable.
- https://www.nature.com/articles/s41560-024-01684-7 – A 2025 study published in Nature Energy examined the implementation of green hydrogen projects over a three-year period, tracking 190 projects. The study found that less than 7% of planned green hydrogen projects were completed on schedule, highlighting a significant implementation gap in the sector. The research underscores the challenges in scaling up green hydrogen initiatives and the need for more effective strategies to meet global decarbonization goals.
- https://inl.gov/integrated-energy/geothermal-energy/geologic-hydrogen/ – Geologic hydrogen forms within Earth’s crust through natural processes such as serpentinization, where water reacts with iron-rich rocks, and radiolysis, where natural radiation breaks down water molecules. This largely untapped resource is estimated to cost less than $2 per kilogram in the United States. The Idaho National Laboratory (INL) is at the forefront of exploring and developing innovative methods to locate and extract geological hydrogen, aiming to make it a reliable and affordable part of U.S. energy security.
- https://energy.sandia.gov/geologic-hydrogen/ – The estimated cost of geologic hydrogen is low ($0.5-1 per kg) compared to current industrial methods of producing hydrogen. These vital areas of research must be framed by a commonsense approach to the economics of making geologic hydrogen a reliable and affordable part of U.S. energy security. A key economic question is whether stimulated hydrogen can be produced in sufficient quantities to capture and drive industrial processes, thereby incentivizing private investment. While the cost of producing hydrogen from current methods is high, future geologic hydrogen production systems have the promise to become very competitive. The R&D approaches outlined earlier may incentivize private industry to invest in projects necessary vital to making geologic hydrogen an important part of our nation’s energy security.
