Koloma Geological Hydrogen Funding, $245.7 M Raised, Mitsubishi Partnership, and 16 U.S. DOE Projects (2021 to 2026)

Geological Hydrogen Commercial Projects, Koloma and Gold Hydrogen Lead Drilling Efforts

The geologic hydrogen sector has transitioned from theoretical modeling and small-scale proofs-of-concept to active, venture-backed commercial drilling aimed at proving scalable resource extraction. This shift marks a critical move from assessing whether the resource exists to determining if it can be produced economically. The success or failure of these initial commercial wells will dictate the industry’s near-term growth trajectory and its ability to attract large-scale capital.

• Between 2021 and 2024, the industry’s primary commercial datapoint was the small-scale Hydroma project in Mali, which served as a proof-of-concept by using naturally produced hydrogen to power a local village. During this period, activity was largely confined to academic studies and early-stage exploration by a few private pioneers.
• A significant acceleration occurred from 2025 to today, with well-funded startups launching ambitious drilling campaigns. Koloma is now actively drilling in Idaho, and Australia’s Gold Hydrogen has reported high-purity results from its Ramsay 1 and 2 wells, shifting the market’s focus from discovery to commercial viability.
• The emergence of “stimulated” hydrogen concepts, led by companies like Vema Hydrogen and Geo Kiln, introduces a strategic hedge against pure exploration risk. This approach aims to create hydrogen in-situ by injecting fluids into favorable rock formations, potentially offering a more predictable production method.
• Government support has become a key enabler. The U.S. Department of Energy (DOE) allocated $20 million across 16 research projects to advance exploration and production, while Michigan’s Executive Directive No. 2026-1 signals state-level commitment to building a commercial framework for the industry.

US and Australia Emerge as Key Hubs, Koloma and Gold Hydrogen Drive Exploration

Geologic hydrogen exploration is geographically concentrated in regions with favorable geology and supportive policy. The United States and Australia have emerged as the primary commercial hotspots, driven by targeted government resource mapping, new state-level policy initiatives, and promising early drilling results that have attracted significant international investment.

• From 2021 to 2024, exploration activity was sparse and globally scattered. Key locations included Mali (Hydroma’s operational well), Australia (Gold Hydrogen’s initial work on the Yorke Peninsula), and early-stage drilling in the U.S. Mid-Continent Rift system by Natural Hydrogen Energy LLC.
• The release of the U.S. Geological Survey’s (USGS) prospectivity map in January 2025 was a major catalyst for the industry. It provided a data-driven framework that focused U.S. exploration efforts on high-potential zones in the Great Lakes, Rocky Mountains, and specific areas on the East Coast.
• Since 2025, the U.S. has experienced a surge in targeted activity. Koloma is actively pioneering drilling in Idaho, Hy Terra is pursuing its project in Kansas, and the state of Michigan issued Executive Directive No. 2026-1 to formally prepare its regulatory environment for a geologic hydrogen industry.
• Australia remains a key global player, with Gold Hydrogen’s Ramsay wells confirming high purity levels. This success was instrumental in attracting a $9.54 million investment from Japanese industrial giants Toyota and Mitsubishi in 2025, validating the region’s commercial potential.

Technology Validation, Koloma and Hy Terra Drilling Moves from Theory to Practice

Geologic hydrogen technology is rapidly advancing from theoretical science and resource mapping to the critical pilot and validation phase. The primary challenge has shifted from proving the science of natural hydrogen formation to engineering reliable extraction methods and demonstrating commercially viable flow rates from drilled wells, a hurdle the industry must clear to scale.

• The 2021-2024 period was defined by establishing the scientific basis, primarily through serpentinization and radiolysis theories, and repurposing exploration tools from the oil and gas sector. The Mali well served as the only, albeit small-scale, real-world production example.
• Since early 2025, the industry has entered a new phase of active drilling and technology validation. The success of exploration now hinges on proving that hydrogen accumulates in large, high-pressure, extractable reservoirs, a critical unknown that current drilling by Koloma seeks to answer.
• Promising discoveries provided crucial validation and spurred investment. In late 2023, Gold Hydrogen reported purity up to 86% from its Australian well, while a deep drill hole in Finland detected concentrations up to 46% in 2024.
• A recent technological shift is the focus on stimulated production. This approach, pursued by Geo Kiln in partnership with Hy Terra, represents a parallel path to commercialization that could bypass the high risks of pure exploration by engineering hydrogen resources on demand.

SWOT Analysis, Koloma Cost Disruption Potential vs. Exploration Uncertainty

The strategic outlook for geological hydrogen is defined by the immense opportunity of its projected sub-$1/kg production cost, which is counterbalanced by significant weaknesses in geological understanding and the external threat of competing clean energy pathways. Recent drilling and investment have validated the potential but have not yet resolved the core exploration risks.

• If companies like Koloma and Gold Hydrogen can demonstrate sustained, commercially viable flow rates from their current pilot wells, watch for a rapid influx of capital from major energy corporations and a potential pivot away from more expensive green and blue hydrogen projects for certain applications like heavy transportation.
• The key signal to monitor is not just the discovery of hydrogen, which is now well-established, but the publication of verifiable data on flow rates, purity, and projected reservoir size. This data is the primary hurdle between exploration and bankability.
• A parallel indicator to watch is the progress of stimulated hydrogen pilots from firms like Hy Terra and Geo Kiln. Success in these engineered projects would provide a crucial fallback, mitigating the risk of pure exploration and offering a more predictable path to production.
• The establishment of clear regulatory frameworks, as initiated by Michigan’s 2026 directive, is a leading indicator of government confidence. The speed at which other jurisdictions follow suit will be essential for scaling the industry beyond initial pilots.
