Minnesota Nears a Natural Hydrogen Crossroads

Minnesota must finalize natural hydrogen drilling rules by May 2026, a deadline that could open or delay a major US clean energy frontier

26 Mar 2026

Billions of years ago, the Midcontinent Rift System cracked open the earth beneath what is now Minnesota's Iron Range. Ancient iron-rich rocks and deep water may have spent that time quietly producing hydrogen. Whether anyone gets to drill for it now depends on what legislators do before May.

The state's Department of Natural Resources faces a statutory deadline to finalise permitting rules for natural hydrogen exploration by May 2026. Minnesota's legislature laid the groundwork two years ago, amending gas statutes to include naturally occurring hydrogen and giving the DNR authority to issue permits. A multi-agency committee followed, backed by more than $3.1m in state funding, and submitted a proposed temporary framework to lawmakers in January 2025.

The procedural stakes are unusually binary. If the legislature adopts the temporary framework, companies may begin applying for permits while full rulemaking continues. If it does not, a moratorium on gas production permits stays in force until rulemaking concludes, with May as the statutory hard stop. There is no middle ground.

The US Geological Survey ranks the Midcontinent Rift among the country's two most promising zones for naturally occurring hydrogen. Koloma, a leading explorer in the corridor, has already outlined plans for seismic surveys in Minnesota this year, a necessary step before any well is drilled, if permits materialise in time.

The race is not only geological. Global investment in natural hydrogen has passed $1bn, and regulatory activity is accelerating across Iowa and Kansas. Jurisdictions that establish clear rules early are drawing exploration capital. Those that do not are watching it move on.

Minnesota's May deadline is, in that sense, less a bureaucratic formality than a strategic choice. Whether the state emerges as an early mover in geologic hydrogen, or as a cautionary note about regulatory hesitation, is now largely a matter of legislative timing.
