Ohio has enacted legislation that establishes a framework for carbon capture and sequestration (CCS) activity within the state, farmanddairy.com reported. The new law addresses pore-space ownership and assigns the state a defined regulatory role for underground CO2 storage.

What does the law cover?

The statute creates a pathway for operators to seek authorization for permanent geologic storage of CO2 captured from industrial point sources. Until now, developers considering in-state sequestration operated without explicit statutory cover, limiting the kinds of binding storage agreements they could sign with emitters.

Why does the law matter for upstream and downstream operators?

Industrial emitters across Ohio — ethanol plants, ammonia producers, steel works, refineries, and natural gas processing facilities — generate concentrated CO2 streams that are candidates for capture. Without a defined in-state sequestration pathway, those operators have had to either rely on the federal UIC system or arrange to ship CO2 across state lines.

The new framework offers a third option: capture, transport, and permanent storage entirely within Ohio's borders. That option carries cost implications — pipeline buildout, monitoring wells, and verification protocols all add to the bill — but removes some of the permitting uncertainty that has stalled negotiations between emitters and sequestration developers.

What does the framework mean for project economics?

Developers have consistently flagged pore-space ownership as a precondition for any multi-year storage agreement with emitters. Storage contracts typically extend 10 to 30 years and require the operator to assume long-tail liability for injected volumes. Without statutory clarity on who owns the subsurface pore space and who can grant access to it, banks and offtakers have refused to underwrite the storage commitment.

The new law gives developers a documented chain of title to work from and gives mineral owners a clear set of rights they can monetize. That, more than the CO2 capture technology itself, has been the gating item on many of the projects announced across the Midwest in the past three years.

What is the federal context?

Class VI injection wells used for permanent geologic sequestration fall under the U.S. Environmental Protection Agency's Underground Injection Control (UIC) program. States can apply to assume primacy, meaning they would issue and enforce permits in place of the EPA, provided their regulatory programs meet federal standards. Ohio's framework would need EPA sign-off before the state could issue Class VI permits directly.

Where could storage anchor?

Appalachian Basin geology has drawn interest from sequestration developers. The Mt. Simon Sandstone and other deep saline formations underlying parts of Ohio have been the focus of characterization work. Wells drilled for unconventional oil and gas development in the Utica and Point Pleasant formations have generated subsurface data that developers use to identify candidate storage zones, confining layers, and pressure response.

What's the watch item?

The pace at which the Ohio Department of Natural Resources finalizes implementing regulations, the EPA's review timeline for any primacy application, and the first commercial project's final investment decision will determine whether the law produces operating facilities. Without an anchor emitter, a signed transport agreement, and a closed pore-space lease, projects will remain at the appraisal stage.

The framework places Ohio among states that have moved to formalize CCS — a list that includes North Dakota, Wyoming, Louisiana, and Indiana. The competitive test will be whether the regulatory pace keeps up with what developers say they need to commit capital.
