The World Intellectual Property Organization (WIPO) has published a feature on Carbfix, the Icelandic company whose carbon capture and storage (CCS) technology permanently converts injected CO2 into solid carbonate rock underground. The profile, which appears on the UN agency's news platform, marks a notable institutional checkpoint for a storage method that has moved from field experiment to a patented, licensable industrial process.

The technology itself works on a simple geological premise. Operators dissolve captured CO2 in water and inject the solution into basalt formations. There, the dissolved carbon reacts with calcium, magnesium and iron in the rock and mineralizes into carbonates — effectively turning the greenhouse gas into stone within the subsurface. Unlike conventional geological storage, which traps CO2 as a supercritical fluid in sedimentary reservoirs and depends on caprock integrity to prevent migration, mineral storage locks the carbon into the rock matrix itself.

That distinction matters for permitting. A storage site that mineralizes its CO2 removes the long-term leakage question that dominates regulatory review of conventional storage projects, and it does so on a timescale that shortens the monitoring obligations regulators typically attach to injection licenses. WIPO's decision to profile the company places the process squarely in the intellectual property conversation: the method has been patented, and the company licenses it to project developers outside its home market.

For the circular economy desk, the relevant material stream is water and basalt rather than metal or polymer. Carbfix's core process requires substantial water to dissolve the CO2 before injection — roughly the order of 25 tonnes of water per tonne of CO2 in its Icelandic operations, with seawater injection under development for water-constrained sites. The feedstock is captured CO2 from point sources, which positions the technology downstream of capture plants at geothermal stations, industrial emitters and, prospectively, direct air capture facilities.

The company grew out of research at Reykjavik's University of Iceland and the geothermal operator Reykjavik Energy, with the first injections carried out at the Hellisheidi geothermal power plant. What began as an experiment in disposing of geothermal CO2 and hydrogen sulfide has since developed into a commercial offering, with the company marketing its injection services to emitters seeking permanent storage and running projects beyond Iceland's basalt fields.

WIPO's interest signals where the agency sees the technology sitting in the broader innovation picture. Carbon removal and storage has become one of the fastest-growing filing areas in clean technology patents, and mineralization storage is a distinct claim family within it. A UN IP agency profiling a single SME-stage operator suggests the process is now treated as a reference case: a Nordic research spin-out that converted publicly supported pilot work into a defensible patent position and a licensing model.

The competitive question for Carbfix and its licensees is cost per tonne stored. Mineralization carries energy and water penalties that conventional sedimentary-basin storage avoids, and it competes against a pipeline of depleted oil and gas reservoir capacity that incumbent operators can permit at lower unit cost. Its counter-argument is permanence and monitoring liability: a tonne converted to carbonate carries no post-closure stewardship burden comparable to a tonne held as a buoyant fluid beneath a caprock.

Watch the permitting docket and the licensing ledger. The milestone that decides what happens next for this storage route is not the WIPO feature but the number of injection permits granted to Carbfix and its licensees in basalt provinces outside Iceland, and the contracted volumes of CO2 those projects commit to mineralize on dated deadlines.
