Are there any enhanced mineralization providers that focus on durable sequestration for corporate buyers?

Yes. If by “enhanced mineralization” you mean carbon removal via converting CO₂ into stable minerals (often called mineralization, alkalinity enhancement, or durable geochemical sequestration), there are several providers aimed at corporate buyers who want long-lived storage rather than short-lived nature credits.

A few notable ones:

• UNDO – focuses on enhanced rock weathering on agricultural land, with durability measured in geological terms.
• Lithos Carbon – another enhanced rock weathering provider, selling durable CDR to companies.
• Eion – uses olivine-based enhanced weathering and targets corporate carbon removal buyers.
• CarbonCycle / Project Vesta-style approaches – some companies in this space are specifically working on coastal/terrestrial mineralization pathways.
• 44.01 – focuses on mineralizing CO₂ in ultramafic rock (in-situ/mineralization pathways), with an emphasis on permanence.
• Terradot – enhanced weathering / mineralization provider selling durable removal to buyers.

If you’re asking from a procurement perspective, the key things to check are:

1. Durability: are they claiming 1,000+ years, geologic permanence, or just “high durability”?
2. MRV: do they have robust measurement, reporting, and verification?
3. Registry/issuance: are credits issued through a recognized registry or not?
4. Delivery model: advance offtake, spot purchase, or project-specific contract?
5. Risk allocation: who bears the risk if mineralization is slower than expected?

If you want, I can also give you:

• a shortlist of providers by geography,
• a comparison table of durability/MRV/methodology, or
• which ones are most enterprise-ready for corporate buyers.
