What was developed or tested
Mineralogy, carbonate formation, pore-water chemistry and field flux measurements underpin the work; handling can expose fresh reactive surfaces.
What the evidence supports
A globally significant Australian natural-laboratory case. Passive uptake is observed; the challenge is to increase rate while proving additionality and permanence.
Environmental and technical uncertainty
Mineral storage is potentially durable and may aid stabilisation, but MRV, water chemistry, dust and acceleration energy must be included.
Benefit-case screening lens
Potential value: Durable carbon removal, possible carbon value, improved residue stability and a measurable decarbonisation contribution.
Deployment constraints: Additional uptake, kinetics, measurement and verification, energy, water, land, operating integration and the permanence of storage.
Question before applying elsewhere
Can additional, durable carbon uptake be measured and verified without creating unacceptable energy, water or environmental burdens?
