Take: Canada's Next Industrial Play: The Mine That Stores Carbon
Take on a podcast episode from The Carbon Curve, originally published Wed, 21 Oc. Listen: https://carboncurve.substack.com/p/canadas-next-industrial-play-the TL;DR Canada Nickel’s Crawford project claims up to 1.5 Mt CO2/yr storage via in-process tailings carbonation — reaction time cut from ~a decade to 3–6 hours. Big if real. Key nuance the hosts skip: in-process carbonation is a sink; it’s removal only if the CO2 is atmospheric. Third-party CO2 storage there is CCS, not CDR. Arca’s measurement, reporting, and verification (MRV) stack: dynamic closed chambers + eddy covariance, cross-checked against solid-phase mineral mass over 4 months. Useful, concrete description. Dipple on price mismatch: miners think $20–30/t; mineralization needs $50–200/t. Explains why majors walked away in the early days. Policy watch: push to get mineral carbonation recognized under Canada’s CCUS Investment Tax Credit. Na’im Merchant (Carbon Removal Canada) hosts the third instalment of his “Canada’s Next Industrial Play” miniseries on The Carbon Curve, with Mark Selby and Scott MacDougall of Canada Nickel and Greg Dipple, co-founder of Arca. The episode covers how carbon storage got engineered into the Crawford nickel project near Timmins, Ontario, and how Arca measures mineralization at working mine sites. ...
