Take: Carbon removal that utilities actually want
Take on a podcast episode from The Carbon Curve, originally published Wed, 05 Au. Listen: https://carboncurve.substack.com/p/carbon-removal-that-utilities-actually TL;DR CREW Carbon doses calcium carbonate into wastewater bioreactors, converting microbe-generated CO2 into stable bicarbonate — durable removal inside a closed, metered system. Just signed a Microsoft offtake for up to 23,602 durable removal units; total book now >$40M with JPMorgan, Google, Autodesk, Stripe/Frontier. Pitch to utilities is capex deferral + easier nitrogen/phosphorus compliance — CDR revenue is upside, not the core sell. Useful framing. measurement, reporting, and verification (MRV) story leans on the closed reactor: mass-balance and effluent chemistry, not open-ocean modeling. Materially stronger than marine ocean alkalinity enhancement (OAE) on measurement. Regulated-utility sales cycles are the real bottleneck, not chemistry. Worth taking seriously. The Carbon Curve’s Na’im Merchant hosts Joachim Katchinoff, CEO of CREW Carbon, on turning municipal wastewater treatment plants into alkalinity-enhancement sites. The episode was taped before CREW’s Microsoft deal dropped, so the show notes carry the news; the conversation itself is about mechanism, MRV, and how you actually sell CDR into a regulated utility. ...
