Reichelstein frames Vaulted as a waste management company first, CDR second; gets paid on the disposal side, which sidesteps biomass-competition risk entirely. The Microsoft ~5M-tonne offtake (signed 2024) underwrites site development through ~2040 — the deal that turned them from operator into builder. Most of the conversation is leadership philosophy, not technical. Useful if you’re a founder; thinner if you came for measurement, reporting, and verification (MRV) or geology specifics. Spin-out mechanics from Advantek get a rare honest treatment — including why venture-backed spin-outs are scarce. Ross Kenyon hosts Julia Reichelstein, co-founder and CEO of Vaulted Deep, for a wide-ranging conversation that’s roughly one-third Vaulted operations and two-thirds founder psychology. If you’ve heard Reichelstein on the technical circuit before, this is the softer cut — useful for understanding how she thinks, less useful if you want to interrogate the deep-well injection thesis. ...

Take on a podcast episode from Reversing Climate Change, originally published Thu, 07 Ma. Listen: https://podcasters.spotify.com/pod/show/reversingclimatechange/episodes/398-Scientists-vs--Engineers---the-Commercial-Pressure-on-Carbon-Dioxide-Removalw-Erica-Dorr--Samara-Vantil--Rainbow-e3j0jq0 TL;DR Rainbow’s head of science Erica Dorr and certification engineer Samara Vantil reframe the science-vs-engineering split as a false binary; both do applied work daily. The real gap is technical-vs-commercial. Useful framing for anyone who’s watched a salesperson promise a methodology change on a call. Concrete example: biochar lab samples cost ~€600 to ship Africa→Europe. That’s the kind of number that should anchor measurement, reporting, and verification (MRV) requirement-setting. Defense of Charm’s “cut scope” posture as courage, not laziness — diminishing returns on the last sample are real and worth saying out loud. When project developers can’t deliver a data point, Rainbow’s default is a conservative discount factor, not rejection. Worth knowing if you’re a buyer reading their credits. Ross Kenyon hosts Erica Dorr (head of science) and Samara Vantil (environmental engineer, certification) of Rainbow, the carbon removal standard and registry. The episode is a follow-up to two essays Kenyon wrote for Rainbow on whether durable CDR needs more field engineers or more scientists, and lands somewhere more interesting than either piece: the science/engineering line is fuzzy, and the harder boundary is between technical teams and commercial. ...
