    384: Graphyte's Strategy Is a Masterpiece of Simplicity—w/ Barclay Rogers & Hannah Murnen

    29/01/2026 | 57 mins.
    So many people think they need to dream up wild new tech to be successful at carbon removal. But one of CDR's most ascendent companies is relentlessly simple. They're so linear that I scrambled to make sure I wasn't missing something... In fact, if you've ever received coaching from me about simplicity, this is where I'm sending you from now on.
    I recently completed Noah Deich and Dr. Jen Wilcox's UPenn continuing education course, CDR Executive Education Program/Purchasing Carbon Removal Credits. It was wonderful and I highly recommend it.
    It did require a few homework assignments and a group project based upon a project developer. I chose Graphyte and their work putting waste biomass into bricks, wrapping them in polymer, and burying them underground. This is part of the class of projects called BiCRS (pronounced "bikers"), or Biomass Carbon Removal and Storage.
    Today's show has Dr. Hannah Murnen, Graphyte's CTO, and Barclay Rogers, Graphyte's Co-Founder and CEO, on to correct my homework from the course. I've never had a show quite like this.
    My sincere respect to each of them for digging into this with me and sharing their numbers. Not everyone in CDR is willing or able to do that, and I'm so happy we got to do that together.
    This show also inspired me to make an episode about linearity vs. holistic thinking in CDR. If one focuses on carbon efficiency, Graphyte makes so much sense. But are we optimizing only for solving climate change, or is this a polycrisis that requires a much deeper and interconnected approach? What you choose may say just as much about your values and how you perceive the problem. Stay tuned...

    Carbon efficiency is how much of the carbon remains after the source material has been converted into a form of carbon removal, e.g. Graphyte loses very little carbon back to the atmosphere between waste biomass, processing, and burial. Biochar has a lower carbon efficiency because more carbon is released during pyrolysis. It isn't the only factor that matters, but has major repercussions for calculating net removals and which project types are suitable for which goals.

    I had to dig to figure out where I got the Nintendo insight from, but it originates from Richard Rumelt's Good Strategy Bad Strategy: The Difference and Why It Matters.

    383: The Biochar Company Owned by a Data Center Company Owned by Private Equity—w/ Alastair Collier, A Healthier Earth

    20/01/2026 | 1h 2 mins.
    Are we thinking about biochar financial strategy all wrong? It's not often a good fit for venture capital, but is it actually a great fit for private equity? It might be, at least if you can get the ticket size big enough...
    Today's guest is Alastair Collier, Chief R&D Officer at A Healthier Earth, a biochar project developer that is a wholly-owned subsidiary of Pure DC, a data center project developer, who is supported by Oaktree Capital Management, a private equity firm (which in my understanding, does several other things beyond private equity.)
    Alastair explains how A Healthier Earth went down this road, why he's okay with giving up ownership of his company and accepting a management compensation plan rather than looking to a venture-backed exit, and why more biochar project developers should obsess over conventional business metrics rather than why biochar is going to save the world.
    Whether one wants to chart the same course or not, it's important for all those who work in carbon removal to know what kinds of deals are possible in what may prove to be a challenging 2026.
    Listen up, as Alastair has a lot of valuable advice to share in this one.

    382: Silicates vs. Carbonates: How the 1996 IPCC Report Created Enhanced Rock Weathering Path Dependency—w/ Dr. Tyler Kukla, CarbonPlan

    15/01/2026 | 59 mins.
    Some decisions we don't expect to have big consequences. And yet, sometimes you wake up thirty years later in a world deeply altered by that little moment. Today's show is about when that happens in science.
    Dr. Tyler Kukla is a Research Scientist at CarbonPlan, one of carbon removal's preeminent watchdog nonprofits. He returns to the show to explore how a conservative estimation of how much carbon returns to the atmosphere after agliming with carbonate rock (all of it) in the 1996 IPCC report has led us into a commercial carbon removal future that focuses almost entirely on silicate rock.
    This isn't a story about whether silicates or carbonates are better for enhanced weathering (it really depends upon a number of geographic factors and design decisions around system boundaries and additionality), but about how some good faith placeholders can reify to such an extent that they do so much more than they were ever expected to.

    381: Carbon Removal's False Peak as mapped by Noah Deich

    09/01/2026 | 53 mins.
    Life gotten harder recently? You must have just leveled up. We all thought we were doing the very hard work necessary to scale carbon removal, but was this ultimately a false peak? When you climb to what you think is the top of the mountain only to find a lot more mountain lurking behind it?
    Today's show is with Noah Deich, a carbon removal mover and shaker with his thumbprint on many of the biggest organizations and policies in the world. He recently completed a year in the prestigious Stripe Climate Fellows program, which selected a cohort of some of the sharpest people in CDR to develop new approaches to grow demand for carbon removal. Noah's effort was an attempt to create an Advance Market Commitment structure like Frontier but for governments rather than corporations. You'll hear how that went in this episode...
    Noah and host Ross Kenyon also laugh about the old days of commercial carbon removal, their mistaken beliefs (and maybe mostly Ross's), and try to chart a course forward for our crucial but incredibly trying work.

    380: Ezra Klein's Abundance vs. Paul Kingsnorth's Machine—Wizards & Prophets All the Way Down...

    02/01/2026 | 41 mins.
    The perennial fight returns... In one corner, there are the wizards: optimists who are betting that technology and economic growth can solve our problems faster than it can create them? In the other corner, prophets: who believe we have deeply lost in our way in ignoring limits and that we need to get ourselves back to the garden.
    How much wizard and how much prophet do you have contained in your own heart?
    Today's monologue episode has host Ross Kenyon exploring two recent books: Ezra Klein & Derek Thompson's Abundance, and Paul Kingsnorth's Against the Machine: On the Unmaking of Humanity, regarding how they continue the oldest and deepest fight in environmentalism.
