Re-Engineering Chemical Production for Carbon Dioxide Removal with Dr. Laura Lammers, Founder and CEO of Travertine

Hardware to Save a Planet · 24 Nov 2022 · 33m · Episode 14

What this episode covers

Dr. Laura Lammers, Founder and CEO of Travertine, explains how her company uses water electrolysis to upcycle sulfate waste (like phosphogypsum) into carbon-negative sulfuric acid while permanently sequestering CO2 in carbonate minerals. She discusses the massive scale of industrial sulfate waste, the business case for fertilizer and mining customers, and the hardware challenges of scaling electrolyzers with divalent ions. Lammers also outlines the path to gigaton-scale carbon removal through enhanced weathering and the impact of the Inflation Reduction Act on green hydrogen and carbon credits.

    Literally unearthing a climate solution with Cody Finke of Brimstone

    Cody Finke, co-founder and CEO of Brimstone, explains how his company is decarbonizing cement production by replacing limestone with calcium silicate rocks like basalt. He details the chemical process that eliminates process emissions and creates a magnesium byproduct that passively sequesters CO2, making the material carbon-negative. Finke discusses the strategic pivot from developing novel materials to producing ordinary Portland cement to ensure rapid adoption by the construction industry, and outlines the path from lab validation to pilot plants and eventual commercial scaling.

    Building a decarbonization army with Shashank Samala of Heirloom

    Shashank Samala, co-founder and CEO of Heirloom, explains how his company built North America’s first operational direct air capture facility in Tracy, California, using a novel limestone-based process to remove CO2 from the atmosphere. Samala details the technical approach of baking limestone into calcium oxide to create 'trays' that absorb CO2, contrasting this with expensive synthetic materials used by competitors like Climeworks. He discusses the business model, noting that Heirloom sells carbon removal credits to major corporations like Microsoft, Stripe, and Meta, aiming to scale production to 1 million tons per year by leveraging the Inflation Reduction Act’s 45Q tax credits. The episode covers Heirloom’s journey from a garage-stage startup to scaling production, highlighting their goal to build 1,000 facilities globally to remove 1 billion tons of CO2 annually by the 2030s.

    ICYMI... HIBT Lab! Climeworks: Jan Wurzbacher

    Jan Wurzbacher, co-founder and CEO of Climeworks, explains how his company is building the world's largest direct air capture facility, the Orca plant in Iceland, which removes 4,000 tons of CO2 annually. He details the technology's modular design, using filter materials that capture CO2 and release it when heated, allowing for permanent underground storage in basaltic rock. Wurzbacher discusses the company's journey from selling CO2 to greenhouses and Coca-Cola to securing $650 million in Series 6 funding to scale operations. He argues that while emission reductions are critical, removing 10 billion tons of CO2 yearly by 2050 requires scalable technological solutions like Climeworks, which he compares to the rapid cost reduction seen in solar PV.

    HIBT Lab! Climeworks: Jan Wurzbacher

    Jan Wurzbacher, co-founder and CEO of Climeworks, explains how he and co-founder Christoph Gebald built the world’s largest direct air capture facility, the Orca plant in Iceland, which removes 4,000 tons of CO2 annually. Wurzbacher details the company's evolution from selling captured CO2 to Coca-Cola and greenhouses to providing permanent carbon removal services for corporate clients like Microsoft and private individuals. He discusses the massive scaling challenges, including the need for 10 billion tons of annual removal by 2050, the capital intensity of hardware, and the strategic importance of pairing capture facilities with renewable energy sources like geothermal power.

    Fixing cement’s carbon problem

    Leah Ellis, co-founder and CEO of Sublime Systems, explains how her company uses electrochemical processes to produce cement at room temperature, avoiding the high-temperature kilns and limestone decomposition that cause 8% of global emissions. Shayle Khan of Energy Impact Partners discusses the limitations of current decarbonization strategies, including supplementary cementitious materials like fly ash and post-combustion carbon capture, highlighting why they offer only incremental reductions. The conversation covers the technical properties of Portland cement, the centralized nature of cement production versus the distributed ready-mix market, and the economic argument that low-carbon cement's 'green premium' is negligible compared to total construction labor costs.
