Using Ocean Alkalinity Enhancement for Carbon Removal with Mike Kelland, CEO of Planetary

Hardware to Save a Planet · 6 Jul 2023 · 45m · Episode 30

What this episode covers

Mike Kelland, CEO of Planetary, explains how his company uses Ocean Alkalinity Enhancement (OAE) to remove CO2 by processing mine tailings into magnesium hydroxide, which is then dosed into the ocean to neutralize acidity and sequester carbon. He details the technical process involving electrolysis, the critical role of MRV (Measurement, Reporting, and Verification) using sensors from partners like Dartmouth Ocean Technologies and RBR, and the business model focused on selling carbon removal credits. Kelland discusses the challenge of scaling to a gigaton target by 2045, emphasizing the need to design for massive physical scale from the start to avoid bottlenecks in energy and waste management.

    What climatetech can learn from the oceans

    Alissa Peterson, co-founder and executive director of SeaAhead, discusses the intersection of blue tech and climate tech, focusing on decarbonizing shipping through alternative fuels like ammonia and methanol, and expanding offshore wind innovation beyond turbines to cable protection and biodiversity. She details emerging carbon removal strategies, including sinking kelp and ocean alkalinity enhancement using olivine, while highlighting the critical scientific gaps in measurement, verification, and permanence (MRV). Peterson emphasizes that while permitting is difficult, targeted innovation can mitigate ecosystem impacts, arguing that the sector must avoid the boom-bust cycles of previous clean tech waves by securing rigorous science and sustainable business models.

    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.

    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.

    The challenges of building a carbon removal portfolio

    Stacy Kauk, Head of Sustainability at Shopify, details the company's $55 million investment in 85,000 tons of durable carbon removal, explaining how they manage a venture-capital-style portfolio of early-stage technologies. She highlights the significant delays in credit delivery caused by permitting hurdles, technological pivots, and the infancy of Measurement, Reporting, and Verification (MRV) methodologies. Kauk argues that while the market aims for a standardized commodity, current buyers must support a diverse mix of engineered systems like Direct Air Capture (DAC) and natural system enhancements like ocean alkalinity to discover viable cost curves and scalability.

    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.
