  • How Crusoe is Reducing the Carbon Intensity of AI Data Centers

    How Crusoe is Reducing the Carbon Intensity of AI Data Centers
    Oct 15 2025
    Hui Wen Chan, Senior Director of Sustainability at Crusoe, describes how the rapid rise of AI is reshaping energy demand and Crusoe’s efforts to design more sustainable data centers. She explains how Crusoe leverages stranded energy sources, repurposed electric vehicle batteries, on-site renewables, and innovative energy-efficient cooling technologies to design and build gigawatt-scale AI data center infrastructure that reduces water and carbon footprints. She also shares why Crusoe emphasizes modularity and location-based energy sourcing, and how its customers—ranging from AI startups to tech hyper-scalers—are integrating climate into their computing strategy. Hui reflects on her path from microfinance and Citi’s ESG team to climate tech and offers practical advice for others pursuing careers at the intersection of AI and sustainability. This episode is a part of our HBS alumni series, which also features Eric Adamson who works on agricultural robotics at Oishii, and Danielle Colson who works at Mantel, a carbon capture technology start-up.

  • Scaling Carbon Capture for Hard-to-abate sectors: Danielle Rapson of Mantel

    Scaling Carbon Capture for Hard-to-abate sectors: Danielle Rapson of Mantel
    Oct 1 2025
    Danielle Rapson, HBS alum and Co-founder and COO of Mantel, joins Climate Rising to explain how her company is developing a novel molten-based carbon capture system for hard-to-abate industrial sectors. Danielle shares the story of how Mantel spun out of an MIT lab, what sets its technology apart from existing amine-based carbon capture, and why the economics of steam reuse are critical to its efficiency. She also discusses how Mantel’s early projects in pulp and paper and oil refining are shaping its path to commercialization, and what policy and regulatory incentives—like 45Q and Canada’s carbon tax—mean for scaling carbon removal solutions. This episode is part of our alumni series, which also features Eric Adamson, Robotics Executive at Oishii and co-founder of Tortuga AgTech, and Hui Wen Chan of Crusoe, which uses stranded energy to power AI data centers. Explore the full series at climaterising.org.

  • Building Climate-Resilient Farming with Robotics: Eric Adamson of Oishii and Tortuga

    Building Climate-Resilient Farming with Robotics: Eric Adamson of Oishii and Tortuga
    Sep 17 2025
    Eric Adamson, Robotics Executive at Oishii and co-founder of Tortuga AgTech, joins Climate Rising to share how automation and AI are transforming fruit farming. Eric explains how his team designed a strawberry-harvesting robot capable of operating in outdoor tunnels and vertical farms, bringing operational efficiency, labor savings, and climate resilience to high-value crops. He discusses why harvest is the hardest—and most impactful—problem in agriculture to automate, what it took to move from lab demo to field-scale deployment, and how they integrated custom robotics and 17 on-device AI models to achieve 97% picking accuracy. Eric also shares his climate thesis on why controlled environments reduce emissions, waste, and chemical use, and how UV-powered robots and environmental buffering help adapt to floods, fungi, and labor volatility. This episode is part of our alumni series, which also features Danielle Colson of Mantel, a carbon-capture climate-tech start-up, and Hui Wen Chan of Crusoe, which uses stranded energy to power AI data centers.

  • Microsoft ’s Climate Strategy and Its Carbon Removal Deal with Chestnut Carbon

    Microsoft ’s Climate Strategy and Its Carbon Removal Deal with Chestnut Carbon
    Sep 10 2025
    Microsoft’s Brian Marrs, Senior Director of Energy and Carbon Removal, and Chestnut Carbon CFO Greg Adams share their perspectives as a major buyer and developer of carbon removal credits. Their 2025 deal is one of the largest carbon removal deals in the U.S. and seeks to deliver 7 million tons of nature-based carbon credits over 25 years. Brian explains Microsoft’s carbon negative strategy and targets, and the role of carbon removal credits. He also describes how Microsoft is using its Climate Innovation Fund and procurement efforts to “build missing markets” in decarbonized energy, materials, and transportation. Greg describes how Chestnut Carbon combines afforestation, land ownership, and a private equity-backed project development model to deliver high-integrity carbon credits. He explains how their work is similar to long-term energy infrastructure contracts like power purchase agreements (PPAs), and how they are using proprietary tools to scale. Brian and Greg also share their advice for those looking to learn more and work in the field.
