    The soaring energy demands of AI-driven data centers have the entire industry searching for innovative solutions. To address this, Exowatt's P3 simplifies how energy is created, stored, and used: ☀️ Power: The P3 captures and concentrates solar heat. 🔥 Preserve: It then stores energy as thermal heat. ⚡️ Provide: Finally it converts stored heat to electricity on demand. It's like having a solar-powered generator that can save energy for later use, making it ideal for meeting the massive, constant power needs of AI-driven data centers. CEO Hannan P. and Cody discuss Exowatt's solar-powered approach to data centers on Inevitable. Listen wherever you get podcasts.

    We often assume batteries are inherently good for the energy transition—but what if that's not the case? 🪫 This week, Jacob Mansfield, CEO of Tierra Climate, dives into a surprising truth: grid-scale batteries can actually increase emissions. 🤔 Why? A combination of efficiency losses, misaligned market signals, and a lack of incentives. But there’s hope — Jacob outlines actionable solutions, from updating carbon accounting standards to creating market mechanisms like carbon offsets for batteries. These steps can transform energy storage into the decarbonization hero it’s meant to be. Read more in this edition of the MCJ Newsletter.

    The carbon removal industry often focuses on two big questions: which tech works, and who pays for it? But it’s not just about tech or financing. We need clarity on methodology, net-negativity, land use, permits, and funding before selling carbon credits at scale. As the ecosystem grows, organizations like Isometric, CarbonPlan, Enduring Planet and AirMiners are paving the way forward. Read Jamie Wong’s op-ed, "For Sale: A Promise to Remove Invisible Gas," in this earlier edition of the MCJ newsletter for the full story.
