Industrial heat causes 20% of global greenhouse gas emissions — and almost nobody's working on the easy part. James Macnaghten is a Cambridge-trained engineer with 20+ patents who shut down his first energy storage company after realizing it's often cheaper to throw renewable energy away than store it. Now as CEO of Caldera, he's converting cheap electricity into industrial steam using recycled aluminum and volcanic rock — and deploying units into hospitals and factories without requiring grid upgrades.
James breaks down why the energy world keeps chasing steelmaking and cement while ignoring brewing, food, and pharma. He makes the case for hybridization over going 100% clean, shares why he thinks oil demand is headed for a crash, and questions whether the AI energy boom can survive its own economics.
