Our ultimate goal is simple: make clean energy available whenever and wherever it’s needed. As the world grapples with climate change and environmental degradation, the shift towards renewable energy has never been more critical. Innovative companies are at the forefront of this transformation, developing sustainable energy solutions that reduce carbon footprints and promote a greener future.

How are these companies driving the renewable energy revolution, and what impact are they making on the environment and the economy? As a part of this series, we had the pleasure of interviewing Hannan Happi. Hannan Happi is the CEO and co-founder of Exowatt. A mechanical engineer by training, Hannan studied at the Technical University of Munich and the Stanford Graduate School of Business. Before founding Exowatt, Hannan held leadership and engineering roles at General Electric, Siemens, Accenture, and Tesla.

He later co-founded and led Volansi, a vertical take-off and landing drone startup focused on autonomous logistics, which was acquired by a major defense firm. Now based in Miami, Florida, Hannan and the Exowatt team are focused on solving one of the most urgent infrastructure challenges of our time: delivering scalable, dispatchable, onsite energy solutions that keep pace with the digital world’s accelerating demands. Thank you so much for joining us in this interview series! Before we dig in, our readers would like to get to know you. Can you tell us a bit about how you grew up? I’m a mechanical engineer by training.

I grew up with a deep curiosity about how things work — which led me to study at the Technical University of Munich and eventually to roles at Siemens, where I worked on combined cycle power plant design, and then at General Electric on wind turbines. Energy infrastructure was in my DNA early on. Thirteen years ago, I made the leap to the United States to join Tesla, which was a transformative experience that shaped everything that came after. Can you share the most interesting story that happened to you since you began your career? Working on the original Model S at Tesla’s Fremont factory was a turning point.

Most of the industry thought EVs were a niche curiosity at the time. But being inside that factory — watching a fundamentally different kind of vehicle come to life — showed me how radically the world can shift when you commit to solving the right problem at the right moment. That experience planted something in me. Years later, when the energy crisis around AI infrastructure started coming into focus, the urgency felt familiar. So did the skepticism. And so did the opportunity to build something the world needs before it fully realizes it needs it.

That’s the through-line of my career, and it’s what brought me to Exowatt. Are you working on any exciting new projects now? How do you think that will help people? At Exowatt, we’re focused on one of the most urgent infrastructure challenges of our time: powering AI sustainably. Our system converts solar energy into stored thermal energy, which can then be dispatched as electricity whenever it’s needed — day or night, cloudy or clear.
