Will Regan

About

Will Regan, Ph.D., is the co-founder and President of Pacific Fusion, a Fremont, California-based startup founded in 2023 to deliver the world's most affordable, on-demand clean energy through pulser-driven inertial fusion—leveraging fast-rising high-current pulses to magnetically compress deuterium-tritium fuel targets, aiming for net facility gain (more fusion energy out than electricity in) by 2030 via a Demonstration System promising 1,000x better price-performance than NIF's laser approach. A UC Berkeley alumnus who previously catalyzed the private fusion boom as co-developer of ARPA-E's ALPHA program supporting low-cost plasma heating, Regan later led moonshot energy and climate projects at Google X—including founding Alphabet's Mineral agricultural tech division—before assembling Pacific Fusion's elite team of national lab veterans to rapidly prototype scalable systems amid a $900M+ milestone-based Series A from General Catalyst and others. A congressional witness on fusion's promise for U.S. energy leadership, prolific communicator on podcasts and technical papers, and advocate for pragmatic paths to gigawatt-scale power, Regan is driving an ambitious roadmap toward pilot plants in the 2030s to meet exploding demand from AI, electrification, and global prosperity.
