Fusion Gets Real: Will Regan on Pacific Fusion’s Path to Clean Firm Power
Fusion has spent decades sitting just beyond the horizon. But according to Will Regan, Founder and Chief Scientist at Pacific Fusion, that story is changing fast.In this episode of Green Giants: Titans of Renewable Energy, host Wes Ashworth, President of Lee Group Search, sits down with Will to explore why fusion is moving from a distant scientific promise into a practical race around execution, manufacturing, modularity, and real-world clean energy infrastructure.Will brings a rare perspective to the fusion conversation. Before co-founding Pacific Fusion, he served as an ARPA-E Fellow, spent more than seven years at X, Alphabet’s moonshot factory, and helped create the original vision and team behind Mineral. Today, he is helping lead Pacific Fusion’s effort to commercialize pulsed magnetic inertial fusion, a pathway designed around modular pulser systems, compact chambers, and simplified fusion targets. The conversation breaks down fusion in plain English, including why it has the potential to deliver abundant, clean, firm power with low land and material requirements. Will explains how Pacific Fusion’s approach differs from laser-driven inertial fusion and magnetic confinement systems, and why recent breakthroughs at Lawrence Livermore National Laboratory, Sandia National Laboratories, and in pulsed-power hardware helped make 2023 the right moment to build a company around this pathway. A major theme throughout the episode is that fusion progress cannot be judged by vague headlines alone. Will walks through a more useful scorecard, from scientific proof of concept to scientific gain, net facility gain, power gain, and ultimately affordable power. Pacific Fusion’s stated near-term objective is net facility gain by 2030, meaning more fusion energy out than the total stored energy input to the machine. Wes and Will also dig into the industrial reality behind commercial fusion: why modularity matters, why targets can make or break the economics, what it takes to move from one successful fusion shot to repeatable infrastructure, and how a future fusion plant could fit into the grid as clean firm power alongside solar, wind, storage, geothermal, hydro, and nuclear fission.This episode is a grounded look at one of the most ambitious frontiers in energy, without the hype. Fusion may still face major challenges in repetition, durability, supply chains, fuel, workforce, and cost. But the opportunity is enormous: clean, reliable, high-density energy that could reshape what is possible for the grid, industry, and global abundance.In this episode, we cover:Why fusion is entering a new chapter focused on executionHow Pacific Fusion’s pulsed magnetic inertial fusion approach worksWhat the 2022 NIF and Sandia breakthroughs changedWhy modular pulser systems could matter for cost and scaleThe difference between ignition, scientific gain, net facility gain, and power gainWhy Pacific Fusion is targeting net facility gain by 2030How fusion could support clean firm power and real grid reliabilityWhy fusion will need engineers, technicians, tradespeople, and builders, not just PhDsWhat a future of abundant clean energy could unlockLinks: Will Regan on LinkedInPacific Fusion's WebsiteWes Ashworth: https://www.linkedin.com/in/weslgs/Email: wes@leegroupsearch.comhttps://leegroupsearch.com/green-giants-podcast/https://leegroupsearch.com/
