Pacific Fusion, a California-headquartered startup founded in 2023, is constructing a billion-dollar fusion machine in New Mexico with the ambitious goal of achieving "net facility gain" by the end of the decade. This benchmark signifies the machine generating more energy than it consumes, a crucial step towards limitless clean energy. The company, which has raised over $1 billion in private capital, plans to use immense pulses of electricity to compress hydrogen fuel capsules, with its demonstration facility designed to use 80 megajoules of electrical energy to charge capacitors for each pulse and yield approximately 100 megajoules of fusion energy, representing a net gain.
Beyond energy production, the facility will also be used for research on the country's aging nuclear warhead stockpile, a dual-purpose approach that leverages the pulsed-power technique's ability to create extreme states of matter for high-energy-density science. This collaboration with Sandia National Laboratories for both energy and weapons applications underscores the strategic importance of Pacific Fusion's work. The company's technology, which efficiently converts electrical charge to target compression, is seen as more energy-efficient than laser-based fusion approaches like the National Ignition Facility (NIF), which achieved ignition but not net facility gain due to significant energy losses.
The push for advanced fusion technology comes amid a global race, particularly with China, which is heavily investing in its own fusion infrastructure. While the U.S. has seen significant private investment in fusion, totaling over $14 billion across dozens of startups in the past five years, China is also pouring billions into its fusion projects. Pacific Fusion's chief technology officer, Keith LeChien, emphasizes the urgency of U.S. investment to maintain leadership in this critical capability, highlighting the potential for high-yield, high-gain fusion within this decade as a strategic advantage.
