Commonwealth Fusion Systems (CFS) is on a mission to deliver clean fusion energy to the planet fast enough to matter for humanity’s biggest challenges. It’s urgent. The gap between the energy we need and the energy we have is widening every day. Fusion is a critical part of the energy transition away from fossil fuels, a new chapter for the world’s energy supply. We’re committing to delivering fusion power plants and a full-fledged fusion energy industry as we’ve delivered on other promises. Like the world’s strongest high-temperature superconducting magnet, the game-changing technology that’s making commercial fusion energy a reality. We’ve raised over $2 billion in capital — more than any other fusion energy company — and attracted top talent to design, build, and deliver commercial fusion power plants. And we’re working with policymakers and suppliers to make fusion energy available globally. As we push toward the fusion-energy future, we’ll keep setting and meeting milestones, sharing and validating our progress, and encouraging others to do the same.
