Details
- Google DeepMind has partnered with Commonwealth Fusion Systems (CFS) to deploy artificial intelligence in advancing fusion energy, focusing on CFS’s SPARC tokamak project, which aims to achieve net fusion energy.
- The partnership targets three major technical areas: rapid, differentiable plasma simulation; identifying optimal pathways for maximizing fusion energy; and developing reinforcement learning for real-time control of plasma stability and heat management at extreme temperatures.
- As part of the collaboration, they have released TORAX, an open-source plasma simulator built with JAX, enabling researchers to conduct millions of virtual experiments to accelerate discoveries.
- CFS recently raised $863 million in Series B2 funding in August 2025 and has secured approximately $3 billion to date, further supporting development of its fusion initiatives, with SPARC’s start expected in late 2026 and breakeven anticipated by 2027.
- Google has not only invested in CFS but also agreed to purchase half the power output from the company's forthcoming ARC power plant in Virginia, which aims to supply the grid by the early 2030s.
Impact
This collaboration between Google DeepMind and CFS highlights a significant leap forward for commercial fusion energy, uniting advanced AI with next-generation hardware. By optimizing operations and accelerating experimental cycles, this initiative could dramatically shorten the timeline to clean, sustainable fusion power. As hyperscale tech companies seek reliable energy for their growing AI demands, such partnerships may set a new pace for the global energy transition.
