AI-Generated Summary

Updated January 6, 2026 at 6:50 AM UTC

The Office of Fusion Act of 2025 amends the Department of Energy Organization Act to establish a dedicated Office of Fusion within DOE. The Office is tasked with advancing both near‑term and long‑term fusion research, development, and commercial deployment to strengthen U.S. energy security and economic competitiveness. It will consolidate existing fusion programs, work closely with the private sector and other federal entities, and report regularly to Congress on progress toward building commercial fusion power plants.

Key Provisions

  • Creates a new Office of Fusion within the Department of Energy, led by a Director appointed by the Secretary.
  • Sets the Office’s goals to boost U.S. energy and economic security, maintain leadership in fusion technology, and accelerate the development and commercial deployment of fusion power plants, aiming for construction of at least one private‑sector plant by Dec. 31, 2028.
  • Transfers all fusion‑related programs currently managed by the DOE Office of Science’s Fusion Energy Sciences program to the new Office and requires a timeline for that transfer.
  • Requires the Secretary and the Office Director to submit a commercial deployment roadmap to Congress within one year, and to update it every four years (or with another periodic energy report).
  • Mandates coordination with private industry, national labs, universities, and other federal agencies to avoid duplication and to support a national fusion supply chain, workforce development, and international cooperation.
