Global nuclear fusion technology development

Overview

The nuclear fusion sector is transitioning from theoretical physics toward industrial application, driven by significant global investment from both state and private sources. While the United States and China currently lead the market, European startups are working to secure technological leadership through specialized hardware and software solutions. In Europe, Munich-based Proxima Fusion is partnering with the government of Lower Saxony to establish a factory for high-temperature superconductor (HTS) tapes, essential for fusion reactor electromagnets. This project, involving approximately 140 million euros through 2029, aims to secure the European supply chain. Meanwhile, Lausanne-based Fusionality is developing AI-driven control systems to manage complex plasma conditions.

In the United Kingdom, the STEP Fusion programme is advancing toward the preliminary design phase for a prototype power plant at the former West Burton Power Station site in Nottinghamshire. UK Fusion Energy Ltd has invested nearly £120 million into the project, which aims to demonstrate commercial scalability and has already engaged more than 370 UK suppliers. The UK government has committed over £2.5 billion to fusion energy over five years, with £1.3 billion designated for the STEP programme and £740 million for R&D infrastructure.

In the United States, companies like Commonwealth Fusion Systems are utilizing the tokamak method with high-temperature superconductors. As of August 2026, the SPARC research reactor was reported to be nearly 80 percent complete. Additionally, Pacific Fusion has broken ground on a new test site in Albuquerque, New Mexico. Private funding for fusion reached $3.8 billion in the first eight months of 2026, with investment increasingly driven by the energy demands of artificial intelligence from figures and companies including Google, Nvidia, and Sam Altman. For example, Helion Energy aims to supply electricity to Microsoft by 2028.
