Key Market Segments

By Technology

• In 2024, Magnetic Confinement led the global fusion energy market, securing over 56.3% of the market share. Its prominence stems from its critical role in major projects like the International Thermonuclear Experimental Reactor (ITER), the world’s most advanced fusion initiative. This technology employs strong magnetic fields to confine plasma, preventing contact with reactor walls and enabling temperatures exceeding 100 million degrees Celsius, essential for sustained fusion reactions.

By Fuels

• Deuterium-Tritium (D-T) dominated the fusion energy market in 2024, capturing more than 63.5% of the market share. The D-T reaction’s high efficiency and lower ignition temperature compared to other fuel pairs drive its preference. Combining deuterium and tritium, both hydrogen isotopes, yields approximately 17.6 MeV per reaction, making D-T the top fuel choice for experimental and prototype fusion reactors globally.

Regional Analysis

• Europe commanded the global fusion energy market in 2024, holding a 44.4% share valued at roughly USD 135.0 billion. This leadership is fueled by significant investments in research infrastructure, effective public-private partnerships, and policies targeting carbon neutrality. Europe’s commitment is highlighted by its role in the ITER project in Cadarache, France, a flagship global energy endeavor.
• The European Commission’s vision for fusion as a safe, cost-effective, and sustainable energy source is advanced through EUROfusion, a consortium of 25 EU countries, the UK, Switzerland, and Ukraine. EUROfusion aligns with the European Research Roadmap to realize fusion energy, aiming to produce grid-ready electricity via a demonstration power plant (DEMO) in the coming decades.
