About

EX-Fusion specializes in laser-based nuclear fusion instead of the more common magnetic confinement method. Their approach allows rapid response to power fluctuations, making it suitable for both baseload and peak power needs. The technology involves precise laser tracking and ignition of deuterium and tritium targets, achieving fusion stably and scalably using seawater as a fuel source. EX-Fusion is Japan’s first laser nuclear fusion company, born out of Osaka University’s Institute of Laser Engineering (ILE), which has lead the global field of laser technology for over 50 years. EX-Fusion maintains their strong relationship with Osaka University as they continue to develop relationships with other players in the industry, like the Graduate School for the Creation of New Photonics Industries (GPI) as well as multiple private sector corporations.

Impact

The commercialization of EX-Fusion’s technology could reduce global CO2 emissions by 4.9 billion tons (approximately 14%) by 2050, supporting a transition to sustainable, non-carbon energy. The laser control technology developed also has applications in various industries, including space debris management and industrial decarbonization​.

• Stabilize target injection and ignition cycles at 10 times a second for consistent power generation.
• Scale up reactor designs for commercialization, with improved efficiency and reliability.
• Address regulatory challenges by advocating for safety standards specific to fusion technology.
• Explore other industrial applications of their laser technologies​
