About the solution
Founded by Matsuo and Mori in 2021, EX-Fusion is developing laser fusion technology to generate clean power. This groundbreaking energy source has the capability to deliver substantial power while maintaining environmental sustainability, drawing from the vast resources readily available in seawater. Notably, it matches or even exceeds the power-generating capacity of nuclear fission reactors, all while upholding the safety standards synonymous with conventional renewable energy.
The breakthrough solution created by EX-Fusion addresses global challenges, offering a path to scalable, eco-friendly, carbon-neutral, and secure global power provision. EX-Fusion’s solution addresses the rising global energy demand, a consequence of the high economic growth in emerging nations. The solution also aligns with the transition towards a decarbonized society, in accordance with the Paris Agreement’s commitment to curbing temperature rises to 1.5°C above pre-industrial norms.
EQT Foundation’s Investment
