Fusion Energy Startups In Japan

What is Fusion Energy?

Fusion energy is a form of nuclear energy that occurs when two light atomic nuclei combine to form a heavier nucleus, releasing vast amounts of energy in the process. Unlike nuclear fission, which splits heavy atomic nuclei and produces radioactive waste, fusion is cleaner and safer. The primary fuel for fusion is isotopes of hydrogen, such as deuterium and tritium, which are abundant and easily accessible. Fusion energy has the potential to provide a virtually limitless supply of clean energy, making it a cornerstone of future energy solutions.

Key Principles Behind Fusion Energy

The principles of fusion energy revolve around replicating the conditions found in the sun. This involves achieving extremely high temperatures (millions of degrees Celsius) to overcome the repulsive forces between atomic nuclei. Key technologies include magnetic confinement (using devices like tokamaks and stellarators) and inertial confinement (using lasers to compress fuel). The goal is to sustain a controlled fusion reaction that produces more energy than it consumes—a milestone known as "net energy gain."

Core Technologies in Fusion Energy

Japanese startups are leveraging advanced technologies to make fusion energy a reality. Key technologies include:

• Tokamaks: These doughnut-shaped devices use magnetic fields to confine plasma, the hot, ionized gas where fusion occurs. Japan's JT-60SA tokamak is a leading example.
• Stellarators: Similar to tokamaks but with a more complex magnetic field design, stellarators offer improved plasma stability.
• Laser Fusion: Inertial confinement fusion uses high-powered lasers to compress fuel pellets, a technology being explored by startups like EX-Fusion.
• Superconducting Magnets: Essential for creating the strong magnetic fields needed for plasma confinement, Japan is a leader in superconducting magnet technology.
