Fusion Energy

Detailed overview of innovation with sample startups and prominent university research


What it is

Fusion energy is generated by fusing light atomic nuclei, such as isotopes of hydrogen (deuterium and tritium), under extreme temperatures and pressure. This process releases a tremendous amount of energy, far greater than that produced by conventional nuclear fission.

Impact on climate action

Fusion Energy under the theme of Moonshots promises a transformative impact on climate action by offering virtually limitless, clean energy. It aims to reduce carbon emissions drastically, replacing fossil fuels with a sustainable, abundant energy source, thereby mitigating global warming and fostering a sustainable future for generations to come.

Underlying
Technology

  • Plasma Physics: Fusion reactions occur in a state of matter called plasma, where electrons are stripped from atoms, creating an ionized gas. Confining and controlling this superheated plasma is a key technological challenge.
  • Magnetic Confinement Fusion (MCF): The most prevalent approach, MCF utilizes powerful magnetic fields to confine the plasma within a tokamak or stellarator reactor.
  • Inertial Confinement Fusion (ICF): This method uses high-powered lasers or particle beams to compress and heat a small target containing fusion fuel.
  • Deuterium-Tritium Fusion: The most promising fusion reaction for energy production involves fusing deuterium and tritium, which are abundant in seawater and lithium, respectively.
