Deuterium-Deuterium (D-D) Fusion is a type of nuclear fusion reaction where two deuterium atoms combine to form a helium-3 atom, a neutron, and energy.

In Deuterium-Tritium (D-T) Fusion, the fusion of a deuterium atom and a tritium atom results in the formation of a helium-4 (He4) atom and a neutron, along with the release of a significant amount of energy.

Deuterium-Tritium (D-T) Fusion is currently considered the most promising type of fusion reaction for commercial energy production due to its relatively low ignition temperature and high energy output.

Proton-Boron (p-B) Fusion primarily utilizes hydrogen and boron as its fuel sources, undergoing a series of reactions to produce helium and energy.

Helium-3 (He3) Fusion refers to the fusion reaction where two helium-3 atoms combine to form a helium-4 atom, two protons, and energy.

Helium-3 (He3) Fusion offers the advantage of reduced neutron production compared to other fusion reactions, making it potentially safer and easier to manage.

Proton-Boron (p-B) Fusion involves the fusion of a proton and a boron-11 atom, resulting in the formation of three helium-4 atoms and energy.

The primary challenge associated with Proton-Boron (p-B) Fusion is its high ignition temperature, which makes it difficult to achieve and sustain the necessary conditions for fusion to occur.

Deuterium-Helium-3 (D-He3) Fusion refers to the fusion reaction where a deuterium atom and a helium-3 atom combine to form a helium-4 atom, a proton, and energy.

Deuterium-Helium-3 (D-He3) Fusion offers the advantage of abundant fuel sources, as both deuterium and helium-3 are readily available in nature.

Lithium-6 (Li6) Fusion refers to the fusion reaction where two lithium-6 atoms combine to form two helium-4 atoms, two protons, and energy.

The main challenge associated with Lithium-6 (Li6) Fusion is its high ignition temperature, making it difficult to achieve and sustain the necessary conditions for fusion to occur.

Proton-Lithium (p-Li) Fusion refers to the fusion reaction where a proton and a lithium-7 atom combine to form two helium-4 atoms and energy.

Proton-Lithium (p-Li) Fusion offers the advantage of abundant fuel sources, as both hydrogen and lithium are readily available in nature.

Boron-11-Helium-3 (B11-He3) Fusion refers to the fusion reaction where a boron-11 atom and a helium-3 atom combine to form three helium-4 atoms and energy.
