hydrogen fusion

Hydrogen fusion is the nuclear process by which hydrogen atoms combine to form helium, releasing enormous amounts of energy.

This reaction powers the sun and other stars, where extreme temperatures and pressures force hydrogen nuclei together.

Scientists have long pursued controlled hydrogen fusion as a potential source of clean, virtually limitless energy on Earth, though sustaining the reaction outside stellar conditions remains technically challenging.

Hydrogen fusion could revolutionize power generation if we can make it practical.
