Helion Energy announced that it has broken ground in Central Washington on what it hopes will be the world's first commercial fusion plant.

The company is still working on a way to reliably generate energy from fusion with its prototype, called Polaris.

Nuclear fusion energy is one step closer to becoming a reality after Helion Energy broke ground Wednesday on what could become the world's first commercial fusion power plant. Construction in Washington state comes after Helion raised $1 billion for its nuclear fusion plant and signed an agreement to provide electricity to Microsoft by 2028.
