Sens. John Curtis of Utah and Maria Cantwell of Washington are pushing a new bill to extend a generous Inflation Reduction Act tax credit to fusion energy.

The “Fusion Advanced Manufacturing Parity Act” would amend the IRA’s 45X advanced manufacturing tax credit to components used in fusion energy systems, placing fusion on equal footing with other clean energy technologies like solar and batteries.

“Fusion energy represents the kind of bold, American innovation that built the West and can power our future,” Curtis said. “This bill ensures we’re not just competing in the fusion race, we’re winning it by manufacturing these critical components here at home, creating good-paying jobs and securing our energy independence for the next century.”

Fusion, which envisions generating power through the same reaction that fuels the sun and stars, has never been demonstrated at scale, although multiple companies are aiming to develop first-of-a-kind power plants by the 2030s.
