Zap Energy

Zap Energy is a fusion energy company focused on developing a compact and scalable Z-pinch fusion platform. The company aims to commercialize fusion power by addressing traditional challenges, such as the reliance on expensive superconducting magnets and high-powered lasers. Its technology seeks to provide a carbon-free energy source with a quicker path to market compared to conventional fusion methods. The core technology, known as sheared-flow-stabilized (SFS) Z-pinch, uses an electrical current to generate a magnetic field that confines and compresses plasma. This innovative approach stabilizes plasma instabilities, allowing for sustained fusion reactions at commercially viable scales. Zap Energy offers modular fusion power plants designed for scalability, a Century platform for testing critical components, and auxiliary systems to manage plasma-facing components. With a leadership team experienced in fusion physics and engineering, Zap Energy is headquartered in Seattle, WA, and has operations in San Diego. The company has raised significant funding to advance its technology and aims to validate net energy gain in its FuZE-Q prototype while scaling its systems for future deployment.
