Company Description

Zap Energy is a private company developing fusion energy technology using a sheared-flow-stabilized (SFS) Z-pinch method. This approach aims to create a compact, scalable fusion reactor that does not require the large, expensive magnets used in more traditional fusion designs. The company is actively producing Z-pinch plasmas across several devices, including its FuZE-3 machine, which has achieved plasma pressures greater than 1 gigapascal. Founded in 2017 by co-founders including Chief Scientist Uri Shumlak and Chief Technology Officer Brian Nelson, the company is headquartered in Everett, Washington, and has focused on advancing its magnet-less fusion concept since its inception.

The company's forward-looking plans are centered on accelerating the path to commercial fusion energy deployment by scaling its technology to achieve a scientific energy gain greater than one (Q>1). Zap Energy is also involved in policy discussions to support a national strategy for fusion commercialization in the United States. Recent progress includes completing its first technical milestone under the U.S. Department of Energy's Milestone-Based Fusion Development Program and publishing peer-reviewed evidence of thermal Z-pinch fusion. The company continues to advance its hardware, commissioning next-generation liquid metal systems and bringing new pulsed-power banks online to support its experimental platforms.
