Zap Energy unveiled its latest fusion device, marking progress in its quest to commercialize fusion power. The startup faces competition from other firms aiming to deliver grid-ready fusion plants by the early 2030s. Fuze-3 achieved record plasma pressure and temperature, critical for achieving energy gain in fusion reactions. These results highlight advancements in sheared-flow-stabilized Z-pinch technology, though direct comparisons with competitors remain challenging. The breakthrough could accelerate Zap’s path toward viable fusion energy solutions.
Key facts
- Zap Energy’s Fuze-3 device reached plasma pressures exceeding 232,000 psi and temperatures over 21 million degrees Fahrenheit.
- The achievement sets a new benchmark for sheared-flow-stabilized Z-pinch fusion technology.
- High-pressure plasmas are essential for meeting the triple product criteria needed for net energy gain.
- Zap still needs to increase plasma pressure tenfold to reach scientific breakeven, a milestone achieved by only one other experiment.
- The company’s new reactor design includes a third electrode, enabling dual power pulses for better plasma control.
